(Elsevier, 2024) Sañudo Corrales, Francisco de Borja; Sanchez Trigo, Horacio; Domínguez Herrera, Raúl; Flores Aguilar, Gonzalo; Sánchez Oliver, Antonio Jesús; Moral, Jose E; Oviedo-Caro, Miguel Ángel; Educación Física y Deporte; Motricidad Humana y Rendimiento Deportivo; HUM1061: Inclusión Social, Educación Física y Deporte, y Políticas Europeas en Investigación
Introduction The integration of gamification in mHealth interventions presents a novel approach to enhance user engagement and health outcomes. This study aims to evaluate whether comparison-oriented gamification can effectively improve various aspects of health and well-being, including physical activity, sedentary behavior, sleep, and overall quality of life among young adults. Methods Potential 107 young adults (from 19 to 28 years old) participated in an 8-week trial. Participants were assigned to either a gamified mHealth intervention (LevantApp) with daily leaderboards and progress bars (n = 53, 26 % dropped-out), or a control condition without gamification (n = 52, 29 % dropped-out). Physical activity (number of steps, moderate and moderate-to-vigorous physical activity -MVPA-) and sleep quantity were measured objectively via accelerometry and subjectively using the International Physical Activity Questionnaire(IPAQ), Pittsburgh Sleep Quality Index(PSQI), Sedentary Behavior Questionnaire(SBQ), and Short Form Health Survey(SF-36). Results This mHealth intervention with social comparison-oriented gamification significantly improved moderate physical activity to a greater extent than the control group. Additionally, the intervention group showed improvements in the number of steps, moderate physical activity, sedentary time, emotional wellbeing, and social functioning. However, no significant group by time interaction was observed. No significant differences were observed in sleep quality or quantity. Conclusion s: The LevantApp gamified mHealth intervention was effective in improving moderate physical activity, physical functioning, and role-emotional in young adults. No significant effects were found on step counts, MVPA or sleep, suggesting that while gamification can enhance specific aspects of physical activity and quality of life, its impact may vary across different outcomes.

La actividad física es crucial para la salud pública debido a sus numerosos beneficios. Esta investigación busca diagnosticar los niveles de condición física en jóvenes que asisten a gimnasios particulares en La Habana. Se destaca la importancia de una adecuada planificación y evaluación de los entrenamientos. Se utilizó un diseño no experimental y un estudio descriptivo de corte transversal. La muestra consistió en 50 jóvenes de 19 a 24 años, y se entrevistaron 15 entrenadores. Los resultados del Cuestionario Internacional de Actividad Física (IPAQ) mostraron que los practicantes tenían altos niveles de actividad física. Sin embargo, las pruebas de condición física revelaron que tenía resultados pobres en el Test de Ruffier y los Test de Fuerza y Flexibilidad. Destacar que solo un bajo por ciento de los entrenadores encuestados tenía formación académica en Cultura Física. La investigación concluye que existe una discrepancia significativa entre los niveles de actividad física reportados y los resultados de las pruebas de condición física. Es necesario mejorar la capacitación de los entrenadores y la planificación de los entrenamientos en los gimnasios particulares para optimizar la salud de los jóvenes
Optimal dose and type of physical activity to improve glycemic control in people diagnosed with type 2 diabetes: a systematic review and meta-analysis
(Amer Diabetes Assoc, 2024) Gallardo Gomez , Daniel; Salazar-Martinez, Eduardo; Alfonso Rosa, Rosa Mª; Ramos Munell, Javier; Pozo Cruz, Jesús del; Del Pozo Cruz, Borja; Álvarez Barbosa, Francisco; Motricidad Humana y Rendimiento Deportivo; Educación Física y Deporte; HUM1055: Epidemiology of Physical Activity and Fitness Across Lifespan
The optimal dose or type of physical activity to control glycosylated hemoglobin (HbA1c) in people with diabetes remains unknown. Current guidelines do not include consideration of baseline HbA1c for activity prescription. PURPOSE To examine the dose-response relationship between physical activity and HbA1c (%) in individuals with type 2 diabetes.DATA SOURCES A systematic search was performed in Embase, MEDLINE, Scopus, CINAHL, SPORTDiscus, and Web of Science. STUDY SELECTION We included trials that involved participants diagnosed with type 2 diabetes that included any type of physical activity as intervention DATA EXTRACTION Pre- and postintervention HbA1c data, population and interventions characteristics, and descriptive statistics were collected to calculate change scores for each study arm. DATA SYNTHESIS We used Bayesian random-effects meta-analyses to summarize high-quality evidence from 126 studies (6,718 participants). The optimal physical activity dose was 1,100 MET min/week, resulting in HbA1c reductions, ranging from −1.02% to −0.66% in severe uncontrolled diabetes, from −0.64% to −0.49% in uncontrolled diabetes, from −0.47% to −0.40% in controlled diabetes, and from −0.38% to −0.24% in prediabetes. LIMITATIONS The time required to achieve these HbA1c reductions could not be estimated due to the heterogeneity between interventions’ duration and protocols and the interpersonal variability of this outcome. CONCLUSIONS The result of this meta-analysis provide key information about the optimal weekly dose of physical activity for people with diabetes with consideration of baseline HbA1c level, and the effectiveness of different types of active interventions. These results enable clinicians to prescribe tailored physical activity programs for this population.

(Human Kinetics Publishers, 2020) Álvarez Barbosa, Francisco; Pozo Cruz, Jesús del; Del Pozo-Cruz, Borja; García Hermoso, Antonio; Alfonso Rosa, Rosa Mª; Educación Física y Deporte; Motricidad Humana y Rendimiento Deportivo; HUM1055: Epidemiology of Physical Activity and Fitness Across Lifespan
The aim of this study was to quantify the effect of whole-body vibration (WBV) on balance, functional mobility, gait, functional performance and quality of life in institutionalized older people. Eight databases were systematically reviewed as recommended by the Cochrane Collaboration. This systematic review was designed to answer the acronym set by the PICO- model. Ten Randomized Controlled Trials were included in the meta-analysis. Analysis of the mean differences of the functional mobility assessed with TUG test was MD = -2.49 sec (95% CI -4.37 to -0.61) (I2=68%). In 279 participants from five studies the overall mean difference was MD = 0.49 [95% CI, -0.13 to 1.11] (I2=23%) for gait, and MD = 0.96 [95% CI, -0.45 to 2.37] (I2=85%) for balance which represents the total Tinetti score MD = 1.59 [95% CI, −0.52 to 3.70] (I2=82%). In summary, WBV could have benefits on functional mobility in institutionalized older people
Impact of Social Isolation on Physical Functioning among Older Adults: A 9-year 1 Longitudinal Study of a US-Representative Sample
(Human Kinetics Publishers, 2020) Álvarez Barbosa, Francisco; Pozo Cruz, Jesús del; Del Pozo-Cruz, Borja; García Hermoso, Antonio; Alfonso Rosa, Rosa Mª; Educación Física y Deporte; Motricidad Humana y Rendimiento Deportivo; HUM1055: Epidemiology of Physical Activity and Fitness Across Lifespan
Introduction. Social isolation among older adults is associated with poor health and premature mortality, but its impacts on physical functioning are not fully understood. Previous studies have typically relied on community samples, cross-sectional data, and/or suboptimal prospective designs. This study generated more robust evidence by investigating the longitudinal associations between social isolation and physical functioning in a large panel of older adults.Methods. The analyses were based on nine waves of data (2011-2019) from a sample of adults aged 65+ years from the US National Health and Aging Trends Study (n=12,427 34 individuals; 54,860 person-year observations) and within-individual fixed-effect panel regression models. Analyses were conducted in 2020. Social isolation was measured using the Social Isolation Index (SII) and physical functioning was measured through the Short Physical Performance Battery (SPPB). Results. In fully-adjusted fixed-effect regression models, each one-unit increase in the SII 40 resulted in an average decrease of 0.27 units in the SPPB (95%CI=−0.31, −0.24). This relationship was moderated by age, with the SII bearing a significantly and substantially stronger influence on the SPPB at older than younger ages.Conclusions. This study confirmed that social isolation is associated with deficits in physical functioning among older adults in the US using more robust data and methods than earlier studies. These findings highlight the importance of incorporating strategies to reduce social 4isolation in policies aimed at promoting successful aging.
1 Lifestyle behaviors predict adolescents bullying victimization in low and middle-income countries
(Elservier, 2020) Alfonso Rosa, Rosa Mª; García Hermoso, Antonio; Sanders, Taren; Parker, Phil; Oriol Granado, Xavier; Arnott, Hugh; del Pozo Cruz, Borja; Motricidad Humana y Rendimiento Deportivo; HUM1055: Epidemiology of Physical Activity and Fitness Across Lifespan
In this study we aimed to provide a global perspective of the association between different lifestyle behaviors and bullying in school adolescents and to ascertain whether or not the Human Development Index moderated those associations. Data from the Global school-based Student Health Survey were analyzed in 273 121 from 82 countries. Logistic regression was applied to determine country-specific bullying victimization probability from meeting the recommended guidelines for physical activity, excessive sitting time, physical education attendance and active transport. Meta-analysis was then undertaken to ascertain pooled global effect estimates of the relationship between these behaviors and bullying victimization. Linear regression was used to study the relationship between odds of bullying from meeting the lifestyle guidelines and the Human Development Index. Our estimates indicate that excessive sitting time [1.38 (1.34,1.41)], attendance to physical education [0.87 (0.85,0.89)], and active transport [0.94 (0.91,0.97)] but not overall physical activity [1.01 (0.99,1.04)] were associated with bullying in the study sample. The probability of being bullied from excessive sitting time linearly decreased with Human Development Index. Excessive sitting time is associated with increased odds of bullying among adolescents. Active commuting and attendance to physical education play a protective role for bullying, while physical activity does not
Effectiveness of different types of exercise based-interventions in sarcopenia: A systematic review and meta-analysis
(Elservier, 2025) Ceballo Sánchez, José Luis; Gallardo Gómez, Daniel; Alfonso Rosa, Rosa Mª; Pozo Cruz, Borja del; Ramos-Munell, Javier; Pozo Cruz, Jesús del; Motricidad Humana y Rendimiento Deportivo; Educación Física y Deporte; HUM1055: Epidemiology of Physical Activity and Fitness Across Lifespan
Background: Sarcopenia is one of the most prevalent and disabling health conditions in older adults associ- ated with muscle mass loss and a reduced ability to perform daily-living activities. Although evidence sup- ports the use of exercise interventions to reduce the impact of sarcopenia, the most effective type of physical exercise remains unknown. The objectives of this review were (1) to determine the effectiveness of physical exercise at overall and type-specific levels on the physical performance and muscular strength of older adults with sarcopenia, and (2) to detect potential effect modifiers such as age and sex. Methods: Three databases (i.e., PubMed, Web of Science, and Scopus) were used to conduct the searches. We included randomised controlled trials where exercise-based interventions were applied to participants aged 65 and over diagnosed with sarcopenia using the EWGSOP2 or AWGSOP2 criteria. Bayesian meta-analyses were performed to pool the evidence using standardised mean changes from baseline [SCFB] for physical performance and mean changes from baseline for muscle strength as effect measures. The risk of bias was assessed using the revised Cochrane risk-of-bias tool. Results: Evidence from 28 studies (2582 participants) showed that physical exercise was effective to improve the physical performance (SCFB = 0.21; 95 % CrI 0.08 to 0.33) and muscular strength (Kg grip strength gain = 2.50; 95 % CrI 0.32 to 4.63) of older adults with sarcopenia. Resistance-based interventions presented a meaningful treatment effect on physical performance (SCFB = 0.23; 95 % CrI 0.10 to 0.36). Age and sex mod- ified the effects of physical exercise on both outcomes. Conclusions: This meta-analysis supported the use of physical exercise to improve the physical performance and muscular strength of people with sarcopenia. Resistance-based interventions were the most effective type of activities in both outcomes. Physical exercise effects may vary between males and females older adults. These findings should inform policymakers and healthcare providers in developing more targeted and efficient physical exercise programs (resistance based interventions) to enhance functional indepen- dence and reduce the risk of falls in older adults with sarcopenia
Optimal dose and type of physical activity to improve functional capacity and minimise adverse events in acutely hospitalised older adults: a systematic review with dose-response network meta-analysis of randomised controlled trials
(Bmj Publishing Group, 2023) Gallardo Gómez, Daniel; Pozo Cruz, Jesús del; Pedder, H; Alfonso Rosa, Rosa Mª; Álvarez Barbosa, Francisco; Noetel, M; Jasper, U; Chastin, S; Ramos Munell, Javier; Cruz, BD; Educación Física y Deporte; Motricidad Humana y Rendimiento Deportivo; HUM1055: Epidemiology of Physical Activity and Fitness Across Lifespan
Objective To identify the optimal dose and type of physical activity to improve functional capacity and reduce adverse events in acutely hospitalised older adults. Design Systematic review and Bayesian model-based network meta-analysis. Data sources Four databases were searched from inception to 20 June 2022. Eligibility criteria for selecting studies Randomised controlled trials that assessed the effectiveness of a physical activity-based intervention on at least one functional outcome in people aged ≥50 years hospitalised due to an acute medical condition were included. Pooled effect estimates (ie, standardised mean differences for functional capacity and the ratio of means for adverse events) were calculated using random treatment effects network meta-analysis models.Results Nineteen studies (3842 participants) met the inclusion criteria. Approximately 100 Metabolic Equivalents of Task per day (METs-min/day) (~40 min/day of light effort or ~25 min/day of moderate effort activities) was the minimal dose to improve the functional capacity of acute hospitalised older adults (standardised mean difference (SMD)=0.28, 95% credible interval (CrI) 0.01 to 0.55). The optimal dose was estimated at 159 METs-min/day (~70 min/day of light effort or ~40 min/day of moderate effort activities; SMD=0.41, 95% CrI 0.08 to 0.72). Ambulation was deemed the most efficient intervention, and the optimal dose was reached at 143 METs-min/ day (~50 min/day of slow-paced walking; SMD=0.76, 95% CrI 0.35 to 1.16), showing a high evidential power (87.68%). The minimal effective ambulation dose was estimated at 74 METs-min/ day (~25 min/day of slow-paced walking; SMD=0.25, 95% CrI 0.01 to 0.41). Physical activity interventions resulted in a decrease in the rate of adverse events compared with usual care at discharge (ratio of means=0.96, 95% CrI 0.95 to 0.97; median time 7 days). Conclusions This meta-analysis yielded low to moderate evidence supporting the use of in-hospital supervised physical activity programmes in acutely hospitalised older adults. As little as ~25 min/day of slow-paced walking is sufficient to improve functiona ¡capacity and minimise adverse events in this population. Trial registration number PROSPERO CRD42021271999

(Federacion Espanola de Asociaciones de Docentes de Educacion Fisica, 2025) Muñoz Llerena, Antonio; Muñoz Llerena, Esperanza; Fernández Gavira, Jesús; Alcaraz Rodríguez, Virginia; Motricidad Humana y Rendimiento Deportivo; Educación Física y Deporte; HUM1061: Inclusión Social, Educación Física y Deporte, y Políticas Europeas en Investigación
Introduction: Dance offers multiple benefits for primary school students and can serve as a strong link between Physical Education and Music Education. However, there is limited literature analyzing the role of dance in interdisciplinary educational projects. Objective: The main objective of this study was to understand the perceptions of Physical Education and Music Education teachers regarding interdisciplinarity and the role of dance as a unifying element between these subjects. Methodology: Following a phenomenological design, semi-structured interviews were conducted with four primary school teachers of Physical Education and Music Education from a subsidized school. The data were analyzed using thematic analysis. Results: The findings revealed that dance provides numerous benefits for students, including improved coordination, rhythm, movement, and balance. Teachers emphasized the importance of coordination between educators, the availability of adequate spaces, and student motivation for the success of interdisciplinary projects. Discussion: The results align with previous studies that highlight the potential of dance to enhance student motivation and engagement in both Physical Education and Music Education. The integration of dance in teaching practices facilitates holistic learning experiences that encompass cognitive, physical, and emotional development. Conclusions: Dance effectively serves as an interdisciplinary link between Physical Education and Music Education, promoting student motivation and teacher collaboration. These findings contribute to the broader discourse on the educational value of dance and its role in fostering interdisciplinary learning

(2025) Bachero Mena, Beatriz; Rodiles Guerrero, Luis; Sánchez Valdepeñas, Juan; Cornejo Daza, Pedro Jesús; Cano Castillo, Clara; Pareja Blanco, Fernando; Sánchez Moreno, Miguel; Motricidad Humana y Rendimiento Deportivo
This study aimed to analyze the evolution of repetition velocity throughout a set until failure in the bench-press exercise and to analyze the relationships between the percentage of performed repetitions (%Rep) regarding the maximum number of repetitions that can be completed (MNR) and the percentage of velocity loss (VL) in women. Sixteen women performed one set until failure with four different intensities (50%, 60%, 70%, and 80% of one-repetition maximum, 1RM). Two-testing sessions were performed with 50% and 80% 1RM to evaluate data stability. The level of significance was set at p ≤ 0.05. A close relationship was observed between the magnitude of VL and the %Rep (R2 = 0.85–0.92) and a low standard error of the estimation (6.85–9.81%). Regarding reliability, the MNR showed a coefficient of variation (CV) of 16.1% and 20.8% for 50% and 80% 1RM, respectively. Regarding the %Rep for a given VL (from 15% VL), CVs were: 6.3–19.6%, being higher when VL reached in the set was lower. This study shows the usefulness of monitoring VL to estimate, with considerable precision, the %Rep in women. However, the %Rep when a given VL was reached revealed only satisfactory absolute reliability from a certain VL threshold (>15% VL)
Factors influencing sports dropout rate among adolescent girls: a study on self-perceptionand sports identity
(Federación Española de Docentes de Educación Física (FEADEF), 2025) Moreno Vitoria, Laura; Cabeza Ruiz, Ruth; Antón González, Laura; Pellicer Chenoll, Maite; Motricidad Humana y Rendimiento Deportivo; HUM1097: FEMINAE: Feminismo, Educación, Motricidad e Investigación
Introduction: Adolescence is a crucial period marked by changes at the physical, psychological, emotional and social levels. During this time, adolescent girls’ sports dropout rates are partic-ularly high, and they generally engage in sports less often and less regularly than boys do. Ob-jective: to analyze self-perception and sports identity among a group of adolescent athletes. Methodology: A cross-sectional study was carried out and these variables were recorded using two standardized scales on a sample of 217 registered athletes.Results: The results showed significant differences between girls and boys in their self-percep-tion of competence, autonomy and sport identity, potentially related to gender-differentiated socialization regarding the traditional concepts of masculinity and feminity. They also showed that gender stereotypes should be abolished to equalize girl athletes’ identity development, im-prove their sporting experience and reduce their dropout rate.Discussion: These findings emphasize the impact of gendered socialization and stereotypes on girls' self-perception and sports identity. Addressing these issues through targeted interven-tions could foster more equitable sporting experiences and reduce dropout rates among ado-lescent female athletes.Conclusions: The study found lower self-perception and sports identity in adolescent girls, linked to gender stereotypes and androcentricin sports, emphasizing interventions to reduce girls' athlete dropout rates
Women athletes’ representation on Instagram: A feminist critical discourse analysis of Spanish media coverage during the Paris 2024 Olympics
(Sage Publications, 2025) Castro Lemus, Nuria; Ortiz-Romero, Mayte; Ramos Ruiz, Álvaro; Motricidad Humana y Rendimiento Deportivo; SEJ596: Feminism, Entrepreneurship and Innovation in Exercise
Media coverage plays a crucial role in gender equality within sports. A common concern in sports news is the under-representation of women and the focus on non-sporting aspects, such as their aesthetics or personal lives. Based on the aforementioned arguments, this study aimed to analyze the representation of women athletes through Instagram narratives in Spanish sports media during the period corresponding to the Paris 2024 Olympic Games. The data collected consisted of 241 posts from Marca, Relevo Deportes, and La Tarjeta Morada, framed in the period corresponding to the Olympics. The methodology employed in this study is primarily qualitative, incorporating quantitative data to provide contextual background for the findings. While the frequency of publications and audience interactions were quantified to outline general trends, the core of the analysis relies on Critical Discourse Analysis (CDA) to examine the narratives in depth. The findings not only confirm that women are under-represented in sports media, but also that the coverage reinforces traditional roles and stereotypes through gender-bland sexism and femvertising. Furthermore, the media's focus is still mainly on their personal lives, emotions and aesthetics, while the excessive use of the term “feminine” regarding sports contributes to the gap. In conclusion, this study highlights the need for critical thinking and feminist media literacy as pedagogical tools to avoid unequal discourses
Does beetroot juice supplementation affect to sport performance in high performance female vollyball players?
(Universidad Católica San Antonio de Murcia, 2025) López León, Inmaculada; Moreno Lara, Javier; Sánchez Oliver, Antonio Jesús; Rico Saborido, Esteban; Muñoz López, Alejandro; Muñoz Llerena, Antonio; Muñoz Llerena, Antonio; Domínguez Herrera, Raúl; Motricidad Humana y Rendimiento Deportivo; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
It has been suggested that the response to beetroot juice supplementation (BRJ) may be mediated by sex, but research is limited on studies focused on the effect of this supplement on explosive efforts in female athletes. Thus, the aim of this study was to analyze the effect of BRJ on sports performance in female volleyball layers. Twelve female (22.9 ± 3.6 years) high-performance volleyball players (Spain Superliga 2) randomly ingested an enriched nitrate BRJ (12.8 mmol NO3-) or a depleted NO3- placebo (PLA) in two experimental sessions. In each experimental session, participants performed different sports performance tests such as countermovement jump (CMJ), block jump (BJ), attack jump (AJ), a modified T-test, and a 5-0-5 test. The results reported a statistically significant enhancement in CMJ after BRJ compared to PLA (BRJ: 31.89 ± 2.84 cm vs. PLA: 31.48 ± 2.37 cm; p = .044; d = 0.66), but no significant differences were reported for the other tests used. The findings suggest that BRJ supplementation may enhance vertical jump performance (CMJ) in female volleyball players, but it did not lead to significant improvements in volleyball-specific actions (i.e., BJ and AJ), agility, or acceleration
Use of nutritional supplements in amateur tennis players
(Editura Universitatea din Pitesti, 2018) Sánchez Oliver, Antonio Jesús; Mata-Ordoñez, Fernando; Domínguez Herrera, Raúl; López Samanes, Álvaro; Motricidad Humana y Rendimiento Deportivo; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
Literature on the use of nutritional supplements (NS) in tennis players is scarce. The objective of the present study was to evaluate NS consumption in a group of men's tennis players who participated in the 2016 Andalusian team championship. A total of 70 questionnaires from 7 different clubs were registered. The questionnaire was previously designed and evaluated through piloting in which the validity of the content, its application, its structure and its presentation were observed. The results showed that 100% of the sample group was in favor of NS consumption within the law, 88.6% claimed to have consumed them at some time and 61.4% presently consume them. The NS most consumed by study participants were sports drinks (69.35%), energy bars (29%), a vitamin complex (19.35%), protein (serum) (17.74%) and creatine (14.51%). A high percentage of NS consumers thought that they had obtained positive results from NS consumption. The percentages and the findings regarding NS consumption in the present study were similar to the contributions made by other studies which evaluated supplementation in athletes, although with some subtle differences
Análisis del rendimiento en jóvenes nadadores tras un entrenamiento de alto volumen de 12 semanas
(Universidadd de Coruña, 2025) Nahar, Natasja; González Jurado, José Antonio; Da Silva, Sandro Fernandes; Sánchez Oliver, Antonio Jesús; Motricidad Humana y Rendimiento Deportivo
Las prácticas tradicionales de entrenamiento en natación suelen implicar volúmenes de trabajo elevados. El presente estudio tiene como objetivo analizar el impacto de un programa de entrenamiento de 12 semanas de alto volumen y baja intensidad en el rendimiento deportivo de jóvenes nadadores que participan en competiciones oficiales, comparando los resultados obtenidos según las diferentes categorías de edad y por sexo. Un total de 144 nadadores menores de edad (68 hombres y 76 mujeres) participaron en este estudio. Se comenzó con un volumen inicial de 3.750-7.500 metros semanales según la categoría, aumentando un 5% por mesociclo. La intensidad se controló mediante el tiempo inicial para el estilo libre (65-75%) y la frecuencia cardiaca máxima en el resto de estilos (60-70%). Se registraron mejoras significativas en los tiempos de todas las categorías a lo largo de la intervención. Todas las categorías mejoraron las marcas pre-post (tanto considerando toda la muestra, como análisis diferenciado por sexo), sin embargo, no se encontraron diferencias significativas en las mejoras entre categorías. En conclusión, un entrenamiento de alto volumen de 12 ha demostrado tener efectos positivos en el rendimiento de los niños y adolescentes que compiten en natación, siendo más notables en las edades más tempranas. Aunque se registraron mejoras en ambos sexos al dividirlos por categorías, estas fueron más pronunciadas en las mujeres.
Consumo de suplementos deportivos en levantadores de peso de nivel nacional
(Federación Española de Asociaciones de Docentes de Educación Física (FEADEF), 2018) Puya Braza, José María; Sánchez Oliver, Antonio Jesús; Motricidad Humana y Rendimiento Deportivo
La literatura científica sobre el consumo de suplementos deportivos (SD) en levantamiento de potencia es escasa. El objetivo del presente estudio fue evaluar el consumo de SD y la ingesta de proteína dietética en un grupo de levantadores de peso que compiten a nivel nacional. Se utilizaron enfoques experimentales y no experimentales, registrándose un total de 22 cuestionarios y diarios dietéticos. Los resultados muestran que el 100% de los sujetos afirma haberlos consumido en alguna ocasión y el 96,9% los consume en la actualidad. Los SD más consumidos por la muestra son monohidrato de creatina (100%), cafeína (95%), proteína de suero (92%), aminoácidos ramificados (73%), barritas energéticas (68%), ácidos grasos omega-3 (63%), bebidas isotónicas (63%) y complejos vitamínicos (59%). La mayoría (36,4%) no prevé en qué momento del día consumirlos. Durante el transcurso del diario dietético, los SD más consumidos fueron la proteína de suero y el monohidrato de creatina; además, los sujetos ingirieron una media de 2.37 g/kg/día de proteína dietética. Teniendo en cuenta el presente estudio y otras aportaciones en la bibliografía, podemos afirmar que la ingesta de proteína dietética en levantadores de peso es suficiente para la ganancia y preservación de masa muscular; y que el consumo de SD es elevado y cada vez más frecuente, lo que puede ocasionar serios riesgos de salud pública debido a la falta de información existente en el sector, e inespecífica y mejorable legislación de los SD en Europa
Management of new forms of sports habits in an immigrant population during the acculturation process
(Editura Universitatea din Pitesti, 2018) Fernández Gavira, Jesús; Sánchez Oliver, Antonio Jesús; Grimaldi Puyana, Moisés; García Fernández, Jerónimo; Motricidad Humana y Rendimiento Deportivo; HUM1061: Inclusión Social, Educación Física y Deporte, y Políticas Europeas en Investigación; SEJ525: Gestión e Innovación en Servicios Deportivos, Ocio y Recreación
The immigrant population in Europe is today a reality. It currently has up to two and a half million foreigners (third countries), with Germany and the United Kingdom having the most (Eurostat, 2015). The result of this is a community within the society that is unified by its lack of basic necessities in all areas of life. This includes sports, an area where more attention is required. Therefore, the aim of this investigation is to address the lack of knowledge on this subject and to lay some groundwork for future research. The main aspects studied in depth are: the nature of the sports played, the types of competition, amenities, sports related cultural expressions, needs as a community and many more. The findings of this research were collected by means of surveys, extensive interviews, focus groups and expert panels. Furthermore, the inclusion of the immigrant community, sports policy makers and experts in the field has led to the creation of a dialog between the participants involved, through a series of strategically composed questions. All the information gathered throughout the research stage has been methodically collated and developed. It concludes in a series of recommendations and proposals on how to make progress in integrating this community in the coming years
The Timeout in Sports: A Study of Its Effect on Volleyball

The purpose of this study was to analyse the variables (lost rallies and score difference) that determine the timeout effect (positive or no effect) in volleyball, in balanced and unbalanced sets. 232 timeouts, requested by the coaches of 66 male and female teams participating in the Spanish Championship in the Under-14 and Under-16 categories, were analysed. The variables considered in this study were timeout effects, lost rallies and score differences. To analyse the timeout effect, a binary logistic regression model was applied. The results of this model show that, in balanced sets, the variables that predict the timeout effect are the number of rallies (≤2 lost rallies) and the score difference (2–3 points), whilst in unbalanced sets, and the variable that predicts the timeouteffect is the number of lost rallies (3 lost rallies). These results show the importance of bearing these variables in mind when timeouts are managed and requested by coaches, in order to optimise the team’s performance

This study aimed to analyze the effects of padel match play on circulating substrates, metabolites, energy balance enzymes, and muscle damage biomarkers and evaluate possible sexrelated differences. Twenty-two trained padel players (13 female and 9 male young-adult players) were recruited for this study in which simulated padel matches were analyzed. Circulating levels of substrates (glucose -BG- and triglycerides -TGs-), metabolites (creatinine -Cr- and urea), energy balance enzymes (lipoprotein lipase -LPL-), and muscle damage biomarkers (creatine kinase -CK-, lactate dehydrogenase -LDH-, and fatty acid-binding protein 3 -FABP-3-) were assessed both pre- and post-padel competition. Time analysis of padel matches reported a real time–total time ratio of 0.4. Moreover, players’ mean heart rate during padel matches represented around 75% of their individual maximum value. Unaltered BG levels and a slight decrease in TGs were observed post-exercise. Cr, urea, LPL, CK, LDH, and FABP-3 levels increased after padel matches when total group was considered. Moreover, sex-related differences in Cr, CK, and LDH blood concentrations were found in both pre- and post-padel competition. According to our results, the padel competition could be defined as a low- or moderate-impact sport in which aerobic energy system contribution is prevalent although anaerobic metabolism also plays a key role in performing padel shots and other explosive actions. Considering that male and female players exercised at the same relative intensity during padel matches, sex differences found in muscle damage biomarkers could be due to the greater muscle mass in males
