dc.description.abstract | Dietary nitrate (NO3
−) supplementation, which can enhance performance in exercise
settings involving repeated high-intensity efforts, has been linked to improved skeletal muscle
contractile function. Although muscular strength is an important component of explosive movements
and sport-specific skills, few studies have quantified indices of muscular strength following NO3
−
supplementation, particularly isokinetic assessments at different angular velocities. We performed a
systematic review and meta-analysis to determine whether dietary NO3
− supplementation improves
peak torque, as assessed by the gold standard method of isokinetic dynamometry, and if this effect
was linked to the angular velocity imposed during the assessment. Dialnet, Directory of Open
Access Journals, MEDLINE, PubMed, SciELO, Scopus, and SPORTDiscus were searched for articles
using the following search strategy: (nitrate OR beet*) AND (supplement* OR nutr* OR diet*) AND
(isokinetic OR strength OR “resistance exercise” OR “resistance training” OR “muscular power”).
The meta-analysis of data from 5 studies with 60 participants revealed an overall effect size of −0.01
for the effect of nitrate supplementation on isokinetic peak torque, whereas trivial effect sizes ranging
from −0.11 to 0.16 were observed for independent velocity-specific (90◦
/s, 180◦
/s, 270◦
/s, and 360◦
/s)
isokinetic peak torque. Four of the five studies indicated that dietary NO3
− supplementation is not
likely to influence voluntary knee extensor isokinetic torque across a variety of angular velocities.
These results suggest that NO3
− supplementation does not influence isokinetic peak torque, but
further work is required to elucidate the potential of NO3
− supplementation to influence other indices
of muscular strength, given the dearth of experimental evidence on this topic. | es |
