Muscular Endurance

Muscular endurance tends to refer to the capacities of a muscle tissue to continuously exert itself during one 'set' of exercises, and improvements in muscular endurance are thought to reflect antifatigue effects.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect muscular endurance
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
grade-a Minor Very High See all 8 studies
The lone meta-analysis suggests a small benefit: a median 2.85% increase in muscular endurance when exercising for 60-240 s (usually measured by time to exhaustion).
grade-b Minor High See all 3 studies
Somewhat effective.
grade-b Minor High See all 3 studies
Studies currently assessing the effects of spirulina on muscular endurance are too hetereogeneous to properly assess potency thereof. However, a positive effect does appear to exist
grade-b - High See all 3 studies
There may be a small benefit in prolonged and exhaustive resistance training with betaine relative to placebo, but at this moment in time most evidence assessing muscular endurance has failed to find a statistically significant increase (trends to improve do seem apparent).
grade-c - - See study
Low dose chromium supplementation failed to promote muscular endurance in trained athletes relative to placebo.
grade-c - - See study
Supplementation of colostrum, relative to whey protein, does not appear to promote greater increases in muscular endurance (as assessed by bench press repetitions) when taken alongside a training regimen.
