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.
Notes
grade-a
Beta-Alanine
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
Creatine
Minor High See all 3 studies
Somewhat effective.
grade-b
Spirulina
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

All comparative evidence is now gathered in our ​A-to-Z Supplement Reference.

The evidence for each separate supplement is still freely available ​here.
grade-b
Trimethylglycine
 
grade-c
Chromium
