Creatine supplementation differentially affects maximal isometric strength and time to fatigue in large and small muscle groups

Article Abstract:

Creatine (CR) supplementation seems to increase time to fatigue and maximal strength in isometric exercise, but only for movements performed with a large muscle mass. CR supplementation affects time to fatigue and maximal isometric strength in small and large muscle groups differently based on data from a double-blind study. Supplementation significantly increased maximal isometric strength in knee extension, but not in handgrip exercise. Supplementation increased time to fatigue in each of the three bouts of submaximal knee extension and handgrip exercise vs the placebo trials.

The effects of caffeine on the maximal accumulated oxygen deficit and short-term running performance

Article Abstract:

A test involving nine active male athletes indicated that using caffeine increases the maximal accumulated oxygen deficit and delays the onset of exhaustion in a short run. Five mg of caffeine per 1 kg of body mass was administered one hour before the run. A placebo was administered to a control group. Results indicate caffeine directly influences the nervous system and active muscles.

Effect of acute resistance exercise on postexercise oxygen consumption and resting metabolic rate in young women

Article Abstract:

Young women participants were required to engage in a series of intense weight lifting tasks. Post-exercise measurements indicated an elevation of resting metabolic rate and fat oxidation during a 16-hour recovery period.
