Abstract
Muscle fibers damage following vigorous resistance exercises can disrupt athletes' performance and delay their recovery. Taking dietary supplements can reduce the amount of these cellular injuries. The aim of the present study was to evaluate the effect of short-term ganoderma lucidum supplementation on creatine kinase [CK] enzyme and muscle strength in young active men.
In a crossover, randomized, double-blind and counterbalanced design, 10 active men (age: 22.25±2.91 years; weight: 67.67±8.65 kg; body fat: 10.75±3.88 %) participated in two trials of water-soluble ganoderma lucidum (5.5 g/kg) and placebo (maltodextrin) for three days before a 36-minute vigorous resistance exercise (85% 1-RM) including leg extension, hamstring leg flexion, lat pull-down, one dumbbell triceps extension, biceps cable curl, and chest press. The performance speed was including 2 seconds for contractions and 4 seconds to extension.
Analyze of variance (ANOVA) test with repeated measurements and Bonferroni post-hoc test showed that CK enzyme level and muscle strength decreased significantly after 24 hours of exercise compared to immediately after vigorous resistance exercise. Compared to placebo, this difference was significant in two variables (p<0.05). There was no significant effect on chest press motion.
Short-term supplementation of ganoderma lucidum before a single bout vigorous resistance exercise may have been effective in decreasing the level of cellular injury and increasing the production of maximal muscle force (muscle strength) one day after intensive exercise in young active men. Therefore, a moderate dose of this supplement is recommended for those who are undergoing vigorous resistance exercise.
