Effects of Resistance Training on Muscle Strength, Endurance, and Motor Unit According to Ciliary Neurotrophic Factor Polymorphism in Male College Students

摘要: Changes in muscle mass and strength across the adult age span are variable related to ciliary neurotrophic factor (CNTF) genotype. In particular, a single CNTF haplotype (1357 G→A) is important for neuronal muscular developments may be associated with response resistance training. We examined whether genotype differentially influences effect of training on neuromuscular improvement male college students. Resistance upper extremities comprised 3 sets at 75%-85% intensity per 1 repetition maximum, times week, total 8 weeks. measured isokinetic function elbow joint regard (60°/s) endurance (180°/s) by using an dynamometer. The biceps brachii (BB) brachioradialis muscles were studied surface electromyography spike-triggered averaging assess surface-detected motor unit potential (SMUP) area. After training, SMUP BB increased significantly 60°/s (p < 0.05), but no difference was observed. 180°/s GG/AA group compared that GA 0.05). average power flexor after again, Thus, improvements have resulted directly from rather than genetic factors nerves tissue. Key PointsResistance improves young men.This irrespective genotypes.
