Abstract
Aim: The growth factor myostatin and IGF-1 play a major role in response to muscular contractions and in the regulation and stimulation of muscles metabolism. This research aim is to study the effects of ginseng on the myostatin and IGF-1.
Method: Therefore, 16 athletes were selected. The research was constructed as a two-way blinded semi- experimental, pre-post test with a control group. Participants were divided into two groups: Ginseng and placebo. Blood sampling was done before and after one month supplementation and after a simulated competition.Data analysis was done by repeated measures analysis of variance, LSD post hoc and independent T-test.
Results: Results showed that level of myostatin and IGF-1 were influenced by using ginseng and simulated competition (P

AbstractAim: This study aimed to investigate the effects of intense resistance exercise on IGF-1 system and monitoring time course of changes in its components.Method: Nineteen healthy physical education students as trained group (age 22.21±1.44 years, height 178.41±6.39 cm, weight 73.47±7.86 kg) and fifteen healthy nonphysical education students as untrained group (age 23.07±1.91 years, height 174.02±5.08 cm, weight 70.47±10.13 kg) volunteered to participate in this study and each group were randomly divided into two experimental and control groups. Experimental groups performed one session of resistance exercise with 70-80% 1RM. Blood sampling was done 4 times, 2-hours after breakfast (Pre-test), immediately (T2), 4- (T3) and 7-hours after the exercise (T4). Blood samples were analyzed by RIA method. Two-way repeated measure (ANOVA), Friedman and Kruskal-Walis tests were used to analyze data.Results: One session of resistance exercise was associated with a significant increase in GH at T2 (P
