Abstract :

The aim of the present study is to determine the effect of 12 weeks of bodyweight training on neurotrophic factors in children with hypotonic cerebral palsy. 20 children with hypotonic cerebral palsy with an average age of 8 to 12 years were selected and placed in two groups of body weight training (n=10) and control group (n=10). Subjects of the Bodyweight group performed exercises that included basic strength, maximum strength and high-intensity interval training for 12 weeks and three sessions a week. The training intensity was 25% 1RM in the first to third week, 50% in the fourth to sixth week, 75% in the seventh to ninth week, and 100% in the tenth to twelfth week. Blood samples were taken 24 hours before and 24 hours after the last training session. To analyze the data, independent t-tests were used to survey the inter-group difference and correlated t-test to survey the intra-group difference at a significant level (P<0.05). The results of data analysis showed a significant increase in the levels of neurotrophin factors (BDNF, NGF, IGF-1) in the body weight training group. Due to their structure, Bodyweight exercises can be easily used by children with hypotonic cerebral palsy. It seems that these exercises improve the skeletal muscle tissue in these children by increasing the levels of neurotrophic factors, and by slowing down the atrophy process and reducing the muscle tissue, it improves their movement and posture disorders and balance problems. .
