The mechanisms involved in youth are basically unknown. Although there are no effective therapeutic interventions to increase life expectancy and physical well-being, it seems that physical activity can play an important role in the physical and mental health of young people. Therefore, the purpose of this study is to investigate the impact Endurance and intense resistance training on epidemiologic growth factor and creatine phosphokinase induced muscle injury in young boys. In this study, 30 young boys with an average age of 16 years were placed in 3 groups of endurance and intense resistance training and control. The exercises were performed during 8 weeks with a frequency of 3 sessions per week. Endurance exercises with an intensity of 60-75% of the maximum heart rate and intense resistance exercises With an intensity of 75%, one repetition maximum (IRM) was performed, which reached 85% during the training weeks. Blood samples were collected 24 hours before the start of training and 48 hours after the last training session. Analysis and comparison between groups was done by analysis of covariance test and for intra-group comparison of data by T-test, paired at the significance level of P<0.05. The values of EGFR in two endurance groups P<0.006 and extreme resistance P<0.003 and CPK values in the extreme resistance group P=0.03 have a significant increase compared to the control group. But there was no difference in CPK values between two endurance and control groups, P=0.11. The increase of appropriate EGFR values has caused more appropriate regeneration in muscles in this age group.This research is applied and semi-experimental with two
experimentalgroups and one control group
Pre-test and post-test were conducted and the research sample was young boys with the age range of 17-15 years
formed. The statistical population of the research was formed by young boys with an average age of 16 years and in the gym
Takhti Urmia did recreational and non-continuous morning exercise, which was purposeful based on the inclusion criteria of the study, including non-smoking, absence of specific diseases that
Taking medicine was considered.
