Abstract

This study aimed to investigate the effects of acute and chronic pyramid and reverse PYRAMID RESISTANCE TRAINING on growth factor (IGF-1) and serum cell injury index (Creatine kinase) in non-athlete girls and also to assess the possible relationship between CK and IGF-1. Many studies investigated IGF-1 and CK changes separately, but considering growth factors secretions due to cell injury (cell injury hypothesis), this relationship is not clear yet. 27 subjects (age 18.5 ± 2.20 years, weight 56±9.86 kg, height 16.2±5.33 cm) participated in this study and were divided into 3 groups, pyramid (N=10), reverse pyramid (N=10) and control (N=7). Pyramid and reverse pyramid performed resistance training (arm curl, arm extension, lateral pull, leg extension, leg curl and leg press, each exercise contains 3 sets and 2 min rest between sets) 3 times a week for a total of 6 weeks. In pyramid group the first set was 10 repetition with 50% of 10 RM, the second 75% of 10RM, and the third 100% of 10RM, and in reverse pyramid group vice versa. Blood sampling was at the beginning and at the end of the first and the last session in order to analyze IGF-1 concentration via ELIZA method and CK via enzymatic method. Maximum strength measured at the end of week 3 and 6. ANOVA used to compare data in the groups and independent t test used to compare data between the groups. Maximum strength increased in both groups similarly, except for the biceps which was higher in reverse pyramid. Body composition didn’t change. After one session, IGF-1 level decreased but it was not significant, CK levels in both groups increased. After 6 weeks of resistance training, there was no change in response but CK increased in reverse pyramid There was no relationship between IGF-1 and CK. Considering the point that CK increase and there was no change in IGF-1, it seems cell injury can not activate growth factor response.
