Effect of Regular Plyometric Training on Growthrelated Factors in Obesity Female Teenager

초록

OBJECTIVES This study aimed to investigate the effect of regular plyometric training on growth-related factors in obese female teenager. METHODS The subjects of the study consisted of elementary school students group (EG, n=5) and middle school students group(MG, n=6), and overweight or obese experimenters were selected based on the ‘2017 Child and Adolescent Growth Chart Age Body Mass’ index. Exercise was conducted for 12 weeks. All measurements were carried out before and after exercise. The data processing was verified using the SPSS 26.0 statistical program to verify the correlation between paired t-test and Pearson in the 12-week pretraining and post-training groups. RESULTS After 12 weeks of plyometric training, there were significant differences in height(p=.002), ASIS(p=.003), body fat percentage(p=.018), and muscle mass(p=.014) among body composition of EG. There was a significant difference in height(p=.015) in body composition of MG. In the evaluation of muscle function, in muscle strength(60°/sec), (R)-FLE PT/bw(p=.011), (L)-FLE PT/bw(p=.017) in EG and muscle power(180°/sec), (R)-FLE PT/bw(p=.024), (L)-EXT PT/bw(p=.001), (R)-FLE TW/bw(p=.004) and (L)-EXT TW/ bw(p=.012) showed a statistically significant difference. In terms of correlation, significant relationships were found between EG body fat mass and IGF-1(p<.05), and between body fat mass and IGF-1/IGF-BP3(p<.05). CONCLUSIONS Regular plyometric training had a positive effect on growth-related factors in obese female teenager.
