Team sports activities had been found to improve non-athletes physical performance. However, lack of studies reported on individual games. This present study aimed to determine whether isometric contraction of arm during archery intervention respond better to upper and lower body muscles strength and grip strength. Total thirty-four sedentary men had involved; seventeen performed 12 weeks (3x week-1) of archery intervention (AG) and seventeen maintain as sedentary behaviour (SG). Upper and lower body muscles strength were determine at pre and post training, and detraining by isometric contraction test using hand-held dynamometer. Meanwhile, hand grip strength was assessed using JAMAR hand grip dynamometer. The data were analysed using ANOVA repeated measures. Pre intervention muscles and grip strength were similar between groups and increase significantly in archery group (p < 0.05). There was a significant group x time and group x intervention interaction in strength especially upper body and grip strength. Pairwise imposed that archery group improved strength between 17% and 46% compared to baseline, whilst control group varies between - 4% and 6% of changes. After detraining of 12 weeks, the muscle strength of intervention group regressed. The present study offers novel but provisional data that lower body strength adaptation is lesser despite comparable adaptation to upper body strength. © 2020 by SCITEPRESS - Science and Technology Publications, Lda.
