Effects of upper body resistance training on muscle activation psychophysiology and shooting performance among compound archers

The aim of this study was to evaluate the effects of upper body resistance training on muscle activation, psychophysiology and shooting performance among compound archers. This study involves a pre and post experimental design with experimental groups and control group. Thirty compound archers (Mean age = 19.0 _ 2.3 years) completed the whole study protocol. All parameters were measured at pre-intervention and post- intervention. Electromyography was used to measure muscle activation. Heart rate monitor was used to measure the physiological variable. The revised Competitive State Anxiety-2 was used to measure competitive state anxiety and shooting performance was assessed through the total scores of double 50 meters round. The results of Mixed factorial analysis of variance revealed a significant interaction between the experimental group and control group (p < 0.05) after the intervention for anconeus muscle and self-confidence. The experimental group was found (p = .02 < .05) for muscle activation on anconeus muscle compared to control group during shooting. Furthermore, the experimental group was found (p = .02 < .05) for self- confidence compared to control group during shooting. After 12 weeks of intervention, the results shown a significant difference between athletes _characteristics including age (p = .02 < .05), weight (p = .04 < .05), sports performance (p = .003 < .05) and years of experience (p = .001
