The Effect of Upper Limb Post-activation Potentiation on Increases in Vertical Jump Height Due to an Arm Swing
نویسندگان
چکیده
Post-activation potentiation (PAP) refers to the phenomenon where muscular performance is improved as a result of contractile history. The aim of this study was to investigate the effects of upper limb PAP on vertical jumping. Firstly, countermovement jumps were performed with (CMJAS) and without an arm swing (CMJ). Participants then carried out 10 dumbbell swings with a weight of 15% of the participant’s body weight and performed further countermovement jumps with an arm swing at 3 (PAP3mins), 6 (PAP6mins) and 9 (PAP9mins) minute rest periods. There was a significant difference (p < 0.05) in jump height, peak vertical GRF and peak concentric power when comparing CMJ to CMJAS. No significant difference was found when comparing a CMJAS to any of the conditions with induced PAP on the upper limbs. This indicates that inducing PAP on the upper limbs does not have a significant effect on jump height.

There is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. Due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. Therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...
