Local and global effect of sub-maximal squat on post-activation enhancement of muscle power output

Title: Local and global effect of sub-maximal squat on post-activation enhancement of muscle power output. Objectives: The aim of this thesis is to determine whether the phenomenon of post-activation performance enhancement (PAPE) manifests locally or globally in terms of improved muscle power output. That is, to determine whether activation of a complex muscle chain will lead to improvements in the muscle power output of other muscle groups and muscle groups included in the activated muscle chain. In this way, to indicate the relationship between global and local physiological mechanisms causing PAPE. Methods: The quasi-experimental method and the method of analysis were used in this work. Eleven basketball players aged 18-28 years completed two measurements in random order. The measurements started with a non-specific warm-up followed by a pre- activation test (pre-CA) to obtain baseline values. Next, the players performed a specific warm-up and activation exercise (CA) in the form of a squat with an intensity of 2 × 4 × 90 % of one repetition maximum (OM) with a rest interval of 3 min. After the activation exercise, post-CA values were measured at minutes 5, 8 and 11 on force plates and at minutes 6, 9 and 12 on an isokinetic dynamometer (IKD). Pre-CA and post-CA test of the protocol one..
