Post Activation Potentiation
Some research on post activation potentiation and force rate relationship have mostly involved isometric contraction, type of muscle contraction affects rate of frequency and force frequency over which post activation potentiation happens. In concentric muscle contraction (CMC), especially at high velocity the force frequency relation is transferred to the right compared to the isometric muscle contraction (IMC), this is because high frequency is needed to induce a desired percentage of maximum force Abbate, et al., (2000). PAP still plays a major role to high frequency in concentric vs isometric contraction for example Rowling, swimming and cycling involve concentric movement and concentric-eccentric contraction can be weightlifting, running
