The Post-Activation Potentiation (PAP) is a strategy to improve performance, using a fixed load (RF), defined at the sticking point (PFM). Moreover, the use of chains (CRT) is an effort with variable resistance (RV). Thus, the objective was to evaluate the effects of CRT in the countermovement jump (CMJ). With an intervention study, 15 subjects were evaluated for the maximum squat load (1RM) and height in CMJ. After that, they performed three types of interventions: i) RF with 85% of 1RM; ii) RV with 85% of 1RM positioned in PFM (RV-TF), and iii) RV at 85% of 1RM positioned at greater knee extension (RV-TV). It was observed increase in CMJ to RV-TF and RV-TV, but not to RF. It is concluded that there was PPA with the two RV stimulus.
