A six-week upper- and lower-body PJT program improved physical fitness and anthropometric measures in recreationally active young men, regardless of whether an intra-set rest of 0, 10, 20, or 30 s is used. However, the inclusion of 20 or 30 s rest into the sets (i.e., the CLS20 and CLS30 configurations, respectively) reduced exercise-induced fatigue perception. Current findings provide novel and practical relevance to design optimal plyometric training protocols using the CLS or TRS configuration for the improvement of physical fitness and body composition, in line with reduced perceived fatigue, a key element for long-term physical activity habits.
