Effect of Post-Activation Potentiation

In the PAPE 90% protocol, participants performed a general warm-up (e.g., jogging on a treadmill) for 5 minutes and a weightlifting-specific warm-up for 5 minutes, followed by 2 minutes of rest. After resting, they were asked to perform ten repetitions of dip squats with body weight and rested for 1 minute.Then, unlike the unloaded protocol, they performed three repetitions of dip squats with 90% of their one-repetition maximal dip squats and rested for 4 minutes. After resting, they performed a snatch to exhaustion with 75% of their maximum snatch weight. Then they rested for 2 minutes and performed one more repetition of the snatch to exhaustion. The maximum number of repetitions between sets was recorded.

In the PAPE 50% protocol, 5 minutes of general warm-up (jogging on a treadmill) and 5 minutes of weightlifting-specific warm-up were followed by 2 minutes of rest as in the other protocols. After resting, they were asked to perform ten repetitions of body-weighted dip squats and rested for 1 minute. Then, unlike the unloaded and PAPE 90% protocols, they performed eight repetitions of bottom squats with 50% of their maximal bottom squats for one repetition and rested for 4 minutes. After resting, they performed snatches with 75% of their maximum snatch weight until exhaustion. Then they rested for 2 minutes and performed one more repetition of the snatch to exhaustion. The maximum number of repetitions was recorded for statistical analysis.

In the unloaded protocol, subjects performed a 5-minute general warm-up (e.g., jogging on a treadmill) and 5 minutes of weightlifting-specific warm-up followed by 2 minutes of rest. After resting, they performed ten repetitions of bottom squats with their body weight and then rested for 1 minute. After rest, they performed the snatch movement with 75% of their maximum snatch weight until exhaustion. Then, they rested for 2 minutes and again performed the snatch with 75% of their maximum snatch weight until exhaustion. The maximum number of snatch repetitions performed by the weightlifters was recorded for statistical analysis.
