Brief Summary

This study investigated the acute effect of post-activation performance enhancement (PAPE) on snatch performance to exhaustion in elite weightlifters.

Detailed Description

Background This study investigated the acute effect of post-activation performance enhancement (PAPE) on snatch performance to exhaustion in elite weightlifters.

Methods The study was designed according to a randomized crossover experimental design. Twelve male elite athletes (age; 18.45 ± 0.52 years; height; 1.73 ± 0.03m, body mass; 71.36 ± 11.36kg) voluntarily participated in the study. The participants performed a general warm-up for five minutes, followed by a weightlifting-specific warm-up for five minutes, and rested for two minutes. Then, the athletes performed three different PAPE protocols on different days and performed the snatch performance to exhaustion. Shapiro-Wilk test was applied for the normality test, and the Levene test was applied for the homogeneity test. Repeated measures of two-way analysis of variance (2x3) were applied to analyze the differences between treatments. Greenhouse-Geiser correction test was used for measurements where the sphericity assumption was not met.

Study Groups

PAPE 90% warm up protocol

performed three repetitions of dip squats with 90% of their one-repetition maximal dip squats and rested for 4 minutes.

Group Type: EXPERIMENTAL

Experimental

Intervention Type: OTHER

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.

PAPE 50% warm up protocol

performed three repetitions of dip squats with 50% of their one-repetition maximal dip squats and rested for 4 minutes.

Group Type: EXPERIMENTAL

Experimental

Intervention Type: OTHER

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.

Unloaded warm-up protocol

They performed the snatch movement with 75% of their maximum snatch weight without pre-warm-up, i.e. without weights, until exhaustion.

Group Type: OTHER

unloaded protocol

Intervention Type: OTHER

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.

After rest, they performed the snatch movement with 75% of their maximum snatch weight until exhaustion.
