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.

Arm && Interventions

Group	Intervention	Description
PAPE 90% warm up protocol	Experimental	performed three repetitions of dip squats with 90% of their one-repetition maximal dip squats and rested for 4 minutes.
PAPE 50% warm up protocol	Experimental	performed three repetitions of dip squats with 50% of their one-repetition maximal dip squats and rested for 4 minutes.
Unloaded warm-up protocol	unloaded protocol	They performed the snatch movement with 75% of their maximum snatch weight without pre-warm-up, i.e. without weights, until exhaustion.

Primary Outcome Measures

Name	Time	Method
number of snatch repetitions performed to exhaustion	Two weeks	This outcome is measured to determine how different warm-up protocols (90% 1RM squats, 50% 1RM squats, and no-load condition) affect the athletes\' performance in snatch repetitions. The statistical analysis focuses on comparing the average number of repetitions between these protocols.
