Study Overview
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.

Masking Description
Weightlifters were randomly divided into three groups (A, B, C) of four people. Throughout the study, all groups practiced each warm-up protocol sequentially on different days.

Arms & Interventions
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.
Intervention: Experimental (Other)
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.
Intervention: Experimental (Other)
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.
Intervention: unloaded protocol (Other)
Outcomes
Primary Outcomes
number of snatch repetitions performed to exhaustion
Time Frame: 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.
Secondary Outcomes
No secondary outcomes reported
