About this study
Official title: Effect of Post-Activation Potentiation Effect on Snatch Performance to Exhaustion in Elite Weightlifters
This study investigated the acute effect of post-activation performance enhancement (PAPE) on snatch performance to exhaustion in elite weightlifters.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ExperimentalOther
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.
ExperimentalOther
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 protocolOther
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Other: Experimental |
| 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. Receives: Other: Experimental |
| Unloaded warm-up protocol | Other | They performed the snatch movement with 75% of their maximum snatch weight without pre-warm-up, i.e. without weights, until exhaustion. Receives: Other: unloaded protocol |
What is being measured
The primary outcome is the main question the study is designed to answer.
number of snatch repetitions performed to exhaustion
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.
Measured: Two weeks
