简要总结
This study investigates the acute effects of Post-Activation Performance Enhancement (PAPE) on the number of repetitions performed to volitional failure and total training volume in resistance-trained men. The research is designed as a randomized crossover trial where participants perform two different exercise protocols under controlled conditions.
The study includes 9 healthy, strength-trained male volunteers aged 18-30 years, with at least one year of resistance training experience. Participants complete two experimental conditions:
PAPE Protocol: A warm-up followed by 3 repetitions at 90% of 1RM, a 10-minute rest, and then 3 sets of half-squat at 75% 1RM until volitional failure.
Control (CON) Protocol: A warm-up followed by 8 repetitions at 50% of 1RM, a 4-minute rest, and then 3 sets of half-squat at 75% 1RM until volitional failure.
The primary outcome measures are:
Total training volume (set × reps × weight) Number of repetitions performed The study aims to determine whether PAPE improves total volume and repetition performance in resistance training. The findings could contribute to better training strategies for athletes and fitness professionals.
Ethical approval was obtained from the Gaziantep University Clinical Research Ethics Committee (Decision No: 2022/373), and all participants provided informed consent before participation.
详细描述
This study explores the acute effects of Post-Activation Performance Enhancement (PAPE) on repetition performance and training volume during a half-squat exercise in resistance-trained men. PAPE is a physiological phenomenon in which performance is enhanced following a conditioning activity (CA) involving a high-intensity resistance exercise. The study focuses on its effect on resistance training (RT) performance, specifically the number of repetitions performed to volitional failure and the total training volume during a half-squat exercise.
Study Design The study follows a randomized crossover design. Each participant performs both experimental protocols: PAPE and Control (CON) conditions. A random assignment is used to ensure that each participant experiences both conditions in separate sessions, with a 72-hour rest period between them to allow full recovery.
Participants Total number of participants: 9 trained male university students, aged 18-30 years, with at least 1 year of resistance training experience.
Inclusion Criteria:
Male participants aged 18-30 years No musculoskeletal disorders or injuries in the previous 6 months At least 1 year of continuous resistance training, including use of the half-squat exercise

盲法说明
This is a single-blind study where the participants are unaware of which protocol (PAPE or Control) they are assigned to during each session. The investigators who administer the protocols and measure the outcomes are also aware of the assignment. The randomization process is done prior to each session to determine the order of protocols.

研究组 & 干预措施
PAPE Protocol
Participants in this group will first perform a warm-up consisting of 3 repetitions at 90% of their 1RM. After a 10-minute rest, they will perform 3 sets of half-squats at 75% of their 1RM until volitional failure.
干预措施: PAPE Protocol (Behavioral)
Control Protocol
Participants in this group will perform a warm-up consisting of 8 repetitions at 50% of their 1RM. After a 4-minute rest, they will perform 3 sets of half-squats at 75% of their 1RM until volitional failure.
干预措施: Control Protocol (Behavioral)
结局指标
主要结局
