Abstract
Introduction and purpose: warming up is one of the principles of training. Athletes have always attempted to achieve success and improve their performance during a competition or a training session. Therefore, proper warm-up before training and competition can help athletes to achieve their best performance. In modern training methods, before performing explosive activities, they perform resistance exercises that are biomechanically similar to skills. One of the methods is known as Post-Activation Potentiation (PAP). However, performing PAP usually requires special equipment. Therefore, coaches and trainers are looking to execute PAP using simple methods. Therefore, this research aims to compare the effect of traditional warm-up with two PAP protocols (plyometric with and without blood flow restriction) on some performance factors of volleyball players.
Materials and methods: The subjects of this research were 13 volleyball players with an age range of 21 to 26 years. Subjects performed one of the three warm-up protocols consisting of traditional warm-up protocol (TRD), plyometric exercises (PLY), and plyometric exercises with blood flow restriction (PLY+BFR) in 6 different sessions in a random cross-over manner. After four minutes of each protocol, the vertical jump and agility T-test was taken in the first three sessions and Wingate anaerobic test in the second three sessions.
Statistical methods of analysis of variance with repeated measurements and Bonferroni post hoc test were used to determine the presence of a significant difference (P<0.05).
Findings: A significant difference was observed in the explosive power, anaerobic power, and agility of the athletes between different warm-up protocols. The results showed that the PLY was able to show a greater improvement than other two protocols in the athletes' performance.
Conclusion: It is suggested to use plyometric exercise to improve the performance of explosive power, anaerobic power (average power), and agility of volleyball players before training or matches.
