Abstract

This study aims to examine the effects of resistance versus complex exercise with the retention of post-activation potentiation (PAP) on vertical jump among volleyball players. A total of 30 volleyball players (mean age = 16.5 ± 1.106 years old) were recruited as participants of this study. The participants were requested to attend two different testing sessions, with two days between each session. Each session had a different exercise routine, namely, resistance and complex. A one-way repeated measure was used to analyse the performance of the vertical jump, while a pairwise comparison was applied to compare the retention of PAP between the resistance and complex exercises. The findings show that there is a significant interaction for both warm-up exercises; [(F(1,29)=1275.57, p=0.000] for resistance exercise and [(F(1,29) = 1456.83, p= 0.000] for complex exercise. The retention analysis for PAP effect also indicates that there is a significant difference between the two warm-up activities in vertical jump performance. In conclusion, this study reveals that both exercises managed to increase PAP among volleyball players. However, complex exercise is suggested to be combined with the warm-up method as it can maintain a longer retention than resistance exercise.

Highlights

Warm-up has become a common practice before any physical activity is performed (Wood et al, 2007) and its purpose is to prepare the body mentally and physically
The objective of this study is to determine that the warm-up activity with a single 6-RM set of the back squat is effective at inducing post-activation potentiation (PAP) and increasing the performance of Vertical jump test (VJ) and the duration of retention
The findings of this study were consistent with the previous research that complex exercise managed to improve effectiveness of the leg power when combined with warm-up activities (Carter et al, 2014) as compared to resistance exercise and the retention of PAP

Summary

Introduction

Warm-up has become a common practice before any physical activity is performed (Wood et al, 2007) and its purpose is to prepare the body mentally and physically. There are warm-up methods used to procure post-activation potentiation (PAP) effects. PAP refers to a neuromuscular phenomenon that tends to increase power after stimulation of the contractile. PAP effects may be difficult or less sustainable without resistance exercise through warm-up methods. Apart from that, the variable, e.g. the intensity of the exercise, could be one of the factors that affect PAP. According to Sale (2002) and Gilbert et al (2005), high-intensity exercise appears to be more effective on PAP. Despite this fact, there is still a lack of studies on the effect of PAP between resistance and complex exercises as a warm-up method on the performance of vertical jump in volleyball sports
