Abstract

A warm-up helps the individuals to prepare themselves for strenuous workouts. The warm-up is generally executed before participation in any physical activity or sports. The objective of the study was to investigate the effects of sequencing lower-body static and dynamic stretching combinations on agility, speed, and leg power of school-level female Netball players. Three different stretching protocols were performed: (a) Static Stretching combined with Dynamic Stretching (SS+DS), (b) Dynamic Stretching combined with Static Stretching (DS+SS), and (c) Dynamic Stretching combined with Dynamic Stretching (DS+DS). A control warm-up condition without stretching was implemented with a prior aerobic warm-up followed by dynamic activities. Dependent variables included a 30-m Sprint, Agility run, and jump tests to measure speed, agility, and leg power performance. The level of significance was set at 5% for statistical analysis. The method used for statistical analysis was two-way ANOVA. There was no significant impact of stretching protocols on agility (p=0.257), speed (p=0.106), and leg power (p=0.902) of school-level female netball athletes. The results of the analysis allow the authors to retain the hypothesis that a sequence of static and dynamic stretching combinations does not significantly affect the agility, speed, and leg power of school-level female netball athletes.

Highlights

1 Warming up sessions commonly consist of activities such as slow jogging, cycling, swimming and stretching (Ab Malik, 2018)
The objective of the study was to investigate the effects of sequencing lower-body static and dynamic stretching combinations on agility, speed, and leg power of school-level female Netball players
No significant interactions were found between order and protocol for all agility, speed and leg power performance of the participants (p>0.05)

Summary

Introduction

Warm-up is generally promoted as an activity that enhances athletes’ performance. It is especially important in team sports demanding acceleration, deceleration, or direction changes ( Pojskic , et al, 2015). Stretching has been a main element of the pre-event warm-up. Pre-event static stretching has been prescribed to prevent injury by increasing the range of motion about a joint or series of joints and improving dynamic activities. Dynamic stretching has recently been prescribed by strength and conditioning professionals for pre-event stretching. This increase in prescription is due to recent evidence suggesting that pre-event static stretching negatively affects performance measures, such as strength, jumping, and sprint performance. A dynamic warm-up has been shown to improve knee joint position sense, increase oxygen uptake, lower lactate concentration, raise blood pH, improve the efficiency of thermoregulation, and improve performance for bicycle sprints and vertical jumps (Macmillian, Moore, Hatler, & Taylor, 2006)
