Combined and comparative effects of plyometrics and dynamic stretching on vertical jump in volleyball players

Objective: Aim of this study was to investigate the combined and comparative training outcomes of plyometrics and dynamic stretching of lower limb muscle groups on vertical jump performance in male and female collegiate volleyball players. Materials and Methods: The study was carried out as two training sessions in a week, for eight weeks duration. The total number of participants was 90 male and 90 female collegiate volleyball players aged 18-22 years. All the participants were recreational players and they were playing one hour daily in the evening. They were randomly distributed into three male groups (Group 1, Group 2 & Group 3) and three female groups (Group 4, Group 5 & Group 6) with 30 participants in each group. All the participants underwent Sargent vertical jump performance test before starting the training session it was repeated in every two weeks of training program. Results: Plyometrics and plyometrics with dynamic stretching led to significant improvements in vertical jump height (VJH), and this improvement was progressed after every two weeks of training. However, the control groups did not display any improvement. The effect of training was significantly higher in male and female groups who have performed plyometrics with lower limbs dynamic stretching as compared with the groups that performed only plyometric exercises (p<0.05). Compared to females, male participants had a better improvement of VJH in both training groups (p<0.05). Conclusion: It can be concluded that two sessions of plyometric exercise training per week for eight weeks can improve the ability of VJH in male and female collegiate volleyball players. However, combined training of lower body plyometrics and lower limbs dynamic stretching had better results in terms of vertical jump performance.

Acute Effects of Static and Dynamic Stretching on Jump Performance of Volleyball Players

The aim of this study is to examine the acute effects of different stretching methods on jump performance of volleyball players. 11 female volleyball players (age: 24.36 ± 5.10 years; height: 177.81 ± 7.30 cm; weight: 68.17 ± 11.69 kg; body mass index (BMI): 21.46 ± 2.56 kg.m-2; sports age: 12.72 ± 5.31 years) have participated voluntarily in this study. The players have applied three different stretching protocols such as control (no stretching), static and dynamic stretching on non-consecutive days. The protocols have included 5 minutes general warm-up, 1 minute rest, 30-second stretch program for each muscle group (control group not included), 1 minute rest and countermovement jump (CMJ), squat jump (SJ) and standing long jump (SLJ) tests. Friedman analysis has been used for data analysis. Wilcoxon Signed Rank Test has been implemented in order to determine the difference among groups. At the end of the study, a significant difference has been found between control and dynamic stretching groups with regard to static stretching groups in view of CMJ and SJ performance findings (p <0.05). It has been found that there is a statistically significant difference in the test averages of dynamic stretching group compared to static stretching group in view of SLJ performance findings (p <0.05). This study shows that static stretching practices reduce the jumping performance of the players. As a result, it can be suggested that trainers should use dynamic stretching methods before the trainings on jumping properties containing explosive movements.

TO STUDY THE IMMEDIATE EFFECTS OF DYNAMIC STRETCHING V/S DYNAMIC STRETCHING AND KINESIO TAPING IN MARATHON RUNNERS WITH SHIN SPLINTS: A COMPARATIVE STUDY

Background: The number of people is now becoming extremely health conscious hence taking up activities like marathons, sprinting and other forms of exercises to full recreational and tness needs. With an increasing number of sprinters chances of developing shin splints become higher. Warm ups, stretching and kinesio taping are great preventive measures and treatment protocols. Methodology: Group A received dynamic stretching and group B received dynamic stretching and kinesio taping. Outcome measures were time taken in seconds and pain intensity using Numerical Pain Rating Scale (NRS). Conclusion: Dynamic stretching along with Kinesio taping resulted in greater improvement in the 30-meter running time as compared to just dynamic stretching.

Protecting the Body

This chapter introduces injury preventive practices for the music student. These include key activities such as warming up, cooling down, exercising, and participating in mind–body practices. The differences between static and dynamic stretching, as well as when to practice each methodology, are discussed. Ideas for cultivating healthful habits, both within students’ musical practice and in their daily life, are provided. The chapter includes descriptions of mind–body practices common among musicians, such as the Alexander technique and Feldenkrais. An injury-prevention toolkit at the end of the chapter provides several practical worksheets and exercises (available on the companion website) for music instructors to use with their students.
