Abstract
The purpose of this study was to identify the effects of warm-up strategies on countermovement jump performance. Twenty-nine male college football players (age: 19.4 ± 1.1 years; body height: 179.0 ± 5.1 cm; body mass: 73.1 ± 8.0 kg; % body fat: 11.1 ± 2.7) from the Tuzla University underwent a control (no warm-up) and different warm-up conditions: 1. general warm-up; 2. general warm-up with dynamic stretching; 3. general warm-up, dynamic stretching and passive stretching; 4. passive static stretching; 5. passive static stretching and general warm-up; and, 6. passive static stretching, general warm-up and dynamic stretching. Countermovement jump performance was measured after each intervention or control. Results from one way repeated measures ANOVA revealed a significant difference on warm-up strategies at F (4.07, 113.86) = 69.56, p < 0.001, eta squared = 0.72. Bonferonni post hoc revealed that a general warm-up and a general warm-up with dynamic stretching posted the greatest gains among all interventions. On the other hand, no warm-up and passive static stretching displayed the least results in countermovement jump performance. In conclusion, countermovement jump performance preceded by a general warm-up or a general warm-up with dynamic stretching posted superior gains in countermovement jump performance.
Highlights
Team sports, like basketball, soccer, handball and American football consist of high intensive movements that include sprints, jumps, intermittent movement direction and speed changes with many acceleration and deceleration motions
The purpose of this study was to investigate the effect of various warm-up protocols on countermovement jump performance
Results revealed that performance of general warm-up (GW) and GW-dynamic active stretching (DS) posted superior gains in Countermovement Jump Performance (CMJ) scores than other warm-up protocols examined in the study
Summary
Like basketball, soccer, handball and American football consist of high intensive movements that include sprints, jumps, intermittent movement direction and speed changes with many acceleration and deceleration motions. These kinds of activities require proper body preparation in order to enable athletes to show their full physical potential, correspondingly to have as best as possible sport performance from the very beginning of a competition. A typical warm-up consists of aerobic activity (jogging, cycling, rope jumping etc.) followed by different kinds of stretching exercises (passive/active static stretching, or dynamic active stretching), but some use specific sport exercises or a combination of all above mentioned (Samson et al, 2012; Chaouachi et al, 2010; Vetter, 2007; Fletcher and Jones, 2004; Knudson et al, 2001). On the other hand static stretching utilizes the assistance of an external
