The purpose of this study was to examine the acute effect of different stretching protocols on flexibility, Yo-Yo IR-1 and repeated sprint performance. The sample group of this study consists of 15 male who were doing regular exercise at least 3 years. This group performed 5 different stretching protocols on non-consecutive days. Stretching protocols were determined as follows: light jogging for only 5 minutes (NS), light jogging and static strectching (SS), light jogging and dynamic stretching (DS), light jogging and static + dynamic stretching (SDS), light jogging and dynamic + static stretching (DSS). Altough participants did not have a statistically significant effect on flexibility performance (p> 0.05), the best flexibility value was SS. Repeated sprint performance (best) values of different stretching protocols did not have statistically significant effect on repeated sprint performance (moderate, worst, decline, post fatigue index) values (p> 0.05). Repeated sprint performance was found to have a statistically significant effect on Borg values and HR mean values (p <0.05). It was found that Yo-Yo IR-1 has a statistically significant effect on BORG values, Yo-Yo IR-1 performance HR (pre) values, Yo-Yo IR-1 performance HR (middle) values and Yo-Yo IR-1 performance lactate values (p<0.05). According to the findings obtained as a result of the research; it has been observed that different stretching protocols have different effects in terms of repeated sprint, flexibility and Yo-Yo IR-1 performance parameters. Overall, these results suggest that flexibility performance may be improve after static stretching exercise.
Objective: In this study, it was aimed to investigate the acute effects of different stretching exercise protocols on some anaerobic motoric tests. Material and Methods: The sample group of this study consists of 15 male (age: 21.8±1.4 years, stature: 1.77±0.32 m, body mass: 69.1±6.7 kg, body mass index (BMI) 21.9±2.0 kg/m 2 , body fat ratio (BFR) 10.9±4.0 %) volunteers who were engaged in regular exercise for at least three years. Volunteers performed five different stretching exercise protocols on non-consecutive days. Stretching exercise protocols were determined as follows: light jogging for only 5 mins (NS), light jogging and static stretching exercise (SS), light jogging and dynamic stretching exercise (DS), light jogging and static stretching exercise + dynamic stretching exercise (SDS), light jogging and dynamic stretching exercise + static stretching exercise (DSS). "Repeated measures ANOVA" test was used to determine the effect of different stretching exercise protocols on vertical jumping, agility, anaerobic power, mean power and linear running scores. Results: Different stretching protocols did not make a statistically significant effect on vertical jumping, anaerobic power, mean power and agility test results (p>0.05). Participants' linear running test results for 10, 20 and 30 m revealed significant differences with respect to stretching protocols (respectively p<0.001, p<0.001 ve p<0.01). Conclusion: The results of this study revealed that linear running performance figures were observed to be highest after dynamic stretching exercise. Dynamic stretching exercise protocols are recommended to trainers and athletes in order to reach better performance in 10m, 20m and 30m sprints.
