Acute effect of different stretching protocols on flexibility, yoyo IR-1 and repeated sprint ability performance

Abstract

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.

Education of the Lower Body Flexibility in Students by Combining Various Types of Stretching during Physical Education Lessons

“…The stretching types and their combinations used during warm-up were verified by Kafkas et al (2019). They tested a group of 15 men that were regularly involved in physical activities: jogging + NS, jogging + SS, jogging + DS, jogging + SS+DS, jogging + DS + SS, with a duration of 5 minutes.…”

Investigation of maximal strength performance in terms of training time routine

“…The results of the anthropometric measurements for the participants are presented in Table 1, which displays the mean and standard deviation for each group. Participants were given instructions to refrain from engaging in different types of exercises on the day preceding the measurements, to avoid consuming stimulating beverages such as tea, coffee, alcohol, and carbonated drinks, and to have their last meal at least 2 hours before the measurements were conducted, following the guidelines outlined by Kafkas et al [23].…”

“…Prior to the 1-RM test, all participants engaged [23]. Participants were given the autonomy to select their initial weights for the 1-RM test according to their personal preference.…”

“…The test concluded once participants indicated their inability to lift any more weight. All test results were documented in kilograms, in accordance with the procedures described by Kafkas et al [23]. Each group conducted the 1-RM test on a separate day and at varying time intervals, with there being a 72-hour gap between each session.…”

role of gender and training age in shaping physical characteristics of volleyball players

“…Matthys et al (2013) found that top young handball players outperformed non-elite players on speed tests. Kafkas et al (2019) reported considerable progress in the 30 m sprint with additional days of training. As he assessed the yearly growth of biomotor features in collegiate volleyball players during a two-year training and competition cycle.…”
