The purpose of the present research is studying the relations and differences between VO2max values and heart beat frequencies calculated with three different shuttle run tests used to determine the aerobic and anaerobic capacities of soccer players. Eleven amateur trained male soccer players (age = 23.18 ± 1.83 years, sport age = 11.82 ± 1.99 years) voluntarily participated in the present research. 20m Shuttle Run Test (20mSRT), Yo-Yo Intermittent Recovery Test level 1 (YYIRT1) and level 2 (YYIRT2) running tests, which are frequently used in VO2max. calculations, were performed by players on different days. Significant relations were found between heart rate frequencies and VO2max. values calculated after 20m SRT and YYIRT1, and YYIRT1 and YYIRT2 (respectively; r = 0,628, p
<0,05: r = 0,921, p
<0,01). No significant relations were found between 20mSRT and YYIRT2 (p
>0,05). There was no significant difference between heart rate averages after 20m SRT and YYIRT1 (p
> 0.05). There was a significant difference between the VO2max averages calculated according to 20m SRT, YYIRT1 and YYIRT2 levels (p
<0.01). Consequently, we can claim that occurred a similar workload on athlete’s because of the similarity between the athletes' heart rate averages after 20m SRT and YYIRT1. But there was no such similarity between VO2max values calculated from both test scores of the players. According to these findings, it is revealed that different energy sources are used in the performance of both tests. Higher heart rate averages and estimated VO2max values for YYIRT2's performance showed that the energy metabolism used was different for the other two tests and the workload intensity on the athlete was higher.Pages: 112-117 | 522 Views 25 DownloadsDownload Full Article:
