| Popis: | 106 Smart wearable sports devices are popular In recent years, and related running technologies can be controlled and monitoring by the three-axis accelerometers such as stride frequency (SF), foot stance time (FST), body vertical oscillation (vertical oscillation, VO) and other related factors. Therefore, the purpose of this study: Through three-axis accelerometer integrated in the GARMIN 920XT sports training watch, to investigate the SF, FST and VO and the maximum oxygen uptake running speed(vVO2max) correlations during the treadmill running test. Methods: recruiting professional runners (control group, VO2max:64.98±3.51ml/kg/min) and amateur runners (experimental group, VO2max:52.49±3.80ml/kg/min) to participate in this study, all subjects had to complete two times modified Bruce treadmill running tests. Personal had been record in the first trials for data normalized, and then 920XT had been attached on the chest of all subjects in the second trails, sprinting on the treadmill till to exhaustion to record the FST, VO and running time. One way ANCOVA statistic method was used to analyze the differences between groups and relationships among upon variances, significant level was set as α=.05. Results: professional runners had higher VO than amateur runners (mean ± SE: 99.95 ± 1.74, 92.51 ± 1.75, F = 9.109, p |
