| Summary: | Background and Study Aim. The aim of this study was to examine the acute responses to repeated sprints on a non-motorized treadmill on dominant leg (DL) and non-dominant leg (NDL) sprint parameters.
Material and Methods. Volunteered students from Sports Sciences Faculty were randomly divided into experimental group (EG) and control group (CG). As pre- and post-tests, each participant performed 30m sprint test on a non-motorized treadmill. There were 6x20m with 1min on a non-motorized treadmill as repetitive sprints. As a statistical analysis, whether there is pre-test and post-test differences were analysed with independent t test between the groups and paired t test within the groups. The level of significance was taken as p≤0.05.
Results. In comparisons within the groups, both groups had significant pre- and post-test differences in parameters of time (t), velocity (V), and power (P) [for EG, p<0.001, p<0.001, and p<0.001; for CG, p<0.001, p<0.001, and p<0.01, respectively]. CG had significant pre- and post-test differences in parameters of stride length (SL) and horizontal force (HF) (p<0.05). There were no statistically significant pre-test differences in 30m sprint parameters of NDL and DL. In post-tests, there were only significant differences in SLDL, HFDL, PNDL, and PDL (p<0.05, p<0.05, p<0.05, and p<0.01, respectively). CG had only significant pre- and post-test differences in SLNDL and SLDL within the group’s comparisons (p<0.05). Either EG or CG had significant pre- and post-test differences in PDL (p<0.05).
Conclusions. In conclusion, repeated sprints may exhibit shorter strides to overcome horizontal resistance and fatigue, resulting in reduced SL and greater P exerted in the DL. |
