| Abstract: | Running is a simple physical activity promoting a consistently active and healthy way of life. It offers advantageous impacts on cardiovascular and respiratory fitness, weight management, and mental well-being. However, the high rate of discontinuation and running-related injuries are common problems among novice runners. Purpose: To compare the cardiorespiratory responses, kinematic changes, and psychological responses between Tachi Run and Moderate Intensity Constant Run. Methods: 21 novice runners participated. We performed four experiments for every subject. The first two tests tested subjects' abilities to develop a Taichi Run (TCR) and Moderate Intensity Constant Run (MICR) protocol. In the last two experiments, subjects performed TCR and MICR randomly. We compared the cardiorespiratory responses, kinematic changes, and psychological responses of TCR with that of MICR in novice runners to explore the running program for novice runners. Results: For the cardiorespiratory responses, we found that TCR could stimulate significantly higher Peak HR, maximum change of HR, Peak VO2, and maximum change of VO2 than MICR (P < .001). For the kinematic changes, there was no significant difference in the accumulated impulse throughout the run, step duration, step frequency, and normalized contact time between TCR and MICR (P > 0.05). However, the decrease in ankle dorsiflexion angle between 100m of pre-run walking and 100m of post-run walking was more significant in TCR than in MICR (P = 0.006). There was no significant difference in the Rating of Perceived Exertion (RPE) and the Physical Activity Enjoyment Scale (PACES) (P > 0.05) between TCR and MICR. Conclusion: In light of the internal responses and external responses, Taichi Run was proposed as a running program suitable for novice runners due to its optimal level of exertion and its ability to engage the skeletal, muscular, respiratory, and cardiovascular systems. |
