    • Abstract:
      Introduction: The preferred transition speed (PTS) is an important parameter in gait research to distinguish the walking or running state. Most of the research on PTS, however, has been conducted with people of European and American ethnicities. Relatedly, previous studies exploring body measures as possible determinants of PTS were biased toward longitudinal body dimensions, and there have been few studies investigating the correlation between PTS and longitudinal and transverse parameters. Along those lines, there has been only limited research on PTS in Taiwan. The purpose of this study, therefore, was to use regression equations to determine the relationship between longitudinal and transverse anthropometric parameters and PTS in Taiwanese males. Methods: Longitudinal and transverse anthropometric parameters of the lower limb were measured in fifty-three Taiwanese males, and the walk-to-run and run-to-walk speed tests were performed to obtain the PTS of these subjects. The relationship between the PTS and the anthropometric variables was determined by using Pearson's product-moment correlations and stepwise multiple regression analysis. Results: Weak to small correlations between several body length and width variables and the PTS were found. Significant correlations (p < .05) between transverse body scaled to body height (pelvic width %) and the PTS were found (r = .275). The lower limb parameters were then subjected to stepwise multiple regression analysis. The results yielded a multivariate regression formula with PTS = .111 pelvic width (%) + 5.350 (R2 = .076). Conclusion: With the inherent differences in longitudinal body parameters (e.g., height, leg length (%), calf length (%)) between Taiwanese and European-American males, the results of the study suggest that it is not possible to estimate the PTS by referring to the regression results of foreign limb parameters. Therefore, the longitudinal and transverse anthropometric parameters of the lower limbs in Taiwanese males cannot be used as predictors of the PTS, suggesting that future studies on the relevance of other parameters, such as kinetics or kinematics, for the PTS should be conducted.
