All subjects were habituated to treadmill locomotion prior to exposure to three walking treatments (0.83, 1.39 and 1.94m.s⁻¹) and three running treatments (2.50, 3.06 and 3.61m.s⁻¹). During each of these five-minute locomotor conditions, energetic (V02), kinematic (cadence and stride length) and psychophysical (central and local RPE) data were captured. From these data, lines of best fit were calculated for each subject, allowing for a prediction of the abovementioned locomotor variables from known absolute rates of progression. Using suitable regression equations, subject responses to morphology-normalised speeds of walking and running were effectively extrapolated. When the rate of progression was expressed in absolute terms (m.s⁻¹), significant differences (P <0.05) were found between the stature-related groups with respect to both energetic and kinematic locomotor responses. Such differences were successfully eliminated when use was made of locomotor speeds relativised on the basis of morphology. This study concludes that the use of appropriately prescribed morphology-normalised rates of progression are effective in reducing the variability in locomotor responses between subjects differing significantly in stature.]]> Thu 13 May 2021 06:06:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:5142 Thu 13 May 2021 05:57:08 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:30153 0.2) results were found: (1) BMD (one or more rating and or Z-score) was positively influenced (had higher ratings) in runners who were overweight, consumed alcoholic beverages of five or less per week and who ran less than 51 km/week, respectively; (2) BMD (one or more rating and or Z-score) was negatively influenced (had lower ratings) in runners who had more full-term pregnancies and among those who were menopausal, respectively; (3) BF% and BMI were both found to be lower in runners who: were not menopausal, competed in six or more ultra-marathon events, completed marathons in less than or equal to three hours and 50 minutes, had an incidence of breaking a bone due to a traumatic event, and engaged in an average weekly running distance of more than 50 km/week, respectively.]]> Thu 13 May 2021 03:10:14 SAST ]]>
