| Description: | This cross-sectional experimental study compares energy expenditure (EE) during walking among UKM athletes and non-athletes in both genders at two speeds of walking (4.6 and 5.4km.h-1). This study also examines the effectiveness of physical characteristics (height, leg length, height to leg length ratio and resting heart rate) and gait parameters (step width, stride length and frequency) on EE during walking. A total of 191 healthy students from UKM (95 athletes; 48M and 47F, and 96 nonathletes; 48M and 48F) purposively took part in this study. A questionnaire was used to acquire information on the subjects' medical history and athletic background. Energy expenditure for eight minutes treadmill walking at different target speeds were measured using HR-V O2 conversion process technique. The descriptive analysis showed that the EE during walking at speeds of 4.6km.h-1 was lower in female athletes (2.95±.54) than the EE of male athletes (4.13±1), male non-athletes (3.84±.9) and female non-athletes (3.78±1kcal.min-1). The EE during walking at speed of 5.4km.h-1 in athletes (4.20±1 in males and 3.94±.72 in females) was lower than EE of walking in non-athletes (4.64±1 in males and 4.89±.1kcal.min-1 in females). All groups expended significantly (p<0.01) higher energy at the second speed except male athletes. A two-way ANOVA indicated that the interaction effect between athletic background and gender during walking at speed of 4.6km.h-1 was statistically significant, F (1, 187) = 18.99, p<0.001. Results also indicates that athletic background significantly improved EE of walking at speed of 5.4km.h-1 in both males and females, F (1, 187) = 23.12, p<0.001. However, there was no interaction between athletic background and gender, F (1, 187) = 3.099; p=0.08. Multiple regressions analysis revealed that there is a significant relationship (p<0.5) between EE of walking and leg length, height to leg length ratio, resting heart rate and stride frequency which might influence the EE of walking as the speed increased. The findings further reflected that athletic background and regular exercise could influence the efficiency of walking. The study also suggests that estimating EE of walking plays an important role in the information processing in total energy requirement that progressively and slowly effect weight management and health. It is also inferred that estimation of EE of walking needs to be explored further based on individuals' physical characteristics and physical activity level as well as weight and walking speed.,PhD |
