Effect of 24-week repeated short-time walking based training program on physical fitness of black Cameroonian obese women
Résumé
This study aimed to examine the effects of a training program based on repetition of short-time walk sequences on cardiorespiratory response, physical performance and metabolic parameters in black Cameroonian obese women. One hundred thirty-nine obese women (body mass index [BMI]>30 kg/m(2)) were divided into three groups: premenopausal (Pre-M; 39.7 +/- 7.9 yr; n=48), postmenopausal (Post-M; 55.0 +/- 2.5 yr; n=61) and control group (CONT; 48.7 +/- 9.4 yr; n=30). Only Pre-M and Post-M completed 24-week repeated short-time walking program. Anthropometric, cardiorespiratory, metabolic parameters, and the 6-min walk distance (6MWD) were measured at baseline (S1), 12 weeks follow-up (S2), and 2 days after the last session (S3). Significant changes were observed in weight, BMI, fatty mass and 6MWD in Pre-M and Post-M after 24 weeks. The waist and hip circumferences, percentages of water, muscle mass and bone mass changed in Post-M. Total cholesterol, triglycerides, low density lipoprotein and forced expiratory volumes in 1 and 6 sec showed significant improvements in Pre-M and Post-M. High density lipoprotein increased only in Post-M (0.5 +/- 0.2 g/L vs 0.7 +/- 0.1 g/L, P=0.041). In conclusion, this training modality could constitute an option for obese women rehabilitation.
