RESUMO

Health World Organization considers obesity as a world epidemic affecting all social classes and age ranges, increasing financial expenditures with public health. Physical exercises are important for health improvement and maintenance, since they provide significant physiological changes. Obese people participation in exercises is difficult due to their own appearance rejection, displacement difficulties, articular problems provoked by weight excess and thermal stress. The aquatic exercise Deep Water Running (DWR) can be suitable for this kind of situation. Performing it in a deep swimming pool, practiser uses a floater attached to the waist, allowing body to be safely submerged to the shoulders line, to carry out running movement in the water, with no impact. This activity reduces body exposure and injuries on lower members risks. This study checked DWR practice effects in a 17-weeks intervention, with no food restriction, with three weekly sessions of 52 minutes each, on body composition (weight, fat percentage and circumferences), physical fitness (cardio-respiratory condition, flexibility and strength) and quality of life (QOL) in 31 women, being 38 to 57 years old (average of 47.93 ± 5.46) and presenting 30 to 40% of body fat, in a single group experimental study, with initial and final assessments. At analytical level, to study differences from paired samples, Student t test and Wilcoxon non-parametric test were used for variable with no probability normal distribution; for association between interest variables Spearman coefficient was adopted and canonic correlation. Significance 5%-level was adopted. Results significantly indicated improvement on 17 of 24 variables, as follows: body fat reduction (Pollock Protocol) ? (p<0,01); arms and thighs circumference increase (p<0,001); cardio-respiratory condition (Wilder Protocol; Brenann) ? (p<0,005) and flexibility enhancement (Wells Bank) ? (p<0,01); thoracolumbar strength (p<0,001) and left and right hand prehension gain (p<0,05). QOL, assessed through WHOQOL-Abbreviates questionnaire showed a significant improvement of physical, psychological and social relations (p?0,05). Spearman coefficient points out a statistical significance between: age and thoracolumbar strength (p<0,05); pacing and right thigh circumference (p<0,05). Canonic correlation indicates a association between WHOQOL-Abbreviated and physical performance indicators (p<0,01), standing out: psychological, social and environment fields, age, fat percentage, thoracolumbar strength and right thigh circumference. Before such findings, we can conclude that DWR provided with favoring changes on physical fitness; values obtained do not depend on age or cardio-respiratory condition improvement, and QOL
