PURPOSE: To examine the effects of a training program based on impact and explosive movements performed in swimming pools on body composition (Total body weight, Body Mass Index-BMI, waist Hip Index-WHI, Fat Mass, lean mass), explosive strength (squat jump-SJ, counter movement jump-CMJ, counter movement jump arm swing-CMJas), and gait parameters (centre of pressure-COP, longitudinal displacement-LD) in women over 60 years METHODS: seventy healthy and physically active old women (60 ± 4.19) was divided into a training group based on multi-jumps performed in a swimming pool (“n=35, GE”) and a control group (“n=35, CG”). GE trained three times a week, an hour and a half per session and for a period of 32 weeks. Tests of body composition, explosive strength and gait parameters were applied before and after the training program RESULTS: There were significant differences in body weight (GE=+2% vs CG=-1%; p=0, 013), BMI (GE=-1,6% vs. CG=-1%, p=0,023) and WHI (GE=-1,6% vs CG=1%; p=0, 042) between GE vs CG. Differences in SJ, CMJ, CMJas height (jump height), flight time and Take off velocity and gait parameters (Centre of pressure, p=0, 033) were found between GE vs CG (JG vs CG = (p≤0, 05 and 0,001), with positive changes for GE CONCLUSIONS: The results suggest that 32 weeks of training with explosive and impact movements in swimming pools improve the strength expressions and induces significant adaptations in gait parameters, but not enough to alter body composition
