Effects of explosive and impact exercises on gait parameters in elderly women

Abstract

Introduction: Several systematic reviews and meta-analyses have suggested that physical activity programs combining low impact exercises and resistance Objective: To analyze the effects of an aquatic training program involving both impact and explosive exercises on gait parameters of women aged 60 and above Materials and methods: 60 physically active women (64.08±3.98 years) were divided into 2 groups: those training in a pool by performing series of jumps, i.e., the experimental group (EG= 35), and the control group (CG=35). EG participants trained 3 times per week during 32 weeks in an hour per session basis. Body composition measurements, explosive strength, and gait parameters (in a 6 meters long track) were assessed using the center of pressure (COP) indicator before and after participating in the training program. Results: When comparing both groups, differences in explosive strength and power (EG vs. CG; p values=from 0.05 to 001) were observed, as well as changes in gait parameters related to the COP (EG vs. CG: p = 0.05-001), in particular EG participants had significant and positive changes. Conclusion: The aquatic training program described here produced an increase in muscle strength and muscle power, thus gait parameters were improved. Bearing this in mind, an improved availability of similar programs for older adults should be considered, since their participation in these programs could help them improve their functional capacity, and, thus, their quality of life.
