Mini-trampoline Intervention vs. Nordic Walking: Balance, Fitness and Neuropsychological Effects (TraWaFit)

Comparison of 12-week Mini-trampoline Intervention With a Nordic Walking Intervention: Balance, Fitness and Neuropsychological Effects

The effects of mini-trampoline training on balance, cardiorespiratory fitness, strength and neuropsychological parameters in an overweight or obese population are unknown. The aim of this 2-arm randomized controlled trial is to compare the effects of a 12-week mini-trampoline training and a 12-week nordic walking training on balance, fitness and strength in overweight/obese individuals.

Study Overview

• Status: Completed
• Conditions: Obesity; Overweight
• Intervention / Treatment: Other: mini-trampoline; Other: Nordic Walking

Detailed Description

A growing body of literature suggests, that obesity is not only associated with medical conditions such as diabetes, but also linked to altered gait, impaired balance and a greater likelihood of falls. Weight reduction has been shown to improve balance controle. Methods to increase physical activity are largely not accepted in this population and those which conserve the musculoskeletal system are rare. Physical activity has been shown to influence mood, quality of life and eating behavior. Mini-trampoline training has been shown to enhance stability and increase fitness.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Mini-trampoline; participants allocated to this group will participate in a 12-week mini-trampoline group instructed training twice a week.	Other: mini-trampoline; Intervention period lasts 12 weeks, training is group instructed, twice weekly. Training sessions are one hour each. The training intensity of the two interventional arms is comparable. The training progression is defined in advance.
Active Comparator: Nordic Walking; participants allocated to this group will participate in a 12-week Nordic Walking group instructed training twice a week.	Other: Nordic Walking; Intervention period lasts 12 weeks, training is group instructed, twice weekly. Training sessions are one hour each. The training intensity of the two interventional arms is comparable. The training progression is defined in advance.
