Title : Effect of squat exercise on muscle oxygenation in inactive obese elderly individuals with geographical disparity. A perspective case series study
Abstract:
Background: For the increasing number of obese older adults away from the city center, physical activity appears to be a safe way to promote and maintain weight loss. Given this background, the aim of this study was to assess the effect of squat exercise on body composition and muscle oxygenation in overweight and obese older adults, with a focus on sarcopenia.
Methods: A perspective case series study was conducted by performing squat exercises 3 days per week for 24 weeks in overweight and obese individuals. Body composition markers such as skeletal muscle index (SMI), fat mass, and lean mass of arms and legs were measured by dual energy X-ray densitometry (DXA) at baseline and 24 weeks post-exercise. For measuring SmO2 Train.Red sensor was placed on the participant's dominant leg, specifically targeting the VL and BF.
Results: Nine subjects (male/female 6/3, mean age 68.22 ± 3.86 years, BMI 32.34 ± 4.89 kg/m2 ) were evaluated. We noted a median decrease in BMI (-0.88 kg/m2 ), weight (-2000 g), fat mass (-1498 g), and an increase in SMI (+0.04 kg/m2 ) from baseline. Oxygenation in VF- BF also improved, with a median change in SmO? of +0.80%. Conclusions:Twenty-four weeks of squat exercise was associated with reductions in fat mass. It was also found to increase muscle oxygenation and blood flow.
