About this trial
The aim of this study will be to compare the effects of Xbox Kinect Sports (XKS) with respect to Nintendo Switch Sports (NSS) and the inactive control group (CG) on body composition (percent body fat and fat-free mass) and physical performance (hand grip strength, HGS; 30 seconds standing in a chair, timed get up and walk, TUG; sit and reach and 2-minute step test) in physically inactive older women. This study will be randomized controlled trial with three parallel groups: XKS (n= 13), NSS (n= 14) and CG (n= 16).

Those female who have musculoskeletal injuries or who are undergoing physical rehabilitation treatment that prevents their normal physical performance.
Those who have permanent or temporary contraindications to perform physical activity.
Trial design

Treatments tested in this trial
Physical activity
Other interventionThe complexity of the games will increase as the levels of the sports games advance, which leads to faster movements with greater demands to progress in the sequence of the games, which allows reaching increases in intensity.

Trial outcomes
Primary outcomes
Change from Fat-free mass at 12 weeks
This variable is obtained by body composition (bioimpedance), using eight-electrode tetrapolar bioimpedance (InBody 570®, Body Composition Analyzers, South Korea). For each measurement, the guidelines of the International Society for Advances in Kinanthropometry will be followed (Marfell-Jones et al., 2012).
Change from Body fat percentage at 12 weeks
This variable will be obtained by body composition (bioimpedance), using eight-electrode tetrapolar bioimpedance (InBody 570®, Body Composition Analyzers, South Korea). For each measurement, the guidelines of the International Society for Advances in Kinanthropometry will be followed (Marfell-Jones et al., 2012).
Change from Maximal isometric handgrip strength at 12 weeks
Previous recommendations indicate that maximal isometric handgrip strength (Lupton-Smith et al., 2022), was employed. The best position for testing was found to be sedentary, with the wrist and forearm in a neutral position, the elbow flexed at a 90-degree angle to the side of the body, the spine aligned, and the shoulder in a neutral position. A portable dynamometer (Jamar®, PLUS+, Sammons Preston, Patterson Medical, Warrenville, IL, USA) was used for testing. The dynamometer was placed in the first position, which promotes contact between the first phalanx of the thumb and index finger, to allow a firm grip on the device while preserving proper closure of the metacarpal, palatine, and interphalangeal joints based on hand size. Each participant performed three attempts with each hand after a 120-second rest.
Change from 30-second chair stand test at 12 weeks
The 30-second chair stand test (Bruun et al., 2019), which measures the number of repetitions performed standing and sitting in a chair with arms resting on the chest for 30 seconds, will be used to assess lower limb muscle strength and the ability to perform activities of daily living (Jones et al., 1999). The best of the three efforts will be taken into account for the analysis after three attempts, with a recovery of 120 seconds between them.
