This study investigates the effects of lower limb leg press power training combined with visual feedback games on the physical performance, cognitive function, and heart rate variability (HRV) of older adults aged 65 and above. Participants were divided into an experimental group and a control group, with the experimental group engaging in leg press exercises combined with visual games twice a week for 12 weeks.
This study aims to investigate the effects of lower limb leg press power training combined with visual feedback games on the physical and cognitive health of the elderly. With the aging population increasing, the decline in muscle strength and cognitive function has become a significant challenge for older adults. To address these health issues, this study plans to recruit 40 participants aged 65 and above and randomly assign long-term care centers into an experimental group and a control group. The experimental group will perform leg press training combined with visual feedback games twice a week for 12 weeks, while the control group will continue their usual daily activities.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control Group | No Intervention | This group will not receive any specific muscle power intervention. | |
| Lower Limb Strength Training Program with Visual Feedback | Experimental | This lower limb explosive strength training system integrates visual feedback games and is equipped with angle and force sensors to simultaneously output the power of the left and right legs, as well as maximum explosive force and pushing force. Users can immediately understand the balance of leg strength and make adjustments, making it particularly suitable for the elderly to improve lower limb strength or for rehabilitation training. The gamification of the system enhances the fun of training, while data quantification allows progress tracking, making the training more precise and effective. Additionally, after the game ends, data can be exported to Excel for further analysis to identify issues in the pushing process and optimize the training plan. |

This is a randomized controlled trial with a parallel assignment model. Participants are randomly assigned to either the experimental group or the control group. The experimental group undergoes lower limb leg press power training combined with visual feedback games twice a week for 12 weeks, while the control group maintains their usual daily activities. The outcomes are assessed before and after the 12-week intervention, focusing on physical performance, cognitive function, and heart rate variability (HRV).

Two long-term care centers were selected for the study. One center was randomly assigned to the experimental group through a lottery system, while the other served as the control group.
