Impact of Mental Effort Combined with Low-Intensity Resistance Training on Strength and Muscle Function in Older Adults Aged 65 to 85

What this Trial Is About

Researchers are evaluating the effects of combining maximal mental effort with low-intensity resistance training on strength and neuromuscular function in older adults aged 65 to 85. The study aims to determine if adding mental effort to low-intensity training improves strength and muscle function more than training alone. The research compares three groups low-intensity resistance training, low-intensity training with maximal mental effort, and a control group with no training. Participants assigned to the two training groups will complete 8 weeks of supervised low-intensity, whole-body resistance training twice a week. Each session lasts 45-60 minutes and includes five exercises such as leg press, chest press, and bicep curls. The mental effort group will focus on imagining maximal muscle contractions during each repetition, while the control group will not perform any training but will maintain their usual physical activity and diet. All participants will undergo assessments before and after the 8-week period to measure changes in strength, neuromuscular function, physical performance, and body composition. Tests include measurements of knee extensor strength, muscle activation, handgrip strength, walking speed, chair rise performance, muscle size, fat mass, and cognitive function. Monitoring will be conducted by research staff to track progress and adherence throughout the study.
