Eccentrically Reinforced Resistance Training vs. Traditional Resistance Training in Sedentary Older Women

Summary

There are easily accessible and safe strategies, such as physical exercise, that can contribute to reducing depressive symptoms and to the preservation of physical and executive function in elderly women. Resistance exercise is defined as performing in water or on land. It involves exercise using a constant load or a uniform weight regardless of the training program. There are many types of resistance exercise equipment, including free weights, pneumatic resistance machines, and elastic bands. Specifically, eccentric muscle contraction occurs when the force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in forced lengthening of the muscle-tendon system while contracting.

To date, a body of evidence has been found derived from randomized controlled trials, which have compared the effectiveness of aerobic, resistance exercise and Pilates in decreasing depressive symptoms and improving physical and executive function in elderly women.

Although there are experimental studies demonstrating the effectiveness of physical exercise, the effect of short-term eccentrically reinforced strength training on depressive symptoms, physical and executive function in sedentary older women is unclear.

Therefore, this study aims to evaluate the safety and effect of eccentrically reinforced resistance exercise vs. traditional resistance training on depressive symptoms, physical and executive function, quality of life, different manifestations of muscle strength, body composition, vital signs and abdominal circumference, risk of falls, quality of sleep sedentary older women for 8 weeks.

Interventions

BEHAVIORAL

Eccentrically strengthened resistance exercise

For each resistance exercise session, 6 to 7 generic exercises will be performed, involving small and large muscle groups (leg extension, leg curl, biceps curl, triceps extension, seated row, shoulder flexion, and shoulder raise). They will perform with 4 sets of 8 repetitions, with a break between exercises of 1 minute and between sets of 2 minutes. They perform those exercises with high intensity (ever 10 on the OMNI-RES Scale).

BEHAVIORAL

Traditional resistance training

For each resistance exercise session, 6 to 7 generic exercises will be performed, involving small and large muscle groups (leg extension, leg curl, biceps curl, triceps extension, seated row, shoulder flexion, and shoulder raise). They will perform with 4 sets of 8-12 repetitions, with a break between exercises of 1 minute and between sets of 2 minutes. They perform those exercises with moderate and high intensities (6 to 10 on the OMNI-RES scale).
