Exercise and the Sleep for the Sarcopenic Elderly

Summary

International data indicate that approximately 10% of the elderly will be affected by sarcopenia, a multifactorial syndrome that leads to the progressive and generalized loss of mass and muscular strength, leading to a decrease in quality of life, increased physical dependence, fragility, morbidity And mortality. Parallel to aging, it is well described in the literature that older people present a phase advance, which promotes alteration in the sleep-wake rhythm, as well as reduction of sleep time and quality.

In this sense, two questions need to be answered: Do sarcosis elderly present major changes in sleep-wake rhythm and in sleep parameters when compared to non-sarcopenic elderly? The improvement of sarcopenia through resistance training is also related to the improvement of the sleep-wake rhythm of the sleep parameters. In order to answer these questions, the objective of the project is to evaluate whether sarcopenic individuals present changes in the sleep-wake rhythm and sleep quality at higher levels when compared to non-sarcopenic individuals and whether the benefits of resistance training for sarcopenic individuals are related to Regulation of sleep-wake rhythm and sleep patterns.

Conditions

• Sarcopenia
• Sleep
• Physical Activity

Interventions

OTHER

Sleep

Initially, all volunteers will undergo the following pre and post-intervention tests: Polysomnography; Actigraphy for 10 days; Maximum exercise test; blood collection; Physical performance evaluation; Assessment of muscle strength, assessment of body composition; And application of questionnaires.

OTHER

Resistance Exercise

After these procedures, the sarcophagic elderly will Resistance training, will be performed according to the latest positioning of the American College of Sports Medicine for the training of the elderly . The training will last 12 weeks, 3 times / week, with intervals of 48h between the training sessions, which will have a maximum duration of 60min. The periodization of the training will be done in a linear way, in which the volunteers will be submitted to training with 1 series of 12 to 15 repetitions at 60% of 1RM in the first week; In the second week volunteers will train at 70% of 1RM, performing 2 sets of 10 to 12 repetitions; And from the third week to the end of the training period the volunteers will train at 80% of 1RM performing 3 sets of at most 8 replicates and the intervals between sets may range from 60min to 180min. The training load will be readjusted in the 6th week of training from a new 1RM test and the training will be on the same test equipment.
