Exercise and the Sleep for the Sarcopenic Elderly

Federal University of São Paulo28 enrolled

Overview

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.

Both a World Health Organization and the Brazilian Federal Government estimate that there is an abrupt increase in the number of elderly people. Data on approximately 10% of the elderly are affected by sarcopenia, a multifactorial syndrome that leads to the progressive and generalized loss of muscle mass and muscular strength, leading to a decrease in quality of life, increased physical dependence, fragility, morbidity and mortality. Parallel to the aging, well-being in the literature that the elderly present a phase advance, which promotes the change in the sleep-wake rhythm, as well as the reduction of time and sound quality. However, the view that a sarcophagus has a multifactorial feature sparing attention is for a possible non-sleep-wake rhythm and sleeping patterns of sarcopenic seniors at higher levels that occur in non-sarcopenic elderly. Interestingly, resistance training has often been used as a form of intervention both for the treatment of sarcopenia and for regulating the sleep-wake rhythm and to improve sleep parameters. In this sense, two questions need to be answered: Do higher sarcopenic individuals have no sleep-wake rhythm and are there no parameters when compared to non-sarcopenic elderly? The improvement of the resistance training analysis is also related to an improvement in the sleep-wake rhythm of the sleep parameters. In order to answer these questions the objective of the project is to evaluate whether elderly sarcophages present the sleep-wake rhythm and sleep quality at higher levels when compared to non-sarcopenic elderly and the benefits of resistance training for sarcopenic individuals related to rhythm regulation Sleep-wake and sleep patterns. Trained Non-Sarcopenic Elderly Group (GIT), Trained Elderly (GIT), Trained Elderly (GIT), Trained Elderly (ESSENCE) group; Group Elderly Controls No Sarcopenic (GC) and Elderly Group Sarcopenic Controls (GCS). The GIT and GIST groups underwent resisted training above 85% of 1 RM for 12 weeks and the GC and GCS groups will participate in lectures on lifestyle improvement every 15 days but are submitted to the training protocol. All volunteers are evaluated according to sleep objectives and subjects, as well as monitoring levels of anabolic and catabolic endocrine substances, inflammatory profile, body composition, physical and muscular performance of life before, during and after the experimental period

Interventions

SleepOTHER

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.

Resistance ExerciseOTHER

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.

Outcomes

Primary Outcomes

Polysomnography

The full polysomnography (PSG) will be performed overnight, using a digital polysomnography equipment and using the criteria indicated by the American Academy of Sleep for sleep staging (N1, N2, and N3), REM sleep, respiratory events, awakenings and periodic movements of the lower limbs.

Time frame: Pre-intervention end (12 weeks) intervention

Pitsburgh Sleep Quality Index

It is a self-applicable, easily interpreted instrument that has been extensively applied to several groups of people and collecting information on complaints about sleep, subjective quality of sleep, sleep onset latency, sleep duration, sleep efficiency, sleep disorder, use of sleeping pills and diurnal dysfunctions. Therefore, the sum of the points indicate that the higher the score the worse the quality of sleep, so when the score is less than 5 it will indicate absence of sleep disorders or a good quality of sleep, whereas if the sum is greater than 5 points the indication will be impaired sleep quality and presence of sleep disorders.
