Efeitos do treinamento resistido sobre a pressão arterial de idosos

Abstract

of adaptation and performance 4 , making the individual more vulnerable to pathological processes. In spite of the aforementioned progresses, the process of aging causes, after the 6 th decade of life, a marked decrease in muscle mass, strength and power 5 . Such modifications significantly reduce the capacity to perform the activities of daily living, increasing the degree of impairment of elderly individuals 6 . As a consequence, an increase in the number of falls is observed during this phase of life, which commonly results in fractures 7,8 . In fact, more than 90% of the fractures in elderly individuals are caused by falls -responsible for 70% of accidental deaths among those aged 75 or older 9 .To prevent this picture, it is important to adopt interventions that maintain muscular strength, as, even among the elderly, the neuromuscular system still retains part of its plasticity and can adapt in response to physical stimulation 10 . Thus, resistance exercises have shown to be a good solution.Several studies [11][12][13] have reported important muscular benefits of this type of training for the elderly population, such as the maintenance of muscle mass and a marked increase in muscle strength and power. For this reason, the resistance exercise has been considered a promising intervention to prevent or reverse, at least partially, the losses caused by the aging process. It has been strongly recommended for the elderly 14 , resulting in the improvement of functional capacity, health status, quality of life and degree of independence of elderly individuals 15 .In addition to muscle alterations, the aging process also causes alterations in the cardiovascular function, which, with the increasing age 16 , result in the progressive increase of the blood pressure. Such alterations can influence the cardiovascular responses to resistance training. It is interesting to observe that, even in young and middleaged individuals, the effects of resistance training on the cardiovascular function are controversial 17,18 . As they are being recommended to elderly individuals and as the latter present alterations in the cardiovascular function, it becomes important to investigate the effects of this training on the blood pressure of these individuals.The objective of this article was to conduct a narrative review on the subject, discussing the current scientific knowledge on the blood pressure responses and their possible regulatory, hemodynamic and neural mechanisms, after a period of resistance training in elderly individuals. The text will initially address the alterations in blood pressure and their mechanisms in relation to the aging process and, subsequently, the effects of resistance training on these parameters.Searches were conducted in libraries from the Biological Science area -electronic journals and virtual databases such AbstractThe aging process drastically reduces muscle mass, strength and power, decreasing the capacity to perform the activities of daily living. The practice of resistance exercises can reverse th...

“…Epidemiological and clinical studies have highlighted the bene ts of physical exercise (PE) for cardiovascular health [6][7][8][9] . One of these bene ts is related to the reduction in blood pressure (BP) during recovery after a single bout of PE, in comparison with resting values, and this phenomenon is called post-exercise hypotension (PEH) [10][11][12] .…”

Efeito do treinamento com pesos na pressão arterial de repouso em idosas normotensas

“…On the other hand, different studies have shown isolated reduction in SBP 10 , DBP 11 or in both simultaneously 12 . The differences observed in the magnitude of BP alteration after RT may be related to the influence of the manipulation of the variables involved in the prescription of RT and the characteristics of the studied sample [13][14][15] . Therefore, many studies which investigated the chronic effect of RT in rest BP in elderly subjects had different RT methods and individuals of both genders in their samples.…”
