Abstract

The loss of muscle strength, power and mass is significant with the aging process. As a result, the elderly population experience a decline in their daily functional capacities such as walking, climbing stairs and doing physical activities. The conventional strength training is prescribed to prevent skeletal muscle atrophy but the training intensity could be a risk to seniors with chronic diseases. Taking that into account, it was created in Japan a modality of training called Kaatsu Training which utilizes the restriction of blood flow with inflatable cuffs.The Kaatsu training has been used in many populations with different purposes: performance, rehabilitation and therapeutic. However, there are few studies, with controversial results, which evaluated the effects of low intensity strength training combined with blood flow restriction in elderly people with greater functional impairment, especially regarding the safety of vascular outcomes. It is well-known that one of the most important effects of physical exercise in aging people suffering from chronic illnesses, especially concerning safety and clinical benefits, relates to arterial stiffness and correlated factors.Thus, the purpose of the present study is to evaluate the acute and chronic effects of low intensity strength training with or without moderate blood flow restriction on muscle vasodilation and arterial stiffness in elders with low gait speed. In addition, the responses of prothrombotic factors in blood coagulation, the impact on heart rate and arterial pressure will be assessed. (AU)
