EFFECTS OF HIIT ON MUSCLE STRENGTH IN OLDER ADULTS

Aging is accompanied by a series of changes including a decrease in strength and muscle mass. High intensity interval training is an exercise modality that has functional, cardiorespiratory and musculoskeletal benefits in older adults. The objectives of this review are to examine the existing scientific evidence to determine the effects of high-intensity interval training on muscle strength in older adults as an element of prevention and treatment of sarcopenia. Obtaining the conclusion that HIIT training has improvements in functional and cardiorespiratory capacity, in body composition, has benefits on muscle strength, increases muscle architecture and quality, and is associated with muscle hypertrophy in older adults.
