Abstract
High-Intensity Interval Training (HIIT) has become a healthy alternative in recent years at cardiac, muscle and adipose levels for different groups. Although it is an issue frequently discussed now days, there is not a clear consensus on its usefulness and application in senior groups. The objective of this paper was to examine scientific literature on HIIT as an alternative of physical activity in older adults (>60 years of age) and determine its usefulness from a healthy point of view. This review included studies: (1) on groups of senior adults (> 60 years of age), (2) their intervention included HIIT, and (3) their focused was on the relationship of this training with health. A total of 16 studies met all the criteria. It can be concluded that HIIT is a valid and safe training for seniors (>60 years). Benefits include cardiovascular, pulmonary, hemodynamic, lipid, muscle, and cognitive improvements.
