Current aspects of high-intensity interval training for older adults: a narrative review

Negative aspects of aging include a decrease in muscle mass/strength and maximal oxygen consumption (VO2max). The most beneficial adaptable protocol among the various exercise methods should be explored older adults. A combination aerobic strength training has been recommended as an effective required program to improve both VO2max guidelines. Recently, high-intensity interval (HIIT) become popular time-efficient way perform vigorous effectively, potentially improving strength/power it is rendered training. It often used by young middle-aged people with/without chronic disease. However, adaptation HIIT adults not fully established yet. effects submaximal on metabolic, physiological, adaptation, cognitive abilities have observed In contrast, there only limited evidence sprint (supramaximal), which also affects Because some barriers remain overcome when implementing adults, applicable protocols with stratification age physical function. Furthermore, data safety, clean-up methods, adherence participation rate, settled intensity during unsupervised are still lacking focused future studies.
