Effects of high-intensity interval and continuous moderate aerobic training on fitness and health markers of older adults: a systematic review and meta-analysis
Key Points
- High-intensity interval training (HIIT) promotes similar or superior gains in physical fitness and health compared to continuous moderate-intensity training.
BACKGROUND & OBJECTIVE
Among older adults, research continues to illustrate the benefits of physical activity on function, fall prevention, and quality of life. However, most studies evaluate the impact of overall physical activity dose and not specific prescription parameters, such as frequency, mode, bouts, activity fragmentations, intensity, etc. Recent research has attracted attention to high-intensity interval training (HIIT).
The principal concept of HIIT is that a short period of intense exercise is alternated with brief recovery periods until the point of exhaustion. This method results in a simultaneous recruitment of aerobic and anaerobic energy systems, which distinguishes HIIT from continuous aerobic exercise. Due to the recent literature, the optimal combination of training components to optimize HIIT vs. continuous moderate-intensity training effects on health-related outcomes among older adults remains unclear.
The objective of this study was to compare the effects of HIIT and continuous moderate aerobic training on fitness and health markers in older adults.
High intensity interval training might be slightly superior for improving fitness and health in older adults, however continuous moderate aerobic training can be considered as a starting point for those with lower mobility.
