High-intensity interval training (HIIT) is regarded as a highly effective training modality to improve cardiorespiratory and metabolic functioning, and it is a common practice in training regimens of many athletes, particularly those involved in endurance events. 1 In HIIT, repeated periods of

One specific approach to improving health and fitness through exercise that has received considerable attention in the literature, and among the general population, is high-intensity interval training (HIIT), which incorporates repeated bursts of intense aerobic exercise with periods of

intrinsic risk factors ( Nemoto, Gen-no, Masuki, Okazaki, & Nose, 2007 ). One of the main barriers to the habitual practice of physical exercise in adults is “the lack of time” ( Stutts, 2002 ). With this in mind, high-intensity interval training (HIIT) was developed with low-volume exercises. Furthermore

HIIT typically involves repeated bouts of high-intensity exercise interspersed with periods of low-intensity recovery or rest ( Shepherd et al., 2015 ). HIIT, as an intervention approach for previously inactive adults, has

To investigate the short- and long-term effects of concurrent strength and high-intensity interval training (HIIT) on octogenarian COPD patients, nine males (age = 84.2 ± 2.8 years, BMI = 29.3 ± 2.3) with low to severe COPD levels (2.1 ± 1.5 BODE index) underwent a supervised 9-week strength and HIIT exercise program. Training had a significant (p < .05) impact on senior fitness test scores (23–45%), 30-m walking speed (from 1.29 ± 0.29–1.62 ± 0.33 m/s), leg and chest press 1RM (38% and 45% respectively), maximal isometric strength (30–35%), and 6-min walking test (from 286.1 ± 107.2–396.2 ± 106.5 m), and tended to increase predicted forced vital capacity by 14% (p = .07). One year after the intervention all training-induced gains returned to their preintervention values except for the chest press 1RM (p <.05). Short-term concurrent strength and HIIT training increases physical fitness in the oldest-old COPD patients, and has potential long-term benefits.

High-intensity interval training (HIIT) is a short-duration form of exercise that entails a series of short, high-intensity efforts, punctuated by recovery periods ( Stork, Banfield, Gibala, & Martin Ginis, 2017 ). Studies have shown that several weeks of HIIT can bring

The majority of studies examining children’s responses to high-intensity interval exercise primarily utilized running; however, this modality does not require/include other important aspects of physical activity including muscular fitness. Purpose: To compare acute responses between a body weight resistance exercise circuit (CIRC) and treadmill-based (TM) high-intensity interval exercise. Method: A total of 17 boys (age = 9.7 [1.3] y) completed a graded exercise test to determine peak heart rate, peak oxygen uptake (VO2peak), and maximal aerobic speed. Sessions were randomized and counterbalanced. CIRC required 2 sets of 30-second maximal repetitions of 4 exercises. TM included eight 30-second bouts of running at 100% maximal aerobic speed. Both included 30-second active recovery between bouts. Blood lactate concentration was measured preexercise and postexercise. Rating of perceived exertion, affective valence, and enjoyment were recorded preexercise, after intervals 3 and 6, and postexercise. Results: Participants attained 88% (5%) peak heart rate and 74% (9%) VO2peak for CIRC and 89% (4%) peak heart rate and 81% (6%) VO2peak for TM, with a significant difference in percentage of VO2peak (P = .003) between protocols. Postexercise blood lactate concentration was higher following CIRC (5.0 [0.7] mM) versus TM (2.0 [0.3] mM) (P < .001). Rating of perceived exertion, affective valence, and enjoyment responses did not differ between protocols (P > .05). Conclusion: HR responses were near maximal during CIRC, supporting that this body-weight circuit is representative of high-intensity interval exercise.

-intensity exercise. High-intensity interval training (HIIT) is an exercise regimen that seems to be gaining more popularity in the general population as a quick and effective, yet enjoyable, way to partake in physical activity. High-intensity interval training, just like MICT, can take place in many different forms
