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

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

intervention ( Biddle & Batterham, 2015 ) is high-intensity interval training (HIIT). 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.

effects of short periods of intensified, or high-intensity interval training (HIIT), in athletes have become popular and underpinned by research studies showing it to be an effective method of training, 1 , 4 , 5 although not in all studies. 6 HIIT is a training method structured as repeated bouts

In this context, low-volume (75 min/week) high-intensity interval training (HIIT) has been recently suggested as a time-efficient strategy to improve body composition, metabolic profile, and cardiorespiratory fitness in inactive adults and in adults living with
