Appropriate exercise intensities, durations, and rest intervals are necessary for the appropriate selection of energy systems during exercise. With appropriate selections, specific adaptations for different athletic events can result (35, 157). Interval training is the basis for weight training and typically forms the foundation for the training programs of most anaerobic and aerobic sports. Although weight training and other forms of anaerobic interval training can increase aerobic power among aerobically untrained subjects to a small extent (4–10%) over a short term (184, 257, 265), major effects concern anaerobic factors. Weight training, sprint training, and other forms of anaerobic training have been shown to increase stores of phosphagens and glycogen, enhance the myokinase reaction (36, 176), result in preferential hypertrophy of type II fibers (102, 127), and generally enhance anaerobic metabolism (1, 35, 47), leading to improved performance.
The Integrative Coronary Heart Disease (CHD) Prevention Program
Published in Mark C Houston, The Truth About Heart Disease, 2023
For best results, an interval aerobic exercise program should consist of a five-minute warm-up period, followed by moderate to intense interval training involving large and multiple muscle groups lasting about 20 minutes, followed by a cooling-down period of about 5 minutes at the end.
Modern Rehabilitation Techniques for COVID-19
Published in Wenguang Xia, Xiaolin Huang, Rehabilitation from COVID-19, 2021
Activities recommended for ordinary patients during hospitalization are as follows. Exercise intensity: the intensity between resting (1.0 METs) and mild physical activity (< 3.0 METs) is recommended. Exercise frequency: twice a day, starting 1 hour after meals. Exercise time: activity time is determined according to the patient’s physical condition, maintaining 15–45 minutes each time. For patients who are prone to fatigue or are weak, they can perform interval training. Exercise types: respiratory rehabilitation exercise, walking on the spot, tai chi chuan, and exercises to prevent thrombosis.

High intensity interval training (HIIT) has become increasingly popular in recent decades and allows for a more time efficient method of exercise training (Foster et al. 2015). HIIT is defined as repeated bouts of high-intensity exercise separated by recovery or rest periods (Buckley et al. 2015). Each bout of high intensity exercise can last between 6 s to 4 min with recovery periods lasting between 10 s to 4 min (Romain et al. 2019). The target intensity for HIIT is usually between 80 and 100% of maximal oxygen consumption (VO2max) or maximal heart rate (HRmax) (Naves et al. 2018). Chronic HIIT training is well studied and the evidence remains consistent with respect to the positive impact on whole body physiological parameters including increases in anaerobic and aerobic capacity, insulin sensitivity, lower resting blood pressure, and improvements in endothelial function (Gibala et al. 2012). There is also evidence that HIIT can improve psychological health and quality of life (Stavrinou et al. 2018; Romain et al. 2019), and increase brain derived neurotrophic factor (BDNF) (Jiménez-Maldonado et al. 2018), which is a biomarker of neural health.

In recent years, there has been an increased interest in the use of interval exercise training among individuals with SCI.22 Interval training can generally be characterized as relatively short bouts of intense exercise interspersed with less intense exercise for recovery. The interest in interval training is due to the potentially large effects on all energy systems (i.e. “aerobic” and “anaerobic” metabolic pathways) within a small time requirement relative to traditional moderate-intensity continuous training.23–25 The most popular form of interval training is High-Intensity Interval Training (HIIT), which involves short high-intensity bouts of exercise (ranging from 80% of VO2reserve to supramaximal exercise) followed by low-intensity recovery bouts (ranging from 20% to 40% VO2reserve).26 A recent systematic review and meta-analyses concluded that HITT is an effective training strategy for improving cardiorespiratory fitness and cardio-metabolic health in non-SCI populations.27

Regardless of group, participants in the present study had a significant decrease in percent body fat with no difference between MIPS and PLA. This suggests that concurrent training consisting of resistance training and high intensity interval training improves body composition through a reduction in fat mass, supporting previous research (Arciero et al. 2014). Conversely, our data does not show increased lean mass that has been noted in other studies (Sale et al. 1990; De Souza et al. 2013; Cantrell et al. 2014). These discrepancies may be attributed to the differences in training programs. The present study consisted of progressive resistance training with an emphasis on strength performance while other training emphasize high-volume protocols (De Souza et al. 2013) where increases in lean mass would be anticipated. Indeed, a recent review (Schoenfeld et al. 2016) demonstrated a dose-relationship between training volume and increases in muscle hypertrophy. Despite these findings, our concurrent training model still elicited significant decreases in percent body fat and fat mass without significant differences between the two groups.
