Key result
High-intensity interval training and moderate-intensity continuous training both significantly improved physical fitness and reduced craving in substance use disorder, with no significant differences.
Why the study?
It was not clear whether high-intensity interval training provides better physical rehabilitation benefits than moderate-intensity continuous training in individuals with substance use disorder.
Does High-intensity Interval Training (HIIT) improve physical fitness and reduce craving compared to Moderate-intensity continuous Training (MICT) in male individuals with amphetamine-type stimulant dependence?

Does High-intensity Interval Training (HIIT) improve physical fitness and reduce craving compared to Moderate-intensity continuous Training (MICT) in male individuals with amphetamine-type stimulant dependence?
Both high-intensity interval training and moderate-intensity continuous training are equally effective at improving physical fitness and reducing cravings in men with amphetamine-type stimulant dependence.

Either HIIT or MICT can be recommended in amphetamine-type stimulant dependence; extends evidence for exercise in substance use disorders.
Background: High-intensity Interval Training (HIIT) has recently been widely used for health promotion in healthy people and patients with chronic diseases. It is not clear whether HIIT can bring better physical rehabilitation benefits to individuals with substance use disorder (SUD) than that of Moderate-intensity continuous Training (MICT). The study aimed to compare the effects of HIIT versus MICT on the physical fitness of individuals with SUD.Methods: A total 120 individuals with amphetamine-type stimulant dependent from a compulsory drug rehabilitation center voluntarily took part in this study. They were randomly assigned to the HIIT group (experimental group) and MICT group (control group). The subjects in experimental group received HIIT training three times a week (80%-85%HRMax, 60min). The exercise included rope jumping, running, weight training and basketball game. The subjects from control group received MICT 3 times a week (60%HRMax, 60min), including Tai Chi, mind-body exercise and recreation activity. Physical fitness assessment were performed at the baseline, 3 months, 6 months, 9 months and 12 months exercise intervention including blood pressure (BP), vital capacity (VC), hand grip, push-up, sit-and-reach, one-leg-stand with eyes closed and choice reaction time. The craving level was assessed using the visual analog scale （VAS）at the baseline, 6 months and 12 months. A two-way repeated measures analysis of variance (ANOVA) was applied to test whether the intervention were different after 12 months.Results: The within-group factor displayed significant changes in HIIT and MICT groups in terms of the systolic BP (F (4,336) =12.799), diastolic BP (F(4,336) =9.495), VC (F(4,336)=18.121), hand grip (F(4,336)=34.815), sit-and-reach (F(4,336) =13.871), choice reaction time (F(4,336) =20.603), one-leg-stand with eyes closed (F(4,336) =14.495) and push-up (F(4,336) =28.805). The craving level decreased after 12 months intervention in both groups (F(2,168) =11.25, P<0.001), but there was not significant differences between HIIT and MICT group.Conclusion: Both HIIT and MICT can promote the physical fitness rehabilitation for individuals with SUD.

yang et al. (2020) conducted an RCT in Substance Use Disorder (Amphetamine-type stimulant dependent) (n=120). High-intensity Interval Training (HIIT) vs. Moderate-intensity Continuous Training (MICT) (55-65% HRMax, 60 minutes, 3 times a week) was evaluated on Physical fitness (blood pressure, vital capacity, hand grip, push-up, sit-and-reach, one-leg-stand with eyes closed, choice reaction time). High-intensity interval training and moderate-intensity continuous training both significantly improved physical fitness and reduced craving in substance use disorder, with no significant differences.
