Comparison of physical effect between two training methods for individuals with substance use disorder

Area of Science:

• Exercise Physiology
• Addiction Medicine
• Rehabilitation Science

Background:

• High-intensity interval training (HIIT) is increasingly used for health promotion in various populations.
• Exercise, including HIIT, may aid individuals with substance use disorder (SUD) in reducing cravings and improving mental health.
• The comparative physical rehabilitation benefits of HIIT versus moderate-intensity continuous training (MICT) for individuals with SUD remain unclear.

Purpose of the Study:

• To compare the effects of HIIT and MICT on the physical fitness of individuals with SUD.
• To assess changes in physical fitness parameters and craving levels over a 12-month intervention period.

Main Methods:

• A randomized controlled trial involving 120 individuals with amphetamine-type stimulant dependence.
• Participants were assigned to either a HIIT or MICT group, training three times weekly for 12 months.
• Physical fitness (BP, VC, hand grip, push-up, sit-and-reach, balance, reaction time) and craving levels were assessed at baseline and multiple follow-ups.

Main Results:

• Both HIIT and MICT groups showed significant within-group improvements in all assessed physical fitness parameters.
• Craving levels decreased significantly in both groups after 12 months.
• No significant differences in physical fitness or craving levels were found between the HIIT and MICT groups.

Conclusions:

• Both HIIT and MICT demonstrate positive effects on physical fitness and craving reduction in individuals with SUD.
• The study suggests that neither exercise modality offers a superior benefit over the other for this population within the study period.
