The Effect of High-Intensity Interval Training (HIIT) on Physical Activity Adherence on Low Active Adults

Abstract: Only 10% of Americans are active at the recommended levels and therefore, it is important to examine the best way to motivate individuals to exercise. The most common barrier reported to exercise is lack of time. High-Intensity Interval training (HIIT) has emerged as a time efficient exercise method that has similar benefits as traditional exercise methods. The purpose of this study was to analyze the literature examining the effect of HIIT on adherence to exercise among low active adults. Twenty articles were identified using key terms and the five best designed were chosen for the purpose of this review. There were several limitations of the studies including a lack of standardized HIIT interventions, disagreements regarding the psychological effects, and all studies were administered in lab settings, which may not generalize to the real world. Future research should focus on establishing a well-defined HIIT intervention, explore the effect of HIIT on affect and mood, and examine the efficacy of a home-based intervention.
