Abstract：
Nonadherence to and dropout from regular exercise and physical activity are important reasons why the field of exercise science has yet to fulfill its promise of improving public health on a global scale. Researchers have claimed that High-Intensity Interval Training (HIIT) is a feasible and sustainable exercise modality that may result in higher long-term adherence than moderate-intensity continuous exercise. If true, this would be a breakthrough discovery that could unlock the potential of exercise as a health-promoting intervention. We performed a systematic search of the literature and identified eight trials comparing HIIT to moderate-intensity continuous exercise, all of which involved follow-up periods of at least 12 months (i.e., SWIFT, Small Steps for Big Changes, SAINTEX-CAD, SMARTEX-HF, Generation 100, FITR, OptimEx-Clin, HITTS). Findings from these trials demonstrate that, while unsupervised, individuals initially assigned to HIIT tend to exercise at lower-than-prescribed intensities and HIIT groups demonstrate no advantage in long-term adherence.
摘要：
不坚持和退出定期运动和体育锻炼是运动科学领域尚未实现其在全球范围内改善公共卫生的承诺的重要原因。研究人员声称，高强度间歇训练（HIIT）是一种可行且可持续的运动方式，与中等强度连续运动相比，可能会导致更高的长期依从性。如果为true，这将是一个突破性的发现，可以释放运动作为促进健康的干预措施的潜力。我们对文献进行了系统的搜索，并确定了8项将HIIT与中等强度连续运动进行比较的试验，所有这些都涉及至少12个月的随访期(即，SWIFT,大变革的小步骤，SAINTEX-CAD,SMARTEX-HF,第100代，FITR，OptimiEx-Clin,HITTS).这些试验的结果表明,虽然无人监督，最初被分配到HIIT组的个体倾向于以低于规定的强度进行运动,而HIIT组在长期依从性方面没有优势.
