It is unclear how high-intensity, interval-type nontraditional exercise training programmes can be feasible and effective options for inactive obese individuals. This randomized controlled trial investigated the hypothesis that a 10-month high-intensity, interval-type neuromuscular training programme (DoIT) with adjunct portable modalities, performed in a small-group setting, induces improvements in psychological well-being, subjective vitality and exercise behavioural regulations in obese women. Associations between adherence, psychological and physiological indicators were also investigated. Forty-nine previously inactive obese females (36.4 ± 4.4 yrs) were randomly assigned to three groups (control; = 21, 10-month training; = 14, or 5-month training plus 5 month-detraining; = 14). DoIT was a supervised, progressive, and time-efficient (<30 min) programme that used 10-12 functional/neuromotor exercises and prescribed work and rest time intervals (20-40 sec) in a circuit fashion (1-3 rounds) for 10 months. Questionnaires were used to measure psychological distress, subjective vitality, and behavioural regulations in exercise at pre-, mid-, and post-intervention. The 10-month training reduced psychological distress (72%, = 0.001), external regulation (75%, = 0.011) and increased vitality (53%, = 0.001), introjected regulation (63%, = 0.001), intrinsic regulation (33%, = 0.004), and identified regulation (88%, = 0.001). A moderate to strong positive relationship was found between adherence rate and identified regulation scores ( = 0.59, = 0.001) and between VOpeak and identified regulation scores ( = 0.59, = 0.001). A mild dissociation between exercise intensity and perceived exertion was also observed. Our novel findings suggest that a 10-month implementation of a high-intensity interval neuromuscular training programme promotes positive psychological adaptations provoking exercise behavioural regulation and adherence while inducing weight loss in inactive obese women.
高强度、间歇性非传统运动训练方案对于不活跃的肥胖个体来说，其可行性和有效性如何尚不清楚。本随机对照试验旨在验证以下假设，即 10 个月的高强度、间歇性神经肌肉训练方案（DoIT）结合附加便携式模式，在小组环境中进行，可以改善肥胖女性的心理健康、主观活力和运动行为规范。还研究了依从性、心理和生理指标之间的相关性。49 名先前不活跃的肥胖女性（36.4±4.4 岁）被随机分配到三组（对照组；=21，10 个月训练；=14，或 5 个月训练加 5 个月脱训；=14）。DoIT 是一个监督、渐进和高效（<30 分钟）的方案，使用 10-12 种功能性/神经运动练习，并规定工作和休息时间间隔（20-40 秒），以电路方式（1-3 轮）进行 10 个月。在干预前、中和后使用问卷测量心理困扰、主观活力和运动行为规范。10 个月的训练降低了心理困扰（72%，=0.001）、外部调节（75%，=0.011）和提高了活力（53%，=0.001）、内化调节（63%，=0.001）、内在调节（33%，=0.004）和认同调节（88%，=0.001）。依从率与认同调节评分之间存在中度到高度正相关（=0.59，=0.001），VOpeak 与认同调节评分之间存在中度到高度正相关（=0.59，=0.001）。还观察到运动强度和感知用力之间的轻度分离。我们的新发现表明，高强度间歇神经肌肉训练方案的 10 个月实施促进了积极的心理适应，引发了运动行为规范和依从性，同时在不活跃的肥胖女性中诱导体重减轻。
