Effects of "Exercise Snack" in Individuals With Obesity (OBEXSNACK)
Effects of "Exercise Snack" on Physical Fitness,Vbody Composition, Enjoyment and Quality of Life in Outpatients With Obesity
Obesity is associated with reduced physical fitness, functional limitations, and poorer quality of life (Kell et al., 2001). Nutritional support and supervised exercise can improve weight management and physical health, but low motivation and perceived lack of time often limit participation to physical activity (Alberga et al., 2013; Baillot et al., 2021). Evidence shows that shorter-time exercise strategies may help overcome these barriers and support training adherence (Poon et al., 2020). Brief activity bouts distributed throughout the day, including vigorous intermittent lifestyle physical activity and structured "exercise snacks," may help to improve cardiorespiratory fitness, muscle function, and metabolic health (Islam et al., 2022; Ahmadi et al., 2024; Wang et al., 2024). Observational evidence also links VILPA to lower mortality risk (Stamatakis et al., 2023). Combining brief exercise bouts with education to interrupt prolonged sitting may therefore address both insufficient physical activity and sedentary behaviour (Dunstan et al., 2021; Dogra et al., 2022; Pinto et al., 2023). Generally, research has largely focused on healthy, inactive adults, with limited evidence in people with overweight or obesity (Jones et al., 2024). Rafiei et al. (2021) reported acute improvements in insulin and non-esterified fatty acid responses following brief stair-climbing bouts compared with prolonged sitting in adults with obesity. Schmidt et al. (2001) found comparable improvements in body composition and aerobic fitness following accumulated or continuous exercise during caloric restriction. The effects of exercise snacks combined with education to reduce sedentary behaviour nevertheless remain unclear. This study aims to evaluate the effects of an exercise-snacking programme on body composition, physical fitness, quality of life, and exercise adherence in adults with obesity.

실험적: Exercise Snack Group
Exercise snacks activity throughout the day |
10-week-home-based training protocol to improve cardiorespiratory fitness, muscular strength and stability performed through a short bout of physical activity called "exercise snack". The programme consists of high-intensity home-based exercises performed in five 2-minute bouts per day, spaced 2 hours apart, for 7 days (10 minutes of exercise per day). |
|
실험적: Traditional Fitness Group
Conventional circuit training exercise |
10-week-home-based training protocol to improve cardiorespiratory fitness, muscular strength and stability performed through a circuit-training mode. The programme consists of home-based exercises performed in a circuit-training format (time of work per set 20 s, time of rest between each exercise 10 s, time of rest between sets 2 min, total volume 3 sets) for a duration of 35 min with a frequency of 3 days per week while performing traditional strength and postural control exercises. |
