About this trial

Exploring the efficacy and acceptability of exercise snacks (ES) and sprint interval training (SIT) could provide time-efficient, low-barrier alternatives for individuals, especially those who, due to 'lack of time, environment, and equipment,' struggle to meet traditional physical activity recommendations. This research aims to investigate the effects of ES and SIT, of equal exercise volume, on overweight adults.

Trial outcomes

Primary outcomes

Cardiorespiratory fitness

The change of maximal oxygen uptake (VO2max) before and after intervention.

Time frame

8 weeks

Secondary outcomes

Body composition

The change of body composition indexes (including fat mas, lean body mass, percentage of body fat) before and after intervention.

Time frame

8 weeks

Lipid profile

The changes in concentrations of high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol, and triglyceride before and after intervention.

Time frame

8 weeks

Endothelial function

The change of brachial Flow-Mediated Dilation (FMD) before and after intervention. Endothelial function will be assessed by FMD.

Time frame

8 weeks

Arterial stiffness

The changes of brachial-ankle pulse wave velocity and ankle brachial index before and after intervention.

Time frame

8 weeks

Other outcomes

Acceptability of the intervention

Intervention acceptability will be assessed using a theoretical framework of acceptability (TFA) questionnaire, completed only at the follow-up assessment. The seven domains of the TFA, along with overall acceptability, are measured using an 8-item questionnaire. The scale scores range from 0 to 5 with high scores indicating greater acceptability, and the total score representing the mean average of 7 individual domains of acceptability (each also rated 0-5).

Time frame

8 weeks

Physical Activity Enjoyment Scale (PACES)

A modified version of the PACES will be used, the PACES scale was modified by removing 1 irrelevant item ('I was very/not at all absorbed in the activity'). The 17 items are scored on a 7-point Likert scale, resulting in an overall enjoyment score between 17 (not enjoyable), 68 (neutral), and 119 (enjoyable).

Time frame

8 weeks

Intention Questionnaire

Intention questionnaire will be used after the 8 weeks intervention by a seven-point scale ranging from "Most likely never do this form of physical activity again (1)" to "Will likely do this three times per week every week (7)".

Time frame

8 weeks

Exercise Enjoyment Scale

Exercise enjoyment scale will be measured before, middle, and after intervention. The form will be presented to participants on a scale of 1 = 'not at all' to 7 = 'extremely,' and they will be asked, 'How much did you enjoy this exercise session?'

Time frame

4 weeks and 8 weeks
