Time Restricted Fasting and Aerobic Exercise Interventions Among Sedentary Adults

Not Applicable
Completed
Conditions
Sedentary; Aging
Interventions
Behavioral: Aerobic Exercise
Behavioral: Time Restricted Fasting
Registration Number
NCT05865639
Lead Sponsor
Guangzhou Sport University
Brief Summary

This project will determine the independent and combined effects of aerobic exercise and time restricted fasting on cardiovascular risks among sedentary middle-aged and elderly adults. The online intervention period will be eight weeks. Before and after the intervention, arterial stiffness, cardiac autonomic nervous, body composition, glucolipid metabolism, sleep and eating habits, inflammatory reaction, sedentary behavior and physical activity level will be measured and compared between groups who are doing either aerobic exercise, time restricted fasting, both aerobic exercise and time restricted fasting, or who are in a control group. Adverse reaction, sleep and eating quality, life quality and adherence to the interventions and hunger/satiety will also be measured.

Primary Outcome Measures
NameTimeMethod
Change of cardiovascular risk estimated by ankle-brachial indexFrom baseline to after 8 weeks intervention
Change of cardiovascular risk estimated by heart rate variabilityFrom baseline to after 8 weeks intervention
Change of cardiovascular risk estimated by pulse wave velocityFrom baseline to after 8 weeks intervention
Change of cardiovascular risk estimated by flow-mediated transitionFrom baseline to after 8 weeks intervention
Change of cardiovascular risk estimated by cytokines levelFrom baseline to after 8 weeks intervention

Fasting matrix metalloproteinases, norepinephrine, and neuropeptide Y cytokines level in blood

Secondary Outcome Measures
NameTimeMethod
Triglycerides in bloodFrom baseline to after 8 weeks intervention

Fasting triglycerides in blood

Sleep qualityFrom baseline to after 8 weeks intervention

Self-reported: sleep quality was indicated by the Pittsburgh Sleep Quality Index (PSQI) Questionnaire. The maximum score of the sleep quality index is 21 points,scores higher than 5 indicate poor sleep quality, with higher scores indicating poorer sleep quality.

Physical activityFrom baseline to after 8 weeks intervention

Physical activity were measured by using accelerometer (ActiGraph GT3X+ model, USA).Measured by using accelerometer (ActiGraph GT3X+ model, USA). Accelerometer was used for 7 consecutive days, being affixed to the nondominant wrist.

WeightFrom baseline to after 8 weeks intervention

In kg

body fatFrom baseline to after 8 weeks intervention

In kg

Diet habitsFrom baseline to after 8 weeks intervention

Self-reported: diet habits were assessed using the Adult Eating Behavior Questionnaire (AEBQ).

With higher scores indicating worse eating habits (represented by emotional over-eating and emotional under-eating) or better dietary (represented by food responsiveness, enjoyment of food, satiety responsiveness, food fussiness and slowness in eating).

Adherence to interventionFrom baseline to after 8 weeks intervention

Self-reported: WeChat application, number of completed exercise sessions out of those prescribed, in percentage.

Lean body massFrom baseline to after 8 weeks intervention

In kg

Body fat percentageFrom baseline to after 8 weeks intervention

In percent of total body mass

Life qualityFrom baseline to after 8 weeks intervention

Self-reported: life quality was indicated by The World Health Organization Quality of Life (WHOQOL)-BREF Questionnaire. With higher scores indicating better life quality.

Cholesterol in bloodFrom baseline to after 8 weeks intervention

Total fasting cholesterol in blood

Diet in takeFrom baseline to after 8 weeks intervention

Self-reported: Mint Health application.

Body mass IndexFrom baseline to after 8 weeks intervention

In kg/m\^2

Low density lipoprotein in bloodFrom baseline to after 8 weeks intervention

Fasting low density lipoprotein in blood

Sedentary activityFrom baseline to after 8 weeks intervention

Sedentary activity were measured by using accelerometer (ActiGraph GT3X+ model, USA).Measured by using accelerometer (ActiGraph GT3X+ model, USA). Accelerometer was used for 7 consecutive days, being affixed to the nondominant wrist.

Inflammation levelFrom baseline to after 8 weeks intervention

Inflammation level were measured by Enzyme-linked immuno sorbent.
