Effects of Diet and Exercise Interventions on Cardiometabolic Risk Markers, Executive Function, and Intestinal Flora in Undergraduate Students: a Randomized Controlled Trial

The purpose of this study is to estimate the effects of diet and exercise interventions on body weight, cardiovascular metabolic markers, executive function, and intestinal flora among undergraduate students, as well as the underlying mechanisms.

Gedetailleerde beschrijving

In recent decades, unhealthy dietary patterns and insufficiency of physical activity have brought negative effects on human health, such as rapid increasing incidence of obesity, metabolic cardiovascular diseases, and mental disorders. The first line of prevention and therapy for these diseases is proper diet and lifestyle interventions. A series of studies conducted in vivo and vitro have shown that high-fiber diets and time-restricted eating present benefits in weight loss, reducing cardiovascular disease risk, and improving cognitive function. While, there is also a randomized controlled trial do not observe the effects of time-restricted eating on weight loss and decrease of metabolic risks. Meanwhile, few studies have examined the effects of high-fiber diets or time-restricted eating on executive function. Additionally, previous studies on high-fiber diets and time-restricted eating focused on middle-aged or elderly populations with some features of metabolic syndrome, while the effects on healthy young populations are unclear. More importantly, there are a small amount of studies exploring the combined effects of time-restricted eating and physical activity on metabolism and cognitive function. Therefore, our study is to estimate the effects of diet (high-fiber diets and time-restricted eating) and exercise (rope-skipping) interventions on body weight, cardiovascular metabolic markers, executive function, and intestinal flora among undergraduate students, as well as the underlying mechanisms.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Rope-skipping group
Participants would be required to take part in an exercise plan, under the instruction and guidance of professional sports teachers.
Gedragsmatig: Oefening
Drie keer per week touwspringen (elke keer 90 minuten, en na 20 minuten touwtjespringen een pauze van 10 minuten). Oefenarmband en slimme armband zouden worden gebruikt om het energieverbruik tijdens het onderzoek vast te leggen.
Experimenteel: Diet intervention group
Participants would be required to take part in a diet plan , including a high-fiber diet and time-restricted eating.
Gedragsmatig: Diet

Diet interventions include ten-hour time-restricted eating and a high-fiber diet.

  1. Participants will be instructed to take food from 7:30 AM until 5:30 PM and completely abstain from caloric intake for the remainder of the day (14 hours fast:10 hours eat). Only noncaloric beverages were permitted outside of the eating widow.
  2. According to the dietary recommendation proposed by Chinese Government and the existing dishes in the canteen , participants are instructed to eat following a high-diet recipe weekly from Monday to Friday which includes whole grain wheat rice, vegetables, fruits, and other foods rich in dietary fiber .
Experimenteel: Combined intervention group
Participants will receive both rope-skipping and diet interventions at the same time.
