Weekend Warrior Exercise in Sedentary Female University Students

2026年7月10日 更新者：Ziren Zhao、Chongqing Normal University

Effects of Weekend Warrior Exercise on Aerobic Capacity and Skeletal Muscle Strength in Sedentary Female University Students: A Randomized Controlled Trial

This single-center, single-blind, three-arm randomized controlled trial aims to compare the effects of weekend-concentrated exercise, regularly distributed exercise, and usual lifestyle on aerobic capacity and skeletal muscle strength in sedentary female university students. Sixty participants aged 18 to 25 years will be randomly assigned in a 1:1:1 ratio to a weekend warrior group, a regular exercise group, or a control group.

The intervention will last 8 weeks. Both exercise groups will complete 150 minutes of moderate-intensity exercise per week, combining resistance exercise and jogging, but the exercise sessions will be distributed differently across the week. The control group will maintain its usual lifestyle without receiving the prescribed exercise intervention.

The primary outcomes are peak oxygen uptake and isokinetic peak torque. Secondary outcomes include body composition, maximal heart rate, maximal power and time to exhaustion, 12-minute run performance, isokinetic mean torque, physical activity, sleep quality, exercise self-efficacy, emotional status, cognitive function, adherence, feasibility, and exercise-related adverse events.

详细说明

This study is designed to test whether concentrating the recommended weekly exercise volume into a weekend pattern produces comparable benefits to a regularly distributed exercise pattern in sedentary female university students. The intervention emphasizes a dose-matched comparison in which both exercise groups complete the same total weekly exercise duration, while the distribution of exercise sessions differs.

After baseline screening and assessment, participants will be assigned to one of three parallel groups using a 1:1:1 allocation ratio. The weekend warrior group will complete two consecutive exercise days per week, whereas the regularly distributed exercise group will complete three exercise days per week. Both exercise programs will last 8 weeks and include resistance exercise combined with moderate-intensity jogging.

Resistance exercise will primarily target the lower limbs, core, and major muscle groups. Exercises may include squats, lunges, glute bridges, calf raises, and planks, using body weight, elastic bands, or light equipment as appropriate. Jogging may be performed as continuous jogging or a run-walk format according to individual fitness level. Exercise intensity will be monitored using heart rate and rating of perceived exertion. Jogging intensity will generally be maintained at approximately 60% to 75% of maximal heart rate or a rating of perceived exertion of 12 to 14. Each session will include warm-up, supervised exercise, and cool-down activities.

The main contrast between the two exercise interventions is the weekly distribution of exercise rather than total weekly duration. The control group will maintain usual study and lifestyle habits during the 8-week period. Study staff will monitor adherence, perceived exertion, discomfort, and exercise-related events during the intervention. Outcome assessors will be blinded to group allocation when feasible.

参与者组/臂
干预/治疗
实验性的：Weekend Warrior Exercise Group
Participants will complete an 8-week weekend-concentrated exercise program. They will exercise on two consecutive days per week, completing 30 minutes of resistance exercise and 45 minutes of jogging on each exercise day, for a total of 75 minutes per day and 150 minutes per week.
行为的：Weekend Warrior Exercise
Participants will complete an 8-week weekend-concentrated exercise program on two consecutive days per week. On each exercise day, participants will perform 30 minutes of resistance exercise and 45 minutes of moderate-intensity jogging, resulting in 75 minutes per day and 150 minutes per week. Resistance exercises will target the lower limbs, core, and major muscle groups and may include squats, lunges, glute bridges, calf raises, and planks. Jogging intensity will be maintained at approximately 60% to 75% of maximal heart rate or a rating of perceived exertion of 12 to 14. Each session will include warm-up and cool-down activities.
有源比较器：Regular Exercise Group
Participants will complete an 8-week regularly distributed exercise program. They will exercise on three days per week, completing 20 minutes of resistance exercise and 30 minutes of jogging during each session, for a total of 50 minutes per session and 150 minutes per week.
行为的：Regularly Distributed Exercise
Participants will complete 150 minutes of moderate-intensity exercise per week for 8 weeks, distributed across three days. Each session will include 20 minutes of resistance exercise targeting the lower limbs, core, and major muscle groups, followed by 30 minutes of jogging. The exercise content, intensity-control principles, and safety requirements will be comparable to those of the weekend warrior group.
无干预：Control Group
Participants will maintain their usual study and lifestyle habits during the 8-week study period and will not receive the exercise intervention prescribed by the study. Their participation in additional structured exercise will be monitored.
