Effects of "Weekend Warrior" Exercise on Muscle Strength and Cardiorespiratory Finess in Sedentary Female University Students

15 juillet 2026 mis à jour par: Zhao Fangyuan, Chongqing Normal University
This randomized controlled trial evaluated the effects of a weekend warrior exercise pattern on muscle strength and cardiorespiratory fitness in sedentary female university students. Forty participants were randomly assigned to either a weekend warrior group or a regular exercise group. Both groups completed 150 minutes of moderate-intensity jogging and resistance exercise per week for 8 weeks, but the weekly exercise sessions were distributed differently. Body composition, functional muscular performance, and aerobic capacity were assessed before and after the intervention.

Description détaillée

This was an 8-week, assessor-blinded randomized controlled trial involving 40 sedentary female university students aged 18 to 25 years. Participants were randomly assigned in a 1:1 ratio to either a weekend warrior group or a regular exercise group.

The weekend warrior group exercised on two consecutive days per week, completing 50 minutes of jogging and 25 minutes of resistance training per session. The regular exercise group exercised on three days per week, including two 50-minute jogging sessions and one 50-minute resistance-training session. Both groups completed 150 minutes of moderate-intensity exercise per week. Exercise intensity was maintained at a Borg Rating of Perceived Exertion of 13-14 and monitored using the talk test.

Assessments were conducted before and after the intervention. Body composition was evaluated using the InBody 770. Muscular performance was assessed using knee push-ups, sit-ups, and body-weight squats, while aerobic capacity was assessed using the 12-minute run test. All assessments were performed by the same trained assessor under standardized conditions.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Weekend Warrior Group
Participants completed an 8-week weekend warrior exercise program on two consecutive days per week. Each session consisted of 50 minutes of moderate-intensity jogging and 25 minutes of resistance training, totaling 150 minutes of exercise per week.
Comportemental: Weekend Warrior Exercise
Participants exercised on two consecutive days per week for 8 weeks. Each session included 50 minutes of jogging and 25 minutes of resistance training. Exercise intensity was maintained at a Borg Rating of Perceived Exertion of 13-14 and monitored using the talk test. The total weekly exercise duration was 150 minutes.
Comparateur actif: Regular Exercise Group
Participants completed an 8-week regular exercise program on three days per week, including two 50-minute moderate-intensity jogging sessions and one 50-minute resistance-training session, totaling 150 minutes of exercise per week.
Comportemental: Regular Exercise
Participants exercised on three days per week for 8 weeks, completing two 50-minute jogging sessions and one 50-minute resistance-training session. Exercise intensity was maintained at a Borg Rating of Perceived Exertion of 13-14 and monitored using the talk test. The total weekly exercise duration was 150 minutes.

Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Knee Push-up Performance
Délai: Baseline and immediately after the 8-week intervention
The number of correctly completed knee push-ups performed continuously until volitional fatigue was recorded. Higher values indicate better upper-body muscular performance.
Baseline and immediately after the 8-week intervention
Sit-up Performance
Délai: Baseline and immediately after the 8-week intervention
The number of correctly completed sit-ups performed continuously until volitional fatigue was recorded. Higher values indicate better abdominal muscular performance.
Baseline and immediately after the 8-week intervention
Body-weight Squat Performance
Délai: Baseline and immediately after the 8-week intervention
The number of correctly completed body-weight squats performed continuously until volitional fatigue was recorded. Higher values indicate better lower-body muscular performance.
Baseline and immediately after the 8-week intervention
12-minute Run Distance
Délai: Baseline and immediately after the 8-week intervention
The total distance covered during the 12-minute run test on a flat outdoor track was recorded in meters. A longer distance indicates better cardiorespiratory fitness.
Baseline and immediately after the 8-week intervention

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
Body Weight
Délai: Baseline and immediately after the 8-week intervention
Body weight was measured using the InBody 770 bioelectrical impedance analyzer and reported in kilograms.
Baseline and immediately after the 8-week intervention
Change in Body Mass Index
Délai: Baseline and immediately after the 8-week intervention
Body mass index was assessed using the InBody 770 and reported in kilograms per square meter.
Baseline and immediately after the 8-week intervention
Body Fat Percentage
Délai: Baseline and immediately after the 8-week intervention
Body fat percentage was assessed using the InBody 770 bioelectrical impedance analyzer and reported as a percentage.
Baseline and immediately after the 8-week intervention
Waist-to-hip Ratio
Délai: Baseline and immediately after the 8-week intervention
Waist-to-hip ratio was calculated by dividing waist circumference by hip circumference. Lower values generally indicate lower central adiposity.
Baseline and immediately after the 8-week intervention
