Effects of "Weekend Warrior" Exercise on Muscle Strength and Cardiorespiratory Finess in Sedentary Female University Students
15 de julio de 2026 actualizado por: 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.

Descripción detallada
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.

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Knee Push-up Performance
Periodo de tiempo: 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
Periodo de tiempo: 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
Periodo de tiempo: 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
Periodo de tiempo: 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
