简要总结
The goal of this randomized trial is to find out if an 8-week korfball-based training program can improve lower-body strength and jumping ability in children aged 10-12 years. Korfball is a mixed-gender sport that promotes teamwork and equal participation.
The study will test two main questions:
Does korfball training increase explosive leg power measured by the Margaria-Kalamen Stair Climb Test? Does korfball training improve performance in the Standing Long Jump Test?
Children are randomly assigned to one of two groups:
Korfball Training Group: Participants take part in supervised korfball-based exercise sessions 3 times per week for 8 weeks, in addition to their normal school activities.
Control Group: Participants continue with standard school physical education classes only.
All participants complete both the Margaria-Kalamen Stair Climb Test and the Standing Long Jump Test before and after the 8-week period.
This study will show whether korfball training is an effective and inclusive way to improve explosive leg power and motor skills in school-aged children.
详细描述
Korfball is a mixed-gender team sport that emphasizes cooperation, spatial awareness, and technical ball skills. Its unique format prohibits gender-based physical contact and requires players to coordinate offensive and defensive movements in a cooperative way. These characteristics make korfball not only a socially inclusive activity but also a potential tool for motor development in children. However, there is limited experimental evidence examining the physical benefits of korfball training in youth populations.
This randomized controlled trial was designed to investigate whether an 8-week korfball-based training program can improve explosive lower-body performance in children aged 10-12 years. A total of 30 participants were randomly assigned to either a korfball training group or a control group. The training group completed three 90-minute sessions per week for eight weeks, in addition to their regular school physical education classes. The control group continued with their standard school-based activities only.
The intervention program included structured korfball drills such as passing, shooting, lay-up techniques, and defensive footwork. Sessions were organized progressively from basic skills to more complex game-like movements. All training sessions were supervised by a certified physical education teacher to ensure safety and protocol fidelity.
Two validated physical performance tests were used to assess outcomes:
Margaria-Kalamen Stair Climb Test (MK): to evaluate anaerobic power by measuring the time taken to ascend stairs with predetermined step intervals.

研究组 & 干预措施
Control
Control group continued with their usual school-based physical education classes without any additional training (8 week).
Korfball Training Group
The korfball training group participated in an eight-week korfball-based movement training program, three times a week, each session lasting 90 minutes. Training consistently occurred from 16:00 to 18:00 in an outdoor korfball court under coach supervision. Each session started with 10 minutes of warming up and 5 minutes of stretching exercises. The main session included 65 minutes of korfball-based movement training, followed by a 10-minute cool-down period.
干预措施: Korfball-Based Movement Training (Other)
结局指标
主要结局
Margaria-Kalamen Stair Climb Test (Explosive Power)
时间窗: Baseline (pre-test) and after 8 weeks of training (post-test)
Change in anaerobic power output (watts) measured using the Margaria-Kalamen stair climb test. Participants sprinted up a staircase stepping on the 3rd, 6th, and 9th steps. Anaerobic power was calculated using the standard formula P = (m × g × h) / t, where m is body mass (kg), g is gravitational acceleration (9.81 m/s²), h is the vertical height between the 3rd and 9th steps (1.2 m), and t is the time taken to ascend (s).
Standing Long Jump Test (Horizontal Explosive Power)
时间窗: Baseline (pre-test) and after 8 weeks of training (post-test)
Change in horizontal jump distance (cm) measured using the Standing Long Jump test. Participants jumped forward from a standing start with both feet together, and the best of three trials was recorded.
