The current study investigated how the traditional sport of Jianzi (also called shuttlecock) affects physical fitness and body functions. The experimental group (EG) conducted a 15-week experiment with the Shuttlecock Model Club (SMC), while the control group (CG) participated in the physical education (PE) program at An Giang University (AGU) as usual. Both groups comprised 60 normal healthy female students. To evaluate fitness, this study included five tests: the 30-second sit-up test, the 30-meter sprint test, the shuttle run test (4 x 10 meters), the long jump test, and the 5-minute running test to measure maximal aerobic rate (MAS). We used 10 tests to evaluate physiological functions of the body such as BMI; Body fat %; Chest skinfold (mm); Waist skinfold (mm); Thigh skinfold (mm); Diastolic pressure; Flexion angle of the hip joint; Resting heart rate; Systolic pressure; VO2max. Except for explosiveness and core strength of the legs, this study demonstrated that EG improved more than CG in speed, agility, and maximal aerobic speed after completing 15 weeks. The EG group exhibited the most significant improvement in fitness tests, with MAS increasing by 23.60% and speed by 1.03%. The control group improved at a low level with an increased rate of 0.99% in speed and 6.87% in MAS. For functional body tests, the EG group also showed significant improvement compared to the CG. The highest improvement (18.39%) was in the variable waist skinfold (mm) in the EG.
