Purpose: This study investigated the effects of intensive selected physical exercises on students’ physical fitness.
Methods: This randomized controlled trial was conducted with 120 participants aged 18-19. The exercise group participated in 12 weeks of intensive, selected physical exercises, while those in the control group maintained their usual exercise routine. Physical fitness tests were administered to both groups to assess the effect of the intervention. One-way ANOVA was used to compare the groups, and paired samples t-tests were conducted to assess within-group changes. 
Results: There were significant between-group differences at the endpoint for six key tests: handgrip strength (F=7.891, P=0.006), sit-ups (F=51.969, P<0.001), standing long jump (F=15.673, P=0.006), 30-meter sprint (F=21.925, P=0.006), 4×10-meter shuttle run (F=9.048, P=0.003), and the 5-minute run test (F=7.591, P=0.007). These findings indicate that the exercise group exhibited significant enhancements in upper and lower limb strength, abdominal strength, speed, agility, body control, and endurance compared to the control group following 12 weeks of intensive, selected exercise training.
Conclusion: Intensive selected physical exercises demonstrate superior effectiveness in enhancing student physical fitness compared to traditional class activities, as evidenced by improved performance on physical fitness tests.
