Abstract

The purpose of this experimental research was to study and compare the effects of core muscle training on hip angle control in road cycling. The participants consisted of 20 male road cyclists who were divided into two groups, a core muscle training group (experimental group) of 10 people and a control group of 10 people. The experimental group underwent core muscle training for 8 weeks, 3 days per week. Before and after training, a 3D motion analysis system was used to measure images of athletes in a virtual cycling posture. Hip angles were measured at the bottom dead center, or the 6 o'clock crank position, and at the top dead center, or the 12 o'clock crank position. Data were analyzed using mean and standard deviation. Differences within groups before and after training were analyzed using a paired t-test, and differences between groups were analyzed using independent t-tests with a significance level of 0.05. The results showed that after 8 weeks of training, the experimental group had a statistically significant decrease in hip angle at the bottom dead center from 101.49 ± 3.20° to 97.21 ± 2.88° (p < 0.001) and at the top dead center from 56.13 ± 3.07° to 52.24 ± 4.28° (p = 0.02) compared with baseline. The control group did not show statistically significant differences. In addition, when comparing between groups, it was found that after 8 weeks of training the experimental group had a statistically significantly smaller hip angle in both positions at the 0.05 significance level. In conclusion, core muscle training for 8 weeks can effectively improve hip angle control in road cycling. Such improvement may result from increased stability of the torso and pelvis, resulting in more efficient force transfer and movement. This program can be incorporated into athletes’ daily training schedules to enhance cycling technique, training adaptation, and injury prevention.
