Efficacy of dynamic Swiss ball training in improving the core stability of collegiate athletes

Introduction: The training of core muscles is key in sports training to improve performance and reduce the risk of injuries. However the most effective method to improve core musculature is still controversial. Therefore the objective of this study was aimed at investigating the effectiveness of dynamic Swiss ball training in reinforcing the core stability of collegiate athletes. Materials and methods: This two-group, two-factor research involved 67, 18- to 28-year-old collegiate athletes (18 females, 49 males) who were divided into experimental and control groups. The experimental group was provided dynamic Swiss ball training, whereas the control group was instructed to perform floor exercises. The groups underwent training for six weeks (three days per week). Four core stability tests (the Biering-Sorenson trunk extension, Side Bridge, prone bridge, and double leg lowering tests) were administrated pre- and post-training. Results: The mean scores of the participants in the core stability tests significantly improved after six weeks of training (p<0.05), but the between-group comparisons revealed that the experimental group significantly outperformed the control group in terms of enhancement in core stability (p<0.05). Conclusion: The relatively high improvement in core stability parameters after Swiss ball training suggested that these exercises are favorable alternatives to traditional floor exercises in strengthening the core muscles. The findings are expected to help athletes, coaches, trainers, and other strength and conditioning specialists involved in athletic training decide on appropriate training methods.
