| Abstract | ||
| Background: Core stability training has recently attracted attention for optimizing performance and improving muscle recruitment and neuromuscular adaptation in both healthy and injured individuals. However, the specific impact of such training on the temporal characteristics of muscle activation remains unclear. Purpose: This study aimed to investigate the effect of a beginner’s core stability program on time to peak torque of trunk flexor and extensor muscles. Methods: Thirty-five healthy participants were randomly assigned to either a study group (n=20) or a control group (n=15). The study group comprised 10 males and 10 females with a mean age, weight, and height of 20.7±2.4 years, 66.5±12.1 kg and 166.7±7.8 cm respectively. The control group consisted of 6 males and 9 females with a mean age, weight, and height of 20.3±0.61 years, 68.57±12.2 kg and 164.28 ±7.59 cm respectively. Time to peak torques for both trunk flexors and extensors were measured pre- and post-intervention using the Biodex Isokinetic System. The study group participated in a 6-week core stability training program, while the control group maintained their usual activity level. Results: While no significant changes in time to peak torques were observed for either muscle groups within the control group (p > 0.05), the study group exhibited a significant decrease in the time to peak torque for both trunk flexors and extensors following the intervention period (p < 0.0001). Moreover, at the post-intervention measurement, the study group had a significantly lower time to peak torque for both muscle groups compared to the control group (p < 0.0001). Conclusion: The observed improvements in the muscle response indicated by the decrease in the trunk flexors andextensors’ time to peak torques in the study group, suggest that core stability training can be a valuable component of exercise programs designed to improve neuromuscular adaptation and overall fitness. | ||
