Abstract
Objective: To track leg stiffness in collegiate cross-country runners in response to a cross country race. Methods: Twenty-five collegiate cross-country runners were recruited for this study. They were assessed for leg stiffness 24 hours before and after a race as well as 48 hours after the race. Three jumping protocols were conducted: 1) static jump, 2) countermovement jump, 3) vertical hopping test. Each test was performed on two force plates and vertical ground reaction force data was collected. Results: No significant differences were found in post-hoc analysis for CMJ and EUR. SJ height increased significantly between 24 and 48 hours post-race. A significant main effect was found for SJ, CMJ and K. K decreased significantly 24 hours after the race (33.11 kN/m) compared to 24 hours before (36.84 kN/m). 48 hours after the race K increased significantly (36.30 kN/m) compared with 24 hours after the race. Conclusion: Leg stiffness appeared to decrease 24 hours following the race and then increase back to resting values 48 hours following the race.
