Serum Irisin Dynamics in Response to Proprioceptive and Strengthening Training in Adolescent Inline Skaters
Abstract
Objective: This study investigated the effects of an eight-week proprioceptive and strengthening training program on serum irisin dynamics in adolescent inline skaters and explored its potential implications for performance optimization and injury prevention.
Material and Methods: A quasi-experimental pretest–posttest design with a control group was conducted involving 30 adolescent inline skaters (15 males, 15 females; aged 11–15 years). Participants were randomly allocated into an experimental group (n=15), which received the proprioceptive–strengthening intervention three times weekly for eight weeks, and a control group (n=15), which continued their regular training routines. Serum irisin levels were measured pre- and post-intervention. Statistical analyses included paired t-tests for within-group comparisons and independent t-tests for between-group differences, with a significance threshold set at p-value<0.05.
Results: The experimental group showed a significant increase in serum irisin concentration from 1.310±0.15 ng/mL at baseline to 3.349±0.25 ng/mL post-intervention (p-value<0.001), while the control group demonstrated only a modest rise (1.453±0.20 to 1.603±0.22 ng/mL, p-value=0.016). Between-group analysis confirmed a significant difference in post-test irisin levels favoring the experimental group (p-value=0.004).
Conclusion: The proprioceptive and strengthening training program effectively enhanced circulating irisin levels, indicating positive neuromuscular and metabolic adaptations. These findings suggest that integrating proprioceptive and strengthening exercises into routine training may support performance optimization and injury prevention in adolescent inline skaters.
