Abstract

The aim of this study was to examinethe effectsof a combined training program(skill and physical training) along with Jacobson's relaxation technique onserum catecholamine levels and delayed onset muscle soreness indicators in male athletes
In this quasi-experimental study,30healthy amateur boxers aged between20to30years were considered. Participants were randomly divided into three groups based onVO2max,BMI, and boxing skill:a combined training group with Jacobson'srelaxation(n=10),a boxing training group with Jacobson's relaxation(n=10),and a control group(n=10)The boxing training consisted of correctly executed movements for30seconds using a direct punch with the front hand, back hand, and both hands.The physical conditioning exercises included push-ups,squat jumps,and shuttle runs,with a10%increase in exercise volume each week.Jacobson's relaxation exercises lasted for20minutes.Blood samples were taken before starting the training program and48hours after the last session to measure EPi,LDH,andCK.For statistical analysis,ANCOVAwas used for inter-group comparisons and paired t-tests for intra-group comparisons, using SPSS version 25 at a significance level of P ≤ 0.05.
Findings: The results indicated significant differences between the three groups (physical, skill-Jacobson, skill) in serum concentrations of EPi (P=0.001), LDH (P=0.003), and CK (P=0.016). Additionally, the paired t-test results showed a significant reduction in serum concentrations of epinephrine and lactate dehydrogenase post-test compared to pre-test in both the physical skill Jacobson group and the skill Jacobson group. However, this reduction was not significant for the variable of creatine kinase.
Conclusion: The present study showed that muscle relaxation intervention can have a significant impact on the levels of muscle damage and delayed soreness indicators as well as improve epinephrine levels
