چکیده مقاله
Introduction This study compared the effects of eccentric quasi isometric EQI alone, with blood flow restricted EQI BFR , and conventional resistance training with BFR RT BFR on delayed onset muscle soreness DOMS , knee range of motion ROM and serum level of creatine kinase CK in trained men Methodology Twenty four resistance trained males age 22 5 ± 1 3 years; BMI 22 6 ± 1 6 kg/m² were randomly assigned to three groups n = 8 each : EQI, EQI BFR, and RT BFR All participants performed four sets of leg extensions at 70% of one repetition maximum BFR bands were inflated to 167 ± 11 mmHg in the EQI BFR and RT BFR groups DOMS was evaluated via a 100 mm Visual Ana logue Scale and quadriceps range of motion at pre exercise and 24, 48, and 72 hours post exercise Blood samples collected at the same time points were analyzed for creatine kinase Data were examined using repeated measures ANOVA with Bonferroni post hoc tests Discussion All groups experienced significant time dependent increases in DOMS and creatine kinase serum levels, peaking between 24 and 48 hours before trending toward baseline by 72 hours No significant differences emerged among EQI, EQI BFR, and RT BFR groups for VAS scores p = 0 473 , range of motion p = 0 189 , creatine kinase p = 0 563 Conclusion Among trained men performing moderate intensity leg extensions, eccentric quasi isometric, whether combined with blood flow restriction or not, and conventional resistance training with BFR protocols induced comparable DOMS and muscle damage responses Incorporating BFR into EQI exercise neither amplified nor mitigated muscle soreness or indicators of damage Future research should employ larger samples, higher intensities, and extended follow up periods to clarify potential differential effects
