Purpose: This examined the effect of Kinesio taping pre-intervention on the pain, tenderness, proprioceptive sensation, and muscle strength associated with delayed onset muscle soreness. Methods: Thirty subjects were divided into a Kinesio taping application group of 15 subjects and a control non-taped group of 15 subjects, and the changes in individual variables were analyzed before taping and at 24, 48, and 72 hours after taping using two-way repeated ANOVA. Post-hoc t-tests were conducted in the cases with intergroup interactions, and the significance level ${\alpha}$ was set to ${\alpha}=0.01$. Results: The changes in pain during rest were significantly different only for the times, while the changes in pain during exercise were significantly different for the times, interactions between the times and groups, and intergroup changes (p<0.05). The changes in tenderness were significantly different for the times and for interactions between the times and groups (p<0.05). The changes in proprioceptive sensation were significantly different for the times, interactions between times and groups, and intergroup changes (p<0.05). The changes in muscle strength were significantly different only for the times (p<0.05). Conclusion: The application of Kinesio taping had positive effects on the pain, tenderness, and proprioceptive sensation of delayed onset muscle soreness. These results suggest that Kinesio taping can be a useful therapeutic factor in future studies and in clinical settings.

Objectives: The study investigated the efficacy of oral Korean red-ginseng (RG) on sCRP response mediated by eccentric contraction-induced muscle damage and discussed its mechanism. Methods: Nineteen healthy young subjects (aged 24.4$\pm$2.07 yr) volunteered for this double blind test. They were classified into either the RG group (N=10) or placebo (P) group (N=9) during the 10-d experimental protocol. Blood samples were collected on T1 (baseline), T1 (1h), T2 (1d), T3 (2d) and T4 (3d) after eccentric contraction-induced injury on the seventh day. Statistical analyses were conducted using nonparametric methods (p<0.05). Results: The RG group increased sCRP more than P group and didn't increase soreness peak at T2, not significant. There were no correlations between soreness intensity and sCRP. Oral RG had little efficacy for reducing sCRP at the muscle damage-mediated acute phase; rather, it increased because of its proinflammatory cytokine production. Conclusions: Oral RG could stimulate proinflammatory cytokine production, and occasionally bal-pyo-beob could be helpful for the efficient recovery of muscle injury.

This study was conducted to investigate the relationship between ACE gene polymorphism and muscle damage parameters after eccentric exercise. 80 collegiate males were instructed to take an eccentric exercise with the elbow flexor muscle through the modified preacher curl machine for 2 sets of 25 cycles (total 50 cycles). The maximal isometric strength, muscle soreness, creatine kinase (CK), and myoglobin (Mb) were measured before exercise, and 0, 24, 48, 72, and 96 hrs after exercise. The result showed that after the eccentric exercise, the maximal isometric strength significantly decreased by more than 50% (p < 0.001) and the muscle soreness, CK, and Mb significantly increased compared to those before the exercise (p < 0.001). The ACE gene polymorphism of the subjects was classified using real-time polymerase chain reaction (real-time PCR). The result showed that it consisted of 38 cases of type II (46.4%), 33 cases of type ID (43.4%), and 9 cases of type DD (10.2%). The Hardy-Weinberg equilibrium for ACE gene polymorphism was shown to have p = 0.653, which showed that each allele was evenly distributed. Although significant differences in the changes in the maximal isometric strength, muscle soreness, CK, and Mb were found according to time course (p < 0.001), no significant differences in the changes in the maximal isometric strength, muscle soreness, CK, and Mb were found according to ACE gene polymorphism. Furthermore, no significant difference in the changes in the muscle damage parameters was found according to interaction between ACE gene polymorphism and time course (p > 0.05). In conclusion, the level of the muscle damage parameters changed in the injured muscle after eccentric exercise, but these changes in the muscle damage parameters were not affected by ACE gene polymorphism. The result of this study indicates that ACE gene is not a candidate gene that explains muscle damage.

This study was designed to investigate the effect of vibratory stimulation on recovery of muscle function from delayed onset muscle soreness (DOMS). Volunteers performed 3 set of 70 % maximal voluntary eccentric muscle contraction and induced DOMS. volunteers were allocated to one of three treatment group after DOMS : group I (control), group II (ultrasound), group III (vibration). Maximal Voluntary Isometric Contraction (MVIC), Visual Analog Scale (VAS), Range Of Motion (ROM), Root Mean Square (RMS), Median frequency (MDF), Blood Serum Creatine Kinase (CK), Lactic dehydrogenase (LDH) were recorded at baseline, and 24, 48, 72 hours post-exercise. In MVIC measurement, there was a statistically significant difference in group III compared to group I (p < .05). In VAS measurements, there were a statistically significant difference in group II and III compared to group I (p < .05). In ROM measurement, there was a statistically difference in group II and III compared to group I (p < .05). In Muscle Volume with Ultrasonography measurement, there was no statistically significant difference in any groups (p > .05). In RMS and MDF measurement, there were a statistically significant difference in group II and III compared to group I (p < .05). In Blood samples of CK and LDH measurements, There were no statistically significant difference in any groups (p > .05). From the above result, Vibratory stimulation had a positive effect on recovery of muscle function from delayed onset muscle soreness. Further studies should be undertaken to ascertain the more effectiveness of vibratory stimulation and may be a promising treatment modality.

Purpose : The purpose of this study was to determine the effects of specific frequency and application timing of microcurrent (MC) on the mechanical property of muscle caused by delayed onset muscle soreness (DOMS). Methods : The subjects were 32 healthy adults with 8 subjects randomly assigned to four groups (I; 40 Hz MC while inducing DOMS, II; 40 Hz MC immediately after inducing DOMS, III; 284 Hz MC while inducing DOMS, IV; 284 Hz MC immediately after inducing DOMS). DOMS is applied to the biceps brachii muscle while MC was applied at an intensity of $300{\mu}A$ for 10 minutes. The mechanical properties of muscle were measured before and immediately after DOMS. Results : In terms of muscle tone, there were significant differences in interaction effects between time and groups. Regarding muscle elasticity and stiffness, there were no significant differences in interaction effects between time and groups but there were only significant differences in main effects based on time. Conclusion : The results indicated that 40 Hz MC had an effect on reducing muscle tone regardless of application timing. However, both 40 Hz and 284 Hz MC did not trigger changes in muscle elasticity and stiffness regardless of application timing.

Objectives : The aim of this study was to investigate difference of the effects of transcutaneous electrical nerve stimulation(TENS) with different frequencies in participants having delayed onset muscle soreness(DOMS). Methods : We recruited 36 healthy participants, but 3 of them were dropped out. They were randomly divided into 3groups : 3 Hz TENS(n=11), 100 Hz TENS(n=11) and sham TENS(n=11). DOMS of the both triceps surae muscle induced by repetitive concentric, ecentric exercise. The result measurements were pain perception(visual analogue scale, VAS), mechanical pain threshold(MPT) by pressure algometer, electrical contraction and fatigue by surface electromyography. The measurements were on first visit, before and after treatment except first. This study was prospective, randomized, controlled, single-blinded trial. Results : In 100 Hz TENS group, VAS was significantly decreased during whole session compared with 3 Hz and control group, and after each treatment, too. In 3 Hz TENS group, VAS was significantly decreased during whole session compared with control group, and after 2nd, 3rd treatment, too. In 100 Hz TENS group, MPT increased the most among 3 groups during whole session and after 1st treatment, but there were no statistical significances. Conclusions : Both 3 Hz and 100 Hz TENS improved delayed onset muscle soreness, but 100 Hz TENS group is more effective than 3 Hz TENS group.

[Purpose] This study aimed to investigate the effects of leucine-enriched essential amino acid (LEAA) supplementation on muscle fatigue and the level of inflammatory cytokines in wheelchair basketball players after a basketball game and interval training. [Methods] Of the ten recruited wheelchair basketball players (aged 34.5±8.9 years; lean body mass of 34.3±10.0 kg) who had spinal cord injury (SCI) and had undergone amputation, nine participated in the final test. These nine athletes received LEAA supplements (3 times 4.0 g/day) or placebo treatment in a double-blind, randomized, crossover study. We measured variables related to muscular fatigue and inflammatory response before the intense exercise and 4 days after recovery. [Results] The significant effect of LEAA supplementation was inhibition of circulating IL-6 levels in the LEAA-treated group compared with the placebo group (P < .05). However, no changes were observed in the TNF-α and creatinine kinase levels. Moreover, analysis of variance analysis showed no significant difference in the relative values of muscle soreness. However, the effect size analysis with Cohen's d reported a significant improvement in the relative values of whole body and back muscle soreness. [Conclusion] Our results revealed that LEAA supplementation before and after intense exercise could help reduce muscle soreness and IL-6 levels in wheelchair basketball players.

[Purpose] In this literature review we aimed to investigate the effects of curcumin supplementation on delayed onset muscle soreness (DOMS), which occurs after exercise, and evaluate related parameters to propose practical recommendations for the field of exercise physiology. [Methods] Experimental studies conducted on curcumin supplementation and DOMS were systematically reviewed to determine (1) the effect of curcumin supplementation on DOMS, (2) potential mechanisms by which curcumin supplementation may attenuate DOMS, and (3) practical considerations for curcumin supplementation. [Results] While several studies have reported that curcumin supplementation attenuates DOMS after exercise, others have reported that curcumin supplementation has no effect on DOMS. Several mechanisms have been proposed by which curcumin supplementation may attenuate DOMS; the most probable of which is a reduction in inflammatory response. Other potential mechanisms include modulation of transient receptor potential vanilloid 1 (TRPV1) or changes in post-exercise capillary lactate levels; these require further examination. The usual recommended dose of curcumin is 150-1500 mg daily (sometimes up to 5 g), divided into 2-3 portions and taken before and after exercise. It is not necessary to take curcumin together with piperine. [Conclusion] Although conflicting results regarding the effects of curcumin supplementation on DOMS exist in literature, it may be considered as a method of nutritional intervention for reducing post-exercise DOMS.
