The Difference

Although delayed onset muscle soreness and increased serum creatine kinase activity (SCKA) following unaccustomed exercise is common in adults, little is known concerning these responses in children. The perception of muscle soreness and SCKA in children (n = 16) (M age = 10.4±.30 yr) was compared to a control group of adults (n = 15) (M age = 27.1±.87 yr) following a single bout of downhill running (30 min − 10% grade). Preexercise SCKA was not significantly different between the children (91.7±8.5 μmol•L−1•min−1) and the adults (77.1±5.9 μmol•L−1•min−1). The difference in SCKA (pre to 24 hours post) was significantly less (p<.01) for the children (68.6±16.2 μmol•L−1•min−1) than for the adults (188.7±36.8 μmol•L−1•min−1). When the groups were adjusted for weight differences, SCKA was not significantly different between the adults and the children. Regardless of age, males demonstrated a significantly greater increase in SCKA postexercise when compared to females. Soreness ratings (verbally anchored scale from 1 to 10) 24 hours following the downhill run were not significantly different between the children (3.8±.6) and the adults (4.5±.7). Following an eccentrically biased exercise task, children exhibited less of a SCKA response compared to adults that is related to body weight.

The purpose of this study was to determine the effects of acupuncture on delayed onset muscle soreness (DOMS) produced by exercise. Baseline data were collected on 20 male subjects for intensity of muscle soreness and serum creatine kinase (CK) activity. All values were subsequently reassessed 24, 48 and 72 hours after exercise. The experimental group received acupuncture treatment while the control group received no treatment. Muscle soreness perception was significantly less (P < 0.05) at 72 hours in the acupuncture treated group compared to control group. However, the change in CK was not significantly different between groups. These results suggest that acupuncture is effective in decreasing muscle soreness but does not prevent CK release from muscle.

Low Intensity

This study investigated the magnitude and duration of the protective effect of low-intensity eccentric contractions (LowEC) against damage induced by maximal eccentric contractions (MaxEC) of the knee flexors (KF) and extensors (KE). Young men were assigned to 8 experimental groups and 2 control groups (n = 13/group); the experimental groups performed LowEC of KF or KE 2 days (2d), 1 week (1wk), 2 weeks (2wk), or 3 weeks (3wk) before MaxEC, while the control groups performed MaxEC of KF or KE without LowEC. The 2d, 1wk, 2wk, and 3wk groups performed 30 LowEC of KF or 60 LowEC of KE with a load of 10% of maximal voluntary isometric contraction strength on a resistance-training machine, and all groups performed 30 MaxEC of KF or 60 MaxEC of KE on an isokinetic dynamometer. Several muscle damage markers were measured from before to 2 days after exercise (LowEC) or from before to 5 days after exercise (MaxEC). No significant changes in any variables were evident after LowEC. The changes in all variables after MaxEC were smaller (P < 0.05) for the 2d and 1wk groups (e.g., peak creatine kinase activity: 1002 ± 501 IU/L; peak muscle soreness: 13 ± 5 mm) than for the control group (peak creatine kinase activity: 3005 ± 983 IU/L; peak muscle soreness 28 ± 6 mm) for both KE and KF. There were no significant differences between the 2d and 1wk groups or among the 2wk, 3wk, and control groups. These results show that LowEC provided 30%–66% protection against damage induced by MaxEC of KF and KE, and the protective effect lasted 1 week.

Kinesiology Tape

Background: Delayed-onset muscle soreness (DOMS) causes muscle damage and edema that can hinder performance and increase risks for secondary injuries. Kinesiology Tape (KT) may be an effective modality for aiding in recovery, however, no study has investigated the effects of KT on the physiological biomarkers such as serum creatine kinase (CK) level, concurrently with measures of performance and function, during recovery from DOMS. Objective: Investigate the effects of KT on serum CK level, electromyographic (EMG) activity of the quadriceps muscles, and performances of countermovement jump (CMJ) and triple single-leg hop for distance (HopD) during recovery from DOMS. Method: Fifty-eight healthy college-age participants were randomly assigned to KT (n=15), placebo (n=19), and control (n=24) groups. Serum CK level and quadriceps EMG activity and performance during CMJ and HopD were collected at baseline, immediately after repetitive eccentric quadriceps exercise, 48 hours, and 72 hours post-exercise. The EMG recording of rectus femoris, vastus medialis, and vastus lateralis during the CMJ and HopD were normalized to the baseline maximum voluntary isometric contraction. Results: A significant main effect of time on the serum CK level, EMG activity, and performance (p<0.05) was observed. However, there were no group differences on the serum CK level, EMG activity, or performance (p>0.05). Conclusion: Taping interventions did not improve the serum CK level or muscle activity and performance during recovery from DOMS. Kinesiology tape may not be the first choice of method for enhancing recovery from DOMS in otherwise healthy individuals.
