Cell culture-induced aberrant methylation of the imprinted IG DMR in human lymphoblastoid cell lines.

OBJECTIVES

To investigate the prophylactic effect of the active isolated stretching technique on exercise-induced muscle damage of wrist flexors.

METHODS

The mixed model randomised controlled interventional study was conducted at the University of Sargodha, Sargodha, Pakistan, from November 2018 to May 2019, and comprised young adults who were untrained, sedentary and healthy who were randomly divided into intervention group A and control group B. Group A participants received self-assisted active isolated stretching before inducing muscle soreness of wrist flexors by eccentric exercises. Group B did not receive any intervention. The outcome measures were pain intensity, muscle soreness, pressure pain threshold, range of motion, and grip strength. Data were collected at baseline, after one hour, and daily from day 1 to 7 after inducing muscle soreness. Data were analysed using SPSS 21.

RESULTS

Of the 60 subjects, there were 30(50%) in each of the two groups. There were 14(23.3%) males and 46(76.7%) females. The overall mean age was 21.47±1.9 years. Group A showed early recovery in pain and muscle soreness compared to group B (p<0.05). Also, a limited deficit in the range of motion, grip strength, and pain pressure threshold was found in group A compared to group B (p<0.05).

CONCLUSIONS

Active isolated stretching before strenuous, unaccustomed exercise was found to be useful in ameliorating the symptoms of muscle soreness.
