title: Effect of scraping therapy on weightlifting ability.
abstract: OBJECTIVE
  To verify the effects of scraping therapy on the weightlifting ability by measuring the subjective sensation, and changes of biomarkers.
  
  
  METHODS
  Five students, who have been trained for 3 years in a sport school in China were participated in this study. A course of scraping therapy was applied to intervene during the normal 7-week of weightlifting training programme. The ability of weightlifting, the scale of rating perceived exertion and serum biochemical markers were measured before and after the intervention.
  
  
  RESULTS
  Scraping therapy caused a significant increase in weightlifting ability (P < 0.05). The level of rating perceived exertion remained stable with the increase in the training volume. Immuno-globulin A was significantly increased (P < 0.05), and creatine kinase and blood urea nitrogen were significantly decreased (P < 0.05). No significant changes were observed in white blood cell, neutrophil, and testosterone.
  
  
  CONCLUSIONS
  Scraping therapy may facilitate weightlifting ability mainly by decreasing weight sensation and improving serum biochemical parameters.
