AB  - The aim of this study was to investigate mechanical sensitivity responses at the 
      lateral elbow to repeated weekly bouts of low load exercise in healthy subjects. 
      Thirteen young men (n=6) and women participated in 4 weeks of exercise. Arms were 
      randomly allocated to an eccentric-only exercise protocol (ECC: 5 sets of 20 
      contractions) or to a concentric-eccentric protocol (CON-ECC: 5 sets of 10 
      eccentric/10 concentric contractions) performed at 30% maximal wrist extension 
      force. Arms were exercised consecutively within each supervised weekly session. 
      Quantitative measures of pressure pain threshold (PPT) recorded at three sites 
      and maximal force for grip and wrist extension were assessed at baseline, and 
      immediately pre/post exercise at each session. Muscle endurance during 100 
      maximal grip contractions force was assessed at baseline and one week following 
      the final exercise session. Results showed that regardless of protocol, repeated 
      low load exercise resulted in a time-dependent increase in PPT at all sites post 
      exercise Weeks 3 and 4 and persisting at follow up Week 5 (P<0.02). No 
      significant difference between protocols was evident for any measure. Muscle 
      force and endurance were not significantly augmented compared with baseline. In 
      conclusion mechanical hypoalgesia is induced by repeated low load exercises 
      regardless of exercise mode, and this may prove beneficial if replicated 
      clinically.
