Conventional icing studies outcome variables and results

StudyOutcome variablesResults
Fischer et al 39 Shuttle run, co-contraction test and vertical jumpPower (vertical jump) was impaired immediately and 20 min after 10 min ice bag application to the hamstrings, whereas a shorter duration of ice application had no effect on these tasks.Functional performance (shuttle run and co-contraction test) was impaired immediately and 20 min after 10 min ice bag application to the hamstrings, whereas a shorter duration of ice application had no effect on these tasks.
Lee et al 44 CMJ or SJ heightCMJ height decreased immediately after ankle and knee cryotherapy, no change was seen in the rest group. CMJ height returned to baseline 10 min after CT.No changes in SJ height were noted in CT or rest group.
Behringer et al 42 CK, h-FABP, DOMSNo difference in DOMS was observed between MLD, icing or rest.No difference between biomarkers was observed between MLD, icing or rest.
  • CK, creatine kinase; CMJ, countermovement jump; CT, cryotherapy;  DOMS, delayed onset muscle soreness; h-FABP, fatty acid binding protein; MLD, manual lymphatic drainage; SJ, squat jump.
