title: Kinesiotaping enhances the rate of force development but not the neuromuscular efficiency of physically active young men.
abstract: BACKGROUND
  Investigations on the effects of KT on human performance have been increasing in the last few years. However, there is a paucity of studies investigating its effects on neuromuscular efficiency (NME) and rate of force development (RFD).
  
  
  OBJECTIVE
  To evaluate the NME and RFD of the soleus and gastrocnemius muscles in physically active individuals under KT application.
  
  
  METHODS
  Twenty young males (79.7±8.2kg; 1.78±0.05m; 24.7±4.4years) performed three conditions in a randomized order: (1) Baseline (BL, no tape); (2) Activation (ACTIKT, tape for muscle activation); and (3) Inhibition (INHIKT, tape for muscle inhibition). The tape was applied along the lateral and medial border of gastrocnemius with 30% tension for 48h. Peak torque (PT), RFD and NME were measured at BL and 48h after ACTIKT and INHIKT by performing a maximum isometric contraction.
  
  
  RESULTS
  The RFD was significantly higher in ACTIKT compared to BL at 0-30 (P=0.010), 0-50 (P=0.008) and 0-100ms (P=0.007). The PT and NME did not differ among conditions (P>0.05).
  
  
  CONCLUSIONS
  KT applied for muscle activation yielded a higher RFD during the initial phase of the muscle contraction. However, KT has no enhancement effect on NME and peak torque.
