Effectiveness analysis of muscle stretching during interferential current in soccer players: an explorative study

Aim of this explorative study is to determine the feasibility of muscle stretching during interferential current therapy (ICT) versus no stretching on hamstring extensibility and evaluate acute effects. It should generate hypothesis for further empirical studies. 12 amateur soccer players were included. Interventions: Hamstring stretching during ICT vs. rested. Main Outcome Measure was Fingertip-to-floor test (FTF) and was measured at baseline, 15, 45 and 90 minutes after intervention. Hamstring extensibility increased significantly in both groups with a median of 8.20 cm after 90 minutes in the IG compared to 5.90 cm in the CG. Hamstring extensibility could increase during ICT. However, the
selection of the measurement method FTF should be reconsidered and for further research a sensitive and valid measurement tool should be selected.
