• Study Type: interventional
• Target: 20

Brief Summary

A randomized controlled trial is designed to examine the effects of low-load and high-velocity eccentric exercises on lower limb muscular properties, imbalances and functional status of 13-15 years old female football players.

Conditions

Healthy

Keywords

Young age soccer player; Eccentric hamstring exercise; Dynamic balance; Contractile muscle properties

Outcome Measures

Primary Outcomes (3)

• Changes in isokinetic peak torque (with Biodex)

  Knee extension/flexion isokinetic peak torque measurements will be done at 60°/s, 120°/s

  Baseline and after 4 weeks

• Dynamic balance

  Y-balance Test evaluates lower extremity strength, knee stability and dynamic balance in anterior, posteromedial and posterolateral direction. For each direction, three practice trials were allowed before three test trials were recorded. Mean reach distances (cm) was normalized to leg length, which was measured from the anterior superior iliac spine to the most distal portion of the medial malleolus.

  Baseline and after 4 weeks

• Changes in muscle contractile characteristics (with tensiomyography (TMG))

  Muscle involuntary contractile characteristics of the lower-limb muscles-the rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), semitendinosus (ST), tibialis anterior (TA), gastrocnemius medialis (GM) and gastrocnemius lateralis (GL)-will be recorded by measuring the response of these muscles to an induced electric stimulus (provoked by two self-adhesive electrodes) using TMG equipment on both the left and right lower extremities.

  Baseline and after 4 weeks
