简要总结
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.
详细描述
Twenty participants were included in the study. All participants were divided in two groups - control and experimental. In the experimental group (n=10) participants after team soccer training additional received 4 weeks eccentric exercises, in the control group (n=10) - did not perform additional exercises. The research group performed additional low-load and high-velocity - lying prone - eccentric hamstring exercise 3 times per week for 4 weeks. Pre- and post- training assessment included concentric/eccentric knee extension and flexion at 60°/s and 120°/s, changes in muscle contractile characteristics and dynamic balance.

结局指标
主要结局
Dynamic balance
时间窗: Baseline and after 4 weeks
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.
Changes in isokinetic peak torque (with Biodex)
时间窗: Baseline and after 4 weeks
Knee extension/flexion isokinetic peak torque measurements will be done at 60°/s, 120°/s
Changes in muscle contractile characteristics (with tensiomyography (TMG))
时间窗: Baseline and after 4 weeks
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.
