Comparison Interventions on Kinetic and Kinematic Parameters

Currently, it is difficult to find studies in the literature comparing proprioception exercises with the effect of manual therapy on improving balance, and in the long run it may translate into improved activity, functionality and injury prevention in athletes, when planning training or therapy, e.g. in patients after ankle sprains.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age 11-13 years
  • Male
  • Minimum 2 years of experience in soccer coaching
  • Participation in regular club training (at least 3 times a week)
  • Parental/legal guardian consent and participant consent to participate in the study
  • No medical contraindications to physical activity

Exclusion criteria

Treatment and study plan

Manual therapy

Other

This technique involves mobilizing the upper ankle joints by mobilizing the talus and calcaneus, improving pronation.

Placebo

Other

The players will perform their own type of pro-receptive training.

Exercise

Other

Pro-receptive training will be performed.

Primary outcomes

  1. Y balance test

    Time frame: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.

    Consists of the volunteer standing on one leg while simultaneously stretching the other lower limb in 3 different directions. These are: anterior, posteromedial and posterolateral.

  2. 1. Balance

    Time frame: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.

    K-FORCE plates assess balance characteristics during testing.

Secondary outcomes

  1. Assessment of proprioception.

    Time frame: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.

    The proprioception assessment involves assessing the angular position of the joint and then attempting to reproduce it, measured in degrees. The assessment will be conducted at 30 degrees, 60 degrees, and 90 degrees.

  2. Muscle strength assessment

    Time frame: The test will be administered twice during a single training session. Baseline (0 minutes before the intervention) and immediately post-intervention (within 5 minutes after completion of the training session). Each test will be repeated three times.

    The K-FORCE Push Test allows you to assess your strength characteristics during the hip abduction test.
