Comparison of Balance, Core Stabilization Performance, Foot Reaction Time and Body Awareness in Young Amateur Football Players From Different Age Groups

July 27, 2026 updated by: Ezgi Türkmen, Health Institutes of Turkey
Aim of the study is to compare balance, core stabilization performance, foot reaction time, and body awareness in 50 amateur football players aged 13-19 (Group I: 13-15 years, and Group II: 16-19 years) according to age, and to determine age-related performance differences.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The aim of this study is to evaluate balance, core stabilization performance, foot reaction time and body awareness in amateur football players aged 13-19 years, to examine how these parameters change according to age groups, and to compare and reveal developmental differences in these performance components in young athletes. This research study is designed as an observational and cross-sectional evaluation study. The study aims to collect and compare the data according to age on participants' sociodemographic data, balance status using the Y-Balance Test, endurance levels using the McGill Core Endurance Test, reaction time using the Nelson Foot Reaction Test, and awareness levels using the Body Awareness Questionnaire.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Nelson Foot Reaction Test
Time Frame: Baseline
The Nelson Foot Reaction Test measures simple foot-eye reaction time and lower limb neuromuscular coordination. Using a drop ruler, it requires the subject to quickly stop or "trap" a falling measurement stick between their foot and a wall or the floor in response to an auditory or visual trigger. The Reaction: The subject reacts as quickly as possible, pressing their foot forward to pinch/stop the falling ruler against the wall.Recording: The point where the ruler is stopped indicates the distance it traveled. The reaction time is calculated using the formula: Reaction Time (seconds) = √2 * Distance (cm)/980.
Baseline
Body Awareness Questionnaire (BAQ)
Time Frame: Baseline
BAQ is an 18-item self-report scale designed to measure how attentive you are to normal, non-emotional internal bodily processes. It evaluates your sensitivity to everyday bodily cycles (like sleep and hunger), ability to detect subtle changes, and capacity to anticipate physical reactions. Typically takes about 3 to 5 minutes. Items are generally rated on a 1 to 7 scale, with higher total scores indicating greater perceived confidence and accuracy in monitoring your physical state over time.
Baseline
Y Balance Test (YBT)
Time Frame: Baseline
The YBT requires the athlete to balance on one leg whilst simultaneously reaching as far as possible with the other leg in three separate directions: anterior, posterolateral, and posteromedial. Therefore, this test measures the athlete's strength, stability and balance in various directions. The YBT composite score is calculated by summing the three reach directions and normalising the results to the lower limb length.
Baseline
McGill Core Endurance Test
Time Frame: Baseline
This test measures the stabilization capacity and muscle endurance of the core muscles (abdominal, back, oblique, and lower back muscles). It is performed in four positions: Trunk Flexor Test, Trunk Extensor Test (Sorensen Test), Side Bridge Test (Left & Right). The time (in seconds) spent maintaining the required positions is measured and recorded using a stopwatch.
Baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
