Nutritional Attitudes and Anthropometric Measurements in Relation to Agility in Football Players

Soccer players' agility can be affected by many factors, including nutrition and body composition. The primary objective of our study is to reveal the relationship between nutritional attitudes and anthropometric measurements and agility in elite adolescent soccer players. Our secondary objective is to determine the effect of daily fluid intake and daily sleep duration on anthropometric measurements, nutrition attitude scores, and agility in soccer players. Study was conducted on 51 male soccer players aged 14-18. Information on the soccer players' sociodemographic characteristics and lifestyles was obtained via a questionnaire. Body composition analysis was measured using a Bioelectrical Impedance Analysis (BIA) device, and hand grip strength was measured using a hand grip dynamometer. Height, waist circumference, and hip circumference were measured. Soccer players' attitudes toward nutrition were assessed using the Nutrition Attitude Scale (NAS), and their agility was assessed using the Agility T-Test.

About this study

This descriptive cross-sectional study was conducted between January 15 and March 1, 2024, with adolescent football players from the Tümosan Konyaspor Football Club. Sample size calculation was performed using G*Power 3.1.9.4 based on a correlation coefficient of 0.35, 95% power, and a 0.05 alpha level, resulting in a minimum required sample size of 41 participants. A total of 51 male football players aged 14-18 years were included.

Data were collected through face-to-face interviews using a structured questionnaire comprising sociodemographic and lifestyle characteristics, anthropometric measurements, agility assessment, and the Nutrition Attitude Scale (NAS). Anthropometric measurements and body composition parameters were assessed using bioelectrical impedance analysis, while height, waist and hip circumferences, and hand grip strength were measured using standardized procedures. Nutritional attitudes were evaluated with the NAS. Agility performance was assessed using the Agility T-test with electronic timing.

Statistical analyses were performed using SPSS version 22.0. Descriptive statistics were calculated, normality was assessed, and appropriate parametric and non-parametric tests were applied. Relationships between variables were examined using Pearson correlation analysis, with statistical significance set at p < 0.05.

Treatment and study plan

Primary outcomes

  1. Sociodemographic and lifestyle information

    Time frame: Baseline (single assessment).

    Sociodemographic and lifestyle information, including age, education level, disease status, smoking and alcohol use, fluid consumption, and sleep duration, will be collected using a structured questionnaire and reported descriptively as a single composite dataset.Unit of Measure:

    Composite descriptive variables

  2. Hand grip strength

    Time frame: Baseline (single assessment).

    Hand grip strength was measured using a TAKEI T.K.K 5401 (Japan) brand hand grip dynamometer. During the measurement, the football players were asked to sit down with their elbows bent to the side at a 90° angle and squeeze the tool with all the hand strength they could (Massy-Westropp et al., 2011). Each hand grip strength trial lasted at least 4 seconds, with a 20-second rest period between trials (Valenzuela et al., 2020). Hand grip strength measurement was repeated twice on the right and left hands, and the highest measurements for each hand were determined and averaged to calculate hand grip strength.

  3. Agility assessment

    Time frame: Baseline (single assessment).

    The agility assessment was performed by the researcher physiotherapist. The agility T-test is a running test in which four cones are arranged in a T-shape. Three cones were placed 4.57 m apart in a straight line, with the starting cone 9.14 m away, lying perpendicular to the middle cone. Football players were asked to accelerate to touch the base of each cone and to run forward, laterally, and backward between the cones as fast as possible. An electronic timer was used to record times in the test

Secondary outcomes

  1. Body Fat Mass

    Time frame: Baseline (single assessment).

    Body fat mass was measured using a TANITA BC-418 MA (Tokyo, Japan) Bioelectrical Impedance Analysis (BIA) device with a sensitivity of 0.1 kg.

  2. Body Weight

    Time frame: Baseline (single assessment)

    Body weight was measured using a calibrated scale.

  3. Nutritional attitudes

    Time frame: Baseline (single assessment)

    Nutrition Attitude Scale. This scale, applied to high school and university students aged 12-25, assesses individuals' attitudes toward nutrition in relation to their consumption of processed foods, carbohydrates, vitamins, minerals, protein, and water

  4. Body Muscle Mass

    Time frame: Baseline (single assessment)

    Body muscle mass was measured using a TANITA BC-418 MA (Tokyo, Japan) Bioelectrical Impedance Analysis (BIA) device with a sensitivity of 0.1 kg.

  5. Body Water Mass

    Time frame: Baseline (single assessment)

    Body water mass was measured using a TANITA BC-418 MA (Tokyo, Japan) Bioelectrical Impedance Analysis (BIA) device with a sensitivity of 0.1 kg.

  6. Body Mass Index (BMI)

    Time frame: Baseline (single assessment)

    Body mass index was calculated by dividing body weight (kg) by the square of height (m²).

  7. Waist Circumference

    Time frame: Baseline (single assessment)

    Waist circumference was measured using a non-elastic measuring tape.

  8. Hip Circumference

    Time frame: Baseline (single assessment)

    Hip circumference was measured using a non-elastic measuring tape.Unit of Measure: cm
