Introduction:

Referees play a fundamental and determining role within the soccer competitive game system. Identifying the relationship between changes in anthropometric composition in relation to nutritional status could improve the understanding of referees' performance.

Objective:

To determine the influence of the body mass index (BMI) on the footprint of soccer referees.

Methods:

An exploratory-correlational study with quantitative analysis was carried out in 28 male referees aging 22.43 ± 3.30 years who made up the sample. Information on height and weight was collected, to determine their body mass index (BMI). In addition, information was collected for the plantar footprint from the indicators of forefoot width (X), midfoot width (Y), complementary width (AY), hindfoot width (AT), footprint index (% X) and foot length (LP) on both feet. The correlation coefficient analysis was carried out in PSPP (p-value of 0.05).

Results:

The average BMI of the participants in this study was normal and the classification of the type of foot was normal / cavus for both. On the other hand, the BMI has significant correlation with X (r = 0.50; p = 0.01) and AT (r = 0.46; p = 0.01) of the left foot, while the BMI and X obtained a very significant relationship (r = 0.59; p = 0), and was significantly related (r = 0.39; p = 0.04) as well as AT (r = 0.40; p = 0, 04).

Conclusions:

BMI is considered to affect the footprint of soccer referees.
