Relationship of Anthropometric Profile and Fitness Indicators With Sports Performance of Elite Mexican National Team Soccer Players

"According to the International Society for the Advancement of Kinanthropometry (ISAK) standards, sixteen anthropometric variables have been assessed to characterize the athlete's anthropometric profile. The counter-movement jump assessments were conducted using a ForceDecks Max platform. During matches, the players' GPS-derived external Load Metrics were monitored using 18 Hz WIMU Pro GPS units. Normality tests of all variables will be performed.~Certificated anthropometrists performed the anthropometric assessment twice. A third measurement will be performed if the difference between these measures exceeds 5% for skinfolds and 1% for all other variables. Countermovement jump tests were conducted in duplicate, and the higher measurements were recorded. In-match GPS-derived external load metrics of different matches will be downloaded and analyzed."
