Fitness Field Tests' Correlation With Game Performance in U-19-Category Basketball Referees.

Purpose: To examine the relation between game performance, physiological responses, and field-test results in Tunisian basketball referees.

Methods: Computerized time-motion analysis, heart rate (HR), and blood lactate concentration [La] were measured in 15 referees during 8 competitive games (under-19-y-old Tunisian league). Referees also performed a repeated-sprint test (RSA), Yo-Yo Intermittent Recovery Test level 1 (YYIRTL1), agility T-test, and 30-m sprint with 10-m lap time.

Physical and physiological demands of U-19 basketball refereeing: Aerobic and anaerobic demands.

Objectives: This study aimed to examine the physical and physiological demands of basketball refereeing.

Methods: 16 elite-level basketball referees were studied during U-19 basketball games (n=8) for time-motion analyses, exercise heart rates (HR) and blood lactate concentration [La]. Game activities were considered as time spent and distance covered in five locomotors activities (standing, walking, jogging, running and sprinting).
