The Physical and Physiological Demands of Basketball Training and Competition

TLDR

The study aims to characterize the physical and physiological responses of male basketball players during various practice drills and competitive games. Heart rate, VO₂, and triaxial accelerometer data were collected from 11 male players during offensive/defensive drills, half‑court scrimmages, and games, normalized for participation time, log‑transformed, and analyzed using effect‑size statistics. Offensive and defensive drills produced similar physical and physiological loads, whereas live play was substantially more demanding than a 5‑on‑5 scrimmage, with higher physical load, mean heart rate, and oxygen demand, indicating that accelerometers and heart‑rate monitoring can differentiate practice from competition demands.

Abstract

To characterize the physical and physiological responses during different basketball practice drills and games.Male basketball players (n=11; 19.1+/-2.1 y, 1.91+/-0.09 m, 87.9+/-15.1 kg; mean+/-SD) completed offensive and defensive practice drills, half court 5on5 scrimmage play, and competitive games. Heart rate, VO2, and triaxial accelerometer data (physical demand) were normalized for individual participation time. Data were log-transformed and differences between drills and games standardized for interpretation of magnitudes and reported with the effect size (ES) statistic.There was no substantial difference in the physical or physiological variables between offensive and defensive drills; physical load (9.5%; 90% confidence limits+/-45); mean heart rate (-2.4%; +/-4.2); peak heart rate (-0.9%; +/-3.4); and VO2 (-5.7%; +/-9.1). Physical load was moderately greater in game play compared with a 5on5 scrimmage (85.2%; +/-40.5); with a higher mean heart rate (12.4%; +/-5.4). The oxygen demand for live play was substantially larger than 5on5 (30.6%; +/-15.6).Defensive and offensive drills during basketball practice have similar physiological responses and physical demand. Live play is substantially more demanding than a 5on5 scrimmage in both physical and physiological attributes. Accelerometers and predicted oxygen cost from heart rate monitoring systems are useful for differentiating the practice and competition demands of basketball.
