Three-by-Three Basketball: Inertial Movement and Physiological Demands During Elite Games

Area of Science:

• Sports Science
• Biomechanics
• Physiology

Background:

• 3x3 basketball is a rapidly growing Olympic sport.
• Understanding the game's physical demands is crucial for athlete development and training.
• Limited research exists on the specific demands across different elite competition levels.

Purpose of the Study:

• To quantify the physical and physiological demands of elite male and female 3x3 basketball games.
• To compare these game demands across various international competition levels (U18 World, European, World Championships, professional tournaments).

Main Methods:

• Utilized wearable technology (GPS, inertial measurement, heart rate) to assess game demands in 361 males and 208 females.
• Collected postgame blood lactate and rating of perceived exertion data.
• Employed magnitude-based inferences to compare differences in game demands and physiological responses.

Main Results:

• PlayerLoad and PlayerLoad per minute showed minimal differences between junior, senior, and professional levels for both genders.
• Small differences in accelerations and decelerations were observed between competition levels, with European Championships showing higher values.
• Average heart rate and rating of perceived exertion were consistently high, indicating significant physiological strain, with no substantial differences across levels.

Conclusions:

• 3x3 basketball necessitates intense, high-speed inertial movements over short distances, resulting in substantial physiological stress.
• Coaches and practitioners should prioritize developing specific player attributes that enhance performance in these demanding conditions.
• The findings provide valuable insights for optimizing training programs for elite 3x3 basketball players.
