Accelerometer Load Profiles for Basketball-Specific Drills in Elite Players

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Background:

• Basketball training involves various drills to enhance player performance.
• Quantifying the physical demands of specific drills is crucial for optimizing training loads.
• Microtechnology offers objective measures of athlete workload.

Purpose of the Study:

• To quantify the workload of professional basketball players during specific drills using microtechnology.
• To compare the physical demands across different basketball drill formats (2v2, 3v3, 4v4, 5v5).
• To evaluate the utility of accelerometer-derived data for assessing training load.

Main Methods:

• Twelve professional male basketball players from the Spanish 1st Division participated.
• Workload was measured using tri-axial accelerometers (100Hz sampling frequency).
• Data were collected over 4 weeks, encompassing 16 sessions and 95 ± 33 drills per player.
• Acceleration Load per minute (AL·min⁻¹) was calculated and compared across drills using standardized mean differences.

Main Results:

• Full-court 3v3 and 5v5 drills exhibited the highest physical demand (AL·min⁻¹: 18.7 ± 4.1 and 17.9 ± 4.6, respectively).
• Traditional drills like 2v2 and 4v4 showed lower demands (AL·min⁻¹: 14.6 ± 2.8 and 13.8 ± 2.5, respectively).
• Half-court drills, particularly 2v2, indicated a likely 10-20% increase in workload compared to other formats.

Conclusions:

• 3v3 and 5v5 full-court drills impose the greatest physical load in professional basketball training.
• Accelerometer-based workload assessment provides valuable, objective insights into basketball drill intensity.
• Understanding drill-specific demands aids in designing more effective and targeted training programs.
