Activity Profiles in International Women's Team Handball Using PlayerLoad

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Background:

• Team handball demands diverse physical efforts, potentially leading to player fatigue and reduced activity.
• Existing speed-based activity quantification methods may not capture handball-specific movements effectively.

Purpose of the Study:

• To investigate the activity profiles of a women's team handball team and individual players.
• To utilize inertial measurement units (IMUs) for detailed player activity analysis.

Main Methods:

• Data collected from 85 player samples across 9 international matches using Catapult OptimEye S5.
• PlayerLoad/min measured intensity over 5- and 10-minute intervals.
• Team and individual profiles analyzed relative to match means and high-field-time periods.

Main Results:

• High initial intensity observed for team and player profiles, especially with consecutive play periods.
• Significant declines in PlayerLoad/min noted throughout matches for the team and players.
• Intensity peaked in the final 5 minutes of the first half; activity decreased post-intense periods with partial restoration.

Conclusions:

• Observed activity declines may stem from fatigue, situational factors, or pacing strategies.
• Underlying mechanisms require further investigation, building on previous team-sport research.
