Differences in 200-m sprint running performance between outdoor and indoor venues

Area of Science:

• Sports Science
• Athletic Performance Analysis
• Biomechanics

Background:

• Athletes' 200-m race times are consistently slower in indoor competitions compared to outdoor events.
• Understanding the specific race segments contributing to this performance disparity is crucial for training and strategy.
• Limited data exists on split-time differences in elite-level indoor versus outdoor 200-m sprints.

Purpose of the Study:

• To identify which 50-m sections of a 200-m sprint are slower indoors compared to outdoors.
• To quantify the magnitude of these time differences in elite male and female athletes.
• To explore potential biomechanical factors influencing indoor sprint performance.

Main Methods:

• Utilized 2-dimensional photogrammetric techniques for precise performance analysis.
• Conducted a 50-m split-time analysis on 17 male and 16 female athletes.
• Collected data from 4 national competitions spanning 5 years to ensure robust sample size.

Main Results:

• Both male and female athletes exhibited significantly slower times in the 0-50m and 100-150m sections indoors compared to outdoors (p < 0.05 and p < 0.01, respectively).
• No significant differences in split times were observed for the 50-100m and 150-200m sections between indoor and outdoor conditions.
• Relative Average Velocity (RAV) was approximately 3% lower in the 100-150m indoor section, indicating reduced speed capacity.

Conclusions:

• The curved sections of indoor tracks (0-50m and 100-150m) are primarily responsible for the slower 200-m sprint times.
• Reduced speed development indoors may be linked to the biomechanical demands of navigating curved sections.
• Findings provide valuable reference data for coaches and can inform training programs to optimize indoor performance and athlete comparisons using RAV.
