Van Os Stephan Performance Analysis

Overall Performance

Stephan Van Os completed the 2024 Amsterdam Hyrox race with an overall time of 01:36:23, placing him in the top 52% of his overall and age group categories. His performance was fairly balanced, though the total running time was slower than average by 01:09, indicating room for improvement in running efficiency. His initial running segments were strong, suggesting he started the race with a faster pace than average, which may have contributed to fatigue in later segments. Stephan's performance suggests a hybrid athlete profile with strengths in both running and strength-based exercises, as evidenced by superior times in running 1, sled push, and sled pull. However, he encountered challenges in sustained running performance and specific exercises such as wall balls and burpees broad jump.

Segments to Improve

• Total Running Time: Stephan's overall running was slower than average. To enhance running endurance and efficiency:
  • Training Strategy: Incorporate interval training sessions focusing on medium to long distances to build stamina and speed. Use a mix of steady-state aerobic runs and high-intensity interval training (HIIT) for variety.
  • Exercises: Long runs (8-10 km), tempo runs (4-6 km at a challenging pace), and track intervals (e.g., 400m repeats at race pace).
• Wall Balls: This segment was 00:58 slower than average, indicating a need for improved strength and technique.
  • Training Strategy: Focus on lower body and core strength, as well as practicing wall ball technique to increase speed and efficiency.
  • Exercises: Squats, overhead presses, core stability exercises, and wall ball practice drills (e.g., repeated sets of 15-20 wall balls with correct form).
• Burpees Broad Jump: This segment was 00:54 slower than average. Improvement can be made in explosive power and endurance.
  • Training Strategy: Enhance explosive leg power and cardiovascular endurance through plyometric exercises and circuit training.
  • Exercises: Box jumps, burpee variations, and plyometric lunges. Incorporate burpee broad jumps into HIIT circuits to simulate race conditions.
• Roxzone: Stephan spent more time in the transition zone than average, indicating a need for faster transitions.
  • Training Strategy: Practice transitions to reduce downtime between exercises.
  • Exercises: Simulate race conditions in training by setting up stations for each exercise and practicing quick transitions between them.

Race Strategies

• Pacing Strategy: Adopt a more consistent pacing strategy throughout the race to avoid early fatigue. Consider starting at a slightly slower pace to conserve energy for later segments.
• Efficient Transitions: Prioritize reducing transition times by practicing the sequence of each station and minimizing unnecessary movement.
• Focus on Form: Maintain proper form in exercises such as wall balls and burpees to enhance efficiency and reduce energy expenditure.
• Adapt to Fatigue: Plan for compromised running performance post-strength exercises by incorporating compromised running drills into training, such as running immediately after squats or wall balls.
