When the competitive season ends, many athletes find themselves in need of a break—mentally and physically. However, the offseason is not just for rest—it’s a crucial period to improve strength, speed, and aerobic capacity. Structured training can provide a significant edge when the next season begins.
This blog will focus on improving aerobic capacity and how to effectively test and train this key area during your offseason. Aerobic Capacity: Build Endurance and Recovery

Aerobic Testing
Aerobic conditioning is key for recovery and maintaining high performance during prolonged exertion. To assess your aerobic capacity, use tests like:
- Bronco Test: A shuttle test that measures maximal aerobic speed (MAS) by completing 1.2km of 20m, 40m, 60m shuttles.
- Yo-Yo Intermittent Recovery Test: A sport-specific test, ideal for team sports. It measures your ability to recover between high-intensity intervals, such as sprints.
Aerobic Training Integration
Improving aerobic capacity requires consistent, targeted conditioning to build endurance and recovery efficiency.
- Steady-State Cardio: greater than 20 minutes continuous training working between 70-85% MAS, 2-3 times per week. This increases your aerobic base and stamina.
- High-Intensity Interval Training (HIIT): Incorporate HIIT to improve both aerobic and anaerobic systems. Alternate between bursts of maximum intensity (20-40 seconds) and recovery periods (1:1 for power or 3:1 for stamina). HIIT is highly effective for improving performance in sports requiring repeated high-intensity efforts.
- Cross-Training: Activities like swimming, cycling, or rowing can improve cardiovascular fitness while reducing the repetitive strain from sport-specific movements.
