Overview Statement
Progressive overload and training thresholds each connect to a cyclist’s aerobic performance through physiological adaptations that improve the delivery and use of oxygen.
Component Relationship 1
Progressive overload can be effectively used to improve a cyclist’s aerobic performance by gradually increasing the frequency, duration and/or intensity of training.
Once the cyclist has adapted to their training program, this can be achieved by increasing the duration of sessions from one hour to 75 minutes.
This increased training stress on the cardiovascular and respiratory systems results in physiological adaptations, including increased haemoglobin and stroke volume levels.
These adaptations mean the cyclist can delay fatigue and maintain performance for longer, resulting in a faster time.
Component Relationship 2
Training thresholds connect to aerobic performance by ensuring that training occurs at an intensity above the aerobic threshold and below the anaerobic threshold, within the aerobic training zone.
To improve the performance of a cyclist, this would involve the athlete cycling continuously at 70–80% MHR within their training program.
Training at this intensity results in physiological adaptations including increased oxygen uptake and stroke volume.
These adaptations enable the cyclist to train and compete at a higher intensity for a longer duration because their heart is more efficient in delivering oxygen to the working muscles.
Implications and Synthesis
The relationships demonstrate that progressive overload and training thresholds work together to produce physiological adaptations that improve aerobic performance.
Overall, applying both principles enables the cyclist to delay fatigue, maintain a higher intensity for longer and achieve a faster performance time.
