Extensive Intervals Workouts for Middle Distance Runners

Extensive Intervals refer to a category of crucial workouts that are used for building aerobic power in middle distance runners.  They are introduced in the general preparation period and emphasized during the specific preparation and pre-competitive periods.  Aerobic power development requires many weeks of training because adaptations includes both bio-chemical and structural changes to the…

Assessing the Athletic Lifestyle of the Cross Country Athlete

More and more scientific studies on distance runners have shown that proper recovery facilitates faster physiological adaptation and enhances endurance-related performance. By ignoring recovery today, it all leads to tomorrow’s poor practice session and, eventually, poor recovery habits that are tough to break. It also reinforces attitudes that can lead to under-recovery injuries. However, by…

Anaerobic Speed Reserve for Distance Runners

The physiological concept of anaerobic speed reserve (ASR) is a relatively new concept to middle distance running.  ASR is defined as the difference between an athlete’s absolute maximum velocity and their maximum aerobic speed (vVO2 max).    The anaerobic/aerobic energy system contribution percentages for a sprint event of 400 meters or shorter is much different…
