• Using Absolute vs. Relative Velocity Zones [Random Thoughts on GPS]

Using Absolute vs. Relative Velocity Zones Suppose you are coaching two distance runners, one with MAS (Maximum Aerobic Speed) of 18km/h and one with MAS of 21 km/h. The former is definitely more aerobically fit and would crush the latter in most middle to long distances (taking into account that threshold is proportional to MAS)....

• Individual Qualities vs Positional Demands

What I...

I am afraid that this article got away from sole RST/RSA/RSS discussion. The things I warned against, besides trying to answer whether RST/RSA is overrated, are the following

• Repeated Sprint Ability is Overrated? [Part 3]

The study by Carling et al. “is the first to investigate in detail the characteristics of repeated high-intensity movement activity patterns in professional soccer match-play and demands specific to positional role” (p. 332).I am posting the abstract here, while I am pretty sure the full paper can be downloaded
