One of the questions I am most often asked when reviewing semi-professional clubs' first set of match data is, “how does this compare to the pros?” I’ve always found this an interesting question so decided to do some research to help answer it. I looked into 2 major areas of performance: distance and high intensity distance, fully expecting that professionals would not only cover more distance but also more distance at a high intensity.
When I first started my research into this topic, I was expecting a decent library of comparison studies of professional and semi-professional loads, however, there were surprisingly few, especially in football. So, when I could not find direct comparisons I looked into studies that looked at either professional or semi-professional matchplay loads and compared them myself.
Is it a realistic comparison?
Professional football clubs tend to train 4 to 5 days a week, compared to the majority of semi-pro clubs’ 2 days. Therefore, the logic is that because professionals train more, they are fitter and can therefore travel further and faster. Other variables such as quality of playing surface, exposure to the elements and whether or not your star player had to work a night shift before the game are also key contributors to whether this comparison is realistic.
When comparing in-season match distances, semi-professional players had a 7% lower total match distance (680 metres) compared to professionals. The 7% discrepancy is not considered statistically significant, which essentially means we cannot say for certain that pros consistently cover more ground than semi-pros.
Interestingly, that number would have been lower if not for the position which had the largest difference. The professional full-backs covered 14% (1341 metres) more distance than their semi-professional counterparts.
In Rugby League I was able to find studies that directly compared semi-professional and professional players, indicating the same results as above. Interestingly, they found that both professional and semi-professional players covered significantly more distance than players in the under 20 competition. While most studies tended to find little to no difference between the two professional levels in terms of total distance, it was found that professional players worked at a higher intensity in the first half than semi-professional players, which could explain greater fatigue in the second half. The semi-pro players, who were travelling at less intensity than the pros, showed less drop-off from the first to the 2nd half. While this looks more positive, it could be that despite the reduced difference between halves, the ground covered will have been less effective than that of their pro counterparts.
Though limited, this research is encouraging for those at the semi-professional level. It shows that players are capable of covering similar matchday distances to the professional level on less expansive training regimes. However, as we know, distance should never be used as the sole indicator of workload. It also highlights that if semi-professional players want to make a concerted difference to their performance, increasing their high intensity workload capabilities is a great option. Being able to out pace your opponents late in the game could make the difference between a positive or a negative result.
