| Summary: | The aim of the current study was to analyze the possible differences between the use of different kinds of thresholds to assesshigh-intensity acceleration efforts, both in number and distance covered in young elite soccer players. A total of 26 young soccer playerswere analyzed during 18 competitive matches (n=108). High-intensity acceleration efforts were assessed using an individual relativethreshold based on the capacity of acceleration from different initial speeds, considering high-intensity acceleration when it was >75%of the maximal acceleration (>75% amax). It was also used a threshold >21 km·h-1 when the acceleration intensity was >75% amax, andabsolute thresholds of >3 m·s-2 and >4 m·s-2, both in number and distance (meters). Post hoc analysis showed pairwise significantdifferences between the use of high-intensity thresholds (p < .05), in number and distance. The results showed that the use of absolutethresholds could overestimate (>3 m·s-2) and underestimate (>4 m·s-2 and >21 km·h-1) high-intensity acceleration efforts (both in numberand distance) in comparison with the use of an individual relative threshold (p < .05), whereas a threshold based on high-speed runningcould underestimate high-intensity acceleration efforts (p < .05). Therefore we conclude that the use of absolute acceleration thresholds(>3 m·s-2 and >4 m·s-2) may not be appropriate to analyze these efforts in young soccer players. In addition, speed running thresholdscould underestimate high-intensity actions developed in short distance, being more appropriate to combine with an individual relativethreshold to assess high-intensity action in soccer matches. |
