To Measure Peak Velocity in Soccer, Let the Players Sprint

Kyprianou, E, Di Salvo, V, Lolli, L, Al Haddad, H, Villanueva, AM, Gregson, W, and Weston, M. To measure peak velocity in soccer, let the players sprint. J Strength Cond Res 36(1): 273-276, 2022-Expressing externals loads relative to a player's individual capacities has potential to enhance understanding of dose-response. Peak velocity is an important metric for the individualization process and is usually measured during a sprint test. Recently, however, peak velocity was reported to be faster during soccer matches when compared with a 40-m sprint test. With the aim of developing the practice of individualized training prescription and match evaluation, we examined whether the aforementioned finding replicates in a group of elite youth soccer players across a broader range of soccer activities. To do this, we compared the peak velocities of 12 full-time male youth soccer players (age 16.3 +/- 0.8 years) recorded during a 40-m sprint test with peak velocity recorded during their routine activities (matches, sprints, and skill-based conditioning drills: small-sided games [SSG], medium-sided games [MSG], large-sided games [LSG]). All activities were monitored with 10-Hz global positioning systems (Catapult Optimeye S5, version 7.32) with the highest speed attained during each activity retained as the instantaneous peak velocity. Interpretation of clear between-activity differences in peak velocity was based on nonoverlap of the 95% confidence intervals for the mean difference between activities with sprint testing. Peak velocity was clearly faster for the sprint test (8.76 +/- 0.39 m center dot s(-1)) when compared with matches (7.94 +/- 0.49 m center dot s(-1)), LSG (6.94 +/- 0.65 m center dot s(-1)), MSG (6.40 +/- 0.75 m center dot s(-1)), and SSG (5.25 +/- 0.92 m center dot s(-1)), but not sprints (8.50 +/- 0.36 m center dot s(-1)). Our data show the necessity for 40-m sprint testing to determine peak velocity.

Automated summary

This study aimed to compare the peak velocity performance of youth soccer players in different soccer activities, and found that the peak velocity during a 40-m sprint test was significantly faster than during matches, skill-based conditioning drills, and different-sized games. This indicates the necessity of conducting a 40-m sprint test to determine peak velocity.
