Background: In soccer, the capacity for acceleration and high-speed tasks extends beyond linear sprints to encompass a broad spectrum of multidirectional movements, including curvilinear sprints. We aimed to correlate mandatory speed-related capabilities with curve sprint (CS) performance in male professional soccer players.
Methods: Twenty-one players (age 25.
This study investigated the associations between pre-season and in-season performance with external workload in professional soccer players. Twenty-one players completed hamstring strength, countermovement jump (CMJ), 20-m sprint, and Yo-Yo intermittent recovery tests before (pre-season) and after 8 weeks (in-season). External workload (total distance, high-intensity running distance, number of sprints, and power plays) was quantified during this period, and used to divide the average above and below subgroups outcome by outcome for further analyses.

As a result, this study examined the effects of an 8-week strength training program comprising eccentric-emphasized prone leg curl adjusted according to the individual strength imbalance status.
Methods: Ten professional soccer players (26.
Article Synopsis
- Professional football clubs often assess players' hamstring-to-quadriceps (H:Q) strength ratios before the season to help prevent injuries, particularly hamstring strain injuries (HSI).
- A study of a Brazilian football team revealed that nearly 59% of players sustained HSIs during a certain season, prompting an examination of their pre-season H:Q ratios.
- Results showed that players who went on to sustain HSIs had significantly lower H:Q ratios and higher quadriceps strength compared to uninjured players, suggesting a link between these lower ratios and the risk of injury.
