Article Synopsis
  • The study analyzed the training and match loads of 30 professional male soccer players, focusing on how these loads varied by playing position and examined the relationship between their metabolic metrics and running speeds.
  • Findings revealed that central midfielders covered the most distance during matches, while forwards had the highest metabolic power outputs, and central defenders had the least high-speed running.
  • It was concluded that physical responses in training don’t match match demands by position; thus, both metabolic and traditional metrics should be utilized together for effective load monitoring in soccer.

Two production systems and several ages at slaughter were used: 12, 14 and 16 months for outdoor rearing (with the final finishing phase in the system, in which fed was based on natural resources, mainly acorns and grass) and 8, 10 and 12 months for animals reared indoors (intensive system: with feed based on commercial fodder) to evaluate their effect on the muscle fibre population and size of the , (LT) muscle, as well as fresh loin quality traits. Animals that were older at slaughter revealed increased fibre sizes of the LT muscles in the pigs reared in the system. The LT muscles of the animals reared in intensive systems had a lower percentage of type I fibres and higher size of type IIB than those reared in the system.

Analysis of the key performance variables in soccer is one of the most continuous and attractive research topics. Using global positioning devices (GPS), the primary aim of this study was to highlight the physiological response of a professional soccer team across competitive microcycles in-season according to the most influential contextual performance variables. Determining the training load (TL), a work ratio was established between all recorded data within the training sessions and the competitive profile (CP).

Article Synopsis
  • The study investigated the impact of a coach's dismissal on the locomotion and metabolic responses of professional soccer players in Spain's top three divisions, focusing on four weeks before and after the change.
  • Data showed that players under the dismissed coach ran longer distances at various high-speed thresholds during training, particularly in the First and Second divisions, suggesting they were pushed harder in practice.
  • However, in matches, performance metrics like the equivalent distance index and acceleration were similar between the two coaches, indicating that changing coaches mid-season did not enhance players' physical performance in training or competition.
