The purpose of this study was to examine the effect of a soccer small-sided game (SSG) on performance, inflammatory, muscle damage and hormonal indicators. Twenty-two male soccer players participated and were assigned to either experimental (EXP = 12) or control (CON = 10) groups. Subjective fatigue (RPE) and lactate (La¯) were measured during the SSG; vertical squat jump (SJ), 20-m sprint, creatine kinase (CK), interleukin-6 (IL-6), cortisol (C), and testosterone (T) were measured before (PRE), after (POST), 24 h, 48 h, and 72 h after the SSG in the EXP group.

The purpose of the present study was to examine straight line (SL) and changes of direction (COD) sprinting and dribbling abilities after a standing and a flying starting position. Twelve amateur U12 male soccer players participated in the study.

Participants were allocated in four (4) groups based on their age: the Under 11 (U11) group consisted of 101 players, the Under 14 (U14) group consisted of 100 players, the Under 17 (U17) group consisted of 118 players and the Adults (AD) group consisted of 43 players. The typical error, the limits of agreement and the ICC of PAT and PVR test were examined.

- The study analyzed how futsal games affect metabolic, hormonal, and muscle damage markers in male players.
- It involved 21 top-level futsal players divided into two groups based on playing time: the Long Playing Time (LPT) group and the Short Playing Time (SPT) group.
- Findings revealed that players in the LPT group experienced greater increases in muscle damage indicators like lactate dehydrogenase and creatine kinase, along with a decrease in the testosterone/cortisol ratio, indicating the intensity of the game significantly impacts physiological responses.
Background: The purpose of the present study was to examine the variation of aerobic performance parameters of elite Greek soccer players.
Methods: In the study participated twenty-four (24) male professional soccer players (age: 24.3±4.
