Article Synopsis
- The study aimed to investigate the differences in early versus late rapid force production in female soccer players during a specific hamstring assessment using force plates.
- 21 elite female soccer players participated, and they performed maximal isometric contractions to measure peak force and rapid force (RF) development at two time intervals: early (0-100 ms) and late (100-200 ms).
- Results showed significant differences, with early RF reaching about 52-54% of peak force compared to only about 15% for late RF, suggesting that tracking early RF could help practitioners optimize performance assessment and inform injury prevention strategies.
Calf injuries are common in professional football; thus, the establishment of reliable and time-efficient methods of measuring the peak force capabilities of the plantar flexors with equipment that is accessible to football practitioners is valuable. In this study, we determined the preliminary reliability and feasibility of a new test, termed the kneeling isometric plantar flexion test (KIPFT), for footballers. Twenty-one male youth footballers (age = 17.

- The study analyzed match-play data from professional male football over two seasons to understand how competition level (English Championship vs. League One) and playing position affect peak running speeds.
- Results indicated that League One matches showcased higher peak running speeds compared to Championship matches, and that playing positions greatly influenced these speeds, particularly highlighting the faster speeds of wide midfielders compared to forwards and defenders.
- The findings suggest that both league division and position-specific roles significantly impact the physical performance of players, with implications for training regimens in professional football.
Article Synopsis
- The study analyzed the effects of 90 minutes of competitive football on countermovement jump (CMJ) performance, creatine kinase (CK) levels, and urine osmolality (Uosm) in elite players throughout a season, focusing on their links to external match load.
- It involved 18 footballers, with data collected 24 hours before and 48 hours after matches, revealing a significant increase in post-match CK levels and a decline in various CMJ performance metrics.
- Results indicated that CMJ performance is closely related to high-intensity activities during matches, highlighting the importance of these measures for assessing player readiness and shaping recovery strategies.
Professional rugby league clubs implement training programmes for the development of anthropometric and physical characteristics within an academy programme. However, research that examines seasonal changes in these characteristics is limited. The purpose of the study was to evaluate the seasonal changes in anthropometric and physical characteristics of academy rugby league players by age category (i.

The purpose of the present study was to evaluate the anthropometric and physical characteristics of English academy rugby league players by annual-age category (under 16s-under 20s) and between backs and forwards. Data were collected on 133 academy players over a 6-year period (resulting in a total of 257 assessments). Player assessments comprised of anthropometric (height, body mass, sum of 4 skinfolds) and physical (vertical jump, 10- and 20-m sprint, estimated V[Combining Dot Above]O2max via the yo-yo intermittent recovery test level 1, absolute 1 repetition maximum [1RM], and relative squat, bench press, and prone row) measures.
