The character of play and match performance varies depending on playing style and opponent quality. To win a Grand Slam, a player must win seven matches in a row, and in the later rounds, players more often face opponents who are more equal and of higher quality. The aim of this study is to compare the rally pace between men and women in the early and late rounds of the US Open. Furthermore, we compare additional match characteristics (i.e., rally time, number of rally shots, time between points, and the work-to-rest ratio) between these tournament phases. In each category, selected factors from eight early-round matches and seven late-round matches...

The 100 m sprint and the marathon represent disciplines with different demands on speed and endurance. The aim of this study was to analyze and compare the historical development of Czech women’s performances in these disciplines, identify key trends, and assess the dynamics of performance improvement. For the analysis, data on the 50 best performances by Czech women for each year in the period 1976–2025 were collected. The best performances (elite), the average of 3 (sub-elite), and the average of 15 (broader performance base) of the best performances in both disciplines were compared. The analysis showed that the 100 m sprint has a long-term...
Steel Man: A Case Study on Equal Opportunities in Sport

Studia Kinanthropologica 2025, 26(3):111-119
This study examines the ethical problem of fair opportunity in sport, using the Czech endurancestrength competition Steel Man (in Czech Ocelový muž) as a case study. The event, founded in 1999 by Karel Vydra, combines five disciplines – pull-ups, sit-ups, bench press repetitions, a 5 km run, and a 40 km cycling time trial. It involved 40–70 participants per year, including men, women, and juniors. In 2017, the organisers introduced a new scoring system with recalculations based on age, sex, and body weight to achieve greater fairness. Archival records, scoring tables, and official results from 1999 to 2019 were examined through a conceptual-ethical...

This pilot study aimed to evaluate the effect of a seven-day creatine or placebo supplementation on the interpretation and execution of gymnastic elements among healthy recreational athletes (n = 10, age: 22–25 years). During both the pre-test and post-test sessions, participants were given one minute to study ten described and printed gymnastic floor elements. They were then asked to verbally recall the elements and immediately perform them. Between the two testing sessions, participants supplemented daily with either 20 mg of creatine (n = 5) or a placebo—maltodextrin (n = 5). No significant differences were observed between the control...
