CrossFit is one of the fastest growing sports. Its growing popularity also applies to its competition form. This pilot study aims to analyse strength, endurance performance and their relationship to the resulting ranking in the CrossFit Open. Furthermore, the forms of training of elite Czech crossfitters are described in more detail. The research sample consisted of the 20 best Czechs (average height, age, and bodyweight of 180cm, 28.5 years and 90.7 kg respectively) according to the CrossFit Open ranking. The questionnaire was used to collect information regarding the training regime and their current performance parameters. Descriptive statistics include the correlation between individual performances and overall ranking. Crossfitters had very good strength parameters in exercises with external load and also with their bodyweight (average values: clean and jerk 141.5 kg, snatch 113.9 kg, back squat 184.1 kg, strict press 87.2 kg, deadlift 217.9 kg, strict handstand push-ups 21.5 reps., pull-ups 20.6 reps.). The Olympic weightlifting performance (snatch and clean and jerk) was the strongest predictor for placing (-.606 resp. -.625, α = .01). The weekly training time was 800-900 minutes and contained mostly combined training units with a total of 9.2. Given the interesting results achieved in this pilot study, more detailed and validated studies are needed.
