Abstract: Sports and exercise are a part of physical activity (PA) that is considered to be an essential risk factor for prevention of chronic diseases. Many types of physical fitness (PF) programs are available. CrossFit is a modern program recently gaining worldwide recognition due to the claim that it focuses on overall PF. The aim of this study was to investigate the effect of CrossFit on selected PF components of adult males. The components tested included: Cardiorespiratory endurance, body composition, flexibility, muscle strength, muscle endurance, muscle power, speed, and agility. We also compared the effect of CrossFit with traditional fitness center training and with a control group. A total of 21 subjects participated, and were allocated into three groups, each of 7 subjects: CrossFit (CF), traditional fitness center (TFC), and control (CF). In the CF group, subjects participated in a minimum of 24 workout sessions within 8 weeks at a CF facility. As for the TFC group, subjects participated in a minimum of 24 workout sessions within 8 weeks at a fitness center. Subjects in the CTL group did not perform any exercise for a period of 8 weeks. Tests of PF were conducted before and after each of the programs. The results showed that the CF group significantly improved six of the eight selected components of PF: flexibility (p=0.002), muscle strength (p<0.001), muscle endurance: push-ups (p=0.002) and sit-ups (p=0.038), power (p<0.001), agility (p=0.009), and speed (p=0.001). In the TFC, there was significant improvement in three components: flexibility (p=0.039), strength (p=0.030), and muscle endurance: push-ups (p=0.014) and sit-ups (p=0.049). The CTL group showed no significant improvement. CrossFit provided favourable results in improving the overall PF of the subjects when compared to the other groups. On the other hand, the TFC group had some improvement in the health-related components of PF but not in the skill-related components, whereas in the CTL there was no improvement in PF. Therefore, we v conclude that CrossFit is effective in improving overall PF. Moreover, the study confirms that any level of physical activity is better than none.
