Introduction to CrossFit: An initial analysis of the sport
Abstract
The main purpose of this study is to conduct a systematic review of the recent research output produced on CrossFit and to examine the benefits and risks of the CrossFit training. This work also aims to highlight the sparse number of scientific research produced on CrossFit and to emphasize the need for more studies in the field of CrossFit regarding the benefits and risks that occur during the high-intensity power training of this sport; a sport that presents an increasing recognition at the national and international scale, both by athletes and researchers. Systematic search of PubMed and Scopus was conducted. A total of 18 articles were included in this study. Based on the results of this study, the benefits of CrossFit include physiological, psychological and social effects of CrossFit on athletes. Accordingly, the risks of CrossFit mostly include musculoskeletal injuries at different body parts, such as shoulder, lower back, knee, ankle and elbow injuries. The findings of this study indicate that CrossFit training improves the six out of ten general physical skills of athletes, such as cardiovascular/respiratory endurance, stamina, strength, flexibility, power and balance, while the other four physical skills, such as speed, coordination, agility and accuracy are yet to be verified. In conclusion, both elite and novice CrossFit athletes must be in close cooperation with experienced sport experts in order to avoid the riks of injuries and at the same time exploit the benefits of the CrossFit training.References
