CrossFit, a privately owned company founded in 2000 and headquartered in the U.S., offers wellness and fitness services. Employing approximately 1650 people, the organization focuses on promoting and organizing CrossFit fitness programs, events, and competitions.
CrossFit's stated goal is to increase work capacity across various domains, developing the ability to perform well in any physical task. CrossFit training incorporates diverse functional movements, including calisthenics, weightlifting, gymnastics, bodyweight exercises, indoor rowing, aerobic exercise, running, and swimming. This training model is used both for general fitness and competitive sport, with participants competing in timed or measured routines across these disciplines. The barbell jerk, a key component of Olympic weightlifting and functional fitness, is also a relevant exercise within CrossFit. A study explored the potential of ultrasound-guided percutaneous neuromodulation (US-guided PNM) to enhance muscle strength gains in the upper limb for healthy individuals participating in CrossFit, though the efficacy remains unexplored.
