Problems practicing high intensity programs and CrossFit

Although there is evidence supporting the benefits of intense exercise programs, as in the case of CrossFit and HIIT according to Gibala et al. (2012), Shiraevy Barclay (2012) & Kessler et al. (2012), great care must be taken in its application. The correct evaluation and progression from the beginning of the subject are crucial variables to benefit from any training program, however, when training is performed with very high intensities and large training volumes, the risk of injury and overtraining appear. As the American College of Sport (ACSM) describes, it warns of the incredible impact that this type of activity generated on musculoskeletal injuries, among which fibrillar tears, ligament strains, stress fractures and abdominal pain at various levels of severity (Bergeron). et al., 2011). Continuing with Bergeron et al. (2011) cited different negative aspects of intense and strenuous programs: • Huge fatigue. • Great oxidative stress. • Less resistance for subsequent physical efforts. • Increased perception of progressive effort. • Variants with competitive components force, in large part, the practitioners of committing abuse and excess, obviating the principles of the progression of the load for training. • Execution of techniques with a lesser degree of security, probably derived from the high intensity required by the effort of practice. Taking more account of these negative aspects of intense and strenuous programs, Winwood et al. (2014) recently published a study on the number of injuries suffered by Strongman's athletes. The article shows the vast majority of athlete injuries, being acute and moderate intensity injuries, announces Orlando Jose Veloso Angola. These are due to the large amount of effort and associated fatigue. The study was carried out through a survey that recorded the injuries of 213 athletes (31.7 years of average age) during one year of practice. An average of 6 injuries per 1000 hours of training were observed (Fig. 1), which originated mainly in the tendon (23%) and muscle injuries (38%).
Taking into account the data reflected above, it seems logical to suggest caution and caution with strength training in strenuous training programs, taking into account the proper execution technique as well as the greatest possible individualization to try to reduce the risk of injury. Orlando Jose Veloso focuses more on CrossFit, sometimes in the boxes you can find people who do not know how to technically perform the exercises to be performed in the Wod, especially those related to Olympic lifts, loads, etc. In addition, performing them at high intensity can generate a person who seeks to improve their health with a completely opposite effect if the individualities of each one of the people who join this sports specialty are not taken into account. Without forgetting that CrossFit is a sports modality that has its own competitions. Therefore, the training of these people in these specialties will often be focused on improving the tests that are held in future competitions to come. So to practice it, it is necessary to individualize the exercises and the intensity with which they are performed, in addition to an excellent execution technique to avoid any type of subsequent anomaly. However, there are very few articles published in scientific journals that talk about this sport. It is true that it is spoken in informative magazines and forums, but these publications do not present studies on health, but rather describe the activity as it is carried out. Hak et al. (2013) state in their study that in CrossFit training, of the total of those surveyed, 70% suffered injuries during their training and only 7% required surgical intervention. One of the biggest controversies in injuries in CrossFit, such as rhabdomyolysis, did not occur in any of the cases. Therefore they made an estimate of the injury rate that resulted in 3.1 for every 1,000 hours of CrossFit training and finally concluded that the rate of injuries in CrossFit are similar to those observed in lifting Olympic weights, but they are less than in contact sports such as rugby. Therefore, performing CrossFit under control and planning guidelines does not carry a greater risk of injury than in any other sport modality as long as it is individualized in each user, summarized Orlando Veloso.
