CrossFit-Induced Rhabdomyolysis in a Young Healthy Indonesian Male

Abstract

CrossFit, a high-intensity interval training, keeps growing in trend and is one of the most favorable types of fitness, after wearable technology. However, an excessive workout is detrimental to the human body, particularly the muscle tissue. CrossFit is known to cause exercise-induced rhabdomyolysis, a concerning disease with potentially devastating consequences. Nevertheless, only a few case reports have described this disease, and this is the first case report of such disease in Indonesia to the best of our knowledge.A 27-year-old, previously healthy and active Indonesian male presented with dark urine and myalgia in lower extremities after 720 repetitions of squats three days before admission. His urinalysis showed +1 blood, 2-7 red blood cells/high power field (HPF), but negative protein. Laboratory results showed an increase in creatine phosphokinase (CPK) (54,250 U/L) and LDH (1,670 U/L) levels, consistent with exerciseinduced rhabdomyolysis, and serum calcium of 1.87 mmol/L, with normal serum creatinine and BUN level. He was hospitalized for two days and was treated with intravenous hydration therapy.CrossFit-induced rhabdomyolysis is a potentially devastating disease. Apart from prompt diagnosis and treatment, further research regarding the safe number of repetitions for CrossFit training, particularly for lower extremities are needed. Predictors of CrossFit-induced rhabdomyolysis must be sought throughout, and participants' awareness should be increased.

21st century medicine and emerging biotechnological syndromes: a cross- disciplinary systematic review of novel patient presentations in the age of technology

“…In the sections below we divide our analysis of the clinical cases by those caused by (i) consumer technology (e.g., gaming devices) and (ii) healthcare technology (e.g., glucose sensors). (i) Medical Specialties -Consumer Technology Biotechnological syndromes may arise from our interactions with technology outside of the healthcare setting, such as injuries from tasers (36-38), e-Cigarettes (39,40) and exercise machines (41). Computing technologies were common culprits of these harms, such as the 64F who developed third-degree burns requiring partial foot amputation due to an overheating laptop (42).…”

Common Orthopaedic Injuries in CrossFit Athletes

“…26 There have been several case reports published on rhabdomyolysis in CrossFit; however, the largest study following 523 CrossFit athletes found that 11 participants (2.1%) went on to develop rhabdomyolysis. [27][28][29] Rhabdomyolysis most commonly presents with generalized muscle pain and soreness, swelling, and dark colored urine 24 to 48 hours after an inciting event. 26 Any sudden strenuous exercise, including high-intensity CrossFit exercise, can result in exertional rhabdomyolysis and require hospitalization.…”
