Abstract
Cleary, MA, Sadowski, KA, Lee, SY-C, Miller, GL, and Nichols, AW. Exertional rhabdomyolysis in an adolescent athlete during preseason conditioning: a perfect storm. J Strength Cond Res 25(X): 000-000, 2011-The purpose of this brief review is to present a case of a healthy, male adolescent athlete (age = 16 years, body mass = 67.9 kg, height = 165.5 cm) who participated in a 3-day preseason wrestling camp which resulted in hospitalization for exertional rhabdomyolysis. As part of the preseason conditioning program directed by the coaches, the athlete completed 60 minutes of short, intense intervals of wall-sits, squats, sit-ups, push-ups, lunges, and plyometric jumps. The following day, the athlete continued his vigorous training consisting of running drills. That night he noticed voiding dark brown urine the color of cola. The day after the camp ended, the athlete reported to his Athletic Trainers with the chief complaint of severe bilateral leg pain in his quadriceps. Two days after the initial assessment, he was admitted to the hospital where he was diagnosed with exertional rhabdomyolysis based on creatine kinase (CK) levels that peaked at 146,000 IU·L, elevated far beyond normal (normal range = 58-280 IU·L). The athlete was hospitalized for 6 days where he received intravenous normal saline for rehydration, and his CK levels were assessed daily. Athletic Trainers, personal trainers, physical education teachers, and coaches should be aware that exertional rhabdomyolysis is the most common form of rhabdomyolysis and affects individuals who participate in novel and intense exercise to which they are unaccustomed. Stressful ambient conditions may lead to dehydration and exacerbation of the condition, particularly when the individual is not accustomed to the exercise intensity.

Abstract
OBJECTIVE: The objective of this study was to perform an investigation evaluating if cervical spinal manipulative therapy (SMT) can increase grip strength on judo athletes in a top 10 national-ranked team.
METHODS: A single-blinded, prospective, comparative, pilot, randomized, clinical trial was performed with 18 athletes of both sexes from a judo team currently competing on a national level. The athletes were randomly assigned to 2 groups: chiropractic SMT and sham. Three interventions were performed on each of the athletes at different time points. Force measurements were obtained by a hydraulic dynamometer immediately before and after each intervention at the same period before training up to 3 weeks with at least 36 hours between interventions.
RESULTS: Analysis of grip strength data revealed a statistically significant increase in strength within the treatment group after the first intervention (6.95% right, 12.61% left) as compared with the second (11.53% right, 17.02% left) and the third interventions (10.53% right, 16.81% left). No statistically significant differences were found in grip strength comparison within the sham group. Overall differences in strength were consistently significant between the study groups (P = .0025).
CONCLUSION: The present study suggests that the grip strength of national level judo athletes receiving chiropractic SMT improved compared to those receiving sham.
