In order to examine the effectiveness and safety of hydraulic resistance strength training in young males, 26 pre-pubertal males (mean age = 8.2 +/- 1.3 yr) completed a 14-wk strength training study. Subjects were evaluated before and after the 14-wk experimental period for pubertal state (Tanner's sexual maturity rating, serum testosterone, and serum(More)
This uncommon syndrome is caused by compression of the posterior humeral circumflex artery and axillary nerve or one of its major branches in the quadrilateral space. Forward flexion and/or abduction and external rotation of the humerus aggravate the symptoms. Discrete point tenderness is always found posteriorly in the quadrilateral space. Patients with(More)
The known sensitivity of joint scintigraphy in following the course of fracture healing caused the authors to believe that this radiologic technique might be valuable in the management of osteochondritis dissecans (OCD). Accordingly, 99mTc-diphosphonate joint scintigraphy was used on 18 patients with OCD of the knee. The average age was 13 1/2 years. The(More)
A 4 year prospective study (1982 to 1985) of high school varsity football injuries from the four Peoria high school football teams was undertaken. Two hundred fifty-one injuries were recorded among a player population of 598, resulting in an injury rate of 42.1% per 100 players. All of the players followed a prescribed preseason summer conditioning program(More)
A prospective clinical study used joint scintigraphy to investigate conservative treatment of juvenile osteochondritis dissecans (JOCD) of the femoral condyle. The predictive value of scintigraphic evaluation and various parameters (age at onset, sex, location and size of lesion) were analyzed. Over a 10 year period, the senior author followed 92 knees in(More)

Five football teams from major colleges in the nation were surveyed during practices and games in the 1976 season. Data were collected on three packages of information designed as a computer program for tabulation, analysis, and storage of data. Investigators, with a thorough knowledge of football and trained in the use of the program, obtained the data(More)
Eighty young athletes with weight training-related injuries were seen from August 1976 to August 1980. In 37 of the 80 athletes, it was difficult to pinpoint the cause of injury since the history revealed, in addition to weight training, either a program of running excessive mileage or participation in repetitive lap running in the gymnasium. The injuries(More)
