ABSTRACT
BACKGROUND: The purpose of this study was to estimate changes in the aerobic- and anaerobic-dependent performance tasks in paratroopers during 18 mo of their military service. METHODS: There were 39 Polish Army recruits, enlisted to the paratroops, who volunteered for this study. The subjects were examined on enlisting and then after 3, 12, and 18 mo of the service. Anthropometry, aerobic capacity (V(O2max), V(O2OBLA), PWC170), anaerobic power and capacity (using Wingate test), performance in the repeated supramaximal exercises and motor performance indices (battery tests for locomotory endurance, agility, explosive power, strength and muscular endurance) were assessed. RESULTS: Military training produced a significant (p) < 0.05) increase in the body weight (by 4%), lean body mass (by 5.7%) and selected body girths. This was associated by the decrease in body fat from 15% to 13.1%). No significant changes in the aerobic fitness indices were noted. The studied soldiers showed significant increases in anaerobic power (by 5.9%) and anaerobic capacity (by 9.7%) accompanied by a substantial improvement in the performance in the repeated supramaximal exercises. There were also striking improvements in the variables which reflected muscular endurance and explosive power (by 32 78%), a substantial increase in the variables which reflected locomotory endurance (by 12.4%), agility (by 13.7%) and speed (by 11%), and a small rise in the static strength (by 4%). CONCLUSIONS: Overall, the present results show that the military training for paratroopers improves the motor performance and the anaerobic-dependent performance tasks and leads to favorable changes in the body composition but does not result in the improvement of aerobic fitness.

A case of a 21-year-old smoker has been described, clinically asymptomatic, in whom radiological examination revealed numerous diffused lesion in the lungs. On the basis of histological examination revealed numerous diffused lesions in the lungs. On the basis of histological examination of the lung biopsy specimen collected by means of videothoracoscopy, histiocytosis of pulmonary Langerhans cells has been diagnosed. The instituted treatment with prednisone and abstinence from nicotine lead to the remission of pulmonary lesions. Videothoracoscopy proved to be an effective method of collection of biopsy specimens from the lungs in diagnosis of diffused pulmonary lesions.

A case of a primary synchronous lung cancer is presented. Both tumors were removed via a simultaneous both sided posterior lateral thoracotomy. The radical surgical procedure produced respiratory insufficiency resulting in grave adaptation problems and the need to put the patient on a respirator. Rehabilitation allowed the patient to overcome the initial problems allowing light physical work without dyspnea.
