Prevalence of smoking among Israeli male athletes.

A survey of smoking habits was carried out on 2447 males age 14-40 years. The subjects were athletes trained in a wide variety of sports. Overall 15.5% of the athlete population were smokers. When broken down into training groups, the highest smoking prevalence was reported by subjects not engaged in specific training, while the lowest prevalence was reported by endurance trained athletes. When divided into specific sports, the highest percent of group smoking was found in soccer players. Smoking prevalence increased with increasing age. No significant differences in smoking prevalence existed between groups of varying ethnic origin. This study provides data on groups of athletes to target in smoking intervention programs.

Effect of handlebar gripping on blood pressure during cycle ergometry.

The effects on SBP, DBP and HR of gripping the cycle ergometer handlebar during dynamic cycle ergometry were evaluated in 39 healthy males. Heart rate, SBP and DBP were measured at 150 Watt power load while gripping and not gripping the handlebar of a cycle ergometer. The sequence of gripping first or second was randomized. No differences in SBP, DBP or HR were shown under the two treatments. For submaximal cycle ergometry the influence of static handgrip on the handlebar does not seem to have a significant influence on SBP, DBP or HR response to dynamic exercise.

Effect of exercise on salivary composition and cortisol in serum and saliva in man.

The effect of exercise on electrolytes and cortisol levels in serum and saliva was examined in 27 young, healthy male volunteers who performed graded submaximal cycle exercise for nine min at up to 85% of their age-predicted maximal heart rate. Seventeen men performed the Wingate anaerobic test for 30 s. A significant increase in pulse rate and systolic blood pressure and a decrease in diastolic blood pressure were found, and serum concentrations of Na+, K+, and lactate were significantly elevated immediately after exercise. A nonsignificant increase in saliva and serum cortisol levels was found. Significantly lowered salivary flow rate and elevated salivary K+, protein, and lactate concentrations were found within ten min after exercise. Salivary Mg2+ was significantly elevated after anaerobic exercise only.

Complete heart block and physical performance.

Complete heart block (CCHB) is a very rare finding. The problems in such patients are: additional heart malformations, the appearance of Stokes-Adams or syncopal attacks, and the occurrence of different grades of ectopy. Most patients with CCHB without structural heart disease develop normally and can lead a normal life. If there are no Stokes-Adams attacks or high grades of ectopy at rest and exercise, they have a normal physical capacity and can perform strenuous work and sports. Increased stroke volume, cardiac enlargement, and extraction of very large amounts of oxygen from the blood were found to be compensatory mechanisms of adaptation. Some authors have discussed the possible role of training in this adaptation.

Common ECG changes in athletes.

The various ECG changes found in a group of 3,000 healthy athletes are discussed on the basis of eight representative ECG recordings. The common findings were sinus bradycardia, atrioventricular conduction disturbances, left and right ventricular hypertrophy according to the accepted voltage criteria, right axis deviation, intraventricular conduction disturbances (mainly in the right side of the heart), and various disturbances of the repolarization phase. The literature on this subject is reviewed, and the possible mechanisms involved in production of the various ECG changes are discussed. It is pointed out that in the absence of other evidence suggestive of cardiovascular disease, these changes should be considered as a normal variant and not lead to restriction of physical activity.

Wenckebach A-V block: a frequent feature following heavy physical training.

Among 126 top Israeli athletes, in whom an ECG was obtained during a random survey, 11 had first-degree heart block (P-R greater than or equal 0.21 sec.) and in three of them Wenckebach's phenomenon was found. The latter could be demonstrated only after 15 minutes' rest in a recumbent position and was abolished by sitting, standing, and the administration of atropine. This subjects with Wenckebach's phenomenon were followed for 6 years. The heart block was found to be present only during seasons of intensive training and could not be demonstrated a few weeks after the training was reduced in intensity or stopped. No heart disease or diminution of performance developed during 6 years of follow-up. Transient second-degree heart block in top athletes is probably much more frequent than hitherto suspected, but it can be demonstrated only if the athlete is examined during rest and in the recumbent position. It is assumed to be a physiological phenomenon related to heavy physical training.
