Topic: Sports cardiology
Purpose: hemodynamic responses to maximal exercise testing cover the general population. Bloodpressure (BP) responses in athletes are reported at rest and during ambulatory BP monitoring. BP responses associated with different classes of sports are lacking.
Purpose: To determine BP responses to exercise related to different classes of sports in young athletes (=35yr).
Methods: Young athletes who had pre-participation cardiovascular screening, maximal exercise-ECG, and were engaged in regular physical training and competition > previous 6 month were included in this retrospective study during 2000–2008. Bicycle exercise protocol until exertion, 75 watt (men) or 50 watt (women) during 4min, increment 25 watt / 2 min. BP and ECG at rest, each increment, and recovery phase was measured manually.
Results: 475 athletes were included, 308 men and 167 women, age 9–35yr (mean 24yr). Number of training hours 1–30/wk. Mean resting BP was 122 mmHg systolic and 73.5 mmHg diastolic. Mean resting heart rate was 61.7 bpm on ECG. Mean BP responses to maximal exertion in different classes of sports (mmHg) are in table.
Conclusion: this is the first study that demonstrates different BP responses associated with different classes of sports. the highest systolic and diastolic BP responses were recorded in moderate static-low dynamic sports. the lowest diastolic BP responses were recorded in moderate static-high dynamic sports. Values above the criteria for hypertension on exertion were in moderate static-low dynamic and high static-low dynamic classes of sports. Further studies are warranted to define “normal” blood pressure response to exercise in different classes of sports
BP = blood pressure in mmHg.

Topic: Sports cardiology
Purpose: Preparticipation screening is recommended by the European Society of Cardiology (ESC) and were published two years ago. the intention was to reduce sudden cardiac deaths in athletes and to evaluate athletes for severe heart conditions for their own protection. the objective of this study was to evaluate the benefitial effects from an additional blood pressure measurements as it is not specifically mentioned (German society of sports medicine does not recommend blood pressure measurement for preparticipation screening) and to focus on blood pressure as an important risc factor in sports activities. As younger athletes come more into focus, the incidence of high blood pressure in athletes is unknown.
Methods: According to the ESC and EAPCR guidelines, preparticipation screening (history, auscultation, ECG and blood pressure measurements) was done in a network setting with 37 physicians with a sports medicine diploma who do regular preparticipation screening. If elevated blood pressure values (> 140/90 mmHg) were present, a second measurement after another 20 minutes of rest was recommended. All athlete files were collected at our center and evaluated. Starting April 2007 until December 2008, 1024 consecutive athlete-files were evaluated.
Results: We received 1024 screened athlete files. Athletes had to be active at least 4 hours per week Age range was 8 to 68 years of age with a mean age of 37.3 years. 727 athletes were male, 297 were female. Mean systolic blood pressure was 135.48 mmHg (range 81 210), mean diastolic blood pressure was 79,98 mmHg (range 45 118). the results were analysed in decades of age. 145 athletes were 10 to 20yrs old, 75 athletes were 20 to 30yrs old. 16.7 % of the female athletes in the age group 10 20 and 7.9 % in the age group 20 to 30 years had elevated blood pressure (systolic, diastolic or both). In male athletes 26.6% under the age of 20 (10–20) and 59.3 % in the age group 20 to 30 had elevated blood pressure. 60 of the 220 athletes under the age of 30yrs had elevated blood pressure.
Conclusion: Our results show elevated blood pressure values in every fourt young athlete under the age of 30 with a peak incidence (six out of ten) in male athletes age 20 to 30 yrs. Our small collectice of 1000 evaluated athletes suggest a higher rate of elevated blood pressure higher screening numbers. Preparticipation screening with blood pressure screening seems to be helpful and very important and hypertension screening and control should be evaluated in further studies.
