The Prevalence of High Blood Pressure among Marathon Runners during Beirut-Marathon 2014

Marathon is a long-distance running race. It is one of the endurance events which have some health benefits. However, the incidences of sudden cardiac deaths that have occurred during marathons imply an element of risk as well. In this paper, the authors aimed to assess the prevalence of high blood pressure (BP) and cardiovascular risk factors among marathon runners during Beirut-Marathon 2014.

A total of 325 marathon runners were divided into 42 km (30 runners) and 10 km groups (295 runners). They were assessed for cardiovascular risk factors by measuring their BP and answering a questionnaire. The questionnaire composed of 22 questions related to demographic information, risk factors, medical history, family history, medical checkups, use of antihypertensive drugs and definition of hyponatremia. 

The results demonstrated that 1) the majority of 42 km runners were males 29 (96.7%) vs. 205 (69.5%) in the 10 km group, (P = 0.001); 2) The age of the runners in 42 km group was older than that in 10 km group (47 ± 13.8 years old vs. 38.5 ± 14.6 years old; P = 0.0025); 3) The prevalence of hypertension was 46.7% in the 42 km group as compared to 31.2% in the 10 km group (P = 0.08); 4) Systolic BP (SBP) was higher in 42 km group vs. 10 km group (143 ± 22.4 mm Hg vs. 129.9 ± 17.8 mm Hg; P = 0.0004); 5) The heart rate was lower among 42 km vs. 10 km group (71 ± 11.1 bpm vs. 84 ± 16 bpm; P < 0.0001); 6) Only 10% of the runners in both groups reported that they had hypertension (HTN).

In summary, there is a high prevalence of HTN among marathon runners but minorities were aware that they had hypertension. The 42 km runners tend to be older with higher systolic blood pressure as compared to the 10 km runners.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Remarks on the Complexity of Signed k-Domination on Graphs

Read  full  paper  at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=53574#.VMnXsCzQrzE Author(s)    Chuan-Min Lee 1 , Cheng-Chien Lo 1 , Rui-Xin Ye 2 , Xun Xu 2 , Xiao-Han Shi 2 , Jia-Ying Li 2 Affiliation(s) 1 Department of Computer and Communication Engineering, Ming Chuan University, The First American University in Asia, Taoyuan, Taiwan, Chinese Taipei . 2 Department of Electronic Information Engineering, Fuzhou University, Fuzhou, China . ABSTRACT This paper is motivated by the concept of the signed k-domination problem and dedicated to the complexity of the problem on graphs. For any fixed nonnegative integer k, we show that the signed k-domination problem is NP-complete for doubly chordal graphs. For strongly chordal graphs and distance-hereditary graphs, we show that the signed k-domination problem can be solved in polynomial time. We also show that the problem is linear-time solvable for trees, interval graphs, and chord...

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...
