tend your ticker with a heart monitor
heart-rate monitors help put workouts in perspective.
they are “the ultimate personal trainer,” said david wright, a certified fitness specialist and army master fitness trainer. “the main reason for using a heart-rate monitor is for safety.”
a basic heart-rate monitor consists of a transmitter strapped to the chest or over the breastbone. it send signals to a receiver, usually worn on the wrist. the receiver displays the heart rate – the rate at which your heart is sending blood to your muscles and lungs.
a monitor also can reduce the risk of injury.
“what happens most of the time,” wright said, “is that the novice will go out and practice at a rate that is way too high. when you overexert yourself, you are at risk for injury, and you could be putting your heart at risk.”
the monitor “can also be used as a way to motivate,” wright said. “you are able to assess and monitor your own training. it is something a beginner can use and an advanced runner can use.”
most important, once you buy your monitor, you must find the proper heart rate for your workouts. to do this, wright recommends this formula:
· determine the maximum heart rate by substracting your age from 220. for example, a 50-year-old would have a maximum heart rate of 170 beats per minute. you do not want your heart rate to exceed the maximum during exercise.
· determine you resting heart rate. sit quietly in the morning before consuming stimulants such as caffeine. count the number of times your heart beats in one minute. a 50-year-old might have a resting heart rate 0f 75 beats per minute.
· substract the resting rate from the maximum. (170-75=95 beats per minute). the 95 beats per minute is your hear-rate reserve.
· multiply the heart-rate reserve by the intensity level at which you want to exercise. for example, a beginner might want to exercise at a 60 percent intensity level (95 beats x 60 percent = 57 beats per minute).
· add the resting heart rate. (75) to the intensity level (57). in this example, 132 is the target heart rate.
· “the 50-year-old man would not want to go above 132 beats per minute when he exercises,” wright said. “most importantly, whatever you do, find your zone. if you exercise any higher than the recommended heart rate, you put yourself at risk for injury.”
醫學英語閱讀：心臟病高發三大原因ing hostility and depression unchecked
放任敵意和沮喪的情緒
Are you feeling stressed, hostile, or depressed? It can take a toll on your heart. While everyone feels this way some of the time, how you handle these emotions can affect your heart health. “Those likely to internalize stress are in greater danger; research has shown a benefit to laughter and social support,” Dr. Reynolds says。
你是否感到壓力大、有敵意或是沮喪?這些都對你的心臟有害。雖然所有人都會偶爾經歷這些，但你處理這些情緒的方式能夠極大地影響到你的心臟健康。“常把情緒壓在心裏的人很危險，研究表明大笑或是社交活動有利於健康。”Reynolds醫生說。
flossing
牙齒不清潔
While the exact reason is unknown, there is a strong link between gum disease and heart disease, Dr. Ostfeld says. If you don’t floss, sticky, bacteria-laden plaque build up over time, which can lead to gum disease. One theory is that these bacteria trigger inflammation in the body。
Ostfeld醫生說，雖然確切的關聯尚不清楚，但牙齒疾病與心臟病的確有着強烈的關聯。如果你不清潔牙齒，時間長了，那些黏糊糊充滿細菌的牙垢就會積累起來，造成牙齦疾病。有一種理論認爲這些細菌會引發機體炎症。
ding fruits and vegetables
不吃水果和蔬菜
“The most heart-healthy diet is a plant-based diet,” Dr. Ostfeld says. That means loading up on fruits and vegetables, nuts, whole grains, low-fat dairy, and protein, and keeping junk food to a minimum. In fact, new federal dietary guidelines recommend that half of each meal should be composed of fruits and vegetables。
對心臟最有好處的食物大多是植物，”Ostfeld醫生說。這意味着要多吃水果和蔬菜，堅果，全麥食品，低脂牛奶和蛋白質，別吃垃圾食品。事實上，最新的聯邦飲食建議每頓飯應該至少有一半是水果和蔬菜。
