1 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.

For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.

Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”

Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

2 . Clocking 16 hours, 46 minutes, nine seconds, the athlete Chris Niki didn’t finish with the shortest time when he recently completed his first Iron Man Race-but he did quite well.

After swimming 2. 4 miles, the 21-year-old Floridian cycled 112 miles. Even after suffering a fall from his bike during the second leg of the race, he called on his inner strength to get back up, keep going and get the job done.

3 . Fitness Magazine recently ran an article titled “Five Reasons to Thank Your Workout Partner.” One reason was: “You’ll actually show up if you know someone is waiting for you at the gym, ” while another read: “    1    ”   With a workout partner, you will increase your training effort as there is a subtle (微妙) competition.

It also listed her favorite sports and activities, and provided her phone number.     4

6 . Why Is Exercise Cool?

•Exercise Strengthens Muscles

Did you ever do a push-up or swing across the monkey bars at the playground?    1    By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.

•    2    

Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion”, which means you can move your arms and legs freely without feeling tightness or pain.

•Exercise Keeps the Balance

    3    Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic things.    4    If you’re not very active, your body won’t need as many calories. Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.

•Exercise Makes You Feel good

It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.

But you may not know that exercising can actually put you in a better mood.    5    It’s just another reason why exercise is cool!

A．Exercise Makes You Flexible

B．Exercise Makes Your Heart Happy

C．Those are exercises that can build strength.

D．So you want to do some aerobic (有氧的) exercise right now?

E．But if you’re active, your body needs an extra measure of calories or energy.

F．Food gives your body fuel in the form of calories, which are a kind of energy.

G．When you exercise, your brain releases a chemical which may make you feel happier.

8 . If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.

Scientists in Denmark have been studying over 1,000 joggers and non-joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries.

Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy. Anything more is just unnecessary, and it may be harmful.”

The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than “iron man” events, triathlons and long-distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study， “You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn't actually do too much.”
