1 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

My dad and I had been looking forward to the Stale cross-country race of my senior year of high school, which would be the climax (顶点) of my existence.
I was the fastest runner on my team, and I was supposed to make it into the top fifteen. We had been working towards this race for three years. It was everything to me, and it was everything to my dad. He was a runner and was wild with joy by my success in running. He made it to every race, even flying home early from business trips to see me run. I always listened for his voice, which rang above the crowd-telling me to relax my arms, calling out my time. He pushed me. He cheered for me. He believed in me. We spent countless hours on the sandy canals of Arizona. Breathing in the dust of the desert, the blossoms of the orange trees, and the terrible smell of the dairy farm, we made our way across the city. We pounded miles and miles into our running shoes, marking with every step the path to greatness. It was a journey that was just ours. A dream passed on from one generation to the next.
Then the big day came. It was hotter than normal - too hot. My throat felt like a field of cotton, cracked with the summer heat, as I waited for the gun to fire. I gazed out at the crowd; dozens of familiar faces from church and school flickered across my view. They had come for me. They were counting on me. I saw my dad set his watch, worry and excitement etched across his face. With the sound of a gunshot, the race began.
For the first two and half miles, I felt great. I had never before been so ready for something. The weeks leading up to the race were filled with hard practices and a strict diet. The scorching sun beat upon my back, blinding me with its brilliance. Nothing was going to stop me, though.

People refer to never forgetting how to ride a bike or throw a baseball as examples of “muscle memory”, the result of a motor learning.
Previous research has shown that the changes actually persist in the muscles themselves. In one study of mice, the results suggest that after nuclei in muscle cells multiply in response to an overload of training, those extra nuclei aren’t lost during subsequent periods of inactivity. They are retained (保留), essentially waiting to be reactivated. If you fell off the fitness wagon (马车) during the pandemic, don’t be frustrated. Once you have got additional nuclei, you are banking the capacity.
Ultimately, muscle memory is a payoff for all the past work you put into learning a sport.
A.The best way to tap into it is to “get back on the horse”. |
B.Physiologists, on the other hand, define it in a different way. |
C.This convinces the researchers that muscle memory may not be long lasting. |
D.That is to say, we can do the sports automatically without conscious thought. |
E.It is generally safe to increase these elements by 5 percent every week or two. |
F.It is evident that the more you exercise, the more muscle memory savings you will have. |
G.All this news about muscle memory is encouraging for those who fell off the fitness scheme. |
5 . The Upside to Being Outside
Research shows that being in nature makes people feel good, whether they’re roughing it in the wilderness for days or just hanging out at a local park for a while. One study was conducted in the city of Birmingham, Alabama. Researchers found that most participants’ mood and well-being improved significantly when they spent time in urban parks, even though the average visit was only around half an hour.
How does nature boost people’s happiness? Scientists say that spending time in natural settings reduces stress and anxiety, which benefits mental and physical health. Research shows our brains are more relaxed in natural settings.
To most people, it’s not news that nature can be calming. But multiple studies have found that spending time in nature also has some more surprising benefits, like improving creativity and problem-solving.
What accounts for the connection with cognition and creativity? It could be that a good dose of nature acts as a cure to information overload. Everyday life involves a lot of multitasking. Some scientists theorize that spending time in nature enables our brains to rest and recover from mental tiredness.
Naturally, scientific studies don’t cover everything that’s great about the great outdoors.
A.One study revealed that people were better at figuring out puzzles after a four-day camping trip. |
B.According to many scientific studies, there’s a good chance it’ll make you happier, healthier, and more creative. |
C.What’s more, the lift people get from nature is long lasting. |
D.Lots of people enjoy fun activities outside, like swimming, riding bikes, or climbing trees. |
E.When the only light you’ve seen all day is the glow of a screen, it might be a good idea to switch it off. |
F.This means that whether you’re studying or playing video games, heading outside to give your brain a break might help you get to the next level. |
G.So, kicking back in a park is a bit like treating your mind to a restful mini vacation. |

9 . It’s no surprise that there’s a link between exercise and mental health. But scientists have now made it official: research has found a direct connection between movement and mood. Why does exercise hold so many benefits for our mental health?

10 . Some people prefer to have a bite to eat before hitting the gym, known as a fed workout. Others would like to wait until after exercising to refuel their bodies, called a fasted workout.
If you want energy and strength for an ideal workout, you need fuel. A fed workout will provide your body with power. Eating before exercise may help you sustain longer sessions and lift heavier weights.
Many fitness enthusiasts are not on board with this idea. They report feeling sick and inactive while trying to exercise after eating. With a fasted workout, you may not get the usual indigestion. Experts for fasted workouts further claim that eating afterwards makes your body use its fat reserves for energy, meaning you will burn more fat.
Deciding when to eat for an ideal workout is a personal choice. Both fasted workouts and fed activities have their benefits and shortcomings.
A.However, a fasted workout might not work for you. |
B.How your body will respond is based on your workout intensity. |
C.These benefits can result in burning more fat and shaping a slimmer body. |
D.To eat or not to eat, that is the question on many fitness enthusiasts’ minds. |
E.Think thoroughly and discuss with your fitness instructor before taking a choice. |
F.Knowing what to eat for an ideal workout is just as important as knowing when to eat. |
G.A person doing a 30-minute session a day may not have a problem with fasted workouts. |
