文章大意:这是一篇说明文。主要介绍了跳绳的好处。

1 . Jumping rope is popular but we tend to ignore (忽视) its benefits.     1     A study found that college men who spent 10 minutes jumping rope daily for six weeks improved their cardiovascular (心血管的) fitness just as much as college men who spent thirty minutes jogging for the same time. Here are some benefits of jumping rope.

    2    

Since most of your major muscles are working when you jump rope, the exercise creates a lot of heat in the body. Your body needs to burn more fuel to produce this energy, so it burns lots of calories. It burns more calories than any other exercises, such as jogging, cycling and swimming.

Improves coordination (协调)

Jumping rope requires good coordination, especially as you advance to more skilled moves.     3     It improves coordination by requiring several body parts to communicate in order to complete one movement. The feet must jump in time with the wrists turning in order to create a continuous jumping motion.

Reduces injury risk

With your improved coordination from jumping rope, you’ll be less likely to get hurt either during exercise or in daily activities.     4     As a result, you are more agile (灵活的) and your body awareness is improved greatly. This guarantees fewer injuries.

Improves heart health

Since jumping rope gets your heart pumping, it’s great for your cardiovascular system and heart health. Jumping rope can increase your VO2 Max (最大摄氧量), the measure of the maximum amount of oxygen a person can breathe during exercise. The higher someone’s VO2 max, the more cardiovascular endurance (耐受力) they have.

Jumping rope gives us a full-body workout with just one piece of equipment and one move.     5     Jump to some music, or take your rope to a nearby park to enjoy the fun.
