What is the effect of roller skating, and what is the function of the pulley?

1. Enhance body coordination and balance.

Roller skating is good for balance, flexibility, emergency response and thinking. The balance and coordination function of the body is mainly restricted by the flexibility, excitement and inhibition of the conversion ability of the nervous system, and the human nervous system is one of the earliest and fastest developing systems, so children and teenagers can play roller skating in the sensitive period of nervous system development and exercise the function of the central nervous system as soon as possible, so that the body movements are coordinated, flexible, soft and powerful, which will benefit you for life. Roller skating also has a fat-burning effect and will prevent the symptoms of childhood obesity.

2. Exercise joint support and flexibility.

When playing roller skating, the knee joint and ankle joint need to support the body appropriately to complete the support, sliding, turning and other actions, which has a good exercise effect on the support ability of the joint, especially the flexibility. A survey of falls in older adults showed that ankle support and flexibility are key factors in preventing falls. As a result, children, teenagers and adults alike can benefit from roller skating.

3. Whole-body aerobic exercise can improve the whole body.

Roller skating correctly can actually improve your whole body, because roller skating itself is a full-body aerobic exercise, and an athlete who has mastered the basic skills of roller skating will have a heart rate of 120 beats during roller skating. At the same time, in the process of roller skating, the waist, hips, thighs, and ankle muscles are all exerted, and those with good technique will use reasonable swing arms to strengthen the balance of the body and improve the gliding effect, so that the upper limbs and even the chest muscles can be exercised, therefore, roller skating is in line with the basic elements of aerobic exercise.

In general, roller skating has a maximum oxygen consumption (the benchmark for measuring exercise intensity) that of running, which is effective in maintaining the optimal intensity of aerobic exercise. According to the study, the number of heart beats measured when rollersking at a speed of 23 km/h is 74% of the maximum heart rate, which is a typical aerobic exercise that can achieve cardiovascular and fat-burning effects. Increasing the speed to 28 km/h will increase the number of heart beats to 85% of the maximum heart rate, which will improve the stamina of the muscles.

With consistent pulley movements, you should be able to adjust your body to the best condition.

Of course, if you look at developing cardiorespiratory endurance, roller skating is indeed inferior to running or brisk walking, and some studies have confirmed that roller skating for the same amount of time is not as caloric as running, and its impact on cardiorespiratory function is not as good as running. However, roller skating is less damaging to the joints than running, especially because of its fun and general flexibility, which is more interesting and easy to stick to than running.

Because the wheels rotate when roller skating is stepped, the elasticity of the wheels made of polyurethane has little impact on the joints, so the elderly also 9002 this sport. Wearing a helmet and protective gear makes the risk of falling injuries relatively small.

Hope it helps.

The effect of roller skating is much older, it can enhance body coordination and balance, exercise joint support and flexibility, full-body aerobic exercise can improve the whole body, can exercise the stability of children, etc., this is a full-body sport, which can be used as an exercise project when you are working in your spare time, and now sports health is becoming more and more concerned by the country, including the Olympic Games have been on roller skating this event competition, if you are professional enough, you can go to participate in professional competitions, the benefits are much older.

Benefits: 1. Brain: exercise balance ability, which can be called brain balance exercise.

2. **: The average calorie consumption is 285 calories for 30 minutes of slow and continuous brushing; Intermittent roller skating (1 minute low sprint + 1 minute upright easy skating) burns 450 calories in 30 minutes.

3. Joints: The impact force of roller skating on joints is about 50% lower than that of running.

4. Heart: Promote the improvement and metabolism of cardiovascular and cerebrovascular system and respiratory system. Skate slowly for 30 minutes, with a heart rate of 148 beats per minute.

Disadvantage: When playing roller skating, it is most likely to fall and get injured. Especially children, some of them don't know how to protect themselves, and it is also possible to break their arms by holding the ground with both hands when falling.

The function of the pulley is to pull the load, change the direction of force, and transmit power.

A pulley is a small wheel with a groove around the perimeter that rotates around an axis. It consists of a grooved disc that can be rotated around the central axis and a flexible cable (rope, tape, steel cable) that crosses the disc.

chains, etc.), which can rotate around a central axis, is called a pulley.

Movable pulley: The balance of forces in a movable pulley.

Eco-friendlinessRoller skating itself does not produce any pollution, advocates the concept of healthy environmental protection, and is a fashionable health sport.

FitnessRoller skating is a whole-body sport, which can promote the improvement of cardiovascular and cerebrovascular system and respiratory system function and the strengthening of metabolic effect, such as promoting the improvement and metabolism of cardiovascular and cerebrovascular system and respiratory system function, and can enhance the strength of arms, legs, waist, abdomen and other muscles and the flexibility of various joints of the body, especially for the mastery of people's balance ability is of great help and coordination.

Entertaining: Roller skates are highly entertaining, fun in terms of speed and technique, and can be practiced individually or in groups. Therefore, whether it is a casual sport or a small competition between friends and classmates, roller skating can free people from the usual tense and heavy study and work, and carry out some activities appropriately, so as to achieve the purpose of physical and mental relaxation.

Instrumentality: In addition to the above. In addition to its characteristics, roller skating also has a feature that many sports do not have, that is, it can be used as a means of transportation.

In general, on smooth roads, roller skating can be used as a means of transportation. Of course, the grip will vary depending on the road conditions, but basically there is no problem. In today's increasingly congested traffic, roller skating has become a popular and fashionable means of transportation.

Of course, we still have to remind everyone to pay attention to traffic safety when skating and shuttling through the streets where cars come and go.

1. Before practicing roller skating, you should prepare for activities, especially the joints and ligaments of the wrist and lower limbs.

2. If possible, wear some protective equipment, such as wrist pads, elbow pads, knee pads and helmets for roller skating. Nowadays, many sports stores have this kind of special protective gear for roller skating.

3. Check the screws and other fastening parts of the roller skates before practicing to avoid injuries due to problems with the roller skates during the skate.

4. Beginners should practice in the beginner field or within the specified range, or practice in a place with fewer people as much as possible, and do not slide arbitrarily. When learning to roller skate for the first time, it's a good idea to have a skilled partner or tutor to tutor you.

5. It is forbidden to do dangerous or obstructive actions of others, especially in crowded public roller skating rinks, such as several people holding hands to slide, going in the wrong direction on the speed skating track or sliding in the direction of everyone in the opposite direction, jumping around, scurrying in the field, chasing and fighting, stopping suddenly, etc., which are both hindering others and prone to dangerous things.

6. Wrestling is inevitable when learning to roller skate, but learn to protect yourself while wrestling. The method is: when you want to fall forward or sideways, you should take the initiative to bend your knees and squat, and use your hands to support the ground to cushion and reduce the force of the fall; When you want to fall backwards, you should also take the initiative to bend your knees and squat, lower your center of gravity, try to let your buttocks sit down first, and pay attention to protecting the tailbone, and at the same time lower your head to avoid your head falling backwards and hitting the ground; When falling, try to avoid holding the ground with one hand with a straight arm, which can easily injure the wrist.

7. People with serious diseases (such as heart disease, high blood pressure, etc.) should not participate in intense roller skating activities, and can at most slow skating exercise. In addition, people who have drunk alcohol and are overly tired should not participate in roller skating activities.
