What does it mean to be strong in sports? 10

Good afternoon, dear. Physical strength refers to the development and strengthening of the body's muscle groups and skeletal system through strength training and exercises in training. Physical strength is the basis for an athlete to generate and control power when performing high-intensity exercises.

It not only improves the explosiveness and high-speed athleticism of the athlete, but also improves the physical endurance and stability of the athlete. The purpose of training the body is to make the muscles stronger, more flexible and more vibrasive, so that they can better cope with various strength demanding sports, such as weightlifting, batting, running, jumping, pushing and pulling, etc. Through strength training, athletes can improve joint stability, reduce the risk of injury, and improve the quality of the performance of athletic skills.

In addition, proper strength training can also promote bone growth and density increase, preventing osteoporosis.

Strength exercises are key to maintaining a healthy weight over the long term. You should incorporate it into your cardio workout.

Strength exercises increase your muscles, which are the main calories you burn. And it strengthens the body and makes it work more efficiently, so that your cardio can reach a higher level. And aerobic exercise can lower your body fat.

Another often-overlooked benefit of strength training is its ability to resist two of the most complex consequences of aging: muscle loss and loss of bone density.

I recommend strength exercises 3 times a week. When you improve, you can increase the weight and number of sets used.

One set is the number of repetitions you do for the same exercise before taking a short break. A set should have 8-10 reps. One repetition is the completion of one action. In general, multiple repetitions of low weight increase muscle endurance, and few repetitions of high weight increase muscle strength.

How many should you use? You should choose 60-80% of your maximum ability, most commonly 70%. Your greatest ability is the maximum weight you can lift.

I recommend starting with a light weight that you know you can lift, and then increasing it to a weight that you will get tired from doing 8-10 times.

Remember to warm up before strength exercises and stretch afterward.

In order to illustrate this problem, it is necessary to talk about the energy metabolism of muscle work.

Muscle contraction requires energy**, and the direct source of energy is adenosine triphosphate (ATP). The amount of ATP in the muscles is very limited, and it is depleted in only 5 seconds after a violent contraction, so it is necessary to have a temporary form of energy storage to replenish ATP in time to ensure that the muscles continue to contract. This ATP-replenishing stock substance is called phosphocreatine (CP), which is catalyzed by enzymes to rapidly transfer high-energy phosphate bonds to diphosphate glandular bitter molecules to form ATP.

However, CP can only be used for a short period of time. Ensuring the energy of muscle contraction** depends on the oxidation of sugars and fatty acids.

Both sugars and fatty acids can be used by aerobic oxidation to provide energy for muscle contraction. Aerobic metabolism requires oxygen to keep the reaction going, called the oxidation system, to support energy for moderate-intensity endurance exercise**. Large-intensity activities with continuous strong muscle movement, due to insufficient oxygen**, require anaerobic oxidation for energy, that is, anaerobic glycolysis of the lactic acid system.

The lactic acid produced by anaerobic glycolysis enters the blood through the muscle cell membrane and reaches the liver for gluconeogenesis, which then replenishes blood sugar.

Therefore, low- to moderate-intensity exercise that provides energy through aerobic metabolism is called aerobic metabolic exercise (aerobic exercise); High, super-intensity exercise that provides energy from anaerobic metabolism is called anaerobic metabolic exercise (anaerobic exercise).

Strength exercises, also known as weight-bearing exercises and resistance exercises, are often thought to be exercises for shaping the body, but in fact, it has a very positive effect and impact on overall health to increase strength, increase flexibility and balance, improve mood and better cope with stress, protect heart health, focus more, and look younger.

Strength exercises include sit-ups, weightlifting, pull-ups, push-ups, and many more.

What is strength exercise?

On the one-year anniversary of the countdown to the London Olympics, the sports channel of **TV began planning to shoot a five-part documentary "The Power of Sport". The film is divided into five episodes and began on July 23, 2012 and aired for five consecutive days. The whole film takes the four years between the 2008 Beijing Olympics and the 2012 London Olympics as the time coordinates, reflecting the role of sports in the survival and development of Chinese people from the three levels of ordinary people, athletes and countries, and reflecting the changes that have taken place in Chinese society's understanding and awareness of sports.

Strength exercises include two-up lifts, weightlifts, pull-ups, squats, push-ups, and more.

Strength exercises, also known as weight-bearing exercises, socks, resistance exercises, people usually think that this is a good book for Brother Wu to shape the body, in fact, it increases strength, increases flexibility and balance, improves mood, better copes with stress, protects heart health, is more concentrated, and looks younger" and so on have a very positive effect and impact.
