Advantages and disadvantages of the four strokes (technical flow angle)

In this article, we will objectively evaluate the advantages and disadvantages of the four major strokes and the four most basic strokes. As a swimmer, relevant knowledge will help you to understand swimming more deeply and make swimming and body and mind combine perfectly.

breaststroke


Breaststroke is generally one of the first strokes that beginners come into contact with. Modern breaststroke has developed into whip breaststroke leg, and the breaststroke swimmer has also been broken down into several action stages, namely, returning the arm, sliding, paddling, chest and hand, all of which are done underwater or near the surface.

The advantage of breaststroke is that the head can easily get out of the water, the front vision is not affected, and there is no big breathing problem. Another advantage is that the hands and legs of breaststroke move synchronously in the same symmetry, which is also beneficial for beginners to master the initial movements, so breaststroke is easier to learn from all strokes.

The main disadvantage of breaststroke is that it is slower than other strokes and less efficient.

backstroke


Backstroke is the easiest stroke to learn after breaststroke. Backstroke, as its name implies, is swimming on the back, and backstroke leg is also a kind of whipping leg, and it should be whipped up and down alternately.

The hands of the backstroker swing like a windmill in turn. After the straight arm comes out from the hip, the straight arm moves to the top of the head to enter the water, and then grabs, pulls and pushes the water to the hip for one cycle.

The advantage of backstroke is that once the backstroke is well balanced, breathing is not a problem at all, and it is more efficient than breaststroke, and it can also do long-distance backstroke, and it can be used as an auxiliary treatment stroke for patients with low back diseases.

Backstroke also has disadvantages. The speed of backstroke is not as fast as freestyle and butterfly. For beginners, it is not easy to master the balance of backstroke. Therefore, the nose will often get water and choke, and for beginners, swimming will be very uncomfortable because they can’t look forward.

freestyle


Freestyle requires swimmers to lie prone, and the leg movements are the same as backstroke legs, which are also whipping legs, and they should be whipped up and down in a cross way. The hand movements require that the arm should be pulled back from near the thigh and head into the water, and then the water should be scratched and pushed to the thigh and then returned to the arm.

The advantage of freestyle is clearly that it is fast. Freestyle is the fastest and most effective stroke, and it is also the fastest stroke in competitive competitions, and it is also the favorite stroke of long-distance swimmers in recent years. Freestyle can achieve the minimum physical consumption for long-distance swimming.

The disadvantage of freestyle is that the face must be underwater for a long time and vertically downward, which requires turning your head when breathing. The coordination of breathing and body swimming in freestyle makes it one of the more difficult swimming postures to master.

butterfly stroke


Butterfly stroke is the most beautiful and difficult stroke among the four strokes. Butterfly stroke requires the body to do wave-like movements like dolphins, that is, whip the whole body. The underwater movement of the arm is actually similar to the front of freestyle, except that the hands are synchronized, and the water is thrown in front of the water after being pulled under the hips.

The advantage of butterfly stroke is that it is fast. Apart from freestyle, butterfly stroke is a relatively fast stroke, which is faster than breaststroke and backstroke. Another advantage is that it looks good and fun because of its unique dolphin-like body fluctuation.

However, one disadvantage of butterfly stroke is that it consumes too much and is not suitable for long-distance swimming. Another disadvantage is that it is not easy to learn, because butterfly stroke requires difficult body wave movements and the timing of arm ejection is not easy to grasp.

The technical advantages and disadvantages of the four strokes are briefly analyzed, which helps beginners to understand swimming and enhance their curiosity, and also helps swimmers to learn more about swimming. Help all people who love swimming to explain the problems encountered in swimming.

Table tennis Portugal tournament ends! Japan was wiped out, Guoping won three championships, and the men’s team was defeated.

In the Portuguese table tennis match in 2023, the audience witnessed a fierce confrontation and technical contest. This competition is not only a test of athletes’ skills, but also a test of their psychological resilience. In this competition, the confrontation between the Japanese team and the China Table Tennis Team is particularly eye-catching, and both teams have demonstrated a high level of competitive state and adaptability.

First of all, it should be pointed out that the China table tennis men’s team suffered a rare rout in this competition. This result undoubtedly shocked many table tennis fans and experts. China’s men’s team, which is usually known for its stability and strength, seems to be unable to cope with the Japanese team. On the other hand, the Japanese team showed a rare unity and fighting spirit, and they showed excellent performance and were full of strategy in the game.

By analyzing the competition process, it can be found that psychological factors played an important role in this competition, except for the similar strength of the two teams in the technical level. China players are a little nervous and insecure at the critical moment, while Japanese players seem to be more adaptable to the stressful environment and can better control the rhythm and mood of the game. This difference in psychological preparation may explain why the Japanese team can completely suppress the China team.

Next, it is worth noting that table tennis, as a sport with extremely fast speed, requires extremely high concentration and reaction speed, and puts forward extremely high requirements for athletes at the spiritual level. Keeping concentration and adjusting strategy are the key to winning, and this is where the Japanese players performed well this time.

Nevertheless, we can’t just focus on the results when evaluating the game. Failure is also the only way for growth and progress. Although the China table tennis men’s team failed to get what they wanted, their fighting spirit and efforts are still worthy of recognition and respect. Similarly, the victory of Japanese players also proves their determination to constantly improve and break through themselves.

Looking back on the whole Portuguese table tennis competition, while analyzing the technical details and strategic layout of the competition, the inner world of the athletes is equally important. Sports competition is not only a physical contest, but also involves many aspects such as will, emotion and psychological quality.

To sum up, in the report shared by the gentle ship SvE publishing platform to the readers, we see a panoramic and in-depth analysis of the 2023 Portuguese table tennis competition. This paper objectively analyzes various complicated factors in the fierce competition between two representative groups-Japanese team and China table tennis team, and especially emphasizes the important position of psychological level in high-level competitive sports.


Finally, it reaches the emotional resonance point in expressing respect and encouragement to the contestants regardless of success or failure. Everyone in the sports field deserves admiration: the losers are tenacious and brave for it; Successful people are inspired by their outstanding achievements. Through such in-depth reports and reflections, we have more realized that the sports spirit transcends the simple binary opposition between victory and defeat, and passed on this spirit of persisting in pursuing Excellence and never giving up.
