Types of pitching
In general, a ship has all six degrees of freedom. Accordingly, there are 6 types of pitching: three rotational - roll, pitch and yaw, and three reciprocating - vertical, longitudinal, transverse. All types of pitching are characterized by a period T
expressed in seconds, and amplitude, whose measure depends on the type of motion.
According to the degree of influence on the ship, they are located: Rolling Rotational vibrations around the longitudinal axis of the ship. The amplitude Θ
is expressed in angular measure.
Pitch Rotational oscillations around the transverse axis of the vessel. The amplitude Ψ
is expressed in angular measure.
Heave A back-and-forth motion along the vertical axis of a ship. It arises from the variable support force and the associated variable current displacement. The amplitude ζ
is expressed in a linear measure. Rolling Reciprocating motion along the transverse axis of the ship. Occurs during side waves. Longitudinal rolling A back-and-forth motion along the longitudinal axis of a ship during head or tail waves. Yaw Rotational vibrations around the vertical axis of a ship. Most often, its influence is difficult to separate from issues of controllability.

The effect of pitching on a ship
Compared to roll and pitch, the influence of the other four types is insignificant. However, it is taken into account when determining the operating conditions of equipment and/or combat use of airborne weapons. But in their pure form they are rarely found. While sailing, a ship encounters a combination of all of the above, but depending on the predominance, transverse and longitudinal are distinguished.
Rolling causes the ship's speed to slow down. The operating conditions of mechanisms and devices are deteriorating. Additional stresses arise in the hull and superstructures, and with a large amplitude of pitching and heaving, the hull hits the wave ( slamming
). Pitching causes seasickness.
With large amplitudes of motion, it can lead to loss of stability of the vessel and its flooding.
The vibrations of ship hull structures caused by pitching can be measured using a pallograph device.
Harm to health and saggy muscles
1) Any professional sport where overwork and doping are integral attributes is harmful to health. Be it bodybuilding, be it athletics, be it martial arts, or even chess! Falling from the horizontal bar while performing acrobatic elements is also harmful to health.
If you play sports at an amateur level, without trying to achieve world records, then this will only benefit your health. Most average jocks and turnstile men are amateurs, so their exercises only improve immunity and well-being.
Let us note that for maximum good health, it is better to combine several sports so that there are no imbalances in different aspects of physical development. The aforementioned CrossFit is ideal for this.
2) Muscles cannot sag. They do not turn into fat. Anyone who studied biology at school will refute these ridiculous tales. Without training, muscles simply decrease in size, regardless of how they are built up: with horizontal bars or in the gym. The muscle does not even know what exercise you are training it with.
If you train all your life, you will look as good when you are old as you did when you were young. Adjusted for age, of course. Here's an example of Sylvester Stallone , who has been training since he was 15 years old:
Sylvester Stallone at 67 years old.
But, if you don’t exercise at all, then at 67 years old (if you live long enough) your skin will really sag and you’ll look like a bag of... fill in with what.
Not saggy
Reduction methods
To reduce roll
the navigator tries to increase the period of natural vibrations of the hull by reducing the initial stability, so that the natural vibrations of the hull are 2-3 times greater than the characteristic visible period of storm waves falling on the ship; or increase the speed of the vessel to more often expose the vessel's hull to storm waves, and remove the vessel from the zone of resonant vibrations of an overly stable hull.[1]
Reduced pitching
possible with mutual compensation of hydrodynamic forces occurring during ship wave formation under conditions of exposure to high-height trochoidal waves on the hull. This is achieved by reducing the height and volume of the surface part in the bow end of the hull, blocking the stem with an undercut in its underwater part, as well as including a specially twisted surface of the ship's plating in the area of the bow chine, which sucks the crest of the diverging ship wave under the bottom of the hull.[2]
Folding trimmers are used (on high-speed catamarans from Incat) - by balancing them, adjusting their lifting force (controlled automatically by a computer), it is possible to reduce the level of pitching.
Today, the technology of ships with a small waterline area
(eng.
Small Waterplane Area Twin Hull
,
SWATH
) [3], there are about 50 similar vessels in the world. This is a rather expensive and complex production, but very effective. The stability of such a vessel is ensured by submerged pontoons, the presence of which is the main difference between this type of ship and catamarans or hydrofoils (catamarans are completely on the surface of the water, and hydrofoils develop high speed only in calm seas). Therefore, nothing can cope with waves of 5 points except ships with a small waterline area. Such ships are used in tourism, research and military applications.
Endurance and physical strength
Again, an attempt to compare completely different sports. What is considered an indicator of physical strength? Number of pull-ups? Acrobatic elements on the horizontal bar? Number of kg on the bar? Arm wrestling?
When horizontal bar lifters say that athletes are weak because they cannot do 10/20/30 pull-ups on the horizontal bar, they somehow forget that they themselves would not be able to lift such weights as bodybuilders, weightlifters and powerlifters.
The same goes for endurance. There is general endurance, and there is special. If the first one shows how long a person can make simple physical efforts (for example, running, walking, jumping), then the special one shows how resilient a person is in a certain sport.
CrossFit is a sport for those who are interested in an athletic body combined with excellent functional training.
In the gym, specific endurance will be the ability to recover quickly between sets of strength training. For horizontal bar lifters, the indicator of endurance will be the speed of recovery between sets of exercises on the horizontal bar.
In terms of the number of pull-ups, an advanced turnstile man will always outpace a muscleman, but if you force him to do pull-ups with additional weight (20-50 kg), most likely he will not be up to par.
A turnstile man will quickly run out of steam in the gym, a jock will quickly exhaust himself on the horizontal bar. Both will “die” in a minute on the wrestling mat, and the wrestler will be outdone by the marathon runner on the treadmill in no time. Although even a marathon runner will have trouble at the pentathlon competition.
The ultimate development of universal endurance is CrossFit, a discipline that trains all aspects of functional training, focusing on both aerobic and strength training.
And in arm wrestling, correct technique is much more important than brute physical strength. A professional 65 kg arm wrestler will “do” both a 70 kg turnstile and a 100 kg muscleman.

Potency and sport
The song “Valentin (DSI) - You are an Athlete”, which is very popular among turnstiles
Boxers, wrestlers and football players. Athletes, swimmers and biathletes. In general, everyone involved in sports is capable of giving girls orgasms.
People who play any sport (well, except chess) have better than those who do nothing. Moderate physical activity increases testosterone levels, the main sex hormone in men.
And erections are better in those who move a lot or do a lot of leg exercises - this helps improve blood circulation in the lower body. And active blood flow to the pelvic organs is like natural Viagra 
Stories about small penises and complexes are usually told by those (regardless of whether they are turnstile men or not) who have their own problems with this. How else can you explain your increased attention to the genitals of strangers?
Excerpt characterizing Jock
– I don’t think anything bad about anyone: I love everyone and feel sorry for everyone. But what should I do? Sonya did not give in to the gentle tone with which Natasha addressed her. The softer and more searching the expression on Natasha’s face was, the more serious and stern Sonya’s face was. “Natasha,” she said, “you asked me not to talk to you, I didn’t, now you started it yourself.” Natasha, I don't believe him. Why this secret? - Again, again! – Natasha interrupted. – Natasha, I’m afraid for you. - What to be afraid of? “I’m afraid that you will destroy yourself,” Sonya said decisively, herself frightened by what she said. Natasha's face again expressed anger. “And I will destroy, I will destroy, I will destroy myself as quickly as possible.” None of your business. It will feel bad not for you, but for me. Leave me, leave me. I hate you. - Natasha! – Sonya cried out in fear. - I hate it, I hate it! And you are my enemy forever! Natasha ran out of the room. Natasha no longer spoke to Sonya and avoided her. With the same expression of excited surprise and criminality, she walked around the rooms, taking up first this or that activity and immediately abandoning them. No matter how hard it was for Sonya, she kept an eye on her friend. On the eve of the day on which the count was supposed to return, Sonya noticed that Natasha had been sitting all morning at the living room window, as if expecting something, and that she made some kind of sign to a passing military man, whom Sonya mistook for Anatole. Sonya began to observe her friend even more carefully and noticed that Natasha was in a strange and unnatural state all the time during lunch and evening (she answered questions asked to her at random, started and did not finish sentences, laughed at everything). After tea, Sonya saw a timid girl's maid waiting for her at Natasha's door. She let her through and, listening at the door, learned that a letter had been delivered again. And suddenly it became clear to Sonya that Natasha had some terrible plan for this evening. Sonya knocked on her door. Natasha didn't let her in. “She'll run away with him! thought Sonya. She is capable of anything. Today there was something especially pitiful and determined in her face. She cried, saying goodbye to her uncle, Sonya recalled. Yes, it’s true, she’s running with him, but what should I do?” thought Sonya, now recalling those signs that clearly proved why Natasha had some terrible intention. “There is no count. What should I do, write to Kuragin, demanding an explanation from him? But who tells him to answer? Write to Pierre, as Prince Andrei asked, in case of an accident?... But maybe, in fact, she has already refused Bolkonsky (she sent a letter to Princess Marya yesterday). There’s no uncle!” It seemed terrible to Sonya to tell Marya Dmitrievna, who believed so much in Natasha. “But one way or another,” Sonya thought, standing in the dark corridor: now or never the time has come to prove that I remember the benefits of their family and love Nicolas. No, even if I don’t sleep for three nights, I won’t leave this corridor and forcefully let her in, and I won’t let shame fall on their family,” she thought. Anatole recently moved in with Dolokhov. The plan to kidnap Rostova had been thought out and prepared by Dolokhov for several days, and on the day when Sonya, having overheard Natasha at the door, decided to protect her, this plan had to be carried out. Natasha promised to go out to Kuragin’s back porch at ten o’clock in the evening. Kuragin had to put her in a prepared troika and take her 60 versts from Moscow to the village of Kamenka, where a disrobed priest was prepared who was supposed to marry them. In Kamenka, a setup was ready that was supposed to take them to the Warsaw road and there they were supposed to ride abroad on postal ones. Anatole had a passport, and a travel document, and ten thousand money taken from his sister, and ten thousand borrowed through Dolokhov. Two witnesses - Khvostikov, a former clerk, whom Dolokhov used for games, and Makarin, a retired hussar, a good-natured and weak man who had boundless love for Kuragin - were sitting in the first room having tea. In Dolokhov’s large office, decorated from walls to ceiling with Persian carpets, bear skins and weapons, Dolokhov sat in a traveling beshmet and boots in front of an open bureau, on which lay abacus and stacks of money. Anatole, in an unbuttoned uniform, walked from the room where the witnesses were sitting, through the office into the back room, where his French footman and others were packing the last things. Dolokhov counted the money and wrote it down. “Well,” he said, “Khvostikov needs to be given two thousand.” “Well, give it to me,” said Anatole. – Makarka (that’s what they called Makarina), this one will selflessly go through fire and water for you. Well, the score is over,” said Dolokhov, showing him the note. - So? “Yes, of course, so,” said Anatole, apparently not listening to Dolokhov and with a smile that never left his face, looking ahead of him. Dolokhov slammed the bureau and turned to Anatoly with a mocking smile. – You know what, give it all up: there’s still time! - he said. - Fool! - said Anatole. - Stop talking nonsense. If only you knew... The devil knows what it is! “Come on,” said Dolokhov. - I'm telling you the truth. Is this a joke you're starting? - Well, again, teasing again? Go to hell! Eh?...” Anatole said with a wince. - Really, I have no time for your stupid jokes. - And he left the room.
Clumsiness
Indeed, people weighing over 120 kg of muscle mass are usually not as agile and fast as 60-80 kg turnstile men. After all, carrying such a weight on yourself, no matter what it comes from, is not so easy. But often they are still more dexterous and faster than ordinary people with beer bellies who have never played any sports.
And this does not concern everyone - there are bodybuilders who, in parallel with pumping up their muscles, perform stretching exercises and development of functional qualities, so this problem does not concern them.
In addition, the issue of “clumsiness” is relevant only for professional bodybuilders with very large body weights. Ordinary amateur athletes weigh “only” 80-100 kg and for them there is no problem of insufficient agility.
Mental capacity
The level of IQ, general erudition and intelligence has nothing to do with the sport a person plays. Among the turnstile men there is the same percentage of stupid people as among the jocks. Both among bodybuilders and among turnstile men there are scientists, doctors of science, businessmen, and politicians. There are no more and no less of them than among other people. But there are two immutable truths:
- You can't achieve world records in sports by being stupid. Sport is not about carrying bags, you need to think!
- An intelligent person will never speak in absentia about the mental abilities of others, and even more so will not label someone else “dumb” just because he looks “like a closet.”
Now we have given enough arguments to explain the dislike of jocks for turnstiles. But this does not mean that all turnstile men are like this. There are also normal ones who respect other sports. Likewise, there are also jocks who understand this and therefore speak respectfully of the turnstile men’s activities. ___ But what can I say, if even the most famous turnstile athlete in the CIS, Denis Minin, uses strength exercises in his training, including the bench press, dips and pull-ups with weights. This gives us hope that the two opposing camps will someday make peace and understand each other.
Brock Lesnar. Wrestling star and former UFC champion
Brock is a monster who knew exactly how to apply power to life. He is a wrestler, former wrestler, MMA fighter and American football player. At the same time, he was good almost everywhere: he became an 11-time WWE world champion, a former UFC heavyweight champion, an NJPW (Japanese wrestling federation) world champion and an NCAA wrestling champion. He is now the only person in history to have won titles in each of these organizations.
Brock rose to prominence in the WWE, where he joined in 2000 as a wrestling champion with a 106-5 record in just four years of college. 2 years later, Lesnar made his debut on Raw television and, thanks to his impressive appearance and in-ring performances, quickly rose to fame in wrestling, becoming a full-fledged star.
In 2006, Brock attended the K-1 HERO's kickboxing tournament, where he entered the ring and declared that he wanted to fight. In the summer of the same year, he signed a contract with K-1, where he was supposed to fight with the giant Korean Hong Man Choi. Choi was injured and was replaced by another Korean, Kim Min Soo, who eventually lost to Brock by knockout in the first round.
A year later, Lesnar made his debut at UFC 81 and lost to Frank Mir via kneebar. Brock's next opponent was supposed to be the promotion's first heavyweight champion, Mark Coleman, but he withdrew before the fight due to injury. Heath Herring came in as a replacement, and Lesnar easily outlasted him over the course of three rounds. This victory brought Brock the status of a contender for the heavyweight title (very quickly!), and at UFC 91 he took the championship belt, knocking out the legendary Randy Couture in the second round.
Lesnar defended his title twice, knocking out Frank Mir at UFC 100 and then knocking out Shane Carwin. Brock lost the belt at UFC 121 when Cain Velasquez knocked him out in the first round. A year later, Lesnar tried to make a comeback, but lost to Alistair Overeem, after which he retired from MMA.
After 5 years, Brock decided to return, fought with Mark Hunt at UFC 200 and even won on points, but later failed a doping test. Lesnar was planning a fight against Daniel Cormier when he became champion, but still remained in WWE.
