Crossfit: 5 advantages and 5 disadvantages of this type of training
First of all, I would like to present this new sports modality that in our times has become fashionable.
5 advantages and 5 disadvantages of the 'Crossfit'
The "Crossfit", although it seems a revolutionary new practice, has been training in this way for dozens of years in highly demanding individual sports such as athletics or contact sports such as boxing.
The Crossfit does not stop being a high intensity activity with reduced breaks , which allows us to initially work on anaerobic alactic system, when our ATP, the most basic energy obtaining system and the fastest obtaining one, is exhausted, we start to work with glucose through the anaerobic lactic system and oxidize the glucose of the body, and at the end of the training there is a great activation of the aerobic system with the oxidation of fats. Keep in mind that these systems are always active only at certain times working in large ranges.
The 5 advantages of Crossfit
1. Work of the cardiorespiratory system
Even being an activity of great impact of force, we forced the cardiorespiratory system to work to its limit with the consequent modification in our physiological system.
Higher production of erythropoietin , which is responsible for the production of red blood cells and these transport oxygen, therefore greater oxygen transport to our muscles and organs.
Growth of the cavities of the heart and a hypertrophy of its walls, with this we achieve that in each beat more blood moves, since the heart can pump more blood in each beat and the blood circulates with more force. With this we can notice that our pulsations at rest have decreased and when we begin sports practice they rise more quickly.
The alveoli that are responsible for the oxygen uptake we breathe work more efficiently, therefore they capture a higher% than sedentary people.
The exchange zone works with more effectiveness, this zone is the one that exchanges the substances in this case oxygen and carbon dioxide between the venules with the pulmonary system.
2. Resistance to muscle fatigue
Not only do we get resistance to physiological fatigue, but also to muscle fatigue. When working at a muscle level repeatedly and with short or no breaks we get our muscles to get used to high intensity work maintained over time, taking into account that the higher the intensity the shorter the time we can maintain the effort.
3. Muscle hypertrophy
For people who may be interested, with the Crossfit we get a slight sarcoplasmic hypertrophy and a moderate sarcomeric hypertrophy so that we will have a rather rocky hypertrophy since many myofibrils are contained by muscle fiber.
4. Fat burning
When performing this type of training we will get that after training the body is burning more calories in the form of fat, up to 72 hours later.
5. Butt motivation
A sport that allows us to measure ourselves and improve ourselves in each session, will keep us motivated and fulfilled, with this we will release even more endorphins than doing another type of sport and will allow us to maintain a more stable psychological state.
The 5 drawbacks of the Crossfit
Some of the exercises that are proposed can be highly damaging to our joints and even to the tendons.
2. Special material
Not all gyms are adapted for a crossfit job, it depends the city will cost us to find a gym that allows us to train this modality. So, if your goal is to train crossfit, you must go to a center that allows you to develop your routines with full guarantee.
3. Non-specialized assistants
In many centers, it is not usual practice how to perform the basic exercises of weight lifting, such as clean & jerk, and when they are performed incorrectly they can be highly damaging to the spine, so you have to try to put yourself in the hands of a good professional.
If we do not monitor workloads, or who directs us does not take them into account, it is easy to fall into overtraining: that is, we have exceeded the exercise load limit that our body can assimilate. If we notice headaches, loss of appetite or insomnia, I recommend taking a week of total rest to regain strength and avoid injuries or health problems.
5. Wear and danger of breaking
By taking the body to the limit, in the last minutes of training our intramuscular and intermuscular coordination will be impaired, this leads to poor execution of movements and exercises, therefore a danger to our back, muscles and joints.Try to put the exercises of great loads at the beginning of the training to avoid this inconvenience.
