First of all, I would like to introduce this one new sport which nowadays has become fashionable.
5 advantages and 5 disadvantages of ‘Crossfit’
“Crossfit”, although it seems a new and revolutionary practice, has been training for decades in highly demanded individual sports such as athletics or in contact sports such as boxing.
Crossfit is still one of them high intensity activity with reduced breaks, Which initially allows us to work the anaerobic alactic system, when our ATP, the most basic energy system and the fastest obtaining system, is exhausted, we started to work with glucose through the anaerobic lactic system and oxidizing glucose at the end of training, there is a great activation of the aerobic system with the oxidation of fats. It should be noted that these systems are only always active at certain times, they operate in large ranges.
The 5 advantages of Crossfit
1. Work of the cardiorespiratory system
Although this is a high impact activity, we force the cardiorespiratory system to function at its limit with the consequent modification of our physiological system.
Higher production of erythropoietin, Which is responsible for the production of red blood cells and these carry oxygen, thus increasing the transport of oxygen to our muscles and organs.
Growth of the heart chambers and enlarged walls, which allows us to move more blood with each beat, because the heart can pump more blood with each beat and the blood circulates more strongly. With this, we can notice that our resting heart rates have decreased, and when we started to exercise, they increase faster.
The alveoli that are responsible for capturing the oxygen we breathe work more efficiently to capture a higher percentage than sedentary people.
The exchange zone works most efficiently, this zone is the one which exchanges substances in this case oxygen and carbon dioxide between the venules with the pulmonary system.
2. Resistance to muscle fatigue
Not only have we achieved resistance to physiological fatigue, but also to muscle fatigue. By working on a muscle level repeatedly and with short or no breaks, we accustom our muscles to high intensity work maintained over time, keeping in mind that the greater the intensity, the longer the time. will be low. What we will be able to maintain the effort.
3. Muscle hypertrophy
For people who might be interested, with Crossfit we get mild sarcoplasmic hypertrophy and moderate sarcomeric hypertrophy, so we will have hypertrophy rocky enough to contain lots of muscle fiber myofibrils.
By performing this type of training, we will achieve that after training, the body burns more calories in the form of fat, up to 72 hours later.
5. Top motivation
A sport that allows us to measure ourselves and to surpass ourselves in each session, will keep us motivated and accomplished, with this we will release even more endorphins than doing any other type of sport and will allow us to maintain a more stable psychological state.
The 5 disadvantages of Crossfit
Some of the exercises offered can become very harmful to our joints and even to the tendons.
2. Special material
Not all gyms are suitable for CrossFit work, it depends on the city it will cost us to find a gym that allows us to train this modality. So if your goal is to train for CrossFit, you should go to a center that allows you to develop your routines with full guarantee.
3. Non-specialized assistants
Many centers don’t usually practice how to perform basic weight lifting exercises such as clean & jerk, and when not performed properly they can be quite harmful to the spine, so try to have them done by a good one. professional.
If we don’t monitor workloads, or if those in charge don’t take them into account, it is easy to fall into overtraining: that is, we have exceeded the limit exercise load that our body can assimilate. If you notice migraines, loss of appetite or insomnia, I advise you to take a week of total rest to regain your strength and thus avoid injury or health problems.
5. Wear and risk of breakage
By bringing the body to the limit, in the last minutes of training our intramuscular and intermuscular coordination will be reduced, this leads to poor execution of movements and exercises, thus endangering our back, muscles and joints. Try to put the exercises on a high load at the beginning of the workout to avoid this inconvenience.
