CrossFit is considered one of the most "squeeze" sports for the majority of the population. Often in the community phrases are heard, such as: "after training, nausea comes" or you hear complaints about chronic overtraining of the body. But such an aspect as the temperature after exercise is practically not considered, since such a symptom is considered almost the norm. Is it so? Let's consider this issue in all details.
Why does it arise?
Could there be a fever after exercise? If it rises, is it bad or normal? To answer these questions, it is necessary to study the whole complex of processes occurring with the body during training.
Metabolic acceleration
In the process of working with the projectile, we make much more movements than in everyday life. All this leads to the acceleration of the heart and the acceleration of metabolism. The increased speed of the main processes leads to a slight increase in temperature.
Heat generation
During a workout, to perform certain actions (lifting the barbell, running on the treadmill), we need a huge amount of energy, which is released from nutrients. Burning off of nutrients always occurs with the release of heat, which is regulated by additional sweating. But the body doesn't stop burning nutrients after exercise, which can lead to a slight rise in temperature during the recovery period.
Stress
Training itself is a destructive factor. Efforts during exercise physically tear our muscle tissues, forcing all systems to work to the limit. All this leads to stress, which can lead to weakening of the immune system. If the loads were excessive, or the body was fighting infection in the background, then the increase in temperature is a consequence of the weakening of the body.
Impact of third-party drugs
Modern man uses a huge number of different additives. This includes fat burning complexes. Starting with innocent L-carnitine and ending with killer drugs that increase performance in training.
Nearly all fat-burning and pre-workout supplements aimed at burning fat as their primary fuel can affect body temperature. This can be done in two ways:
- Increase your basal metabolic rate. In fact, this raises the temperature to 37.2, as a result of which the body tries to restore a balance state, for which it spends a lot of energy (including fat).
- The transition to the fat depot by increasing the load on the cardiac muscle group.
In the first, in the second case, triglycerides are used as an energy source, which, when burned, release 8 kcal per g against 3.5 kcal per g derived from glycogen. Naturally, the body is physically unable to process such a volume of energy at once, which leads to additional heat transfer. Hence the effect of increasing body temperature after exercise and after it.
In most cases, individually, all of these factors cannot seriously change the body temperature, however, in aggregate, in some people, they can cause a significant increase, up to 38 degrees and above.
Can you exercise with a temperature?
It all depends on why you have a post-workout fever. If this condition is associated with a weakening of the immune system, then training is categorically not recommended, since training is an additional stress for the body. Like any stress, it has a temporary depressing effect on the body, which can lead to an exacerbation of the disease.
If you are shivering from overload in the body, then here you need to pay attention not only to the level of stress and temperature, but also to the complex of drugs that you use.
In particular, an increase in temperature may result from:
- taking a pre-workout complex;
- caffeine intoxication;
- the effect of fat burning drugs.
In this case, you can train, but avoid a serious power base. Instead, it is better to devote your workout to aerobic complexes and serious cardio workout. In any case, before the next workout, reduce the dosage of the supplements used to reduce the manifestation of negative side factors.
If we are talking about a slight rise in temperature (from 36.6 to 37.1-37.2), then this is most likely just a thermal effect from the resulting load. To reduce the temperature in this case, it is enough to increase the amount of fluid consumed between approaches.
How to avoid?
To achieve sports progress, it is important not only to understand why the temperature rises after training, but also to know how to avoid such a situation.
- Drink plenty of fluids during your workout. More fluid - more intense sweating, less likely to rise in temperature.
- Reduce your pre-workout caffeine intake.
- Do not use fat burning drugs.
- Keep a training diary. It avoids overtraining.
- Reduce physical activity while exercising.
- Recover fully between workouts. This will reduce the negative factor of training stress.
- Reduce your protein intake. This will help in the event that you significantly exceed the recommended dose, which leads to inflammatory processes in the liver and kidneys.
We fight overheating of the body
If after training you need to go to a business meeting, or it takes place in the morning, you need to know how to effectively bring the temperature down to acceptable limits.
Method / means | Operating principle | Health safety | Impact on the result |
Ibuprofen | Non-steroidal anti-inflammatory drug: relief of inflammation can bring down the temperature and get rid of headaches. | When consumed in small doses, it has low toxicity to the liver. | Reduces anabolic background. |
Paracetamol | An antipyretic agent with an analgesic effect. | It is extremely toxic to the liver. | Creates additional stress on internal organs. Reduces anabolic background. |
Aspirin | Antipyretic, non-steroidal anti-inflammatory. Has a number of side effects that are incompatible with taking on an empty stomach or as a preventive measure immediately after exercise. | It has a thinning effect, it is not recommended to use it after serious exertion. | Increases catabolism, leading to muscle loss. |
Warm lemon tea | Suitable if the rise in temperature is a consequence of increased stress. Vitamin C stimulates the immune system, hot liquid induces perspiration, which lowers the temperature. | The tannin in tea can lead to increased stress on the heart muscle. | Vitamin C stimulates faster recovery. |
Cool shower | Physical cooling of the body allows you to temporarily return the body temperature to normal. Not recommended in case of overtraining or the first sign of a cold. | Can lead to colds. | Accelerates recovery processes, reduces the effect of stagnation of lactic acid in muscle tissue. |
Rubbing with vinegar | An emergency means of lowering the heat from 38 and above. Vinegar interacts with the sweat glands, causing a thermal reaction, which at first briefly raises the temperature and then sharply cools the body. | An allergic reaction is possible. | Does not affect. |
Cool water | Physically cools the body by a fraction of a degree. It helps in cases where the temperature is caused by dehydration and increased metabolism, is considered an ideal remedy. | Absolutely safe | Not affected except during drying periods. |
Outcome
Can the temperature rise after exercise, and if it does rise, will this be a critical factor? If you measure your temperature 5-10 minutes after training, there is nothing wrong with a slight increase in readings. But if the temperature begins to rise later, this is already a signal from the body about overload.
Try lowering the intensity of your workouts or avoiding fat burning complexes. If the rise in temperature after training the next day has become constant, you should think about completely revising your training complex or even consult a doctor.
