How to read blood test results: what changes when you are physically very active ?

When athletes undergo routine blood tests, several values often differ from the normal reference range. These differences usually reflect physiological adaptations to training, not pathology.
If you go to a general practitioner for a health check and a blood test, he or she may not always take into account or even ask about your level of physical activity. Your blood sample will be compared to a reference range, which is established on values that are found in the “general healthy population”. This includes sportive people but also people that do not exercise.
Regular intensive exercise requires a lot more from the body, in terms of energy and/or muscle synthesis. This translates into adaptations in the metabolic pathways, and several parameters in the blood test will show values that are not normally seen in the general population.

With this information, we want to point out that it is not always bad if you have some blood test results that are extra-ordinary. They may just be in an indication that you are exceptional when it comes to physical activity. But still, always consult with a health specialist and discuss your level and timing of exercise for a correct interpretation of blood test results, so that possible health hazards are not ignored.

Does having s*x affect athletic performance in men?

What does the Research Say?
• Testosterone & Hormones
Sexual activity does not significantly deplete testosterone levels in a way that would harm performance. On the contrary, abstaining too long might actually lower testosterone, making a man more irritable and distracted.
• Energy & Fatigue
A typical s*xual encounter burns about 100–300 calories, which has no significant effect on depleting energy reserves, unless done right before a demanding event.
However, if s*x leads to poor sleep (due to timing or emotional factors), then performance may suffer indirectly.
• Focus & Motivation
For some men, abstinence may increase aggression or focus, a placebo or psychological effect often exploited by boxers and martial artists.
Others may find reduced anxiety or improved sleep after s*x, which can aid performance.
________________________________________
Conclusion:
• Timing matters: the night before does not reduce performance, unless it affects sleep. However, having s*x 1 or 2 hours before an event, may cause mental fatigue or reduce aggression.
• Thus, the benefit or disadvantage of having s*x before a sports challenge depends mostly on psychology. Individual variation is huge: some may benefit from the relaxation, others might prefer to abstain for mental focus.
• Listen to your own body and mind: what works best for you matters most. Beliefs around s*x and performance can create placebo or nocebo effects. If an athlete believes that s*x hurts performance, it might, purely due to mindset.

ARE NUTS GOOD FOR MUSCLE BUILDING?
Yes, absolutely. Nuts have a high content in calories and fat, but when eaten in moderation, they provide many benefits for athletes. They are full of micronutrients that are essential for muscle repair and growth. The healthy fatty acids stimulate hormone production and nutrient absorption. Walnuts for instance, with a huge content in Omega-3, promote joint and bone health and reduce inflammation to speed up recovery. Pecans are also a very good source of omega-3. Almonds provide almost 50 % of the daily requirements for Vitamin E, which aids with muscle membrane repair.
It is important though to limit the portions and combine with lean sources of protein. Special care is to be taken with Brazil nuts: they contain an enormous amount of selenium, which is advantageous to boost testosterone and muscle growth. But you should not eat more than one nut per day to avoid selenium toxicity. Moderation is the key!

PROTEIN INTAKE CEILING – how much protein per meal can your body take?
It has long been said that you cannot digest more than 30 grams of protein in one meal. This idea of a “protein intake ceiling” derives from outdated research. Because scientists found higher nitrogen loss in the urine with higher protein intakes, they simply concluded that the extra protein was wasted and useless. We now know that this is not correct: protein metabolism is far more complex.
When you eat protein, your body breaks it down into its constituent amino acids and uses those to make its own proteins. When you eat lots of protein, your body can afford to replace more of its damaged proteins: protein synthesis and protein breakdown (protein turnover) increases. The raised level of urinary nitrogen therefore does not reflect a waste of eaten protein, but it is the excretion of damaged proteins, that have been replaced by new proteins.
The notion of a “protein ceiling” was also mistakenly confirmed by a study about the body’s muscle protein synthesis (MPS) response to different intakes of protein. They found that, in healthy adults, eating 90 grams of protein from 90% lean beef didn’t increase MPS more than 30 grams did.
But your body doesn't use dietary protein only to make muscle, or even only to make other proteins. Muscle tissue accounts for only 25–30% of whole-body protein turnover. The nitrogen from the dietary protein’s amino acids is also used to synthesize important nonprotein molecules, such as purines and pyrimidines, the building blocks for nucleic acids such as DNA and RNA. Excess amino acids can also be oxidized for energy.
These recent findings have also shifted the reference range of total protein intake per day. Where FDA still claims 0,8 grams of protein per kg of body weight is enough, this value is highly criticized by experts who consider it the bare minimum for sedentary young people. Physically active people and ageing individuals need far more protein to sustain muscle growth and prevent sarcopenia. Institutions like ISSN (international society of sports nutrition) for instance recommend intake of 2,2 grams/kg per day for active healthy persons, which can even safely be raised to 3 grams/kg/day.
CONCLUSION: Your body does not discard excess amino acids. Eating more than 30 grams of protein per meal does have benefits and is not wasted. Apart from stimulating muscle synthesis, it promotes repair and maintenance of other important molecules and tissues, keeping you strong, healthy and youthful.

DOES TRT MAKE A MAN INFERTILE?
Thinking about starting Testosterone Replacement Therapy? There is one important thing to consider: exogenous testosterone injections reduce your fertility.
For men who want to increase their testosterone level, but don´t want to abandon the idea of having (more) children, there is an alternative option: increase your own natural testosterone production.

HOW DOES IT WORK AND WHY IS THE OUTCOME DIFFERENT:
The body´s mechanism of testosterone production is controlled by receptors in the body that inform the brain how much hormones are circulating. When there is a high level of hormones circulating in your blood, the receptors send signals to the hypothalamus and the pituitary gland stops liberating LH (Luteinizing Hormone) and FSH (Follicle stimulating hormone) into the bloodstream.
The go**ds (te**es) have receptors for LH and FSH. They need LH to stimulate the production of testosterone and FSH to stimulate the production of s***m.

With TRT you are directly injecting testosterone, which the receptors in your body detect and send signals to the brain to stop releasing LH and FSH in the bloodstream. Without these, the go**ds stop their production of testosterone and s***m. The testosterone from the injection improves s*xual function, but the go**ds remain inactive. Semen with little or no s***m leaves the man infertile.

The alternative treatment consists of an oral supplementation with a compound that attaches to the hormone receptors in your body and blocks them from sending signals to the brain. The pituitary gland does not receive the information that there are enough hormones in the blood. Therefore, it will start releasing more LH and FSH that stimulate the go**ds to produce more Testosterone and more s***m. Result: higher level of testosterone and better quality of semen with increased fertility.

ARE YOU NOT FEELING LIKE YOURSELF ANYMORE?
If you are reading this, you have probably been reflecting on your testosterone levels. Maybe testosterone is not a topic of much interest for you. But you may have observed a decrease in energy, low libido, diminished muscle mass, sleep disturbances, feelings of depression, anxiety, reduced semen volume or erectile dysfunction (ED). These issues may be linked to declining testosterone levels, a situation that is quite prevalent, as testosterone levels typically decrease with age in men. As time passes, symptoms tend to get worse. Many men simply accept the situation and don´t do anything about it. But it does not need to be like this. You can reverse the situation with a very simple solution.

Testosterone makes you aggressive… truth or myth?
This is a question often debated, but the science is clear: Testosterone on its own does not make you aggressive.
Aggression has a complex foundation and is determined by social, environmental, genetic and psychological factors. What can be expected though, if a person is already prone to aggressive behaviour due to one of these underlying causes, the administration of exogenous Testosterone can increase motivation towards aggression. In healthy men, higher testosterone levels are linked to more confidence, improved mood and social assertiveness, but not aggression. Low Testosterone, on the other hand, can make a man grumpy and cause irritability, depression, anxiety and lack of motivation.

Exercise helps to grow muscles. Testosterone helps to grow muscles. No doubt about that! But how much does each of them matter ? We have done the research and here are the numbers: on average, a man weighing 70 kg that does not exercise and has a testosterone level in the lower range of physiological value can gain approximately 6 kg of lean muscle mass in 10 weeks time if he starts resistance training in combination with Testosterone treatment.

PROPER NUTRITION IS ESSENTIAL FOR A HEALTHY HORMONE BALANCE
Hormones are biochemical messengers in the body that communicate with various organs, skin, and muscles. They are integral to regulating numerous physiological functions, such as metabolism, growth, mood, s*xual health, and sleep patterns. The human body produces approximately 50 distinct types of hormones, all of which, along with the tissues responsible for their production, constitute the endocrine system. To promote optimal hormone function, it is vital to ensure adequate nutrient intake through a balanced diet and, when necessary, supplementation. Vitamins and minerals play a supportive role in the normal functioning of the endocrine system and the maintenance of hormonal equilibrium. By integrating appropriate nutrients into one’s diet, individuals can effectively support their hormonal health.
Verelst Health & Performance Clinic provides supplements that help you keep a healthy hormone balance.

The impact of low testosterone may start to manifest as early as a man's 30s. Initially, the symptoms can be quite subtle and may go unnoticed, but they can eventually escalate to a level that significantly influences various facets of a man's life and overall well-being.
It's not uncommon for us to encounter patients who have endured their struggles quietly for years, unaware that a straightforward solution exists. We've witnessed remarkable improvements in men in their 60s and 70s. Many older patients experience significant transformations in their health and overall wellbeing once they begin therapy, often wishing they had taken this step earlier.
