Causes of performance decline and training blocks

A decline in performance rarely happens overnight. It's usually due to a combination of factors, including nutrient deficiencies, hormonal imbalances, overtraining, stress, or an unbalanced diet . If you're not making progress despite training, tire more easily, or are injured more frequently, deficiencies in magnesium, iron, vitamin D, or B vitamins, as well as thyroid or stress hormone levels, could be key factors.

Genetic factors also influence your training ability: Some people have a higher tendency towards muscle fatigue, slower recovery, or a lower VO2max potential. Others, however, build muscle faster or burn fat more efficiently.

A DNA and blood test will show you exactly which factors are limiting your performance – so that you can take targeted countermeasures.

Understanding your body in everyday training: Energy, regeneration & resilience

Athletic success is based on a finely tuned interplay of energy supply, regeneration, muscle function, and mental resilience. If any of these areas become unbalanced, it directly impacts your performance.

An analysis of your genetic predisposition helps you understand how well your body breaks down lactate, the distribution of your muscle fiber types, and which dietary patterns best support your energy levels. At the same time, a blood test reveals whether important markers such as vitamin D, iron, magnesium, omega-3 fatty acids, or inflammation levels are creating optimal conditions – or silently holding you back.

This way you can tailor training, nutrition, supplementation and regeneration precisely to your body.

Optimize your training results with a blood test – easily done from home

A blood test for sports and fitness not only shows you whether you're lacking important nutrients – it also explains why your performance has stagnated or why you don't feel fit despite training. Vitamin D influences muscle strength, iron is crucial for oxygen transport, magnesium ensures muscle function and regeneration, while omega-3 and inflammatory markers show how well your body reacts to stress.

With a mybody® blood test, you can conveniently check all these values ​​from home. The capillary blood sample is analyzed in the laboratory, and you receive an easy-to-understand results report with clear recommendations for action: more energy, better recovery, fewer injuries, and more efficient training results.

This is how you train smarter – not harder.

What are the consequences of nutrient or performance deficiencies for athletes?

Nutrient deficiencies have a particularly strong impact on physically active people. They can lead to exhaustion, decreased performance, increased susceptibility to injury, muscle weakness, poor recovery, and even hormonal imbalances.

An iron or vitamin B12 deficiency reduces your endurance and workload capacity, a vitamin D deficiency weakens muscles and bones, and magnesium or potassium deficiencies cause muscle cramps and fatigue. Hormonal imbalances such as an unbalanced TSH level or elevated stress hormones can also lead to training plateaus or sleep problems.

If left untreated, these deficiencies prolong recovery times, weaken the immune system and increase the strain on muscles and joints – which can lead to overload and injuries in the long term.

Why does my diet affect my performance and recovery?

Your diet determines how much energy is available to your body, how quickly you recover, and how well your muscles adapt to training. Carbohydrates provide quick energy, proteins support muscle growth and repair, healthy fats regulate hormones, and micronutrients keep your metabolism and nervous system stable.

When certain vitamins or minerals are lacking, your body operates below its potential: you feel more frequently fatigued, your muscles regenerate more slowly, and you can utilize fewer training stimuli. At the same time, dietary habits, gut flora, and genetic predisposition influence how well you can absorb nutrients in the first place.

With an individual analysis of DNA and blood values, you can identify which nutritional strategy best supports your performance – for more energy, strength and endurance.
