Doctor on Intense Training Trend: Extremes Are Hardest for the Body to Adapt To

The human body is not designed for prolonged sitting and monotonous movements, yet this has become a dominant lifestyle. Dr. M. Ambraška, a sports medicine physician, observes that extended inactivity affects the musculoskeletal system, overall well-being, energy balance, sleep quality, and emotional state. This decline in physical preparedness is now evident even among young people and athletes, with some struggling to perform basic exercises previously considered standard.

The human body is not adapted to prolonged sitting and monotonous movements, but this is precisely the model that is becoming dominant.

The situation is exacerbated by fragmented movement patterns, where long periods of inactivity are abruptly compensated with intense training. Ambraška explains that the body finds it most challenging to adapt to sudden physical contrasts. This pattern significantly raises the risk of overexertion, injuries, and inflammatory reactions.

Even when working with high-performance athletes, we see gaps in basic physical preparedness. Some young people find it difficult to perform elementary exercises that were previously considered completely standard.

While high-intensity training formats like 'Hyrox' have gained popularity, Ambraška notes a positive trend of increased interest in endurance, functional movement, and overall physical fitness. However, this also leads to situations where physical load exceeds the body's actual capabilities. He points out that while the exercises might seem simple, they demand significant physiological adaptation, including a robust cardiovascular system, endurance, and fatigue management. The problem arises when individuals assess their readiness based on motivation rather than actual physical preparedness.

The most difficult thing for the body to adapt to is sudden physical contrasts. A person moves minimally for most of the week and then tries to do a very intense workout in a short period. In such situations, the risk of overloads, injuries, and inflammatory reactions increases significantly.

Despite these risks, Ambraška emphasizes that high-intensity training itself is not inherently problematic. For many, it serves as a strong motivator for increased physical activity and goal setting. The key is a gradual increase in load that matches individual preparedness. Therefore, objective assessment of the body's condition is crucial, especially when individuals independently intensify their physical activity. Functional tests and physical capacity assessments can help individuals understand their body's response to exertion and identify personal limits, the ignorance of which often leads to overexertion.
