The evolution of athletic performance has transitioned from mere observation toward a massive integration of metrics aimed at deciphering the athlete's physiological state. In this context, the subjective perception of the athlete, traditionally gathered through wellness questionnaires, has proven to be a valuable tool, yet one intrinsically conditioned by the individual's responses. The current challenge lies in validating these individual sensations through technologies that provide objective data. Infrared thermography stands as a vital complement, allowing a subjective opinion to be transformed into a clinical decision backed by thermal data.

The exclusive use of questionnaires presents a systemic vulnerability known as self-report bias, where factors such as the desire to compete or a lack of body awareness can distort the response. By integrating thermography, a control system is established that directly correlates questionnaire results with specific anatomical regions. This methodology makes it possible to identify whether sensations or discomfort coincide with alterations in detected asymmetries, providing the coaching staff with a risk "traffic light" far more reliable than a simple questionnaire.

Recent scientific evidence, supported by studies analyzing the association between physical demands and skin temperature, suggests an inversely proportional relationship between thermal asymmetries and perceived well-being. An organism presenting a balanced thermal map is typically associated with states of well-being, optimal rest, and low levels of systemic stress. Conversely, the appearance of significant asymmetries in key muscle regions serves as an early indicator of inflammatory processes, overloading, or incomplete recovery. This correlation allows strength and conditioning coaches to anticipate issues and establish timely interventions for the athletes.

The implementation of this technological duo varies significantly according to the athlete's profile, adapting to their maturity level and self-knowledge. For young or inexperienced players, thermography serves an essential pedagogical function, helping them understand their sensations and the importance of honest communication. For independent or veteran players who already possess advanced load management skills, the technology serves to fine-tune periods of greater imbalance. In both cases, the goal remains the same: to provide intuition with a metric support system that guarantees the professional's physical integrity.

Subjectivity is valid for understanding the player's psychology, but it becomes hazardous if it is the sole tool for load management. Thermography complements this approach. By crossing wellness questionnaire information with thermal profiling, analysts can detect inconsistencies that signal fatigue, allowing for tailored interventions. Having a comprehensive vision that combines the athlete's voice with physiological data represents a workflow that enhances decision-making and allows for an objective approach to the player, ultimately helping them improve their performance.
