A team of researchers from the Polytechnic University of Madrid and the Spanish National Research Council (CSIC) has conducted an analysis of thoracic capacity in 22 athletes. The purpose is to understand how thoracic expansion during exercise can improve performance and prevent injuries. The study reveals that training not only increases respiratory efficiency but also promotes cardiovascular endurance and reduces muscle fatigue. This translates into faster recovery after exercise. Athletes underwent incremental running tests in which their thoracic kinematics were recorded. Variations in thoracic expansion were observed depending on the intensity of the exercise, with distinct patterns in different phases of exertion. Implications for injury prevention: The study's findings underscore its relevance in the prevention of physical injuries. They provide crucial data for designing safer and more efficient training programs, as well as for addressing respiratory pathologies related to physical activity.

The work also suggests that the results can have a significant impact on the diagnosis and treatment of respiratory disorders, improving the quality of life of people with chronic lung diseases and promoting rehabilitation strategies adapted to individual needs.

Training to Improve Thoracic Expansion

Diaphragmatic breathing and thoracic mobility exercises are the most effective for improving thoracic expansion, as they strengthen the intercostal muscles and promote greater rib cage amplitude. Techniques such as thoracic rotation and elastic band extension also stand out for their ability to increase flexibility and motor control in this area.

Diaphragmatic Breathing.Inhale deeply through your nose, expanding your abdomen and lateral ribs, then exhale slowly through your mouth. This exercise improves lung capacity and rib cage expansion by activating the diaphragm. Perform it lying down with your knees bent for greater initial effectiveness.

Mobility with stretching. Exercises such as chest flyes against a wall or cat-cow stretches on all fours open the chest and extend the thoracic spine. Accompany them with controlled breathing to enhance scapular activation. Scapular flexion-extension with a resistance band focuses the movement on the ribs.

Rotation and yoga. Seated thoracic rotation, inhaling and slowly rotating, develops pain-free rotational mobility. Yoga poses such as cobra or camel stretch the chest and improve expansion.

Thoracic expansion between beginner and professional athletes

Recent studies indicate that there are no significant differences in thoracic expansion between beginner and professional athletes at the same exercise intensity.

Observed patterns. Identification of a “mirror pattern”: superior anteroposterior and inferior mediolateral diameters expand more at the beginning of the effort, while superior mediolateral and inferior anteroposterior diameters expand more in the final phases. This behavior was repeated in all groups regardless of level.
