Cyclists with lower VO2max utilize distinct thoracoabdominal breathing patterns (THA) during exercise, increasing abdominal contribution and decreasing rib cage use compared to higher VO2max athletes. This highlights performance-related breathing strategies.
Area of Science:
- Sports Science
- Physiology
- Biomechanics
Background:
- Thoracoabdominal breathing pattern (THA) is influenced by exercise intensity and individual factors.
- Understanding THA variations can offer insights into athletic performance levels.
Purpose of the Study:
- To investigate the thoracoabdominal breathing patterns (THA) in cyclists across different performance levels.
- To analyze how increasing exercise intensity affects THA in professional cyclists.
Main Methods:
- Fourteen male professional cyclists underwent resting breathing tests and a step-incremental cycling test.
- Physiological responses were measured, and cyclists were grouped by VO2max (Higher vs. Lower).
- An optoelectronic system recorded THA, analyzing the contribution of the superior thorax (ST), inferior thorax (IT), and abdomen (AB) to tidal volume.
Main Results:
- Higher VO2max cyclists maintained a stable breathing compartment contribution throughout exercise intensity.
- Lower VO2max cyclists showed increased abdominal (AB) contribution and decreased rib cage (ST + IT) contribution at ventilatory thresholds.
- Significant differences in coordination between thoracic and abdominal compartments were observed between the performance groups.
Conclusions:
- Athletes with different performance levels exhibit distinct thoracoabdominal breathing patterns.
- Breathing mechanics, specifically the interplay between thoracic and abdominal compartments, may differentiate cyclist performance levels.

Muscles of the Thorax
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...
Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...
Mechanism of Breathing I: Inspiration
The respiratory system, an essential network for breathing, comprises the conducting and respiratory zones, each playing a crucial role in the overall process of respiration. Let us explore the detailed mechanism of inspiration, or inhalation, which is the first phase of the respiratory cycle.
Pathway of Air during Inspiration
During inspiration, air enters our body through the nose or mouth and moves through the conducting zone,...
