Summary
Fin swimming may delay anaerobic metabolism activation compared to cycling. This study found a depressed cardiopulmonary response during fin swimming, suggesting delayed anaerobic response in muscles.
Area of Science:
- Exercise Physiology
- Sports Science
- Human Physiology
Background:
- Literature suggests fin swimming may delay anaerobic metabolism activation compared to dry-land exercise.
- Understanding the physiological responses to fin swimming is crucial for optimizing training and performance.
Purpose of the Study:
- To investigate the hypothesis that fin swimming delays anaerobic metabolism activation.
- To compare physiological responses during incremental fin swimming and dry-land cycling.
Main Methods:
- Thirteen participants performed incremental fin swimming and maximal cycloergometer exercise.
- Measurements included heart rate (HR), ventilation (VE), tidal volume (VT), oxygen uptake (VO(2)), and carbon dioxide production (VCO(2)).
- Ventilatory threshold and maximal oxygen uptake (VO(2)max) were determined.
Main Results:
- Fin swimming showed an elevated or absent ventilatory threshold compared to cycling.
- Maximal HR was lower (-18%) and maximal oxygen pulse (VO(2)/HR) was higher (+20%) during fin swimming.
- Maximal carbon dioxide production (VCO(2)) was lower (-17%) in fin swimming, with reduced VE, VT, and HR variations for a given VO(2) increase.
Conclusions:
- Fin swimming appears to delay the onset of anaerobic muscle metabolism.
- An attenuated chemoreflex drive from muscle metabolites may explain the blunted cardiopulmonary response observed in fin swimming.
- These findings have implications for understanding the physiological demands of fin swimming.

External and Internal Respiration
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...
Breathing
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
Gas Exchange and Transport
Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.
Respiratory Capacities
Respiratory capacities are crucial indicators of lung function, representing the maximum amount of air an individual's respiratory system can handle during various breathing phases.
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

Pulmonary Ventilation: Inhalation
Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.

Respiration and Gaseous Exchange
The intricate interplay between the cardiovascular and respiratory systems is crucial for efficiently transporting respiratory gases throughout the body. Let us explore the cardiovascular system's multifaceted functions, emphasizing its pivotal role in gas exchange.
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves the...
