Summary
Offshore sailing involves isometric effort, but physiological measures show moderate energy output and minimal cardiovascular strain. This suggests sailing is a suitable aerobic recreational exercise.
Area of Science:
- Sports Science
- Exercise Physiology
- Cardiovascular Health
Background:
- Offshore sailing often requires maximal voluntary contraction (MVC) isometric efforts during rope hauling.
- Understanding the physiological demands of sailing is crucial for assessing its role as recreational exercise.
Purpose of the Study:
- To investigate the physiological responses to isometric effort in offshore sailing.
- To determine the cardiovascular load and energy expenditure associated with sailing activities.
Main Methods:
- Measurements of blood pressure, heart rate, VO2, and lactate accumulation were taken.
- Data were collected both on a boat and in a laboratory using a boat simulator.
Main Results:
- Sailing tasks resulted in moderate energy output.
- Lactic oxygen debt was found to be not relevant.
- Blood pressure remained largely unchanged due to the short duration of isometric efforts.
Conclusions:
- The cardiovascular load during sailing is not heavy.
- Sailing can be classified as an aerobic recreational exercise.
- The physiological demands are manageable for recreational participants.
