Summary
In-line skating offers great cardiorespiratory benefits. The double pole technique is the most economical, requiring 12% less oxygen uptake than other methods, making it ideal for fitness training.
Area of Science:
- Exercise Physiology
- Biomechanics
- Sports Science
Background:
- In-line skating is a popular recreational and conditioning activity.
- Understanding the physiological demands of different in-line skating techniques is crucial for optimizing training.
Purpose of the Study:
- To evaluate the physiological responses to three distinct in-line skating techniques.
- To compare the energy cost and exercise intensity across different techniques.
Main Methods:
- Ten subjects performed in-line skating on a flat track using double pole, conventional (no poles), and V1 skate techniques.
- Physiological responses, including oxygen uptake, were measured at velocities ranging from 14.6 to 18.0 km.h-1.
Main Results:
- The double pole technique showed the greatest economy, with oxygen uptake 12% lower than conventional or V1 skate techniques (p < 0.05).
- Conventional and V1 skate techniques elicited 68-90% of maximum oxygen uptake for average fitness individuals, suitable for cardiorespiratory training.
- Mechanical efficiency for double poling was estimated at approximately 18%.
Conclusions:
- The double pole technique is more energy-efficient for in-line skating.
- In-line skating, particularly with conventional and V1 techniques, can provide adequate cardiorespiratory training stimulus for average fitness individuals.
- Highly fit individuals may require advanced training strategies like uphill intervals or higher velocities to achieve desired training effects.
