Summary
Adding ankle or wrist weights during treadmill running increases energy expenditure and heart rate. Ankle weights produced a greater effect than wrist weights, enhancing training intensity and potential fitness gains.
Area of Science:
- Exercise Physiology
- Sports Biomechanics
Background:
- Ankle and wrist weights are sometimes used to increase exercise intensity.
- Limited research exists on their acute physiological effects during running.
Purpose of the Study:
- To investigate the acute physiological responses to treadmill running with added ankle and wrist weights.
- To compare the effects of weight placement (ankles vs. wrists) on physiological variables.
Main Methods:
- Eight physically active men performed treadmill runs at self-selected speeds.
- Four incremental loads (0, 1.6, 3.2, 4.8 kg) were applied equally to ankles or wrists.
- Measurements included energy expenditure, heart rate, blood lactate, and perceived exertion.
Main Results:
- Energy expenditure and heart rate increased linearly with added weight at both locations.
- Responses were significantly greater with ankle weights compared to wrist weights.
- Perceived exertion increased significantly with the heaviest weights (4.8 kg) at both ankles and wrists.
Conclusions:
- Ankle and wrist weights elevate training intensity and energy expenditure during running.
- Ankle weights are more effective than wrist weights in augmenting these physiological responses.
- This suggests potential for enhanced cardiovascular fitness and weight loss when using these devices.
