The effect of ergometer design on rowing stroke mechanics

Area of Science:

• Sports Science
• Biomechanics
• Ergonomics

Background:

• Rowing ergometers are crucial training tools for athletes.
• Ergometer design can influence rowing technique and performance.
• Understanding these effects is key to optimizing training.

Purpose of the Study:

• To analyze the effect of different rowing ergometer designs on power delivery.
• To investigate how ergometer design influences rowing stroke coordination patterns.
• To compare fixed and sliding stretcher ergometer designs.

Main Methods:

• 14 elite rowers participated in the study.
• Rowers were tested on three ergometer conditions: fixed stretcher Concept2c, sliding rail Concept2c, and sliding stretcher RowPerfect.
• Force data and a nine-segment inverse dynamics model were used to calculate power delivery.

Main Results:

• Peak knee joint power generation and absorption were significantly greater on the fixed stretcher ergometer.
• Total power delivery to the ergometer was delayed with fixed stretcher designs.
• Mechanical efficiency was reduced on the fixed stretcher ergometer due to increased lower limb power production.
• No differences in handle mechanical energy delivery were observed across ergometers.

Conclusions:

• Fixed foot stretchers increase inertial forces, leading to higher knee power output and altered coordination.
• Sliding stretcher ergometers may promote more efficient power transfer and a different coordination pattern.
• Ergometer design is a critical factor influencing biomechanics and performance in rowing.
