Comparing in-phase to antiphase crew rowing: a first step from the lab to the water

Area of Science:

• Sports Science
• Biomechanics
• Hydrodynamics

Background:

• Rowing crews synchronize strokes for peak performance.
• Antiphase coordination (alternating strokes) theoretically reduces boat velocity fluctuations and hydrodynamic drag, potentially improving race times.

Purpose of the Study:

• To assess the feasibility of antiphase rowing on water.
• To determine if antiphase rowing reduces boat velocity fluctuations.
• To investigate the impact of antiphase rowing on race times.

Main Methods:

• Nine pairs of experienced rowers completed 1,000m trials in both in-phase and antiphase patterns.
• Trials were conducted at 20 and 30 strokes per minute.
• Crew coordination, boat kinematics, and race times were analyzed.

Main Results:

• Most crews successfully maintained a stable antiphase rowing pattern during their first attempts.
• Antiphase rowing significantly reduced boat velocity fluctuations, particularly at higher stroke rates.
• Faster race times were not observed in these initial trials.

Conclusions:

• Antiphase rowing is a feasible technique for experienced crews on water.
• Reduced velocity fluctuations with antiphase rowing do not automatically translate to faster race times.
• Further research is needed to optimize antiphase rowing for potential race time improvements through practice and equipment adjustments.
