Intracycle velocity variation (IVV) in rowing is lower in sculling boats and longer boats, indicating better technical efficiency. This sensor-derived measure can monitor rowing technique across different boat classes.

Area of Science:

Sports Science
Biomechanics
Performance Analysis

Background:

Rowing performance is a function of boat velocity and technical efficiency.
These factors vary significantly across different boat classes and disciplines.
Quantifying intracycle velocity variation (IVV) offers insights into technical execution.

Purpose of the Study:

To quantify intracycle velocity variation (IVV) in competitive rowing across various boat classes.
To examine the relationship between IVV and biomechanical variables.
To determine if IVV is a useful indicator of technical efficiency in rowing.

Main Methods:

Collected data from 49 races involving 206 experienced rowers during national regattas.
Utilized GPS (15 Hz) and accelerometry (100 Hz) to record boat velocity and position.

Keywords:

GPS accelerometry biomechanics intracycle velocity variation on-water assessment rowing sensor-based monitoring technical efficiency

Classified boats by discipline (sweep vs. sculling) and length (short vs. long).

Main Results:

Sculling boats exhibited higher average velocity and lower IVV compared to sweep boats (p ≤ 0.05).
Longer boats achieved significantly higher velocities and demonstrated greater technical index and distance per cycle than shorter boats (p ≤ 0.05).
Strong correlations were found between velocity metrics, technical index, distance per cycle, and IVV, varying by boat class.

Conclusions:

Intracycle velocity variation (IVV) is influenced by boat class and crew characteristics.
IVV serves as a relevant sensor-derived indicator for monitoring technical efficiency in competitive rowing.
The findings highlight the importance of boat classification in analyzing rowing performance and technique.
