The force-time characteristics of the rowing stroke was examined in a coxless pair.
Sixteen highly trained rowers were evaluated in their usual training positions (stroke
or bow). Stroke rowers had higher stroke speed and stroke force in the first part
of the stroke than bow rowers. This finding was more prominent during competition
speed rowing than during endurance training. Higher blood lactate levels and lower
base excess were found at both speeds in stroke rowers. During and incremental ergometer
rowing test, lactate performance curves were shifted to the left in the stroke rowers.
Analysis of morphometric data in the left deltoid muscle demonstrated higher FT fiber
content and lower oxidative fiber capacity and fiber areas in the stroke rowers. The
results demonstrate adaptation to years of training in a specific boat position.
