Effects of a Transoceanic Rowing Challenge on Cardiorespiratory Function and Muscle Fitness
Int J Sports Med DOI: 10.1055/a-2205-1849Ultra-endurance sports and exercise events are becoming increasingly popular for
older age groups. We aimed to evaluate changes in cardiac function and physical
fitness in males aged 50–60 years who completed a 50-day transoceanic rowing
challenge. This case account of four self-selected males included electro- and
echo-cardiography (ECG, echo), cardiorespiratory and muscular fitness measures
recorded nine months prior to and three weeks after a transatlantic team-rowing
challenge. No clinically significant changes to myocardial function were found
over the course of the study. The training and race created expected functional
changes to left ventricular and atrial function; the former associated with
training, the latter likely due to dehydration, both resolving towards baseline
within three weeks post-event. From race-start to finish all rowers lost
8.4–15.6 kg of body mass. Absolute cardiorespiratory power and muscular strength
were lower three weeks post-race compared to pre-race, but cardiorespiratory
exercise economy improved in this same period. A structured program of
moderate-vigorous aerobic endurance and muscular training for>6 months,
followed by 50-days of transoceanic rowing in older males proved not to cause
any observable acute or potential long-term ris...
