The human body before and after a round the world race are two different things.

A long-distance transoceanic race causes changes in the human body and its metabolism. Understanding these changes is a great tool for developing performance and optimising the health and wellbeing of the sailors.

Physical wear in a round the world regatta can be observed using a number of biochemical markers from sailors. Belén Gualis, Juan Ybarra, Mónica Isart, Eva Montoya, from the Centro Médico Teknon in Barcelona, carried out a study on the physical effects on the organism caused by stress in 10 Barcelona World Race 2014/15 sailors.

All of the participants had been immersed in the extreme climate conditions faced by ocean sailors, with no stopovers, during an extended period of approximately three months, with changes in circadian cycles and the impact of a racing diet, all taking place in a competitive environment, 24 hours a day, seven days a week.

During the study, a series of anthropometric parameters were measured, with analysis focussing on biological metabolic markers and hormones. This data was collected before the race start and immediately upon finishing the race.
