The study is oriented toward an integrated comprehension of the physiological, biomechanical, and psychoemotional determinants of a dancer’s professional transformation during the transition from the domain of competitive ballroom dancing to the entertainment-show format on ocean cruise liners. The transition is analyzed on the basis of the author’s clinical and training case material and is interpreted through the figurative continuum from sprint to marathon, in which competitive ballroom dancing, grounded predominantly in submaximal anaerobic power and short-term interval loads, is contrasted with the functional profile of onboard work that presupposes the predominance of prolonged aerobic endurance, stable tolerance of monotonous repetitive actions, and specific sensorimotor adaptation to continuously changing support characteristics. Within the study, the neurophysiological mechanisms of neuroplasticity underlying the formation of the sea legs phenomenon are examined in detail; the structure and frequency of injuries are analyzed with an emphasis on the redistribution of mechanical loads from the distal segments of the lower limb (the ankle joint) to proximal links, namely the knee joint and the lumbar spine; and the phenomenon of a nutritional paradox is described under conditions of practically unlimited access to buffet-style nutrition onboard. On the basis of integrating data from sports medicine, maritime physiology, and dietetics, personalized protocols for the periodization of the training process and for nutritional support strategies have been developed, aimed at optimizing the dancer’s functional performance capacity and reducing the probability of developing relative energy deficiency in sport syndrome (RED-S) under the conditions of a prolonged contract cycle of 6–9 months.
