Timing of return from altitude training for optimal sea level performance.
While a number of published studies exist to guide endurance athletes with the best practices regarding implementation of altitude training, a key unanswered question concerns the proper timing of return to sea level prior to major competitions. Evidence reviewed here suggests that, altogether, the deacclimatization responses of hematological, ventilatory, and biomechanical factors with return ...
متن کاملPhysiological implications of altitude training for endurance performance at sea level: a review.
Acclimatisation to environmental hypoxia initiates a series of metabolic and musculocardio-respiratory adaptations that influence oxygen transport and utilisation, or better still, being born and raised at altitude, is necessary to achieve optimal physical performance at altitude, scientific evidence to support the potentiating effects after return to sea level is at present equivocal. Despite ...
متن کاملDefining the "dose" of altitude training: how high to live for optimal sea level performance enhancement.
Chronic living at altitudes of ∼2,500 m causes consistent hematological acclimatization in most, but not all, groups of athletes; however, responses of erythropoietin (EPO) and red cell mass to a given altitude show substantial individual variability. We hypothesized that athletes living at higher altitudes would experience greater improvements in sea level performance, secondary to greater hem...
متن کاملThe utility of immature reticulocyte fraction as an indicator of erythropoietic response to altitude training in elite cyclists.
Altitude training is sometimes employed by elite endurance athletes to improve their sea level performance. This improvement results from the increased red cell mass consequent upon the boost in erythropoietin (EPO) level that occurs as a response to the relatively hypoxic environment at high altitudes. We measured serum EPO levels together with various red cell and reticulocyte parameters incl...
متن کاملChapter 27 Altitude and hypoxic training in swimming
Altitude/hypoxic training is nowadays a common practice among swimmers although its benefits are still controversial in scientific literature. Traditional altitude training (“live high-train high”) is still the most frequently used method in swimming, even though from a physiological perspective the “live high-train low” strategy appears to be a more promising alternative. While acute hypoxia d...
