Physiological Responses to Snowshoeing with Rotating Toe Cord Systems versus Fixed Toe Cord Designs in Men at Self-Selected Intensity

Article excerpt

Lance Dalleck and Dale DeVoe, Colorado State University

The purpose of this study was to measure potential differences in the physiological responses of active men, while snowshoeing with two separate toe cord designs, rotating toe cord system versus fixed toe cord design, in deep, powdered snow conditions (depression depth = 20.3 + 8.1 cm). Eight men (age = 24.9 [plus or minus] 2.4 years, ht = 181.5 [plus or minus] 7.8 cm, wt = 76.3 [plus or minus] 8.6 kg) were recruited to snowshoe at a self-selected intensity for two, 1600m trials in randomly assigned snowshoes, rotating toe cord system and a fixed toe cord design. Heart rate (HR) was measured utilizing a Polar Vantage XL monitor; oxygen consumption ([VO.sub.2]), percent-expired carbon dioxide (%[CO.sub.2]), percentage of expired oxygen (%[O.sub.2]), and ventilation (VE) were measured using an Aerosport KB1-C portable metabolic analysis system. …
