Postexercise Hot-Water Immersion Does Not Further Enhance Heat Adaptation or Performance in Endurance Athletes Training in a Hot Environment

cardiovascular strain, 2 increased reliance on muscle glycogen, 3 and unpleasant thermal perceptions. 4 Minimizing heat-mediated impairments in performance is a priority for many athletes, and racewalking athletes are particularly affected as the inefficiency of racewalking leads to a greater rate of heat
Temporal Values and Plantar Pressures during Normal Walking and Racewalking in a Group of Racewalkers
M. Adoración Villarroya, José Antonio Casajús, and José María Pérez
Objectives:
To compare temporal and pressure values between racewalking and normal walking (freely selected speed) and evaluate the impact of racewalking on normal walking.
Design and Participants:
Temporal and plantar-pressure values were recorded (xPression system) during normal walking and racewalking in 8 high-level racewalkers. The Wilcoxon test was used for comparisons.
Measurements:
Duration of walking and racewalking cycle phases (seconds and percentage of the cycle), peak and average pressures under the hind foot and metatarsal heads, and pressure distribution (%) among metatarsal heads.
Results and Conclusions:
Normal walking: temporal parameters similar to those described in normal gait; peak pressures higher than those described in nonracewalkers with displacement toward lateral forefoot. Racewalking: shorter cycles (important decrease of midstance phase); higher peak pressures than during normal walking in the hind foot and 4th and 5th metatarsal heads; average pressures similar to normal walking in hind foot and lower in forefoot; pressure displacement toward lateral forefoot greater than in normal walking.
Adherence to a Ketogenic Low-Carbohydrate, High-Fat Diet Is Associated With Diminished Training Quality in Elite Racewalkers

Prof Louise Burke (Melbourne, Australia) credited the success she had with building a research program around the international racewalking community to regularly training with the athletes—luckily, she could run as fast as they walked.
