摘要

This study aimed to investigate the physiological and self-reported performance changes during a 1‑h effort test and their influence on the subsequent graded exercise test (GXT) to exhaustion, comparing two advanced footwear technology (AFT) shoes in trained male runners. In a randomized-counterbalanced study design, 12 trained male runners (World Athletics [WA] score: 820.8 ± 107.3 points) performed a GXT until first ventilatory threshold (VT1) speed determination, followed by a 1‑h effort at +10% VT1 speed, and finally a GXT until exhaustion across two sessions separated by 7–10 days with different AFT shoes (Cloudboom Strike [CS] and Cloudboom Echo 3 [CE]). Metabolic and self-reported parameters were monitored throughout. No shoe*time interaction effect was found during the 1‑h effort test. However, participants exhibited an increase in heart rate (p < 0.001) and in the rate of perceived exertion (RPE; p < 0.001) alongside a reduction in respiratory exchange ratio (RER; p < 0.01) and in carbon dioxide production (p < 0.05), with a shift in substrate utilization from carbohydrate oxidation to fat oxidation (p < 0.05), irrespective of the shoe model. During the GXT, participants in the CS condition achieved higher peak speed (p < 0.05) and higher VT2 speed (p < 0.05) compared to the CE group, as well as lower RER at VT2 (p < 0.05). In conclusion, 1‑h effort at +10% VT1 speed increases cardiovascular strain and RPE, with enhanced fat oxidation, without any influence of the shoes used. During the GXT test, participants had higher peak velocity and higher VT2 velocity when using CS than when using CE.
