Exercise Intolerance in Young Physically Active Smokers Compared to Non‐Smokers During Sinusoidal Cycling

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 9, September 2026.
ABSTRACT The impact of cigarette smoking on the cardiorespiratory response to exhaustive exercise remains unclear. This study investigated the smoking effect on exercise tolerance by analyzing the cardiorespiratory and metabolic variables during an exhausting sinusoidal exercise in young physically active smokers (SM) without known cardiovascular and ...

Transboundary Policy Perspectives on Migratory Bird Stopover Sites Conservation: A Case Study of Yancheng (China) and Geelong (Australia) 迁徙鸟类停歇地保护的跨境政策视角 —— 以中国盐城与澳大利亚吉朗为例

open access: yesWildlife Letters, Volume 4, Issue 3, Page 149-159, September 2026.
Migratory shorebirds traveling the East Asian–Australasian Flyway face systemic policy fragmentation and habitat disconnection between China (coordination challenges and renewable energy conflicts) and Australia (federal governance fragmentation). This study proposes a transboundary conservation framework to fill this gap.
