Seven days of mixed‐method heat acclimation improved markers of cardiovascular and fluid‐regulatory strain during exercise‐heat stress

Experimental Physiology, EarlyView.
Abstract A mixed‐method heat acclimation (HA) protocol may optimise performance by supporting the training taper while promoting thermal adaptation; however, the impact on cardiovascular and fluid‐regulatory adjustments to protect health is unknown. Therefore, we examined the effects of a mixed‐method heat protocol on physiological responses, including

Fine-root production in two secondary forest sites with distinct ages in Eastern Amazon Produção de raízes finas em dois sítios de floresta secundária com diferentes idades na Amazônia Oriental

Acta Amazonica, 2012
The objective of this work was to assess the fine-root (≤ 2 mm diameter) production dynamics of two forest regrowths at different ages. Fine-root production was monitored by the ingrowth core method in one 18-year-old site (2 ha) and one 10-year ...

Passive thigh heating improves peak force production in younger adults and early isokinetic force production in younger and older adults

Experimental Physiology, EarlyView.
Abstract Older adults often suffer from reduced physical capability relative to young adults, in part due to impaired muscle function. This study investigated the ergogenic effects of passive thigh heating on knee extensor torque production in healthy older versus younger adults.

Tropical Dry Forest Succession and the Contribution of Lianas to Wood Area Index (WAI) [PDF]

, 2009
The transmission and interception of light through the canopy is an important indicator of forest productivity in tropical forest ecosystems, and the amount of light that eventually reaches the forest floor is influenced by its interactions with leaves ...

Vascular, inflammatory and perceptual responses to hot water immersion: Impacts of water depth and temperature in young healthy adults

Experimental Physiology, EarlyView.
Abstract Repeated hot water immersion can improve cardiovascular health; however, the respective effects of distinct immersion protocols remain unclear. Twenty‐two healthy adults completed three 30‐min hot water immersion bouts of different water temperatures and immersion depths (40°C shoulder‐deep immersion, 40‐Shoulder; 42°C waist‐deep immersion, 42‐

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Acute metabolic responses to high‐intensity interval training in men with overweight or obesity: Does the exercise modality matter?

Experimental Physiology, EarlyView.
Abstract This study investigated the acute effects of two isoenergetic high‐intensity interval exercise (HIIE) sessions, running (HIIE‐RUN) and cycling (HIIE‐BIKE), on post‐exercise oxygen consumption (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$), carbon dioxide production (V̇CO2${\dot V_{{\mathrm{C}}{{\mathrm{O}}_2}}}$), substrate oxidation and 24‐h energy ...
