Exercise Cerebral Blood Flow Hemodynamics Differ In Hot Dry And Humid Conditions, Julianna J. Kilpatrick, Paolo Miguel Salvador, Kyleigh Allie, Eric Rivas
International Journal of Exercise Science: Conference Proceedings
Passive and exercise-heat stress have been reported to cause reductions in cerebral blood flow (CBF); however, it is unknown if CBF velocity is different under hot dry and humid conditions. PURPOSE: This project tested the hypothesis that upright rest and exercise-heat stress in hot dry and humid conditions result in similar CBF reductions. METHODS: Seven healthy active (7 day activity: 9887±3564 steps/day; VO2max: 52±10 mL/kg/min) subjects (5M/2F, 24±9y, 171±6cm, 68±7kg) completed a 30 min baseline rest followed by 60 min of exercise at a rate of perceived exertion (RPE) of 12 (between light and somewhat hard) on a …
Low Intensity Exercise Has Greater Acute Vascular Benefits For Reducing Arterial Stiffness In Hot Compared To Neutral Conditions, Kyleigh N. Allie, Julianna Kilpatrick, Paolo Salvador, Eric Rivas
Low Intensity Exercise Has Greater Acute Vascular Benefits For Reducing Arterial Stiffness In Hot Compared To Neutral Conditions, Kyleigh N. Allie, Julianna Kilpatrick, Paolo Salvador, Eric Rivas
International Journal of Exercise Science: Conference Proceedings
Both exercise and passive heating cause acute reductions in blood pressure. It is unknown if exercise-heat stress causes likewise reductions or greater when combined. PURPOSE: This project tested the hypothesis that the resting and exercise-heat stress cause hypotension and improvements in arterial stiffness. METHODS: Seven healthy active (7 day activity: 9887±3564 steps/day; VO2max: 52±10 mL/kg/min ) subjects (5M/2F, 24±9y, 171±6cm, 68±7kg) completed a 30 min baseline rest followed by 60 min at an exercise intensity of their choice that represented their perceived exertion (RPE) of 12 (between light and somewhat hard) on a 20-point rating scale while being blinded to …
Skin Temperature And High Dew Point In Hot Environments Affects Self-Paced Exercise, Paolo Miguel Salvador, Julianna Kilpatrick, Kyleigh Allie, Eric Rivas
Skin Temperature And High Dew Point In Hot Environments Affects Self-Paced Exercise, Paolo Miguel Salvador, Julianna Kilpatrick, Kyleigh Allie, Eric Rivas
International Journal of Exercise Science: Conference Proceedings
Dew point (dp) is the absolute measure of water vapor and directly affects comfort whereas 5-10℃ feels dry; 10-15℃ feels comfortable and 20-24℃ feels uncomfortable. PURPOSE: This project tested the hypothesis that exercise in hot ambient conditions with a high dp (>20℃) would affect the selection of self-paced exercise compared to neutral dry conditions (dp). METHODS: Six healthy active (7 day activity: 9826±3900 steps/day; VO2max: 52±10 mL/kg/min ) subjects (4M/2F, 25±9y, 171±6cm, 69±7kg) completed a 30 min baseline rest then 60 min of exercise intensity they chose that represents their perceived exertion of 12 …
