Fluid Intake And Sweat Rate During Hot Yoga Participation, Stephanie Campbell, Robert C. Pritchett, Katie Cederburg, Tim Burnham, Kelly C. Pritchett
International Journal of Exercise Science
International Journal of Exercise Science 10(5): 721-733, 2017. Hot yoga participants are at risk for dehydration due to the nature of the environment they exercise in. Therefore, the purpose of this study was to investigate the pre-exercise hydration status, fluid balance, perception of sweat loss, and sweat sodium loss in 21 male and female hot yoga participants (mean age ± SD, 33.0 ± 10.5 yr; mass, 70.7 ± 11.0 kg). Data was recorded pre and post a one- hour hot yoga class (38.7 ± 2.6 °C, 36 ± 13% relative humidity). Pre-exercise urine specific gravity (USG), hydration status, body mass …
Irisin And Fibronectin Type Iii Domain-Containing 5 Responses To Exercise In Different Environmental Conditions, Matthew Bubak, Matthew W.S. Heesch, Robert J. Shute, Nicholas E. Dinan, Terence L. Laursen, D. Taylor La Salle, Dustin R. Slivka
Irisin And Fibronectin Type Iii Domain-Containing 5 Responses To Exercise In Different Environmental Conditions, Matthew Bubak, Matthew W.S. Heesch, Robert J. Shute, Nicholas E. Dinan, Terence L. Laursen, D. Taylor La Salle, Dustin R. Slivka
International Journal of Exercise Science
International Journal of Exercise Science 10(5): 666-680, 2017. Fibronectin type III domain-containing 5 (FNDC5) is a skeletal muscle membrane-bound precursor to the myokine irisin. Irisin is involved in stimulating adipose tissue to become more metabolically active in order to produce heat. The purpose of this study was to determine the effects of exercise in a hot (33 °C), cold (7 °C), and room temperature (RT, 20 °C) environment on the skeletal muscle gene expression of FNDC5 and the plasma concentrations of irisin. Twelve recreationally trained males completed three separate, 1 h cycling bouts at 60% of Wmax in a …
The Effect Of Psychomotor Performance, Cerebral And Arterial Blood Saturation Between African-American And Caucasian Males Before, During And After Normobaric Hypoxic Exercise, Matthew R. Feeback, Yongsuk Seo, Matthew Dancy, Ellen L. Glickman
The Effect Of Psychomotor Performance, Cerebral And Arterial Blood Saturation Between African-American And Caucasian Males Before, During And After Normobaric Hypoxic Exercise, Matthew R. Feeback, Yongsuk Seo, Matthew Dancy, Ellen L. Glickman
International Journal of Exercise Science
International Journal of Exercise Science 10(5): 655-665, 2017. To further elucidate physiological and cognitive performance differences between African-American (AA) and Caucasian individuals (CAU) before, during or after hypoxic and normoxic exercise. Twelve college aged (18-25) apparently healthy African-American (six volunteers) and Caucasian (six subjects) males took part in two trials consisting of normobaric normoxia and normobaric hypoxia (12% oxygen). Each subject cycled at 50% of their altitude adjusted VO2max (-26% of normoxia VO2max) for one hour after a two-hour baseline. Subjects were monitored for cerebral and arterial O2 saturation, as well as the Trail Making Test …
Non-Invasive Measures Of Core Temperature Versus Ingestible Thermistor During Exercise In The Heat, Donovan L. Fogt, Andrea L. Henning, Adam Venable, Brian K. Mcfarlin
Non-Invasive Measures Of Core Temperature Versus Ingestible Thermistor During Exercise In The Heat, Donovan L. Fogt, Andrea L. Henning, Adam Venable, Brian K. Mcfarlin
International Journal of Exercise Science
International Journal of Exercise Science 10(2): 225-233, 2017 The accuracy of core temperature (Tc) thermometry from temporal, tympanic, and oral thermometry devices has been variable during exercise in a hot, humid environment. The purpose of the present study was to cross-validate temporal, two tympanic devices, and oral devices compared to an ingestible thermistor during exercise in a hot, humid environment. Fourteen young, active adults (6 women) completed a graded exercise test until voluntary exhaustion in an environmental chamber (35.5 ± 0.6 °C, 53.9 ± 5.8 % RH). There was no statistical difference in mean temperature between tympanic device …
Effects Of Simulated Altitude On Maximal Oxygen Uptake And Inspiratory Fitness, Nicole Biggs, Benjamin England, Nicole Turcotte, Melissa R. Cook, Alyne L. Williams
Effects Of Simulated Altitude On Maximal Oxygen Uptake And Inspiratory Fitness, Nicole Biggs, Benjamin England, Nicole Turcotte, Melissa R. Cook, Alyne L. Williams
International Journal of Exercise Science
International Journal of Exercise Science 10(1): 128-136, 2017 Aerobic exercise at altitude has shown an increase in maximal oxygen uptake. Similar effects have been replicated by way of simulated altitude training, which have influenced various advances in the field of exercise science. Elevation Training Masks© (ETM) claim to stimulate cardiorespiratory fitness improvements similar to training at altitude, however, there is little research to support this claim. The purpose of this study was to research the effect that a hypoxia-inducing mask would have on cardiorespiratory fitness and pulmonary function through the use of a high intensity interval training (HIIT) running program. …
