Wearable power meters are increasingly popular among runners with Coros and Stryd offering running power as a real-time, trackable of a metric. PURPOSE: This study compared running power (RP) to physiological measures, heart rate (HR) and oxygen consumption (VO2), across high and low intensity running intervals. METHODS: Thirteen adult participants (n = 6 male; height = 174.9 ± 6.9 cm; mass = 72.5 ± 12.0 kg) were equipped with a Stryd 27 RP meter, a Polar H10 HR monitor, and a Cosmed K5 portable metabolic unit. Participants’ self-selected RP was obtained during a 10-min run on …
Bicycle Handlebar Width Does Not Affect Spirometry, Ventilation, Or Gas Exchange, Matthew J. Fahey, Daniel T. Cannon
Bicycle Handlebar Width Does Not Affect Spirometry, Ventilation, Or Gas Exchange, Matthew J. Fahey, Daniel T. Cannon
International Journal of Exercise Science: Conference Proceedings
Bicycle fit may affect comfort, aerodynamics, efficiency, ventilation, and power generation. Handlebars determine how the rider interacts with the bicycle. A wide range of handlebar widths are commercially available, but it is unclear if the resultant position affects lung function, ventilation, gas exchange, or efficiency. PURPOSE We aimed to measure the effects of handlebar widths on ventilation, gas exchange, spirometry, and comfort during moderate constant power exercise. METHODS Twenty-four recreationally active adults completed the study (32 ± 5 yrs., 175 ± 9 cm, 74 ± 12 kg, 8 women, 16 men). Participants completed three moderate constant power bouts of exercise …
Social Jetlag Inhibits Exercise-Induced Adaptations In The Heart And Alters Markers Of Mitochondrial Dynamics, Graham R. Mcginnis, Michael B. Dial, Elias M. Malek, Greco Neblina, Austin Cooper, Nikoleta Vasileva, Tanner Erwin
Social Jetlag Inhibits Exercise-Induced Adaptations In The Heart And Alters Markers Of Mitochondrial Dynamics, Graham R. Mcginnis, Michael B. Dial, Elias M. Malek, Greco Neblina, Austin Cooper, Nikoleta Vasileva, Tanner Erwin

Social jetlag (SJL), or the shifting of behavior and sleep times between weekdays and weekends, is a pervasive form of circadian rhythm disruption that affects nearly 70% of the population to some extent. The magnitude of SJL can be determined by the difference in the mid-sleep phase between weekends and weekdays. Higher levels of SJL have been associated with lower levels of cardiorespiratory fitness, and increased incidence of cardiometabolic disease, which may be due, in part, to mitochondrial dysfunction. However, no studies to date have evaluated the effects of long term SJL on cardiac mitochondrial dynamics. PURPOSE: To determine …
Can We Calculate Mean Arterial Pressure In Humans?, Matthew M. Howrey, Tiffany L. Brazile, Bryce N. Balmain, Andrew R. Tomlinson, James P. Macnamara, Tony G. Babb, Benjamin D. Levine, Satyam Sarma, Christopher M. Hearon Jr, Denis J. Wakeham
Can We Calculate Mean Arterial Pressure In Humans?, Matthew M. Howrey, Tiffany L. Brazile, Bryce N. Balmain, Andrew R. Tomlinson, James P. Macnamara, Tony G. Babb, Benjamin D. Levine, Satyam Sarma, Christopher M. Hearon Jr, Denis J. Wakeham

Mean arterial pressure (MAP) is either measured with an oscillometric cuff and then systolic (SBP) and diastolic (DBP) blood pressures are estimated from an unknown algorithm; or SBP and DBP are measured via auscultation and MAP calculated using measures of systolic pressure (SBP), diastolic pressure (DBP), and a form-factor (FF; equation: [(SBP-DBP)*FF]+DBP). The typical FF used is 0.33 though others (0.4) have been proposed. Recent work indicates that estimation of aortic MAP via a FF leads to inaccurate values and should therefore be interpreted with caution, whether this is the case for local MAP is unknown. While the implications for …
The Effects Of Resistance Deception On Upper Body Muscular Strength, Muscular Endurance, And Perceived Exertion, Ashley Mcmasters
The Effects Of Resistance Deception On Upper Body Muscular Strength, Muscular Endurance, And Perceived Exertion, Ashley Mcmasters
International Journal of Exercise Science: Conference Proceedings
Resistance deception during training is lightly researched and is seen as a modification that can potentially act on central control during exercise. Studies that have observed the effects of deception while training has yielded mixed results and the effects of deception on strength, muscular endurance, and perceived exertion are still unclear. PURPOSE: The purpose of this study was to determine the effects of resistance deception on upper-body maximal muscular strength, muscular endurance, and perceived exertion in a strength-trained population. METHODS: Eight males (n = 5) and females (n = 3) between the ages of 18 and 26 that had at …
Thirst Sensation Does Not Effect Reaction Time But Decreses Mood In Men, Alan Ky, Hui-Ying Luk, Jarrod Blinch, Yasuki Sekiguchi
Thirst Sensation Does Not Effect Reaction Time But Decreses Mood In Men, Alan Ky, Hui-Ying Luk, Jarrod Blinch, Yasuki Sekiguchi
International Journal of Exercise Science: Conference Proceedings
Exercise in hot environments results in dehydration accompanied by thirst sensation, a vital signal for fluid homeostasis. While cognitive performance and mood have been studied with exercise in hot environments and in dehydration states, no studies have investigated the effect of inducing thirst on cognitive performance and mood. PURPOSE: To investigate the effect of inducing thirst on cognitive performance and mood. METHODS: Twelve recreationally active men (mean±SE age: 29±3.6 years; body mass: 74.7±2.3 kg; height, 179.4±2.0 cm; maximal oxygen consumption [VO2max]: 49.8±1.9 ml·kg−1·min−1) performed 90 mins of cycling at 55% VO2max …

Exercise is beneficial to improve metabolic diseases such as obesity and type 2 diabetes. Physical activity results in an increase in energy expenditure (EE) and oxygen consumption due to increased energy demand. Neuromuscular electrical stimulation (NMES) is an alternative strategy to induce muscle contraction. Our previous work have shown that NMES induced muscle contraction can improve metabolic health in an overweight and obese population. However, it is not known whether NMES induced muscle contraction leads to greater energy expenditure. PUPROSE: To determine the effect of NMES induced muscle contraction on energy expenditure and oxygen consumption. METHODS: Eighteen sedentary overweight/obese men …
