Although inorganic nitrate (NO 3 − ) supplementation has increased in popularity as a means of improving exercise performance, data females at different phases the menstrual cycle are lacking despite known interactions estrogen with NO. This study revealed neither NO nor influenced economy or vascular health healthy young naturally menstruating females, while significantly worsened endurance capacity (10%) independent phase.
Dietary nitrate (NO
Critical power (CP) delineates the heavy and severe exercise intensity domains, sustained work rates above CP result in an inexorable progression of oxygen uptake to a maximal value and, subsequently, limit tolerance. The finite capacity CP, W', is defined by curvature constant power-duration relationship. Heavy or hot environment generates additional challenges related rise body core temperature (Tc) that may impact W'. purpose this study was determine effect elevated Tc on W' were...
Recent data have suggested that inorganic nitrate ([Formula: see text]) supplementation may benefit males, however, females experience worsened endurance capacity independent of menstrual cycle phase. This study revealed neither [Formula: text] nor the follicular phase influenced maximal isometric voluntary contraction or in healthy, young, naturally menstruating females, whereas significantly estimated peak power (Pmax) and velocity (Vmax)
Inorganic nitrate (NO
Inorganic nitrate (NO3-) can be reduced to nitrite via the entero-salivary pathway and then nitric oxide in oxygen states such as exercise. Oral NO3- supplementation improves tissue oxygenation during exercise, however, sex-dependent responses are lacking. PURPOSE: To examine effect of on moderate- (MOD) severe-intensity (SEV) exercise young adults. METHODS: Cycle ergometry was performed determine gas exchange threshold (GET) VO2peak. In a randomized, double-blind crossover study, 12 females...
INTRODUCTION: Aging is associated with a decrease in cognitive function (CF), perhaps part, related to decreased cerebral blood flow (CBF). CBF diminished at rest and response moderate intensity exercise older adults. Strategies increase may be useful restoring CF these individuals. PURPOSE: To examine the effects of calorically matched acute bouts continuous (MIC) versus high interval training (HIIT) on middle artery velocity (MCAv) METHODS: Seven healthy adults (6 males, 1 females) >65...
Critical Power (CP) separates the heavy and severe exercise domains, work above CP (defined as W′) results in an inexorable progression to maximal oxygen uptake rise blood lactate concentration fatigue. The thermoregulatory demands accompanying a body core temperature (T c ) compounded with cardiovascular challenges presented by hot environment may impact W′. To date, no study has explored effects of elevated T environmental on purpose this is determine effect high was estimated end test...
PURPOSE: Inorganic nitrate (NO3-) supplementation increases nitric oxide (NO) bioavailability and may improve exercise performance. In females, estrogen endogenous eNOS production of NO, but fluctuates throughout the menstrual cycle (MC). It is unknown if different phases MC or exogenous NO3- impact maximal voluntary isometric contraction (MVIC), isokinetic torque, power in apparently healthy young females. The purpose this study was to examine potential differences MVIC, across early (EF)...
Nitric Oxide (NO) plays a pivotal role in muscle contractile function. Inorganic nitrate (NO3-) supplementation has been demonstrated to increase NO bioavailability and potentially act as an ergogenic aid subjects with NOS dysfunction. Exercise responses NO3- healthy young adults are conflicting few studies have examined sex differences. PURPOSE: To determine the effects of on skeletal force development endurance during knee extension males females. METHODS: Seven females (age 24.0 ± 3.6y)...
