Why was this study done? The timing of fluid replacement is of great interest to competitive athletes. This study was designed to understand how starting fluid replacement immediately upon exercising compared to starting fluid later and how these strategies would affect time to fatigue in competitive cyclists. What did the study find? A fluid replacement…
Why was this study done? Competitive cyclists expend a large amount of energy and replacing glycogen (short-term storage of glucose) is important to maintain high performance throughout long exercise bouts. It has been estimated that consuming between 525 to 648 grams of carbohydrate in the 24 hours following exercise is ideal for glycogen replacement. This…
Why was this study done? Astronauts commonly experience dehydration during long flights. It is important to understand the role of rehydration formulas and their ability to prevent dehydration (maintenance of plasma volume). This study was designed to better understand the role of differing concentrations of rehydration formulas on dehydrated subjects. What did the study find?…
Why was this study done? Athletes who engage in long exercise bouts have an interest in sparing muscle glycogen (short-term storage of glucose) because of the dramatic reduction of energy output and fatigue that occurs when glycogen is depleted (known colloquially as “hitting the wall”). This study was designed to help understand how varying exercise…
Why was this study done? The effects of differing meals (mostly protein, mostly carbohydrate, or a combination of protein and carbohydrate) following exercise on professional athletes are well known, but how these meals effect less trained people are not as well known. This study investigated the effects of differing post-exercise meals on blood parameters in…
Why was this study done? The role of hormones (insulin, testosterone, growth hormone) in muscle building is fairly well established. What is less understood is the role of macronutrients (protein, carbohydrate, fats) and their impact on those hormones. This study was designed to help understand the importance of post-exercise supplementation for anabolic hormone production. Participants…
Why was this study done? Astronauts and athletes can experience a drop immune system function due to various stressors experienced during long flights. Dehydration is a common stressor to both athletes and astronauts. This study was designed to understand the role of proper hydration and its relationship to the immune system. What did the study…
Why was this study done? It has long been thought that thirst and dehydration sensations are regulated by plasma osmolality (concentration of electrolytes). This study was designed to help understand the mechanisms underlying thirst. What did the study find? That the act of drinking produces a neural response (through a hormone called norepinephrine) that alerts…
Why was this study done? Caloric restriction is well-known to reduce metabolic rate because of a loss of lean body mass. Discovering ways to reduce caloric intake while maintaining lean body mass is of utmost importance to persons who wish to lose and maintain a healthy weight. This study was designed to understand the role…
Why was this study done? Dehydration is thought to play an important role in the management of fatigue for athletes. This study was designed to help understand the role of rehydration formulas, their relationship to plasma volume, and fatigue. What did the study find? The formula (AA) provided the larger pre-exercise volume, greater acid-buffering, and…
