A. Personal Statement
I have been involved in human nutrition, metabolism, and physiology studies for more than 20 years. In particular, I have been involved in metabolic and outcome studies in aging populations for more than 16 yrs. These studies have addressed metabolic responses to both nutritional and pharmacological interventions. In addition, many studies have investigated these modalities on strength and functional outcome measures. Inherent in these studies was the development of expertise in the techniques to include calculations, validation and interpretation.
In my previous positions, I successfully administered many projects (e.g. staffing, research protections, budget), collaborated with other researchers, and produced several peer-reviewed publications from each project. These duties and experiences reinforced the importance of frequent communication among project members, as well as the development of research plans, timelines, and budget adherence. The current award is a logical transition and culmination of my prior work. I have a strong background in the metabolic measurements proposed, in particular, protein metabolism.

C. Contribution to Science
- Much of my early work centered on the use of anabolic agents in the restoration of skeletal muscle. In particular, this work elucidated the metabolic mechanisms that lead to muscle anabolism. While anabolic agents were routinely used (misused) in the athletic populations, their ability to restore muscle mass and function in clinical populations had not been previously investigated. One of the first investigations centered on the administration of testosterone in older, hypongondal populations. We found that testosterone, and its derivatives, promoted muscle anabolism similarly in both young and older subjects by increasing the rate of muscle protein synthesis. Based upon these initial studies, we examined testosterone’s effects after long-term supplementation in the elderly. Our results demonstrated that a longer supplemental period in hypogonadal men was both safe and efficacious in promoting mass and functional improvements. Further, the study revealed that the responsible anabolic mechanism in skeletal muscle was different with short term versus longer-term administration. These studies provided the metabolic rationale for follow-on clinical trials investigating the safety and efficacy of longitudinal testosterone administration in hypongonadal men.

- With this understanding of testosterone’s anabolic effects, investigations were extended to clinical populations of severe trauma. Testosterone, and its derivatives, was utilized in severely burned patients during their ICU stay. The studies demonstrated that the anabolic mechanism differed in the skeletal muscle of burn patients, and further, between adult and pediatric burn patients. The primary effect in adult burn patients was a decrease in skeletal muscle protein breakdown and a concomitant increase in protein synthetic efficiency. In pediatric burn patients, the stimulation of muscle protein synthesis was responsible for improved anabolism. The studies were extrapolated to long-term usage after discharge and demonstrated the benefits in recovery of pediatric burn injury. As a result of these efforts, the use of testosterone in the recovery from severe burns is now an important clinical paradigm.

- Though the studies on testosterone administration were beneficial, the hormonal supplementation was primarily restricted to males. Other anabolic agents such as insulin, IGF-1, and growth hormone were subsequently utilized in both pediatric and adult burn patients. While there are some differences in the affected anabolic mechanism between pediatric and adult patients, each anabolic agent was successful in ameliorating the loss of lean body/muscle mass. Again, these studies provided the foundation for routine treatment of severe injury (burn) patients with anabolic agents during their ICU stay.

- Our laboratory conducted the seminal work in the response of muscle and whole-body protein metabolism to prolonged inactivity. Initially conducted as ground-based analogues for space flight, our work indicated that the primary reason for the loss of muscle with inactivity was the reduction in muscle and whole-body protein synthesis. We later extrapolated this work to a more clinically relevant population and found that the mechanistic cause for the loss of body protein was consistent in older subjects. To more closely model actual clinical inactivity, subsequent efforts investigated the combined effects of inactivity and stress

- Recent work has focused on the effects of increased amino acid and/or protein intake on skeletal muscle and function in older populations. In addition to the benefits of increased amino acid intake during inactivity (see number 4 above), we have demonstrated that increasing protein/amino acid intake in older populations improves protein kinetics. The improvement in protein kinetics translates to improved functional and lean mass in older subjects. Further, we have demonstrated that increased essential amino acid intake improves muscle function during recovery from joint replacement.
