Investigation Of Acute Response To Carbohydrate In Subsequent Resistance Training, Damon Mccune

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resistance training has been shown to have several positive benefits to health including increasing muscle size and strength, reducing risk of sarcopenia with aging, and is associated with reduced risk of mortality. A cornerstone in accomplishing these goals is to progressively overload the muscle by increasing training volume to promote muscle protein synthesis following training stimulation. Total training volume has been demonstrated in the literature to be a prime determinant of muscle hypertrophy and overall training performance. Carbohydrate (CHO) manipulation has been observed as a potential ergogenic aid when training demands are high. Current research investigating nutrition related to exercise …

Prioritization Of Variants For Investigation Of Genotype-Directed Nutrition In Human Superpopulations, Pascal D. Nilsson, Jacklyn M. Newsome, Henry M. Santos, Martin R. Schiller

Life Sciences Faculty Research

Dietary guidelines recommended by key health agencies are generally designed for a global population. However, ethnicity affects human disease and environment-gene interactions, including nutrient intake. Historically, isolated human populations with different genetic backgrounds have adapted to distinct environments with varying food sources. Ethnicity is relevant to the interaction of food intake with genes and disease susceptibility; yet major health agencies generally do not recommend food and nutrients codified by population genotypes and their frequencies. In this paper, we have consolidated published nutrigenetic variants and examine their frequencies in human superpopulations to prioritize these variants for future investigation of population-specific genotype-directed …
