KIN 369 Exam Questions with Complete Correct Answers | Grade A+

what factors impact creatine's ergogenic effect? Ans: -age -type of exercise -timing of ingestion -combined with other foods what mechanisms are involved with increased muscle mass? Ans: - increased high energy phosphate pool -PCr resynthesis post-exercise -cellular hydration status -satellite-cell activity -myofibrillar protein kinetics -IGFs production -training intensity -decreased inflammation 2 what happens when you maintain 2g/day of creatine rather than stopping altogether Ans: allows you to stay at a high level after a long period of time vs. dropping after day 7 of stopping effect of creatine on IGFs Ans: -much more IGFs with creatine -increase 78% what do IGFs do? Ans: -most IGF-1 production occurs in liver in response to hGH -acts as an endocrine hormone for tissue-specific growth and differentiation -controls local tissue repair and remodelling -bring in more glucose for exercise IGF + creatine Ans: -high energy phosphate metabolism (PCr and total Cr increase) -training intensity -essential AA production important to maximize IGF production -greater muscle protein synthesis in Type II 3 -protein quality and quantity important creatine and protein supplementation Ans: -greatest increase in lean tissue mass, and strength when taking whey protein AND creatine, not just whey protein or placebo
