CISSN STUDY GUIDE QUESTIONS AND
ANSWERS 2024/2025
based on recent studies, which vitamin shows evidence of positively affecting muscle function?
→ vitamin D
the primary ergogenic nutrients in most ED and ES appear to be carbohydrate and/or
caffeine. True or False
→ true. caffeine is the most common ingredient utilized in energy drinks.
the ergogenic value of caffeine on mental and physical performance has been well
established but the potential additive benefits of other nutrients contained in ED and ES
remains to be determined. True or False
→ true
consuming ED 10-60 minutes before exercise can improve mental focus, alertness, anaerobic
performance, and/or endurance performance. True or false
→ false not anaerobic performance. only aerobic endurance
what effect does long-term coffee consumption have on type 2 diabetes?
→ results suggest that moderate consumption of both caffeinated and decaffeinated
coffee may lower risk of type 2 diabetes in younger and middle-aged women. coffee
constituents other than caffeine may affect the development of type 2 diabetes.
when glycogen stores are depleted, what macronutrient becomes the predominant fuel source
approximately how many days of heat exposure does it take to fully acclimate to exercising
in the heat?
→ complete acclimation takes up to 14 days
what is a Bod-Pod
→ a body composition recording device that uses air displacement plethysmography
→
→ - DXA is most accurate
compare fat and carbohydrate oxidation during exercise. under what conditions does one fuel
source predominate over the other
→ a. fat oxidation primarily occurs at low intensity long duration exercise
→ b. carbohydrates are oxidized preferentially during higher intensity exercise
what effect does betaine supplementation have on exercise performance?
→ a. betaine supplementation improves muscular endurance in active college age males
→ b. has been shown to increase power, force, and maintenance *****
→ c. loading phase (4 weeks) of beta-alanine supplementation is essential for increasing
carnosine levels. thus carnosine plays a significant roe in buffering exercise induced
acidosis
chronic heavy resistance training causes what adaptations in skeletal muscle
→ a. increase in muscle strength and size (hypertrophy of cross-sectional area of the
muscle fibers)
→ b. greater increase in type 2 muscle fibers
→ c. shift in fiber type 2b to 2a
regular aerobic training causes what adaptation in skeletal muscle
→ 1. increased oxidative capacity, increased number and size of mitochondria
→ 2. adaptation of muscle fibers: type 2A to type 1 slow twitch, meaning there is more
muscles fibers to carry out aerobic
→ ATP production.
→ 2.increase oxidation of fats and glycogen
→ 3. decreased lactic acid production
→ 4. increased AVO2 Diff.
→ 5. increase in enzymes of metabolic pathways involved in oxidative metabolism
→ - succinate dehydrogenase, malate dehydrogenase, (krebs cycle, tricarboxylic acid
cycle)
what percentage of creatine is stored in skeletal muscle
→ 95% - 2/3rds stored as phosphocreatine (PCr)
what is beta-alanine and what does it do when ingested during intense training?
