CISSN Study Questions with All Correct
Answers 100% Verified
Explain how carnosine is synthesized within the body - ANSWER-Carnosine
(constituent amino acids: L-histidine and beta-alanine)
Stored in the skeletal muscle. Beta-alanine is the rate limiting component and
supplementation of beta-alanine has shown to elevate carnosine levels in varied
populations. Which may improve performance and quality of training in athletes doing
strength and power sports.
SO Beta-alanine works by enhancing muscle carnosine concentrations
Beta-alanine is a non essential amino acid that is produced endogenously (substances
produced in) the liver.
Beta-alanine is acquired through consuming foods like poultry and meat.
What is a waxy maize starch and what effect does it have on blood glucose? -
ANSWER-A very slow digesting starch that blunts plasma and insulin response leading
to prolonged energy availability and satiety compared to rapidly digested starches .
Rice, barley, and corn. amylose and amylopectin.
Based on recent studies, which vitamin shows evidence of positivity affecting muscle
function? - ANSWER-vitamin D
The primary ergogenic nutrients in most ED and energy shots (ES) appear to be
carbohydrate and/or caffeine. - ANSWER-TRUE
What effects can a low carb diet have on prolonged physical activity? - ANSWER-
Decreased glycogen synthesis, decreased performance, overreaching/overtaining.
,Approximately how many days of heat exposure does it take to fully acclimate to
exercising in the heat? - ANSWER-Complete acclimation takes up to 14 days.
What is needed for gluconeogenesis in humans? Give examples of gluconeogeic
precursors - ANSWER-Gluconeogenesis relies on lactate, pyruvate, glycerol, and
certain amino acids (glutamine and alanine)
What effect does long-term coffee consumption have on Type 2 Diabetes? - ANSWER-
Studies show that moderate consumption of both caffeinated and decaf coffee may
lower risk of DM2 in younger and middle aged women. Coffee constituents other than
caffeine may affect the development of DM2
What effect does supplementing with WPI have on muscle damage? - ANSWER-A.)
major finding is whey protein attenuates the impairment in isometric and isokinetic
muscle forces during recovery from exercise-induced muscle injury.
B.) One study shows that whey protein in a partially hydrolyzed (pre-digested) from
improves strength recovery rates, possibly due to an increase in the rate of repair
process and/or a reduction in the extent of damage, from intense training, in particular,
eccentric exercise that is commonly used in weight training.
When glycogen stores are depleted, what macro becomes the predominant fuel source
during distance running? - ANSWER-Fat (oxidation)
What are the effects of pre-exercise dehydration on thermoregulation and performance?
- ANSWER-Decreased thermoregulation and performance.
What are the effects of L-anayl-L-Glutamine supplementation on time-to-exhaustion and
dehydration stress? - ANSWER-Results show that AG supplementation provide a
significant ergogenic benefit by increasing time to exhaustion during a mild hydration
,stress. This ergogenic effect was likely mediated by an enhanced fluid electrolyte
uptake.
What is HICA and what are the effects of its supplementation for a period of 4 weeks? -
ANSWER-A. Alfa-Hydroxy-isocaproic acid is and end product of leucine metabolism in
human tissues such as muscle and connective tissue. According the clinical and
experimental studies, HICA can be considered as an anti-catabolic substance. The
present study investigated the effects of HICA supplementation on body comp, delayed
onset of muscle soreness (DOMS) and physical performance of athletes during a
training period.
B. Already a 4-week HICA supplementation of 1.5g/day leads to small increase in
muscles mass during an intensive training period in soccer athletes.
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. - ANSWER-TRUE
Consuming ED 10-60 minutes before exercise can improve mental focus, alertness,
anaerobic performance, and/or endurance performance. - ANSWER-TRUE
What is the BOD-POD? DEXA? - ANSWER-A body composition recording device that
uses air displacement plethysmograph
DEXA: dual energy x-ray absorptiometer used to measure bone mineral density (BMD)
to measure bone loss.
Compare fat and carbohydrate oxidation during exercise. Under what conditions does
one fuel source predominate over the other? - ANSWER-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? - ANSWER-
A. Betaine supplementation improves muscular endurance in active college age males
B. has 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 roll in buffing exercised induced
acidosis
Chronic heavy resistance training causes what adaptations in skeletal muscle? -
ANSWER-A. Increase in muscle strength and size (hypertrophy of cross-sectional area
of the muscle fibers)
B. Greater increase in type 2 (II) muscle fibers
C. Shift in fiber types type 2b (IIx) to 2a (IIa)
Regular aerobic training causes what adaptations in skeletal muscle - ANSWER-A.
Increased oxidative capacity, increased number and size of mitochondria
B. Adaptation of muscle fibers: Type 2A to type 1 slow twitch, meaning there is more
muscle fibers to carry out aerobic ATP production.
C. Increased oxidation of fats and glycogen.
D. Decreased lactic acid production
E. Increased a-vo2 difference (arteriovenous oxygen difference)
