A 4-6 week endurance training regiment has been shown to have the following effect on myoglobin?a.) increased concentration in skeletal musclesb.) increased concentration in blood plasma levelsc.) research studies can not positively corroborate any effectd.) decreased concentration in skeletal musclesReview Question #22.) A 27 week endurance training program increased mitochondrial size by how much?a.) 25%b.) 35%c.) 45%d.) 55Review Question #33.) How will succinate dehydrogenase (SDH) concentrations be affected from a marathon training program (~6 months)?a.) no effect – glycolytic enzymes are not affectedb.) research studies have yet to determine the role of SDH c.) an initial three-fold increase that plateaus after 4 monthsd.) a linear response to training volumeReview Question #4, 54.) TRUE/FALSEConcentration of oxidative enzymes have been positively correlated with maximal aerobic capacity5.) What does this signify?The fact that increased oxidative enzymes are NOT correlated with increased aerobic capacity suggests that other factors are responsible for improving aerobic capacity (i.e. capillary density).Review Question #66.) Which of the following is NOT a reason for decreased reliance of fat as an energy substrate at higher intensities?a.) Inadequate transport of albuminb.) ↑ circulating FFA levelsc.) ↓ rate of lipolysis of intramuscular trigylceride storesd.) ↓ uptake of circulating FFA by muscleReview Question #77.) How will an endurance training program influence the utilization of fat?An endurance training program will allow fats to be oxidized and used for energy at higher intensities. This spares glycogen stores and prevents the buildup of lactate – all positive effects allowing exercise to continue for longer and at a higher intensityReview Question #88.) TRUE/FALSEEndurance training can triple the amount of intramuscular stores of triglycerides.Review Question #99.) List three positive metabolic adaptations as a result of endurance training on oxidative metabolism.1.) increased capillary content2.) increased oxidative enzyme concentration3.) increased mitochondrial size and #Review Question #1010.) Explain how a high-intensity training program can increase blood lactate concentrations by 9.6%.A high-intensity training program increases the buffering capacity within muscle cells allowing a greater TOLERATION of lactic acid levels. Biocarbonates and muscle phosphates act as BUFFERS by combining with H+ released from lactic acid.Review Question
