- ANSWER Red Slow; Red Fast; White Fast Depleting energy recruitment results in increased muscle energy storage, but minimizes the involvement and growth of the __________________ motor units, which are known to have the greatest potential for growth. - ANSWER white, fast twitch This type of training, also known as 'power training' or Olympic style lifting, is where the athlete lifts, accelerates, and then immediately releases the weight, rather than slowly lowering it, forcing the recruitment of fast twitch muscle fibers. - ANSWER Ballistic training Performing Olympic style lifting causing a maximum contraction against a sub-maximal resistance, and forcing the recruitment of fast twitch fibers, is this type of motor unit recruitment: - ANSWER Contractile Speed Recruitment A stretching technique that uses the reflexive relaxation reaction of the antagonist muscle/s/ during the contraction is known as: - ANSWER Proprioceptive Neural Facilitation (PNF) This sensory nerve ending; embedded among the fibers of a tendon, protects against too much contractile force by 'shutting down' the muscle contraction just short of injury. - ANSWER Golgi Tendon Organ (GTO) Is "The Pump" good for size and strength increase? - ANSWER No, because it inhibits contractions causing premature failure The greater the oxygen taken up by the muscles during resistance exercise, the slower the use of - ANSWER stored muscle glycogen During what rep range does Myofibril failure occur? - ANSWER 4 to 6 rep range Intermediate failure occurs to what type of muscle fiber? - ANSWER Red, fast twitch During what rep range does Mitochondrial failure occur? - ANSWER 20 to 25 rep range Resistance exercise and a healthy diet will promote the body's use of ______________ to provide fatty acids and glycerol to replete the exhausted muscle stores. - ANSWER adipose tissue To optimize the fat conversion effects of resistance training, perform: - ANSWER high rep, low intensity, long duration using compound movements What are the smooth muscles in the body?

It does this by secreting the hormones: - ANSWER glucagon and insulin Which hormone is responsible for removing glucose from the blood stream? - ANSWER Insulin Basically nutrient metabolism can be broken up into two (2) distinct parts: - ANSWER Anabolism (the synthesis of all compounds needed by the cell) & Catabolism (the breakdown of molecules for energy) Simple sugars are taken up in the blood rapidly, but the muscles and liver can only take up the product, glucose, very slowly; therefore, if there is an over-abundance of glucose to be stored as the result of ingesting too many simple sugars - where is it stored? - ANSWER Fat cells Which of the following would be a reason that the liver would not be able to provide glucose for the blood? - ANSWER Over-exertive exercise; Extreme dieting or fasting; Liver disease or failure When is the optimal time for ingesting simple sugars? - ANSWER Immediately following an intense workout _________ fiber is not digestible; _______ fiber is digestible. - ANSWER Insoluble; soluble At least how many grams of carbohydrates should be ingested daily, by the average healthy adult, to spare amino acids, proteins and other energy reserves from being converted and used for energy? - ANSWER 156 grams The only usable form of simple sugar in the body is: - ANSWER glucose In the absence of ______ during intense aerobic activity, muscle tissue will be ____________ to provide for the balance of the energy needed to keep up with demand. - ANSWER glucose; cannibalized A method for avoiding the occurrence of cannibalism of intracellular proteins in the working muscles during intense resistance exercise is to: - ANSWER Eat protein regularly and ingest an easily absorbable carbohydrate about 15 minutes before workouts. If your client struggles with weight loss, it could be because of: - ANSWER heredity factors; over-consumption of 'junk' food Ingested fats are broken down into: - ANSWER Triglycerides, phospholipids, cholesterols ____________ is the packaged form of broken down fats that provides for fat transport to adipose tissue or the liver. - ANSWER Chylomicrons When protein is ingested, it moves to the stomach where it is acted on by the enzyme - ANSWER Pepsin How many grams of protein can be assimilated in 3 to 4 hours? - ANSWER 20 An amino acid may enter the metabolic processes as either ________ or __________. - ANSWER pyruvate ; acetyl CoA If the duration of intense exercise is too great, _________ are depleted and must be replaced immediately, this replenishment takes precedence over tissue repair. - ANSWER Catalysts Proteins become broken down into: - ANSWER Amino acids When your are excreting more nitrogen than you are ingesting, you are: - ANSWER Decreasing lean tissue What is the only form of energy, manufactured by the mitochondria, that muscles can use? - ANSWER Adenosine Triphosphate (ATP) The chief carbohydrate storage form of glucose is: - ANSWER Muscle Glycogen How many seconds of ATP are stored in cells for immediate use? - ANSWER 4 seconds During a muscle contraction, the muscle cell membrane is: - ANSWER Impermeable; nothing can get in or out of the cells The production of ATP in the absence of oxygen is called: - ANSWER Anaerobic glycolysis ________ is the end product of glycolysis in the presence of oxygen. - ANSWER Pyruvate Aerobic metabolism is also called: - ANSWER Cell respiration [Show More]
