5-10

Which of the following training intensities of exercise are likely to elicit the greatest percentage of improvement in VO2 max? - <50% VO2 max - 65-70% VO2 max - 80-100% VO2 max - 55-60% VO2 max

80-100% VO2 max

Which of the following is NOT an important factor that contributes to performance in endurance events? - high VO2 max - superior exercise efficiency/economy - high anaerobic capacity - high lactate threshold

high anaerobic capacity

Following an acute bout of endurance exercise training, the increase in mitochondrial biogenesis occurs within _____ following the completion of the exercise session. - hours - days - minutes - seconds

hours

Most, if not all, of the increase in muscle size due to strength training is the result of _________. - both hypertrophy and hyperplasia contribute equally - an increase in muscle water content - hyperplasia - hypertrophy

hypertrophy

Endurance training has been shown to reduce the oxygen deficit in subjects performing a bout of submaximal exercise. This is likely due to - a greater anaerobic capacity. - an increased maximal cardiac output. - a decreased resting heart rate. - increases in the number of mitochondria and capillaries.

increase in the number of mitochondria and capillaries

Which of the following endurance training adaptations assist in maintaining acid-base balance during exercise? - increased glycolytic capacity - increased mitochondrial volume in skeletal muscle - decreased beta oxidation capacity - increased M4 form of LDH

increased mitochondrial volume in skeletal muscle

Which of the following factors does NOT contribute to the endurance exercise training-induced improvement in stroke volume during exercise? - increased cardiac contractility - increased end-diastolic volume - increased peripheral resistance - decrease in total peripheral resistance

increased peripheral resistance

Delayed onset of muscle soreness is likely due to ____________. - lactic acid buildup in muscles - depletion of muscle glycogen - muscle cramps - microscopic tears in the muscle resulting in calcium release from the sarcoplasmic reticulum

microscopic tears in the muscle resulting in calcium release from the sarcoplasmic reticulum

Which of the following is NOT true about strength training comparisons between men and women? - When muscle force production is normalized to cross-sectional area, men and women are similar. - Men and women generally exhibit the same absolute levels of strength. - All of these answers are correct. - Men typically have more muscle mass than women.

Men and women generally exhibit the same absolute levels of strength.

The best protection against heat stroke and heat exhaustion is - hydrating before exercise. - wearing light-colored clothing. - taking salt tablets. - acclimatization.

acclimation

Preceding a static stretch with an isometric contraction of the muscle group to be stretched _____________. - is effective in improving muscle relaxation - is called proprioceptive neuromuscular facilitation - All of these answers are correct - can activate the Golgi tendon organ

all of these answers are correct

The enhanced capacity of the trained muscle to use fatty acids as a fuel results in - decreased utilization of muscle glycogen. - increased uptake of fatty acids. - sparing of blood glucose. - all of these answers are correct.

all of these answers are correct

Which of the following factors have the ability to impact the risk of developing heat injury during exercise? - All of these answers are correct - acclimatization - wind - hydration status

all of these answers are correct

The principle of specificity of training refers to the fact that exercise training is specific to - the muscles involved in the activity. - all of these are correct. - the fiber types recruited. - the principal energy system (i.e., aerobic vs. anaerobic) involved in the activity.

all of these are correct

Which of the following is NOT a common laboratory test used to quantify endurance exercise potential? - lactate threshold test - tests of movement efficiency (e.g., running economy) - All of these are correct - determination of ventilatory threshold

all of these are correct

Which of the following statements are true about the effect of endurance training or detraining on mitochondria volume in human skeletal muscle? - Seven days of detraining can reduce mitochondrial volume by 50% below the trained level. - All of these are true. - After a period of detraining, approximately 4 weeks of retraining is required to regain the lost mitochondrial volume. - Five weeks of endurance training can increase skeletal muscle mitochondrial volume by two times about normal.

all of these are true

The "RICE" treatment is recommended to improve the recovery from delayed onset muscle soreness. RICE is an abbreviation for _________________. - rest, ice, compression, and elevation - rest, intensity, cold, and elevation - None of these answers is correct - recovery, ice, compression, and elevation

rest, ice, compression, and elevation

When an athlete stops exercise training, the training effect is quickly lost. This illustrates the concept of ________. - overload - reversibility - specificity - the "ten percent rule."

reversibility

Endurance training results in increased mitochondrial and capillary density in muscle but has no effect on muscle glycolytic capacity. This is an example of what training principle? - none of these - overload - reversibility - specificity

specificity

Endurance training results in increased mitochondrial and capillary density in muscle but has no effect on muscle glycolytic capacity. This is an example of what training principle? - overload - reversibility - none of these - specificity

specificity

Cross-sectional studies demonstrate that the physiological variable responsible for the large variation in VO2 max across the normal (untrained) population is maximal - systolic blood pressure. - stroke volume. - arteriovenous O2 difference. - heart rate.

stroke volume

HIIT training is advantageous for which of the following reasons? - workout variation options are plentiful - training sessions are time-efficient - Both training sessions are time-efficient and workout variation options are plentiful are correct - the warm-up and cool-down are proportionately shorter than moderate intensity continuous training

Both training sessions are time-efficient and workout variation options are plentiful are correct

The term overload, when used in conjunction with a sport conditioning program, is defined as: - exercise training that stresses the cardiovascular system and/or skeletal muscles above a level to which it's accustomed. - exercise that results in emotional stress. - exercise performed above 90% VO2 max. - injury or damage a muscle group.

exercise training that stresses the cardiovascular system and/or skeletal muscles above a level to which it's accustomed.
