Question 7 1 pts Which of the following is NOT a correct statement about fitness and health? O Excessive exercise can begin to negatively affect health. O Cardiorespiratory recommendations must be met in order to reap health benefits. O Resistance activities do not have to include weights to be beneficial. O Body composition improves as activity supports lean body tissues and reduces body fat. Question 8 1 pts Kayla read that taking a sodium bicarbonate supplement can enhance exercise capacity. As an endurance athlete, this potential effect interests Kayla, so she buys a sodium bicarbonate supplement to try. If she experiences an unpleasant side effect from the supplement, what will it most likely be? O Diarrhea O 'Pins and needles' sensation O Acne O Nervousness

QUESTION 1 Which of the following is not considered a health benefit of aerobic activity: it lowers resting heart rate. it trains the body to deliver oxygen more efficiently. it reduces cardiovascular disease. it decreases the effectiveness of muscles to use oxygen for energy metabolism. QUESTION 2 Hyponatremia is caused when an athlete: consumes too much water that dilutes sodium levels. consumes too many sports drinks. does not consume enough water. properly hydrates with electrolytes. QUESTION 3 Muscular endurance refers to: the concept that the body will adapt to stresses placed on it. the amount of total force that can be produced from a single contraction of a muscle. the ability of a muscle group to continue movement over time. QUESTION 4 Staying physically active is not necessary to achieve optimal health. True. False.

QUESTION 34: Caffeine can increase fatty acid mobilization by inhibiting phosphodiesterase, increasing the formation of cyclic AMP, and activating protein kinase. All of these answers are correct. QUESTION 35: Although the drug erythropoietin can increase endurance performance by increasing the transport of oxygen, it can also impair blood flow if hemoglobin concentrations reach high levels.
