Progressive Resistance Exercise Progressive resistance exercise (PRE) is a method of increasing the ability of muscles to generate force. The principles of PRE for increasing force production in muscles have remained unchanged for almost 60 years. These principles are (1) to perform a small number of repetitions until fatigued, (2) to allow suffi cient rest between exercises for recovery, and (3) to increase the resistance as the ability to generate force increases. Traditionally, PRE has been used by young, healthy adults to improve athletic performance. A student decided to incorporate PRE into his exercise program. He did not know how to determine when he had allowed suffi cient rest between exercises for recovery. He hypothesized that waiting for his pulse to return to normal would probably be a good indication. 80 Explain why allowing his pulse rate to return to normal might be a good indication that he had waited long enough for recovery.
What is Acceptable responses include, but are not limited to: — If his pulse rate were normal, it would indicate that the muscles have removed wastes and have enough energy available to resume exercising. — Normal pulse rate is the same as resting pulse rate. — When his pulse rate returns to normal, it indicates that there is no longer a need for more oxygen/excretion of excess carbon dioxide. — This shows that the body has returned to a homeostatic balance.

Students wanted to try PRE to increase their ability to rapidly squeeze a clothespin. They thought if they could do this, they could challenge another class to a clothespin squeezing competition and win. Which steps should the students take to follow the principles of PRE? (1) Measure their pulse rate after squeezing the clothespin until fatigued. Then increase the resistance of the clothespin for the next trial. (2) Squeeze a clothespin until fatigued, rest, and repeat. Over time, they should gradually increase the re- sistance of the clothespins they are squeezing. (3) Measure their pulse rate, squeeze a clothespin for one minute, rest, and measure their pulse rate. (4) Squeeze a clothespin for as long as they can, measure their pulse rate, rest, eat some candy. Increase the resistance of the clothespin for the next trial.

Students following the principles of PRE monitored their ability to lift weights. Which observation would indicate that their exercise program was successful? (1) They could eventually lift heavier weights than when they started. (2) Their pulse rate increased more rapidly as they kept lifting weights. (3) The number of weights their group could lift during competition decreased. (4) Males and females could lift the same weight an equal number of times during competition.

Identify one waste product that is released during exercise. Explain how this waste product leaves the body.
What is Allow 1 credit for identifying one waste product that is released during exercise and explaining how this waste product leaves the body. Acceptable responses include, but are not limited to: Carbon dioxide: — It diffuses into the blood and is carried to the lungs, where it is exhaled. — As you exercise, carbon dioxide is carried to the lungs, where it is exhaled. — Carbon dioxide is exhaled. Sweat: — contains salts and other minerals, passes out through pores in the skin — evaporates, cooling off the body — leaves as moisture Heat: — It is radiated from the skin.
