What two factors contribute to children having less of a tolerance for temperature extremes, especially
when exercising?
A) Glycolytic enzymes are lower, higher submaximal oxygen demand
B) Lack of hydration, children do not exhibit maximum oxygen uptake
C) Higher submaximal oxygen demand, Lower sweating rate
D) Lack of hydration, lower sweating rate

- True or false, children exhibit a plateau in oxygen uptake similar to adults?
• True
• False
False
- True or false, children do not produce sufficient levels of glycolytic enzymes to be able to sustain bouts of high-intensity exercise?
• True
• False
True
Answer: A, True. Children produce only low levels of many key enzymes.
- True or false, resistance training for health and fitness conditioning in youth also results in a higher risk of injury when compared with many popular sports
• True
• False
Answer: B, False. Studies have shown that resistance training for children is actually safer than most sports.
- True or false, a recent review of the literature suggests that untrained children can improve their strength by an average of 30 to 40% after 8 weeks of progressive resistance training?
• True
• False
Answer: A, True. Even without gains in muscles mass, children can significantly improve strength in as little as 8 weeks.
- True or false, by the middle of this century, it is estimated that 87 million people or roughly 21% of the entire U.S. population will be 65 years of age or older?
• True
• False
True
