Lfit Unit 3 Muscular Fitness

1. Exercise that promotes muscle strength and mass also effectively increase bone mass and bone strength of the specific bones stressed.

True

False

Exercise that promotes muscle strength and mass can effectively increase bone mass and bone strength of the specific bones stressed. This is because when muscles contract during exercise, they pull on the bones, which in turn stimulates bone cells to produce new bone tissue. This process, known as bone remodeling, helps to increase bone density and strength. Therefore, engaging in exercises that target muscle strength and mass can have a positive impact on bone health.

2. Some evidence shows that resistance training may prevent and improve depression and anxiety, increase "energy" levels, and decrease fatigue, however further study of this effect is required.

True

False

Resistance training has been found to have positive effects on mental health, including preventing and improving depression and anxiety. It can also increase energy levels and decrease fatigue. However, more research is needed to fully understand and confirm these effects. Therefore, the statement is true.

3. Regular participation in resistance training can improve blood pressure in persons with prehypertension or stage 1 hypertension (chronic high blood pressure).

True

False

Regular participation in resistance training can improve blood pressure in persons with prehypertension or stage 1 hypertension. This is because resistance training helps strengthen the muscles, including the heart, which in turn improves cardiovascular health. By engaging in regular resistance training, individuals can reduce their blood pressure levels and potentially prevent or manage hypertension. Therefore, the statement is true.

4. Although muscular fitness has shown positive improvements for many health markers, the research does not show improvements in blood glucose or insulin sensitivity from regular participation in resistance training.

True

False

The statement implies that regular participation in resistance training does not lead to improvements in blood glucose or insulin sensitivity. However, this is not true. Research has shown that resistance training can indeed improve blood glucose control and insulin sensitivity. Therefore, the correct answer is False.

The statement implies that regular participation in resistance training does not lead to improvements in blood glucose or insulin sensitivity. However, this is not true. Research has shown that resistance training can indeed improve blood glucose control and insulin sensitivity. Therefore, the correct answer is False.

5. Which of the following are not associated with higher levels of strength? Choose all the appropriate options.

Better cardiometabolic risk factor profiles

Lower risk of all-cause mortality

Fewer cardiovascular disease events

Lower risk of developing functional limitations and other nonfatal diseases

None of these are associated with higher levels of strength

Higher levels of strength are associated with better cardiometabolic risk factor profiles, lower risk of all-cause mortality, fewer cardiovascular disease events, and lower risk of developing functional limitations and other nonfatal diseases.

Explanation

Higher levels of strength are associated with better cardiometabolic risk factor profiles, lower risk of all-cause mortality, fewer cardiovascular disease events, and lower risk of developing functional limitations and other nonfatal diseases.
