How can physical activity help prevent a heart attack?
LuckyWell [14K]

Physical activity can prevent a heart attack because you're increasing your blood flow through your body. You're also making you cholesterol ratio between you "good and bad" cholesterol balance out. Example, if you have a high "bad cholesterol" (LDL level) and a high "good cholesterol" (HDL level), the exercising will help increase your HDL levels and lower your LDL cholesterol.


Also, a lot of people don't realize that the younger you are and have a heart attack, the LEAST likely you will survive. This is opposite of a normal idiopathy.

The younger we are, the less "added pathways" our veins/arteries have within our heart. Exercising can actually create these additional pathways within our heart to held reduce the risk of a heart attack and if someone does have a heart attack, they have addition pathways for blood to flow and less of the heart muscle will die.

Kelly (66 kg) is a 48-year-old race walker who participates in half marathons. She walks 5 to 6 days per week, 1 to
natulia [17]

Answer:

To keep glycogen levels as high as possible, Kelly should consume 6-10 g of carbohydrates for every 1 kilo of her body weight, which is equivalent to 60 - 70% of her daily caloric value. In addition, it is appropriate for her to do this for four or three days in the week before the race.

Explanation:

Kelly is an athlete and needs fast energy, that is, she needs to consume a large but appropriate number of carbohydrates that will be metabolized quickly by her body, during the race, and will give her the energy necessary to achieve good results in the marathon that she will participate.

For this, she must seek a health professional who can guide her to an appropriate and effective diet.

It is recommended that runners consume 6 - 10 grams of carbohydrates for every 1 kilo they have. In the case of Kelly, she should consume 396 - 660 grams of carbohydrate per day to achieve a good energy value.

Imagine that a researcher performs an experiment examining the effects of nutrition on memory. Each subject is randomly assigned
dem82 [27]

Answer:

Options <em>A, B and C</em> are correct.

Explanation:

A. Nutrition impacts memory when people are on the diet for three months

This option is correct because it was found that being on a high- protein or high-fiber diet for three months resulted in a significant improvement on memory performance tests. Note that "significant" here refers to statistical significance- which means the result is not due to random chance.

B. Nutrition has a bigger impact on memory when people are on the diet for three months than when they are on the diet for one month

This option is correct because when subjects were on a month long diet of either a standard diet, high- protein or high-fiber diet, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition is not statistically significant. This means that the subjects on the high-protein and high-fiber groups did not conclusively do better on memory tests, and the result could be attributed to chance or other extraneous factors.

On the other hand, when subjects were on a high- protein or high-fiber diet for three months, it resulted in a significant improvement on memory performance tests- which means the result was not due to random chance.

C. There is not sufficient evidence to conclude that nutrition impacts memory when people are on the diet for one month

This option is correct because as stated above, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition was not statistically significant- which means the results could be attributed to chance.
