Question

In the previous question, you identified the individual who was completing aerobic exercise. This aerobic exercise helps to increase     

a. flexibility

b. cardiorespiratory

c.musculoskeletal fitness

, or the ability to perform moderate-to-high-intensity activity involving large muscle groups for long periods of time.

Identify the activities that would most likely improve an individual’s cardiorespiratory fitness.  Check all that apply.

a.Front squatting

b.Running

c.Swimming

d.Yoga

The excitation, contraction, and relaxation of skeletal muscle require the use of ATP. Because only limited stores of ATP are immediately available in muscle tissue, ATP must be continually supplied if contractile activity is to continue.

Depending on the type of movement or exercise, one or more pathways can be used to provide the most efficient way of supplying the ATP.

For example, a cross-country skier who skis continuously for two hours during a training exercise will need....

a.short bursts.

b. a sustained source

of ATP. As a result, which of the following pathways would be best suited to this type of activity?

a.Using creatine phosphate

b.Glycolysis

c.Oxidative phosphorylation

To prepare for the cross-country meet, a skier decides to significantly increase the amount of carbohydrates in his diet (a technique also known as carbohydrate loading). Why might this be beneficial to the cross-country skier? Check all that apply.

a.Carbohydrates are used to build actin filaments in the myofibrils, which increases muscle bulk and performance.

b.The liver can store copious amounts of ingested carbohydrates as glycogen, which can then be slowly broken down to release the glucose needed to fuel aerobic respiration.

c.As long as oxygen is present, the glucose stored in the ingested carbohydrates can provide a steady stream of ATP, thus meeting the demands of prolonged periods of exercise.

d.Eating more carbohydrates leads to more glycogen stores in muscles, which then equates to larger energy stores for short, explosive bouts of energy use.

Answer 1

Q. No. 1. Answer : is " c ".

An aerobic exercises help to increase musculo skeletal fitness. Or the ability to perform moderate to high intensity of activities for involving large muscle groups for long period of time.

Because through aerobic exercises the person may get adequate oxygen levels, what ever the cells needed In the body.

So the answer is " c ".

Q. No. 2. Answers are : " b ", " c ", " d ".

" b " is running and " c " is swimming .

These both are aerobic activities these will improves the oxygen supply to the muscles, so that what ever the data and carbohydrates are there in the body may burns, so that the risk of heart diseases may decreases and cardiovascular fitness may increases.

Is " d " .

That is yoga can improves the cardio respiratory fitness because through in this yoga we will do physical activity, breathing and meditation.

So that the risk of cardiovascular diseases may decreases and fitness may increases.

Q. No. 3. Answer : is " a " and " b ".

Because sustained source of ATP through " Creatinine phosphate " and glycolysis, because more energy ATP molecules produced by those only.

So the answer is " a and b ".

Q. No. 4. Answer : is " d "

Because by eating carbohydrates leads to more glycogen stores in muscles, which then equates to larger energy stores for short explosive bouts of energy use to do an activity.
