Question

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

a.flexibility

b.musculoskeletal fitness

c. cardiorespiratory 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.

Cycling

Back squatting

Pilates

Jogging

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, an ice hockey player who engages in repeated bouts of high intensity, fast skating maneuvers will need

a.short bursts

b. a sustained source

of ATP. As a result, ice hockey players will typically use   respiration during a game.

a. anaerobic

b. aerobic

It might also be the case that this ice hockey player will take creatine supplements to boost his performance. Why might this be so? Check all that apply.

a.Eating more creatine leads to more creatine phosphate stores in muscles, which then equates to larger energy stores available for short, explosive bouts of energy use.

b.Creatine in the blood allows the body to absorb more oxygen, which helps to fuel ATP production in the muscle cells.

c.Creatine increases the speed with which neural signals reach the muscle.

d.Unlike oxidative phosphorylation, ATP can be formed within a fraction of a second from creatine phosphate sources, since only one enzymatic reaction is involved in this energy transfer.

Answer 1

Aerobic exercise helps to increase
a, cardiorespiratory fitness
The American heart association recommends aerobic exercise strengthen the heart and help reduce blood pressure and cholesterol. 40 minute moderate to vigours exerciser for 3 to 4 times a week can reduce asthma symptoms and pump blood efficiently throughout the body.
Activities that improve individual cardiorespiratory fitness
Jogging, cycling, pilates
endurance exercise activities include walking, jogging, swimming, biking can increase breathing and heart rate.
Ice hockey player takes creatinine supplements to boots the performance because
a, Eating more creatinine leads to more creatinine phosphate stores in muscle, which then equates to larger energy stores available for short, explosive bouts of energy use.
d, Unlike oxidate phosphorylation, ATP can be formed within a fraction of a second from creatinine phosphate source. since only one enzymatic reaction is involved in this energy transfer.
creatinine supplements increase muscular force and power, increase muscle mass, reduce fatigue in repeated bout activities.
