Explanation / Answer

25. The recommended fat intake from the American Heart Association should be between 20 to 35 percent of your total caloric intake(5% to 6% of calories from saturated fat), that means if you are consuming 2,000 calories a day, a healthy fat intake will be 400 to 700 calories.

26. 25 gm fibres per day(According to the American Heart Association, the daily value for fiber is 25 grams per day on a 2,000-calorie diet for adults)

27. Resistance training also is known as weight training.Following a proper breathing pattern is very important, one should be highly alert and should have good control to avoid weight room related injuries.While strength training exercises the person should inhale during the eccentric portion of the said exercise, and exhale during the concentric phase eg. Exhale when lifting; inhale while lowering; hold it hard during the lift; breathe out with effort while doing lifting exercises

28.The prime movers of ankle plantar flexion are the soleus and gastrocnemius muscles.

It is the coordinated movement of the several muscles in your ankle, foot, and leg to produce flexion of foot at ankle joint.T

a) Gastrocnemius: This muscle makes up half of your calf muscle. It runs down the back of your lower leg, from behind your knee to the Achilles tendon in your heel.main muscle involved in flexion

b) Soleus: one of the calf muscles in the back of the leg. It connects to the Achilles tendon at the heel. You need this muscle to push your foot away from the ground.

other muscles involved with the minor role are Plantaris,Flexor hallucis longus, Flexor digitorum longus,Tibialis posterior, Peroneus longus, Peroneus brevis

29.The energy to perform long-term exercise (i.e., >15 min) comes primarily from aerobic metabolism.

After about 3 seconds of exercise, the muscle cells burn off their supply of ATP, then the phosphagen system kicks in, this supplies energy for 8 to 10 seconds. This system is the major energy system used by the muscles when rapid acceleration, short-duration exercise occurs, such as a 100-meter sprint. Cells split glycogen into glucose and lactic acid, which produces enough ATP to last about 90 seconds of exercise. When exercise continues longer, then this glycogen-lactic acid system kicks in. Short-distance exercises, for example, a 400-meter dash or 100-meter swim, will utilize this system. Lastly, if exercise continues, then aerobic respiration takes over. Aerobic respiration uses carbohydrates, fats, and proteins to make energy lasting as long as the fuel lasts.
