An untrained person going to higher altitude for training can have maximum anabolic effect by: (AIPG 2007)



A Decrease in workload, increase in duration of exercise

B Decrease in work load

C Increase in work load, increase in duration of exercise

D Increase in work load, decrease in duration of exercise

Ans. D Increase in work load, decrease in duration of exercise

I. Exercise increases oxygen requirement while at high altitudes the oxygen availability is poor.

II. Exercise performed at high altitudes hastens the process of acclimatization

III. Exercise performance is impaired at high altitude even after short term acclimatization.

IV. Regular maximal strength exercise induces synthesis of more myofibrils and hence hypertrophy of active muscle cell, thereby producing maximal anabolic effect.

V. One of the cardinal principles of muscle development during athletic training is the following:

a. Muscles that function under no load, even if they are exercised for hours on end, increase little in strength.

At the other extreme, muscles that contract at more than 50 per cent maximal force of contraction will develop strength rapidly even if the contractions are performed only a few times each day. Using this principle, experiments on muscle building have shown that six nearly maximal muscle contractions performed in three sets 3 days a week give approximately optimal increase in muscle strength, without producing chronic muscle fatigue. (Ref: GUYTON Textbook of Medical Physiology 11th ed. Pg 1060)

b. But for better acclimatization there should be decrease in workload (resistance) and increase in duration of exercise which increases the endurance.

Endurance exercise or endurance training consists of performing low- to medium-intensity exercise for long periods of time. If the workload is increased it leads to increased oxygen demand and results in low exercise capacity due to low oxygen availability.
