• VO2 max is the measurment of maximum amount of oxygen a person can utilize during intense excercise.
• VO2 is an index of the body’s efficiency at producing work.
• There are many factors affecting which can influence VO2 max , they are heredity , training, age, gender, and body composition.
• Generally VO2 max declines with age about 2% per year after 30 years.Hence option B and D are wrong because the age of person is 50 and 55 years .
• Males typically have a greater oxygen consumption value than females .Hence option A is wrong.
• Higher VO2 max allows one to produce more energy , thereby performing more work.Hence a person with young age and moderate fit will have high improvement.
