Question

Resistance-training can be a high-intensity exercise, so one must be careful that the energy expended does not result in a negative energy balance, thus defeating the original purpose of the training.a) trueb) false

Answer 1

Answer:

B. False

Explanation:

Resistance training is any exercise that causes the muscles to contract against an external resistance with the expectation of increases in strength, power, hypertrophy, and/or endurance. The external resistance can be dumbbells, exercise tubing, your own body weight, bricks, bottles of water, or any other object that causes the muscles to contract.

It may improve several risk factors associated with coronary heart disease, such as increased levels of HDL cholesterol and improved glucose metabolism

How Much Resistance Exercise Should I Do?

The American College of Sports Medicine recommends that resistance training should be progressive in nature (for example, follow the principle of progressive overload - see below for an explanation), individualized, and provide a stimulus to all the major muscle groups (chest, back, shoulders, arms, abdominals, and legs). They recommend that beginners do one set of eight to 10 exercises for the major muscle groups, eight to 12 repetitions (reps) to fatigue, two to three days per week (multiple-set regimens may provide greater benefits if time allows). For older and more frail people (approximately 50-60 years of age and above), they suggest that 10-15 repetitions may be more appropriate

The principle of progressive overload is universally accepted as the model that creates the greatest gains in strength.

Answer 2

• Answer:
• False.
• Explanation:
• Resistance-training is a  class of weight training  exercise performed  within limited period of time to increase and developed lean muscle mass especially of the legs and trunks.It involves alternating short  vigorous intensive exercise,(  30 seconds to 1 mint,) with low intensive recovery intervals or low intensity exercise for the same period of the vigorous exercise, while repeating the whole sequence again.
• Resistance training usually increases resting expenditure with increases muscle mass,(afterburn) thus an induvidual with high muscle mass aftr the exercise  will loose more calories/hour compare with a non exercise person of low muscle mass.
• In addition the afterburn also increases post-exercise oxygen consumption, which boost metabolism.Evidence has shown that HIE tends to burn more fats than carbohydrate during afterburn, thus promoting weight loss, increasing bone density  and cutting down bad cholesterol levels.
• The  increase fat metabolism,increases heart rate and lower blood pressure.
• The intensity exercise also reduces blood sugar and improve insulin resistance.
• Consequently, the energy expended during this period of intensive activity is not negative energy balance , but rather a compensatory stimulus  for the body to gain  the positive effects of the exercise on body metabolism.
