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

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.
