Which of the following is a benefit of a regular strength-training program quizlet

hypertrophy-an increase in muscle fiber size.

hyperplasia-increase in the number of muscle fibers.

isotonic exercise-a type of exercise in which there is movement of a body part. most exercise or sports skills are isotonic exercise. also called dynamic exercise.

isometric exercise- a type of exercise in which muscular tension is developed but the body part does not move. also called static exercise.

isokinetic exercise-a type of exercise that can include concentric or eccentric muscle actions performed at a constant speed using a specialized machine.

motor unit-a motor nerve and all of the muscle fibers it controls.

progressive resistance exercise-a motor nerve and all of the muscle fibers it controls.

static contraction-'static' - meaning still/motionless, and 'contraction' - meaning to tense the muscles and use them. So the idea then in static contraction is simply to force your muscles to work without actually moving. /
Isometrics are static contractions. By static contractions we mean muscular contractions where the muscle is contracting without actually moving. An isometric contractions occurs any time you are holding a weight in a fixed position (a yielding isometric contraction) or pushing/puling against an immovable object (overcoming isometric contraction).

valsalva maneuver- breath holding during an intense muscle contraction; can reduce blood flow to the brain and cause dizziness and fainting.

For general good health, the 2008 Physical Activity Guidelines for Americans recommends that adults get a minimum of 2-1/2 hours per week of moderate-intensity aerobic activity. (37) Yet many people may need more than 2-1/2 hours of moderate intensity activity a week to stay at a stable weight. (37)

The Women's Health Study, for example, followed 34,000 middle-aged women for 13 years to see just how much physical activity they needed to stay within 5 pounds of their weight at the start of the study. Researchers found that women who were in the normal weight range at the start of the study needed the equivalent of an hour a day of physical activity to stay at a steady weight.(43)
If you are exercising mainly to lose weight, 30 minutes or so a day may be effective in conjunction with a healthy diet. (44)
If you currently don't exercise and aren't very active during the day, any increase in exercise or physical activity is good for you.

Children and adolescents should get at least 1 hour or more a day of physical activity in age-appropriate activities, spending most of that engaged in moderate- or vigorous-intensity aerobic activities. They should partake in vigorous-intensity aerobic activity on at least three days of the week, and include muscle-strengthening and bone strengthening activities on at least three days of the week.

Healthy adults should get a minimum of 2-1/2 hours per week of moderate-intensity aerobic activity, or a minimum of 1-1/4 hours per week of vigorous-intensity aerobic activity, or a combination of the two. That could mean a brisk walk for 30 minutes a day, five days a week; a high-intensity spinning class one day for 45 minutes, plus a half hour jog another day; or some other combination of moderate and vigorous activity. Doubling the amount of activity (5 hours moderate- or 2-1/2 hours vigorous-intensity aerobic activity) provides even more health benefits. Adults should also aim to do muscle-strengthening activities at least two days a week.

Healthy older Adults should follow the guidelines for healthy adults. Older adults who cannot meet the guidelines for healthy adults because of chronic conditions should be as physically active as their abilities and conditions allow. People who have chronic conditions such as arthritis and type 2 diabetes should talk to a healthcare provider about the amount and type of activity that is best. Physical activity can help people manage chronic conditions, as long as the activities that individuals choose match their fitness level and abilities. Even just an hour a week of activity has health benefits. Older adults who are at risk of falling should include activities that promote balance. (37)

When talking about the benefits of exercise, keeping the heart and blood vessels healthy usually gets most of the attention. For many individuals, though, stretching and strength training exercises may be just as important.
Strength training, also known as resistance training, weight training, or muscle-strengthening activity, is one of the most beneficial components of a fitness program.
