F
There is no benefit to neither static no dynamic balance as a result of regular strength training
F
Two basic types of muscular exercise are static and constant resistance
F
When muscles are not used, they grow weaker, stiffen, and hypertrophy
F
When muscles are stimulated by an increased workload, they atrophy
F

T
An example of a dynamic exercise is a sit up or push up
T
Benefits of strength training include weight control, time economy, increased bone strength, and flexibility
T
Correct exercise form is an often neglected but important factor in maximizing strength gains and minimizing risk of injury
T
Greatest strength gains are made with 2 to 3 days of recovery between sessions to allow muscle fibers to repair and grow
T
Hand and ankle weights should not be used during running and jumping activities due to increased risk of injury
T
Health conditions that should be checked by a doctor prior to initiating a weight training program include hernia, arthritis, or lower back problems
T
Improved muscular fitness contributes to improved balance, power coordination, and agility
T
Improvement in muscular fitness occurs during the recovery session between workouts
T
In a concentric contraction, a muscle shortens as it overcomes resistance and a weight is lifted
T
In a weight training program, decreasing recovery time between exercises increases muscular endurance
T
In dynamic exercise, a muscle contracts, shortens, and force is controlled as it moves through a range of motion
T
In isokinetic exercise, speed of muscle contraction is controlled
T
In static exercise, a muscle contracts, but does not change length, and no movement occurs
T
In variable resistance exercise, the force needed to move the weight changes to provide a maximum load throughout the range of motion
T
Individuals who should consult a physician prior to beginning a resistance-training program include those with high blood pressure, hernias, arthritis or lower back problems
T
Light hand weights are beneficial in a walking program for increasing upper body fitness
T
Loss of muscle mass with aging is primarily due to disuse
T
Moving weights through a full range of motion can enhance flexibility
T
Muscle boosts metabolism so that a person burns more calories, even while at rest
T
Muscle contraction that occurs as a muscle lengthens (as in lowering a weight) is termed eccentric contraction
T
Muscle is denser than fat and pound takes up less space, As muscle tissue is gained, if fat is lost, a person will lose inches
T
Muscles may become short and tight if exercises are performed repeatedly through a partial range of motion
T
Pilates and stability balls are popular for core strengthening
T
Principles of strength training include progressive overload, specificity and recovery
T
Prior to starting a weight training program, individuals with cardiovascular problems should check with a doctor due to the tendency for blood pressure to increase during strength training
T
Progressive overload in weight training, for strength involves increasing amount of weight lifted
T
Rate and quantity of muscle gained with strength training varies, from person to person, because they are partially genetically determined
T
Recommended frequency of resistance training is at least 2 to 3 days a week
T
Recommended number of repetitions of an exercise for general strength conditioning is at least 8 to 12 repetitions for each muscle group
T
Resistance training can decrease resting blood pressure, decrease exercise heart rate and exercise blood pressure
T
Resistance training can decrease the risk of osteoporosis
T

T
Resistance training may enhance cardiovascular health by reducing several risk factors
T
Resistance training provides emotional and psychological benefits similar to aerobic exercise

T
Strong fatigue-resistant muscle provide better balance during static and dynamic activities for people of all ages
T
Strong, flexible muscles can better withstand the stress of impact during exercise
T
The average male has about twice the muscle mass of the of the average female, which is why muscle hypertrophy in men is more pronounced
T
The progressive overload principle states that, in order to increase strength, load or repetitions must gradually be increased

The pull of muscles on bone in resistance exercise stimulates development of increased bone density
T
The pull of muscles on bone in weight-bearing exercise stimulates development of increased bone density and preserves existing bone
T
