Thera Ex Continuation Flashcards
A patient’s health status, diet, or lifestyle (sedentary or active) all influence _______.
Fatigue Threshold
The influence that the fatigue threshold affects.
A patients health status, diet and lifestyle
Adequate time for fatiguing exercise must be built into every resistance exercise program. The body must be given time to restore itself to a state where the force capacity returns to 90-95% of the pre-exercise capacity.
Recovery from Exercise
Muscle performance capability will change across the lifespan
Age
=>At birth, muscle accounts for about 25% of body weight
=> Total number of muscle fibers is established before birth or early in infancy
=> Muscle fiber size and muscle mass increase linearly from infancy to puberty
Infancy, Childhood, and Preadolescence
=> Rapid acceleration in muscle fiber size and muscle mass, especially in boys. During puberty, muscle mass increase by more than 30% per year.
=> Rapid increase in muscle strength in both sexes
=> Marked difference in strength levels develops between boys and girl
Adolescence
=>Muscle mass peaks in women between 16 and 20 years of age; muscle mass in men peaks between 18 and 25.
=> Muscles mass constitutes approximates 40% of total body weight
=> Muscle continues to develop into the second decade, especially in men.
Young and middle adulthood
=> Muscle contraction speed and peak power production both decrease
=> Endurance and maximum oxygen uptake gradually but progressively decrease
=> The force-producing capacity of muscle is reduced
Late adulthood
An array _____ can influence muscle performance and how easily, vigorously, or cautiously a person moves. Just as injury and disease adversely affect muscle performance, so can a person’s mental health status.
Psychological Factors and Cognitive Factors
A patient must be able to focus on a given task to learn how to perform it correctly.
Attention
Involves the ability to process relevant data while screening out irrelevant information from the environment and to responds to internal cues from the body,
Attention
If a resistance exercise program is to be effective, a patient must be willing to put forth and maintain sufficient effort and adhere to the program over time. Also, meaningful activities are perceived as having potential usefulness or periodically modifying an exercise routine to help maintain a patient’s interest in resistance training.
Motivation and Feedback
Physiological Adaptation to Resistance Exercise
Skeletal Muscle structure
Neural System
Metabolic System and enzymatic activity

Connective Tissue
Training-induced adaptations to resistance exercise, known as
Chronic physiological Responses
It is well accepted that the initial, rapid gain in the tension-generating capacity of skeletal muscle from a resistance training program is mainly attributed to neural responses.
Neural Adaptations.
It is an increase in the size of an individual muscle fiber caused by increased myofibrillar volume.
Hypertrophy of Skeletal Muscle Adaptations
- Hypertrophy of skeletal muscle appears to result from increased ______.
- What type of muscle fibers appear to increase in Hypertrophy?
- Protein (Actin and Myosin)
- Type 2B
This caused a portion of the increase in muscle size that occurs with heavy resistance training, which increases muscle fibers.
Hyperplasia
Essential elements of manual muscle testing and dynamometry
Alignment and Stabilization
Compensatory movement patterns are caused by the muscle action of a more potent adjacent agonist or a muscle group that normally serves as a stabilizer.
Substitute Motion
Proper alignment is determined by considering the fiber orientation, the line of pull, and the specific action desired of the muscle to be strengthened
Alignment and Muscle Action
The patient or limb should be positioned in a way that considers how both gravity and a weight provide external resistance to the muscle being stretched
Alignment and Gravity
Refers to holding down a body segment or holding the body steady
Stabilization
