CORRECT ANSWER GUARANTEED PASS!!
Acute Adaptations - Answer -Changes that occur in the body during and shortly after an
exercise bout
Referred to responses to exercise
Example:
Fuel substrates in muscle such as creatine phosphate (CP) can become depleted
during an exercise bout
Chronic Adaptations - Answer -Changes in the body that occur after repeated training
bouts and that persist long after a training session is over
Example:
Long term resistance training results in increases in muscle mass, which largely drives
the increase in force production
The key to inducing increases in muscle size and strength - Answer -The key to
inducing increases in muscle size and strength is to place the system under overload
Hypertrophy of muscle fibers is usually not measurable until - Answer -Hypertrophy of
muscle fibers is usually not measurable until approximately 8 to 12 weeks after the
initiation of the training program
Control of muscle force is accomplished by the interplay of two control factors: - Answer
-1. Motor Unit Recruitment
2. Rate Coding
Acute Adaptations to Resistance Training (3) NME - Answer -Neurological
~ 2 responses
Muscular
~ 6 responses
Endocrine
~ 4 responses
Acute Responses to Resistance Training - Neurological Responses (2) (EN) - Answer -
EMG amplitude - increases
Number of motor units recruited - increases
,Acute Neurological Responses to Resistance Training - General Info (4) - Answer -1.
Small muscles that require precise motor control achieve full recruitment at relatively
low percentages of maximum force output (50% of max), and after this point depend
entirely on firing rate to increase force production
2. Large muscles employ recruitment of up to 90% max or more, and firing rates tend to
be lower than for small muscles
3. Small muscles depend more heavily on firing rate to control force output while larger
muscles tend to depend more heavily on recruitment
4. As the muscle begins to fatigue, changes in recruitment and firing rate occur
Recruitment of motor units for force production follows the.......? - Answer -Recruitment
of motor units for force production follows the size principle, meaning that smaller units
are recruited at lower force levels and larger motor units are recruited at higher force
levels
During and immediately after resistance exercise.......? - Answer -During and
immediately after resistance exercise, metabolites accumulate and fuel substrates are
depleted; thus, clients need to include adequate carbohydrate in their diets
Acute Responses to Resistance Training - Muscular Changes (6) HIAACG - Answer -
Hydrogen ion concentration - increases

Ammonia levels - increases
ATP concentration - no change or slight decrease
Creatine phosphate concentration - decreases
Glycogen concentration - decreases
During and immediately after resistance exercise, metabolites accumulate and fuel
