Determinants and Correlates that Affect Tension Generation of
Skeletal Muscl
Factor
Cross-section and size of the muscle (includes muscle
fiber number and size)
Fiber arrangement and fiber length (also relates to cross-sectional
diameter of the muscle)
Fiber-type distribution of muscle: type I (tonic, slow-twitch) and type
IIA & IIB (phasic, fast-twitch)
Length-tension relationship of muscle at time of
contraction
Recruitment of motor units
Frequency of firing of motor units
Type of muscle contraction
Speed of muscle contraction (force-velocity relationship)
Influence
The larger the muscle diameter, the greater its tension-producing
capacity
Short fibers with pinnate and multipinnate design in high force
producing muscles (ex. quadriceps, gastrocnemius, deltoid, biceps
brachii)
Long parallel design in muscles with high rate of shortening but less
force production (ex. sartorius, lumbricals)
High percentage of type I fibers: low force production, slow rate of
maximum force development, resistant to fatigue
High percentage of type IIA and IIB fibers: rapid high forceproduction;
rapid fatigue
Muscle produces greatest tension when it is near or at
thephysiological resting position at the time of contraction
The greater the number and synchronization of motor unitsfiring, the
greater the force production
The higher the frequency of firing, the greater the tension
Force output from greatest to least: eccentric, isometric,concentric
muscle contraction
Concentric contraction: ↑ speed → ↓ tension. Eccentric contraction:
↑ speed → ↑ tension

Infancy, Early Childhood, and Preadolescence
• At birth, muscle accounts for about 25% of body weight.
• Total number of muscle fibers is established prior to or early during infancy.
• Postnatal changes in distribution of type I and type II fibers in muscle are relatively complete by the end of the first year
of life.
• Muscle fiber size and muscle mass increase linearly from infancy to puberty.
• Muscle strength and muscle endurance increase linearly with chronological age in boys and girls throughout child-hood
until puberty.
• Muscle mass (absolute and relative) and muscle strength is just slightly greater (approximately 10%) in boys than girls
from early childhood to puberty.
• Training-induced strength gains occur equally in both sexes during childhood without evidence of hypertrophy until
puberty.
Puberty
• Rapid acceleration in muscle fiber size and muscle mass, especially in boys. During puberty, muscle mass increases more
than 30% per year.
• Rapid increase in muscle strength in both sexes.
• Marked difference in strength levels develops in boys and girls.
• In boys, muscle mass and body height and weight peak before muscle strength; in girls, strength peaks before body weight.
• Relative strength gains as the result of resistance training are comparable between the sexes, with significantly greater
muscle hypertrophy in boys.
Young and Middle Adulthood
• Muscle mass peaks in women between 16 and 20 years of
age; muscle mass in men peaks between 18 and 25 years of age.
• Decreases in muscle mass occur as early as 25 years of age.
• Muscle mass constitutes approximately 40% of total body weight during early adulthood, with men having slightly more
muscle mass than women.
• Strength continues to develop into the second decade, especially in men.
• Muscle strength and endurance reach a peak during the second decade, earlier for women than men.
• By sometime in the third decade, strength declines between 8% and 10% per decade through the fifth or sixth decade.
• Strength and muscle endurance deteriorate less rapidly in physically active versus sedentary adults.
• Improvements in strength and endurance are possible with only a modest increase in physical activity.
Late Adulthood
• Rate of decline of muscle strength accelerates to 15% to 20% per decade during the sixth and seventh decades and
increases to 30% per decade thereafter.
• Loss of muscle mass continues; by the eighth decade, skeletal muscle mass has decreased by 50% compared to peak muscle
mass during young adulthood.
• Muscle fiber size (cross-sectional area), type I and type II fiber numbers, and the number of alpha motoneurons all
decrease. Preferential atrophy of type II muscle fibers occurs.
• Decrease in the speed of muscle contractions and peak power.
• Gradual but progressive decrease in endurance and maximum oxygen uptake.
• Loss of flexibility reduces the force-producing capacity of muscle.
• Minimal decline in performance of functional skills during the sixth decade.
• Significant deterioration in functional abilities by the eighth decade associated with a decline in muscular endurance.
• With a resistance training program, a significant improvement in muscle strength, power, and endurance is possible during
late adulthood.
• Evidence of the impact of resistance training on the level of performance of functional motor skills is mixed but promising.

during an exercise session
• Frequency: the number of exercise sessions per day or perweek
• Rest interval: time allotted for recuperation between sets and sessions of
exercise

 the
amount of resistance (weight) imposed
on the contracting muscle during each
repetition of an exercise.
 Submaximal loading. Exercise at moderate to
low intensities
 Near maximal or maximal loading. Highintensity exercise
 Repetition
Maximum : the greatest amount of
weight (load) a muscle can move through the
available range of motion (ROM) a specific number
of times.
 1 RM (the greatest amount of weight a subject can
lift through the available ROM just one time) as the
baseline measurement of a subject’s maximum
effort
 it is a frequently used, safe and reliable
measurement tool method for healthy young adults
and athletes as well as active older adults prior to
beginning conditioning programs.
Use
of a 1 RM as a baseline
measurement of dynamic strength is
inappropriate for some patient
populations because it requires one
maximum effort. It is not safe for
patients, for example, with joint
impairments, patients who are
recovering from or who are at risk for
soft tissue injury, or patients with
known or at risk for osteoporosis or
cardiovascular pathology.

Zone: low (30% to 40%) for
sedentary, untrained individuals or very high
(80% to 95%) for Those already highly
trained. For healthy but untrained adults, a
typical training zone usually falls between
60% and 70% of an RM. The lower percentage
of this range is safer at the beginning of a
program to enable an individual to focus on
learning exercise form and technique.
 Volume: Repetitions and Sets To Improve
Muscle Strength? OR To Improve Muscle
Endurance?
DeLorme’s
early studies three sets of a
10 RM performed for 10 repetitions over
the training period led to gains in
strength. Current recommendations are
to use an exercise load that causes
fatigue after 6 to 12 repetitions for two
to three sets (6 to 12 RM). When fatigue
nolonger occurs after the target number
of repetitions has been completed, the
level of resistance is increased to once
again overload the muscle.
 Training
to improve local endurance involves
performing many repetitions of an exercise
against a submaximal load, the load can be
increased slightly.
 Endurance training can also be accomplished
by maintaining an isometric muscle
contraction for incrementally longer periods
of time.
in
a single session, as is often the
case in rehabilitation or conditioning
programs, large muscle groups should
be exercised before small muscle
groups and multijoint muscles before
single-joint muscles.
In addition, after an appropriate
warm-up, higher intensity exercises
should be performed before lower
intensity exercises.
Initially
in an exercise program, so long
as the intensity and number of
repetitions are low, short sessions of
exercises sometimes can be performed
on a daily basis several times per day.
This frequency is often indicated for
early postsurgical patients when the
operated limb is immobilized and the
extent of exercise is limited to lowintensity isometric (setting) exercises to
prevent or minimize atrophy.
 As
the intensity and volume of exercise
increases, every other day or up to five
exercise sessions per week is common.
 Frequency is again reduced for a maintenance
program, usually to two times per week. With
prepubescent children and the very elderly,
frequency is usually limited to two to three
sessions per week.
 Highly trained athletes involved in body
building, power lifting, and weight lifting who
know their own response to exercise often
train at a high intensity and volume up to 6
days per week.
the
total number of weeks or months
during which a resistance exercise
program is carried out.
strength gains, observed early in a
resistance training program (after 2 to 3
weeks) are the result of neural
adaptation. For signiifi-cant changes to
occur in muscle, such as hypertrophy or
increased vascularization, at least 6 to 12
weeks of resistance training is required.
Purpose
of Rest Intervals: necessary to
allow time for the body to recuperate
from the acute effects of exercise
associated with muscle fatigue or to
offset adverse responses, such as
exercise induced, delayed-onset muscle
soreness.
Only with an appropriate balance of
progressive loading and adequate rest
intervals can muscle performance
improve.
 In
general, the higher the intensity of exercise the
longer the rest interval. For moderate-intensity
resistance training, a 2- to 3-minute rest period after
each set is recommended.
 A shorter rest interval is adequate after low-intensity
exercise; longer rest intervals (4 to 5 minutes) are
appropriate with high-intensity resistance training,
particularly when exercising large, multijoint muscles,
such as the hamstrings, which tend to fatigue rapidly.
 Patients
with pathological conditions that make
them more susceptible to fatigue, as well as
children and the elderly, should rest at least 3
minutes between sets by performing an unresisted
exercise, such as low intensity cycling, or
performing the same exercise with the opposite
extremity.
 Rest between exercise sessions must also be
considered. When strength training is initiated at
moderate intensities (typically in the intermediate
phase of a rehabilitation program after soft tissue
injury) a 48-hour rest interval between exercise
sessions (that is, training every other day) allows
the patient adequate time for recovery.
the
type of muscle contraction that
occurs, and the manner in which the
exercise is carried out. For example, a
patient may perform an exercise
dynamically or statically or in a weightbearing or non-weight-bearing position.
Mode of exercise also encompasses the
form of resistance, that is, how the
exercise load is applied. Resistance can
be applied manually or mechanically.
 Type
of Muscle Contraction: dynamic concentric,
isometric, dynamic eccentric
 Position for Exercise: Weight-Bearing or NonWeight-Bearing
 Forms of Resistance: Manual resistance and
mechanical resistance, A constant or variable load,

and psychological staleness prior to competition
and to optimize performance during competition.
