Muscle Types
Skeletal: attached to the bones by
connective tissue called “tendons”. This type causes voluntary contractions and
is the target muscle type of strength training.
Smooth: produces movement in your
internal organs.
Cardiac: heart muscle causes the
rythmucal contractions of the heart.
Fast Twitch Muscle Fiber: skeletal muscle, white
muscle fibers, contract quickly, easy to fatigue, and are responsible for the
explosive muscle contractions. These fibers are used for anaerobic activities.
Slow Twitch Muscle Fiber: skeletal muscle, red muscle
fiber, contract slowly, does not fatigue easily, & has a large blood
supply. These allow us to do endurance, or aerobic, activity.

Muscular
Contraction Types
Concentric Muscle Contraction: Muscle action in which the
muscle is shortening under its own power. This action is commonly called
"positive" work, or, redundantly, "concentric contraction."
Eccentric Muscular Contraction: Muscle action in which the
muscle resists while it is forced to lengthen. This action is commonly called
"negative" work, or "eccentric contraction," but, since the
muscle is lengthening, the word "contraction" is misapplied.
Isometric Muscular Contraction:
Muscle action in which the
muscle attempts to contract against a fixed limit. This is also sometimes
called "isometric contraction," although there is not appreciable
shortening of the muscle.
Identify
The Type Of Contraction (C, E, or I)

to the chest on the lat pulldown. _______
4)
Agonist &
Antagonist
Agonist: the prime mover in a given
exercise.
The agonist when doing a leg
curl is the ____________ muscle.
Antagonist: The muscle that makes the
opposite movement from the prime mover. Asissts in joint stabilization and
break of momentum at the end of a fast motion.
The antagonist when doing a
bicep curl is the __________ muscle.
5)
Atrophy &
Hypertrophy
Atrophy: decrease in size of the
muscle. A muscle will atrophy when demands on the muscle are decreased, or
ceased all together. The less work the smaller the muscle.
Hypertrophy: increase in size of the
muscle. Hypertrophy results from enlargement of muscle fibers. Hypertrophy will
occur when a sufficient overload is placed upon the muscle to force it to work
harder than normal and grow, or adapt. (Increased
muscle mass will result in your body burning more calories because muscles use
calroies for fuel 24 hours a day.)
6)
Muscular Soreness
Acute Muscle Soreness: the pain one experiences
during or immediately after exercise. This caused by a build up of lactic acid
in the muscle tissue or shifts in fluid balance in the muscle cells.
DOMS: (Delayed Onset Muscle
Soreness) pain experienced one to days after exercise. This type of soreness is
most likely caused by microscopic tears in the muscle itself.
Part III: Fitness Concepts
1) Principle of Progression/Over Load
The principle of overload states that a greater than normal stress or
load on the body is required for training adaptation to take place. The body
will adapt to this stimulus. Once the body has adapted to the stress, then a
different stimulus is required to continue the change. In
order for a muscle (including the heart) to increase strength, it must be
gradually stressed by working against a load greater than what it has adapted.
List an example of
overload.
The principle that the body adapts very specifically to the training
stimuli it is required to deal with. The body will perform best at the specific
speed, type of contraction, muscle-group usage and energy source usage it has
become accustomed to in training. In order to improve your strength,
endurance and fitness, you have to progressively increase the frequency,
intensity and time of your workouts. The Specificity
Principle simply states that for these reasons, training must go from highly
general training to highly specific training. For example, if you
are a sprinter, you may start out with easy running and general strength
training before moving on to explosive training in the way of plyometrics or
sprinting out of the blocks. If you try to do explosive, high intensity
training too soon, you will run the risk of such training being ineffective and
possibly resulting in injury. The principle of
Specificity also implies that to become better at a particular exercise or
skill, you must perform that exercise or skill. Your strength
training exercises should try to emulate the same movements that you intend to
perform during competition/sport/activity.
Name a sport & choose an exercise that
is specifcally related to that sport & why it can help.
3) Variation in Exercise
Variation in your exercise routine is very important to keep you moving
towards your fitness goal, to keep you from hitting a fitness plateau. Because
your body adapts quickly to the stress that is applied to your body, you need
to change your workout routine every 4 to 6 weeks. Variation in your
workout can occur in several ways:
List 4 variations of the bench
press done in class.
4) Multiple Joint Vs Single Joint Exercises
Multi- joint exercises employ the use of
more than one joint for a given
exercise, therefore employing the use of more
than one muscle group. Multi- joint exercises work more muscle groups than
single- joint & should be completed first in the workout.
Single joint exercises tend to stress the smaller muscle groups. These should be worked last so they do not hinder the smaller muscles ability to work with larger groups during multi- joint lifts. This will result in a lowered incidence of injury.
List examples of multi- joint lifts
List examples of single joint lifts
5) F.I.T. Concept
Frequency: How often do you exercise
per week? (exercise sessions per week)
Aerobic activities must be performed at least three times per week to
reach an adequate level of cardiovascular fitness. Strength training must be
performed a minimum of 2-3 times a week to build up adequate strength
levels.
Intensity: How hard is your exercise
session? (Level of intensity)
To obtain the greatest cardiovascular benefit, the American College of Sports
Medicine recommends that the intensity of your training be sufficient to
increase your heart rate to a range of 60% to 90% of your maximum heart
rate. This is your target heart rate zone. To find your target
heart rate zone:
220 - (minus your age) x .90 = Upper limit of your target heart rate zone
220 - (minus your age) x .60 = Lower limit of your target heart rate zone.
For strength training one needs to exercise at 50- 95% of their 1
repitition max in order to receive benefits. However, in order to maximize
these gains one should begin with high reps and a low intensity. You should
gradually decrease the amount of reps you perform and increase the intensity.
This is called periodization. Periods, or cycles, should last between 8-
12 weeks in length.
Time: How long do you
exercise? (Duration of the exercise
session)
To achieve all the values of cardiovasculur training, you must maintain the
target heart rate (60% - 90%) for a minimum of 20 minutes. As you
become more fit, you should increase the your time in the target heart rate
zone to gain a higher level of fitness. However the intensity level may
need to be reduced or lowered, in order for your body to accommodate or handle
the stress from the increase in time.
For strength training workout sessions should last no more than 1 ½
hours. Any longer than this and overtraining may occur.
Part V: Flexibility Concepts
2) Types of Stretching
Active: An active stretch is one where you assume a
position and then hold it there with no assistance other than using the
strength of your agonist muscles. For example, bringing your leg up high and
then holding it there without anything (other than your leg muscles themselves)
to keep the leg in that extended position.
Passive: A passive stretch is one
where you assume a position and hold it with some other part of your body, or
with the assistance of a partner or some other apparatus. For example, bringing
your leg up high and then holding it there with your hand.
Ballistic: Ballistic stretching uses
the momentum of a moving body or a limb in an attempt to force it beyond its
normal range of motion. This is stretching, or "warming up", by
bouncing into (or out of) a stretched position, using the stretched muscles as
a spring which pulls you out of the stretched position. (e.g. bouncing down
repeatedly to touch your toes.) This type of stretching is not considered
useful and can lead to injury.
PNF: PNF is an acronym for proprioceptive neuromuscular facilitation. PNF refers
to any of several post-isometric relaxation
stretching techniques in which a muscle group is passively stretched, then
contracts isometrically against resistance while in the stretched position, and
then is passively stretched again through the resulting increased range of
motion. PNF stretching usually employs the use of a partner to provide
resistance against the isometric contraction.
Dynamic: Dynamic stretching,
according to Kurz, "involves
moving parts of your body and gradually increasing reach, speed of movement, or
both." Do not confuse dynamic stretching with ballistic stretching!
Dynamic stretching consists of controlled leg and arm swings that take you
(gently!) to the limits of your range of motion. In dynamic stretches, there
are no bounces or "jerky" movements. An example of dynamic stretching
would be slow, controlled leg swings, arm swings, or torso twists.
List one example each of a passive, dynamic,
& PNF stretch.
Part V: Warming Up & Cooling Down
1) Benefits of proper warm-up and cool down
Warming up brings about important physiological
changes that reduce the risk of injury, while also preparing the body for
higher levels of effort and energy utilization.
Specifically...a gradual warm-up:
Blood tends to accumulate in the lower body when a
vigorous exercise session is stopped abruptly. With reduced blood return,
cardiac output decreases and lightheadedness may occur. Because muscle movement
helps squeeze blood back to the heart, it is important to continue lower level
physical activity after the exercise session is completed (i.e. the cool-down
period).
The best activities for both are simply to work at a
much lower pace in an aerobic/cardiovascular activity that you are using for
training. Examples include slow cycling on a bike or walking on a treadmill. As
a general guideline, a 5 – 10 minute session should be dedicated for both
warming-up and cooling-down.
Design a 6 exercise cool down for your needs.
Part VII: Rest & Recovery
Consecutive days of hard resistance training for the same muscle group
can be detrimental. The muscles must be allowed sufficient recovery time to
adapt. Strength training can be done every day only if the exercised muscle
groups are rotated, so that the same muscle or muscle group is not exercised on
consecutive days. There should be at least a 48-hour
recovery period between workouts for the same muscle groups. For
example, the legs can be trained with weights on Monday, Wednesday, and Friday
and the upper body muscles on Tuesday, Thursday, and Saturday.
Recovery is also important within a workout. The recovery time between
different exercises and sets depends, in part, on the intensity of the workout.
Rest Between Sets
Conditioning Cycle: 30sec to 1min.
Hypertrophy Cycle: 1 to 1 ½ min.
Strength Cycle: 2 to 2 ½ min.
Power Cycle: 2 ½ to 3 min.
Peak Cycle: 3 to 4 min.

KEY MESSAGES
FACTS
AEROBIC - Using oxygen.
ANAEROBIC - Not using oxygen.
ANAEROBIC ACTIVITIES - Activities using muscle groups at high intensities that exceed the body’s capacity to use oxygen to supply energy and create and oxygen debt by using energy produced without oxygen.
ANTAGONIST - A muscle that can provide an opposing action to the action of another muscle (the agonist) around a joint.
ATROPHY - Reduction in size, or wasting away, of a body part, organ, tissue or cell.
BALLISTIC MOVEMENT - An exercise movement in which a part of the body is “thrown” against the resistance of antagonist muscles or against the limits of a joint. The latter, especially, is considered dangerous to the integrity of ligaments and tendons.
CARDIOVASCULAR - Pertaining to the heart and blood vessels.
CIRCUIT TRAINING - A series of exercises, performed one after the other, with little rest between. Resistance training in this manner increases strength while making some contribution to cardiovascular endurance as well. (It remains controversial as to whether a significant cardiovascular benefit will be achieved in the absence of very consistent motivation or close supervision of the sessions.)
CONCENTRIC ACTION - Muscle action in which the muscle is shortening under its own power. This action is commonly called “positive” work, or, redundantly, “concentric contraction.”
COOL DOWN - A gradual reduction of the intensity of exercise to allow physiological processes to return to normal. Helps avoid blood pooling in the legs and may reduce muscular soreness.
DURATION - The time spent in a single exercise session. Duration, along with frequency and intensity, are factors affection the effectiveness of exercise.
ECCENTRIC ACTION - Muscle action in which the muscle resists while it is forced to lengthen. This action is commonly called “negative” work, or “eccentric contraction,” but, since the muscle is lengthening, the word “contraction” is misapplied.
EXERCISE PRESCRIPTION - A recommendation for a course of exercise to meet desirable individual objectives for fitness. Includes activity types; duration, intensity, and frequency of exercise.
PLYOMETRIC - A type of exercise that suddenly preloads and forces the stretching of a muscle an instant prior to its concentric action.
SPECIFICITY - The principle that the body adapts very specifically to the training stimuli it is required to deal with. The body will perform best at the specific speed, type of contraction, muscle-group usage and energy source usage it has become accustomed to in training.
STRENGTH - The amount of muscular force that can be exerted.
STRETCHING - Lengthening a muscle to its maximum extension; moving a joint to the limits of extension.
TARGET HEART RATE (THR) - The heart rate at which one aims to exercise.
TENDON - The fibrous connective tissue that connects muscle to bone.
WARM-UP - A gradual increase in the intensity of exercise to allow physiological processes to prepare for greater energy outputs.
