Muscle Identification The human body consists of many muscles and muscle groups. We will focus on a select few that are most prevalent when training.

2 Muscle Identification The human body consists of many muscles and muscle groups. We will focus on a select few that are most prevalent when training. The muscular system is designed to maintain body posture, move joints and limbs, and provide protection for the internal systems. Please take a look at the diagram below to become familiar with the location of these muscles. It is important to understand where each muscle is located and which exercises will help strengthen the specific muscle or muscle group. The diagram below lists the muscle using its scientific name. Understand common terms and also the scientific name for the muscle. For example, we commonly refer to the bench press working our chest muscles, however, this is scientifically named our pectoral group. Source: **Keep in mind that the quadriceps and hamstring muscles are classified as a group of smaller muscles. We will focus on calling them the quadriceps and hamstring group in class.

3 The body consists of many, many smaller muscles. As we continue learning about various concepts, these muscles may be referred to as joint action muscles ex. wrist flexors. With the large amount of muscle names, there is no way to expect anyone to remember all of them, well, unless you are a doctor. Focus your attention of the major muscle groups primarily the ones we tend to focus on in class. We rarely refer to an exercise working the gluteus minimum, but rather the gluteal group. More information can be found at including a more in-depth look at certain muscles and locations, as well as their specific actions. I recommend exploring this site to learn more.

4 Movement Terminology This section focuses on specific movements that occur at the joints in the body. A joint is the location where bones meet. The bones are connected by ligaments and tendons. The tendons connect the bone to a specific muscle which allows movement in the joint. As a muscle contracts, the joint will move in a specific pattern. We will focus solely on the terminology used to describe each specific movement at this point in time. Eventually, you will understand which muscles and muscle groups control the specific movement at each joint. Terminology: Flexion Decrease in joint angle Extension Increase in joint angle Abduction Movement away from the center line of the body Adduction Movement towards the center line of the body **Center line = imaginary line that runs from the top of the head down through the middle of the body through the ground. Horizontal Flexion Decrease in joint angle across the front of the body Horizontal Extension Increase in joint angle away from the front of the body Rotation Turning about a joint s axis **External (Lateral) Rotation, Internal (Medial) Rotation, Pronation, Supination, Circumduction Special Cases of Movement: In addition to those movements above, certain joints are capable of moving in other ways. Below are some examples: Joint Actions at the Ankle: Plantar Flexion: Pointing the toes downward or below heal Dorsiflexion: Pointing the toes upward or above heal Eversion: The sole of the foot turns outward Inversion: The sole of the foot turns inward Joint Actions at the Hip/Neck: Lateral Flexion: Bending sideways Joint Actions at the Shoulder Girdle (shoulder blades): Protraction: Moving shoulders forward Retraction: Moving shoulders backward Elevation: Moving shoulders upward Depression: Moving shoulders downward For pictures and more information check out Assessment: Movement Terminology

5 Muscular Contractions and Conditioning Muscle contraction occurs when a muscle or group of muscles change size. Muscles change size when a load is placed upon them in addition to a joint moving. The muscle contraction causes the joint to move. In other words, in order for the body to move in any way (think back to movement terminology) the muscle that crosses that joint must contract. There are 3 common forms of contractions responsible for joint actions. 1. Concentric contraction occurs when there is tension causing the muscle to shorten. Ex. The positive part of the exercise when the muscle pushes/pulls the action. This normally causes the extra muscle soreness associated with strength training. 2. Eccentric contraction occurs when there is tension but the muscle lengthens. Ex. The negative part of the exercise when the muscle controls the action. 3. Isometric contraction occurs when there is tension in the muscle but the joint does not move. Ex. The sticking point of an exercise OR when an exercise is held at a certain spot away from the top/bottom of the exercise. An overall example can be found using the biceps curl: 1. The upward phase (raising load to shoulder) would be caused by a concentric contraction by the biceps/arm flexors during the positive part of the exercise. 2. The downward phase (lowering load to starting position) would be controlled by an eccentric contraction by the biceps/arm flexors during the negative part of the exercise. 3. If the load was held at a parallel level to the floor (middle of exercise), this would be an isometric contraction. Understanding when and how each type of contraction is used will help you increase your training regimen. Combining High Intensity Training (HIT) with the idea of muscular contraction will allow for a better understanding of training principles. The concentric phase should be very fast and explosive while the eccentric phase should be slow and controlled to continue working the primary muscle group(s). As you know by now, your body consists of many muscles and muscle groups. Muscle groups work together to provide a force to allow your body to move. Training these muscle groups in specific ways makes each movement occur much easier and with more purpose. Not only can you train muscles with a specific action or motion at various joints, but you can train the muscle or muscle group itself with a specific duration. We will call this muscular conditioning. Training muscle groups consist of multiple ways of conditioning. The most common forms of muscular conditioning are training for power, muscular strength, and muscular endurance. Each form is trained using a different range of resistance and a different range of repetitions. See below for an easy reference: Type Resistance/Load Repetitions (Reps) Repetition Speed Muscular Power Heavy Low 5 reps and fewer Fast Muscular Strength Moderate High 6 8 reps Moderate - Slow Muscular Endurance Comparatively Light High 10+ reps Moderate - Slow

6 Muscular power involves moving a heavy load as fast as possible a small number of times. A 1RM would be a great example of demonstrating muscular power or overall total strength at that area of the body. Muscular strength is considered how much load your muscles can move over a short period of time. Muscular endurance is how long your muscles are able to work. Certain muscle groups are designed to handle increased loads, therefore, can be trained using the power phase. Other muscle groups are designed to handle lower resistances but can perform for longer periods of time, meaning muscular endurance is a more suited type of training. The workouts you perform in class are designed to target each muscle group in the way it was intended to work to maximize your body s potential.

Please write a reflection about this period of time and how you feel. Your reflection should include the following: 1. How you felt at the beginning of the term about the upcoming training. 2. Describe the various aspects of training you learned about and how you incorporated them into your workouts. 3. Explain the gains you made in regards to the many benefits of training (muscular endurance/strength/power, flexibility, body composition, attitude, self-esteem, etc.). 4. Discuss if you have accomplished the goals you wanted to reach over the last term. If you were able to reach them, what helped your success? If not, what you can do in the future to be successful? 5. Explain the goals you want to accomplish as you move forward with your training. This should be an HONEST reflection. Make sure to write in a complete and thoughtful manner.
