-aka the pulmonary system Function is to bring oxygen from the environment into the lungs and remove carbon dioxide from the lungs to the outside air. Primary role is to ensure proper cellular function.
Periodization
Division of a training program into smaller, progressive stages.
Training duration
Has two prominent meanings: 1) The timeframe from the start of the workout to the finish of the workout. 2) The length of time (number of weeks) spent in one phase--or period--of training.
Proximal
Positioned nearest the center of the body, or point of reference.
Contralateral
Positioned on the opposite side of the body.
Ipsilateral
Positioned on the same side of the body.
Kinetic Chain Checkpoints
Postural assessments require observation of the human movement system. NASM uses these checkpoints to systematically view the body in an organized fashion. These refer to major joint regions of the body including the: 1) Foot and ankle 2) Knee 3) Lumbo-pelvic-hip complex (LPHC) 4) Shoulders 5) Head and cervical spine
Speed/load
Power Level method of progression used in the OPT model.
Postural distortion patterns
Predictable patterns of muscle imbalances
Radial pulse
Preferred method of recording heart rate. Located on the inside of the wrist. To find this, lightly place 2 fingers along the right side of the arm in line and just above he thumb. Once a pulse is felt, count the pulses for 60 seconds. Record the 60-second pulse rate and average over the course of 3 days. -Touch should be gentle -The test must be taken when the client is calm -All 3 tests must be taken at the same time to ensure accuracy

Isometric muscle action
When a muscle is exerting force equal to the force being placed on it, leading to no visible change in the muscle length.
Isokinetic muscle action
When a muscle shortens at a constant speed over a full range of motion. This action requires the use of expensive and sophisticated equipment that measures the amount of force generated by the muscles and adjusts the resistance (load) so that no matter how much muscular tension is produced, movement remains constant. In other words: the harder an individual pushes and pulls, the more resistance they feel.

Power Level Training
-Should only be entered after successful completion of the Stabilization and Strength Levels -Emphasizes the development of speed and power -Achieved through only one phase of training, Phase 5: Power Training -Entails the execution of a traditional strength exercise (with a heavy load) superset with a power exercise (with a light load performed as fast as possible) of similar joint dynamics -This is to enhance prime mover strength while also improving the rate of force production
Core Training Levels
-3 levels of this training within the OPT model: stabilization, strength, and power. A proper core training program follows same systematic progression. 1) Core-Stabilization -Exercises involve little motion through the spine and pelvis. These exercises are designed to improve neuromuscular efficiency and intervertebral stability, focusing on drawing-in and then bracing during the exercise. Spend about 4 weeks at this level. Examples: -Marching -Floor bridge -Floor prone cobra -Prone iso-ab 2) Core Strength -Exercises involve more dynamic eccentric and concentric movements of the spine throughout a full range of motion while clients perform the activation techniques learned in core-stabilization training (drawing-in and bracing). These exercises are designed to improve dynamic stabilization, concentric strength (force production), eccentric strength (force reduction), and neuromuscular efficiency of the entire kinetic chain. Examples: -Ball crunch -Back extensions -Reverse crunch -Cable rotations 3) Core Power -Exercises are designed to improve the rate of force production of the core musculature. This prepares client to dynamically stabilize and generate force at more functionally applicable speeds. Examples: -Rotation chest pass -Ball medicine ball (MB) pullover throw -Front MB oblique throw -Soccer throw
Strength Level Training
-Follows the successful completion of stabilization training Emphasis: Maintain stabilization endurance while increasing prime mover strength -This is the level an individual will progress to if goals are hypertrophy (increasing muscle size) or maximal strength (lifting heavy loads). Consists of 3 phases: -Phase 2: Strength Endurance Training (superset used) -Phase 3: Hypertrophy Training (optional, depends on client goals) -Phase 4: Maximum Strength Training (optional, depends on client goals)

Involves the following exercises: 1) Total Body 2) Chest 3) Back 4) Shoulders 5) Biceps 6) Triceps 7) Legs -Can also be done in a circuit style, by minimizing the rest periods between exercises. This system of training can be very beneficial for allowing maximal recovery to each body part while minimizing the amount of time wasted on rest. Ex: If it takes 1 minute to perform each exercise, by the time the client returns to chest exercise, 7 to 10 minutes could have passed, which should be sufficient time to allow for full adenosine triphosphate (ATP)/phosphocreatine (PC) recovery.
Drop-Sets
A resistance training system that is popular among bodybuilders; it is a technique that allows a client to continue a set past the point at which it would usually terminate. Considered an advanced form of resistance training suitable for experienced lifters. These involving performing a set to failure, then removing a small percentage of the load (5-20%) and continuing with the set, completing a small number of repetitions (usually 2 to 3 drops per set). A set to failure followed by three successive load decrements performed with no rest would be referred to as a triple drop.
Body Mass Index (BMI)
A rough assessment based on the concept that a person's weight should be proportional to their height. -This assessment is not designed to assess body fat, but is a quick and easy method for determining whether client's weight is appropriate for their height. -Calculated by either dividing the weight in kilograms by the square of the height in meters, OR by dividing body weight in pounds by square of height in inches and multiplying by 703. **Lowest risk for diseases lies within a range of 22 to 24.9**

Power
Ability of the neuromuscular system to produce the greatest force in the shortest time. Represented by the simple equation of force multiplied by velocity. The focus of this type of resistance-training is getting the neuromuscular system to generate force as quickly as possible (rate of force production).
Principle of specificity
According to this, the body will adapt to the level of stress placed on it and will then require more or varied amounts of stress to produce a higher level of adaptation in the future.
Resistance training principle of adaptation
Adaptation is a function of: General adaptation syndrome + Principle of specificity
Sarcopenia
Age-related loss of skeletal muscle mass. Resistance training as well as SAQ-based interventions has been found to help slow and reverse this process. -Interventions requiring increased speed of movement and rate of force production similar to those in SAQ protocols are especially effective in slowing down and reversing sarcopenia
Cardiopulmonary Exercise Testing (CPET)
Aka maximal oxygen uptake (VO2max). The most valid measurement for functional capacity of the cardiopulmonary (heart and lungs) system. -Not always practical to measure this because of equipment requirements, time involved, and willingness of clients to perform at maximal physical capacity. Therefore, submaximal tests are often the preferred method for determining the cardiorespiratory functional capacity and fitness.
FITTE principle
All exercise training recommendations, including cardio exercise, must be individually determined and should always use this principle. Stands for frequency, intensity, type, time, and enjoyment.
Arthrokinematic dysfunction

See pic for examples of this routine in different levels.
Submaximal testing
Allows for the prediction or estimation of VO2max. -Similar to VO2 tests, but they differ in that they are terminated at a predetermined heart rate intensity or time frame. -There are multiple tests of these, and are often categorized by type (run/walk tests, cycle ergometer tests, and step tests). Two common tests: YMCA 3-minute step test and the Rockport Walk Test

Calculates a client's percentage of body fat using a caliper. The four sites of skinfold measurement: -Biceps: A vertical fold on the front of the arm over the biceps muscle, halfway between the shoulder and the elbow. -Triceps: A vertical fold on the back of the upper arm, with the arm relaxed and held freely at the side. The skinfold should also be taken halfway between the shoulder and the elbow. -Subscapular: A 45-degree angle fold of 1 to 2 cm, below the inferior angle of the scapula. -Iliac crest: A 45-degree angle fold, taken just above the iliac crest and medial to the axillary line. All skinfold measurements should be taken on the right side of the body. **Consistency (in location and administration) is vital when measuring skinfolds**
Benefits of circumference measurements
Can be used on obese clients, good for comparisons and progressions, good for assessing fat patterns and distribution, inexpensive, easy to record

Closed-chain exercises
Involve movements in which the distal extremities (hands or feet) are in a constant fixed position and thus the force applied by an individual is not great enough to overcome the resistance (such as the ground or immovable object). Exercise examples: push-ups, pull-ups, squats
Open-chain exercises
Involve movements in which the distal extremities (hands or feet) are not in a fixed position and the force applied by the body is great enough to overcome the resistance (such as barbells or dumbbells). Exercise examples: bench press, lat pulldown, machine leg extension exercise
Pyramid system
Involves a progressive or regressive step approach that either increases weight with each set or decreases weight with each set. In the light-to-heavy system, client performs 10 to 12 repetitions with a light load and increases the resistance for each following set, until client can perform 1 to 2 repetitions, usually in 4 to 6 sets. The heavy-to-light system works in the opposite direction, in which client starts with a heavy load (after sufficient warm-up) for 1 to 2 repetitions, then decreases the load and increases the repetitions for 4 to 6 sets.
Split-Routine System
Involves breaking the body up into parts to be trained on separate days. Many bodybuilders and mass-dominant and strength athletes (football, shot put, etc.) use this system. Bodybuilders typically perform numerous exercises on the same day for the same body part to bring about optimal muscular hypertrophy.

Can be computed by dividing the waist measurement by the hip measurement. **A ratio greater than 0.80 for women and greater than 0.95 for men may put them at risk for a number of diseases**
Heart Rate Reserve Method
One of the two common ways to calculate THR (target heart rate). Also known as the Karvonen method; a way of establishing training intensity on the basis of the difference between a client's predicted maximal heart rate and their resting heart rate. THR=[(HRmax - HRrest) x desired intensity] + HRrest
Straight percentage method
One of the two common ways to calculate target heart rate (THR). A client's estimated maximal heart rate (HRmax) is found by subtracting their age from the number 220 (220-age). Once the client's HRmax is determined, multiply the estimated HRmax by the appropriate intensity (65-95%) at which the client should work while performing cardio exercise to calculate THR.

Horizontal loading
Performing all sets of an exercise or body part before moving on to the next exercise or body part. Involves the following exercises: 1) Total Body 2) Chest 3) Back 4) Shoulders 5) Biceps 6) Triceps 7) Legs Ex: If performing 3 sets of a chest exercise and 3 sets of a back exercise, the client would perform all 3 sets of the chest exercise before moving on to the back exercise. This is the method most commonly used in health club environments and is appropriate for maximal strength and power training when longer rest periods are required between sets. Drawback to this method: the amount of time typically spent resting, which can be more time than the actual workout itself. This system can be a metabolic progression if rest periods are monitored and limited to 30 to 90 seconds between sets. If the same muscle groups are forced to work with minimal recovery it can lead to faster development of metabolic and hypertrophy-related adaptations in the muscle.
Stabilization Level Training
Phase 1: Stabilization Endurance Training Main focus: increase muscular endurance and stability while developing optimal neuromuscular efficiency (coordination). Proprioceptively based progression: difficulty is increased by introducing a greater challenge to the balance and stabilization systems of the body (instead of simply increasing the load). -Must be done before strength and power training -Stabilization Endurance Training not only addresses the existing structural deficiencies but also provides a superior way to alter body composition (reduce body fat) because all exercises are typically performed in a circuit fashion (short rest periods) with a high number of reps. Body forced to recruit more muscles to stabilize itself-->more calories expended

Purpose: This transitional movement assessment also assesses dynamic flexibility, core strength, balance, and overall neuromuscular control. A reliable and valid measure of lower extremity movement patterns. Knee valgus has shown to be influenced by decreased hip abductor and hip external rotation strength, increased hip adductor activity, and restricted ankle dorsiflexion. This suggests that movement impairments observed during the transitional movement assessment may be the result of alterations in available joint motion, muscle activation, and overall neuromuscular control. Procedure: Client stands with hands on the hips, eyes focused on an object straight ahead. Foot pointed straight ahead. The foot, ankle, knee, and the lumbo-pelvic-hip complex in a neutral position. Movement: 1) Have client squat to a comfortable level and return to starting position. 2) Perform up to 5 reps before switching sides. Views: View the knee from the front. Knee should track in line with the foot (2nd and 3rd toes). Compensation: Does the knee move inward (adduct and internally rotate)? Record findings, then refer to Table on pg 146 to determine overactive and underactive muscles.

Used for clients looking to improve athletic performance. These measure upper extremity stability and muscular endurance, lower extremity agility, and overall strength. -Push-Up Test -Davies Test -Shark Skill Test -Bench Press Strength Assessment -Squat Strength Assessment
Vasodilators
Used in the treatment of hypertension and congestive heart failure.
Antidepressants
Used in the treatment of various psychiatric and emotional disorders.
Functional flexibility
Uses self myofascial release and dynamic stretching. Phase 5 of opt Dynamic stretching requires integrated, multiplanar soft tissue extensibility, with optimal neuromuscular control, through the full range of motion, or essentially movement without compensations. Appropriate at the power level (phase 5) of the OPT model or before athletic competition.
Dynamic stretching
Uses the force production of a muscle and the body's momentum to take a joint through the full range of motion. Mechanism of action: -Reciprocal inhibition Acute variables: -1-2 sets -10-15 reps -3-10 exercises Examples: -hip swings -medicine ball rotations -walking lunges -prisoner squats -multiplanar lunges -single-leg squat touchdowns -tube walking -medicine ball lift and chop
Superset System
Uses two exercises performed in rapid succession of one another. There are multiple variations of this system. Popular among bodybuilders and may be beneficial for muscular hypertrophy and muscular endurance. The first variation: -Perform two exercises for the same muscle group back to back Ex: Perform the bench press exercise immediately followed by push-ups to fatigue the chest musculature. This improves muscular endurance and hypertrophy because the volume of work is relatively high. This variation can use two, three (a tri-set), or more exercises (a giant set) for the target muscle group. The second variation: -Perform two exercises back to back that involves antagonist muscle groups (e.g. chest and back or quadriceps and hamstring complex). Performing in this manner allows a significant load to be placed on the target muscle during each set. This is possible because the agonist is working, the antagonist is recovering, and vice-versa. This system typically involves sets of 8 to 12 repetitions with no rest between sets or exercises; however, any number of repetitions can be used.
Arteries
Vessels that transport blood away from the heart.
Veins
Vessels that transport blood from the capillaries toward the heart.
Balance
When the body is in equilibrium and stationary, meaning no linear or angular movement.
Pulse points
Where arteries come close enough to the skin to be able to have a pulse (heart rate) felt. There are 7 of these.
The core
Where the body's center of gravity (COG) is located and where all movement originates. Composed of the structures that make up the lumbo-pelvic-hip complex (LPHC), including the lumbar spine, the pelvic girdle, abdomen, and hip joint.
Target Heart Rate Training Zones
Zone one: Builds aerobic base and aids in recovery Zone two: Increases aerobic and anaerobic endurance Zone three: Builds high-end work capacity
Principle of specificity
aka Specific Adaptation to Imposed Demands (SAID principle) Principle that states the body will adapt to the specific demands placed on it. Ex: If Jeff repeatedly lifts heavy weights, Jeff will produce higher levels of maximal strength. If Tina repeatedly lifts lighter weights for many repetitions, Tina will develop higher levels of muscular endurance.
negative energy balance
aka caloric deficit During this, amino acids are used to assist in energy production (or gluconeogenesis), wherein protein requirements may dramatically increase.
Blood pressure
the pressure of the circulating blood against the walls of the blood vessels after blood is ejected from the heart. There are 2 parts to measuring this.
Acceptable systolic blood pressure
≤120 millimetres (mm) of mercury (Hg) or mm Hg.
Acceptable diastolic blood pressure
≤80 mm HG
