24
Horizontal Adduction
Movement of the arm or thigh in the transverse plane from a lateral position to an anterior position.
25
Scapular Retraction
Adduction of scapula; shoulder blades move toward the midline.
26
Scapular Protraction
Abduction of scapula; shoulder blades move away from the midline.
27
Scapular Depression
Downward (inferior) motion of the scapula.
28
Scapular Elevation
Upward (superior) motion of the scapula.
29
``` iso = ? tonic = ? metric = ? kinetic = ? ```
``` iso = same/equal tonic = tension metric = length kinetic = motion ```
30
Isotonic
Force is produced, muscle tension is developed, and movement occurs through a given range of motion. - eccentric vs concentric
31
Eccentric Muscle Action
Occurs when a muscle develops tension while lengthening; deceleration.
32
Concentric Muscle Action
When a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle; acceleration.
33
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; pausing.
34
Isokinetic Muscle Action
When a muscle shortens at a constant speed over the full range of motion.
35
Components of a Fitness Assessment
1) Subjective Info (pre-participation health screening (PAR-Q,) general health history, medical history, and lifestyle). 2) Objective Info (physiologic assessments, body composition testing, cardiorespiratory assessments, static & dynamic postural assessments, and performance assessments).
36
Preparticipation Health Screening from PARQ - low, moderate, high risk
low risk - no major signs or symptoms of disease; 1 or less cardiovascular disease risk factors moderate risk - no signs or symptoms of disease; 2 or more cardiovascular disease risk factors high risk - one or more signs or symptoms of cardiovascular, pulmonary, or metabolic disease.
37
Pulse
Created by blood moving or pulsating through arteries each time the heart contracts. - preferred measurement on the inside of the wrist - most accurate when rising in the morning - gentle touch taken same time each day - normal is between 70-80 bpm
38
Heart Rate Range
Zone 1: 65% to 75%, builds aerobic & aids in recovery Zone 2: 76% to 85%, increases aerobic & anaerobic endurance Zone 3: 86% to 95%, builds high-end work capacity
39
Maximum HR method
Straight Percentage method: 220 - age = max HR (220 - age) x HR range
40
HR Reserve (HHR) method
Karvonen formula: | THR = [(HRmax - HRrest) x desired intensity] + HRrest
41
Systolic BP
- top number - pressure within the arteries after the heart contracts - first sound of the heart beat
42
Diastolic BP
- bottom number - pressure within the arteries when the heart is resting & filling with blood - sound of the beat fading away
43
Normal BP Range
- normal reading is 120/80 | - not common for a personal trainer to perform this BP assessment without additional training
44
Body Composition (4 methods)
1) skinfold measurements 2) bioelectric impedance 3) underwater weighing 4) circumference measurements
45
Skinfold Measurements
- prior to workout - not accurate for obese clients - measurements on the right side of the body - 4 measurement sites: biceps, triceps, subscapular, & iliac crest
46
Bioelectric Impedance
- conducts electric current through the body to estimate body fat % - uses scale or held in hands
47
Underwater Weighing
- hydrostatic weighing | - lean body mass weighs more underwater & body fat weighs less
48
Circumference Measurements
- measures girth of body segments (neck, chest, waist, hips, thighs, calves, & biceps) - good method for obese clients - can use online calculator to convert measurements to estimate body fat % - be consistent - waist to hip ratio (waist/hip = ratio)
49
Cardiorespiratory Assessments (2 ways)
1) YMCA 3-Minute Step Test | 2) Rockport Walk Test
50
5 Kinetic Checkpoints in anterior, lateral, and posterior views
Anterior view: foot and ankle; knees Lateral view: lumbo-pelvic-hip complex (LPHC); shoulders; head and cervical spine Posterior view: with experience; all checkpoints
51
Postural Assessments: know each and the things to observe
1) Overhead Squat Assessment 2) Single-Leg Squat Assessment 3) Pushing Assessment 4) Pulling Assessment
52
Performance Tests
1) Push-up test (muscular endurance of upper body) 2) Shark Skill Test (assess lower extremity agility & neuromuscular control) 3) Davies Test (measures upper extremity agility & stabilization) 4) Bench Press (estimate one-rep max on overall upper body strength) 5) Squat (estimate one-rep max on overall lower body strength)
