Section 3 Flashcards
What’s actions occur in the Sagittal Plane?
Flexion, Extension, Dorsiflexion, and Plantar Flexion
What’s actions occur in the Frontal Plane?
Abduction, Adduction, Elevation, Depression, Inversion, and Eversion
What actions occur in the Transverse Plane?
Rotation, Pronation, Supination, Horizontal Flexion, and Horizontal Extension
What actions are Multiplanar?
Circumduction and Opposition
What is Skeletal Muscle?
Muscle tissue that is considered voluntary. (Striated muscle)
What is Smooth Muscle?
Muscle tissue fold in walls of organs and tubes in the body. Considered involuntary.
What is Cardiac Muscle?
Forms walls of the heart, functions to maintain pumping of the heart. Involuntary muscle. (Striated)
Describe a Closed Kinetic Chain Exercise
An exercise where the end farthest away from the body is fixed. Usually involves more muscles and joint.
(Feet in a squat)
Describe an Open Kinetic Chain Exercise
A movement when the end farthest from the body is free.
(Seated leg extension)
Describe Wolf’s Law
When skeleton is subjected to stressful force, it reacts by creating more bone tissue which increases its density.
Describe Myofibillar Hypertrophy
Increase number of myofibrils (contractile protein) in the muscle cell as a response to training, resulting in greater muscle contraction force.
What is Sarcoplasmic Hypertrophy
Increase sarcoplasm in the muscle cell from training, increasing the cross-sectional area and size of the muscle.
Related to transient hypertrophy (muscle pump).
What is Cardiac Output
Product of heart rate and stroke volume, or quantity of blood pumped per heartbeat.
What is the average RHR
60-70 bpm
What is the formula for BMI
Weight (Ib) / Height Squared (in) x 703
What is the normal blood pressure numbers
Normal: <120/<80
Stage 1 (Hypertension): 130-139/80-89
What is the most used method to estimate body fat
Skinfold Measurements
What body fat % and waist circumference can you expect to lose in 2-3 months
Body Fat %: 2.7-5.9%
Waist Circumference: 1.9-3.3 cm
What are the BMI classifications
Normal: 18.5-24.9
Obesity: 30.0-34.9
What is Arteriosclerosis
Narrowing and hardening of arteries due to plaque accumulation (common in elderly) and decreases arteries ability to expand.
What is the Cardiac Cycle
The time between the start of one heartbeat to the start of another.
What are the general training volumes for someone training are strength
2-6 set x 3-6 reps, +85% 1RM with 2-5 mins rest intervals
What the primary muscles and functions of the ankle & foot
Anterior tibialis: Dorsiflexion at the ankle, inversion at the foot
Gastrocnemius: Plantar flexion at the ankle, eversion at the foot
What the primary muscles and functions of the knee
Rectus femoris: Extension
Biceps femoris: Flexion & external rotation
