Q

How are muscular imbalances caused?

A

Muscular imbalances are caused by a variety of different things including emotional duress, repetitive movements, bad training techniques, the lack of neuromuscular efficiency, poor core strength, cumulative trauma and stress caused by postural problems.

Q

Obesity vs. Overweight

A

Being overweight is considered having a BMI index between the ranges of 25 and 29.9 and between 25 and 30 pounds over the recommended height to weight ratio. Being obese is considered having a BMI of 30 or more with at least 30 pounds overweight for the height to weight ratio.

Q

proprioception

A

Proprioception is the cumulative input into the central nervous system coming from the various Mechanoreceptors in the body that sense limb movement as well as body position. For example, while running your feet send proprioceptive feedback depending on the type of surface you are running on.

thick and thin filaments slide past one another shortening the entire sarcomere
28
type 1 (slow twitch) muscle tissue
smaller size; fatigue slowly
29
Type 2 (fast twitch) muscle tissue
larger size; quick to produce maximal tension, fatigue quickly
30
motor unit
one motor neuron and the muscle fibers it connects with
31
neural activation
contraction of a muscle generated by neural stimulation
32
neurotransmitters
chemical messengers that transport impulses from nerve to muscle
33
Local stabilization system
attach directly to vertabrae | consists of: transverse abdominis, internal oblique, multifidus, pelvic floor, diaphragm
34
global stabilization system
attach from pelvis to spine Consists of: quadratus lumborum, psoas major, external oblique, rectus abdominis, gluteus medius, adductor complex, portions of internal oblique
35
movement system
attach spine and/or pelvis to extremities | consists of: latissimus dorsi, hip flexors, hamstring complex, quadriceps
36
BMI
BMI = 703 × weight (lb) height2 (in2)
37
blood lipids
``` Also known as cholesterol and triglycerides, blood lipids are carried in the bloodstream by protein molecules known as high-density lipoproteins (HDL) (good) and low-density lipoproteins (LDL). (bad) ```
38
diabetes mellitus
``` Chronic metabolic disorder caused by insulin deficiency, which impairs carbohydrate usage and enhances usage of fats and proteins. ```
39
cholesterol levels
A healthy total cholesterol level is less than 200 mg/dL. A borderline high cholesterol level is between 200 and 239 mg/dL, and a high-risk level is more than 240 mg/dL
40
deconditioned
``` A state of lost physical fitness, which may include muscle imbalances, decreased flexibility, and a lack of core and joint stability. ```
41
physiological benefits of the OPT model
Improves cardiorespiratory effi ciency ◆ Enhances benefi cial endocrine (hormone) and serum lipid (cholesterol) adaptations ◆ Increases metabolic effi ciency (metabolism) ◆ Increases bone density
42
physical benefits of OPT model
Decreases body fat ◆ Increases lean body mass (muscle) ◆ Increases tissue tensile strength (tendons, ligaments, muscles)
43
performance benefits of OPT
``` ◆ Strength ◆ Power ◆ Endurance ◆ Flexibility ◆ Speed ◆ Agility ◆ Balance ```
44
Phases of training
Smaller divisions of training progressions that fall within the three building blocks of training.
45
muscular endurance
A muscle’s ability to contract for an extended period
46
neuromuscular efficiency
``` The ability of the neuromuscular system to enable all muscles to efficiently work together in all planes of motion. ```
47
stabilization stage
Th e main focus of this form of training is to increase muscular endurance and stability while developing optimal neuromuscular effi ciency (coordination). Th e progression for this level of training is proprioceptively based. Th is means that diffi culty is increased by introducing a greater challenge to the balance and stabilization systems of the body
48
Goals of phase 1 stabilization training
``` Improve muscular endurance » Enhance joint stability » Increase fl exibility » Enhance control of posture » Improve neuromuscular effi ciency (balance, stabilization, muscular coordination) ```
49
training strategies for stabilization
» Training in unstable, yet controllable environments (proprioceptively enriched) » Low loads, high repetitions
50
prime mover
The muscle that acts as the initial and main source of motive power.
51
superset
``` Set of two exercises that are performed back-to-back, without any rest time between them. ```
52
goals of strength in OPT model
Th e emphasis is to maintain stabilization endurance while increasing prime mover strength. Th is is also the level of training an individual will progress to if his or her goals FIGURE 1. 3 Proprioceptive push-up progression. 10 Section 1 – Fundamentals of Human Movement Science are hypertrophy (increasing muscle size) or maximal strength (lift ing heavy loads).
53
phase 2 goal of strength in OPT model
In Phase 2: Strength Endurance Training, the goal is to enhance stabilization endurance while increasing prime mover strength. Th ese two adaptations are accomplished by performing two exercises in a superset sequence Th e principle behind this method is to work the prime movers predominantly in the fi rst exercise to elicit prime mover strength. Th en, immediately follow with an exercise that challenges the stabilization muscles. Th is produces an increased ability to maintain postural stabilization and dynamic joint stabilization.
54
phase 3 OPT
Hypertrophy Training is designed for individuals who have the goal of maximal muscle growth (such as bodybuilders)
55
Phase 4 OPT goals
Th e premise behind this phase of training is 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. Th is is to enhance prime mover strength while also improving the rate of force production
56
rate of force production
Ability of muscles to exert maximal force output in a minimal amount of time.
57
OPT stands for
optimum performance training model
58
Phase 1 stabilization goals
``` Improve muscular endurance » Enhance joint stability » Increase fl exibility » Enhance control of posture » Improve neuromuscular effi ciency (balance, stabilization, muscular coordination) ```
59
Phase 1 training strategies
» Training in unstable, yet controllable environments (proprioceptively enriched) » Low loads, high repetitions
60
Phase 2 strength endurance goals
» Improve stabilization endurance and increase prime mover strength » Improve overall work capacity » Enhance joint stabilization » Increase lean body mass
61
phase 2 training strategies
» Moderate loads and repetitions (8–12) » Superset: one traditional strength exercise and one stabilization exercise per body part in the resistance training portion of the program
62
phase 3 hypertrophy goals
» Achieve optimal levels of muscular hypertrophy (increase muscle size)
63
phase 3 hypertrophy training strategies
» High volume, moderate to high loads, moderate or low repetitions (6–12)
64
phase 4 maximum strength training goals
» Increase motor unit recruitment » Increase frequency of motor unit recruitment » Improve peak force
65
phase 4 maximum strength training strategies
» High loads, low repetitions (1–5), longer rest periods
66
phase 5 power training goals
◆ Goals » Enhance neuromuscular effi ciency » Enhance prime mover strength » Increase rate of force production
67
phase 5 power training strategies
» Superset: one strength and one power exercise per body part in the resistance training portion of the program » Perform all power exercises as fast as can be controlled
