25
motor unit
the combination of motor neuron and muscle fibers that the neuron innervates
26
slow-twitch fibers
muscle fibers with greater aerobic potential and slow speed of contraction
27
fast-twitch fibers
muscle fibers with greater anaerobic potential and fast speed of contraction most important in strength related activities
28
factors that affect strength
``` neural stimulation type of muscle fiber overload specificity of training training volume periodization ```
29
neural stimulation
number of nerve fibers innervated and frequency of stimulation determine strength of the muscle contraction
30
short term gains
usually gains in first 2-3 weeks are due to enhanced neural function by increasing motor neuron stimulation and muscle fiber recruitment
31
longer term gains
primarily related to physiological adaptation within the muscle and to a lesser extent neural adaptations
32
type of muscle fiber
slow-twitch fibers fast-twitch fibers mix is genetically determined
33
Fiber activation
slow twitch fibers are always recruited first | to activate fast twitch fibers, an activity must be intense and powerful
34
overload principle
training concept that the demands placed on a system must be increased systematically and progressively over time to cause physiological adaptations
35
strength gains achieved in two ways
- increased ability of individual muscle fibers to generate a stronger contraction - recruiting a greater proportion of the total available fibers for each contraction
36
procedures used to overload in strength training
- increase intensity (weight/resistance) - increase number of reps - increase or decrease speed of reps - decrease the rest interval for endurance improvements (lighter resistances) or lengthening rest interval for strength and power development (higher resistances) - increasing volume - combination of the above
37
specificity of training
principle that training must be done with the specific muscle(s) the person is attempting to improve
38
specific adaptation to imposed demand training
SAID training -training principle stating that for specific improvements to occur in a specific activity, the exercises performed during a strength-training program should resemble as closely as possible the movement patterns encountered in that activity
39
volume
in strength training - the sum of all repetitions performed multiplied by resistances used during strength training session
40
Volume changes used to
hypertrophy - high volume, low intensity | increase strength/power- low volume, high intensity
41
periodization
training approach that divides the season into three cycles using systemic variation in intensity and volume of training to enhance fitness and performance
42
training cycles
macrocycles mesocycles microcycles
43
periodization cycles
hypertrophy strength endurance
44
periodization used to prevent
overtraining
45
overtraining
an emotional, behavioral and physical condition marked by an increased fatigue, decreased performance, persistent muscle soreness, mood disturbances and feelings of staleness or burnout as a result of excessive physical training
46
classical periodization
used for max strength development | starts with high volume/low resistance and switches to low volume/high resistance
47
reverse periodization
used for greater muscular endurance | starts with low volume/high resistance and switches to high volume/low resistance
48
undulating periodization
alternates between muscular fitness components of strength, hypertrophy, power and endurance
49
principles of strength training
``` mode resistance sets frequency volume ```
50
training modes
isometric training | dynamic training
51
isometric training
muscle contraction that produces little or no movement, pulling against an immovable object - gains specific to angle of muscle contraction - critical to low back spinal stabilization
52
dynamic training
muscle contraction with movement - most common - strength gained through full range of motion
53
dynamic training consists of 2 actions
- concentric or positive resistance | - eccentric or negative resistance
54
Range of motion
entire arc of movement of a given joint
55
concentric
shortening of a muscle during contraction
56
positive resistance
the lifting, pushing, or concentric phase of a repetition during a strength-training exercise
57
eccentric
lengthening of a muscle during muscle contraction
58
negative resistance
the lowering or eccentric phase of a repetition during strength training
59
free weights
barbells and dumbbells
60
fixed resistance
constant resistance is moved through a joints full range of motion (dumbbells and machines with constant resistance
61
variable resistance
special machines equipped that provide different amounts of resistance throughout the range of motion
62
dynamic constant external resistance
DCER - Fixed resistance
63
isokinetic training
speed of the muscle contraction is kept constant because the machine provides accommodating resistance to match the user's force through the range of motion
64
resistance
amount of weight lifted
65
progressive resistance
a gradual increase in resistance over time
66
circuit training
alternating exercises by performing them in a sequence of 3 to six or more
67
plyometric exercise
explosive jump training, incorporating speed and strength training to enhance explosiveness
68
core strength training
program designed to strengthen the abdominal, hip and spinal muscles (core of the body)
69
pilates
uses exercises designed to help strengthen the body's core by developing pelvic stability and abdominal control; exercises coupled with focused breathing patterns
