HIIT Flashcards
Muscles consist of many
Muscle fibers(cells) connected
In bundles called
FASCICLES.
Muscle Fibers Are Made Up Of
MYOFIBRILS
Strength training increases
The number of myofibrils and
The size of muscle fibers
HYPERTROPHY
Inactivity Reverses The Process
ATROPHY
Rely on aerobic
Respiration to fuel muscle contractions and
Are ideal for long term endurance.
SLOW-TWITCH FIBERS
Rely on anaerobic
Respiration to fuel muscle contractions and
Are ideal for quick contractions of short
Duration.
FAST-TWITCH FIBERS
Benefits of muscular
Strength and
Endurance
IMPROVED PERFORMANCE OF PHYSICAL
ACTIVITIES
INJURY PREVENTION
IMPROVED BODY COMPOSITION
ENHANCED SELF-IMAGE AND QUALITY OF
LIFE
IMPROVED MUSCLE AND BONE HEALTH
WITH AGING
PREVENTION AND MANAGEMENT OF
CHRONIC DISEASE
MUSCLE CONTRACTION WITHOUT A
CHANGE IN THE LENGTH OF THE MUSCLE.
STATIC (ISOMETRIC) EXERCISE
TYPES OF STRENGTH
TRAINING
EXERCISES
DYNAMIC (ISOTONIC) EXERCISE
MUSCLE CONTRACTION WITH A
CHANGE IN THE LENGTH OF THE MUSCLE.
TYPES OF STRENGTH
TRAINING
EXERCISES
MUSCLE APPLIES FORCE AS IT
SHORTENS
CONCENTRIC CONTRACTION
MUSCLE APPLIES FORCE AS IT
LENGTHENS
ECCENTRIC CONTRACTIONS
DEFINED AS
RHYTHMIC MUSCULAR ACTIVITY
RESULTING IN MOVEMENT, AND IT
INITIATES A MORE APPROPRIATE
INCREASE IN CARDIAC OUTPUT AND
OXYGEN EXCHANGE.
DYNAMIC EXERCISE
CHANGING LOAD TO
PROVIDE MAXIMAL RESISTANCE THROUGHOUT
A JOINT’S RANGE OF MOTION.
VARIABLE RESISTANCE
PLACING LOAD ON A
MUSCLE AS IT LENGTHENS
ECCENTRIC LOADING
A TYPE OF
EXERCISE THAT TRAINS MUSCLES TO PRODUCE
POWER (STRENGTH + SPEED). PLYOMETRIC
EXERCISES INVOLVE A STRETCH OF THE
MUSCLES, IMMEDIATELY FOLLOWED BY A
CONTRACTION OF THE SAME MUSCLES
PLYOMETRICS
