the ability of your musculoskeletal system to preform daily and recreational activities without undue fatigue or injury.
Muscular Strength
the ability of a muscle or group of muscle to contract with maximal force. describes how strong a muscle is or how much force it can exert.
Muscular endurance
the ability of a muscle to contract repeatedly over an extended period of time.
Resistance training
referred to as weight training or strength training and can be done with measured weights, body weight, or other resistive equipment. Stress the musculoskeletal system.
tendons
sheet of connective tissue that draws together at the ends of the muscle forming tendons.
muscle fibers
individual muscle cells.
fascicles
bundles of muscle fibers.
myofibrils
made up of actin and myosin
sarcomeres
myosin filaments exist in repeating units. smallest area in a muscle fiber where everything required for muscle contraction exists.
slow twitch
depend on oxygen
fast twitch
dont depend on oxygen.
isotonic
Type of contraction. Contractions are characterized by a consistent muscle tension as the contraction proceeds and resulting movement of body parts.
Isometric
a muscle contraction with no change in muscle length.
Isokinetic
a muscle contraction with a constant speed of contraction
Concentric
a muscle contraction with overall muscle shortening
eccentric
muscle contraction with overall muscle lengthening
hypertrophy
an increase in the size or cross sectional area of the protein filaments.
atrophy
a shrinking of the muscle to its pre training size and strength.
sarcopenia
poverty of flesh. term applied to age related loss in skeletal muscle, decreases muscle strength and endurance
muscle power
the capacity to exert force rapidly
calisthenics
conditioning that uses your body weight.
valsaiva maneuver
the process if holding ones breath while lifting heavy weight.
ergogenic aids
any nutritional, physical, mechanical, psychological, or pharmacological procedure or aid used to improve athletic performance.
