Card preview (16)
Muscular fitness contributes to?
Fat free mass resting metabolic rate cardio fitness
Strength/muscular endurance?
The ability to repeatedly perform or maintain submaximinal contractions for an extended duration
Flexibility?
Functional capacity of the joints to move through a full range of motion (ROM)
Concentric?
Muscle shortens
Eccentric?
Muscle lengthens
Isometric?
Same length
Isokinetic?
Resistance varies with consistent speed of contractions
Muscle size?
Increased muscle cross-sectional area relates to strength in those muscles
Atrophy?
Loss of muscle
Hypertrophy?
Muscle gain
Neutral control?
Learning effects for movements Synchronisation of motor units Coordinating synergists and antagonists Rate coding (firing frequency)
Fatigue resistance?
Size and density of mitochondria Amount of oxidative enzymes Increased capillary density Improved buffering capacity
Weight management - increased muscle: fat ratio?
Body burns more energy at rest
Paint management of muscular fitness?
Strengthing lumbar and cervical extensors can significantly reduce neck pain Stretching the back extensors, hip rotators and hip extensors can reduce back pain
Psychological benefits of muscular fitness?
Reduce cognitive decline improved sleep reduced anxiety Improved self esteem
Injury prevention?
Strengthens tissues which provide support to joints
