Strength in Aerials

Strength in Aerials - definitions of terms, types & examples of contractions

QuestionAnswer
What is the definition of 'muscular strength'? The amount of force a muscle can produce with a single maximal effort. (how many kgs you can lift in one rep)
What is the definition of 'muscular endurance'? The ability of muscles to exert force against resistance over a sustained period of time. (# of repetitions)
What is the definition of 'muscular power'? The combination of muscular force and the speed of movement (slow squat vs. squat jump)
What is the definition of an isotonic concentric muscular contraction? Muscle shortens and causes movement at joint
What happens to the joint ANGLE in an isotonic concentric muscular contraction? Angle at joint decreases
What is the definition of an isotonic eccentric muscular contraction? Muscle lengthens and controls movement at joint
What happens to the joint ANGLE in an isotonic eccentric muscular contraction? Angle at joint increases
What is the definition of an isometric muscular contraction? Muscle holds tension without changing in length to stop movement at joint
What happens to the joint ANGLE in an isometric muscular contraction? No change occurs, it is a static contraction.
What type of contraction is being used in the following scenario? aerials movement - chin up muscle being described - biceps Isotonic Concentric
What type of contraction is being used in the following scenario? aerials movement - straddle up/inversion muscle being described - abdominals Isotonic Concentric
What type of contraction is being used in the following scenario? aerials movement - Catcher's Genie muscle being described - hamstrings Isometric
What type of contraction is being used in the following scenario? aerials movement - slowly lowering feet to mat muscle being described - abdominals Isotonic Eccentric
What type of contraction is being used in the following scenario? aerials movement - reverse chin up (from bent arm hang to straight arm hang) muscle being described - biceps Isotonic Eccentric
What type of contraction is being used in the following scenario? aerials movement - End of T flip (in crucifix shape) muscle being described - pectoralis major (chest) and latissimus dorsi (wing muscles) Isometric
What type of contraction is being used in the following scenario? aerials movement - Side crunch with scissor legs (at start of fan kick hip lock) muscle being described - obliques (side abdonminals) Isotonic Concentric
What type of contraction is being used in the following scenario? aerials movement - straddle up/inversion (starting from bent arm hang) muscle being described - biceps Isotonic Eccentric
How do muscles attach to bones? Via tendons
What happens to the muscle fibres during an isotonic concentric contraction? The individual fibres draw closer together, which shortens the muscle.
How do you increase muscular strength? Resistance training (using body weight and gravity or additional weight/resistance via straps, hand weights, gym machines, barbells, etc.)
