Strength in Aerials
Strength in Aerials - definitions of terms, types & examples of contractions
| Question | Answer |
|---|---|
| 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.) |
