Sample Answer
- Deep core muscles engage continuously around the spinal column during dance movements.
- As a result, constant stabilisation of the trunk occurs while limbs move dynamically.
- Muscles like transverse abdominis and multifidus maintain isometric contractions at 30-40% capacity throughout.
- This core engagement enables the skeletal framework to provide a stable central axis for movement.
- The skeletal system provides multiple balance points through joint positioning.
- Consequently, efficient weight transfer occurs as the body moves through dance positions.
- Ankles, knees and hips constantly adjust angles while the spine maintains vertical alignment.
- These skeletal adjustments thus allow muscles to control balance with minimal energy expenditure.
- Small postural muscles make continuous micro-adjustments during movement transitions.
- Such adjustments result in smooth, controlled shifts between dance positions.
- Proprioceptors detect tiny changes in joint position, triggering reflexive muscle responses within milliseconds.
- The rapid feedback system therefore ensures both systems work together to maintain dynamic stability.
