Consider the factors that affect muscular strength. Read each scenario and then click and drag each label into the appropriate category based on whether each would result in a stronger or weaker muscle contraction.

1- Potassium accumulate in the sarcoplasm
2- Increase in muscle belly circumference
3- Lesser proportion of motor neurons to muscle fibres
4- Begin contractions with muscle already 50% contraction
5- Lower sarcoplasm pH
6- Increased stimulus frequency.
7- Circular arrangement of muscle fascicles
8- increased requirement
