|---|---|---|---|---|---|
| show | The skeletal muscle length changes & thus the load moves a measurable distance
🗑
|
||||
| Describe an isotonic concentric contraction | show 🗑
|
||||
| show | When a muscle generates a force greater than the load attached to the muscle's end. After the muscle tension exceeds the weight of load, an isotonic concentric contraction can begin
🗑
|
||||
| What happens when the latent period gets longer? | show 🗑
|
||||
| show | If the load is increased, the muscle must generate more force to move it and & the latent period will therefore get longer b/c it will take more time ton
🗑
|
||||
| show | Cross bridges cycle and when the muscle tension exceeds the load, muscle shortening happens. The latent period increases as the weight of the load gets heavier, this is for the necessary force to be generated by the muscle.
🗑
|
||||
| show | The latent period occurs when there is a rise in muscle tension but no movement or contraction of the muscle.
🗑
|
||||
| show | When the weight is heavy, the speed in which the muscle lifts the weight decreases in speed at a slower velocity.
🗑
|
||||
| What does the shortening-velocity refer to? | show 🗑
|
||||
| How does the shortening distance change as the load becomes heavier? | show 🗑
|
||||
| show | because as the weight of the load increases, so does the latent period time and the shortening velocity speeds. With the lighter weight, the muscle is contracted quicker in both latent and shortening velocity speeds.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
