|---|---|---|---|---|---|
| show | The skeletal muscle length changes & thus the load moves a measurable distance
🗑
|
||||
| show | The muscle length shortens as the load moves
🗑
|
||||
| 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 🗑
|
||||
| What happens to the muscle when load is increased? | show 🗑
|
||||
| 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.
🗑
|
||||
| When does the latent period occur? | show 🗑
|
||||
| Explain why the shortening load becomes slower as the load becomes heavier. | show 🗑
|
||||
| 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.
