• Another key realations ship is the Load/Velocity relationship.
• Simply stated, the relationship says that when a heavier load is applied to a muscle it will shorten with a lower velocity.
• From this relationship, we acquire 2 values:
• Vmax - The maximum velocity attainable by the muscle under NO load.
• The Vmax is dependent on the ATPase activity of the myosin in the muscle.
• Fmax - The maximum stress which the muscle can bear with NO muscle contration.
• The Fmax is dependent on the number of crossbridges between actin and myosin
