Based on changes in amplitude and frequency of sEMG, did motor unit activation increase, decrease, or stay the same with increasing muscle load? The motor unit activation increased with muscle load based on the changes in amplitude and frequency of sEMG because the motor units which are activated are contracting at a greater frequency. 8. Do you think that the force of isometric contraction increased, decreased, or stayed the same as muscle load increased? The force of the isometric contraction increased as the muscle load increased.

Estimate the length of the refractory period for the pyramidal neuron.50msec DISCUSSION 1. In Experiment 1, discuss why the amplitude of the action potential did not increase as stimulation voltage increased above threshold. Once over threshold, the maximum amplitude is no longer able. The action potential is everything or nothing. 2.
Action Potential Generation. Location Stimulation voltage 0 V (no stimulation ) 2 V 4 V 6 V 8 V Action potential generated? NO NO NO YES YES Difference in action potential amplitude with distance -0.4 9.4 8.2 0.1 98.2 Graph 1. Maximal depolarization of membrane potential at axon hillock and axon after different stimulation voltages. Resting membrane potential = -70 mV.
Could Exercise Really Play a Role in Your Health? Blood Pressure Could Exercise Really Play a Role in Your Health? Blood Pressure Introduction Blood pressure (BP) is defined “as the pressure the blood exerts against any unit area of the blood vessel walls, and it is generally measured in the arteries. Because the heart alternately contracts and relaxes, the resulting rhythmic flow of blood into the arteries causes the blood pressure to rise and fall during each beat. Thus you must take two blood pressure readings: the systolic pressure, which is the pressure in the arteries at the peak of ventricular ejection, and the diastolic pressure, which reflects the pressure during ventricular relaxation.
