does the amplitude of the EMG signal and the force of contraction increase because a finite number of fibers or are fiting more often, or becasue more fibers are recruited to fire as the intensity of signals in the motorneurons increase, or a combination of the two?
The amplitude of a wave can be increased by changing the energy or force producing the wave. This can be done by increasing the magnitude of the source creating the wave, such as by increasing the power of a sound source or increasing the voltage of an electrical signal. Additionally, the amplitude of a wave can also be increased by using a device that amplifies the signal, such as an amplifier for an electrical signal or a horn for a sound wave.
To increase the amplitude of a wave, you can increase the energy or force that is driving the wave. For example, for a sound wave, increasing the volume or intensity of the sound source will increase the amplitude of the wave. Similarly, for a water wave, increasing the force or energy creating the wave will result in a larger amplitude.
You can increase the amplitude of a longitudinal wave by increasing the energy or force that is causing the wave to propagate. This will result in higher density or compression regions in the wave, which increases its amplitude.
To increase the amplitude of a drum, you can hit it harder or with more force. This will cause the drumhead to vibrate more intensely and produce a louder sound. Additionally, using larger drumsticks or mallets can also help increase the amplitude of the drum's sound.
Inotroph refers to the hearts force of contraction. Positive inotroph therefore refers to the hearts ability to increase its force of contraction in response to a stimulus.
One way to increase the amplitude of a wave in a medium is to add more energy to the system. This can be done by increasing the force or energy input driving the wave, which in turn will lead to a higher amplitude.

Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
The relationship between amplitude and force is that the force required to maintain a certain amplitude of oscillation in a system is directly proportional to the square of the amplitude. This means that as the amplitude increases, the force required to sustain that motion also increases quadratically.

To make the peak or crest of a wave higher, you can increase the amplitude of the wave. Amplitude refers to the maximum distance a particle moves from its rest position. By increasing the energy or force behind the wave, you can increase its amplitude, resulting in a higher peak or crest.
