The force–frequency relationship refers to the phenomenon in which the isometric force produced by a muscle increases with the frequency of activation, resulting in a sigmoidal curve which plateaus at the high frequencies.
Q. What is stimulus frequency?
Stimulus intensity describes the amount of force generated to administer the stimulus while stimulus frequency refers to the rate of delivered stimulus to the muscle.

Q. What happens to force production with each subsequent stimulus in Activity 3?
What happens to force production with each subsequent stimulus? Force increases with each subsequent stimulus.
Q. Which of the following is true of the maximum stimulus frequency?
2. Which of the following is true of the maximum stimulus frequency? No greater muscle force can be generated and the muscle has reached maximal tetanic tension.
Q. Does latent period change with different stimulus voltage?
The latent period did not change with changes in stimulus voltage.
Q. What has happened in the muscle when maximal stimulus is achieved?
What has happened in the muscle when the maximal stimulus is achieved? Cross bridge 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.
Q. What does stimulus frequency refer to?
Stimulus frequency refers to. the rate that stimulating voltage pulses are applied to an isolated whole skeletal muscle.
Q. What happens around 80 msec?
What begins to happen at around 80 msec? Fused tetanus develops at this greater stimulus frequency. Muscle tension increases and decreases between different values for an unfused tetanus.
Q. Why does the stimulated muscle force began to decrease?
Why does the stimulated muscle force begin to decrease over time despite the maintained stimuli? (Note that a decrease in maximal force indicates muscle fatigue is developing.) the number of active cross bridges begins to decline although the rate of stimulus delivery (frequency) remains constant.
Q. Why does force decrease with time?
Why does the force begin to decrease with time? Because there is not enough ATP being produced to allow the muscle to contract that many times and for the length of time.
Q. How can humans delay the onset of muscle fatigue?
Rest/Recovery – Complete a warm up and cool down for 5 to 10 minutes each time you exercise. Start off slowly and gradually increase workout intensity levels so that your muscles are gradually challenged and can build over time. Allow adequate rest between workout sessions and strength repetitions.
Q. What happens during muscle fatigue?
Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following strenuous activity or exercise. When you experience fatigue, the force behind your muscles’ movements decrease, causing you to feel weaker.
Q. What must be done after muscle fatigue is experienced in order for the body to recover?
If your muscles are sore and fatigued after exercise, experts recommend applying an ice pack to the affected area for a while, switching to a hot pack, and alternating for a couple of hours.
Q. Does lack of oxygen cause muscle fatigue?
One of the important roles of blood flow is to provide O2 to the working muscles. It has been well documented that decreased oxygen availability to exercising muscle has profound consequences on muscle fatigue.
Q. How do you reduce lactic acid build up?
- Stay hydrated. Make sure you’re staying hydrated, ideally before, during, and after strenuous exercise.
- Rest between workouts.
- Breathe well.
- Warm up and stretch.
- Get plenty of magnesium.
- Drink orange juice.
Q. What happens when your muscles don’t get enough oxygen?
When your body runs out of oxygen, or your other systems can’t deliver oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead.
Q. What is the main cause of muscle fatigue?
Intracellular acidosis due mainly to lactic acid accumulation has been regarded as the most important cause of skeletal muscle fatigue.
Q. How do you know if you have muscle weakness?
sudden onset of muscle weakness. sudden numbness or loss of feeling. sudden difficulty moving your limbs, walking, standing, or sitting upright. sudden difficulty smiling or forming facial expressions.
Q. What supplement is good for muscle fatigue?
Beta-Alanine. Beta-alanine is an amino acid that helps fight muscle fatigue. When acid starts to build up in your body during intense exercise, beta-alanine helps combat the acid (13). Taking beta-alanine as a supplement increases its concentration in the body and may improve exercise performance.
Q. What vitamin helps with muscle control?
Vitamin D is essential for your muscles to function normally. As per a study, a Vitamin D deficiency leads to proximal weakness and reduced muscle mass. It also puts you at an increased risk of falling. Vitamin D can be used to help patients suffering from muscle pain or weakness.
