Why does a person with muscles that have a higher percentage of slow fibers have greater endurance than a person with muscles that have a lower percentage of slow fibers?
Step by step
Solved in 3 steps
- In a general sense, how do skeletal muscles produce movement?why does a person with muscles that have a higher percentage of slow fibers have greater endurance than a person with muscle that have a lower percentage of slow fibers?Which of the following is not true when comparing slow twitch red and fast twitch white muscle fibers? Question 2 options: a) Red contain more mitochondria than white b) Red contain more myoglobin than white c) Red contracts more slowly than white d) Red contain more glycogen stores than white
- Slow twitch muscle fibers are characterized by all of the following EXCEPT: O a) used in endurance type of activities O b) contract rapidly and forcefully Oc) resistant to fatigue O d) have a direct relationship to the oxidative energy systemWhere do you get the energy to contract your muscles and when do you use it? When do you use the sources above?Why might stretching a cramping muscle INCREASE the cramping, as well as why would contracting the opposing muscle rapidly improve the situation?
- Why does repeated stimulation of the muscle (at maximum stimulus) before it has completely recovered from the previous contraction lead to increasing force of contractions?How does the frequency of action potentials affect musclecontractions?Which of the following does NOT describe treppe? It is also referred to as the "staircase" effect. An increase in stimulus intensity is required to see the effect. An incremental increase in force occurs. A period of relaxation can be seen on the muscle twitch tracing.
- What is the physiological function of exercise to muscles?Hello Why does a person with muscles that have a higher percentage of slow fibers have greater endurance than a person with muscles that have a lower percentage of slow fibers? Thank you!We control muscle force using motor unit recruitment. When we recruit more motor units, what is happening at the organ/cell/molecular level? more myofibrils within a muscle cell are activated more muscle cells are excited the rate of crossbridge cycling is increased the number of myosin heads bound to actin within a muscle cell is increased more Ca++ is released into the cyoplasm of the muscle cell
