The Cell Fiber
Question | Answer |
---|---|
What are the 3 muscle tissue fiber types? | Red Slow Twitch (Type I), Red Fast Twitch (Type IIA), and White Fast Twitch (Type IIB). |
The Myofibrils in muscle tissue fibers are made up of two contractile proteins called.. | Actin and Myosin. |
The _______ is known as the 'powerhouse' of the cell. | Mitochondria. |
The Myofibrils are primarily affected by training what muscle tissue fiber? (4-6 rep range) | White fast twitch muscle fibers. |
What is the purpose of the Mitochondria? | To produce and store cellular energy. (ATP) |
What element manufactures body proteins? | The Ribosomes. |
The ribosomes occur in the _______ ___________ ___________. | Rough Sarcoplasmic Reticulum. |
What is the function of mRna in muscle tissue cells? | To take instruction from the DNA to the Ribosomes. |
What is the purpose of the Myofibrils? | Allow the muscle to contract. Allows for strength and performance of work. |
What type of exercises would primarily result in a larger amount of Cellular Energy Depletion? | Light, high repetition sets, including lots of compound movements. (The more muscles used, the greater the energy used!) |
To offset energy depletion and lactic acid build up, what should be done? | Rest MOMENTARILY between REPETITIONS. This allows for a greater amount of oxygen to be taken to the working muscle fibers, and lessens the use of stored muscle glycogen.) |
Offsetting energy depletion should NOT be followed in what type of training? | During heavy intense training BECAUSE it can possibly cause hard tissue injury to client) |
