Muscle and body fat do not play a role in BMI scales; age and gender however do play a role.
Heavy weight lifting is fitted on Anaerobic Activities
Heavy Weight lifting is considered short lasting-high intensity training which relies on on muscle strength rather than cardio vascular capabilities ( if it relies on cardio, it fitted on Aerobic Activities)
other Examples of anaerobic activity : Pull ups, Bench Press , Push up, etc
Answer:
Option). about 20 percent of the calcium ion required for contraction comes from outside the cell.
Explanation:
Calcium ions play an important role in cardiac muscle physiology. Calcium ions influx is responsible for plateau phase after depolarization. Calcium ions also play role in muscle contraction with the help of troponin (regulatory protein).
For contraction, about 20 percent of calcium ions are supplied from outside of the cell, while rest of the calcium ions are released from SR (sarcoplasmic reticulum).
Thus, the correct answer is 'forth option.'
