Question
Chapter 33.2, Problem 1TC
Summary Introduction
To determine:
The resting heart rate of a well conditioned athlete is slower than the heart rate of a less active person.
Introduction:
Heart is the muscular organ present in most animals. Heart serves as the pump to circulate the blood. The heart has four chambers. The cardiac muscles are of two types’ myocardial contractile cells and myocardial conducting cells.

Cycling is a form of exercise known to increase the heart rate. For cycling, four incline levels typically determine how much more intense you would like the workout to be. Level one is a walking pace, two is slightly more difficult, three is like cycling up a hill, and four is the most intense like cycling up a mountain. I will test the heart rate to see how it increases or decreases depending on each incline level. The moderate activity would be levels one and two, while the strenuous activity would be levels three and four.
Before beginning the exercise, I will sit on the bike in a resting position to get my resting heart rate.
Then I will start the stopwatch on the bike that records my cycling time, heart rate, and RPM (revolutions per minute). I will start at level one for five minutes and then record my heart rate after the session.
I will rest for five minutes and then repeat the same process for each incline level (three more times; four in total).
What may be the…
You are at the gym and doing strength training. You feel in good shape and should try to break personal records in squats. You place the bar on your back and begin to take in, that is, your motor neurons begin to send action potentials through all your motor units to the thigh muscles.
What is the contraction called when you a) bend down and b) are in good shape and can generate more force than the bar weighs c) stay standing in one and the same position without being able to push yourself up in a standing position?
What are the major factors that determine the contraction of skeletal muscle? What is the role of Calcium. Identify the similarities and differences comparing skeletal muscle contraction and relaxation to cardiac muscle.
