Summary Introduction
To review:
The reason for the continued high heart rate on the first day of aerobic exercise.
Given:
An individual has just joined a class of aerobics exercise for the first time and calculates the heart rate. After the class, they notice that the rate of the heart remains high for some time and gradually falls and return to the normal state.
Introduction
Muscles are the tissue in the body that is fibrous in nature. Muscles utilize oxygen person breathe to break down the glucose molecule to produce ATP (adenosine triphosphate) and this process is known as

Most immediate physiological adjustments to exercise occur prior to any change in tissue metabolic demand for oxygen or nutrients. This occurs because exercise increases sympathetic nervous system activity. With your knowledge of exercise and the control of alpha motor neurons by the primary motor cortex of the brain, how does increased exercise influence the sympathetic nervous system?
The motor unit firing patterns are measured in a human hand muscle using an electromyography (EMG) recording. Which one of the following statements is the best description of the EMG pattern observed as the individual voluntarily attempts to make a low-level force of contraction in the muscle and steadily increases the force of contraction?
Low amplitude spikes visible on the EMG trace at low force. Larger amplitude spikes become visible with increasing force of contraction.
Low frequency of small amplitude spikes on the EMG trace at low force. Spike frequency and amplitude increase with increasing force.
A large single deflection in the trace as the individual contracts the muscle. The deflection gets larger with increasing force.
Low frequency of spikes on the EMG trace at low force. The frequency of spikes becomes more frequent with increasing force.
Which of the following is a correct sequence (in chronological order of occurrence) within excitation-contraction coupling?
a. Synpatic vesicles fuse with the pre-synaptic membrane, Neurotransmitter binds to receptors in the post-synaptic membrane, Neurotransmitter diffuses across the synaptic cleft
b. Neurotransmitter binds to receptors in the post-synaptic membrane, Synpatic vesicles fuse with the pre-synaptic membrane, Neurotransmitter diffuses across the synaptic cleft
c. Synpatic vesicles fuse with the pre-synaptic membrane, Neurotransmitter diffuses across the synaptic cleft, Neurotransmitter binds to receptors in the post-synaptic membrane

- When electrically stimulating a skeletal muscle and measuring the force of muscle contraction, which of the following are true? Check All That Apply Increasing the stimulus will increase the muscle contraction force. The recruitment of motor units will increase the muscle contraction force. One weak stimulus will cause an increase in muscle contraction force. Increasing the force will increase the muscle contraction stimulus. Once maximum stimulus has been reached, the muscle will not contract with increased force.arrow_forwardFrom the following choices, choose the THREE, that would result in prevention of muscle contraction (in other words, which three descriptive changes below would result in flaccid paralysis of a muscle). exocytosis of acetylcholine is constant, even without action potential injection of botulinum toxin calcium cannot be pumped back into the terminal cisternae acetylcholine receptor remains open to sodium active sites on actin a permanently exposed dramatically increase the activity of acetylcholinesterase calcium cannot bind troponinarrow_forwardIf you were to administer a graded exercise test, which of the following listed below would you not expect to find? none of the answers are correct approximately linear increase in heart rate with increasing work rate approximately linear increase in systolic blood pressure with increasing work rate failure of diastolic blood pressure to increase with increasing work ratearrow_forward
- Some cardiac drugs have effects on exercise. Which drugs specifically affect exercise and how? If you worked in cardiac rehab how would you deal with these effects (answer for each type of drug that affects exercise)?arrow_forwardWe have looked at exercise from a couple of perspectives now. Of the sets of physiological parameters below, which is a combination of one parameter that increases, one that decreases and one that doesn't change with vigorous exercise in that order? Tidal volume, Inspiratory reserve volume, stroke volume Forced vital capacity, heart rate, cardiac output Hematocrit, forced vital capacity, respiratory rate Stroke volume, expiratory reserve volume, forced vital capacity Heart rate, tidal volume, hematocritarrow_forwardIf someone trains at high intensities in both aerobic and resistance exercise, which adaptation will ultimately win? How? Why?arrow_forward
- How would exposure to a sarin or sarin-like chemical affect calcium levels inside the sarcoplasmic reticulum (SR) of a skeletal muscle? Group of answer choices An increased frequency of action potentials would lead to decreased calcium levels in the SR A decreased frequency of action potentials would lead to decreased calcium levels in the SR An increased frequency of action potentials would lead to increased calcium levels in the SR A decreased frequency of action potentials would lead to increased calcium levels in the SR pick one answerarrow_forwardBFR O Is an example of "gym science" that has no merit as a training tool was devised at Ball State Exercise Physiology laboratories to improve response to weight training at safer lower loads restricts blood flow to exercising muscle to improve response to resistance training stands for basal flow rate, a key determinant of muscle oxygenationarrow_forwardThe changes related to muscle mobility are the most obvious in older adult. There can be measurable differences in muscle strength, endurance, range of motion, coordination, elasticity, and flexibility of connective tissue. Regular exercise is necessary to prevent a decrease in muscle strength. Exercise helps to strengthen muscles and keeps joints, tendons, and ligaments more flexible, allowing for a more active lifestyle. Please research and describe some activities you could recommend to an elderly patient to stay active to help them maintain muscle massarrow_forward
