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 cellular respiration . ATP acts as the energy currency of cells and helps to meet all the energy requirements of the body.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

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
