In the previous question, you identified the individual who was completing aerobic exercise. This aerobic exercise helps to increase , or the ability to perform moderate-to-high-intensity activity involving large muscle groups for long periods of time. a.flexibility b.cardiorespiratoryfitness c.muscuskeletal fitness Identify the activities that would most likely improve an individual’s cardiorespiratory fitness. Check all that apply. Front squatting Running Swimming Yoga The excitation, contraction, and relaxation of skeletal muscle require the use of ATP. Because only limited stores of ATP are immediately available in muscle tissue, ATP must be continually supplied if contractile activity is to continue. Depending on the type of movement or exercise, one or more pathways can be used to provide the most efficient way of supplying the ATP. © John P. Kelly / Getty Images For example, a cross-country skier who skis continuously for two hours during a training exercise will need ...... a.short bursts b. a sustained source of ATP. As a result, which of the following pathways would be best suited to this type of activity? a.Using creatine phosphate b.Glycolysis c.Oxidative phosphorylation To prepare for the cross-country meet, a skier decides to significantly increase the amount of carbohydrates in his diet (a technique also known as carbohydrate loading). Why might this be beneficial to the cross-country skier? Check all that apply. Carbohydrates are used to build actin filaments in the myofibrils, which increases muscle bulk and performance. The liver can store copious amounts of ingested carbohydrates as glycogen, which can then be slowly broken down to release the glucose needed to fuel aerobic respiration. As long as oxygen is present, the glucose stored in the ingested carbohydrates can provide a steady stream of ATP, thus meeting the demands of prolonged periods of exercise. Eating more carbohydrates leads to more glycogen stores in muscles, which then equates to larger energy stores for short, explosive bouts of energy use.
1. Aerobic exercise that helps to increase or the ability to perform moderate-to-high-intensity activity involving large muscle groups for long periods of time is cardiorespiratoryfitness . Cardiorespiratory fitness uses aerobic exercise and it helps to maintain the cardiorespiratory endurance .
2. The activities that would most likely improve an individual’s cardiorespiratory fitness are Running ,Swimming and Yoga.
3. A cross-country skier who skis continuously for two hours during a training exercise will need a sustained source of ATP because his muscles continuously need oxygen supply .
4. The pathways that would be best suited to this type of activity is Glycolysis. It results in the conversion of glucose to carbon compounds, a glucose molecule produces pyvuric acid and ATP .

Which of the following statements best describes the difference between aerobic and anaerobic metabolism? Check all that apply. - Anaerobic metabolism produces more ATP than aerobic metabolism. - Anaerobic metabolism produces less ATP than aerobic metabolism. - Only aerobic metabolism can occur in the absence of oxygen. - Anaerobic metabolism does not produce lactate while aerobic metabolism does. - Both anaerobic and aerobic metabolism run through glycolysis, Krebs cycle, and the electron transport chain. - Only anaerobic metabolism can occur...

1. A closer look - Muscles and their role in health and
energy needs of athletes
Skeletal muscles, which move bones, consist of cells fused into
long fibers. These muscle fibers can increase in size when
contracted, which is what happens as a result of some exercise.
This animation shows the structure of vertebrate skeletal muscles.
It starts at a large scale, showing the muscles of a human upper
arm, and then gradually zooms in to smaller and smaller levels,...

1. A patient presents in your surgery with an inability to maintain blood sugar levels in long periods (20 hours) between meals. Tests show that glucose is converted to lactate normally in liver in the well-fed state, and that pyruvate carboxylase and phosphoenolpyruvate carboxykinase have normal activities in liver in periods between meals. Your colleague reminds you that glucagon stimulates glycogen degradation, so you administer glucagon to the patient (who was well fed prior to the test) and find that...
