ACE Quiz Questions I got wrong
Terms in this set (16)
A participant in your class informs you that she has osteoporosis primarily in her axial skeleton. Which exercise is her physician MOST likely to suggest?
Maintaining or improving muscular balance across the joints is particularly important for people with osteoporosis. It can also help to prevent falling.
A regular exercise participant in your class suffers from osteoarthritis of the knee. Which of the following is MOST affected by this condition?
Osteoarthritis is a degenerative joint disease characterized by cartilage deterioration that results in pain and loss of movement as bone surfaces interface.
Which of the following is defined as an excessive posterior curvature of the spine that is often seen in the thoracic region?
Kyphosis is an excessive posterior curvature of the spine, typically seen in the thoracic region.
During plyometric exercises, the ground exerts a force against the body equal to the force that the body applies to the ground. What biomechanical principle BEST explains this force?
Newton's law of reaction
Newton's third law, the law of reaction, states that for every action there is an equal and opposite reaction. This would define the force that the ground exerts against the body as equal to the force that the body applies to the ground.
What type of training could include completing a certain number of days that involve intense or more difficult exercise followed by a similar number of easy or light training days?
Periodization training alternates easy, moderate, and hard periods of training. It applies the overload concept through a pre-planned variation of program components to optimize gains in fitness, while preventing overuse, staleness, overtraining, and plateaus.
Which of the following statements regarding adding weight to cardiovascular exercise is MOST accurate?
The addition of light handheld weight to cardiovascular exercise may not significantly increase energy expenditure
Some research has shown that adding weight to cardiovascular exercise may not significantly increase energy expenditure. However, some cases have shown an increase in heart rate of 5-10 beats per minute and an increase in oxygen consumption of 5-15%. This is thought to be due to more active engagement of the arms while holding the weights, which increases the intensity.
Which of the following does NOT fall within the scope of practice of an ACE-certified Group Fitness Instructor?
Highlighting the weight-loss successes of class participants and asking them to talk about the particular diets that they followed
Providing information about a particular diet plan is outside of the GFI scope of practice. An ACE-certified Group Fitness Instructor may provide general healthy food tips such as ones that can be found on www.ChooseMyPlate.gov, but may not endorse a particular diet.
What are the elements that form a binding contract under basic contract law?
Offer and acceptance, consideration, legality, capacity
Whatever the nature of the work arrangement, a GFI must be aware of the essentials of contract law. Basic contract law indicates that the following elements are necessary to form a binding contract: offer and acceptance, consideration, legality, and capacity. Under these main elements, the following should also be addressed: identification of the parties, description of services, compensation, confidentiality, business status, and term.
You have been able to give more individual feedback to participants in your circuit class due to the fact that exercises have become more habitual for the participants. What stage of learning BEST describes this behavior?
During the autonomous stage of learning, skills become more automatic and fewer errors are made. Participants can perform without a leader and can detect their own mistakes.
During class, you instruct participants to begin a side plank exercise. Which muscle would you PRIMARILY be asking them to activate by cueing them to gently pull the navel in toward the spine?
The transverse abdominis muscle is activated when the navel is pulled in toward the spine.
What is the MOST important consideration when using the simple-to-complex teaching strategy?
Progressively challenging the participants
Simple-to-complex instruction is a more advanced teaching strategy that treats a sequence of movement patterns as a whole, teaching small changes or complexity in order to progressively challenge the class.
As a means of monitoring exercise intensity, a 42-year-old participant with a resting heart rate of 65 beats per minute has recently purchased a heart-rate monitor and would like to exercise at an intensity of 60-85% of his heart-rate reserve. What is his estimated target heart-rate range if you are using the following formula: Maximum heart rate = 208 - (0.7 x Age)?
Maximum heart rate (MHR) = 208 - (0.7 x Age)
MHR = 208 - (0.7 x 42)
MHR = 208 - 29.4 = ~179 bpm
Heart rate Reserve (HRR) = MHR - resting heart rate (RHR)
HRR = 179 - 65 = 114
Multiply by 60% and 85% to find the intensity range
114 x 0.60 = 68.4
114 x 0.85 = 96.9
68.4 + 65 = ~133
96.9 + 65 = ~162
Target heart-rate range of 133 - 162 bpm
Which of the following cues would result in the GREATEST increase in intensity during a basic march?
March forward, lift knees high, and alternate reaching the arms overhead
Movement incorporating large leg movements and large arm movements increases energy expenditure and therefore results in the greatest increase in intensity.
Which description of the planned choreographic method of instruction is MOST accurate?
Planned choreography falls under the structured method of teaching choreography. It often follows choreographed formats and guidelines for instructors as to what a class should include. As long as instructors follow these guidelines, they can make their own individual choices on such things as song selection and sequencing of moves.
What is the MOST appropriate activity for a participant who notifies you that he has just been prescribed a beta-blocker medication for a recent diagnosis of hypertension?
Regular exercise can create a decrease in blood pressure that may last for hours post-exercise. A semirecumbent bike is a good option since it creates a lower-intensity movement. Aerobic training is recommended three to seven days per week for 30 to 60 minutes per session with an RPE of 11 to 14. Beta-blockers can attenuate heart rate. Therefore, the RPE scale should be used for this individual. Strength training is also recommended to increase muscular fitness. This should include high repetitions and low resistance.
What is the BEST example of a comparative negligence case?
An injury during a group exercise class is due to negligence on the part of both the instructor and participant
Comparative negligence is a system used in legal defenses to distribute fault between an injured party and any defendant. Contributory negligence is a legal defense used in claims when the participant's negligence contributed to the injury.
