Where and how does gas exchange occur between the outside air and the bloodstream?
Alveoli and diffusion
Capillaries and osmosis
Capillaries and diffusion
Alveoli and active transport
Alveoli and osmosis
Alveoli and diffusion: is the correct answer.
During respiration air is drawn through the upper respiratory tract and down the brachii and bronchioles tract before finally reaching the alveoli.
At this structure gas echange occurs between the outside air in the lungs and the bloodstream through diffusion [transfer through pressure gradients].
Alveoli and osmosis: is incorrect.
The location is correct, but gas does not travel via osmosis, water does.
Capillaries and diffusion: is incorrect
Gas is exchanged between the bloodstream and cells at the capillaries and diffusion, not the bloodstream and outside air.
Capillaries and osmosis: is incorrect
Gas is not exchanged between the bloodstream and outside air in the capillaries and gas is not exchanged via osmosis.
Alveoli and active transport: is incorrect
Gas is exchanged between the bloodstream and outside air at the alveoli, but gas exchanged via diffusion is a passive not active process.
A client with misaligned joints due to poor posture is unable to develop maximal tension during an exercise. What phenomenon may explain this situation?
Length-tension relationship
All or none principle
Force-couple relationship
Force-velocity curve
Newton’s first law
Length-tension relationship:
is correct as it describes an optimal muscle length at which the potential for actin and myosin binding is greatest.
When the joints are misaligned, the muscle may not be able to reach its optimal length.
Either the muscle is shortened and the actin and myosin is already in maximum overlap and no further movement between the filaments can occur, or it is lengthened and the overlap is significantly reduced.
All or none principle: discribes the phenomenon in which all of the muscle fibers of the motor unit will contract or none of them will. This phenomenon is not related to posture any way and is incorrect.
Force-couple relationship is synergistic actions of muscles that surround a joint to produce movement. This relationship is dependant on the structure of the joint and the pull of the muscles, not positions of them and is therefore incorrect.
Newton’s first law states that an object will stay at rest or motion unless acted upon by an external force. This does not relate to posture and the ability to produce force within a muscle and is incorrect.
Force-velocity curve shows an inverse relationship between muscle contraction speed and the maximum force that can be produced at that speed. This relationship does not take into account joint positions and makes this answer incorrect.
Which of the following is the most essential for fat loss to occur?
Caloric deficit
Increased protein intake
Decreased fat intake
Increased vegetable consumption
Smaller, more frequent meals
Caloric deficit:
is correct because this would require body fat to fuel the extra energy needs.
Helping clients lose weight is a complex issue that has many physiological, psychological, emotional and social components.
Most studies have show that the best long term results have come from combining a consistent exercise program with a moderate daily caloric deficit.
Decreased fat intake: is incorrect because this may not necessarily result in a caloric deficit.
Increased vegetable consumption: is incorrect because this may not necessarily result in a caloric deficit.
Smaller, more frequent meals: is incorrect because this may not necessarily result in a caloric deficit.
Increased protein intake: is incorrect because this may not necessarily result in a caloric deficit.
A client has a average daily energy expenditure of 2,500 calories. What must his daily caloric intake be in order to lose 10 pounds over the next five weeks?
1,7500 Calories
2,250 Calories
1,000 Calories
1,500 Calories
2,000 Calories
1,500 calories:
is correct because a total caloric deficit of 3,500 calories must occur to lose one pound of fat.
To lose 10 pounds, a total caloric deficit of 35,000 calories is needed over 5 weeks, or 35 days.
Therefore a daily caloric deficit of 1,000 calories is needed. Indicating that this client must consume approximately 1,500 calories per day for this weight loss to occur.
1,000 Calories: is incorrect because this is the deficit that is needed, not the intake.
2,000 Calories: is incorrect because this intake would result in half of the fat loss goal.
2,250 Calories: is incorrect because this intake would result in a quarter of the fat loss goal.
1,750 calories: is incorrect because this caloric intake is too high.
Which biomechanical response occurs during the gait of a client who has sprained their ankle?
Hip hike to account for affected limb
Stance phase of two limbs are not equal
Exaggerated knee and hip flexion of unaffected limb
Pelvis is lateraly rotated
Weight bearing on lateral edge of foot
Stance phase of two limbs are not equal:
is correct because stance is much shorter duration on affected side affect due to the pain.
The swing phases will be unequal as well.
Normal walking gait includes both a stance and a swing phase that each other.
Hip hike to account for affected limb: is incorrect because this is observed in those with leg length discrepancies.
Pelvis is lateraly rotated: is incorrect: is incorrect because this is a symptom of inadequate dorsiflexion.
Exaggerated knee and hip flexion of unaffected limb: is incorrect because this often occurs with a leg length differenc.
Weight bearing on lateral edge of foot: is incorrect: is incorrect because this is a symptom of inadequate dorsiflexion.
During the upward phase of the squat, which movement of the knee and hip is taking place?
Extension
Flexion
Abduction
Adduction
Internal rotation
Extension:
is correct as this is a sagittal plane movement in that it results in an increase in the joint angle.
As the body moves upward during a squat, the joint angles of the knee and hip increase, thus producing extension.
Flexion: is incorrect as this is a sagittal plane movement in that it results in an decrease in the joint angle. The upward motion of a squat is an increase in the hip and knee joint angle.
Abduction: is incorrect because it is a frontal plane movement. Squat involves sagittal movement of the hip and knee.
The frontal plane movement of adduction is incorrect. Squat involves sagittal movement of the hip and knee.
Internal rotation: is incorrect. This movement occurs in the transverse plane and the knee and hip move in the sagittal plane during a squat.
Which of the following foods has the highes glycemic index?
Beef
Bread
Carrot
Yogurt
Chickpea
Bread:
A personal trainer can use which of the following strategies to help improve a client’s self-efficacy?
Isolate oneself
None of these
Provide distractions
Indentify barriers
Acess social support
Acess social support:
is correct because this will increase the aid and assistance of others to reach a client’s goals.
Other strategies to improve self-efficacy are to teach clients to over come barriers and regulate exercise behavior.
These will also improve motivation and self-worth.
Identify barriers: is incorrect because these barriers must be overcome as well.
Isolate oneself: is incorrect because accessing social support is more likely to improve self-efficacy.
Provide distractions: is incorrect because removing distractions is more effective.
Performing push-ups, lunges, sit-ups, biceps curls and triceps push-downs alternatively with small rest periods is an example of which type of training?
Circuit training
Mechanical training
Spot training
Power training
Flexibility training
Circuit:
is correct because this is characterized by alternating upper and lower body exercises and are performed with minimal intervening rest periods.
This method is also used when the goal is to improve cardiorespiratory endurance.
However, it is not used for that pupose as frequently as conventional aerobic exercise training.
Power training: is incorrect because this typically involves Olympic or other explosive lifts or plyometric exercise.
Michanical training: is incorrect because this type of training is not associated with exercise.
Spot training: is incorrect because this is not a type of exercise training.
Flexibility training: is incorrect because these are not flexibility exercises.
What action could lead to a ACSM personal trainer having their certification revoked?
Not practicing as a personal trainer
Obtaining another certification
All of these
Failing to attract any clients
Conduct that goes against set principles
Conduct that goes against set principles:
is correct because this is a direct violation of the mission of the ACSM.
This decision would be made by the executive council of the ACSM committee on certification and registry boards.
Ensuring that every personal trainer is aware of the principles of the ACSM and provide best practices is imperative.
Failing to attract any clients: is incorrect because this is not a violation of ethics.
Not practicing as a personal trainer: is incorrect because this is not against the ACSM’s principles.
Obtaining another certification: is incorrect because this is a form of continuing education.
All of these: is incorrect because most of the answers would not lead to having a certification revoked.
Where can a personal trainer train potential clients?
In a client’s home
All of these
Private fitness facility
Commercial fitness facility
Outdoors
All of these:
is correct because an individual with adequate knowledge and personal skills can make a living in any fitness setting.
Where the exercise takes place is not as important as the ability to attract clients and get them great results while maintaining a customer-centered mindset.
Commercial fitness facility: is incorrect because, although this is an appropriate place to train clients, a good personal trainer can apply their services anywhere.
Outdoors: is incorrect because, although this is an appropriate place to train clients, a good personal trainer can apply their services anywhere.
In a client’s home: is incorrect because, although this is an appropriate place to train clients, a good personal trainer can apply their services anywhere.
Private fitness facility: is incorrect because, although this is an appropriate place to train clients, a good personal trainer can apply their services anywhere.
What is the first step during the selection process of hiring a personal training team as a manager?
Comparing resumes to job description
Interview candidates
Conduct role playing situations with the candidates
A team interview with the candidate
None of these
Comparing resumes to job description:
is correct because this allows ranking of the candidates compared to the hiring model.
Performing this step will help limit the number of candidates to graduated to the interview step of the selection process.
It is recommended that multiple interviews occur to select a final candidate.
Interview candidates: is incorrect because this is the second step of the hiring process.
Conduct role playing situations with the candidates: is incorrect because this should occur during the second interview.
A team interview with the candidate: is incorrect because this should occur during the third interview.
None of these: is incorrect because comparing resumes is the correct answer.
Which of the following should not be included in the resume when applying for a personal trainer position?
Important and relevant skills
Family members as references
All relevant work experience
Formal education and certifications and continuing education courses
Correct spelling and grammar
Family members as references:
is correct because this is unprofessional and does not indicate being valued by others.
A resume is a selling tool that outlines a fitness professional’s education, skills and experience.
Former managers, supervisors, mentors and college professors are more appropriate references.
Correct spellig and grammar: is incorrect because this would indicate intelligence and attention to detail.
All relevant work experience: is incorrect because this indicates acquire skills.
Formal education and certifications and continuing education courses: is incorrect because this demonstrates relevant knowledge.
Important and relevant skills: is incorrect because this indicates the ability to perform the task.
In a fitness facility, who must be certified in CPR and AED use?
Management only
Any staff responsible for working directly with exercise participants
At least half of the personal trainers
Facility owner only
Every staff member
Any staff responsible for working directly with exercise participants:
is correct because this will keep any individual who may require these emergency procedures close to those who can help.
As evidence of professional competency, personal trainers should keep CPR, first aid and AED certifications current.
Personal trainers shoud proactively familiarize themselves with any affiliated organizations emergency plan and be ready to impement the plans procedures in case of emergency.
Every staff member: is incorrect because it is not mandatory for those who don’t train clients to have these certifications.
Management only: is incorrect because these individuals are not always readily available to a client who need an emergency procedure.
At least half of the personal trainers: is inocorrect because every personal trainer should be certified.
Facility owner: is incorrect because this individual is not always on the premises.
What is the recommended amount of personal liability insurance a trainer should carry at all times?
5 million
2 hundred thousand
1 million
2 million
3 million
2 million:
is correct because this provides enough extra protection should a lawsuit or insurance claim be made.
Personal liability insurance will protect assets of a personal trainer.
The ACSM recommends that a personal trainer should carry their own insurance even if health facility cover them.
1 million: is incorrect because this may not be enough protection if a lawsuit or insurance claim is made.
5 million: is incorrect because this more than likely needed when facing a lawsuit or insurance claim.
3 million: is incorrect because this is slightly more than what is needed.
2 hundred thousand: is incorrect because this is much less than what is needed to protect oneself.
