Exercise
ACE Group Fitness Instructor Manual
1) Which of the following is NOT a common symptom associated with an acute injury to a ligament
caused by sudden trauma to a joint?
A.
B.
C.
D.
Pain
Localized Swelling
An open wound
Joint instability
Explanation
C. An open wound
A sprain refers to an acute injury to a ligament caused by sudden trauma to the joint. Sprains can occur
at any joint, but are most common at the ankle and knee. Damage can vary from stretched ligaments to
complete tears. Sprains are rated in degrees: 1st degree (mild), 2 nd degree (moderate), and 3rd degree
(severe). Symptoms of sprains include pain, localized swelling, discoloration, loss of motion, loss of use,
and joint instability.

2) Which of the following is the MOST appropriate consideration for a Group Fitness Instructor to make
for a class participant with a strain?
A. Always move the effected joint through a full range of motion
B. Gradually increase the intensity of activity
C. Use ballistic exercises during the warm-up phase of the class.
D. Minimize additional stretching before and after class.
Explanation
C. Gradually increase the intensity of activity
A strain, often called a muscle “pull,” is an injury to a muscle, usually caused by overexertion.
Strains can be acute, occurring suddenly during activity, or can gradually develop from repeated overuse.
Symptoms of a muscle strain are pain, loss of motion, and reduced strength.
Strains: Considerations for Group Exercise
• Avoid introducing strenuous or ballistic exercise after a participant experiences a muscle strain until the symptoms
are minimal or no longer present.
• Gradually increase the intensity of activity.
• Incorporate additional gentle stretching of the muscle before and after exercise.
• Confine movement to the pain-free range of motion (ROM).
• Monitor the participant for a return of symptoms or an increase in their severity resulting from the activity.

3) A participant presents you with a note from her doctor stating that she should “avoid deep squats,
cutting movements, pivoting, or twisting” for as long as she is symptomatic. From what type of injury is
she MOST likely recovering?
A. Plantar fasciitis
B. Stress fracture
C. Cartilage damage
D. Hip bursitis
Explanation
C. Cartilage damage
Among the considerations for group exercise for individuals who are recovering from cartilage damage
is that they should avoid deep squats, cutting, pivoting, or twisting for as long as symptoms are present.

4) What is the final phase in a tissue’s reaction to healing?
A.
B.
C.
D.
Inflammation
Fibroblastic
Proliferation
Remodeling
Explanation
D. Remodeling
When an injury occurs, the healing process begins immediately. The body goes through a systematic
progression with three distinct phases: the inflammatory phase, which can last for up to six days; the
fibroblastic/proliferation phase, which begins approximately at day 3 and lasts approximately until day
21; and the maturation/remodeling phase, which begins at day 21 and can last for up to two years.

5) Which of the following is NOT a sign or symptom of tissue inflammation?
A.
B.
C.
D.
Swelling
Warmth
Loss of function
Cool and clammy
Explanation
D. Cool and clammy
When the tissues of the body (e.g. Muscles, tendons, and ligaments) become inflamed, they will elicit
specific signs and symptoms of which the GFI needs to be aware. This is particularly important for
participants who are post-injury or postsurgery. The goal is to give these individuals a challenging
exercise routine that will not cause further damage to the injured area. The signs and symptoms of tissue
Inflammation are as follows
• Pain
• Redness
• Swelling
• Warmth
• Loss of function

6) Which of the following is NOT among the on-the-spot indicators that a group fitness instructor can
use to gauge potential participants’ limitations in a group setting?
A.
B.
C.
D.
Gender
Age
Posture
New participation
Explanation
A. Gender
There are three on-the-spot indicators that can be used to gauge potential participants’ limitations and
alert the instructor to the type of exercise modifications he or she may need to provide during the class.
These indicators are age, posture, and new participation.

7) Improper footwear and exercise surface are MOST associated with which lower-extremity injury?
A.
B.
C.
D.
Plantar fasciitis
Shin splints
Achilles tendinitis
Infrapatellar tendinitis
Explanation
B. Shin splints
Footwear and exercise surface are major factors in the onset of shin splints.

8) Which of the following statements about the management of low-back pain is MOST accurate?
A.
B.
C.
D.
Only perform 1 to 2 repetitions of exercises that cause pain.
Emphasize the maintenance of good posture
Minimize stretching of the trunk and lower extremities
Engaging the abdominal muscles for protection of the lumbar spine is not recommended.
Explanation
B. Emphasize the maintenance of good posture. Poor posture can cause low back strains and sprains, as
well as potentially damage the discs and bony structures. Good postural alignment means that the head
is aligned so that the ears are over the shoulders. The shoulders should be pulled back to align with the
hips. The back is slightly curved forward at the lumbar region, with the top of the pelvis parallel to the
ground. Excessive lumbar or thoracic curvature indicates poor posture and high risk of low-back
problems

9) Which of the following statements about appropriate record keeping following an in-class injury is
MOST accurate?
A.
B.
C.
D.
The incident report should be posted in the facility for a minimum of two weeks.
The incident report should be completed by facility management or ownership.
The identification of witnesses should not be included on the form for confidentiality reasons.
The incident report should be completed immediately after the event.
Explanation
D. The incident report should be completed immediately after the event.
The incident report should be filled out immediately after the event and with as much detail as possible.
It should be completed by the staff member who was most directly involved and witness names and
contact information should be included. For confidentiality reasons, the report should be filed securely,
and never posted for others to see.
