DOMAIN FOUR /SPECIAL POPULATIONS

Developing personal training skills to work with special populations is essential. Special populations are

now one of the fastest growing segments of the personal training industry. Gathering and understanding

client’s medical considerations and collaborating with their healthcare providers to discuss their needs

is a necessary part of the job. Understanding signs and symptoms of distress and making sure exercise

guidelines are appropriate are critical. Being able to develop safe and effective programs for your clients

with special considerations can truly enhance the physical, mental, and emotional wellbeing of your client.

This will leave a lasting effect on health and wellness.

LIFESPAN CONDITIONS These can be considered populations that require different attention based on a life situation, rather than

an acquired condition.

OLDER ADULTS Aging affects the function of all body systems. This can include things like decreases in hormone

production; elasticity diminishment in muscles, skin, and blood vessels; and deterioration. Although all

systems are affected, physical activity can slow it considerably. Recovery time becomes an important

consideration when working with older adults. Fitness professionals should consider the following:

• Most adults 55 and older will experience decreased ROM, with limitations more pronounced at 70

years and older

• Once adults reach 65, programs should be based on and modified from medical recommendations

• Closely monitor signs of fatigue, muscle weakness, and joint pain in clients 65+

• Low exertion levels with close monitoring and a focus on overall posture improvement, strength

increases, and injury avoidance are especially important for clients 80+

• There are many contraindications such as:

° Coronary heart disease - most serious form of heart disease (obstruction of blood supply to

the heart)

° Uncontrolled hypertension - arterioles stay constricted, driving pressure in blood vessels up

° Myocarditis - inflammation of the heart muscle

° Thrombosis - clotting of blood in a part of the circulatory system

YOUTH CLIENTS Fitness professionals will also have youth clients. In youth clients, the most important goals to focus on and

consider are form and technique. Further, neurological factors, rather than hypertrophic factors, are primarily

responsible for strength and resistance training gains.

• Youth clients can be conceptualized into two groups, Category 1 and Category 2. Regardless of

category, trainers should be most mindful of intensity when designing a program for youth clients.

° When training Category 1 clients (5 – 12 years), training at too high an intensity or duration

is contraindicated. Further, training in hotter or more humid climates is cautioned because

their thermoregulatory mechanisms aren’t fully developed.

° When training Category 2 clients (12 – 17 years), be cautious of tendinous injuries, Osgood

Schlatters (inflammation of the patellar ligament at the tibial tuberosity and presents as a

painful lump below the knee), low initial fitness levels, excess body weight, and

musculoskeletal disorders.

° When training children, it’s important to remember that:

° Children aren’t miniature adults.

° Children are susceptible to heat exhaustion and heat stroke.

° Children are susceptible to cold injuries.

° Children are particularly vulnerable to Osgood Schlatters disease (contraindication

for Category 2 youth clients)

PRENATAL For a pregnant woman and her fetus, sensible exercise can be a safe undertaking. When working with

pregnant clients, the following conditions should preclude the expecting mother from exercising:

• Coronary heart disease

• Ruptured membranes

• Premature labor

• Placenta previa

• Incompetent cervix

• Vaginal bleeding

• History of three or more spontaneous abortions or miscarriages

However, the trainer should be ready to consult the doctor at any unexplained contraindication. For example,

a pregnant client experiences persistent severe headaches and unexplained spells of dizziness. In this

situation, you should immediately have her discontinue the training session or program and immediately

consult with her doctor.

ADAPTIVE FITNESS Whether at the onset of birth or through life conditions clients might present with a handicap, disability, or

impairment. When working with these clients, you must get medical clearance first. It’s important to know

these terms:

• A handicap is a circumstance that makes progress or success difficult.

• A disability is a physical or mental condition that limits an individual’s movements, senses, or

activities. With the adoption of the Americans with Disabilities Act, there’s the protection of rights

for people with disabilities to include equal employment opportunities, rights to purchase goods and

services, and participation in state and local government programs and services. This means all

public gyms must be accessible for wheelchair users.

• An impairment is the state of being impaired, especially in a specified facility.

With an adaptive fitness program, the overall goal should be improved fitness, mobility, and self-efficacy. And

although these programs can be enjoyed by anyone with a disability, fitness professionals should specifically

consider orthopedic and joint dysfunctions. To be an effective fitness teacher and professional, one must

adapt, modify, and create until the client is successful. Finally, true education in adaptive fitness programs

implies full involvement of the mind and body.

CHRONIC CONDITIONS Certain conditions will present themselves as part of lifestyle or acquired over time and pervasive. These

types of diagnoses are considered chronic conditions, and you should be familiar with common types you’ll

likely encounter.

HYPERTENSION Hypertension is a medical condition of a chronically elevated level of arterial pressure. Readings as low

as 140/90 are considered the threshold for high blood pressure by some authorities. When working with

clients who are hypertensive, it’s critical to get medical clearance first.

• There’s a number of ways individuals can prevent hypertension, they include:

° Maintaining healthy bodyweight

° Limiting alcohol intake

° Not smoking

° Moderating the amount of salt in the diet

° Consuming adequate amounts of calcium

° Exercising on a regular basis

• Program design recommendations for hypertensive clients (especially beginners) are:

° Non-weight-bearing or low-impact aerobic activities

° Low intensity (50% to 75% MHR)

° Exercise duration 20 – 30 minutes, four times per week

° Prolonged warm-up and extended cool down

° RPE to monitor intensity

DIABETES When blood sugar levels increase, the pancreas produces insulin, which regulates many metabolic

processes. Diabetic bodies either do not produce enough insulin or cannot properly use the insulin it

makes. Diabetes also increases the risk of:

• Heart disease - conditions that involve narrowed or blocked blood vessels

• Stroke - blood supply to part of the brain is reduced, depriving brain of oxygen/nutrients

• Gangrene - localized death and decomposition of body tissue from obstructed circulation or bacterial

infection

• Kidney disease - kidneys become damaged and can no longer filter blood and wastes properly

• Retinopathy - serious eye disorder resulting from diabetes complications

When designing a program for a diabetic client, it’s important to know the type (category) and severity of the

diabetes.

• Type I diabetics can exercise at an intensity level similar to a healthy adult, 55 – 85% MHR, whereas

Type II should be advised to exercise on the lower end of the range.

• Type I diabetics should exercise 20 – 30 minutes per session and Type II should exercise for a

longer duration, 40 – 60 minutes per session.

• When accompanied by obesity, Type II diabetics should primarily perform low impact, non-weight

bearing activities with the intensity 55 – 85% of MHR in moderation.

• When working with diabetics on a nutrition plan, it’s imperative that a personal trainer refer them to

a dietitian.

ARTHRITIS This is a common condition that’s caused by pain or stiffness in skeletal joints is arthritis. In some

instances, the cause of arthritis is known as an injury to the joints, an infection like Lyme disease, the

product of medication, etc. In other instances, the cause might be hereditary, food allergies, nervous system

malfunction, and an attack on the immune system. Body temperature is key to safe and effective workouts;

therefore, warm showers, saunas, and extended warm-ups and cool downs are important.

CORONARY HEART DISEASE Obesity and stress are confirmed risk factors for coronary heart disease (CHD); however, exercise has

been shown to help control both obesity and stress. Coronary artery disease is the narrowing and even

blockage of the arteries and blood vessels that provide oxygen and nutrients to the heart. Sometimes called

atherosclerosis, CHD can sometimes go without symptoms but the number one sign of this condition is

anginal chest pain.

High impact activities will not be suitable for this population during early stages of programming and heart

rates should be carefully monitored.

ASTHMA A tightening of the airways in the lung, known as asthma, results from either undue inflammation of the

lining of the airways or specific triggering factors. Environmental considerations are key for this population

and include pollen, allergies, smoke, extreme temperatures, and chemicals.
