At the end of this presentation you

will be able to…

1. Explain the importance of muscle

throughout a lifespan

2. Identify what types of exercise will

lead to growth in muscle mass and

the nutrients required to maintain

and preserve it

Why is it important?

• Better quality of life

• Decreased risk of falls

• More independence

• Better recovery from injuries

and surgeries

• Better quality of Life

• Improved insulin resistance5

Long Term Short Term

What is lean body mass?Or Fat free mass includes bone, water, blood, and non-adipose tissues.

Sarcopenia

The natural loss of muscle over time

due to senescence

Within Dietetics

Nutrition Focused Physical Exam

Scenario 1Victor

26 yo male

Works out every morning before work. He loves lifting weights and tracked a gain of 12 lbs of muscle using a BOD POD over the

past 3 years. One morning he does not have time to eat his typical breakfast of eggs toast and a banana after his workout. Instead he grabs a muffin on the way to work. He feels ok the rest of that day, but during his workout the next morning he

was not able to lift what he normally does. The day after that it gets even worse. He is plagued by DOMS for the rest of that

week.

What nutrition strategies does he need to implement to prevent this from happening again?

Interventions• Consume protein/carb source within one hour of intense

physical activity

• His typical Eggs/Toast/Banana combo

OR

• In a hurry Milk/Protein shake

• Carb - Protein Ratio 6

• 3-1 or 4-1

• Branched Chain Amino Acids

Scenario 2Maria

What might help her have more energy?

What would you do about her back?

Interventions• Increased calories to fuel activity

• Refer to Physical Therapist

Obtaining LBMWith Exercise

With Nutrition• Protein: the building block of
