Half Marathon Runner – Recreational Adult

Sally Brown, a 35-year-old female runner, was referred to your personal training studio by one of your clients. She has been struggling with IT band syndrome for 3 months and was diagnosed by her orthopedic specialist, Dr. Miller. She hopes to get back to enjoying running without pain. Dr. Miller prescribed prescription strength ibuprofen and specific stretches and exercises. She also recommended that she reduce her running mileage and incorporate cross-training. She scheduled a 1-month follow-up in which she will re-evaluate and determine whether physical therapy or additional medical treatment is needed.

She has a goal to complete the Dallas half-marathon this December. She is currently running 6 miles/week (2 miles, 3 days/week) and is struggling to build her mileage due to her left lateral knee pain that starts after about 1 mile of running. She was running 20 miles/week before her knee pain started. She describes the pain as sharp and stabbing when it starts but it gradually goes away when she stops.

She does not train with a heart rate monitor and runs based on “feel”, which is a moderate to hard effort level on every session. She has never been through any baseline data tests. Her typical pace is 9:30 min./mile. She does not do any resistance training or foam rolling but stretches occasionally before her runs.

Clinical Correlation - IT Band Syndrome

Common knee injury caused by inflammation of the distal aspect of the iliotibial band OR a pathological bursa between the IT band and femoral condyle

Characterized by a sharp, burning pain approx. 2 cm proximal to the lateral femoral condyle

22.2% of all lower extremity injuries in runners

Management of IT Band Syndrome

Conservative – shown to be 44% effective at 8 weeks and 91.7% effective at 6 months for successful return to sport

Massage

Manual therapy – Graston, ART, joint mobilization

Active care – foam rolling, stretching, rehab

Modification of running habits – reduce volume & intensity

Prescription pain relieving ointment (voltaren gel)

Anti-inflammatory medication (ibuprofen, aleve, naproxen)

Corticosteroid injection

Surgical – should only be considered for chronic cases unresponsive to conservative treatment

Release of IT band from its insertion point with debridement

Professional Rower – Lab 3

24-year-old elite rower hoping to qualify for the Olympic games. You have recently been hired as a strength and conditioning consultant for the US Rowing team and the coach is asking that you put together a resistance training program for this athlete to build strength and power. He has an exceptional aerobic capacity but needs to work on his final 500m sprint during the 2000m individual scull event. He does not have any pain or injuries. His current training program consists of full body exercises involving barbells, machines, and calisthenics.

Polarized Training

“Easy” does not necessarily equate to the ACSM “light” intensity range of 20 – 39% HR reserve! Easy refers to rating of perceived exertion (RPE).

According to the 3-zone training model, this is a minimum of 50% VO2max, which would be in the ACSM “moderate” range of 40 – 59% HR reserve

The upper end of the green zone is approximately 75% HR max, which equates to a slightly lower HR reserve (there is some individual variance), but approximately 65% HR reserve.

Do not confuse the ACSM “vigorous” intensity range as “hard” training!

This is a broad range (60-89% HR reserve) with significant variation in RPE

The low-end of this range (60 – 70% HR reserve) is typically not hard to sustain for trained, healthy adults!

Need to account for individual variation in the fitness level in your clients

Polarized Training Model

Zone 1

Beta Oxidation

LT1 = 1st lactate turn point; known as the “aerobic threshold”

Low cardiovascular and metabolic stress

< 2 mm blood lactate

Type 1 muscle fibers

Zone 2

Primarily slow glycolysis and beta oxidation; lower contribution of fast glycolysis

LT2 = 2nd lactate turn point (i.e., lactate threshold, maximal lactate steady state, or anaerobic threshold)

2 – 4 mm blood lactate

Type 1 and Type 2a muscle fibers

Zone 3

Fast and slow glycolysis

High cardiovascular and metabolic stress

> 4 mm blood lactate

Type 1, Type 2a, and Type 2x muscle fibers

Relative Intensity

For the average healthy adult, exercise intensity must be at least 50% of HRR OR 70% max HR!

Application of the Fick Equation

Volume of O2 (ml/kg/min.) = cardiac output (L/min) x arteriovenous oxygen difference (ml O2/100 ml blood)

VO2 = Q x a-vO2 diff

Central adaptations are acquired primarily through high-intensity aerobic training

Peripheral adaptations can be acquired through continous aerobic training under LT1!

Important to enhance both the pumping capacity of the heart and oxygen extraction capacity of the skeletal muscles for greatest gains in aerobic fitness!
