Predictors of Marathon Performance Aaron Palya, BS MS Kinesiology Program

Overview • • • • • Marathon-The Basics What are the key predictors?

• • • VO 2 Max (Oxygen Uptake) Running Economy Lactate Threshold Resources Claws Vs. Paws Future Talks

Marathon-The Basics • • 26.2 miles Upcoming Marathons: • Lakefront Marathon: October 5 th • • • Chicago Marathon: October 12 th Green Bay Marathon: May 18 th Madison Marathon: November 9 th Source:www.runningusa.org/statistics

What Predictors Tell Us • • • • • Indication of performance capability Measure of fitness level Help shape training runs • What pace/HR for each run Improvement is possible Estimate of Race Pace • If done close to race day

The Key Predictors • • • Maximal Oxygen Uptake (VO 2 – Measured via treadmill Max) Running Economy – Run types/components – Posture and form Lactate Threshold – Race Pace

VO 2 Max • • • Maximal amount of oxygen our bodies can use during exercise Measure of aerobic fitness Increases with training Source: www.sport-fitness-advisor.com/VO2max.html

• Influences: – Heat – Dehydration – Lactate Build-Up – Supplementation – Diet – Muscle Glycogen VO 2 Max

Running Economy • • Considered to be your running “pace” • Energy cost of running at a certain speed Improvement: • Using different runs » » Interval Tempo » Repetiti on • • Footwear Plyometrics

Running Economy (cont.) • Influences: • Biomechanics • Posture • % VO 2 Max

Lactate Threshold • • During exercise, the body accumulates lactic acid • Running just below LT=lactate does not accumulate • Higher LT=faster race pace Fatigue • Graph
