Background

Importance of optimal athlete nutrient

intake

Impact of muscle cramps for athletes

Malnutrition present on collegecampuses

Banana consumption

ObjectiveWho?At least 100 NCAA college athletes

(ages18-25)Why?

Athlete nutrient intake is a major factor on

the level of performance. Determining the

biological benefit of consuming bananas on

muscle cramps will allow athletes to improve

their athletic performance.


5/19

n ro uc on-

HypothesisAn increased intake of potassium byway of banana consumption will cause

an overall decrease in the frequencyand prevalence of exercise induced

muscle cramping, while

increasing blood potassiumlevels.

Materials1. Survey Study

2. Longitudinal Study

3. Statistical Analysis


7/19

1. Survey Study

At least 100 subjects (Male/Female)

College NCAA Athletes (ages 18-25) Currently experience at least three muscle cramps per

month

Individuals who are currently not taking medication for

diabetes or oral contraceptives

The surveys will be analyzed and collected aft

er six months.

1. Survey Study

The survey will include:Gender

Age

Body mass index via weight and height

Type and length of physical activity

Current consumption of bananas and potassium

rich foodsCurrent frequency of muscle cramping

Current intake of diabetes medications and oral

contraceptives

1. Survey Study The survey will be given to the

athletic departments at fiveuniversities located inCalifornia:

University of California LosAngelesUniversity of California Berkeley

San Diego State UniversityUniversity of Southern CaliforniaStanford University


11/19

1. Survey Study

The inclusion factors

(male and female NCAA athletes, at least

three muscle cramps per month, nottaking oral contraceptives or diabetes

medication )

The aim(acquire at least one hundred participants)


12/19


After determining the final number of

participants

Body mass indexes calculated

Blood pressure

A week long food record + 24 recall

Initial Blood potassium levels measured

Current potassium intake, specifically banana

consumption


13/19


The study will be broken down into two twelve

week segments

The first 12 week segment

normal dietary consumptionfood records

documentary of any episodes of exercise

induced muscle cramps initial Blood potassium levels


14/19


The second 12 week segment

Five servings of banana per week (150g=

1 full serving)

Food recordsDocumentary of any episodes of exercise

induced muscle cramps

Blood potassium levels will be measured

everytwo weeks

Data will be analyzed to determine anyrelationship between potassium consumption

and the effects on exercise induced muscle
