The Combined Influence of Blueberry and Banana Consumption on Metabolic Recovery from 75-km Cycling Exercise Stress

Principal Investigator: David C. Nieman, ASU Human Performance Laboratory at the North Carolina Research Campus, Kannapolis, NC

What is the purpose of this research?

Ingesting one or two bananas (with water) each hour during intensive cycling supports performance and decreases muscle damage, inflammation, and blood levels of stress hormones. Blueberries are high in polyphenols, a type of plant chemical that may provide added benefits for the athlete in improving recovery of various body systems following vigorous exercise bouts.

The PURPOSE of this study is to investigate the combined influence of 2-weeks blueberry ingestion (equivalent of 1 cup per day) and banana ingestion (during exercise) on performance and in improving recovery from the physiological stress of cycling 75-km at high intensity.

Why am I being invited to take part in this research?

You will be one of 60 to 70 cyclists in this study at the ASU-NCRC Human Performance Lab in Kannapolis, NC. You are being invited to take part in this research if you are a healthy male or female cyclist, ages 18 to 55 years, and regularly compete in road races and/or are capable of cycling 75 km in a laboratory setting (using own bicycles on CompuTrainer training systems).

What will I be asked to do?

The research procedures will be conducted at the Human Performance Laboratory (Room 1201, Plants for Human Health Institute Building, 600 Laureate Way), operated by Appalachian State University at the North Carolina Research Campus (NCRC) in Kannapolis, NC. You will need to come here five times, and the total amount of time you will be asked to volunteer for this study is about 10-12 hours at the Human Performance Laboratory. You will also ingest a supplement powder each day for two weeks, provide eight blood samples, engage in a 75-km cycling time trial, and keep one 3-day food record. One to two weeks prior to the start of the study, you will report to the NCRC Human Performance Lab (lab visit #1) for orientation and baseline VO2max and body fat testing. On your assigned date and time, you will return to the lab in an overnight 9-hour fasted state (lab visit #2), and provide a blood sample. You will be randomized to blueberry and placebo groups, and be given a 14-day supply of freeze-dried blueberry powder or placebo powder. The blueberry and placebo supplements will be ingested daily for 2-weeks prior to participation in the 75-km cycling time trial (lab visit #3). You will be randomized to cycle 75-km on water alone or with bananas (about one half banana every 15 minutes) and water (and this will be revealed to you after the blood draw at 7:00 am). A series of post-exercise recovery blood samples will be collected (immediately post-exercise, and then 1.5 h, 3 h, and 5 h after cycling 75 km. A meal will be provided after the 1.5 h recovery blood sample. You will return the following two mornings after the cycling bout to provide overnight fasted blood samples (lab visits #4 and #5).

Will I be paid for taking part in the research?

We will pay you $500 for the time you volunteer while being in this study.

Fructose Study

Recruiting: African American, Hispanic and Caucasian participants
30 to 50 years old. Must be free of diabetes, fructose intolerance, and chronic kidney disease
What You’ll Do: Volunteers will come to the NRI (Kannapolis, NC) for approximately 3 hours, undergo an oral fructose challenge, fill out questionnaires, provide serial blood and urine samples
Study Purpose: High uric acid in the blood increases the risk of gout, kidney and heart disease. This study investigates whether each individual responds to sugar-sweetened beverages differently, due to their differing ethnicity and genetic backgrounds.
Eligible participants will be well-compensated once the study has been completed.
Get started today. Call 704-250-5060 or email xinruo@live.unc.edu.

Fatty Liver Study

Study Purpose: To evaluate a new painless/non-invasive technique to study fatty liver disease.
Recruiting: 18 – 70 year olds with fatty liver disease.
What You’ll Do: Participants will volunteer for 2 days. Two non-invasive tests will be conducted to evaluate a known diagnosis of fatty liver disease. Each visit will take approximately 1 – 2 hours.
Eligible participants will receive $75 upon completion of each visit.
Call 704-250-5035 or email tondra_blevins@unc.edu.

Maternal and Child Health Study  

The UNC Nutrition Research Institute seeks to determine the effect of pregnancy complications in African American mothers on the disease risk of their children. Examples of pregnancy complications include high blood sugar, high blood pressure and preeclampsia.

Recruiting:

  • African American mothers
  • Must be 18 years or older
  • With two or more children between ages 5-10
  • Mothers may or may not have had pregnancy complications

Volunteers will stay 1 to 2 hours to fill out questionnaires and provide blood, saliva and urine samples. See Details

MURDOCK COPD Study

Duke University in Kannapolis announces a new study opportunity, the COPD Study. Chronic Obstructive Pulmonary Disease, or COPD, is a progressive disease that makes it hard to breathe. Smoking is the most common cause of COPD. If you have smoked, you might qualify. Researchers will study the severity of smoking-related symptoms in 850 people and follow the progression of lung function and symptoms over five years. Compensation will be offered throughout the study.

People who qualify for the COPD study:

  • Are at least 40 years old
  • May or may not have COPD or emphysema
  • Are current or former heavy smokers

The study will contact participants every six months for five years. To learn more, call 704-250-5861, email murdock-study@duke.edu or visit www.murdock-study.org/COPD.
