My name is Dr Noha Nasef and I’m a Postdoctoral Researcher in the Riddet Institute (based in Palmerston North). I’m working with my colleagues Dr Carlene Starck, Assoc Prof Ajmol Ali, Dr Toby Mundel, Assoc Prof Kay Rutherfurd-Markwick and Ms Wendy O’Brien on this study that looks at how eating certain foods may affect your health.
While exercise, prescribed as part of a healthy lifestyle, can prove protective against communicable diseases, it can also cause a ‘stress’ response. The aim of this study is to look at how consuming the antioxidant vitamin C or kiwifruit, can affect stress produced through exercise in women.
To take part in this study you must be a recreationally active healthy female with a regular menstrual cycle and with normal body weight (body mass index between 18 and 30 kg/m2) at initial assessment.
You are NOT eligible to participate if you:
Are pregnant or breast feeding
Are taking hormone supplements
Are dieting or have any eating disorders;
Have allergy or intolerance to kiwifruit;
Have a history of heart problems;
Have a history of diabetes, high blood pressure or high cholesterol;
Have history of gastrointestinal disorder, renal or liver disease;
Smoke;
Are a professional/international athlete
Participation in this research is voluntary. Only those people who have given their written informed consent will be included in this study. If you do decide to participate, you may withdraw from the project at any time without any consequence to you.
By participating, you may acquire new knowledge and contribute to the scientific advancements of nutrition and exercise. You will also receive a small koha (gift) of $10 (visit 1), $20 (Visit 1) and $30 (each visit 2-5) Westfield gift voucher.
If you agree to participate in this study, you will be invited to visit the Sport and Exercise Science Laboratory (Building 60) on the Massey University, Albany Campus 5 times.
Prior to your first visit you will be sent an online survey and asked to answer questions about your medical history and physical activity. If you are still eligible you will be invited to the lab for a screening/familiarisation visit.
During your first visit (~1 hour), we will measure your height weight and blood pressure. If eligible for the study, you will then complete a familiarisation during the same visit. You will be familiarised with the exercise program and saliva collection procedure. During this visit, we will also work out your maximum intensity on a cycle ergometer. The maximum intensity test will push you to exhaustion, and will be used to determine at what intensity you cycle during visits 2-5. You will be asked to download an app that monitors your menstrual cycle and invited for visits 2-6
Visits 3-6 are the main trial visits and will be based on your menstrual cycle (each visit will be ~1 month apart). For these visits, you will be asked to fast overnight and record a food diary. When you arrive the following morning you will be asked to provide a urine sample to test your hydration, then you will be provided with breakfast and the test product (to be consumed in 15 minutes). An hour after your meal, you will be asked to either perform the prescribed exercise (cycling at 80-85% of your maximal heart rate) or sit for 30 minutes. Saliva will be collected before you consume the meal, before the exercise and 3 times after the exercise.
Some people may find it uncomfortable to do the high intensity exercise. If you have previously experienced negative symptoms from high intensity exercise, please inform the study researcher or medical personnel.
Breakfast will include toast or cereal along with the test product (containing vitamin C or kiwifruit, sugar, water and food colouring).
Saliva will be collected to assess markers of stress, immunity and oxidation. Any unused saliva samples will be disposed of following standard bio-hazardous waste procedures.
Results of this research will be published in scientific journals. Individual participants will not be identified in any report arising from the project.
Your information will be treated with the same respect for privacy and confidentiality as is undertaken for all medical information collected about you during your visits to your local doctor. Access to the collected information will be limited to the named investigators only.
All information collected from participants will be stored in the original paper copy in a locked filing cabinet at the Sport and Exercise Science Laboratory accessible only to the investigators. Data will only be identifiable by a participant identification number with no other identifying details on file. During statistical data analysis the database will be stored in a password protected computer file.
All data for the study will be kept by the Chief Investigator for the period of 5 years following the completion of the study. Only the investigators conducting this research will have access to this information.
Feedback of results from the investigation and other information regarding the outcome of the research will be made available to you and will be posted as an individual letter at the completion of the study.
You are under no obligation to accept this invitation. If you decide to participate, you have the right to:

If physical injury results from your participation in this study, you should visit a treatment provider to make a claim to ACC as soon as possible. ACC cover and entitlements are not automatic and your claim will be assessed by ACC in accordance with the Accident Compensation Act 2001. If your claim is accepted, ACC must inform you of your entitlements, and must help you access those entitlements. Entitlements may include, but not be limited to, treatment costs, travel costs for rehabilitation, loss of earnings, and/or lump sum for permanent impairment. Compensation for mental trauma may also be included, but only if this is incurred as a result of physical injury.
If your ACC claim is not accepted you should immediately contact the researcher. The researcher will initiate processes to ensure you receive compensation equivalent to that to which you would have been entitled had ACC accepted your claim.
