The 2Before Study

Can blackcurrant juice and caffeine help sports performance?

We are conducting a study examining whether blackcurrant juice and caffeine intake can enhance exercise performance.
Blackcurrant contains high levels of anthocyanins which have been shown to reduce cell damage, reduce inflammation and enhance blood flow.
Caffeine is one of the most widely used psychoactive drugs in the world due to its accessibility, evidenced ergogenic effects and few negative side effects.
Both blackcurrant and caffeine seem to afford greater benefits to athletes when they are in a fatigued state; therefore, it would be reasonable to assume that adding caffeine to a blackcurrant beverage will provide greater performance benefit.

Who are we looking for?
- males
- aged 18-45 years
- well trained (regular training for high-intensity team sports like football, rugby and hockey)

The Vitality Study

The Vitality study aims to assess if a regular milk naturally high in protein or a high protein drink:
1) is nice to drink (acceptable based on taste, smell and creaminess)
2) if these milks can improve your general health, physical performance such as your walking speed and your muscle strength (handgrip).
As we age, muscle mass reduces. These drinks are high in protein. Increasing dietary protein with the accompanying vitamins and minerals from the milk may improve muscle strength and physical function.

Who are we looking for?
- women
- aged between 65 and 80 years old
- normal weight (BMI of 25 or less)

Unfortunately you cannot take part if you:
- have a milk allergy or are lactose intolerant
- are not a regular milk drinker
- regularly drink protein supplements
- have severe malnutrition
- have been diagnosed with diabetes mellitus
- have been diagnosed with any endocrine disease

The Effects of Online Exercise Prescription on Blood Pressure and Cardiorespiratory Fitness in Individuals

Engagement in regular physical activity promotes a healthier lifestyle and has also been associated with reducing the progression of prehypertension, thus, limiting the development of hypertension.

Incorporating a telehealth approach to exercise prescription and delivery may improve accessibility to exercise, and the rate in which individuals are physically active.

The aims of this study are to explore the effects of online exercise prescription on blood pressure and cardiorespiratory fitness in prehypertensive individuals and understand how they view this method of health delivery.

Who are we looking for?
- Aged 30 or above
- Blood pressure of 110-139/70-89 mm Hg
- Not on blood pressure medication or pregnant
- Capable of being physically active on a weekly basis

CaffcoSleep Study

The Effects of Caffeine Consumption on Sleep Quality in Healthy New Zealand Young Adults

Caffeine is the most widely consumed psychostimulant drug in the world, and it is commonly used as a fatigue countermeasure. However, its use is often associated with increased sleep disturbances, lengthened onset of sleep, reduced total sleep time and slow wave (deep) sleep, reduced sleep quality, and increased daytime sleepiness.  Sleep is important for optimal health and waking function, and young adulthood is a critical period for health and the establishment of health-related behaviours. Little research has evaluated the impact of caffeine on sleep quality, and compared objective and subjective measures of sleep, in young adults. 

The results from this study will help to elucidate the impact of caffeine consumption on sleep quality in young adults and determine the prevalence of poor sleep quality in NZ young adults. 

Who are we looking for?
- aged between 18-25 years old 
- fluent in reading and writing English 
- in good general health, with no history of heart disease, neurologic or psychiatric illness 
- without any current sleeping problems 
- not employed as a shift-worker

Eating habits of Preschool Children in New Zealand

Inadequate nutrition during infancy and early childhood is associated with a range of health issues including poor growth and development, overweight, obesity and nutrition related disease.  Identifying those most at risk of poor nutrition is the first step to providing interventions and access to services such as Dietitians and other health professionals. This research is investigating nutrition habits of preschool children aged 2 to 5 years old in rural and suburban areas of New Zealand and aims to include a wide range of ethnicities and socio-economic backgrounds. The findings of the research may assist with further research and development of nutrition interventions for preschool aged children at highest nutrition risk in New Zealand.

Inclusion Criteria

·       Being a parent/primary caregiver of a preschool child (two to five years old) 

·       Having lived in New Zealand for the last 5 years

Feeding Babies Study

We would like to invite you to take part in the Feeding Babies study, which aims to develop and validate a tool to assess nutrient intake in infants aged between 9 and 12 months.

It is well known that a baby’s diet is important for their early growth and development. To assess a baby’s diet there are a range of dietary assessment methods available. Some of the traditional dietary assessment methods are time consuming and not appropriate to the infant population.

Therefore, the aim of this study is to validate a new quick and easy dietary assessment tool, (an online questionnaire) against the traditional gold standard method (a food diary) to assess its validity and accuracy to assess nutrient intake.

Recruitment for this study has now been completed. Thank you to all those that took, or are currently taking part. A summary of the results will be posted here once completed.

Preschoolers & Vitamin D Study - Te Ra Whakaora

We mostly get Vitamin D from the sun, which is very important for building strong bones and maintaining good health. Researchers know something about the vitamin D status of New Zealand adults, and a little about newborn babies, but we know very little about the vitamin D levels of our preschoolers.

We will be able to create a simple questionnaire-type tool from the data collected in this study which health professionals can use to decide if a child is at risk of vitamin D deficiency. This means they can be identified early, before their health is potentially affected.
