• Research 

     

    Patients and members of the public can get involved in our research in many different ways. Involving patients and the public in our research helps us to answer many research questions. The needs of all of our volunteers are always considered throughout the research process.

    Volunteer

    We often need volunteers for a wide range of our research studies. Each study follows a carefully designed protocol that has been approved by local ethics committees. Some of the studies may also provide a small inconvenience allowance.

    You would have to undergo safety screening before participating in any of our research studies. Please note that you cannot start to participate in a new medical research study within 3 months of finishing a different one. 

    If you would like to volunteer to participate in one of our studies, please see a list of the research projects we are currently recruiting for below.

    CHAIN I
    Find out more

    The CHAIN I Study (in partnership with CHAIN II) is investigating how inactivity affects the way that the body works. 

    The biological processes that underpin the relationship between physical activity levels and health remain unclear. Addressing this topic has been deemed vital within the field of human chronic diseases and aging, in order to help more adults reach old age in better health and maintain a good quality of life for longer.

    Therefore, we are looking for adults aged between 55 to 65 years who are not actively involved in exercise training or do not have a regular physical activity regimen, but walk between 8,000 and 10,000 steps per day.

    For six months, participants will be asked to reduce their daily physical activity to match the amount that most UK adults undertake. This is walking less than 4500 steps per day and increasing sitting time to 7hrs per day.

    Over this six month period, we will assess how body function, diet and activity levels.

    At the end of the 6-month period we will provide supervised reconditioning exercise sessions to restore fitness levels.

    CHAIN II
    Find out more

    The CHAIN II Study (in partnership with CHAIN I) is investigating how inactivity affects the way that the body works.

    The biological processes that underpin the relationship between physical activity levels and health remain unclear. CHAIN II aims to identify changes that occur in the functioning of tissues and organs in the body and the time frame that these changes occur, in response to increasing and decreasing physical activity levels. 

    Therefore, the CHAIN II Study is looking for adults aged between 55 to 65 years who are not actively invovled in exercise training, do not have a regular physical activity regimen, walk less than 5,000 steps per day and sit for more than 8 hours per day.

    For six months, participants will be asked to increase their daily physical activity by attending 3 supervised exercise sessions a week at the David Greenfield Human Physiology Unit within the University of Nottingham Medical School.

    Over this six month period, we will assess how body function, diet and activity levels.

    Menopause & Muscle Repair Study
    Learn more

    The Menopause & Muscle Repair study aims to explore the influence of the menopause on the skeletal muscle's ability to repair itself following exercise induced muscle damage. Previous research suggests that oestrogen plays a critical role in muscle repair, but this connection has yet to be investigated specifically in relation to the menopause—a phase where oestrogen levels significantly decline. To study this, we will assess muscle repair in both pre- and post-menopausal women, who will engage in exercise targeting the quadriceps (front thigh muscles). Blood samples and muscle biopsies will be collected before and after exercise over a four-day period to observe muscle recovery patterns.

    We are looking for pre- and post-menopausal women who meet the following criteria:

    • Aged 40-60 years
    • Non-smoking
    • BMI 19-29.9 kg/m²
    • Not currently on hormonal contraceptives or HRT
    • Not engaging in regular strength or aerobic exercise training

    Menopause & Muscle Mass Study
    Learn more

    Sarcopenia describes the progressive decline of muscle mass and strength with advancing age and is associated with increased frailty and morbidity, and evidence suggests it develops earlier in women compared to men. The earlier development of sarcopenia in women appears to coincide with the menopause. Exercise is known to increase muscle mass, but this response reduces with aging. In this study we will examine the effect of menopausal status and exercise on muscle mass, strength, and fat mass.

    We are looking for adult women who meet the following criteria:

    • BMI 18 - 30 kg/m²
    • Not taking HRT or hormonal contraceptives
    • Not engaging in regular resistance training

    MRI scanner
    Sodium-MRI Study
    Find out more

    Eccentric exercise is used to prevent musculoskeletal injuries and assist with rehabilitation. However, unaccustomed eccentric exercise can result in the development of muscle soreness and a loss of muscle strength and power in the days following exercise. The cause of these negative effects remains poorly understood, but recent advances in sodium-MRI now allows us to assess the biochemical mechanisms that may underpin such phenomena. Therefore, this study aims to use sodium-MRI scanning to investigate differences that occur in the amount of sodium which is inside and outside of muscle cells (and their relationship to the loss and recovery of muscle power) the days following an eccentric exercise training session.

    Requirements

    • Male
    • Healthy (i.e. no musculoskeletal conditions or chronic diseases)
    • Aged 18-35 years
    • BMI 18-27 kg/m2
    • Non-smoker, including electronic cigarettes
    • No regular exercise (i.e. <2 times per week)

    If interested, please contact Charles Steward for more information using the email link below.

    Pectin Study
    Find out more

    We are looking to recruit adults aged over 65 years to help us examine whether consuming the soluble dietary fibre, called pectin, affects appetite and food intake.

    Participants will be asked to:

    • Attend the Medical School (Queen's Medical Centre) for medical screening and 4 study visits (each ~4hrs).
    • Eat a standard breakfast and lunch on study days.
    • Keep a dietary and bowel habit record.
    • Answer questions about your appetite.
    • Consume 15g of pectin fibre (or placebo) a day, each for a week.

    Unfortunately, participants will not be eligible to take part in the study if:

    • they have a gastrointestinal condition.
    • have a specialised or restrictive diet and/or have food intolerences.
    • are taking medication that could affect appetite.
    • have diabetes mellitus and/or cardiovascular disease.
    • have taken part in a research study in the last 3 months.

    For participating in the study, participants will receive an Amazon voucher as a thank you.

    CRNitrateMRI Study
    Learn more

    The CRNitrateMRI study aims to investigate the combined effects of beetroot juice (dietary nitrate) plus a weight-loss diet (caloric restriction) on the brain and vascular functions in older adults (aged 60 - 75 years old). There is evidence to suggest that consuming beetroot juice, a good source of dietary nitrate, whilst restricting your energy intake may improves cognition (e.g., memory), brain blood flow, and blood vessel function with the results helping us to develop future studies to  test the effects of combining dietary nitrate and energy restriction in people at a higher risk of developing diseases related to cognitive declines, like dementia.

    The study will involve drinking beetroot juice and following a diet for 28 days. Participants will be required to have two brain MRI scans, along with measurements of cognitive and vascular function. 

    An inconvenience allowance will be paid and all food will be provided for the four week period.
