HIT Training in the Frail Elderly.
- Conditions
- SarcopeniaAgedExercisePreoperative Care
- Registration Number
- NCT03138265
- Lead Sponsor
- University of Nottingham
- Brief Summary
This pilot study aims to investigate whether high intensity interval training can result in rapid improvements in physical fitness amongst the frail elderly (over 70 years old). Participants will undergo a wide range of physical fitness measures followed by a four week exercise protocol. Determination of improvement will be by repeated testing of the physical measures taken for baseline. The primary outcome measure will be anaerobic threshold. There will also be a subgroup of participants who will undergo muscle biopsy and D2O ingestion to allow an insight into the mechanistic basis behind exercise training response in this age group.

- Severe respiratory disease inc. known pulmonary hypertension(>25 mmHg), Forced -Expiratory Volume in 1 second <1.5l.
- Brittle asthma / exercise induced asthma
- Known cerebral aneurysm or abdominal aortic aneurysm.
- Cognitive impairment, which may reduce individuals' ability to provide informed consent.
- Inclusion in a recent study which included any form of exercise, taking a drug or ionising radiation.
Exclusion criteria pertaining specifically to muscle biopsies:
- Current use of anticoagulation (i.e. Warfarin/Clopidogrel/Rivaroxaban)
- Any pre-existing clotting disorders known to the patient (i.e. haemophilia).
- Family history of severe bleeding requiring medical intervention.
- Any musculoskeletal deformity or skin conditions making the taking of a biopsy unsuitable as deemed by the medical practitioner taking that sample.
- Lack of capacity to fully consent for the procedure.

- Primary Outcome Measures
Name Time Method Mean anaerobic threshold improvement following 4 week HIT protocol. 4 weeks Measured via cardiopulmonary exercise testing (mls/kg/min and absolute value L/kg). Pre-Post testing.
- Secondary Outcome Measures
Name Time Method Mean VO2 peak improvement following 4 week HIT protocol. 4 weeks Measured via cardiopulmonary exercise testing (mls/kg/min and absolute value L/kg). Pre-Post testing.
Muscle protein synthesis 4 weeks Assessment of D2O evaluated muscle protein synthesis following HIT programme. Using mass spectrometry for analysis of stable isotope uptake during training program (arbitrary units).
Body composition 4 weeks DXA changes in body composition (lean muscle mass (%), fat mass (%) and bone density g/cm3)) following a HIT programme
Muscle architecture 4 weeks Ultrasound scans used to assess changes in lean muscle mass and architecture following a HIT programme (mm and % pennation angle change).
Feasibility 4 Weeks Determination of frail elderly patient adherence to HIT programme (number of scheduled sessions successfully completed within 28 days).
Quality of life improvement 4 weeks Quality of life questionnaires to measure subjective outcomes (EQ-5D questionnaire)
Daily Activity Level 4 weeks Activity questionnaire to quantify habitual physical activity (IPAQ questionnaire)
Physical Activity Score 4 weeks Subjective assessment of physical ability (DASI questionnaire)
