The Harpenden Portable Stadiometer is a counter recording instrument and has been designed to give all the advantages of the Harpenden wall-mounted Stadiometer in a portable form. The Harpenden Portable Stadiometer is fitted with a high speed Veeder-Root counter. Harpenden Stadiometer. 2017 United Kindom ex-works price: £1043.00 (excl VAT where applicable). The 'Harpenden' Stadiometer is a counter recording instrument, with an effortless counter balanced movement. It will give an accurate and direct reading of a subject's height, to the nearest millimetre over a. For instance, in Caucasian men in winter or spring who were >80 yr old, did not engage in lawn/garden work, and had a body mass index greater than 25 kg/m2 and. Height (centimeters) was measured on Harpenden stadiometers, and weight (kilograms) was measured on standard balance beam or digital scales.

Background Accurate measurement of physical activity is a pre-requisite for monitoring population health and for evaluating effective interventions. The International Physical Activity Questionnaire (IPAQ) is used as a comparable and standardised self-report measure of habitual physical activity of populations from different countries and socio-cultural contexts. The IPAQ has been modified to produce a New Zealand physical activity questionnaire (NZPAQ). The aim of this study was to validate the IPAQ and NZPAQ against doubly labelled water (DLW). Method: Total energy expenditure (TEE) was measured over a 15-day period using DLW. Activity-related energy expenditure (AEE) was estimated by subtracting the energy expenditure from resting metabolic rate and thermic effect of feeding from TEE. Eyebeam License Key Generator.

The IPAQ (long form) and NZPAQ (short form) were completed at the end of each 7-day period. Activity-related energy expenditure (IPAQ AEE and NZPAQ AEE) was calculated from each questionnaire and compared to DLW AEE. Background The global estimate for physical inactivity (doing very little or no physical activity at work, at home, for transport or in discretionary time) is 17% [], whereas the estimate for insufficient levels of physical activity (. Study participants and recruitment Adults living in Auckland, New Zealand were eligible if they were aged between 18 and 65 years, able to give written informed consent, able to communicate in English, and weight stable (not dieting or had not experienced recent dramatic changes in weight).

Potential participants were recruited via community advertisements, direct contact through the university, and word of mouth. Adults who used a walking aid (crutches, cane, or wheelchair) or who were unable to perform physical activity for medical reasons were excluded. The study protocol and related documents were approved by the Northern Regional Ethics Committee (NTY/06/02/011). Doubly labelled water (DLW) DLW is considered the reference or gold standard for the assessment of total energy expenditure (TEE).

When combined with a measure of resting metabolic rate (RMR), activity-related energy expenditure (AEE) can be calculated []. In this study TEE was determined using the DLW method [,]. After a baseline urine sample was collected for determination of background isotope enrichment (Day 0), each participant ingested a single dose of DLW ( 2H and 18O; Cambridge Isotope Laboratories, Inc., Andover, MA), corresponding to 0.12 g of 99.9% of 2H 2O and 2 g of 10% 18O per kg body weight. Download Lagu Simple Plan Jet Lag Remix. The dose was followed by the ingestion of two 50-mL washes of the container with tap water. Post enrichment urine samples were collected the following day (Day 1) and at Days 8 and 15. A trained research assistant collected all specimens and recorded the exact time of voiding.

Samples were frozen at -21°C until assayed for 2H and 18O. A subsample of the dose was reserved and after appropriate dilution analyzed at the same time as the urine samples to serve as a reference point.

Samples were analysed in triplicate using a TC/EA (Thermo Chemical Elemental Analyser) interfaced (ConFlo II; Thermo Finnigan, Bremen, Germany) to an isotope ratio mass spectrometer (Delta Plus XP; Thermo Finnigan, Germany). TEE was calculated using the two point approach with an assumed respiratory quotient (RQ) of 0.85 over the 14 d period []. Activity-related energy expenditure (AEE) was calculated as the difference between TEE and RMR. For the purpose of this study, diet-induced thermogenesis (DIT) was considered to be 10% of TEE []. Body composition Anthropometric measurements were taken in the morning of Day 1. Height was measured to the nearest 0.1 cm with a portable stadiometer (Harpenden Stadiometer, Chasmors Ltd, London) and weight was measured to the nearest 0.1 kg on an electronic scale (Salter Scales). To assess body composition, resistance, reactance, impedance and phase were determined using single-frequency (50 kHz) bioimpedance analysis (Model BIM4, Impedimed, Capalaba, Australia) using a standardized protocol.
