Conditions

Low level physical activity Not Applicable

Interventions

1. Low level intermittent isometric exercise (leg press at less than 25kg of force). The participant will press against a fixed platform for 8 repetitions of 30 second rest / 30 second relaxation. 2

Eligibility

Inclusion criteria

Inclusion criteria: 1. 20 ? 40 years old 2. Healthy as determined by medical history 3. Signed consent given

Exclusion criteria

Exclusion criteria: 1. Pregnancy 2. History of eating disorders 3. History of metabolic diseases (e.g. diabetes) 4. History of cardiovascular disease 5. History of neurological or psychiatric disorders

Design outcomes

Primary

Measure	Time frame
Energy expenditure will be measured by indirect calorimetry before, during, and after each intervention	—

Secondary

Measure	Time frame
1. Cardiovascular response (heart rate and blood pressure) and EMG activity will be measured by continuous physiological monitoring before, during and after each intervention 2. Body composition will be measured at the start the study 3. Dietary and lifestyle information will be collected by questionnaire 4. Body temperature and habitual physical activity will be measured by wireless physiological monitoring over a period of one week 5. The interaction between each intervention and food will be measured (the protocol will be conducted once in the fasted state, and and once following the ingestion of a small, standardised meal).	—
