Summary

The participants will visit the laboratory on 3 occasions, once for a preliminary visit and a further two occasions to complete experimental trials in a randomised order. The experimental trials will consist of cycling under two conditions; HIIE-First followed by Continuous (Trial-A) or Continuous-First followed by HIIE (Trial-B). Participants will be asked to standardise their diet for 24-hours and complete an overnight fast prior to visiting the laboratory. Participants will then complete 60-min of cycling split throughout the day into two 30-min bouts, HIIE or continuous cycling before breakfast followed by a 3.5 hour rest period before completing their remaining 30-min HIIE or Continuous cycling before lunch. Each experimental trail will last approximately 8 hours and begin at 08:00am. Throughout the trial measurements of subjective feelings of appetite, gastric emptying rate, substrate utilisation and regular blood samples will be taken. Post-trial nutritional and well-being questionnaires will be collected at 24-h post.

Study hypothesis

1. The order in which continuous and HIIE is undertaken will result in differences in gastric emptying rate after ingesting a semi-sold lunch?

2. Depending on which mode of exercise is undertaken first will result in different gastrointestinal hormone responses, metabolic responses and appetite responses throughout the trial day?

3. Will the order in which different modes of exercise, undertaken within the same day effect nutritional intake and well-being 24-h after both exercise bout have been completed?

4. Is substrate oxidation effected by the order in which multiple exercise bout of different modes are undertaken within the same day.

Description

There is a growing amount of literature committed to understanding if becoming more active will have beneficial effects on metabolic health; secondly do the traditional physical exercise and dietary approaches to managing obesity result in prolonged weight loss. The purpose of this study is to determine whether high intensity intermittent exercise (HIIE) and continuous exercise carried out in differing sequences within a day will have a beneficial health impact.

Participants will complete two 8h experimental trials in a randomised cross-over design. Each participant will complete 60-min of exercise in both trial arms; HIIE-First or Continuous-First separated by a minimum of 7 days. One trial will consist of a 30-min HIIE cycling session (10 x 1min of peak power output followed by 2min rest). After completion of this bout of exercise, participants will ingest a standardised breakfast. Following a rest period of 3h before completing the remaining 30-min of exercise (50% peak maximal oxygen uptake), before consuming a standardised semi-sold lunch meal. The second trial will be identical other than participates will undertake the continuous exercise first followed by the HIIE. Regular appetite, breath and blood samples will be taken throughout the trials. In The 24 hours following the end of each trial, participants will be asked to record their dietary intake and record their feeling of well-being documented on a questionnaire. There will be no long-term follow up following completion of the study.

Therefore, the aim of this research project is to identify whether the order of HIIE and continuous exercise separated within the day results in changes to gastrointestinal health, appetite, and metabolic responses.

Medical and Biotech [MESH] Definitions

Decrease in existing BODY WEIGHT.

An eating disorder that is characterized by the lack or loss of APPETITE, known as ANOREXIA. Other features include excess fear of becoming OVERWEIGHT; BODY IMAGE disturbance; significant WEIGHT LOSS; refusal to maintain minimal normal weight; and AMENORRHEA. This disorder occurs most frequently in adolescent females. (APA, Thesaurus of Psychological Index Terms, 1994)

A condition of involuntary weight loss of greater then 10% of baseline body weight. It is characterized by atrophy of muscles and depletion of lean body mass. Wasting is a sign of MALNUTRITION as a result of inadequate dietary intake, malabsorption, or hypermetabolism.

Inflammation of the PERICARDIUM that is characterized by the fibrous scarring and adhesion of both serous layers, the VISCERAL PERICARDIUM and the PARIETAL PERICARDIUM leading to the loss of pericardial cavity. The thickened pericardium severely restricts cardiac filling. Clinical signs include FATIGUE, muscle wasting, and WEIGHT LOSS.

General ill health, malnutrition, and weight loss, usually associated with chronic disease.
