Impact of Acute Resistance Exercise on Taste Perception and Appetite Response to Plant Protein in Resistance Trained Adults

Ireland29 participantsStarted 2022-08-08

Plain-language summary

Some evidence suggests that taste perception might be modulated by physical exercise, with differences observed after aerobic exercise (DOI:10.1093/chemse/23.4.417) and with habitual exercise (DOI:10.3390/nu11010155). However, the effects of resistance exercise on taste perception has not been studied. This knowledge is important as it may impact the acceptability of foods consumed after exercise. While plant-protein supplement powders are gaining increased popularity, their palatability and, thereby, acceptability may be a shortcoming. This randomised crossover trial aims to investigate (1) the taste perception and acceptability of plant protein supplement powders and (2) whether resistance exercise modulates taste perception and appetite responses to plant protein.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Part 1: Change in Taste Intensity

Timeframe: 2 hours: (1) baseline sampling session, (2) post-intervention sampling session (i.e. after 1 hour resistance training or rest).

Part 1: Change in Liking of the samples

Timeframe: 2 hours: (1) baseline sampling session, (2) post-intervention sampling session (i.e. after 1 hour resistance training or rest). Change scores will be compared between exercise and rest condition.

Part 2: Change in Appetite - Composite Appetite Score

Timeframe: 3.5 hours: (1) at participant arrival, (2) after exercise or resting condition (3) immediately after the protein bolus (4) 30 minutes after the protein bolus (5) 60 minutes after the protein bolus (6) after the lunch meal

Part 2: Energy Intake

Timeframe: Day 2 and Day 3
