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.

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
