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

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.

Exercise

The total volume of exercise is 40 repetitions of each of the 4 exercises. The participant is instructed to perform a maximum of 10 repetitions each set, with 1'30'' rest between sets and between exercises. The researcher provides instructions and verbal encouragement. The total duration of the exercise bout is between 1 hour and 1 hour and 15 minutes. Part 1: Before and after the exercise condition the participant is sampling 8 different samples: (1) sucrose (2) umami (3) soy protein (4) pea protein (5) hemp protein (6) brown rice (7) whey protein and (8) apple juice. All protein sources are 3 grams dissolved in 20ml apple juice. Sucrose is 1.66g in 20ml water and umami tastant is 0.09g in 20ml water. Part 2: a 30g soy protein bolus in 200ml apple juice is given to the participant. After 1 hour energy intake is assessed with an ad libitum lunch meal.

Rest

The participant remains in sedentary activities such as reading or using a laptop. Part 1: Before and after the rest condition the participant is sampling 8 different samples: (1) sucrose (2) umami (3) soy protein (4) pea protein (5) hemp protein (6) brown rice (7) whey protein and (8) apple juice. All protein sources are 3 grams dissolved in 20ml apple juice. Sucrose is 1.66g in 20ml water and umami tastant is 0.09g in 20ml water. Part 2: a 30g soy protein bolus in 200ml apple juice is given to the participant. After 1 hour energy intake is assessed with an ad libitum lunch meal.
