Trehalose solution, when ingested during prolonged exercise, offers performance benefits similar to glucose but with a more gradual blood sugar release. This study found that even 4% trehalose concentrations maintained exercise performance, suggesting its potential in sports nutrition.
Area of Science:
- Exercise Physiology
- Nutritional Science
- Biochemistry
Background:
- Trehalose ingestion during exercise leads to gradual blood glucose increases and insulin response compared to glucose.
- Trehalose aids in maintaining performance during the later stages of prolonged exercise.
Purpose of the Study:
- To determine the lowest effective concentration of trehalose for exploiting its performance-enhancing properties during exercise.
Main Methods:
- Healthy male participants (n=22) underwent randomized, cross-over trials involving 60-minute cycling exercise and Wingate tests.
- Participants ingested 500 mL of water, 8% glucose, or varying concentrations of trehalose (4%, 6%, 8%) during exercise.
- Blood glucose levels were measured at 12 points, and exercise performance was assessed by mean power in the Wingate test.
Main Results:
- No significant differences in exercise performance were observed across trehalose concentrations (8%, 6%, 4%) during high-intensity intermittent exercise.
- Trehalose ingestion demonstrated sustained performance in the later stages of prolonged exercise.
Conclusions:
- Trehalose is effective in maintaining exercise performance at concentrations as low as 4%.
- Trehalose shows potential for developing novel mixed carbohydrate solutions for athletes.
- Further research is needed to understand individual athlete responses to trehalose during endurance activities.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
