Our study: Is fructose an essential ingredient in sports drinks?
Carbohydrates are the main fuel source during moderate- to high-intensity exercise (infographic, van Loon, 2001). Ingesting carbohydrates such as glucose during prolonged exercise has been shown to increase performance.

Our new study: are muscle capillaries important for muscle mass during aging?
A progressive loss of muscle mass and strength is observed during aging, which is termed sarcopenia. In addition, aging is also accompanied by a loss in capillaries (small blood vessels) that supplies tissues such as muscle with oxygen, nutrients, and growth factors. Is there a connection between muscle mass and capillarization?

Do short rest periods between sets blunt muscle growth?
Short rest periods (i.e. ≤ 1 min) between sets are popular in the gym. It is sometimes suggested that short rest periods may be beneficial because they stimulate a larger increase in circulating anabolic hormones (e.g. testosterone) compared to longer rest periods.

Does carnitine supplementation increase endurance performance?
Fat is an important fuel source during endurance exercise. To burn fat for energy (fat oxidation), fatty acids have to be transported into mitochondria (the powerhouses of cells). Carnitine helps fatty acids get into mitochondria. Therefore, carnitine supplementation might increase fat oxidation during exercise.

Can alcohol consumption affect muscle growth?
Exercise and protein ingestion are the main factors that stimulate muscle protein synthesis (the main process driving muscle adaptations such as growth).

Does the ketogenic diet increase fat loss?
The ketogenic diet restricts carbohydrates with the purpose of lowering insulin levels. Insulin is a hormone that is involved in fat metabolism. Therefore, some suggest that a ketogenic diet is very effective for fat loss.
