The absorption of carbohydrates via the intestinal epithelium is achieved by transport proteins. Glucose is transported by a sodium-dependent glucose transporter 1 (SGLT1). This protein becomes saturated with a high glucose intake of approximately 60g per hour. GLUT5 is another transporter that transports fructose. If both transporters are used simultaneously, it is possible to absorb…
Master athletes (40 years and over) can attain similar levels of fatigue resistance, muscle mass, strength and power to younger individuals. This helps to delay the onset of many adverse health events associated with ‘normal’ aging. Nonetheless, despite the impressively high level of performance in Master athletes, musculoskeletal deterioration remains somewhat inevitable with advancing age.…
Protein synthesis underpins adaptations of muscle mass, muscle strength, and all other adaptations to training. Protein quality can be an important factor to increase protein synthesis. The amount of Leucine contribute to the degree in which a protein source can increase protein synthesis. A higher quality protein will do this more effectively. Protein sources with…
Lately you will undoubtedly have seen it once in the media: (the hype) about collagen! You can get a tight skin and it is a miracle cure that we should all use? What is Collagen? Collagen is the most abundant protein in the body. It has countless functions and you can create it yourself. But…
This article explores the different energy systems behind the training zones. The different systems will be described from small to large. All systems are trainable, which means that they can all improve when training is done in the different training zones. ATP ATP stands for Adenosine TriPhosphate. A mouthful for the non-chemists among us, but…
