Age-related changes in the brain include a reduction in gray matter volume, which is thought to be directly influenced by our level of physical activity and body composition. Can these factors slow cerebral aging and improve cognitive health in the long term?
The popularity of BCAAs (branched-chain amino acids) rests mainly on the fact that they are said to stimulate muscle protein synthesis and reduce proteolysis, thus promulgating a positive net protein balance. But are they really necessary?
It has been suggested that humans have a finite potential in their ability to grow skeletal muscle. However, if this plateau does exist, are there other physiological factors, in addition to genetic predisposition, that put the brakes on our muscle gains?
In the world of fitness, it's not always easy to sort the truth from the falsehood. And creatine is a victim of its own success. From unjustified fears about its safety to misunderstandings about its effects, creatine is often demonized.
Creatine is mostly associated with enhanced athletic performance and muscle growth. However, recent scientific explorations have shed light on a different, but equally important, aspect of this well-known supplement: its impact on brain health.
Resistance training is particularly recommended for its health benefits. However, lack of time is the main reason given for not exercising. Is there a minimum dose that would still provide some benefits?
Considered a factor in longevity, muscle strength decreases with aging. The minimum recommended doses and relatively short longitudinal studies do not allow us to know the real evolution of strength over the course of a lifetime. The study of powerlifters provides more information.
The squat has always been considered the king of exercises for developing the muscles of the lower limbs, particularly the glutes. In recent years, however, the hip thrust seems to have taken its place. But is it justified?
