Chronic stress can cause changes in the feedback loop between the adrenals, brain and pituitary, leading to elevated levels of cortisol and epinephrine, which can have many harmful effects. However, there are ways to adjust these hormone levels, even when stressed, to minimize their negative impact.
During exercise, energy is first produced locally by muscle through phosphocreatine and carbohydrate stores. Your body prioritizes regulating blood glucose levels because glucose is a primary fuel source for the brain and will break down liver glycogen to maintain glucose concentrations in the blood if necessary, resulting in an increase in blood glucose concentrations during exercise instead of a decrease.
Research suggests that cognitive decline could be related to an energy problem, and trials with creatine and lactate show promising results in improving brain function among different populations.
The blood-brain barrier is responsible for allowing certain substances into the brain while keeping others out. However, the breakdown of this barrier, caused by factors such as sugar consumption, can lead to neuroinflammation.
This podcast discusses modifiable variables in strength training including frequency of training, choice of movements, order of movements, volume, and sets and repetitions. The frequency of training, for example, relates to the so-called split and affects the amount of energy needed to perform the workouts.
The type of food you eat can affect your circadian rhythm, wakefulness, and energy levels. Carbohydrate-rich meals tend to make us feel more tired due to their impact on tryptophan and serotonin levels.
