Fundamental Movement Skills are in the decline. "The obesity rate for children and adolescents is also high, with 22.2% of adolescents ages 12–19, 20.7% of children ages 6–11, and 12.7% of children ages 2–5 being obese as of March 2020." CDC.

Motor learning in sport. Let's dig in ====>

The concept of a motor program is related to information processing in the time period during which a motor task is being performed. There is a great difference between a conscious execution of a motor task (verbal–cognitive phase) and an automated execu- tion. - Schmidt, 1991

Your CNS is always moving through functions to guide movement.

Motor learning of a given sports technique requires a plan, which Schmidt (1977) defined as a "scheme" being stored in the motor memory. I am speaking to you, the average person. It's the same with basic things like walking, climbing stairs, and picking items up from the floor.

The movement scheme has four elements: − the position of body parts, position of the tool, the grip and balance of the body; − Information about the speed, − Information about movement transmitted by kinesthetic receptors; − Information about the outcome

The brain has two distinct halves, left and right hemispheres, that communicate through a neural bridge (corpus callosum, CC). With more than 200 million nerve fibers, the CC transfers information between both sides for synchrony in sensory, motor, and cognitive signals.

The older we get, the more the brain specializes, forcing hemispheres dominance. This is why "play" can be so important for youth and adults alike.

How are you guiding your movement? How are you shaping your environment for your goals? Ex: gym, running, crosswords, coloring. Motor learning is connected to all cause mortality....

"Play" offers a variety of movements that interplay with both hemispheres, ensuring "plans" on both sides. This can support long-term motor control health and lower risks of all cause mortality.

As we age, there are distinct differences in tissue adaptations. Reminder, you aren't just training muscle... #exercisephysiology

In general, satellite cell numbers as well as cell function decrease with age. Your "training age" really affects the satellite cell rate of change as you age. #exercisephysiology

The ECM (extra cellular matrix) continues to be underrepresented in fitness conversation. #exercisephysiology

The ECM surrounds cells and tissues as secondary support. In cell growth, the ECM helps cell to cell communication due to a reservoir of growth factors and bioactive molecules. It is constantly remodeling itself based on our homeostasis. #exercisephysiology

Mitochondria are more than the powerhouses of the cell. They support cellular signaling between cells, regulate cell death, influence stem cell development, and seem to be the biggest factor in supporting longevity. #exercisephysiology

Mitochondria seem to be so important that researchers at the University of Virginia School of Medicine have discovered that improper calcium signaling in the mitochondria of immune cells can drive chronic inflammation known as "inflammaging". #exercise news.virginia.edu/content/inflam….

The control of glycolysis is a fine-tuned balance that involves allosteric enzymes. Diet and exercise are something you can control to "tune" for glycolytic flexibility. #exercisephysiology
