Physiology Friday #251: Does Our Body Have a ‘Muscle Memory’ for Aerobic Exercise?

Physiologically Speaking

Muscle memory is a concept in exercise science that highlights the remarkable ability of muscles to "remember" prior training, allowing for quicker adaptations when retraining after a break. The concept of muscle memory is quite simple: It suggests that our body will have an enhanced response to a specific exercise stimulus (i.e.,

Physiology Friday #253: Low-carb Matches High-carb for Performance: Is it Time to Question the Obligatory Role of Glycogen for Endurance Exercise?

Physiologically Speaking

Adding to this controversy are questions about carbohydrate supplementation during exercise, particularly whether minimal carbohydrate intake can deliver performance benefits or if higher intakes are necessary to sustain energy levels and delay fatigue. And how effective is minimal carbohydrate supplementation during prolonged exercise?

Physiology Friday #262: Everything You Need to Know about Zone 2 Training

Physiologically Speaking

In a 5-zone training model, zone 2 is the highest exercise intensity you can sustain while remaining predominantly aerobic (oxygen-driven). Physiologically, this results in faster recovery between and during workouts, improved endurance performance, and increased fatigue resistance during longer exercise sessions or competitions.
