Physiological Adaptations

Physiological Adaptations2018-10-04T22:40:43+10:00

Physiological adaptations are always specific to the training and stress placed upon the body. It is the adaptations that occur that cause the improvement in performance after training.

Training that uses the principles of training will cause more adaptations than training that does not. Adaptations require training above the thresholds and create the need for an increased workload according to the principle of progressive overload.

Physiological adaptations are lost when training stops and are more complete when training involves various activities. Adaptations in response to training include: decreased resting heart rate, increased stroke volume and cardiac output, increased oxygen uptake, increased haemoglobin levels in the blood, muscular hypertrophy, and various other changes within the muscles themselves (increased myoglobin, increased mitochondria, increased aerobic or anaerobic enzymes according to training specificity, increased lactate thresholds, and much more).
