Training Principles

Training Principles

The aim of physical training principles is to facilitate and improve performance in specific physical tasks by stimulating structural and physiological adaptations in the body. The best approach to stimulate adaptations is to perform tailored exercises (prescribed using FITT parameters), governed by a set of training principles that activate specific energy supply systems. The key principles of training (1) to consider when planning/designing an exercise … Continue reading Training Principles

Training Adaptations

Training Adaptations

Physiologic Training adaptations obtained by demanding physical tasks can also be obtained through tailored physical activity or exercise. When the human body engages in a physical task, a series of changes happen in the physiologic systems to complete the task at hand. When the physical task is of a demanding nature beyond usual for a sustained period of time, the body’s physiologic systems undergo adaptations … Continue reading Training Adaptations

Forces of Nature

Our Universe runs with fundamental forces of nature. They are Electromagnetism, Strong force, Weak force and Gravitation. These forces are natural interactions that exist around us in our universe. Study about these interactions could explain our very existence in the universe. A living thing/organism is defined as an organism that shows signs of life, displaying abilities to breathe, ingest, metabolize, grow, move, reproduce and age. A … Continue reading Forces of Nature

Energy Transfer

Energy transfer follows the tenets of the first law of thermodynamics, which states that energy cannot be created or destroyed but transforms from one form to another. There is a flow of energy within a living body continually from one form to another. A kilocalorie (kCal) is a measure of a food’s potential energy trapped/stored within its chemical structure, which the muscular system changes into … Continue reading Energy Transfer

Energy Supply Systems

There are three energy supply systems in our body. All three systems work on a smooth continuum. ATP – PCr (Immediate) energy system: An immediate energy supply required for a physical activity such as 100 m sprint or lifting a heavy weight (high intensity – short duration), comes mainly from intramuscular high-energy phosphates, ATPs and PCr. Such (very fast) energy supply lasts only less than 10 seconds … Continue reading Energy Supply Systems
