What factors affect our energy systems? – Discovery Learning

The Energy Systems Overview

Our bodies require energy for every cell in our body to do their job. But the amount of energy that we require varies drastically. If we compare all the complex metabolic functions in our body, exercise demands the most amount of energy. But then again intensity, duration and fitness levels of the exercise have a significant effect on how much energy is needed and how quickly it is needed. Our body has 3 different energy producing systems.

The three main energy systems are used for different types of physical activity.  These three systems are called:

The Creatine Phosphate System
The Anaerobic or Lactic Acid System
The Aerobic System

The first two systems are anaerobic systems, meaning they do not require oxygen to produce ATP (Adenosine Tri-phosphate). The third system is the aerobic system, which does require oxygen.

Where does energy come from and how to we store it?

We are designed to get our energy from the natural environment via the food that we eat. Everything that you eat or drink has to be digested to extract the energy from it. Our body can extract energy from three main food components known as macronutrients. They are:

Carbohydrates
Fats
Proteins

The process that our body uses to extract this energy from food (macronutrients) is digestion. The body has to break down the food we eat into chemicals that our bodies utilise to live. The calorific values of the 3 main macronutrients vary, with fat being the most calorie-dense at 9 kcals (calories) per gram, while protein and carbohydrate have 4 kcals per gram.

What factors affect our energy systems?

During aerobic exercise the use of carbohydrate relative to fat varies according to a number of factors.  The most important are:

The intensity of exercise
The duration of exercise
Your fitness level

Why And How Do We Put On Weight? – Discovery UK

Our body likes to keep things in balance and there is little doubt that regulation of bodyweight occurs, albeit with varying degrees of precision! Being overweight or obese is often considered to result from the failure of homeostatic mechanisms that regulate body weight during exposure to an environment that favours overeating and or discourages physical activity.

It is also important to emphasise that a fluctuating body weight is the general rule, even in adults who apparently maintain a stable body weight over months, years and decades, there is in reality no absolute constancy of bodyweight.  Instead, body weight tends to fluctuate or oscillate around a mean constant value, with small to large deviations from a ‘set’ or ‘preferred’ value. This is triggered by events that are seasonal and or cultural (weekends, holidays etc), psychological (stress, depression, anxiety or emotions) and pathological (ranging from minor health perturbations to more serious disease states).

Set point theory

The set point theory;  fat cells have a form of homeostatic control over body weight, is perhaps the most plausible explanation for long-term body stores. Set point theory states that each of us has a genetically pre-programmed set weight point that our bodies would prefer to maintain under normal circumstances. A hormone called leptin which is our natural appetite suppressant  is produced in the adipocyte and is responsible for appetite and bodyweight control.  As fat cells become full they increase production of leptin which leads to a reduction in appetite.  However most people don’t respond to appetite that well but instead are susceptible to marketing, ubiquitous snacks and the social and environmental pressures that make us all eat more than we should.  Chronic overeating will lead to a situation of leptin resistance at which point, hunger is always present.  This is part of the vicious cycle of weight gain that is not fully understood.

The existence of this set point explains why most diets don’t work – they are too short term in their approach to changing weight and simply lead to a temporary shrinking of the fat cell which leads to adiposity rebound. While the obese individual can fight off the impulse to eat for a time (lower levels of leptin), eventually the signal becomes too strong to ignore. The result is rebound overeating with individuals often exceeding their previous weight.
