CHAPTER 2
LITERATURE REVIEW
Definition of Calorie
According to Ayoob( 2009), a calorie can be defined as a unit of heat energy that human body use as energy to produce heat. This energy fuels human body for strength in daily activity. In scientific term, there are two types of calories which small calorie and large calorie (Nordqvist, 2013).
A small calorie(symbol:cal) - 1cal is the amount of energy to required to raise one gram of water by one degree Celcius.
A large calorie(symbol:Cal,kcal) – 1Cal is the amount of energy required to raise one kilogram of water by one degree Celcius.
1 large calorie(1kcal) = 1000 small calories.
Calories can be found in fat, carbohydrate and protein. The main source of calorie comes from daily food intake. Too much calorie intake can lead to weight gain and too less calorie intake lead to weight loss. Therefore, in order to maintain body weight, consume calorie as only as much as body needed. (Jensen, 2001) . The body breaks down food molecules to release the energy stored within them. This energy is needed for vital functions like movement, thought, and growth -- anything that requires the use of energy. The body stores energy it does not need in the form of fat cells for future use.
Calorie Burning Factors
There are several factors that affect the calorie burning during walking phase which are grade of the walking surface, your weight, height, age, distance walking, step length, and speed. (Travis, 2013)
Elevation of surface – More calories are burned as the incline surface of the walking surface increase and less calories are burned as the decline of walking surface increase.
Weight – A bigger body weight exerts more effort and expends more energy running the...

The fundamental error in the calorie myth is that any calories you consume is exactly the same as any other calorie. The complicated reality is that energy in the diet come from different sources which route through different processes. To understand it, put on your lab coat for a couple of minutes.
Calories are a measurement for energy and are often measured as the heat energy absorbed from the digestion of foods (“Calories.”). Calories seen in labels of food are not measured in heat energy, but as estimated comparison of energy density (Atkins). Despite that calories are used as measurements of the energy in food, it is not the only thing t...
Past studies have showed mixed evidence regarding the effects of load carriage on stride length. Some studies have observed a decrease while others noticed no change in average stride length. Past studies have also been inconsistent with the usage of hip straps that are meant to transfer weight onto the larger muscles groups of the legs, which might lower metabolic cost. Our experiment considers both flat and inclined surfaces when determining whether backpack loads and the usage of hip and chest straps affect a walker's step length and post-exercise heartrate. The degree of increase of the post-exercise heartrate from the resting heartrate was used as a measure for fatigue in the subjects. Sixteen college students underwent eight walking trials on a treadmill on which the speed and distance traveled was fixed. Our data indicates that load carriage decreases average step length when the walker is on an inclined surface, but not on a flat surface. In addition, we found that load carrying, regardless of whether hip and chest straps are used, results in a greater increase in heartrate, both on a flat and inclined surface. Hip and chest straps used with loads are found to result in a lower increase in heartrate on flat surfaces, indicating a possible metabolic benefit of its usage.
When you exercise or actually when you just move, you spend your energies. Energy is needed for the body to move and stay alive and grow to keep the body warm.

The strict limitation of carbohydrates in a diet may appear to give the desired result of weight loss, but actually brings many health risks. Instead, carbohydrates help to reduce health risks, and also provide your body with key sources of energy. Not only are carbohydrates the main source of energy for the body, but they also create fiber which helps the body’s organs to function properly. The consumption of carbohydrates is important for normal functions of the body, but especially for the performance of an athlete. In order for maximum athletic performance, a large amount of carbohydrates must be consumed throughout the period of a workout. Overall the right amount of carbohydrates and exercise are necessary for a healthy diet.

Carbohydrates. This is the main source of energy for the body. Our bodies use carbs in the form of glucose for our brain to gain energy to function correctly. The carbohydrates that the brain does not use, is stored as reserve energy. Carbohydrates are very important as not only do they give energy to the brain, but carbs are also a source of calories to help maintain body weight.
In chapter 6 of Without The Hot Air, what is being discussed is how much energy is consumed in terms of food or drinks. For example: a tennis player has taken 1.00 kg of water that has been evaporated through perspiration and done 1.00 x 10^6 J of work in a game. Applying knowledge learnt from PHYS 151, I can determine the internal energy change of the player and the minimum nutrition calories needed to restore his energy level. The first law of thermodynamics states that total energy of an isolated system is constant; energy can be transformed from one form to another, but it can neither be created or destroyed. For the example, this means that the change of internal energy of the player is equal to the heat transferred to the system less

Balancing the calories you use through physical activity with the calories you eat will help you achieve your desired weight. When you eat more calories than you need to perform your day's activities, your body stores the extra calories and you gain weight (a). When you eat fewer calories than you use, your body uses the stored calories and you lose weight (b). When you eat the same amount of calories as your body uses, your weight stays the same (c).
