Why Choose Pulse 8 – Jargon Buster
Strength can be defined as muscular strength, muscular power or muscular endurance. The maximal force that a muscle or muscle group can generate is termed strength. This can be determined by a person’s 1RM (1 Repetition Maximum); the amount of weight a person can lift in 1 repetition only! Muscular power is the explosive aspect of strength, and is the product of strength and speed of movement. It can be determined through the following equation:
During exercise, oxygen demand in the active muscles increases rapidly. More nutrients are used. Metabolic processes speed up, so more waste is created. During prolonged exercise, body temperature will increase. In intense exercise your levels of H+ ions will increase, which in turn lower the body’s pH balance and you experience increases in acid in the muscles; this is known as lactic acid. All these things happen during cardiovascular exercise, so it is important to make sure our body is ready to try and combat these things.
Sport Specific training is a vital ingredient to anyone wishing to become better at his or her chosen sport. Not only will it give you the edge over others in regards to strength and skill development, but you will also gain important cardiorespiratory adaptations.
Overweight and obesity are terms often used interchangeably when in fact they both have different meanings. Overweight is when body weight that exceeds the normal or standard weight for an individual based on height and frame size. Obesity refers to the condition of having an excessive amount of body fat. This implies that the actual amount of body fat or its percentage of total weight must assess or estimated.
Obesity has also been directly related to:
However the human body does need a certain amount of fat in order to function properly. Without certain amounts fat your body will start to break down muscle fibres in order to keep the body warm, give you the energy you need and to keep the central nervous system functioning normally. Males 5% or under would be considered under fat and 10% or under for Females.
Exact standards for allowable fat percentages have not been established. However men with more than 25% body fat and women with more than 35% should be considered obese. Men with relative fat values of 20% to 25% and women with values of 30% to 35% should be considered borderline obese.
Over 33% of the adult population is overweight, and the prevalence of obesity in children is increasing at an alarming rate.
The average person gains 0.45kg (1lb) per year after the age of 25, but also loses 0.2kg (0.5lb) of fat free mass per year, meaning a net gain of 0.7kg (1.5 lb) of fat each year.
There are a number of common ways in which we can measure weight and body fat:
BMI (Body Mass Index) is frequently used to estimate obesity by dividing body weight in kilograms by the square of body height in meters.
Skinfold thickness measurement of the tricep and subscapular is another measurement used to estimate the degree of leanness or obesity.
Tanita scales are the most modern and accurate way of measuring body fat percentage. The scales work by passing an electrical current through the body using your body water. Muscle fibres cause more resistance in the current than fat stores and from that you are given an overall body fat percentage as well as other readings including hydration levels, fat mass (kg) and fat free mass (kg). Speak to an instructor and get yourself measured and you can use this facility as many times as you like to help to track progression and achieve your goals.
A typical weight loss program in a gym would include lots of cardiovascular exercise (burning lots of calories). In order to lose weight your calorie output needs to be greater than your calorie input. A healthy start would be to burn between 300 and 500 calories per gym session 3 times a week.
For best results the highest calorie count will be achieved using the treadmill at medium speed or faster (i.e. not walking) or the x-trainer.
