Coaching Sheet

Dear all, Please remember to send me the Group members in the team (Chairman!)

 Remember that the first name is the Captain of the team and the coach for the first session in Week 7.

The rest of the names in line are the coaches for the next sessions. I have also attached the coaching sheet for your completion. You may do it in soft or hard copy.

Body Composition: Skin-fold measurements - Desiree

Skin fold measurements is a way to estimate your body's fat composition. I prefer this method compared to the rest as it is easily available, simple, inexpensive, relatively accurate and not painful.

The Skinfold caliper is needed to carry out the measurements.

The Skin fold caliper is a device which measures the thickness of a fold of your skin with its underlying layer of fat. By doing this at the key locations can be a quite accurate representative of the total amount of fat that is on your body, it is also possible to estimate the total percent of bodyfat on your body.

Areas to test out: Triceps, biceps, shoulder blades and waist:

Body Com Bioelectrical impedance analysis Shaun Ng

Bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition, the method has become popular owing to its ease of use, portability of the equipment and its relatively low cost compared to some of the other methods of body composition analysis. It is familiar in the consumer market as a simple instrument for estimating body fat. It actually determines the electrical impedance, or opposition to the flow of an electric current through body tissues which can then be used to calculate an estimate of total body water (TBW). TBW can be used to estimate fat-free body mass and, by difference with body weight, body fat.

However, it is deemed not that accurate and the results varied a lot. 


Body Composition DEXA - Kai En


DEXA has many functions such as detecting the presence of osteoporosis in men and women with particular risk factors and monitoring bone density in those with low normal levels and in those with osteoporosis undergoing treatment. This method has multiple functions with low or no risks at all. And, all the patient has to do during this is to just lie down while the scanner passes over the patient's body. During this procedure, the patient will not feel any discomfort so it will be quite ideal. For this treatment, only simple preparations has to be made such as not consuming calcium supplements or avoid clothes with metal on them. This method is also one of the most accurate ones. Hence, this method is the most suited one.

DEXA- Ryan

Dual Energy X-Ray Absorptionmetry (DEXA)

2 X-ray beams of different energy levels are targeted at the subject's bones. Some of the beam is absorbed by the bone and the rest passes through it. In essence, it is an X-ray and will also show the broken bones of the subject. It is the most accurate way of measuring the total amount of fat in a person.

Pros: Extremely Accurate, most accurate among the other methods

Cons: Very costly to operate and use with each use going up to a few thousand. (due to the nature of how it works)

Preferred Mode of Measurement of Body Composition – Justin

I like the Bioelectrical Impedance that makes use of electrical impedance/conductivity in the body to measure the amounts of body fats and lean mass for the following reasons:

1. Readily available since the 1980s
It is very available, which saves time and costs when wanting to know our body composition.

2. Makes use of body compositions
Rather than using air pressure or measurements, the BI makes use of the Total Body Water standard in our bodies to accurately measure how much fat content we should have.
The disadvantage of this is the consumption of water, which may cause this value to alter. 

Body Composition: Wee Chang Han, Skinfold measurement

The Skinfold measurement is the most efficient method to measure one's body composition in my opinion as it is quick and easy to do.

Some of the advantages of the Skinfold measurements is that it is widely utilized to assess body composition. It is a lot simpler than hydrostatic weighing and many of the other body composition techniques. After the original outlay for calipers, the daily tests costs are minimal.

Thus, the skin fold method can be used by many clinics and hospitals as it does not cost a fortune and does not require a huge amount of time to be spent on training. It can also measure up to many different parts of the body, unlike other methods which can only measure the entire body at once. This can accurately pinpoint the area that needs fats to be removed.

Disadvantages:
Due to its reliance of human, human error may be inevitable and present in the recording, which results in a need of an average or another device to confirm the results.
