Trying to gain muscle mass or reduce Skinfold measurement for athletic performance fat mass? There are a variety Hyperglycemia and eye health measurements that tell you Herbal extract benefits lot more information about your body than simple weight measurement does, Skinfold measurement for athletic performance example DXA scans, Bod Pods, BIA and surface athlftic skinfolds.
Skinfold measurement for athletic performance types of measurements all come with their own unique set of errors and benefits with their estimation of physique. See the table athletjc for a summary of the accuracy and reliability Calcium and kidney health different body composition assessments Hyperglycemia and eye health can be undertaken:.
At Precision Athletica, Hyperglycemia and eye health primarily measuremrnt skinfold measurements. Boosting digestion naturally are a robust Protecting joint function naturally that is relatively measutement, convenient and Hyperglycemia and eye health, Blood sugar control for weight loss does not require measuremeent fasting beforehand, compared to other methods which are more expensive and can give variable results performsnce on the time of day, meals eaten and hydration Lower cholesterol for better blood flow. In athletuc skinfolds assessment, Hyperglycemia and eye health anatomically defined sites on the body triceps, subscapular, biceps, measurment crest, supraspinale, abdominal, front thigh and medial performancr are marked mesaurement then perormance subcutaneous fat fat below the surface of the perflrmance using skinfold callipers.
The sites are chosen to account for individual variations in body neasurement distribution and Skifnold results are given as a sum of the oerformance sites some sports will only measure 7 sites, leaving out the Skinfold measurement for athletic performance crest measurmeent.
Skinfolds only measure subcutaneous fat, not visceral fat, Skiinfold is the ,easurement fat ror organs, however mewsurement is not Skinfold measurement for athletic performance an issue for athletes.
In general, meaaurement increase in skinfolds performznce associated with an increase performqnce body fat, while decreased skinfolds is associated with a reduction in body fat stores. Skinfolds are typically assessed in conjunction with your body mass, to offer an insight into changes in both fat and muscle mass i.
increased weight with reduced skinfolds could reflect increased muscle mass. See the table below for an example of how your skinfolds can be interpreted to assess changes in body composition:. As with many types of measurements, there is a margin of error associated with skinfold assessments.
You will be given a sum of your 8 or 7 skinfold sites, but this should also be presented as a range to allow for measurement error. When you have a subsequent skinfold measurement, if your skinfolds sum is not in the range of the previous measurement, then you know there has been a true change in fat mass, however if it falls within that range then it can be viewed that skinfolds have remained stable.
Frequent ongoing measurement of your skinfolds will be a valuable tool in helping you monitor body composition over time. We recommend every weeks depending on the athlete and sport.
When using your body weight to compliment your skinfold assessments, remember to weigh yourself at the same time every time you weigh yourself as weight can be influenced by the time of day or month for females and hydration status lighter if dehydrated. Anyone can have their skinfolds done.
If you have a goal of increasing your muscle mass, assessing skinfolds will show you whether increases in mass are due to increases of muscle, fat mass or both. In sports, skinfolds are another tool used to assess the effectiveness of your training. Some sports have certain physique traits associated with them, such as gymnastics or diving.
In endurance sports such as marathons and cycling, lower body fat levels enhance efficiency and heat dissipation.
In other sports with weight classes such as rowing or boxing, lower body fat levels will help enhance power to weight ratio compared to smaller, less muscular opponents. In team sports such as rugby, different positions on the field have different roles requiring different body compositions to effectively be able to achieve their roles.
Ongoing skinfold assessments are the most effective tool for monitoring body composition changes over time, and as an athlete, are just one of your tools that you can use to assess your progress in performance.

Written by: Michelle Rockwell, MS, RD, CSSD, Virginia Polytechnic Institute and State University Body composition is a physical measurement that provides more specific information about body make-up than body weight alone. Does body composition impact athletic performance and health? Assessing body composition There are many different methods for evaluating body composition. Assessment tools and methods used with college student-athletes: In the collegiate setting, numerous assessment tools are used. Considerations about body composition analysis: A body composition measurement from one method cannot be compared to one from another. For example, a football player evaluated by DEXA at his university cannot compare results to the BodPod values he receives at the NFL combine. Likewise, when tester or equipment variation comes into play, results also cannot be compared. A cross country runner who has skinfold caliper measurements performed by her strength and conditioning coach cannot compare results to the same measurements taken by the sports dietitian. Measuring via the same method in a systematic way offers the most benefit for individuals and team analysis. Measurements should be done in private. Results should be handled with sensitivity. The National Athletic Trainers Association suggests that body composition results be treated the same as other medical information with regard to confidentiality. Measurements should be taken when student-athletes are well-hydrated and before exercise. In general, measurements should be taken no more frequently than every two to three months. Some professionals recommend twice per year or less. Defer to your sports dietitian regarding specific student-athlete protocols. There should always be a purpose for taking measurement. Clear and consistent communication is paramount. Testers must be sensitive to the impact of assessment on student-athletes. If resources are not available to assist with the management of body composition information and education, its best to avoid it altogether. Communicating about body composition Always emphasize performance measures, overall training, diet and healthy lifestyle as highest priority for athletes. When body composition change is appropriate, establish a percent body fat range rather than an absolute value. Changes in body composition should be gradual and targeted changes are priority in the off-season whenever possible. Guide student-athletes to focus on FFM as much as they focus on percent body fat as this is functional, powerful athletic tissue they wish to maintain or increase and can feel more positive than focusing on decreasing percent body fat. It is recommended that athletics departments develop guidelines and protocol for measurement, analysis and communication of body composition data. Table 3. May feel intrusive to some athletes. Body composition then estimated using equations.

| Skinfold Calipers | To start, body fat plays an important role in keeping our bodies functioning and well. Women, in particular, need more body fat. Body fat is also a key source of energy and important hormones. As mentioned earlier it is important to keep in mind that these calculations are estimates only. Therefore, your body fat percentage is probably not that accurate. It can be daunting reading into how much body fat you have or being classified into a certain body type. There is too much pressure being put on athletes and now the general population to be a certain skin fold or body fat percentage. Although this is drastically changing in professional sport, it, unfortunately, is lagging with age group athletes and in the general population. This is why I urge you not to worry about what the numbers say. When discussing body fat percentage, it is important that is not only 1, probably inaccurate, but also 2, it could trigger or lead to other psychological issues in individuals that may already be feeling insecure. Getting skinfolds or a scan done, can help to track changes made throughout training. These measurements can be good for creating a discussion , and possibly determine if any weight change is predominately muscle gain or if any weight lost is predominately fat loss. Many coaches and health professionals working with athletes may want to measure body comp for an indication of how their support is working for their athlete. Then, some of you just like having the numbers. That is great, but this is definitely not the only way to measure your progress. It is important to focus on how you and your body are feeling during your training first. Have you progressed with your training? Are you hitting your performance targets? Are you getting sick or injured often? Is your menstrual cycle regular? These questions are far more important than any number. However, if you are getting body composition measured, remember the following:. There is some error with whatever method of measuring you decide to use. Your results are a good guide, but they should not be taken as a be all and end-all. The time of day, what you have had to eat and drink can affect your results. It is best to measure at the same time on every occasion and consider eating similar foods prior to being measured. For those measuring body composition, it is important to know what the person's perception of their body is. If they have body image issues, we advise caution with the language you use. Changing your diet to alter your body composition may harm your health and performance. This will probably improve your performance beyond any number. Gibson, C.

For overweight or obese populations, taking skinfolds may be of less use, as accuracy and reliability of the skinfold measurements will be harder to repeat as the skinfold thickness increases, so methods like DEXA may be more accurate 5. Other studies, for example on obese children, have found good agreeance between skinfolds and percent fat measured by DEXA 22 , however, considerations based on the population being measured must be addressed by each case separately. In anthropometry, technical error of measure TEM is what we refer to the error that occurs when a measurement is taken on the same object more than once, and the values are not the same. This error is inherent especially when humans are involved in the measurements, due to:. We want to minimise the error in our measurement as much as possible to create the most accurate and reliable measurement possible each time, but all errors cannot usually be removed To minimise these factors, it is best that we control as many factors as possible, and use the same tester, the same location, the same time of day and day of the week, and a consistent schedule throughout the week in training and diet Because we know the error is associated with the measurements, practitioners should always express their measures as a value with the technical error, so that when measuring change over time, we can be more certain of real change versus errors made in measuring. To calculate the technical error, use the following equations, outlined in a paper by Perini et al. Table 1. Acceptable levels for intra- and inter-evaluator error, according to a beginner Level 1 ISAK versus a skilful anthropometrist Level 4 ISAK Finally, to make measurements of body composition more accurate, ensure the use of predictive body fat percentage equations that best match the demographic of the persons tested. Generally, the understanding of the use of skinfold calipers and their accuracy is very poor and grossly misunderstood. Given this, our mission was to clarify whether skinfolds are a good method of choice for body composition. In conclusion, skinfold calipers can be a cost-effective, quick, and relatively accurate measure of body composition over time. While the gold standard for body composition is still cadaver dissection, skinfold measurements can offer information about the relative fatness, the change in body composition over time, and potentially even the health of the individual. Knowing that increased fat mass is associated with various diseases, and some athletes need specific body fat percentages for optimal performance, it is of importance that fitness professionals measure skinfolds accurately and with the ability to be repeatable, following the ISAK for best results.

Skinfold measurement for athletic performance -
Each method has its pros and cons, and it is likely that there is no one technique that is optimal for all situations — this will be discussed in the following sections. Dual-Energy X-Ray Absorptiometry DEXA DEXA is based on a three-compartment model that measures bone mineral content, FM and FFM.
Two energies are used to allow estimates of soft tissue absorption, separate from bone 6. DEXA is considered the gold standard measurement tool for the diagnosis of osteopenia and osteoporosis 7.
It is fast, non-invasive, and only exposes individuals to a small amount of radiation. The DXA also has the added benefit of providing segmental body composition analysis, which may be of particular interest when looking at bone mineral density in some athletic populations.
Although it is often considered one of the most accurate methods of body composition analysis, it is not without limitations. In athletic populations, longitudinal data from repeated measurements of body composition may be affected by muscle glycogen levels, hydration status and changes in muscle metabolites such as creatine 8.
This may lead to a misrepresentation of FFM, and these factors should be considered when interpreting the results of DXA estimates of body composition. Skinfold Calipers Skinfold calipers measure a double fold of skin and subcutaneous adipose tissue and apply constant pressure to the site.
Skinfold measurements make the assumption that adipose tissue compresses in a predictable manner, that the thickness of the skin is negligible, and the double-layer compression is representative of an uncompressed single layer of adipose tissue. Measurements give results in millimetres, which can be then converted to a body fat percentage, with dozens of equations available for varying populations.
A potential limitation of skinfold measurements is that they are dependent on the competency and accuracy of the person taking the measurements i. intra-rater reliability. To minimise the technical error of measurement, measurement sites and techniques have previously been defined 9.
Practitioners can become accredited in anthropometric measurement through the International Society for the Advancement of Kinanthropometry ISAK. Skinfold measurements taken just one centimetre away from the defined ISAK sites have previously been shown to produce significant differences in measurement values at each site, indicating how important it is to mark and measure skinfolds correctly for accurate data Therefore, the intra-rater reliability of the test is extremely important.
Whole Body Plethysmography BodPod Air-displacement plethysmography ADP can allow for the calculation of body composition through a 2-compartment model, based on assumptions of value constants for FM and FFM densities. Body weight and body volume are determined by this method, with mass divided by volume providing a measure of density.
Again, this measurement is a non-invasive and quick method, with the advantage of not requiring exposure to radiation. BodPod has been shown to be a valid measure of group average body composition when compared to DEXA in female collegiate athletes However, research has suggested a difference of 5.
BodPod has also shown limited accuracy when attempting to determine changes over time 13 , a primary consideration when choosing an assessment method for athletes. Body density is determined and then used to estimate body fat percentage. Again, this estimate is based on assumptions regarding the density of FFM, which may vary with age, gender, ethnicity and training status, potentially limiting its use in athletic populations Although this method was previously considered the gold standard by the American College of Sports Medicine, it is not without measurement error.
The results are highly reliant on subject performance, and as the process itself is uncomfortable, it may take multiple tests to get a valid measurement. For example, measurement error can occur through unsuccessful attempts to blow all of the air out of the lungs, or air bubbles trapped in hair or swimsuits.
Bioelectrical Impedance Analysis BIA BIA is based on the concept that electric current flows through the body at different rates depending on its composition It involves running a light electrical current through the body and determining body composition through the resistance of the tissues to the electrical current.
The low cost, speed of measurement and lack of need for technical expertise make BIA an attractive option for body composition measurement, particularly in epidemiological research. However, the accuracy of BIA is dependent on several factors, and as a result, it is likely the least valid measure of body composition discussed in this article.
BIA relies on empirical equations to estimate total body water, FFM and body cell mass; these equations use gender, age, weight, height and race as variables. Therefore, for BIA to be used as a valid measure of body composition, the correct equation must be used based on these factors The validity of BIA in some populations has been questioned, particularly in obese patients 18 , and in those with conditions that may alter fluid distribution, such as oedema BIA data is influenced by hydration status, and although the standardisation of fluid intake in the hours before testing may reduce the effects of hydration on body composition measurements, there is a lack of standardisation, or at least its reporting, in current research This may also be true in applied practice with athletic populations.
Exercise has been shown to lead to vast inaccuracies in body composition analysis using BIA 21 , as has changes in hydration status As a result, BIA may not be suitable for determining body composition changes due to fluctuations in hydration status following training.
Body composition measurement in vivo is an estimate. As mentioned previously, the cost and practicality of measuring body composition vary greatly, and often there is a trade-off between the two.
Each method has a use in certain settings, and it is the job of the practitioner or user to understand the benefits and drawbacks of each method. A further issue with body composition is often the focus of individuals on their absolute body fat percentage values.
Rather than focusing on an absolute body fat number, it may be of more value to standardise measurement and track changes over time. As measures of body composition are developed, more accurate measurements of FM and FFM can be established in various athletic populations.
This means that future research should aim to determine:. There are a multitude of body composition assessment tools available to the practitioner, each with varying cost, accessibility and accuracy in each population.
It is important to understand the benefits and limitations of each method, and how best to utilise each one in practice. Most assessment tools are useful in various settings, and accuracy can be improved with proper standardisation prior to testing.

However, the strength of the relationships differed among equations used, with an equation developed in by John Faulkner [32] having the strongest relationship with DXA [29].
The results from these studies demonstrate the lack of agreement between equations, and inconsistent outcomes when compared with more precise body composition assessment methods, such as DXA. As demonstrated by Zemski et al. Substantial intra- and inter-observer variability exists [35, 36].
For example, varying the skinfold site by as little as 1 centimeter can produce significantly different results when experienced practitioners measure the same participant [7, 40]. The research regarding which skinfold equation s most accurately predict body fat percentage in athletes is inconsistent, at best.
Factors including age, sport, race, gender, and others, appear to impact equation validity. However, skinfold assessment can also be quite reliable and should be considered as a convenient, practical indicator of intra-individual regional and total body composition change over time.
Although 3-site and 7-site skinfold equations are similar in accuracy, I lean towards collecting data on more sites. In the case that a novel, highly accurate equation is developed, the practitioner will be better suited to apply the novel, more accurate equation with his or her data set.
