In the study conducted by Steele and Chenier (12), the arm span was nearly 8.3cm more than the body height for black population, whereas for white population this difference was only 3.3cm (11). They have noted in their study done on South Indian females, the arm span was nearly 2.5cm higher than stature. In study (13), arm span was 5.8cm more than body height for Nigerian males whereas, for Nigerian females, this difference was only 4cm which is similar to that noted in the white population although they are black. It is a necessity when measuring height is unenviable due to certain medical conditions and in field studies. This study aims to estimate stature from arm span, arm length and tibial length among adolescents of age 15–18 in Ethiopia. The estimation of stature using various anthropometric measurements are quite the age-old investigations over the past centuries and it has been attempted by many authors in many countries.
What is considered a long arm?
Examples of various classes of small arms generally considered long arms include, but are not limited to shotguns, personal defense weapons, submachine guns, carbines, assault rifles, designated marksman rifles, sniper rifles, anti-material rifles, light machine guns, medium machine guns, and heavy machine guns.
All the anthropometric measurements except for weight were measured when the subjects were standing in the Frankfort horizontal plane. To allow for these differences clothing designers measure from the center back of your neck, over the top of your shoulder and down to the point where your hand starts to widen at your wrist. The actual measurement of your arm only is measured from the top of the shoulder to the bottom of your wrist and is often used for casual shirt sizing. It is important that an accurate, consistent, and efficient method of measuring arm span width be established. Here we report on an efficient arm span measurement method that features improved accuracy. Then, using a tape measure, let your partner measure the distance between the fingertip on one hand to the fingertip of the other.
Study participants
Moreover, problems and difficulties in measurement of height can be encountered in field studies compared with clinical settings because of the portability, accessibility, and expense of specialized equipment used for measurement of height. Therefore, surrogate measures of height that can be obtained by simple and portable tools are mandatory. Therefore, most regression formulas derived are meant to be specific for a particular region and can be used only in that particular area https://accounting-services.net/how-to-measure-arm-length-10-steps/ of study and for that particular age group in which the study was conducted. It is indeed, necessary to derive regression equations, which are age group, gender, ethnic, and geographic area specific (3,4). In an epidemiological survey, with a large number of subjects’ indicators, it is especially valuable to establish methods which can measure both quickly and accurately. However, methods used to measure arm span vary among medical institutions, as do the resulting measurements.
However, there are various methods, and the length of arm span may vary according to the medical institution. An above-average reach is advantageous in sports such as basketball, tennis, boxing, mixed martial arts, volleyball, discus throw, fencing, rock climbing, and swimming. However, a long arm span is mechanically disadvantageous on the bench press. Measure from the top of the centre back (nape of the neck) to the end of your shoulder at the top of your arm. Measure from your shoulder to just before the wrist bone or where you would like your cuff to sit.
Arm span
Your reach is usually determined by your height, meaning that taller people tend to have longer reach. But generally, you can assume that Shaquille O’Neal would have a longer reach than Danny DeVito. But outside of just that, there are many other things to consider before sparring against an opponent.
Arm span highly correlates with height and regression equations fitted from arm span was found to be best estimator of height. The strength of prediction of regression equations in general increased with increasing number of anatomical anthropometric parameter and from linear to stepwise multiple regressions. There was no statistically significant mean difference between estimated and actual stature in both male and female study participants.
Estimation of Stature from Arm Span, Arm Length and Tibial Length among Adolescents of Aged 15–18 in Addis Ababa, Ethiopia
Remember that boxers with a long reach will try to keep you at a distance, so you’ll need to fight inside so that they won’t be able to use their arm length to their advantage. Boxing is a sport that is almost entirely dictated by your bodyweight and the ways in which you utilize it. This is why boxing classes are divided based on weight, as it helps to ensure a more even fight. Taking your own sleeve length is one of the tougher body measurements to do on your own.
- There was no statistically significant mean difference between estimated and actual stature in both male and female study participants.
- Written informed consent was obtained from individual mothers prior to their participation.
- MT, AS, SA, MS, KK, and TA critically reviewed the manuscript and supervised the study process.
- Unlike any of the athletic testing drills where lasers, stopwatches, GPS, and slow-motion cameras capture every detail, the NFL keeps it simple when it comes to measuring arm length.
- The nine children were participants in the pilot study cohort of the Japan Environment and Children’s Study, a government-funded prospective birth cohort study in Japan [8].
For infants, it is sometimes difficult to stretch out the fingertips and spread the arms. The use of long bone measurements as an alternative to height in nutritional assessment of the elderly was investigated in 100 young and 63 aged individuals. Highly significant correlations between height and total arm length, humerus length, forearm length, and proximal phalanx length were found. Compared to young subjects, values for the elderly were shifted significantly, demonstrating a reduction in height not paralleled by decreases in arm length measurements. In subsequent studies, lean body mass was evaluated by creatinine excretion in groups of young and elderly male and female volunteers. In both males and females, when creatinine excretion was related to height, ideal body weight, or total arm length, significantly lower values were found in the elderly as compared to the young.
