“…In men specifically, evidence suggests that increased leg length relative to height is an intersexually selected cue of health (i.e., it is attractive to women; reviewed in Bogin & Varela-Silva, 2010;Sorokowski, 2010). Contrasting to this, women do not show a preference for men with longer arms relative to body length (Versluys, Foley, & Skylark, 2018). Analyses of skeletal remains suggests that arm length, particularly upper arm length, is not as sensitive to nutrition and disease as leg length is (Jantz & Jantz, 1999;Meadows & Jantz, 1995) which undermines its validity as a health cue.…”

Growing evidence suggests that human males have been sexually selected for violent contest competition. I propose the hypothesis that increased arm length is an intrasexually selected adaptation for fighting in males. Longer arms may have provided several advantages to our male ancestors during conflict. However previous research on the effects of arm span on fighting success have shown mixed results and may not have fully accounted for allometric scaling of arm span with size. In a sample of 1,660 modern mixed martial arts fighters, I find that arm span is sexually dimorphic and associated with fighting success, even when controlling for body size. However, effects of arm span on fighting success were very small, suggesting that selection may have been weak. I review evidence for alternative explanations for men’s longer arm span and propose future directions to further test this hypothesis.

“…Versluys et al have shown that AL is proportional to forearm length with an intra-limb ratio of 0.817, which suggest that upper AL may be used for a preoperative assessment of tibial nail length. 12 This study shows that AL had the least average difference to nail length for all observations made with narrow limits of agreement. On repeatability assessment using the BlandAltman method, we found that AL showed a difference of −0.02 mm on average when measured by different observers and the limits of agreement at −19.04 to 19.01, indicating good repeatability.…”

A bstract Aim and objective To assess the use of arm length (AL) for the estimation of tibial nail length preoperatively and compare its accuracy to various established upper and lower limb anthropometric parameters. Material and methods This prospective study of 54 patients assessed upper limb parameters as a possible alternative for intraoperatively measured tibial nail length. The anthropometric parameters measured independently by two observers were AL, olecranon to fifth metacarpal head (OMD), tibial tuberosity to medial malleolus (TT-MM), tibial tuberosity to medial malleolus minus 20 mm (TT-MM-20 mm) and knee joint line to medial malleolus minus 40 mm (KJL-MM-40) and compared to final nail size used intraoperatively. Two observers were used. Bland-Altman plots were constructed to assess the limits of agreement to intraoperative estimates of optimum nail length. A repeatability assessment was also assessed by both observers. Results None of the anthropometric parameters showed limits of agreement within ±10 mm of nail length. AL showed the least average difference and best limits of agreement among all the anthropometric parameters. Among the lower limb parameters, the KJL-MM showed the least average difference but poorer limits of agreement to nail length. The OMD measurement showed a greater average difference than the AL indicating it is a poorer upper limb parameter for predicting nail length. Conclusion AL as measured between the angle of the acromion to the lateral epicondyle can be used as a preoperative upper limb anthropometric estimate of nail length to one nail size of the optimum length. Further studies with a larger sample size may reduce the confidence intervals and help justify its wider use. How to cite this article Sharma A, Sinha S, Gupta S, et al.

“…The ideal limb can allow a player to move more efficiently. The ideal leg-to-body ratio is at least 1:0.5 [10,11]. The ideal arm span and leg ratio are important requirements in determining talent in basketball.…”

Body shape has an important role in playing basketball. The position of players in basketball can be determined by their height. There is some information that can be inferred from height. Body mass index, the ratio of leg to body length, and the ratio of arm length to height. This is valuable information for extracurricular coaches because they can find out if a player has the ideal body shape as a basketball player. Through this research, it can be seen the body shape of the basketball extracurricular participants in the junior high school category. This research also helps extracurricular trainers to identify extracurricular participants who have the ideal body shape. The method used in this research is a survey using a measuring tape, measuring height and weight. The samples involved in the study were 104 boys and 48 girls with an age range of 12-15 years. The measurements taken were height, weight, arm span, and sitting height. The measurement results show that 55% have an ideal height, 34% have a normal body mass index, 5% have an ideal leg length, and 99% have an ideal arm span. Basketball extracurricular participants at private junior high schools in Sukoharjo have the potential to be hampered in performing movements using the legs and potentially easier to perform movements using the arms.
