The scholarly journal Measurement and Control published a study about a certain class of persons who measure and control the activities of a certain other class of persons:
“Body Composition in Spanish Soccer Referees.” J.A. Casajus, A. Matute-Llorente, H. Herrero, and A. González-Agüero, Measurement and Control, vol. 47, no. 6 (2014): 178-184. (Thanks to investigator John Pullin for bringing this to our attention.) The authors, at the University of Zaragoza and the Royal Spanish Football Federation, report:
[We examined the] body fat of elite Spanish soccer referees and assistant referees by division, role and age group. Participants were 243 males (age 32.4 ± 5.3 years, weight 72.3 ± 6.2 kg, height 179.1 ± 5.9 cm and body mass index 22.5 ± 1.4) who belonged to the Referees Technical Committee of the Royal Spanish Soccer Federation…. they were divided into three age groups as previously described by Castagna: young (Y, 27–32 years, n = 144), average (A, 33–38 years, n = 66) and senior (S, 39–45 years, n = 33)…. These results showed that first- and second-B-division referees presented more healthy values of %BF than first- and second-division assistants. By age group, Y group had the lowest %BF.
