title: Awareness of fifth metatarsal stress fractures among soccer coaches in Japan: A cross-sectional study

description: Although a fifth metatarsal stress fracture is the most frequent stress
 fracture in soccer players, awareness of fifth metatarsal stress fractures
 among soccer coaches is unclear. Therefore, we performed an online survey
 of soccer coaches affiliated with the Japan Football Association to assess
 their awareness of fifth metatarsal stress fractures. A total of 150
 soccer coaches were invited for an original online survey. Data on
 participants’ age, sex, types of coaching licence, coaching category,
 types of training surface, awareness of fifth metatarsal stress fractures,
 and measures employed to prevent fifth metatarsal stress fractures were
 collected using the survey. Data from 117 coaches were analysed.
 Eighty-seven of the 117 coaches were aware of fifth metatarsal stress
 fractures; however, only 30% reported awareness of preventive and
 treatment measures for fifth metatarsal stress fractures. Licensed coaches
 (i.e., licensed higher than level C) were also more likely to be aware of
 fifth metatarsal stress fractures than unlicensed coaches were.
 Furthermore, although playing on artificial turf is an established risk
 factor for numerous sports injuries, soccer coaches who usually trained on
 artificial turf were more likely to be unaware of the risks associated
 with fifth metatarsal stress fractures than coaches who trained on other
 surfaces were (e.g., clay fields). Soccer coaches in the study population
 were generally aware of fifth metatarsal stress fractures; however, most
 were unaware of specific treatment or preventive training strategies for
 fifth metatarsal stress fractures. Additionally, coaches who practised on
 artificial turf were not well educated on fifth metatarsal stress
 fractures. Our findings suggest the need for increased awareness of fifth
 metatarsal stress fractures and improved education of soccer coaches
 regarding injury prevention strategies.　
description: A computer-based survey was created following a literature review
 of the injury, treatment, and prevention of MT-5 and a discussion with
 experienced physical therapists, sports medicine physicians, and sports
 scientists who were familiar with MT-5. The final version of the
 questionnaire was established through consensus among all members to
 encompass all relevant aspects of MT-5. This study’s main interest was to
 understand differences in the awareness about the injury, treatment, and
 prevention of MT-5 by licence level and coaching environment. Hence, the
 questionnaire was designed with an emphasis on how many coaches were aware
 of this information rather than the depth of their knowledge of MT-5. A
 research request was sent to potential respondents who provided consent.
 Each participant entered the mobile terminal using a personalised code.
 The exclusion criteria were failure to provide informed consent to
 complete the survey. Additionally, if more than one incomplete response in
 the questionnaire was confirmed, all the individual’s data were excluded
 from the analysis.

 [https://doi.org/10.5061/dryad.n5tb2rc3g](https://doi.org/10.5061/dryad.n5tb2rc3g) This data assesses awareness of the fifth metatarsal stress fracture among soccer coaches. The awareness of fifth metatarsal stress fracture tend to increase, depending on the level of coaching license. Although the incidence of fifth metatarsal stress fracture has been reported to be related to the frequency of artificial turf use, it was found that approximately 40% of coaches who usually use artificial turf in training were unaware of fifth metatarsal stress fractures. ## Description of the data and file structure This data is a xisx file. LC is the licence held. (None 0, Class D 1, Class C 2, Class B 3, Class A 4, Class S 5, Other 6) FCC is the football coaching category. (Elementary 0, Junior High 1, High School 2, University 3, Amateur 4, Professional 5) TGS is the type of ground you are coaching on. (artificial turf 0, cray 1, artificial turf 2) FFC is the frequency of football coaching. (once a week 0, twice a week 1, three times a week 2, four times a week 3, five times a week 4, six times a week 5, seven times a week 6) AHC is the average hours of coaching per session. (0 under 60 minutes, 1 60-90 minutes, 2 90-120 minutes, 3 over 120 minutes) AMT-5 is the awareness of fifth metatarsal stress fracture (MT-5). (yes 0, no 1) MT-5 TR shows whether MT-5 treatment is recognised. (yes 0, no 1) MT-5 TP shows whether MT-5 prevention training is provided. (yes 0, no 1) OP gives an open-description of the preventive training method being implemented. ## Sharing/Access information N/A * ## Code/Software N/A
