Then, launch the stone at the same speed, and move according to the sweeping conditions (perpendicular to the axis of motion, along the axis of motion) of male and female elite curlers. The aim is to provide sports science information required for curling athletes by analyzing the distance of the stone, the change in the speed of a moved stone, the change in broom acceleration, and athletes\u2019 muscle activity. The results of experiments conducted on four male and four elite female curlers are as follows. Under gender, the stone\u2019s movement distance was long after the sweeping of male athletes, and the speed of the stone was not different according to the conditions. The broom\u2019s acceleration did not show a difference in both the sweeping condition and the athlete\u2019s gender condition, and the muscle activity did not show a significant difference in both the sweeping condition and the gender condition. In summary, it is thought that male athletes moved the stone farther by raising the ice surface temperature by vertical load than female athletes. Also, there was no statistically significant difference in muscle activity results, but it was found that there was a specific pattern of muscle activity in the pushing and pulling motions during the sweeping of male and female athletes. It is expected to be used as primary data.<\/jats:p>","DOI":"10.3390\/ijerph18020833","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T11:39:55Z","timestamp":1611056395000},"page":"833","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Case Study on Curling Stone and Sweeping Effect According to Sweeping Conditions"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2915-5394","authenticated-orcid":false,"given":"Tae-Whan","family":"Kim","sequence":"first","affiliation":[{"name":"Korea Institute of Sport Science, Seoul 01794, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang-Cheol","family":"Lee","sequence":"additional","affiliation":[{"name":"Korea Institute of Sport Science, Seoul 01794, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Se-Kee","family":"Kil","sequence":"additional","affiliation":[{"name":"Korea Institute of Sport Science, Seoul 01794, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1166-864X","authenticated-orcid":false,"given":"Sang-Hyup","family":"Choi","sequence":"additional","affiliation":[{"name":"Center for Sport Science in Jeju, Jeju 63189, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong-Gwan","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Marine Sports, Pukyong National University, Busan 48513, Korea"},{"name":"Department of Marine Design Convergence Engineering, Pukyong National University, Busan 48513, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"268","DOI":"10.24985\/kjss.2014.25.2.268","article-title":"Comparative Analysis of the Change CoM Displacement, CoM Velocity, and Foot-Pressure in Draw and Takeout Curling Skills","volume":"25","author":"Kim","year":"2014","journal-title":"Korean Inst.
