Abstract：
(1) Background: The physical fitness (PF) of hearing-impaired students has always been an international research hotspot since hearing-impaired students have difficulty in social interactions such as exercise or fitness programs. Sports interventions are proven to improve the fitness levels of hearing-impaired students; however, few studies evaluating the influence of Cha-cha (a type of Dance sport) training on the PF levels of hearing-impaired students have been conducted. (2) Purpose: This study aimed to intervene in hearing-impaired children through 12 weeks of Cha-cha dance training, evaluating its effects on their PF-related indicators, thus providing a scientific experimental basis for hearing-impaired children to participate in dance exercises effectively. (3) Methods: Thirty students with hearing impairment were randomly divided into two groups, and there was no difference in PF indicators between the two groups. The Cha-cha dance training group (CTG, n = 15) regularly participated in 90-min Cha-cha dance classes five times a week and the intervention lasted a total of 12 weeks, while the control group (CONG, n = 15) lived a normal life (including school physical education classes). Related indicators of PF were measured before and after the intervention, and a two-way repeated-measures analysis of variance was performed. (4) Results: After training, the standing long jump (CONG: 1.556 ± 0.256 vs. CTG: 1.784 ± 0.328, p = 0.0136, ES = 0.8081), sit-and-reach (CONG: 21.467 ± 4.539 vs. CTG: 25.416 ± 5.048, p = 0.0328, ES = 0.8528), sit-ups (CONG: 13.867 ± 4.912 vs. CTG: 27.867 ± 6.833, p < 0.0001, ES = 2.4677) and jump rope (CONG: 52.467 ± 29.691 vs. CTG: 68.600 ± 21.320, p = 0.0067, ES = 0.6547) scores showed significant differences. (5) Conclusions: After 12 weeks of Cha-cha dance training for hearing-impaired students, the PF level of hearing-impaired students in lower-body strength, flexibility, core strength, and cardiorespiratory endurance were effectively improved; however, there was no significant change in body shape, upper-body strength, vital capacity, and speed ability.
摘要：
(1)背景:由于听障学生在运动或健身项目等社会交往中存在困难,因此听障学生的身体素质(PF)一直是国际研究热点。体育干预被证明可以提高听力受损学生的健身水平；然而，很少有研究评估Cha-cha（一种舞蹈运动）训练对听力受损学生PF水平的影响。(2)目的:本研究旨在通过12周的Cha-cha舞蹈训练对听障儿童进行干预,评估其对PF相关指标的影响，从而为听障儿童有效参与舞蹈练习提供科学的实验依据。(3)方法:将30名听力障碍学生随机分为两组,两组PF指标无差异。Cha-cha舞蹈训练组（CTG，n=15）每周定期参加五次90分钟的Cha-cha舞蹈课，干预总共持续了12周，而对照组(CONG，n=15）过着正常的生活（包括学校体育课）。干预前后测定PF相关指标,并进行了双向重复测量方差分析。(4)结果:经过培训,站立跳远（CONG：1.556±0.256vs.CTG:1.784±0.328,p=0.0136,ES=0.8081),坐达（CONG：21.467±4.539vs.CTG:25.416±5.048,p=0.0328,ES=0.8528),仰卧起坐（CONG：13.867±4.912vs.CTG：27.867±6.833，p<0.0001，ES=2.4677）和跳绳（CONG：52.467±29.691vs.CTG:68.600±21.320,p=0.0067,ES=0.6547)评分有显著性差异。(5)结论:听障学生经过12周的Cha-cha舞蹈训练,听力受损学生下半身力量的PF水平，灵活性,核心强度,心肺耐力得到有效改善；然而，身体形态没有明显变化,上身强度,肺活量,和速度能力。
