The effect of 8 weeks plyometric exercise on physical and motoric features of mental disabled

Abstract

Background and Study Aim. Physical activity for disabled people is a long-debated issue. The number of studies examining the effects of alternative exercise programs on the physical and motor outcomes of people with intellectual disabilities is limited. For this reason, the purpose of this study is to investigate the effects of 8-week plyometric exercises on some physical and motor characteristics of mentally retarded people.
 Material and Methods. The method of this study is the experimental method, one of the quantitative research methods. The sample of the study consists of 24 moderately and mildly mentally retarded students aged 11-17 years old studying at a special vocational school. Participants completed a plyometric training program 3 days per week for 8 weeks. Before the training program, height, weight, BMI, vertical jump, sit and reach, standing long jump, circumference measurements, handgrip strength, shuttle test, leg strength, and back strength were compared with those after the training program. The SPSS 25 program was used for the statistical operations. The Wilcoxon test, one of the non-parametric tests, was used to compare the data.
 Results. As a result of statistical analysis, significant differences were found in height, weight, vertical jump, sit and reach, handgrip strength, shuttle test, leg strength, and back strength of the participants before and after the training program (p < 0.05). There was no significant difference between the body circumference measurements and BMI results (p > 0.05).
 Conclusions. When evaluating the results of the study, it was found that plyometric exercises have a positive effect on the physical and motor characteristics of the intellectually disabled people.

The Impact of Plyometric Training on Agility, Speed, and Social Interaction in Children with Mild Intellectual Disability: A Special Olympics Framework Study

“…Previous research has shown similar benefits of physical activity programs for children with ID. For instance, study by Kurtoğlu et al (2022) explored the effects of an 8-week plyometric exercise program on physical and motor skills in 24 students aged 11-17 with moderate to mild intellectual disabilities. Participants completed the exercises three times a week.…”

Changing the level of mental health and fundamental movement skills on pencak silat athletes through game-based circuit training

“…The instrument for measuring mental health was the DASS-21 with three subscales: (1) depression related to hopeless, passivity, low-selfesteem, dysphoria and anhedonia, (2) anxiety related to feeling of situational anxiety and autonomic arousal and (3) stress related to nervous arousal, relaxing, irritable, and upset [23]. According to Ghani, Zainuddin, Ibrahim, Hashim & Van [51], the depression subscale consisted 3, 5, 10, 13, 16, 17 and 21 question items. Depression with normal levels (0-9), mild (10)(11)(12), moderate (13)(14)(15)(16)(17)(18)(19)(20), severe (21)(22)(23)(24)(25)(26)(27) and very severe (28-42).…”
