Physical Description:


Adults with intellectual disabilities (IDs) struggle more so than typically developed individuals (TDIs) in both physical activity and cognitive ability relating to daily tasks. Evidence shows that regular physical activity can have a positive impact on quality of life in intellectuals without disabilities. This study focused on expanding the understanding of this phenomenon in students with ID, both male and female by utilizing a known positive correlation between improvement in fitness and decreased recovery heart rate. Young adults with ID were involved in a peer-mentor functional training (FT) program for years (fall/spring semesters) and their recovery heart rate was obtained and compared before and after the physical fitness intervention each semester. The intervention design kept the participants’ heart rates in the aerobic zone (60-70% of the maximum heart rate). Results show that participants involved in the study showed decreases their recovery heart rate compared to the recovery heart rate obtained before the intervention, indicating regular physical fitness could have a positive impact in the health of adults with IDs.

Introduction Purpose Methods Results Conclusion Martina Diaz Bobillo, Kevin Stepanek, Chelsea Stewart, B.S, Tony Delisle, Ph.D ., Mona Sayedul Huq, M.S., Christine Stopka, Ph.D. College of Health and Human Performance, University of Florida, Gainesville, FL Future Direction Adults with intellectual disabilities (IDs) struggle more so than typically developed individuals (TDIs) in both physical activity and cognitive ability relating to daily tasks. They also have lower rates of physical activity, cardiorespiratory fitness, and muscular endurance which lead to higher rates in secondary conditions such as diabetes, hypertension, heart disease, etc. Studies have shown the potential health benefits in adults without IDs after consistent physical exercise. Heart Rate is commonly utilized as a measure of cardiorespiratory fitness. Decrease in recovery heart rates are observed along with consistent exercise which is an indicator that the heart of an individual is able to pump more blood per contraction, therefore needing less beats per minute. This study focused on understanding how moderate physical activity can impact the health of young adults with IDs using a physical fitness intervention program. The study examines different types of exercise used in a program from Fall 2009 to Spring 2014. The physical fitness training programs have included approximately 20 30 participants with IDs ranging in ages from 16 22 years old. Each program has extended over both fall and spring semesters, lasting 1 hour, twice a week, from 8 10 weeks per semester. Each program ran over the course of two consecutive semesters and recovery heart rates were obtained for each semester (fall/spring) and subsequently calculated for each year Changes in recovery heart rate (RHR) taken during pretests and posttests measured improvements in cardiovascular capacity .The percentage of decrease in RHR was calculated and these values were compared amongst each year and each type of program. Influence of an Exercise Intervention on Recovery Heart Rates of Young Adults with Intellectual Disabilities The program continues to grow and in this current semester has expanded to incorporate students from not only the Sidney Lanier School, but students with various ID that attend Santa Fe college. Repeated physical exercises via weight machines that focus on increasing strength and muscular endurance. Resistance Weight Training (RWT) 2009 2011 FT program that included major functional movements and minor resistive movements by adding free weight to the functional movements. Resistance Weight Training (RWT)/ Functional Training (FT) 2011 2012 Progressive and individualized activities using weight bearing, multiplanar exercises, designed to improve performance of activities of daily living.

Summarized Program Focus and HR Results Fall 2014 To compare cardiovascular capacity improvements using RHR measurements of an fitness intervention using different forms of exercise on young adults with ID, aged 18 to 22, from Fall 2009 to Spring 2014 The form of exercise changed significantly through the years; currently, its focus lies within functional training. The shift occurred because of lack of accessibility, affordability, and availability of resistance training equipment and programs. F unctional training, which involves weight bearing, multi planar exercises designed to improve performance of activities in daily living, provided a cost effective, readily accessible solution. To obtain a measure of cardiorespiratory fitness between Fall 2009 to Spring 2011 the students participated in the Harvard step test and their recovery heart rates were obtained. For Fall 2011 to Spring 2014 the YMCA 3 minute step test was used to obtain the recovery heart rates. During pre/posttesting, various assessments utilized allowed for better comprehension of the overall improvement of fitness measure. For this study, heart rate was chosen for analysis as it provides the direct reflection of changes in cardiovascular capacity. The results of this study show that significant decreases can be noted in the recovery heart rates pre/post test regardless of the program. This appears to uphold the beliefs that functional training in individuals with ID can reduce RHR. Research shows that individuals with intellectual disabilities have higher rates of conditions such as obesity, hypertension, and chronic illnesses For years, the aim of this program was to show how routine physical fitness can improve overall fitness in individuals with ID, aid in reducing the instance of the conditions discussed above, and promote functional independence.
