Effects of Nonperiodized and Linear Periodized Combined Training on Health-Related Physical Fitness in Adults With Obesity: A Randomized Controlled Trial.

Streb, AR, Passos da Silva, R, Leonel, LdS, Possamai, LT, Gerage, AM, Turnes, T, and Del Duca, GF. Effects of nonperiodized and linear periodized combined training on health-related physical fitness in adults with obesity: a randomized controlled trial. J Strength Cond Res 36(9): 2628-2634, 2022-The aim of this randomized controlled trial study was to compare the effects of 16 weeks of linear periodized and nonperiodized combined training (CT) in cardiorespiratory fitness, muscle strength, and body composition indicators of adults with obesity. Thirty-four obese adults of both sexes (36.6 ± 4.4 years; body mass index, 32.9 ± 2.7 kg·m -2 ) were divided into nonperiodized (NG; n = 8), linear periodized (PG; n = 11), and control (CG; n = 15) groups. The NG and PG groups performed 3 weekly sessions of CT over 16 weeks in different ways. Anthropometric measures, maximal strength for leg press and barbell bench press, maximal oxygen uptake (V̇ o2 max), and ventilatory thresholds were determined before and after intervention. The generalized estimation equation was used, with the applied level of significance for the interaction of 0.10 and the isolated effect of time or group or both of 0.05. Significant and similar increases were observed in the 1-repetition maximum test for bench press (NG: 48.8 ± 5.7 to 55.0 ± 6.1 kg; PG: 48.7 ± 5.7 to 53.8 ± 5.9 kg; p = 0.001) and leg press (NG: 235.2 ± 18.7 to 268.3 ± 19.7 kg; PG: 223.1 ± 25.3 to 253.3 ± 23.1 kg; p = 0.05) in trained groups. Relative V̇ o2 max improved only in PG (27.8 ± 1.3 to 32.0 ± 1.4 mL·kg·min -1 ; p = 0.05), while ventilatory thresholds improved in NG and CG ( p = 0.004 and p = 0.06). There was an increase in body mass in CG (97.6 ± 3.4 to 99.1 ± 2.9 kg) and NG (92.5 ± 5.4 to 93.5 ± 5.4 kg; p = 0.05). Combined training improved maximal upper-body and lower-body strength, regardless of periodization. However, for improvement in V̇ o2 max, linear periodization may be superior to nonperiodization in obese adults.

Phase angle associated with different indicators of health-related physical fitness in adults with obesity

In obese populations, the exacerbated increase in adipose tissue results in a significant reduction of health-related physical fitness and can affect the phase angle (PhA), a promising health indicator of cell health and integrity. The aim of this study was to investigate the association of PhA with health-related physical fitness indicators in obese adults. This cross-sectional study had a non-probabilistic sample and was conducted from April to June 2018. The PhA was obtained by a bioelectrical impedance analysis, and the health-related physical fitness indicators evaluated were percentage of body fat (%BF), lower- and upper-body maximal strength, cardiorespiratory fitness (relative V̇O2peak), and flexibility. Pearson and Spearman´s linear correlations, crude and adjusted linear regression analyses were performed. A total of 69 obese adults (60.8% female; BMI = 33.5 ± 2.8 kg/m2) with a mean age of 34.6 ± 7.1 years were studied. The PhA means were 5.8 (±0.6º) and had an inverse correlation with %BF (r=−0.74; p<0.001) and positive correlation with V̇O2peak (r=0.50; p<0.001), lower- and upper-body maximal strength (r=0.65; r=0.70; p<0.001, respectively). After adjustment, %BF (β=−0.065, adjusted R2=0.53; p<0.001), lower- and upper-body maximal strength (β=0.004; adjusted R2=0.46; p<0.001, and β=0.024; adjusted R2=0.50; p<0.001, respectively) were predictors of PhA. Our results suggest the favorable role of PhA as a clinically viable tool to screen and identify the physical fitness variables and functional status of obese adults.

Feasibility and reliability of the Assessing Levels of Physical Activity health-related fitness test battery in adults with intellectual disabilities.

People with intellectual disabilities (IDs) seem to have a lower physical fitness (PF) than their peers without disabilities, which coincides with reduced autonomy, life expectancy and quality of life. To assess PF in these individuals, it is necessary to use appropriate tools that permit the assessment of their physical capacities taking into account their specific characteristics. The aim of this work is to study the feasibility and reliability of the Assessing Levels of Physical Activity (ALPHA)-Fit test battery for adults in a group of men and women with mild to moderate ID. Forty-one adults with ID of both sexes, ranging in age from 20 to 60years old, participated in the study. To identify the feasibility and reliability of the ALPHA-Fit test battery for adults, two complete assessments were done for each one of the tests included in the battery. The assessments were performed for a period of no more than 2weeks (test-retest). An intraclass correlation coefficient was used to determinate test-retest reliability, and a mixed analysis of variance factorial was used for each of the dependent variables. Bland-Altman plots were also used to assess consistency between the two measurements. Feasibility was calculated as the percentage of people who were able to perform the tests correctly (not feasible <50%, fairly feasible 50%-75% and feasible >75%). In order to determine other psychometric properties, minimal detectable change and standard error of measurement (SEM) were also calculated. Of the 10 tests in the ALPHA-Fit test battery, eight were shown to be feasible. High reliability was obtained (>0.90) for the variables related to body composition. In the hand-grip test, reliability was high in the men's group but low in the women's group. Good reliability results were also found (0.80-0.89) in the dynamic sit-up test for women, but not for men. Fair reliability (0.70-0.79) was found in jump-and-reach and neck-shoulder mobility tests. The variables in the 2-km walk and agility tests indicated poor reliability. All tests showed SEM values related to high variability. However, Bland-Altman plots showed results related to lack of consistency. The feasibility and reliability calculations, as well as the SEM values, confirm that not all the tests of the ALPHA-Fit Test Battery for Adults are suitable for the assessment of PF in adults with ID, probably because of the complexity of the motor fitness tests. The authors emphasise the necessity of making adaptations to the protocols used or of using other tests more appropriate to the characteristics of people with mild to moderate ID.

Excessive body weight versus physical fitness in adults with moderate and severe intellectual disabilities

An increasing number of people with intellectual disabilities (ID) are characterized by an excess of body weight. The impact of overweight and obesity on motor skills in this population is ambiguous. The study aimed to review the impact of overweight and obesity on the physical fitness of adults with intellectual disabilities. The study covered 128 people with ID: 70 women (W) and 58 men (M); 62 people with moderate intellectual disabilities and 66 people with severe intellectual disabilities. The following measurements were taken: body mass (BM), body height (BH), and waist circumference (WC). BMI was calculated. The physical fitness level was assessed with the Eurofit Special test. Obesity and overweight were found in 37% and 24% of W and 39% and 22% of M respectively; in 40% and 17% of people with moderate ID and 36% and 28% of people with severe ID respectively. Significant negative correlations between speed and BMI and WC, and between core muscle strength and WC were found in women. In men, negative correlations were found: between core muscle strength and BM, BMI, and WC; between flexibility and BM, BMI, and WC; between lower extremity muscle strength and BMI and WC; and between balance and BMI. Further, obese men had significantly lower scores compared to the normal weight sample in the following tests: balance (T1), lower extremity muscle strength (T2), speed (T4), and core muscle strength (T6). The study showed a relationship between obesity and scores in physical fitness tests. More relationships were found in men than women and in people with severe ID than moderate ID.

Feasibility and reliability of a physical fitness tests battery for adults with intellectual disabilities: The SAMU DIS-FIT battery

BackgroundPeople with intellectual disability (ID) have lower performances in physical fitness (PF) tests than people without ID, a situation that exists during all the life stages. However, the assessment of the FP of persons with ID often uses instruments that were designed for non-disabled people. AimTo check the reliability and feasibility of 8 PF tests in adults with mild to moderate ID. MethodsA cross-sectional study was carried out with a test-retest design in a maximum interval of 2 weeks with 240 adults (160 men and 80 women) with mild to moderate ID in order to assess the feasibility and reliability of the following 8 tests: body mass index (BMI), waist circumference (WC), the timed up & go test (TUG), the deep trunk flexion test (DTF), the hand grip test (HG), the timed stand test (TST), the 30-s sit-up (SUP) test, and the 6-min walk test (6MWT). The complete battery was called the SAMU-Disability Fitness Battery (SAMU-DISFIT). The psychometric properties of the battery, feasibility, reliability, the standard error of the measurement (SEM) and the minimal detectable change (MDC) were calculated. ResultsThe TUG, DTF, HG, TST, and 6MWT showed an intraclass correlation coefficient (ICC) from fair to high reliability. Only the SUP test in men had an ICC lower than 0.7 and high SEM values. ConclusionThe psychometric properties provide robust data on the use of the SAMU-DISFIT battery in people with ID and can be considered a useful tool for assessing PF in adults with mild to moderate ID in future research.

Quantitative Physical Fitness Measures Inversely Associated With Myopia Severity in Military Males: The CHIEF Study.

Myopia has been linked to body weight and sedentary status, but the association with quantitatively measured physical fitness in adults has not been examined. Cross-sectional analyses were performed to investigate the association between physical fitness and myopia in 3,669 military men (aged 29.4 years) in Taiwan. The severity of myopia obtained from the left eye was classified as mild (−0.5 to −3.0 diopters; n = 544), moderate −3.1 to −6.0 diopters; n = 563), and high (<−6.0 diopters; n =150); others were defined as nonmyopia (n = 2,412). Aerobic fitness was evaluated by time for a 3000-meter run test, and muscular endurance was evaluated by numbers of 2-min sit-ups and 2-min push-ups. A value of p < .0125 was considered significant. A multiple linear regression analysis was used to determine the relationship. Individuals who were less physically fit had higher risk of myopia. The associations were dose-dependently significant with mild, moderate, and high myopia for 3000-meter running time (β = 9.64; 95% confidence intervals [3.22, 16.05], β = 12.41; 95% CI [6.05, 18.76], and β = 20.87; 95% CI [9.22, 32.51], respectively) after controlling for the potential covariates. There tended to be an inverse association with moderate and high myopia for numbers of 2-min push-ups (β = −1.38; 95% CI [−2.43, −0.34] and β = −2.10; 95% CI [− 3.97, −0.22], respectively) and 2-min sit-ups (β = −0.83; 95% CI [−1.54, −0.12] and β = −1.29; 95% CI [−2.56, −0.02], respectively), respectively. This study suggested that physical fitness, particularly aerobic fitness of the military males who received regular training, is inversely associated with myopia severity, independent of service specialty, body mass index, and educational level.

Comparison of linear periodized and non-periodized combined training in health markers and physical fitness of adults with obesity: Clinical trial protocol

The literature discusses that combined training, aerobic more resistance exercises in the same session, is a suitable strategy for people with obesity and that exercise periodization leads to positive health outcomes; however, the implication of different periodizations of combined training for health outcomes in obese adults requires further investigation. The aim of the study will be to describe the methodology used to compare the effect of linear periodized and non-periodized combined training on health markers and health-related physical fitness in adults with obesity. This is a blinded randomized controlled clinical trial investigating adults with obesity in the age group 20–50 years. The sample will be non-probabilistic, and participants will be allocated randomly into one of three groups: control group (CG), non-periodized group (NG), and periodized group (PG). The intervention will occur in 60-min sessions, 3 days a week for 16 weeks, with 1 week dedicated to familiarization with the training and 15 weeks of combined training (aerobic followed by resistance in the same session). The PG group will perform three mesocycles of 5 weeks each, progressing in intensity throughout the intervention [aerobic: from 40-49% to 60–69% of heart rate reserve (HRR); strength: from 12 to 14 maximum repetitions (MR) to 8 to 10MR]; the NG group will maintain the same relative intensity throughout the study (aerobic: 50–59% of HRR; strength: 2 sets of 10–12 MR). Participants in the CG group will maintain their usual activities without the proposed intervention. Pre- and post-intervention assessments will be performed for biochemical markers, body composition, cardiovascular parameters, cardiorespiratory fitness, maximum upper and lower limb strength, flexibility, and subjective health-related parameters. This project was approved by the Committee of Ethics and Research with Human Beings of the institution of origin (protocol 2,448,674) and registered in the Brazilian Registry of Clinical Trials (RBR-3c7rt3).

Adding meaning to physical fitness test results in individuals with intellectual disabilities

Purpose: Evaluating physical fitness in individuals with intellectual disabilities (ID) is challenging, and a multitude of different versions of tests exist. However, psychometric properties of these tests are mostly unknown, and both researchers as clinical practitioners struggle with selecting appropriate tests for individuals with ID. We aim to present a selection of field tests with satisfactory feasibility, reliability, and validity, and of which reference data are available.Methods: Tests were selected based on (1) literature review on psychometric properties, (2) expert meetings with physiotherapists and movement experts, (3) studies on population specific psychometric properties, and (3) availability of reference data. Tests were selected if they had demonstrated sufficient feasibility, reliability, validity, and possibilities for interpretation of results.Results: We present a basic set of physical fitness tests, the ID-fitscan, to be used in (older) adults with mild to moderate ID and some walking ability. The ID-fitscan includes tests for body composition (BMI, waist circumference), muscular strength (grip strength), muscular endurance (30 second and five times chair stand), and balance (static balance stances, comfortable gait speed).Conclusions: The ID-fitscan can be used by researchers, physiotherapists, and other clinical practitioners to evaluate physical fitness in adults with ID. Recommendations for future research include expansion of research into psychometric properties of more fitness tests and combining physical fitness data on this population in larger datasets.Implications for rehabilitationIndividuals with intellectual disabilities have low physical fitness levels, and a high risk for unnecessary functional decline and unhealthy aging.Physical fitness testing could help improve, adapt and evaluate exercise interventions, but is challenging in this population.This paper proposes a selection of tests (ID-fitscan) with sufficient feasibility, reliability, and validity in this population, and provides reference values to aid interpretation of physical fitness test outcomes in individuals with intellectual disabilities.The ID-fitscan can be used by researchers, physiotherapists, and other clinical practitioners to evaluate physical fitness, and thereby allowing for a better interpretation of results by using the same tests, and an increasing knowledge of the physical fitness levels of this population.

Feasibility of a dance and exercise with music programme on adults with intellectual disability.

Research regarding the feasibility and effects of dancing and exercise with musical support programmes on the physical fitness of adults with intellectual disability (ID) is scarce. The purpose of this study was to provide scientific evidence regarding the feasibility of a training programme consisting of dancing and exercise with music designed for adults with ID, as well as to assess its impact on their body composition and cardiovascular and muscular fitness. A total of 30 adults (mean age 36.37±11.24years) with mild (n=13), moderate (n=16) or severe (n=1) ID took part in a 10-week dancing and exercise with music programme. Recruitment and completion rate, adherence to the programme, participation and adverse effects were registered as measures of feasibility. The body mass index, cardiovascular endurance (6-min walk test) and muscular strength (standing long jump test) of the participants were assessed in order to determine the effects of the programme on their fitness level. A 92.5% recruitment rate and a 90% completion rate were achieved. Adherence to the programme stood at 76.6%, and no adverse effects were registered. The comparison between the values obtained in the initial and final evaluations indicated the existence of positive changes in all the fitness dimensions measured. A training programme combining dancing and exercise with music proved to be feasible when performed by adults with ID. These kind of programmes can have a positive effect on the fitness level of this specific group.

Physical Activity and Physical Fitness of Adults with Intellectual Disabilities in Group Homes in Hong Kong.

Adults with intellectual disabilities (ID) typically have a sedentary lifestyle and higher rates of overweight and obesity. This study describes the habitual daily physical activity (PA) and the health-related physical fitness (PF) of adults with mild and moderate ID who resided in four group homes and worked in sheltered workshops. We also assessed the contribution of PF variables towards PA levels and sedentary behavior of this population subgroup. Adults with mild and moderate ID (N = 114) were assessed on PF tests (percent body fat, waist and hip circumferences, 6-min walk (6MWT), arm curl, and sit and reach). PA and sedentary behavior on weekdays were determined using Actigraph accelerometers. Results showed these adults averaged 2% of their daily time (or 10 min) engaged in moderate-to-vigorous PA (MVPA) and 67% of the time (495 min) being sedentary. No significant differences between mild and moderate ID were found for any PA or PF variable. Linear multiple regression analyses showed 6MWT to be the only significant PF variable contributing to the variance of PA and sedentary behavior. In conclusion, adults with ID reside in group home have low PA and low fitness levels. Among fitness variables, the walking test (i.e., cardiovascular fitness) had the highest positive association with participants’ daily PA, MVPA, and negative association with sedentary behavior. Future intervention studies in promoting PA and fitness for adults with ID are warranted.

The effect of 12 weeks of water-aerobics on health status and physical fitness: An ecological approach.

The main purpose of the present study was to verify the effects of a 12-week water aerobics program in a real-life context on health indicators and physical fitness in adults and older adults. Fifteen volunteers (58.80 ± 14.32 years old) were part of an experimental group (Exercise), and eight volunteers (59.00 ± 12.26 years old) were part of the control group (Control). The Exercise performed 45 min of water aerobics twice a week for 12 weeks; no physical exercise was permitted for the Control during the same period. The evaluations were performed the week before (pre-training) and after the training program (post-training). The primary outcomes were the strength and cardiorespiratory fitness variables and the secondary outcomes included body anthropometry, lipid profile and blood pressure. Adjusted analysis for age and baseline values showed no differences between Exercise and Control in post-training moment. However, there was a moderated tendency for increased explosive strength of the upper limbs (ηp2 = 0.17), reduced body fat (ηp2 = 0.17), reduced systolic blood pressure (ηp2 = 0.14) and triglycerides (ηp2 = 0.19) in Exercise. Within groups changes showed that the training program caused an increase mainly in explosive strength in the upper limbs (0.26 m, 95% CI, 0.03, 0.49; ES = 0.63) In addition, there was a significant decrease in fat mass (-0.89%, 95% CI, -1.74, -0.03; ES = 0.61) and in the systolic blood pressure (-0.83 mmHg, -1.46, -0.19; ES = 0.71). Nonetheless, no significant changes were observed for the lipid profile. These results suggest that 12 weeks of water aerobics performed twice a week in a real-life context seem to benefit the explosive strength, body composition, and blood pressure of adults and older adults but is insufficient to alter cardiorespiratory fitness and lipid profiles.

The association between gait and physical fitness in adults with intellectual disabilities.

Gait deviations are often seen in adults with intellectual disabilities (ID). Their low physical fitness levels may be associated with these deviations. Understanding the impact of fitness on gait in this population is important for developing interventions to improve gait. In a cross-sectional study, we assessed the association between multiple physical fitness components and spatiotemporal gait parameters in adults with ID. Gait characteristics of 31 adults (42.77±16.70years) with ID without Down syndrome were assessed with the GAITRite at comfortable (CS) and fast speed (FS), along with fitness assessments (body composition, muscular endurance, strength, balance, Short Physical Performance Battery). At CS, adults with ID with higher BMI and/or waist circumference spent more time in double support. At FS, those with better muscular endurance took steps faster, those with better balance took bigger steps and strides and those with better Short Physical Performance Battery scores took bigger steps and strides at higher velocity. Body composition was mostly associated with gait at CS, while the other physical fitness components were mostly associated with gait at FS. Better fitness may therefore be more important in more challenging conditions. These insights are useful for developing interventions to improve gait in adults with ID.

BMI, leisure-time physical activity, and physical fitness in adults in China: results from a series of national surveys, 2000–14

Obesity, physical inactivity, and reduced physical fitness contribute to the rising burden of chronic diseases in China. We investigated these factors in Chinese adults over a 14-year period (2000-14) using data from randomised national surveys. We did four national surveys in 2000, 2005, 2010, and 2014 among Chinese adults aged 20-59 years. We used BMI to assess underweight (<18·5 kg/m(2)), overweight (≥23·0 to <27·5 kg/m(2)), and obesity (≥27·5 kg/m(2)). Central obesity was defined as a waist circumference greater than 90 cm in men and greater than 85 cm in women. We assessed leisure-time physical activity (LTPA) by whether or not participants had completed the recommended minimum 150 min of moderate or 75 min of vigorous exercise per week. Indices for assessment of physical fitness were forced vital capacity, resting heart rate, hand grip strength, sit and reach distance, and time standing on one leg. 151 656 (78%) of 193 440 adults responded to the survey in 2000, 163 386 (84%) in 2005, 154 931 (80%) in 2010, and 146 703 (76%) in 2014. The prevalence of obesity increased from 8·6% in 2000, to 10·3% in 2005, 12·2% in 2010, and 12·9% in 2014 (estimated increase 0·32% per year, 95% CI 0·30-0·33; p<0·0001). The equivalent estimates were 37·4%, 39·2%, 40·7%, and 41·2% for overweight (estimated increase 0·27% per year, 95% CI 0·25-0·30; p<0·0001) and 13·9%, 18·3%, 22·1%, and 24·9% for central obesity (estimated increase 0·78% per year, 0·76-0·80; p<0·0001). The prevalence of overweight, obesity, and central obesity increased with age (all p<0·0001) and was higher in men than in women (all p<0·0001). We noted a simultaneous decrease in the prevalence of underweight (estimated decrease of 0·06% per year, 95% CI 0·04-0·07; p<0·0001). The proportion of adults meeting the minimum LTPA recommendation increased over time (17·2% in 2000, 18·1% in 2005, and 22·8% in 2014), with the estimated prevalence change per year being 0·33% (95% CI 0·24-0·42; p<0·0001) for underweight people, 0·50% (0·47-0·53; p<0·0001) for normal-weight people, 0·37% (0·34-0·40; p<0·0001) for overweight people, and 0·06% (0·00-0·13; p=0·044) for obese people. We noted deteriorations over time in all measures of physical fitness in normal-weight adults (all p<0·0001), apart from resting heart rate (p=0·69). Despite increased participation in LTPA, we noted increases in overweight or obesity and a decrease in physical fitness in Chinese adults. Continued nationwide interventions are needed to promote physical activity and other healthy lifestyle behaviours in China.

Decreased health-related physical fitness in adults with ankylosing spondylitis: a cross-sectional controlled study

Objectives(1) Assess the health-related physical fitness of adults with ankylosing spondylitis (AS) and compare these to the general population, and (2) examine the relationships between physical fitness and condition-specific outcomes. DesignCross-sectional, controlled study. SettingExercise research laboratory. ParticipantsThirty-nine adults with AS (32 men, 7 women) and 39 age- and gender-matched controls. InterventionComprehensive physical fitness assessment, and completion of questionnaires assessing disease activity, physical function and quality-of-life. Main outcome measuresBody composition was assessed by bio-impedance analysis. Flexibility was measured with the Bath AS Metrology Index (BASMI). Cardiorespiratory fitness was assessed by submaximal treadmill test with breath-by-breath gas analysis and heart rate monitoring. Muscular strength and endurance were measured by isokinetic dynamometry of concentric knee flexion/extension. ResultsThe AS group demonstrated significantly lower cardiorespiratory fitness [mean difference −1.3mLmin−1kg−1 (95% CI −1.1 to −1.4)], flexibility [0.4 BASMI units (0.2 to 0.7)], muscular strength [−31.6 peak torque per body weight dominant knee extension (−56.1 to −7.1)], and increased body fat [0.4% (0.0 to 1.2)] compared to population controls (p<.05). There were significant associations between each fitness component and physical function (p<.05). Higher aerobic capacity was significantly associated with improved quality-of-life. Fitness was not significantly associated with disease activity. ConclusionAdults with AS have significantly reduced health-related physical fitness compared to population controls. Decreased body fat, and higher aerobic capacity, muscular fitness and flexibility are significantly associated with improved function. These findings have implications for clinicians assessing adults with AS, and for targeted-exercise prescription in this cohort.

Traveling by Private Motorized Vehicle and Physical Fitness in Taiwanese Adults.

Although the time spent sitting in motorized vehicles has been determined to be adversely associated with cardiometabolic health, its association with other health indicators remains unclear. This study examined associations between traveling by private motorized vehicle and 4 indicators of physical fitness in adults. Data from 52,114 Taiwanese adults aged 20 to 65years who participated in the 2013 National Adults Fitness Survey were used. The examined variables were height, body mass, and performance in modified sit-and-reach (flexibility), bent-leg sit-up (abdominal muscular strength and endurance), and a 3-min step test (cardiorespiratory endurance). Participants were asked on how many days they had used a private car or motorcycle for traveling from place to place and categorized as non-, occasional, and daily private motorized vehicle travelers. Logistic and linear regression models were used to examine associations between the categories of using private motorized vehicles to travel and physical fitness performance. After an adjustment for potential demographic and behavioral confounders, daily traveling by private motorized vehicle was associated with a higher probability of overweight (odds ratio = 1.18), lower performance of abdominal muscular strength and endurance (-0.37 times/min), and lower cardiorespiratory fitness (-0.60 physical fitness index) than was traveling that did not involve private motorized vehicles. The results suggest that in addition to unfavorable cardiorespiratory fitness and a risk of overweight, daily traveling by private motorized vehicle is associated with poor performance in abdominal muscular strength and endurance.

The Effects of A Combined Exercise, Healthy Diet, and Dental Hygiene Program on Body Composition, Physical Condition, Eating Habits, and Dental Care for Shelter Home Residents with Intellectual Disabilities

Introduction It has been documented that the physical fitness of adults with intellectual disabilities is less optimal than that of people without intellectual disabilities [1]. The prevalence of physical inactivity, poor diets, and obesity among people with intellectual disabilities is high [2].This may be attributed to their sedentary lifestyle, and associated with their health and mental condition. Temple and Walkley have reported that a low motivation to participate in physical activities, inadequate social support, unclear policies, and a lack of financial support are major factors inhibiting engagement in physical activities by people with intellectual disabilities [3]. Therefore, over time, their level of physical fitness and capacity to exercise will decrease. As a consequence, obesity rates will rise among this population, with resulting increases in the risk of developing diabetes, hypertension, cardiovascular disease, stroke, and other chronic diseases. Background: Physical inactivity, poor diet habit, and poor dental hygiene are big concerns among people with intellectual disabilities that cause a rise in obesity rates with increases in the risk of chronic diseases as well as emotional problems. A healthy diet and regular physical activity can prevent chronic diseases. Proper oral hygiene may improve a person’s health and quality of life. Yet, the effects of physical activity, healthy diet and oral care programs on people with intellectual disabilities who live in shelter homes are lack. The present study investigated the influence of a program integrating physical activity, a healthy diet, and dental hygiene on the physical functions, body composition, exercise and dietary habits, and oral care of a group of adults with intellectual disabilities living in a shelter home.

J Nutr Health Sci 1(3): 303. doi: 10.15744/2393-9060.1.303 Methods: Residents living in a shelter home (27 males and 24 females) participated in a 10-month integrated program consisted of a series of physical activity, healthy diets, and dental hygiene regime delivered by nurse and physiotherapist. Body composition, physical functions, changes in exercise and eating habits and dental hygiene were measured before and after the program. Results: After the program the participants showed a trend of improvement on physical functions on the Timed Up and Go test, Sit to Stand, single leg standing and Berg Balance Scale. Moreover, they tended to exercise for a longer duration and performed more than one type of exercise. The skills on brushing teeth were significantly improved and more participants acquired correct dental knowledge. However, no significant improvements on the body composition and eating habit. Conclusion: The present program integrating physical exercise, a healthy diet, and dental hygiene led some clinical improvement in physical function and exercise habit after the program for people with intellectual disabilities living in a shelter home. Moreover, improvements were seen in their skill in brushing their teeth and in their dental knowledge. No significant change was seen in their body composition and eating habits.
