Trained Runners

The purpose of this study was to compare physical fitness levels of trained runners with mild mental retardation (MMR) (7 males and 2 females, age = 28.7 ± 7.4 years, weight = 67.0 ± 11.7 kg) and those without (7 males and 2 females, age = 29.1 ± 7.5, weight = 68.7 ± 8.8 kg). Paired t tests revealed no differences between runners with and without MMR on measures of V̇O2peak (56.3 ± 9.1 vs. 57.7 ± 4.1 ml · kg-1 · min-1), percent body fat (16.6 ± 8.4 vs. 16.6 ± 3.1), and lower back/hamstring flexibility (33.1 ± 10.9 vs. 28.6 ± 10.1 cm). Knee flexion (KF) and extension (KE) strength were significantly greater in runners without MMR compared to those with MMR (KF peak torque = 65.7 ±7.9 vs. 48.7 ± 15.7 ft/lb; KE peak torque = 138.5 ± 17.7 vs. 104.4 ± 29.9 ft/lb). It was concluded that trained runners with MMR can achieve high levels of physical fitness comparable to individuals without MMR.

Level Of Significance

In order to compare their physical fitness, the UNIQUE Physical Fitness Test was administered to 203 retarded and nonretarded subjects with cerebral palsy from both segregated and integrated settings throughout the United States. The test was administered to subjects between the ages of 10 and 17 by professional persons prepared as field testers. Subjects were free from multiple handicapping conditions other than mild mental retardation and cerebral palsy. Regardless of intellectual classification, older subjects significantly exceeded the performance of younger subjects on dominant grip strength. Regardless of intellectual classification, older subjects significantly exceeded the scores of younger subjects on the softball throw and flexed arm hang. No significant differences between retarded and nonretarded subjects at the .01 level of significance were found on any of the test items on the UNIQUE test. The factor structures of both retarded and nonretarded groups were identical with regard to the items that loaded on specific physical fitness factors.

PURPOSE: The purpose of this study was to investigate the relationship of smartphone use time, sitting time, and fitness level in university students.METHODS: The participants of this study were 237 healthy university students (157 males and 80 females) enrolled from 2017 to 2018. The smartphone use time was divided into three groups: 0-4, ≥4-10, and ≥10 hours, as was the sitting time: 0-4, 4-7, and ≥7 hours. Binary logistic regression was used to calculate the odd ratio (OR) and 95% confidence interval (CI) of the smartphone use time and sitting time for having low levels of fitness.RESULTS: There were linear decreases in physical fitness levels across incremental smartphone use time and sitting time. Compared to the smartphone use time for 0-4 hours (reference), smartphone use time for the ≥4-10 hours (OR=2.498; 95% CI=1.007-6.197; <i>p</i>=.048) or the 10≥group (OR=3.516; 95% CI=1.228-10.064; <i>p</i>=.019) had significantly higher ORs of having lower fitness even after adjustments for age, sex, physical activity and percent body fat. Likewise, logistic regression analyses showed that those who had sitting time for ≥7 hours (OR=3.135; 95% CI=1.155-8.512; <i>p</i>=.025) had significantly higher ORs of having lower fitness even after adjustments for age, sex, physical activity, and percent body fat, as compared with those who had sitting time for 0-<4 hours.CONCLUSIONS: The current finding suggest that the smartphone using time and sitting time were associated with having the risk of lower level of physical fitness in university students.

Komposisi tubuh yang tidak optimal dapat menurunkan kesegaran jasmani atlet sehingga dapat terjadi penurunan performa ketika bertanding. Tujuan dari penelitian ini adalah mengetahui hubungan persen lemak tubuh, persen massa otot, dan somatotype dengan kesegaran jasmani pada atlet hockey. Desain penelitian yaitu cross-sectional dengan jumlah subjek 35 atlet di Pelatihan Hockey Universitas Negeri Semarang dan Universitas Negeri Yogyakarta yang dipilih dengan purposive sampling. Data persen lemak tubuh dan persen massa otot diukur menggunakan bioelectrical impedence analysis (BIA). Data somatotype menggunakan metode antropometri Heath-Carter dan data kesegaran jasmani berupa nilai VO2max diambil menggunakan metode Balke. Analisis data menggunakan uji Pearson, Rank Spearman dan uji regresi linier. Sebagian besar atlet hockey (54,3%) memiliki nilai VO2max dengan kategori baik. Nilai persen lemak tubuh terendah 6,8% dan nilai tertinggi 35%. Nilai persen massa otot terendah 23,9% dan nilai tertinggi 40,9%. Nilai rata-rata dari nilai endomorph, mesomorph, dan ectomorph adalah (-0,04)±0,3; 4,2±0,9; dan 2,3±1,2. Ada hubungan yang signifikan antara persen lemak tubuh (p<0,001), persen massa otot (p<0,001), nilai endomorph (p<0,001), dan nilai ectomorph (p=0,016) dengan nilai VO2max. Variabel yang paling berkaitan dengan nilai VO2max adalah persen lemak (p<0,001). Correlation of body composition with physical fitness of hockey athletes AbstractSuboptimal body composition could reduce the physical fitness and performance of athletes. This study analyzed the relationship of percent body fat, percent muscle mass and somatotype on physical fitness in hockey athletes. This study was a cross-sectional study with 35 athletes in Pelatihan Hockey Universitas Negeri Semarang and Universitas Negeri Yogyakarta which selected by purposive sampling. Percent body fat and percent muscle mass were measured using bioelectrical impedance analysis (BIA). Somatotype measurement used the anthropometric Heath-Carter method and physical fitness (VO2max) measurement by the Balke method. Data were analyzed using the Pearson test, Rank-Spearman test, and Linear Regression test. Most hockey athletes (54.3%) had good VO2max value. The lowest percentage of body fat was 6.8%. The highest percentage of muscle mass was 40.9%. The average value of the endomorph, mesomorph, and ectomorph values were (-0.04) ± 0.3; 4.2 ± 0,9; and 2.3 ± 1.2.  There were a significant relationship between percent body fat (p <0.001), percent muscle mass (p <0.001), endomorph value (p <0.001), and ectomorph value (p = 0.016) with VO2max value. Percent of body fat was the most related variable to VO2max (p<0.001).

Objectives : The aim of this study was to examine the effects of 8 weeks beta-alanine (BA) supplementation with resistance training on some components of physical fitness and body composition in young males. Methods : Twenty healthy young men volunteered to participate for the study and divided into two groups and performed 8-week resistance training while supplementing with either BA or placebo (4.8 g per day). The subjects were evaluated for 1 repetition maximum (1RM) bench press and leg press, vertical jump (VJ), anaerobic power (RAST) prior to and after training intervention. In addition, body composition variables such as percent body fat, and BMI were assessed per and post training period. Results : Both the groups showed significant increases in 1RM bench press and leg press, VJ, and anaerobic power (RAST), and also the BA supplementation group showed greater gains compared with the placebo. In addition, percent body fat decreased significantly in BA and placebo groups, while no statistically significant changes were seen in BMI for the BA supplementation group and placebo group. Conclusions : The results indicated that resistance training improved physical performance and BA supplementation induced greater gains and therefore it could be recommend to coaches and athletes who use this supplementation to greater gains in physical fitness variables.

Background: Physical activity performed at moderate intensity is associated with reduced risk of mortality, cardiovascular disease, hypertension, and some types of cancers. However, vigorous physical activity during participation in college athletics may increase the risk of injury, which might limit future physical activity levels. Purpose: To evaluate differences in current physical fitness levels between former Division I athletes and noncollegiate athletes. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: The sample was recruited from a large midwestern university alumni database and consisted of 2 cohorts: (1) former Division I athletes (n = 100; mean age, 53.1 ± 7.4 years) and (2) nonathletes who were active in college (n = 100; age, 51.4 ± 7.3 years). Individuals answered a demographics questionnaire and completed a physical fitness assessment consisting of 7 measures: percent body fat, 1-mile walk, sit-to-stand test, push-up, half sit-up test, sit and reach test, and back scratch test. Results: Performance was significantly worse for former Division I athletes compared with nonathletes for percent body fat (mean difference, 7.58%; F(1, 198) = 59.91; P < 0.01), mile time (mean difference, 2.42 minutes; F(1, 198) = 1.74; P = 0.03), sit-to-stand test (mean difference, 4.3 repetitions; F(1, 198) = 6.59; P = 0.01), and push-up test (mean difference, 8.9 repetitions; F(1, 198) = 7.35; P = 0.01). Conclusion: Former Division I athletes may be limited because of previous injury, inhibiting their ability to stay active later in life. Clinical Relevance: It is imperative that clinicians, coaches, and strength and conditioning specialists understand the possible future repercussions from competing at the Division I level.

The present study evaluated the effects of a reinforcement based aerobic and resistance exercise program on three obese men with mental retardation and below average fitness levels. A multiple-baseline-across-subjects design was employed to evaluate treatment effectiveness and retention of treatment effects on five dependent measures: body weight, percent body fat (body composition), oxygen consumption (predicted max V̇O2 in ml/kg/min), composite isometric strength (in kg of force), and work productivity (pieces of work completed). Subjects improved during treatment from their baseline scores on cardiovascular fitness, strength, and work productivity measurements (p<.05); however, retention of gains made during treatment were inconsistent and the data that indicated subjects’ scores were regressing back toward baseline measurements. There were no significant differences for body weight and percent body fat measurements for treatment and retention phases (p>.05). Results indicated that adults with mental retardation respond to a progressive exercise program in much the same manner as their nonretarded peers and that such an exercise program can facilitate job performance.

Little data exist on the comparison of blood lipids and percent body fat between Down Syndrome and non-DS adults with mental retardation (MR). The following study was undertaken to determine if there were physiological and biochemical differences between these two groups. Subjects included 294 non-DS adults with MR (162 males and 132 females) and 31 adults with Down Syndrome (21 males and 10 females). Level of mental retardation was similar for both groups (males/females, Down vs. non-DS). A two-factor ANOVA with a regression approach was used to analyze the data. Results of the study found that there were no significant differences between the Down Syndrome and non-DS subjects on total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, or percent body fat. The present study suggests that the composition of lipoproteins and storage of body fat are similar in Down Syndrome and non-DS adults with mental retardation, and that the risk for developing coronary heart disease appears to be the same for both groups.
