The purpose of this study was to determine if the regression formula developed for the 20-m shuttle run test (20 MST) for children and adolescents with mild mental retardation (MR), used to predict cardiovascular fitness (V̇O2peak), is valid for adolescents with Down syndrome (DS). Twenty-six adolescents (mean age = 15.3 ± 2.7 yr) with DS (15 males, 11 females) completed a maximal treadmill protocol (measured V̇O2peak) and a 20 MST (predicted V̇O2peak). There was a significant difference (p < .01) between the means of the measured (25.5 ± 5.2 ml·kg-1-·min-1) and the predicted (33.5 ± 3.9 ml·kg-1·min-1) V̇O2peak, respectively. In addition, there was a low relationship between measured and predicted values (r = .54). The results of this study indicate that the regression formula developed for children and adolescents with MR to predict V̇O2peak was not valid in this sample of adolescents with DS.

The purpose of this study was to identify the most accurate predictor of VO2max from a variety of running tests. 32 young adult male undergraduates of (mean ± SE) age 20.14 ± 0.34 yr., height 179.4 ± 1.8 cm, weight 73.7±2.8 kg, and VO2max 57.89 ± 1.1 ml · kg−1 · min.−1 were randomly tested on four different predictive VO2max running tests to assess their actual VO2max, based on a continuous, progressive treadmill protocol and obtained via gas analysis. The four tests consisted of a treadmill jogging test, 1.5 mile run, Cooper's 12-min. run, and the 20-m progressive shuttle-run test. An analysis of variance applied to means indicated significance. Post hoc analysis between the means with correction by Scheffé showed significant difference between the predictive submaximal treadmill jogging test and the 12-min. run but no other difieren .es. The strength of the relationship between predictive tests and VO2max varied, wit1 the 12-min run having the highest correlation of .87, followed by the 1.5 mile rur .87, 20-m progressive shuttle run .82, and the treadmill jogging test .50. The 12-min. run had the highest correlation of all tests with VO2max in young men, with active to trained levels of fitness. The 1.5 mile and 20-m shuttle run also provided accurate predictions of VO2max and so should be used for an accurate prediction of young men's VO2max.

We cross validated the 20-m shuttle run test of aerobic capacity in children and adolescents with mild and moderate mental retardation (MR) using the population specific formula of Fernhall et al. (1998). Nine boys and 8 girls (age = 13.7 yr) completed a maximal treadmill protocol (measured V̇O2peak) and a 20-m shuttle run (predicted V̇O2peak). The measured peak oxygen consumption (V̇O2peak) was 39.4 ml kg-1 min-1. The relationship between measured and predicted V̇O2peak was r = .86 with an SEE of 6.2 ml kg-1 min-1. Multiple regression and Bland-Altman analyses showed that there was little bias, but the Bland-Altman analysis indicated highly variable limits of agreement (Bland & Altman 1986). Thus, the traditional approach (regression analysis) to concurrent validity revealed that the 20-m shuttle run is a valid indicator of V̇O2peak in these participants. The accuracy of prediction (Bland & Altman, 1986), however, was lower than expected in a population without MR.

Two regression equations were developed to predict cardiovascular fitness (CVF) based on the 20-m shuttle run test (20-MST) for nondisabled youth and for youth with mild mental retardation (MR). The purpose of this study was to compare the validity of both regression formulas to predict CVF in nondisabled, healthy youths (ages 8 to 15 yrs; 38 females and 13 males). Participants performed two modified Bruce protocol treadmill (TM) tests and two 20-MSTs on separate days. CVF (V̇O2peak, ml • kg−1 • min−1) was measured during the TM tests and computed for the 20-MST using both regression equations. Results indicate that test-retest correlations for the 20-MST (# of laps; r = 0.89) and TM test (V̇O2peak, ml • kg−1 • min−1; r = 0.86) were high. Predicted V̇O2peak values were moderately significant (nondisabled youth: r = 0.55, p < .01; youth with MR: r = 0.66, p < .01) when compared with TM V̇O2peak. Correlation between the two regression equations was significant (r = 0.78, p < .01).

The aim of this study was to investigate the effects of a school-based cardiovascular-fitness-training program in children with mental retardation (MR). Thirty boys (8−15 years old) with mild to moderate mental retardation were randomly divided into 2 groups—experimental (EX) and control (CN). The EX group underwent 10 weeks of training 3 times/week for a duration of 1 hr/session at 60-80% peak heart rate. At Week 10, significant increases in 20-m shuttle-run-test (20-MST) laps were observed for the EX group. No improvements were found in percent body fat. No changes were observed for the CN. The school-based training program might prove useful in improving the cardiovascular fitness of children with MR.

Spatial Limitation

Background and objective: The disadvantage of the traditional 20-m multistage shuttle run test (MST) is that it requires a long space for measurements and does not include various age groups to develop the test. Therefore, we developed a new MST to improve the spatial limitation by reducing the measurement to a 10-m distance and to resolve the bias via uniform distributions of gender and age. Material and methods: Study subjects included 120 healthy adults (60 males and 60 females) aged 20 to 50 years. All subjects performed a graded maximal exercise test (GXT) and a 10-m MST at five-day intervals. We developed a regression model using 70% of the subject's data and performed a cross-validation test using 30% of the data. Results: The male regression model's coefficient of determination (R2) was 58.8%, and the standard error of estimation (SEE) was 4.17 mL/kg/min. The female regression model's R2 was 69.2%, and the SEE was 3.39 mL/kg/min. The 10-m MST showed a high correlation with GXT on the VO2max (males: 0.816; females: 0.821). In the cross-validation test for the developed regression models, the male's SEE was 4.38 mL/kg/min, and the female's SEE was 4.56 mL/kg/min. Conclusion: Thus, the 10-m MST is an accurate and valid method for estimating the VO2max. Therefore, the 10-m MST developed by us can be used when the existing 20-m MST cannot be used due to spatial limitations and can be applied to both men and women in their 20s and 50s.

This study examined whether 20-m shuttle-run performance, sex, body mass index (BMI), age, height, and weight are associated with peak oxygen uptake (VO2peak) in youth with Down syndrome (DS; n = 53; 25 women, age 8–20 years) and whether these variables can be used to develop an equation to predict VO2peak. BMI, 20-m shuttle-run performance, and sex were significantly associated with VO2peak in youth with DS, whereas age, height, and weight were not. A regression model included only shuttle-run performance as a significant predictor of VO2peak; however, the developed prediction equation had low individual predictability. Therefore, 20-m shuttle-run performance alone does not provide valid prediction of VO2peak in youth with DS. Sex, BMI, age, height, and weight do not improve the prediction of VO2peak.

ABSTRACT Objective: To systematically review the literature as for the level of evidence of predictive equations of VO2peak through the 20-meter shuttle run test (20m-SRT) in children and adolescents. Data sources: Searches were conducted independently by two researchers, according to the procedures adopted by PRISMA, in the electronic databases MEDLINE via PubMed, ScienceDirect, Web of Science, LILACS and SciELO, for articles published until September 2017 in English and Portuguese. The inclusion criteria were: original studies, abstract available, using predictive equations of VO2peak through 20m-SRT, conducted with adolescents and/or children, non-athletes, and mentioning correlation analysis between predicted and measured VO2peak. The level of evidence of equations was based on the risk of bias of the studies using the following criteria: sample number, sample characteristics, and statistical analysis. Data synthesis: Eighteen studies were selected, in which fifteen equations were found and analyzed. The studies had been conducted with samples composed of subjects of both sexes, aged 8 to 19 years. Equations of Léger and Matsuzaka had their level of evidence classified as high, and estimation ranged between r=0.54-0.90 and r=0.65-0.90. Equations by Ruiz, Barnett and Matsuzaka had their level of evidence classified as moderate, and estimation ranged between r=0.75-0.96, r=0.66-0.84 and r=0.66-0.89, respectively. Conclusions: Matsuzaka’s equation presented satisfactory parameters for estimates of VO2peak in children and adolescents. Although not explored in equations, body adiposity and pubertal stage are significantly associated with cardiorespiratory fitness in children and adolescents.

Sports, the most ancient human endeavour, known through ages since the time of Hercules, relates to various form of recreational activities like hunting, shooting, sailing,, outdoor games, athletics, swimming etc .Every society tries to include certain values in younger generation through the medium of sports. Ancient society want to encourage valour, dignity and loyalty to the group. Likewise modern society emphasizes specialization, professionalization and commercialization in the realm of sports also. In the present day scenario “Sports For all” has become a popular slogan all over world. Games and sports are is the specialised field. It requires a specific, scientific, and systematic type of training to increase optimum performance of the player. Each game requires different and specific type of physical fitness, components and training method to develop that components there are five physical fitness components and inter related to each other directly and indirectly each components has its own importance in different  games and sports. Volleyball and Handball required flexibility and agility which influence the performance of the player and game. That is why the purpose of the study was to compare the flexibility and agility between the state and national level players of volleyball and handball of district Poonch( jammu and Kashmir) state. To collect data for this study, total 30 (No 30) subject were selected out of which fifteen(15) from Handball and fifteen from Volleyball discipline in District Poonch of J&K State. The age of the subject were ranged from 15 to 20 years according to the school and college records. Flexibility and agility ability  were selected as dependent variables for the study. Sit and reach test was used to measured flexibility and 10*4 shuttle run test was used to measured agility of the players. These tests were administered after proper ground marking, proper demonstration and  proper warming up of the players. The collected data  were statistically analyzed for significant difference by using independent  test. The level of significance was set at 0.05.

The aim of this research is to confirm differences in the anthropometric characteristics and motor abilities of schoolchildren aged 9 and 10 compared by sex and age. The sample comprised 341 schoolchildren, divided into two subgroups of third (172) and fourth (169) graders. The research is of a transversal character and includes the measurement of anthropometric characteristics and motor abilities by applying the Eurofit fitness testing battery. The results show a significant difference based on sex in terms of body mass (t = 2.148), and as for motor abilities, there is a difference in the Shuttle run test (t = -3.709). A statistically significant difference considering the age of the tested population was observed in height (t = -10.327) and body mass (Z = -5,991), while in terms of motor abilities there was a statistically significant difference in the values of all the tests: Hand tapping (t = 4.735), the Standing long jump (Z = -3,575), Shuttle run (t = 12,248), the Flexed arm hang (Z = -2,167), Sit and reach (Z = -2,406), Sit-ups in 30 seconds (t = -9069). The research shows a higher statistically significant difference observed in body composition, but also in the motor area of the studied group in terms of age, and in relation to the statistically significant difference that was revealed by gender.
