The aims were to develop and validate a VO2peak prediction equation from a treadmill running test in active male adolescents. Eighty-eight athletes (12–18 yrs.) performed a maximal exercise test on a treadmill to assess the actual VO2peak and a 20m Shuttle-Run-Test (20mST). A step-wise linear regression analysis was used and the following equation for estimation of VO2peak (mL·kg−1·min−1) = 35.477 + 1.832 × duration in min - 0.010 × duration × body mass in kg was developed. The cross-validation statistics were: R = .54, CE = 0.1 mL·kg−1·min−1, SEE = 2.5 mL·kg−1·min−1 (4.6%), and TE = 2.6 mL·kg−1·min−1 (4.9%). The cross-validation values (CE, SEE, and TE) were lower compared with those of previously published equations in adolescents that estimated VO2peak using anthropometric data, performance in 20mST, and energy cost at submaximal speeds.

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.

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.

The aim of the study was to analyze if there is a connection between some anthropometric measrements and a test for assessing aerobic ability in footballers of different age categories. 65 players were subjected to these measurements, of which 25 players aged 13-14 years (pioneers); 20 players aged 15-16 years (cadets) and 20 players aged 17-18 years (juniors). By using standard anthropometric instruments, body height, body weight, median volume of the chest and aerobic endurance were measured using a 20m “shuttle run” test. Using linear regression analysis, it was found that there is no statistically significant effect of anthropometric variables on a variable (20m “shuttle run”) of all three age players. In these ages, obviously some other characteristics have more influence on the manifestation of aerobic ability. The results of the research can be used by experts in the field of sports in further planning and organizing training contents

AbstractThis study compared maximum oxygen consumption (VO2max) on a 20-meter multistage shuttle run test (20-Srt) with a cardiopulmonary exercise test (CPET) to determine a VO2max prediction equation for a 20-Srt in children aged 6–10 years. Eighty healthy children performed the CPET on a treadmill, while the 20-Srt took place on a sports court. Heart rate (HR) was measured and the expired gases were continuously measured breath-by-breath using a portable gas analyzer. The VO2max was lower (p<0.05) in CPET than 20-Srt for all, female, and male participants, respectively (46.3±7.9 vs. 48.7±4.6; 42.7±7.8 vs. 46.7±4.8; 49.3±6.8 vs. 50.4±3.9, mL·kg-1·min-1). The standard error estimates were between 3.0 and 3.6 and considered as not clinically relevant if less than 5 mL·kg-1·min-1. The intraclass correlation coefficient between the VO2 in CPET and in 20-Srt was 0.74 (CI95% 0.55–0.84) and considered moderately reliable. The linear multiple regression excluded sex, body mass index and fat-free mass and retained the maximum speed and age in the predictive equation. The 20-Srt estimates the VO2max with moderate reliability and the predictive equation was VO2maxpred=4.302+(maximum speed*5.613)–(age*1.523) for children aged 6–10 years.

Objectives:To frame individualized gender – specific prediction equations for shuttle run distance using 20 metre shuttle run test in healthy, Indian children aged between 7 to 19 years and to correlate shuttle run distance with age, height, weight & body mass index. Methods: 494 subjects between the age group of 7 to 19 years were recruited in this study. Demographic details like age, gender, height, weight and body mass index were noted. 20 metre shuttle run test was performed and shuttle run distance was calculated for all participants. Results: Shuttle run distance significantly correlated with age (r =0.303), height (r =0.357), weight (r =0.294), and body mass index (r =0.126). The gender specific reference equation generated forboys is -367.724 + (27.225 x Age) + (487.457 x Height) – (3.213 x Weight) and for girls is 153.689 +(10.306 x Age) +(118.113 x Height) – (1.421 x Weight). Conclusion: The established prediction equation can be used as a reference to evaluate exercise capacity for children and adolescents and to improve the applicability of the 20 metre shuttle run test in clinical practice

Three papers, which between them contribute to the current debate on the assessment and interpretation of pediatric aerobic fitness, were selected for commentary. The first paper (Children. 2017; 4:6; doi:10.3390/children4010006) highlights the merits of clinical exercise testing and advocates the advancement of pediatric exercise testing through a rationale founded on demonstrated prognostic value of data obtained. It notes the lack of well-accepted definitions of exercise outcome variables in children and promotes the case for data harmonization across laboratories. The second paper (J Appl Physiol. 2017; 122: 997–1002) argues persuasively that the acceptance of peak oxygen uptake (peak ) at the termination of an exercise test to voluntary exhaustion as a surrogate for a “true” maximal value (ie, ) is no longer tolerable. The authors present a compelling case for the adoption of a follow-up verification test to unambiguously validate the achievement of . The third paper (Br J Sports Med. 2017; 1–10, doi:10.1136/bjsports-2017-097982) compiles large, previously published datasets to provide a review of temporal trends in 20-m shuttle run test scores. The authors assert that temporal trends in 20-m shuttle run test performance provide meaningful insight into trends in population health. The commentary stresses the importance of scientific rigor in pediatric exercise testing, emphasizes the use of precise definitions when describing health-related variables, and cautions against the misuse of exercise outcome measures in recommendations relating to or impacting on young people’s health and well-being.

ObjectivesThe 20 m shuttle run test (20mSRT) is used to estimate cardiorespiratory fitness (CRF) through the prediction of peak oxygen uptake (V˙O2), but its validity as a measure of CRF during childhood and adolescence is questionable. This study examined the validity of the 20mSRT to predict peak V˙O2 .MethodsPeak V˙O2 was measured during treadmill running. Log-linear regression was used to correct peak V˙O2 for body mass and sum of skinfolds plus age. Boys completed the 20mSRT under standardised conditions. Maximum speed (km/h) was used with age to predict peak V˙O2 using the equation developed by Léger et al. Validity was examined from linear regression methods and limits of agreement (LoA). Relationships between 20mSRT performance and allometrically adjusted peak V˙O2, and predicted per cent fat were examined.ResultsThe sample comprised 76 boys aged 11–14 years. Predicted and measured mass-related peak V˙O2 (mL/kg/min) shared common variance of 32%. LoA revealed that measured peak V˙O2 ranged from 15% below to 25% above predicted peak V˙O2 . There were no significant relationships (p>0.05) between predicted peak V˙O2 and measured peak V˙O2 adjusted for mass, age and skinfold thicknesses. Adjusted for body mass and age, peak V˙O2 was not significantly related (p>0.05) to 20mSRT final speed but a weak, statistically significant (r=0.24, p<0.05) relationship was found with peak V˙O2 adjusted for mass and fatness. Predicted per cent fat was negatively correlated with 20mSRT speed (r=−0.61, p<0.001).ConclusionsThe 20mSRT reflects fatness rather than CRF and has poor validity grounded in its flawed estimation and interpretation of peak V˙O2 in mL/kg/min.
