Aerobic Fitness Status and Out-of-School Lifestyle of Rural Children in America and Russia

Peter Hastie, Oleg Sinelnikov, and Danielle Wadsworth


This study compares the aerobic fitness status of a sample of rural American and Russian children, and examines these findings in light of their out of school physical activity participation.


Ten and eleven year old (N = 415) children from both countries completed a 15 m Progressive Aerobic Cardiovascular Endurance Run (PACER) fitness test, and following the test, the children scoring beyond the upper limit of the healthy fitness zone were interviewed with regard to their out-of-school participation in physical activity.


The Russian students achieved significantly higher scores than American students (P < .001), and males scored higher than females for both countries (P < .001). After examining the profiles of the students 3 apparent themes begin to emerge: Russian students walk to and from school; the students in both settings who achieve a superior fitness level participate in after school physical activity; after school activities for the American students appear to be more recreational orientated than the Russian students, who participate in structured training in sports clubs.


For the students in this study, it appears that participating in after school activity may have contributed to achieving high levels of aerobic fitness.

Association Between Aerobic Fitness and High Blood Pressure in Adolescents in Brazil: Evidence for Criterion-Referenced Cut-Points

Criterion-referenced cut-points for health-related fitness measures are lacking. This study aimed to determine the associations between aerobic fitness and high blood pressure levels (HBP) to determine the cut-points that best predict HBP among adolescents.


This cross-sectional school-based study with sample of 875 adolescents aged 14–19 years was conducted in southern Brazil. Aerobic fitness was assessed using the modified Canadian Aerobic Fitness Test (mCAFT). Systolic and diastolic blood pressure were measured by the oscillometric method with a digital sphygmomanometer. Analyses controlled for sociodemographic variables, physical activity, body mass and biological maturation.


Receiver Operating Characteristic (ROC) curves demonstrated that mCAFT measures could discriminate HBP in both sexes (female: AUC = 0.70; male: AUC = 0.63). The cut-points with the best discriminatory power for HBP were 32 mL·kg-1·min-1 for females and 40 mL·kg-1·min-1 for males. Females (OR = 8.4; 95% CI: 2.1, 33.7) and males (OR: 2.5; CI 95%: 1.2, 5.2) with low aerobic fitness levels were more likely to have HBP.


mCAFT measures are inversely associated with BP and cut-points from ROC analyses have good discriminatory power for HBP.

Aerobic Fitness: Measurement and Issues

Stephen H. Boutcher

The effects of aerobic fitness on psychological and behavioral variables are currently receiving increased attention. However, the results of past research in these areas are equivocal, mainly due to differences in the methods used to quantify aerobic fitness and the failure to address issues concerning adaptation responses to aerobic training. It is suggested that direct assessment of V02max and estimation of lactate threshold are currently the most suitable measures of aerobic power and adaptation responses to aerobic exercise. To better understand how aerobic fitness affects psychological variables, it is also necessary to consider genetic influences and level and mode of adaptation to aerobic training. It is suggested that there should be more focus on examining underlying mechanisms common to both aerobic fitness and the phenomenon of interest. This focus should integrate multiple adaptation patterns and physiological and psychological responses rather than measure solitary parameters.

Youth Aerobic Fitness

Neil Armstrong

Aerobic (or cardiorespiratory or cardiopulmonary) fitness reflects the integrated ability to deliver oxygen from the atmosphere to the skeletal muscles and to utilize it to generate energy to support muscle activity during exercise. Aerobic fitness is the most researched physiological variable in

The Dose-Response Relationship Between Training Load and Aerobic Fitness in Academy Rugby Union Players

Richard J. Taylor, Dajo Sanders, Tony Myers, Grant Abt, Celia A. Taylor, and Ibrahim Akubat

Rugby union is a high-impact collision sport played over 80 minutes. 1 Games are typically aerobic in nature, interspersed with frequent bouts of high-speed accelerations combined with high-impact collisions from tackles, scrums, rucks, and mauls. 2 Aerobic fitness has previously been shown to be
