“…It is known that ergospirometry is the gold standard for evaluation of cardiorespiratory fitness, especially for scientific studies or evaluations which require greater accuracy (8,11,19,20) . In order to indirectly measure the O 2max, measurement instruments such as cycle ergometers and treadmills, wooden benches as well as application of field tests (run or gait) have been used (21) .…”

The aim of this study was to compare the values of O 2max directly determined by an ergospirometry system, with values indirectly predicted by the ErgoPC system during maximal exercise test underwent by female runners. Twenty trained female runners participated in the study ( 42.7 ± 6.4 years-old, height 1.64 ± 0.04m, body mass 58.3 ± 5.8kg, body mass index (BMI) 21.7 ± 1.9kg/m 2 and body fat percentage 22.3 ± 3.5. The subjects were evaluated for body composition and underwent a progressive exercise test on treadmill (Inbrasport, Porto Alegre, RS, Brazil) to measure the aerobic fitness ( O 2max ). The initial speed was 7km/h with increments of 1km/h every three minutes and constant inclination of 1% was kept throughout the test. The participants were encouraged to remain in the test as long as possible until voluntary exhaustion. The gas analyzer VO2000 Inbrasport Spirometer, Porto Alegre, Brazil was used for the direct measurement of O 2max , while for the indirect measurement of O 2max the ErgoPC program with the prediction formula from Foster (1996) was used. Statistical analysis was performed by Student's t test for the comparison of the values of O 2max obtained in the direct and indirect test, and Pearson's correlation was applied to correlate these two variables. Direct measurement of O 2max showed a value of 51.8 ± 6.8ml/kg/min and indirect one of 42.8 ± 3.7ml/kg/min. The comparison between both results was significantly different. The correlation between the values of O 2max was r = 0.67. Thus, the results show that the obtained O 2max by an indirect way underestimates the value of the direct measurement.

“…Na avaliação das capacidades físicas, seja em laboratório ou em testes de campo, indica-se o uso de ergômetros e/ou testes que mais se aproximem das ações e gestos esportivos utilizados na modalidade praticada 22 . Porém, como não existe um protocolo de cargas progressivas para a aula no mini-trampolim, e de acordo com outra pesquisa na área com aulas de ginástica de academia 17 , o protocolo utilizado para avaliação cardiorrespiratória foi o TI em esteira ergométrica.…”

O Power Jump (PJ) caracteriza-se como uma aula segura, de fácil execução, com ações intermitentes retardando a fadiga. Contudo, são escassos os estudos específi cos sobre o assunto. O objetivo deste estudo foi determinar a intensidade da aula de PJ por meio da freqüência cardíaca (FC). Participaram do estudo 11 mulheres praticantes da modalidade (21,7±1,9 anos; 59,3±4,8kg; 162,6±5,6cm; 22,6±3,2 %G aBstraCtA Power Jump (PJ) session is considered to be a safe and easy class that also involves intermittent exercises that prolong the time to exhaustion. However, there is not enough information about this subject in the literature. The purpose of this study was to determine the intensity of a PJ session by means of heart rate (HR) monitoring. Eleven physically active females participated in the study (age: 21.7 ± 1.9 years; body mass: 59.3 ± 4.8 kg; height: 162.6 ± 5.6 cm; percentage body fat: 22.6 ± 3.2 %). Participants were asked to perform an incremental test (IT), in order to obtain values for oxygen uptake (VO 2 ), maximal heart rate (HRmax), heart rate defl ection point (HRDP) and energy expenditure (EE). The HR of the subjects was monitored during a special type of Power Jump session called "mix nine" on two different occasions. According to the HRDP values, physiological domains could be divided into three exercise intensity classes: moderate, heavy and severe. Descriptive statistics were adopted (mean ± SD). Student's t test was used to compare HR and EE between PJ1 and PJ2. For comparisons between domains, two-way ANOVA and the Scheffé test were used. The level of signifi cance was set at p<0.05. Mean HRmax obtained during the IT was 195±10bpm. The velocities, HR and %HRmax corresponding to HRDP and 80% of HRDP were 10.1±0.95km.h-1, 178±7bpm and 91.7±4.0%; and 8.1±0.76km.h-1, 143±5bpm and 73.4±3.2%, respectively. Values for HRmean and EE were signifi cantly different when PJ1 (161±11bpm, 386±58.2kcal) and PJ2 (156±10bpm, 355.1±53.8kcal) were compared. The times spent in each exercise intensity domain were: heavy 51±14.5%; severe 27±19.7% and moderate 23±8.7%. These results show that the subjects spent most of the time in the heavy exercise domain which, in turn, appears to be the most indicated for improving aerobic capacity.

“…These results were also transformed into VO 2peak absolute (VO 2pe-ak abs) (L.min . This test has shown good validity (r=0.71) and reproducibility (r=0.89) in children and adolescents 18 and has also been used in test batteries from other countries such as FITNESSGRAM and EUROFIT 19 . Socioeconomic status was defined using the questionnaire and classification of the Brazilian Association of Research Companies (ABEP) 20 , which estimates the purchasing power of families and classifies it from high to low into classes A, B, C, D and E. The students were assigned to high (A+B), medium (C+D), and low socioeconomic classes (E).…”

-Aerobic fitness is an important health-related fitness component. The objective of this study was to analyze the influence of age, growth, body composition, sexual maturation and socioeconomic status on the aerobic fitness of female school children attending public schools in Cascavel, Paraná, Brazil. A cross-sectional epidemiological study was conducted in 2006 on 1,317 school children aged 8 to 17 years. Body mass, height and triceps and medial calf skinfold thickness were measured and relative body fat (%BF) was calculated. Sexual maturation was self-assessed using a breast development scale (M1 to M5). The questionnaire proposed by the Brazilian Association of Research Companies was used to assess socioeconomic status. Aerobic fitness was estimated by the 20-m shuttle run test. The results were analyzed using two-way ANOVA, Tukey post hoc test, Spearman and Pearson correlation coefficients, and multiple linear regression with 95% confidence intervals. Three variables (age, %BF and socioeconomic status) showed an interaction (p<0.05) in the prediction of VO 2peak rel (R 2 =0.73). All independent variables (body mass, height, age, %BF, socioeconomic status, and sexual maturation) were significant predictors (p<0.05) of VO 2pico abs (R 2 =0.88). In conclusion, chronological age and sexual maturation were the best predictors of VO 2peak abs (positive) and VO 2peak rel (negative). Key words: Adiposity; Physical fitness; Puberty, Social class; Students. Resumo -A aptidão aeróbia é considerada um dos mais importantes componentes da aptidão física relacionada à saúde. O objetivo deste estudo foi analisar a influência da idade, das variáveis de crescimento, composição corporal, maturação sexual e do nível econômico (NE) sobre aptidão aeróbia em escolares do sexo feminino de escolas públicas da cidade de
