Abstract
Aims A cardiopulmonary exercise (CPX) test is considered the gold standard in evaluating maximal oxygen uptake. This study aimed to evaluate the predictive validity of equations provided by Burr et al., Ross et al., Adedoyin et al., and Cahalin et al. in predicting peak VO2 from 6 min walk test (6MWT) distance in patients with heart failure (HF). Methods and Results New York Heart Association Class I–III HF patients performed a maximal effort CPX test and two 6MWTs. Correlations between CPX VO2 peak and the predicted VO2 peak, coefficient of determination (R2), and mean absolute percentage error (MAPE) scores were calculated. P‐values were set at 0.05. A total of 106 participants aged 62.5 ± 11.5 years completed the tests. The mean VO2 peak from CPX testing was 16.4 ± 3.9 mL/kg/min, and the mean 6MWT distance was 419.2 ± 93.0 m. The predicted mean VO2 peak (mL/kg/min) by Burr et al., Ross et al., Adedoyin et al., and Cahalin et al. was 22.8 ± 8.8, 14.6 ± 2.1, 8.30 ± 1.4, and 16.6 ± 2.8. A significant correlation was observed between the CPX test VO2 peak and predicted values. The mean difference (0.1 mL/kg/min), R2 (0.97), and MAPE (0.14) values suggest that the Cahalin et al. equation provided the best predictive validity. Conclusions The equation provided by Cahalin et al. is simple and has a strong predictive validity, and researchers may use the equation to predict mean VO2 peak in patients with HF. Based on our observation, equations to predict individual maximal oxygen uptake should be used cautiously.

Abstract
BACKGROUND: The maintenance of maximal aerobic speed (MAS) until exhaustion is an important parameter for the evaluation of sports performance and prescription and planning of training. OBJECTIVE: To validate a 6-minute race test (6MRT) as a predictor of MAS in university endurance athletes. METHODS: Twenty two university endurance athletes (12 males and 10 females) were part of the study. The design was pre-experimental. The primary variables were the time of maintenance of the MAS on the field through a Time Limit Test (Tlim test), and the VO2 max (laboratory and field). The statistical analysis of the time and ventilatory variables was carried out using descriptive statistics; the comparison between males and females for all variables was carried out through a t-Student test for independent samples (p< 0.05). RESULTS: The performance in the Tlim test was 356.4 ± 52.9 and 327.0 ± 120.2 s in males and females, respectively. CONCLUSION: Based on the time of maintenance of the MAS (Tlim test), the 6MRT is a valid test to determine the MAS in university endurance male athletes. However, the MAS in university endurance female athletes must be evaluated with a shorter test (between 5 and 5.30 minutes long).

Pereira DDA, Correia Júnior JL, Carvas Junior N, Freitas-Dias RD. Reliability of questionnaire The International Fitness Scale: a systematic review and meta-analysis. EINSTEIN-SAO PAULO 2020; 18:eRW5232. [PMID: 32725055 PMCID: PMC7394011 DOI: 10.31744/einstein_journal/2020rw5232] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Accepted: 11/29/2019] [Indexed: 11/21/2022] Open
Abstract
Objective To perform a systematic literature review and meta-analysis to investigate the reliability of The International Fitness Scale questionnaire for assessing overall physical fitness and related components. Methods PubMed®, BIREME, SciELO, EMBASE, SPORTDiscus, LILACS and Cochrane databases were searched using the following search terms: “The International Fitness Scale”, “International Fitness Scale” and “IFIS”. Article selection and data extraction were performed according to the following eligibility criteria: reliability and/or validity study of the measure tools of The International Fitness Scale; adoption of the The International Fitness Scale as a reference criterion (gold standard) and being an original article. Quality of the study was considered based on Assessment of Reliability Studies. Data analysis used Kappa coefficient of agreement, Cochran and the Higgins I2 test. Sensitivity analysis was conducted using the withdrawal model. Results A total of seven articles were included in the analysis. Test-retest reliability coefficients ranged from 0.40 to 0.99, with most studies achieving values ≥0.60, indicative of moderate to substantial reliability. Conclusion In spite of appropriate test-retest scores attributed to most reliability indicators, heterogeneity among the studies remained high. Therefore, further studies with low risk of bias are needed to support the reliability of the self-reported The International Fitness Scale.

Abstract
Marins, EF, David, GB, and Del Vecchio, FB. Characterization of the physical fitness of police officers: a systematic review. J Strength Cond Res 33(10): 2860-2874, 2019-Physical fitness tests (e.g., aerobic power, muscular endurance, and flexibility tests) are commonly used to assess the ability of police officers to perform work-related tasks. The purpose of this study was to describe, from a systematic literature review, data related to police physical fitness. The research was conducted in 5 electronic databases to search for original studies that measured physical fitness (aerobic and anaerobic capacity, strength, endurance, power, flexibility, agility, and speed) of police officers, as well as the article references. Original studies assessing objective measures of physical fitness in police officers were included, with no date restriction. Fifty-nine articles were included in the review. The studies mostly measured cardiorespiratory fitness indirectly, strength, and muscular endurance, as well as other performance components (body composition, power, flexibility, speed, agility, and anaerobic profile), with police officers generally presenting values similar or above the average of the general population. It can be concluded that intervention studies are needed to promote and incorporate programs related to improvement or maintenance of physical fitness in police officers, which would result in health benefits and specifically improvement in performance of specific tasks of police work. This review provides summary information to assist in the selection of physical fitness tests for police populations. Still, these findings have practical applications for public security agencies and its personnel responsible for the development and implementation of physical programs in policemen population.

Abstract
INTRODUÇÃO: testes diretos são considerados "padrão ouro" para determinar variáveis fisiológicas, porém o seu custo financeiro é elevado e há a necessidade de mão de obra especializada para sua operacionalização. Sendo assim, os testes indiretos são utilizados pela maioria dos profissionais de Educação Física como uma alternativa acessível à falta da medida direta.OBJETIVO: comparar os valores de consumo máximo de oxigênio (VO2máx) determinados diretamente por um sistema de espirometria com valores determinados a partir de protocolos indiretos.MÉTODOS: participaram 15 pessoas do gênero masculino (27,4 ± 3,5 anos), fisicamente ativas, que realizaram o teste incremental em esteira rolante para determinação direta do VO2máxcom analisador de gases. Os testes para predição do VO2máxforam: ErgoPC; Polar Fitness Test; testes do banco e de Cooper. Foi utilizada a estatística descritiva (média ± desvio padrão - DP); a esfericidade foi testada pelo teste de Mauchly, os métodos foram comparados por ANOVA de medidas repetidas com o ajuste de Bonferroni para comparações múltiplas. A normalidade dos dados foi aferida pelo teste de Shapiro-Wilk e também foi aplicado o teste coeficiente de correlação de Pearson, adotando-se p<0,05.RESULTADOS: o valor médio de VO2máxdireto foi de 55,8 ± 6,1 ml•kg-1•min-1 e os valores para os testes indiretos, percentual de subestimação e coeficiente de correlação, foram, respectivamente: ErgoPc 33,7 ± 4,5 ml•kg-1•min-1 (39,6%; r = 0,71; p<0,001); Polar Fitness Test53,2 ± 6,4 ml•kg-1•min-1 (4,6%; r = 0,64; p = 0,774); teste do banco 48,8 ± 6,3 ml•kg-1•min-1 (12,5%; r = 0,60; P=0,001) e de Cooper 43,9 ± 7,9 ml•kg-1•min-1 (21,4%; r = 0,65; p<0,001).CONCLUSÃO: os métodos indiretos podem sugerir sobrecarga de treino inferior ou superior para adaptações fisiológicas pretendidas por subestimarem o direto, sendo o Polar Fitness Test o mais indicado para uso diário, pois apresentou valores mais próximos ao valor direto.
