“…In congruence with the views of Fox (1992) and research conducted by others (Harris, 1995;Crowhurst et al, 1993;Parcel et al, 1987) the results of this study suggest that the idea of allocating large chunks of time for health-promoting activity and integrating health-related fitness content within lessons aimed primarily at teaching pupils the skills and strategies needed to participate in different sports and activities is very difficult to implement and may well be unworkable. Our research indicates that the original NCPE Working Group may have been ambitious in suggesting that pupils' activity levels in many curriculum activities can be of the duration and intensity needed to improve their cardiovascular fitness (Department of Education and Science and the Welsh Office, 1991a).…”

“…On the other hand, findings from older students (n = 26), with a wider age range (approximately 11 to 19 years), were mixed. A total of 15 findings from 14 studies showed that PE had a neutral effect on students' CRF (n = 15) [14,22,[25][26][27][28][29][30][31][32][33][34][35][36]. While, 11 findings from nine studies reported that PE had a positive effect in children's and adolescents' CRF [26][27][28][36][37][38][39][40][41].…”

Promoting health-related cardiorespiratory fitness in physical education: A systematic review

et al. 2020

View full text Add to dashboard Cite

Background This article aimed to systematically review the contribution of physical education (PE) classes to improve cardiorespiratory fitness (CRF) in children and adolescents; and to define potentially relevant factors for promoting CRF in PE classes. Methods Studies were identified from searches in ERIC, PubMed, SPORTDiscus, and Web of Science databases. Primary source articles, relating PE classes and CRF, published up to July 2019 in peer-reviewed journals were eligible for inclusion. Specific inclusion criteria were: (a) having cross-sectional or longitudinal and observational or interventional study designs; (b) targeting school-aged children or adolescents; (c) measuring CRF, heart rate or CRF test results as an outcome; (d) having statistical analyses of the CRF, heart rate or CRF test results outcomes reported; (e) focusing on PE classes or PE interventions that did not extended time or frequency of the classes; and (f) published in English, French, Portuguese, or Spanish. Results A total of 24 studies met the inclusion criteria. Overall, 10 studies have found a neutral effect of PE classes in students' CRF, eight studies found that PE indeed contributed to the improvement of CRF and six studies revealed mixed findings, when PE classes where controlled for others variables (e.g. body mass index, intensity). Higher intensity PE classes consistently demonstrated contributions to improving students' CRF. Conclusion Review findings suggest that PE classes can contribute to the improvement of students' CRF. Intensity, age and weight status were identified as potentially relevant factors for promoting CRF in PE classes. To improve CRF, higher intensity classes should be provided.

“…Por apresentar um baixo custo e não requerer técnicas invasivas 6,7 , o PDFC, frequentemente identificado de forma visual, passou a ser amplamente utilizado por técnicos e treinadores para estimativa do segundo limiar de transição metabólica 8 . Evidências também foram descritas quando analisada a porção inferior da curva FC/CTC 9,10 .

“…Quando confrontados os resultados dos trabalhos que descreveram a relação FC/CTC em sua parte inferior 9,10 , com os da parte superior 2 , fica a sugestão de que essa relação possa ser descrita por uma função sigmóide, em forma de "S". De fato, Lima 3 sugeriu a utilização do ajuste sigmóide de Boltzmann para caracterizar o comportamento da FC durante teste progressivo máximo em cicloergômetro.…”

Resumo -O propósito deste estudo foi analisar o comportamento da frequência cardíaca (FC) versus a carga de trabalho crescente (CTC) em teste de esteira, utilizando três modelos matemáticos (linear, linear com dois segmentos de reta e sigmóide) e verificar qual o melhor modelo que possibilita a identificação de um limiar de FC que pudesse servir de preditor para os limiares ventilatórios (LV 1 e LV 2 ). Vinte e dois homens realizaram um teste incremental (re-teste: n=12), com velocidade inicial de 5,5 km.h -1 e incrementos de 0,5 km.h -1 a cada minuto, até a exaustão. Medidas contínuas de FC e trocas gasosas foram convertidas para médias de 5 e 20 segundos. Somatória dos resíduos quadrados e quadrado médio do erro foram usados para verificar o melhor ajuste. A relação FC/CTC foi melhor representada pelo modelo Lin 2 no grupo teste e re-teste (p<0,05). Foi possível identificar um ponto de deflexão de FC, utilizando o modelo Lin 2 (limiar de FC) em todos os indivíduos no teste (164 ± 16,6 bpm; 83,6% FC MÁX ) e no re-teste (162 ± 20,0 bpm; 83,9% FC MÁX ). O limiar de FC (Lin 2PDFC ) ocorreu a 9,2 ± 1,3 km.h -1 (67,9% Vel MÁX ) e foi menor que o LV 2 (LV 2 = 10,6 ± 1,5 km.h -1 ; 77,3% Vel MÁX ; p< 0,05), mas não diferente de LV 1 (8,4 ± 1,2 km.h -1 ; 61,6% Vel MÁX ; p> 0,05) . Durante teste incremental em esteira, a relação FC/CTC parece ser bem descrita por uma função linear com 2 segmentos de reta, a qual permite a determinação de um limiar de FC que se aproxima do LV 1. Palavras-chave: Ajuste sigmóide de Boltzmann; Ergometria; Teste de esteira rolante; Esforço físico; Frequência cardíaca (retest group: n=12) Abstract -The objective of this study was to analyze the heart rate (HR) profile plotted against incremental workloads (IWL) during a treadmill test using three mathematical models [linear, linear with 2 segments (Lin 2 ), and sigmoidal], and to determine the best model for the identification of the HR threshold that could be used as a predictor of ventilatory thresholds (VT 1 and VT 2 ). Twenty-two men underwent a treadmill incremental test
