Resumo: | The purposes of the study were to compare and correlate the running velocities associated with the maximal oxygen consumption (Vmax), anaerobic threshold (LL), ventilatory threshold (LV), critical velocity (CV), anaerobic work capacity (AWC) and oxygen cost during sub-maximal exercise (C). METHODS: Eight male physically active subjects (20.8±1.6 years; 74.3±14.9 kg), performed the following tests: 1) 500m and 3km time trial (Vm500 and Vm3km); 2) Incremental test on treadmill for of LL, LV, VO2max and Vmax identification; 3) sustained running at Vmax (Tmax) and identification of the time to VO2max and time at VO2max. The CV and AWC were obtained from linear regression (distance x time on 500m and 3km test). The C was determined as a ratio between sub-maximal running velocity and its VO2. RESULTS: A high correlation was verified for Vm3km and Vmax (r=0.83), Vm3km and VC (r=0.98), Vm500 and VC (r=0.90), Vm500 and Vm3km (r=0.92), and between Vm500 and Time to VO2max (r=0.69). No differences were observed between LL and LV (178.7±20.0 e 180.7±21.8m.min –1) (p>0.05). Also a high correlation between LL and Vmax¬ (r=0.91), CV (r=0.96), and Vm3km (r=0.96) were verified. The AWC was negatively correlated to running economy for those with higher aerobic capacity. CONCLUSION: The CV, AWC, Vm500 an Vm3km can be used for exercise evaluation and training prescription. Due the correlation with the C, the AWC may be an indicative of mechanical inefficiency. |

MÉTODOS: 8 homens fisicamente ativos (20,8±1,6 anos; 74,3±14,9kg) realizaram: 1) Corrida 3km e 500m máximos (Vm3km e Vm500). 2) Teste incremental em esteira para determinação do LL, LV, VO2max e Vmax. 3) Tempo de permanência na Vmax (Tmax), Tempo para atingir o VO2max e Tempo no VO2max. A VC e a CTAn foram obtidas (método linear) a partir dos testes de 3km e 500m. O C foi determinado dividindo-se a velocidade de corrida submáxima pelo respectivo VO2. RESULTADOS: Observou-se alta correlação entre Vm3km e Vmax (r=0,83), Vm3km e VC (r=0,98), Vm500 e VC (r=0,90) e entre Vm500 e Tempo no VO2max (r=0,69). Não foram verificadas diferenças entre LL e LV (178,7±20,0 e 180,7±21,8 m.min-1), sendo o LL altamente correlacionado com Vmax (r=0,91), VC (r=0,96) e Vm3km (r=0,96). Correlação positiva foi observada entre CTAn e C para indivíduos com maior aptidão aeróbia (r=0,79). CONCLUSÕES: As correlações apresentadas entre Vm500 e tempo no VO2max e entre Vm500 e VC indicam que exercícios de curta duração e alta intensidade são positivamente influenciados pela aptidão aeróbia. Devido a correlação significativa com o C, a CTAn se mostra como um possível indicador de ineficiência mecânica no exercício aeróbio.Universidade Estadual Paulista - Câmpus de Rio Claro2007-01-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionDocumento Avaliado por Paresapplication/pdfhttps://www.periodicos.rc.biblioteca.unesp.br/index.php/motriz/article/view/10210.5016/102Motriz.
