Resumo: | This study measured the peak force (PF) in cadet inline speed skaters (ISS) and verified the physical measures that determine athletes' performance on the Isometric Mid-Thigh Pull Test (IMTP) through a multivariate regression and discriminant canonical analysis. A total of 36 high-performance male (n= 18; age= 17.4± 1.21 years; body mass= 65.1± 6.18 kg; height= 168.6± 5.1 cm) and female (n= 18; age= 17.4± 1.23 years; body mass= 55.5± 4.4 kg; height= 158.6± 5.2 cm) athletes were measured two times (with a 3-day interval). All participants performed the IMTP and sit-and-reach (SR) tests, and an evaluator performed anthropometric circumference measurements on their thighs and calves. The main results indicated that males showed a higher PF on the test (m= 59.0± 3.9 N/kg vs. f= 50.4± 5.8 N/kg; p≤ 0.001) and retest (m= 59.1± 4.2 N/kg vs. f= 51.9± 6.6 N/kg; p≤ 0.001). In the first, thigh circumference (X2= 29.01, p≤ 0.001, R2= 0.74) had an overall 91.7% prediction. The second model included using the SR and thigh circumference (X2= 49.91, p≤ 0.001, R2= 1.0) showed an overall prediction of 100.0%. The thigh circumference matrix showed better predictive power for (coefficient= 7.158) male and female IMTP performance. In conclusion, despite the gender differences, the thigh circumference is a good predictor for PF in cadet ISS athletes. |

Um total de 36 atletas de alto nivel, homens (n=18; idade=17,4±1,2 anos; massa corporal = 65,1±6,2 kg; altura = 168,6±5,1 cm) e mulheres (n=18; idade = 17,4±1,2 anos; corpo massa = 55,5±4,4 kg; altura = 158,6±5,2 cm) foram medidos duas vezes (intervalo de 3 dias). Todos os participantes realizaram os testes de IMTP e sentar e alcançar (SR), um avaliador realizou medidas antropométricas de circunferência nas coxas e panturrilhas. Os principais resultados indicaram que o sexo masculino apresentou maior FP no teste (m: 59,0±3,9 N / kg vs. f: 50,4±5,8 N/kg; p≤0,001) e reteste (m: 59,1±4,2 N/kg vs. f: 51,9±6,6 N/kg; p≤0,001). No primeiro modelo, a circunferência da coxa (X2=29,01, p≤0,001, R2=0,74) apresentou capacidade preditiva de 91,7% do desempenho. O segundo modelo incluído usando o SR e a circunferência da coxa (X2=49,91, p≤0,001, R2=1,0) apresentou capacidade preditiva em 100,0% para o desepenho no teste. A matriz da circunferência da coxa apresentou melhor poder preditivo para (coeficiente = 7,158) desempenho IMTP masculino e feminino. Em conclusão, apesar das diferenças de gênero, a circunferência da coxa é um bom preditor para FP em atletas cadetes do ISS.Edições Sílabas Didáticas2022-06-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.6063/motricidade.24626eng2182-29721646-107XAedo-Muñoz, EstebanReyes-Galvez , NataliaLópez-Guzmán, Chris MauroArgothy-Bucheli, RodrigoPrat-Luri, AmayaBustamante-Garrido, AlejandroMiarka, BiancaBrito, Ciro Joséinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-12-08T13:45:13Zoai:ojs.revistas.rcaap.pt:article/24626Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:30:15.744882Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
