Objetivos: el propósito de este estudio fue establecer un protocolo intermitente indirecto para jugadores de baloncesto y generar una ecuación para predecir el VO2 max. (ml/kg/min). Materiales y Métodos: se seleccionaron 30 participantes del club deportivo Valdivia de baloncesto. Edad 15.90 ± 1.5 Años. Peso. 71.61 ± 12.3 (kg). Estatura. 178 ± 0.08. % (cm). Grasa 17.63 ± 2.5 (%). Masa muscular 41.43 ± 2.2 (%). VO2 57.37 ± 5.2 (ml/kg/min). Se realizaron dos pruebas, la primera, en el laboratorio se calculó el VO2 (ml/kg/min). directo, la prueba inicio a 6 km/h. Durante 1 min. Con inclinación 1°. durante toda la prueba. Con incrementos de velocidad en 7 km/h. Hasta la fatiga. Con el análisis de las variables se obtuvo el siguiente modelo de regresión (37,262 + -0,172 * peso + 1,901 * velocidad), p0.732, (SEE) 3.0. Sesgo cercano a cero 0.267 ml/kg/min, en Bland-Altman, con límites de concordancia de (-1.31 – 1.84). Conclusiones: los resultados demuestran que la prueba posee una alta confiabilidad y validez para evaluar el VO2 (ml/kg/min) en jugadores de baloncesto.
Goals: The purpose of this study was to establish an indirect intermittent protocol for basketball players and to generate an equation to predict VO2max. (ml/kg/min). Materials and methods: 30 participants from the Valdivia basketball sports club were selected. Age 15.90 ± 1.5. Weight (kg). 71.61 ± 12.3. Height (cm) 178 ± 0.08. % Fat 17.63 ± 2.5. % Muscle mass 41.43 ± 2.2. VO2 (ml/kg/min). 57.37 ± 5.2. Two tests were performed, the first, in the laboratory the direct VO2max was calculated, the test started at 6 km/h, for 1 min. With 1° inclination. With speed increments of 7 km/h. Until fatigue. With the analysis of the variables obtained, a multiple linear regression was performed, obtaining the following regression model (37,262 + -0,172 * weight + 1,901 * speed), p-value 0.003. Said equation was used in the second test to predict the VO2max. (ml/kg/min). With the proposed measurement protocol, level 1. Starting at 6 km/h. With increases of 1 km/h, duration of 1 min. Distance of 15m. 5 second breaks. Between speed series, until reaching fatigue. Results: The student’s t test for paired samples determined a mean of the differences of 0.26667, 95% CI. (-1.3082-1.8416). Standard deviation 4.2176. p-value >0.05, (SEE) 3.0. Bias close to zero 0.267 ml/Kg/min, in BlandAltman, with limits of agreement of (-1.31 – 1.84). Conclusions: The results show that the test has a high reliability and validity to evaluate the Vo2max (ml/kg/min). In basketball players.
