Introduction: The values of cardiorespiratory physical fitness (APF) in youth have a high predictive value on the future suffering of cardiometabolic diseases. The objectives of this study are to explore and describe the levels of cardiorespiratory APF and its relationship with nutritional status, in higher education students from the province of Jujuy, Argentina. Materials and methods: 65 subjects of both sexes, mean age of 25.95 ± 6.50 years, belonging to the Higher Technical Degree in Sports Training were evaluated. Body weight (BW), height, body mass index (BMI), waist circumference (WC) and waist-height index (WTI) were evaluated, and maximum oxygen consumption (VO2max) was estimated through the test of Course Navette of 20 meters (CN20m). Results: Height, PC, BMI and average VO2max were 1.65 ± 0.09 m, 67.78 ± 11.44 kg, 24.80 ± 3.32 kg.m2 and 37.03 ± 5.84 ml. kg-1.min-1, respectively. Statistically significant differences were observed between both sexes for BMI and VO2max.

Para tanto, utilizou-se da pesquisa descritiva com abordagem qualitativa, com coleta de dados por meio de entrevistas semiestruturadas realizadas com os professores e monitores. Os dados foram analisados conforme proposta de Bardin (2009). O planejamento e estruturação do PST Universitário foram realizados pelo coordenador, de acordo com as diretrizes do programa, que não prevê a participação do professor e dos monitores. De acordo com relato dos entrevistados, a formação não foi realizada conforme diretrizes, mas as reuniões de planejamento se mostraram significativas para a formação profissional. O principal impacto do programa avaliado foi na oferta de prática esportiva como direito. Dessa forma, conclui-se que o PST Universitário contribui para o acesso ao esporte educacional do corpo discente, bem como para a formação profissional, conforme previsto nas diretrizes. Contudo, faz-se necessário a participação dos professores na construção do planejamento, haja vista que na implementação existe uma dissociação entre quem planeja e executa.
