    (2024) Cofré-Bolados, Cristian; Vidal Díaz, Félix; Herrera Valenzuela, Tomás; Farias Valenzuela, Claudio; Espinoza Salinas, Alexis; Galeano-Rojas, Dilan
    Maximum oxygen consumption VO2max has represented a fundamental reference when measuring cardiorespiratory fitness in different sports. The aim of this study was to present the results of ergometry tests with gas analysis in athletes who exceeded 70 ml/kg/min in VO2max, analyzing the correlations between VO2max and metabolic, cardiovascular, and respiratory parameters. The study was of a descriptive correlational type, and 27 male athletes participated. The r Pearson test was applied to determine the correlation between the variables. In the result analysis, correlations were determined: small between Age and VO2max (r = -0.238; p = 0.24); large between VO2max vs VO2VT1 (r = 0.741; p<0.001); VO2max vs VO2VT2 (r = 0.808; p<0.001); and VO2VT1 vs VO2VT2 (r = 0.783; p<0.001). Mean between VO2max and HR (r = 0.340; p = 0.09); large between absolute VO2max and VO2/HRmax (r = 0.840; p<0.001); small between VO2max and VE (r = 0.214; p = 0.30); small between VO2max and BR (-0.184; p = 0.37); small between VE and RR% (

    Influence of outdoor education learning models and mental toughness on cardiorespiratory fitness levels
    (Universidad de Murcia, Servicio de Publicaciones, 2024) Hernawan, Hernawan; Nugraha, Hartman; Ridwan, Mukhtar; Makadada, Fredrik Alfrets
    This study aimed to determine the influence of the outdoor education learning models and mental toughness on cardiorespiratory fitness (CRF) levels. A quasi-experimental method was used, employing a 2x2 factorial design. The 2x2 factorial design in this study involved two learning models: the TGT (Team Games Tournament) and STAD (Student Teams Achievement Division), along with two levels of mental toughness: high and low. The sample consisted of 80 students from Jakarta State University, enrolled in recreational sports courses. The subjects in this study were given the TGT and STAD learning models over a period of 9 weeks. The tests administered during the pretest measured cardiorespiratory fitness using the Bleep Test and mental toughness using a questionnaire. The results showed that both the TGT and STAD outdoor education models have a statistically significant impact on students' CRF levels (p<0.05). Additionally, an interaction effect was observed between the learning model and the level of mental toughness (p<0.05). Specifically, the TGT model showed a greater influence on CRF in students with high mental toughness (p<0.05), while the STAD model was more effective in students with low mental toughness (p<0.05). Both the outdoor education learning model and mental toughness influence the level of CRF, suggesting that outdoor education can enhance CRF, which may positively affect academic performance and mental health of students.
