    Potencia aeróbica máxima en el obeso: Valores de referencia
    (2019) Cancino, Jorge; Olivares, Mariela; Maiz, Cristóbal; Soto, Johana; Palacio, Ana; Pino, Johanna
    Background: The evaluation of physical fitness is important to determine workloads and to assess the effectiveness of exercise interventions in obese people. Aim: To determine the maximum aerobic power output (MAPO) in overweight and obese individuals and to establish reference parameters for the Chilean population. Material and methods: One hundred five men and 218 women performed a cycle ergometer test up to 85% of their maximum heart rate. MAPO was determined by linear extrapolation of the theoretical maximum heart rate. Results: Among men, MAPO values were 234.9 ± 48.4 w for body mass index (BMI) values between 30 and 34.9 kg/m2, 235.1 ± 69.7 w for BMI between 35 and 39.9 kg/m2, 270.2 ± 86.5 w for BMI over 40 kg/m2. MAPO relative values were 2.27 ± 0.5, 2.16 ± 0.6 and 1.96 ± 0.8 w/kg, respectively. Among women, MAPO was 172.6 ± 36.1 w for a BMI < 30 kg/m2, 169.2 ± 39.4 w for BMI between 30 and 34.9 kg/m2, 179.5 ± 48.8 w f179.5 ± 48.8 w for BMI between 35 and 39.9 kg/m2 and 202.3 ± 57.3 w for BMI of 40 kg/m2 or over. The relative values were 2.33 ± 0.5; 2.02 ± 0.5; 1.91 ± 0.5 and 1.81 ± 0.5 w / kg (p < 0.05). Conclusions: MAPO estimation with a cycle ergometer test is well tolerated in overweight and obese individuals. MAPO decreased along with BMI increments in women. No association between BMI and MAPO in men was observed.

    Practices Used in Estimating the Cost of Capital and Investment Appraisal in the Chilean Forestry Sector
    (2015) Acuna, Eduardo; Cancino, Jorge; Vásquez Lavín, Felipe; Mena, Pablo; Sánchez, Karen
    The proper determination of cost of capital is crucial in the maximization of forest enterprises value as it depends on the capital budgeting decisions made by the managers. It is unknown whether the firm size has an effect on the techniques used to determine the cost of capital in the Chilean forestry sector. The main objective of this research was to determine the practices used by decision makers from the forestry sector to estimate the cost of capital and, at the same time, how their investments how evaluated. In order to carry out this study, a survey was conducted by using the SurveyMonkey online tool. The final survey consisted of 20 questions. A total of 189 people from 49 companies were registered. The study allows concluding that the net present value (NPV) is the main investment appraisal used by decision makers from the Chilean forestry sector. On the other hand, the estimation of the cost of capital is mostly performed by means of the Cost of Debt method. In addition, it was verified that there is a lack of knowledge on the budging techniques used worldwide.
