Introduction and aim. Arterial stiffness (AS) has been associated with reduced cardiorespiratory fitness (CRF). The aim of this study was to verify if there is a relationship between augmentations index (AIx), as an index for AS assessment, and CRF in individuals with type 2 Diabetes Mellitus (T2DM). Material and methods. Observational cross-sectional study including 32 individuals diagnosed with T2DM who performed two evaluations: 1. Arterial stiffness assessment using SphygmoCor and 2. CRF throughout a cardiopulmonary exercise test on a treadmill ergometer. Oxycon Mobile® device was used to obtain oxygen uptake consumption at peak (V˙O2peak); oxygen uptake efficiency slope (OUES) determined by linear regression in reason of the logarithmic transformation of the ventilation and V˙O2 obtained every minute of exercise test. Statistical analysis comprised Pearson’s Correlation and linear regression analysis performed in SigmaPlot. Results. There was a significant correlation between AS and CRF: AIx and OUES; AIx@75 and; OUES. In linear regression, AIx was determinant for V˙O2peak and OUES – AIx and; AIx@75 and V˙O2peak. Conclusion. AS was associated with CRF in individuals with T2DM. These results contribute to the body of evidence linking arterial functional properties to CRF and suggests greater attention for this important index.

Introduction: Health perception is a complex issue and determined by various factors. When assessing health there are positive, negative and intermediate measurements, as well as health indicators including the following criteria: subjective, objective and social. Purpose: To determine the relationship between subjective health assessment, physical fitness and cardiorespiratory fitness. Materials and Methods: The study included 1.000 high school adolescents from Poland and Ukraine. Two questionnaires were used in the study: an original questionnaire, and a standardized 20 m shuttle run test with PACER (Progressive Aerobic Cardiovascular Endurance Run), enabling indirect assess of VO2 max. Results: Significant differences between subjective health assessment, physical fitness and cardiorespiratory fitness were found. The best health self-assessment and physical fitness, the best cardiorespiratory fitness results were obtained among adolescents. Polish youth better assessed their health in comparison to the peers from Ukraine. Conclusions: There is a relation between subjective health assessment and the objective parameters. When measuring health state of individuals or groups it is worth consider a subjective criterion of health.

Introduction This study evaluated the effect of a 12-month physical exercise intervention accompanied by a 12-month followup evaluating stress symptoms (SS), mental resources (MR) and cardiorespiratory fitness (CRF) in healthy, working adults. We hypothesized that the stress symptoms would decrease and mental resources would increase during the intervention and that these results are associated with changes in CRF. Material and methods The study group included healthy adults (N = 371). Three hundred thirty eight participants (212 women, 126 men) were allocated in the exercise group and 33 in the control group (17 women and 16 men). For the analysis, the exercise group was divided into subgroups according to the baseline SS and MR. Stress symptoms and MR were measured using the Occupational Stress Questionnaire. Results During the 12-month exercise intervention, SS decreased by 16% (p < 0.0001), MR increased by 8% (p < 0.0001) and CRF increased by 7% (p < 0.0001) in the exercise group, while no changes occurred in the control group (ANCOVA, p < 0.01). In the exercise group, the results (SS, MR, and CRF) remained improved during the follow-up. There was a positive correlation between the change in SS and the change in CRF (r = 0.19, p < 0.01). In the subgroup having the highest SS at baseline, SS during the intervention decreased most (26%) (ANCOVA, p < 0.0001). Conclusions One year physical exercise intervention improved mental well-being among working adults and this was associated with an improvement in cardiorespiratory fitness. The positive changes remained after the 12-month follow-up.
