Although maximal oxygen uptake (VO2 max) has been measured for almost 100 years, it is unknown when 'true' VO2 max is attained. Primary (the VO2 plateau) and secondary criteria are used to confirm VO2 max incidence, but frequency of the VO2 plateau varies, and secondary criteria are relatively invalid. The verification test (VER) seems to elicit similar estimates of VO2 max versus the incremental value (INC), yet existing data are limited by small populations and use of inadequate criteria to confirm 'true' VO2 max...

The effect of tapering following a period of high-volume sprint interval training (SIT) and a basic volume of aerobic training on performance and muscle adaptations in moderately trained runners was examined. Eleven (8 males, 3 females) runners (maximum oxygen uptake (VO2-max): 56.8±2.9 mL·min(-1)·kg(-1); mean±SD) conducted high-volume SIT (HV; 20 SIT sessions; 8-12 x 30-s all-out) for 40 days followed by 18 days of tapering (TAP; 4 SIT sessions; 4 x 30-s all-out). Before and after HV as well as midway through and at the end of TAP, the subjects completed a 10-km running test and a repeated running test at 90% of vVO2-max to exhaustion (RRT)...

BACKGROUND: Exercise-based cardiac rehabilitation tends to reduce mortality. However, it requires medium/long-term adherence to regular physical exercise. It is relevant to identify the variables that affect adherence to an supervised exercise program (SEP). OBJECTIVE: To evaluate the influence of pre-participation levels of aerobic and non-aerobic physical fitness components in medium-term adherence to SEP. METHODS: A total of 567 SEP participants (65 ± 12 years) (68% men) were studied...

BACKGROUND: Patient-reported dyspnea plays a central role in assessing cardiopulmonary disease. There is little evidence, however, that dyspnea correlates with objective exercise capacity measurements. If the correlation is poor, dyspnea as a proxy for objective assessment may be misleading. OBJECTIVE: To compare patient's perception of dyspnea with maximum oxygen uptake (MaxVO2) during cardiopulmonary exercise testing (CPET). METHODS: Fifty patients undergoing CPET for dyspnea evaluation were studied prospectively...

PURPOSE: Fitness level modulates the physiological responses to exercise for a variety of indices. While intense bouts of exercise have been demonstrated to increase tear osmolarity (Tosm), it is not known if fitness level can affect the Tosm response to acute exercise. This study aims to compare the effect of a maximal incremental test on Tosm between trained and untrained military helicopter pilots. METHODS: Nineteen military helicopter pilots (ten trained and nine untrained) performed a maximal incremental test on a treadmill...

Independently, cardiorespiratory fitness (CRF), C-reactive protein (CRP) and leukocyte count have been shown to predict cancer death. Little is known about the joint impact of CRF and prediagnostic markers of inflammation, particularly leukocyte count and CRP, and their prognostic value with cancer death. The aim of this study was to explore the association between prediagnostic inflammatory markers and CRF with cancer mortality. A population-based cohort of 2270 men from Eastern Finland with no cancer history at baseline participated in the study...
