Abstract Background The maximum oxygen uptake (VO2max) during cardiopulmonary exercise testing (CPET) is considered the best measure of cardiorespiratory fitness. Aim To provide up-to-date reference values for the VO2max per kilogram of body mass (VO2max/kg) obtained by CPET in the Netherlands and Flanders. Methods The Lowlands Fitness Registry contains data from health checks among different professions and was used for this study. Data from 4612 apparently healthy subjects, 3671 males and 941 females, who performed maximum effort during cycle ergometry were analysed. Reference values for the VO2max/kg and corresponding centile curves were created according to the LMS method. Results Age had a negative significant effect (p < .001) and males had higher values of VO2max/kg with an overall difference of 18.0% compared to females. Formulas for reference values were developed: Males: VO2max/kg = − 0.0049 × age2 + 0.0884 × age + 48.263 (R2 = 0.9859; SEE = 1.4364) Females: VO2max/kg = − 0.0021 × age2 − 0.1407 × age + 43.066 (R2 = 0.9989; SEE = 0.5775). Cross-validation showed no relevant statistical mean difference between measured and predicted values for males and a small but significant mean difference for females. We found remarkable higher VO2max/kg values compared to previously published studies. Conclusions This is the first study to provide reference values for the VO2max/kg based on a Dutch/Flemish cohort. Our reference values can be used for a more accurate interpretation of the VO2max in the West-European population.

Purpose:To examine variations in physical, physiological, and performance parameters over an annual training cycle in a world champion rowing crew.Methods:Four world-class rowers, all of them members of the men’s heavyweight quadruple sculls squad who are current world rowing champions, were assessed 3 times at regular 4-mo intervals during the 2011 season (November 2010, March 2011, and July 2011). Physical assessments included stature, body mass, body composition, whereas physiological and performance assessments obtained during an incremental rowing ergometer test to exhaustion included maximum oxygen uptake and anaerobic gas-exchange threshold with corresponding power output values.Results:Body mass (∼95 kg) and body composition (∼12% body fat) remained stable over the annual training cycle. Power output at anaerobic gas-exchange threshold increased +16% from November to July, whereas the corresponding oxygen uptake, expressed as a percentage of maximum oxygen uptake, increased from 83% to 90%. Maximum oxygen uptake decreased from 6.68 L/min in November to 6.10 L/min in March before rising to 6.51 L/min in July. The corresponding power output increased steadily from 450 W to 481 W.Conclusion:Seasonal variation in body mass and body composition of 4 examined world-class rowers was minimal. Oxygen uptake and power output corresponding to anaerobic threshold continuously increased from off-season to peak competition season. Seasonal variation in maximum oxygen uptake reached ∼10%; however, it remained above 6 L/min, that is, the value consistently observed in top caliber heavyweight rowers regardless of the time of the assessment.

The cardiorespiratory responses to weight reduction due to physical exercise were examined in fourteen women with obesity, aged 36 to 67 years (Body Mass Index, 32.4 ± 1.4 kg/m2). The patients were instructed to exercise at approximately 60% of maximum oxygen uptake for 2 h every day for approximately 3 months. To evaluate physical strength, a graded cycling exercise test was performed both before and after the exercise period, monitoring gas exchange, ventilation, and heart rate. After the exercise period the body mass index and percentage fat both decreased by 11% and 18%, respectively ( P < 0.001), although lean body mass did not change; maximum oxygen uptake and maximum heart rate did not change significantly, but peak ventilation equivalent, maximum metabolic equivalent and maximum load increased by 12%, 14% and 11%, respectively ( P < 0.05, P < 0.001 and P < 0.001, respectively). Maximum oxygen uptake per unit body weight increased by 5% ( P < 0.001). These results suggest that weight reduction as a result of exercise improves cardiorespiratory function in middle-aged women with obesity.

The Relationship

The main objective of this study was to analyse the relationship between the performance in a maximum incremental test for lifeguards, the IPTL, and the effectiveness of a 200 m water rescue on the beach. Initially, 20 professional lifeguards carried out the IPTL in the pool and then they performed a 200 m water rescue on the beach. The maximum oxygen uptake (VO2max) in the IPTL was estimated. In both tests, heart rate (HR), blood lactate (La) and time achieved were measured. The VO2max estimated in the IPTL (VO2IPTL) was 44.2 ± 4.7 mL·kg·min−1, the time reached in the IPTL (TimeIPTL) was 726 ± 72 s and the time spent in the rescue (TimeRescue) was 222 ± 14 s. The results showed that the time reached in the pool (TimeIPTL) was the best predictor variable of the performance in water rescue (TimeRescue) (R2 = 0.59; p < 0.01). A significant correlation was also observed between the estimated maximum oxygen uptake and the beach rescue performance (R2 = 0.37; p = 0.05). These results reveal that the IPTL, a maximum incremental test specific to lifeguards, allows the estimation of the effectiveness of a 200 m rescue on the beach.

Abstract Objective: To determine the level of cardiovascular fitness in young adults, and to find the relationship of maximum oxygen uptake with body mass index and physical activity. Methods: The cross-sectional study was conducted at two private universities in Islamabad, Pakistan, from January to June 2019, and comprised subjects of both genders aged 18-25 years with normal cardiopulmonary system. Physical activity was measured usint the short form of International Physical Activity Questionnaire, while maximum oxygen uptake was measured using the Bruce protocol. Data was analysed using SPSS 24. Results: Of the 321 subjects, 59(18.4%) were males and 262(81.6%) were females. The overall mean age was 21.15±1.73 years. Overall, 190(57.3%) subjects had normal body mass index, 86(26.8%) had high level of physical activity, and 85(26.5%) had moderate level. With respect to to maximum oxygen uptake, 28(47.5%) of the males were in the superior category, while 72(27.5%) women were in the good category. All the vitals along with dyspnoea and fatigue showed significant difference (p?0.05) except oxygen saturation (p=0.062). Maximum oxygen uptake showed negative weak (p=0.40) correlation with body mass index, and weak, positive and significant correlation (p=0.007) with physical activity. Conclusion: Majority of the young adults were found to be active as indicated by the levels of their maximum oxygen uptake and physical activity. Significant correlation was found between cardiovascular fitness and physical activity. Continuous...
