Maximal aerobic speed (MAS) represents the minimal speed where a further increase in speed will not result in a further increase in oxygen consumption (V̇O 2 ). MAS is determined from the relationship between maximal V̇O 2 (V̇O 2max ) and running economy, the latter also expressed as the O 2 cost of running. There is no standardized method for determination of MAS in the literature, but three approaches are more dominant: the...
Physiological determinants and energy system contribution in short- and middle-distance cycling performanceNARA Subscribed
Purpose The purpose of this study was to investigate the contribution of aerobic and anaerobic energy release on cycling performance in 10 to 180 s. Methods 18 male cyclists from recreational- to elite level participated in this cross-sectional study. The cyclists were tested in oxygen cost of cycling (C), peak oxygen uptake (VO 2peak ), maximal sprint power (MSP), and five short time trials (TT): 10 s (10TT), 30 s (30TT), 60...
Determining physiologic variables for changes in 800-m running and 800-m ski ergometer performanceNARA Subscribed
Purpose This study investigates associations between changes in 800 m time trial performance in running or ski ergometer double poling, and changes in physiologic variables after a seven-week observational period. Forty six athletes ranging from recreational to elite level, participated in either a run (RUN) or a ski ergometer (SKI) observational study. Methods The participants performed pre- and post-tests in; 800-m time tria...
Maximal aerobic and anaerobic power and time performance in 800 m double poling ergometerNARA Subscribed
The purpose of this study was to investigate to what extent aerobic power (MAP), maximal anaerobic power (MANP), anaerobic capacity measured as time to exhaustion at 130% MAP (TTE), and maximal accumulated oxygen deficit (MAOD) correlated with 800 m double poling time trial performance (800TT) in a ski ergometer. A second aim was to investigate the relationship between TTE and MAOD, and to what extent TTE and MAOD would relate...
Maximal strength training in patients with inflammatory rheumatic disease: implications for physical function and quality of lifeNARA Subscribed
Purpose Patients with inflammatory rheumatic disease (IRD) have attenuated muscle strength in the lower extremities, resulting in impaired physical function and quality of life. Although maximal strength training (MST), applying heavy resistance, is documented to be a potent countermeasure for such attenuation, it is uncertain if it is feasible in IRD given the pain, stiffness, and joint swelling that characterize the populati...
