Altitude negates the benefits of aerobic training on the vascular adaptations in rats

Article Abstract:

A study was carried out to investigate the effect of living and training at moderate altitude on aortic vasoreactivity, considering that chronic hypoxia exposure and endurance training are able to generate opposite effects on the systemic vascular reactivity. Results have practical significance for aerobic performance as aortic vasoreactivity adaptations after altitude training could contribute to limit blood delivery to exercising muscles.

Transient decrease of neutrophil chemotaxis following aerobic exercise

Article Abstract:

A study is conducted to look at the differential effect of different chemoattractants on neutrophil migration following aerobic exercise, to determine the recovery time and to understand the role of the cell skeleton behind the impaired chemotaxis. The conclusions reveal that the impaired chemotactic response, observed 24 hours after exercise is similar using different chemoattractments.

Accuracy of VO2max prediction equations in older adults

Article Abstract:

The accuracy and bias of prediction equations in older, deconditioned men and women are explored. The predictors of VO2max are examined to understand that which variable affected respiratory fitness in the elderly.
