The ACE ID genotype and muscle strength and size response to unilateral resistance training

Article Abstract:

The association of the angiotensin converting enzyme (ACE) insertion/deletion ( I/D) polymorphism is examined with the response of the elbow flexors to resistance training. The results indicate that the response of muscle to resistance training is not highly related to the ACE I/D polymorphism, whereas the contralateral effects of unilateral training are associated with the presence of D-allele.

Chemoreflex and metaboreflex responses to static hypoxic exercise in aging humansr

Article Abstract:

Hypothesis was tested that aging decreases the contribution of metaboreceptors to sympathetic responses during exercise in hypoxia. Aging reduces sympathetic reactivity to isometric handgrip, but does not prevent the metaboreceptors to remain the main determinant of sympathetic activation during exercise in hypoxia.

Respiratory muscle strength may explain hypoxia-induced decrease in vital capacity

Article Abstract:

The possible contribution of a hypoxia-related decrease in respiratory muscle strength is investigated. The result shows that a decrease in respiratory muscle strength may contribute to the decrease in forced vital capacity (FVC) observed at high altitude.
