HSP expression in human leukocytes is modulated by endurance exercise

Article Abstract:

Heat shock/stress protein (HSP) expression in human leukocytes has been found to be modulated by endurance exercise. Temperature increase, oxidative stress and inflammatory reactions after endurance exercise were expected to stimulate synthesis of HSPs in peripheral blood leukocytes. Whether or not regular endurance training would influence HSP expression was of interest as well. Strenuous exercise increased HSP expression in blood immediately at the end of running, which shows a positive function of HSP in leukocytes of athletes to maintain function after heavy exercise. Downregulation of HSP-positive cells in trained athletes at rest is apparently because of adaptation mechanisms to regular endurance training.

Expression of the inducible nitric oxide synthase (iNOS) in human leukocytes: responses to running exercise

Article Abstract:

Vigorous exercise increases levels of inducible nitric oxide synthase (iNOS) in immune cells, according to a study of 10 runners competing in a half marathon. The effect of excess nitric oxide production on muscles is not known.

Evaluation of stress responses to interval training at low and moderate altitudes

Article Abstract:

An experiment was performed to determine whether extensive interval training performed with a similar lactate accumulation pattern between Sea Level (SL) and Altitude (ALT) correlates with similar hormonal, metabolic, and acute phase response in trained athletes. The conclusion identifies stress responses greater at ATL.
