Metabolic changes during cold water immersion. 1995

Department of Zoology, University of Trondheim, Norway.

This study was conducted in order to compare the metabolic responses of individuals exposed to long duration cold water immersion under two experimental conditions: 1) Heat loss compensated by shivering thermogenesis, and 2) heat loss compensated by intermittent periods of exercise. Nine subjects participated in two experimental trials 1) Subjects wearing insulated survival suits who did perform mild leg cycling during immersion 2) Subjects wearing insulated survival suits who did not perform exercise. Blood was sampled pre- and postimmersion. Blood was assayed for free fatty acids (FFA), lactate, creatine kinase and glucose. Intermittent periods of physical activity during cold water immersion resulted in a higher increase in FFA than during inactivity. In lactate, glucose, and creatine kinase there were no significant differences between the changes from pre- to postimmersion under the two conditions.

D003402	Creatine Kinase	A transferase that catalyzes formation of PHOSPHOCREATINE from ATP + CREATINE. The reaction stores ATP energy as phosphocreatine. Three cytoplasmic ISOENZYMES have been identified in human tissues: the MM type from SKELETAL MUSCLE, the MB type from myocardial tissue and the BB type from nervous tissue as well as a mitochondrial isoenzyme. Macro-creatine kinase refers to creatine kinase complexed with other serum proteins.
