title: [Blood circulation in healthy inhabitants of the arid zone of Turkmenistan. Report 2. Use of controlled exercise test in persons with good and insufficient adaptation to high environmental temperature].
abstract: Bicycle ergometry was performed in 143 normal male residents of Ashkhabad in different seasons of the year. In cool weather, the direction and magnitude of hemodynamic response to exercise in Ashkhabad residents were similar to those of people from milder climatic zones. In summer, exercise-related systolic and diastolic blood pressure and the stroke index were smaller as compared to the respective values of the cool season. During the transition period (i.e. first hot summer days), blood pressure and the stroke index were the lowest, and the heart rate was somewhat increased. In hot weather, exercise produced a greater reduction in the circulating blood volume and a greater increase in the hematocrit value. Thirteen (9%) subjects with poor tolerance of hot weather were identified in the screened population. In these, hemodynamic shifts were similar to those observed in most normal subjects during inadequate acclimatization of the first hot summer days.
