Hematologic and Biochemical Data on Healthy Individuals Participating in a Physical Conditioning Program

摘要

Fifty-eight (58) relatively sedentary adults who were recruited into a physical fitness program involving 10 weeks of closely supervised, standardized and monitored exercises, were evaluated, physically, hematologically, and biochemically before and after participation in the program. Most of the participants were subjected to 16 different laboratory tests both before and after participation; a smaller group was subjected to as many as 20 tests. Physical responses to the conditioning program included a loss of body fat averaging 5%, a 3% of total body weight, a 32% excess body weight loss, decreased pulse rates at peak exertion of 5% and following the recovery period of 11%, an increased aerobic capacity (VO2 max) of 8%, and an increased rate of sit-up performance of 28%. Statistically significant changes in laboratory data included drops in total hemoglobin and MCHC, increased red cell P50 and LDH, decreased serum cholesterol and triglycerides, increased serum HDL-cholesterol, and decreased plasma phosphorus.
