Body composition and total body, femoral, and spinal BMD (grams per square centimeter) were measured in vivo by dual-energy X-ray absorptiometry (PIXImus2; GE Lunar) at 12 and 18 weeks of age in the exercise experiment; at 13 and 16 weeks of age in the axial compression experiment; and at 1, 4, 12, and 18 months for the aging experiment.
BMcG, EH, LK and SE participated in the exercise experiment and collection of samples.
All exercise experiments were performed on males.
Postbreakfast plasma glucose and insulin concentrations on day 2 were lower in the daily exercise experiment compared with the control and nondaily exercise treatment (P < 0.05 for both glucose and insulin) (Fig. 2).
Interestingly, in the resistance-type exercise experiment, average glucose concentrations and the prevalence of hyperglycaemia were significantly reduced during the subsequent nocturnal and morning periods (12 18 h later and 18 24 h later, respectively) following exercise (Table 2).
It should be noted, however, that in the knee extension exercise experiment S1P and SA1P were not released across the leg at any workload (including the 30-minute rest period separating each exercise) which indicates that skeletal muscle did not directly contribute to elevated levels of sphingoid base-1-phosphates in plasma observed after exercise on a rowing ergometer.
(Sweet cherries, by the way, have shown little efficacy in exercise-related experiments).
The nutrition and exercise experiment is designed to determine whether drastic changes in lifestyle and eating habits can prevent the need for angioplasty and heart bypass surgery.
Since retiring from the Army in 2000, General Schoomaker has remained active, participating in almost 12 training exercises, experiments or war games sponsored by the Joint Forces Command, officials said.
(only for the daily exercise experiment).
