Aerobic and anaerobic energy expenditure during exhaustive ramp exercise.

Ramp tests are often manipulated so that oxygen uptake is able to interpret energy expenditure in its entirety. We hypothesized that oxygen deficits during ramp exercise to exhaustion would be significant, providing a more complete description of the types of energy expenditure available for this mode of testing. Oxygen deficits were obtained during a slow ramp (681 +/- 71 s) and a fast ramp (275 +/- 33 s) to exhaustion.

Prospective outcome evaluation of spinal cord stimulation in patients with intractable leg pain.

Study Design: The results of spinal cord stimulation were prospectively evaluated using both subjective patient self-report measures and objective physical functional testing.

Objectives: The purpose of this study was to evaluate prospectively the effects of spinal cord stimulation implantation, performed with the patient awake and providing feedback, in patients with primary reports of intractable leg pain.

Summary Of Background Data: Spinal cord stimulation has been used for treating chronic pain of many types.

Early changes in bone mineral density above a combined anteroposterior L4-S1 lumbar spinal fusion. A clinical investigation.

Study Design: Fifteen patients meeting rigid study entrance criteria for undergoing a combined anteroposterior L4-S1 spinal fusion as a first time operation were included in the study. Bone mineral density changes at adjacent segments (L3 and L2) were assessed by scanning patients in the anteroposterior and lateral projections before surgery and 3 and 6 months after surgery.

Objectives: To prospectively evaluate changes in bone mineral density at adjacent segments after lumbar spinal fusion and postoperative bracing.

Effect of a practical neck cooling device on core temperature during exercise.

Previous studies have documented the effectiveness of combined head and neck cooling in reducing thermal stress during exercise. However, these studies investigated low intensity exercise and devices that are not practical for use on a widespread basis during recreational exercise. In the present study, we investigated the effect of a commercially available, practical neck cooling device on core temperature during strenuous exercise.

Incidence and reasons for medical referral in a worksite health promotion program.

Abstract The purpose of this study was to examine incidence and reasons for medical referral as a result of screening performed in a worksite health promotion program. Screening consisted of a medical history questionnaire, blood lipid profile, a submaximal treadmill stress test to 85% of age-predicted maximal heart rate, and other fitness measures. Overall, 11.
