The purpose of this study is to examine the effect of 30-minute duration submaximal running and roller skiing exercises, which are among the most important aerobic exercise models in cross-country skiers, on lactic acid levels. The study group comprised 6 female and 4 male athletes (age: 16.87 +/- 1.87 years, body height: 168.35 +/- 5.66 cm, body weight: 56.83 +/- 7.1 kg) who competed in cross-...
This investigation examined the effect of intramuscular iron injections on aerobic-exercise performance in iron-deficient women. Sixteen athletes performed a 10-min steady-state submaximal economy test, a VO2max test, and a timed test to exhaustion at VO2max workload. Subjects were randomly assigned to an iron-supplemented group (IG) receiving intramuscular iron injections or to a placebo group...
abstract objective children suffering from cerebral palsy (cp), exhibit movement limitations and physiological abnormalities as compared to normal individuals. the objective of this study was to assess mechanical efficiency and certain cardiovascular indices before and after an exercise-rehabilitation program in children with dipelegia spastic cerebral palsy (experimental group) in comparison w...
Background: Tobacco contains carcinogens such as NNK (nicotine-derived nitrosamine ketone) that makes induction of lung cancer by changing the stimulation of IL-10 expression. The aim of this study was to investigate changes in resting levels of IL-10 in lung tissues of rats exposed to NNK after a 12-week aerobic submaximal swimming training. Methods: For this purpose, 46 Wistar rats were rand...
To the Editor: Denervation affects greatly cardiac function in HTx recipients. However, it is not the main determinant of their reduced aerobic performance (1, 6). Indeed, the latter depends on complex interactions among cardiac, pulmonary, neurohormonal, vascular, and skeletal muscle function (or “dysfunction”). The relative role of each of these factors may vary depending on donor’s heart cha...
STUDY OBJECTIVE To determine whether an aerobic endurance training program (AET) in comparison to normal daily activities improves exercise capacity in lung transplant recipients. PATIENTS AND STUDY DESIGN Nine lung transplant recipients (12+/-6 months after transplant) were examined. All patients underwent incremental bicycle ergometry with the work rate increased in increments of 20 W every...
We compared the effectiveness of an aerobic and nonaerobic exercise in the treatment of clinical depression in women. A total of 40 women, screened on the Research Diagnostic Criteria for major or minor depressive disorder, were randomly assigned to an 8-week running (aerobic), weight-lifting (nonaerobic), or wait-list control condition. Subjects were reassessed at midand posttreatment, and at ...
OBJECTIVES To evaluate weighted stair climbing exercise (SCE) as a means of increasing lower extremity muscle power in mobility-limited older people. DESIGN Single-blinded, randomized controlled pilot study. SETTING Human physiology laboratory of a metropolitan university. PARTICIPANTS Forty-five community-dwelling people aged 65 and older who had baseline mobility limitations manifested ...
The purpose of this study was to examine the influence of age and moderate-intensity exercise training on heart rate variability (HRV), and to elucidate further the mechanism of training-induced bradycardia and cardioprotection. Electrocardiograms were recorded from 12 young (18-24 yrs) and 12 mature (29-43 yrs) individuals during supine rest and submaximal moderate exercise. Recordings were ob...
In patients with chronic heart failure whose cardiac output response to exercise is impaired, determination of anaerobic threshold may provide a useful and objective approach to grade the severity of heart failure. In such patients performing upright treadmill exercise to exhaustion, this study examined the reproducibility of the response of cardiac output and mixed venous lactate concentration...
