JOURNAL FREE ACCESSThis study investigated the clinical usefulness of near infrared spectroscopy for evaluating tissue-oxidative metabolism by a non-invasive method, particularly in the medial vastus muscle. Two kinds of quadriceps exercises (maximal isometric contraction and setting repetition) were performed by 14 healthy male volunteers. Test-retest reliability and correlation with muscular strength were evaluated. As the recovery index in the O2 content curve after the exercises, the time to reach the apparent level showed better reproducibility than other indices. The bottom value of O2 content in the maximal isometric contraction correlated well with the peak torque of muscular strength. The greatest variance of O2 content in the repetitive setting exercise correlated well with the recovery time after the exercise. This method can be useful in many clinical situations to evaluate the muscular fatigue and the recovering ability.View full abstractDownload PDF (1160K) -

JOURNAL FREE ACCESSThe major purpose of this investigation was to assess the early effects of lung resection on pulmonary function and the anaerobic threshold (AT) by means of a cycle ergometer exercise test. Eighty-eight patients (mean age: 61 years) who underwent lung resection without severe cardiopulmonary or other complications were evaluated pre- and postoperatively. We assessed the patients postoperatively after a mean period of 17 days, when they had recovered sufficiently to be able to walk on a level floor at an ordinary pace without dyspnea (Grade 2 by Hugh-Jones). After resection, vital capacity was significantly reduced, but minute ventilation was not reduced indicating ventilative compensation by ventilation rate for loss of tidal volume. However, oxygen consumption (VO2) and exercise load at the AT were reduced even though heart rate (HR) did not change after resection. On the other hand, postoperative VO2 at rest was the same as before resection despite of an increase in HR. Thus, the early effect of lung resection on pulmonary function was compensated for by activated ventilation, however, it appears that postoperative reduction in exercise load at the AT might be mainly due to deteriorations of ventilation equivalent and cardiac output.View full abstractDownload PDF (678K) -

JOURNAL FREE ACCESSTo investigate the systemic and local factors effecting on the bone mineral density of patients with rheumatoid arthritis (RA), we measured the bone mineral density of forty patients with RA at spine, radius and calcaneus by the dual energy X-ray absorptiometry. Quantitative ultrasound was also performed to measure stiffness index of calcaneus. The Z-score of bone density was compared to the serum levels of interleukin-6, TNF-α and intact osteocalcin, and to the activity of daily living which were separately assessed by upper or lower limb function. The effects of corticosteroid were also examined. The decrease in bone mineral density was the most prominentin calcaneus (Z score=-1.3), and was minimal in spine (Z score=-0.2). There was no relationships between the serum levels of cytokines or intact osteocalcin and bone mineral density except a third distal of the radius. The function of upper or lower limb correlated with the bone mineral density of respective limb. The influence of corticosteroid appeared to decrease the stiffness index of calcaneus. These results showed that disuse of the extremity was the most important factor for osteoporosis of patients with RA and that corticosteroid seemed to have relations with the quality of bone.View full abstractDownload PDF (953K)
