Lower-body negative pressure/ergometer exercise in bed rest: Effects on female orthostatic tolerance
Published on: 21st October, 2020
OCLC Number/Unique Identifier: 8689024101
Introduction: Alternatively using gradient lower-body negative pressure (LBNP) and ergometer exercise (LBNP + ergo) under a flight schedule framework was explored to detect its orthostatic capacity maintenance effects in female subjects after 15 days of -6° head-down bed rest (HDBR).
Methods: Twenty-two female university students were divided into a control group (n = 8), an LBNP group (n = 7), and an LBNP + ergo group (n = 7). Ergometer exercise consisted of an interval exercise protocol with 2 min intervals alternating between 41% and 70% VO2max. Gradient LBNP was decompressed in 10 mm Hg intervals to -40 mmHg every 5 min. intermittent ergometer exercise and LBNP were alternatively performed. Tilt test was performed 2 days before HDBR (R-2), on the day of HDBR termination (R+1), and 5 days after HDBR (R+5).
Results: Fifty percent of the participants (11/22) did not pass the tilt test on R+1. The orthostatic tolerance time decreased from 20 to 16.1 ± 2.1 min in the control group, to 10.0 ± 2.7 min in the LBNP group (p = 0.01) and to 16.3 ± 2.0 min in the LBNP + ergo group. The HRs and BPs were at similar level among three groups during tilt test on different test days. Compared with the control group, the LBNP + ergo group had higher SV and CO percentage changes at R+1(p < 0.023) and R+5 (p < 0.00001) during the tilt test.
Conclusion: LBNP combined with ergometer exercises fails to prevent orthostatic intolerance but it induced some positive hemodynamic changes during tilt test after 15 days HDBR.

The Journal Clinical Nephrology provides a good opportunity for readers to stay updated in the field of clinical nephrology. Additionally - it provides a good opportunity for authors to publish their work. 1. Publication of the accepted manuscripts is sufficiently rapid. 2. The trust factor between the journal and me, as an author, is very important and well preserved. 3. Peer review process very rapid and effective.

Publishing an article is a long process, but working with your publication department made things go smoothly, even though the process took exactly 5 months from the time of submitting the article till the time I have favourable response, the missing part is the peer review details, which is essential in self auditing and future improvement, overall experience was excellent giving your understanding of the situation of lack of financial institution support.
