Journal ArticleDOI
Muscle atrophy and bone loss after 90 days' bed rest and the effects of flywheel resistive exercise and pamidronate: results from the LTBR study.
Jörn Rittweger,Harold M. Frost,Hans Schiessl,Hiroshi Ohshima,Björn Alkner,Per A. Tesch,Dieter Felsenberg +6 more
TL;DR: It is suggested that both countermeasures are only partly effective to preserve BMC (FW and Pam) and mCSA of the lower leg during bed rest and the partial efficacy of flywheel exercise as well as the bones' response to unloading per se underlines the importance of mechanical stimuli.
Journal Article
Effects of Low-Intensity Cycle Training with Restricted Leg Blood Flow on Thigh Muscle Volume and VO2MAX in Young Men
Takashi Abe,Satoshi Fujita,Toshiaki Nakajima,Mikako Sakamaki,Hayao Ozaki,Riki Ogasawara,Masato Sugaya,Maiko Kudo,Miwa Kurano,Tomohiro Yasuda,Yoshiaki Sato,Hiroshi Ohshima,Chiaki Mukai,Naokata Ishii +13 more
TL;DR: The results suggest that low-intensity, short-duration cycling exercise combined with BFR improves both muscle hypertrophy and aerobic capacity concurrently in young men.
Journal ArticleDOI
Bisphosphonates as a supplement to exercise to protect bone during long-duration spaceflight
Adrian LeBlanc,Toshio Matsumoto,Jeffrey A. Jones,Jay R. Shapiro,Thomas Lang,L. Shackelford,Scott M. Smith,H. Evans,E. Spector,Robert Ploutz-Snyder,Jean D. Sibonga,Joyce H. Keyak,Toshitaka Nakamura,Kenjiro Kohri,Hiroshi Ohshima +14 more
TL;DR: The combination of exercise plus an antiresoptive drug may be useful for protecting bone health during long-duration spaceflight.
Journal ArticleDOI
Intravenous pamidronate prevents femoral bone loss and renal stone formation during 90-day bed rest.
Yukiko Watanabe,Hiroshi Ohshima,Koh Mizuno,C Sekiguchi,Masao Fukunaga,Kenjiro Kohri,Jörn Rittweger,Dieter Felsenberg,Toshio Matsumoto,Toshitaka Nakamura +9 more
TL;DR: Pamidronate prevented femoral bone loss and renal stone formation, but resistive exercise showed little effects.
Journal ArticleDOI
Effect of short-duration spaceflight on thigh and leg muscle volume.
Hiroshi Akima,Yasuo Kawakami,Keitaro Kubo,Chiharu Sekiguchi,Hiroshi Ohshima,Akira Miyamoto,Tetsuo Fukunaga +6 more
TL;DR: The results suggest that atrophy as a result of at least 2 wk of spaceflight varied among individuals and muscle groups and that the degree of atrophy appeared to be greater than that induced by 20 d of bed rest.
