“…Therefore, future long term missions to space require more time efficient and reliable training countermeasures. After 1-6 months in space the relative decrease in muscle performance was generally larger than the relative decrease in the volume of corresponding muscle groups (Antonutto et al 1999;Zange et al 1997). However, in contrast to voluntary muscle performance representing a complex neuromuscular process, muscle volume is an only muscle specific variable.…”

“…Exercise countermeasures onboard the former Russian space station Mir and the current International Space Station ISS include treadmill running, cycling, and resistive exercise training (iRED) and are scheduled for 2 h per day. In part due to an insufficient performance of the recommended program (Pierre et al 2006), these countermeasures insufficiently prevent the negative effects of unloading on leg muscle (Antonutto et al 1999;LeBlanc et al 2000LeBlanc et al , 2007Zange et al 1997). Therefore, future long term missions to space require more time efficient and reliable training countermeasures.…”

20-Hz whole body vibration training fails to counteract the decrease in leg muscle volume caused by 14 days of 6° head down tilt bed rest

A 6 degrees head down tilt bed rest (HDT) was used to simulate the effects of muscle unloading in space. We tested whether vibration training (VT) reduces the decrease in leg muscle volume induced by 14 days HDT. In two study phases eight healthy male subjects received both (1) HDT and VT or (2) HDT and a control intervention. Twice daily five intervals of 1 min VT were performed (20 Hz, 2-4 mm) in upright standing position followed by 1 min breaks in seated position. The control intervention included identical procedures except the vibration plate was off. Before and the day after HDT volumes of upper and lower leg muscles were measured using magnetic resonance imaging. HDT combined with control intervention caused a significant (P < 0.05) decrease in the volumes of muscles by -4 to -6.5%. VT failed to counteract the decrease in leg muscle volume induced by HDT.

“…Zange and colleagues 8 found that 6 months in space decreased peak force to 48 % in the soleus, with parallel changes in volume as high as 20%. Lambertz et al 9 investigated the effects of long term space flight (90-180 days) on functional measures of the human plantarflexor muscles in 14 cosmonauts before and 2-3 days after landing.…”

“…It should also be pointed out that onboard the MIR station, the Astronauts did not perform any exercise specifically aimed at preventing the decay of the explosive power of the lower limbs. This decay of muscle function has been attributed mainly to a resetting of the neuromotory control system, since the decrease of the muscle mass alone (from )9% to )13%, Zange et al 1997) did not completely justify these findings (Minetti 2002;Zamparo et al 2002).…”

Microgravity is an extreme environment inducing relevant adaptive changes in the human body, especially after prolonged periods of exposure. Since the early sixties, numerous studies on the effects of microgravity, during manned Space flights, have produced an increasing amount of information concerning its physiological effects, globally defined "deconditioning". Microgravity deconditioning of the cardiovascular system (CVD) is briefly reviewed. It consists of: (1) a decrease of circulating blood and interstitial fluid volumes, (2) a decrease of arterial blood diastolic pressure, (3) a decrease of ventricular stroke volume, (4) a decrease of the estimated left ventricular mass and (5) resetting of the carotid baroreceptors. The negative effects of microgravity deconditioning manifest themselves mostly upon the reentry to Earth. They consist mainly of: (1) dizziness, (2) increased heart rate and heart palpitations, (3) an inability to assume the standing position (orthostatic intolerance), (4) pre-syncopal feelings due to postural stress and (5) reduced exercise capacity. To avoid these drawbacks several countermeasures have been proposed; they will be briefly mentioned with emphasis on the "Twin Bikes System" (TBS). This consists of two coupled bicycles operated by astronauts and counter-rotating along the inner wall of a cylindrical Space module, thus generating a centrifugal force vector, mimicking gravity.
