Vibration as an exercise modality: how it may work, and what its potential might beJörn Rittweger
Institute of Aerospace Medicine, German Aerospace Center, Linder Höhe 1, Koln, 51147, Germany
Eur J Appl Physiol 108:877-904. 2010..Moreover, literature suggests that vibration is beneficial to reduce chronic lower back pain and other types of pain. Other future indications are perceivable...- Structural analysis of the human tibia in men with spinal cord injury by tomographic (pQCT) serial scansJörn Rittweger

Bone 47:511-8. 2010..Finally, the drastically reduced s04:s38 vBMC.tot ratio observed in the SCI group in this study provides a rationale to scrutinize this Capozza index also in other studies as a general indicator of immobilisation-induced bone loss... - Persisting side-to-side differences in bone mineral content, but not in muscle strength and tendon stiffness after anterior cruciate ligament reconstructionJörn Rittweger
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, Manchester, UK
Clin Physiol Funct Imaging 31:73-9. 2011..These findings suggest that impaired recovery of BMC following ACL reconstruction is not because of lack of recovery of knee extensor strength or patellar tendon stiffness. The responsible mechanisms still remain to be determined... - Muscle tissue oxygenation and VEGF in VO-matched vibration and squatting exerciseJörn Rittweger
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, Manchester, UK
Clin Physiol Funct Imaging 30:269-78. 2010..Most likely, the transient response is because of local vascular regulatory mechanisms and due to muscle contraction mechanics. This might become clinically relevant under pathological conditions, e.g. in vascular disorders... - Effects of smoking on tibial and radial bone mass and strength may diminish with ageRob C I Wüst
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, Manchester M1 5GD, United Kingdom
J Clin Endocrinol Metab 95:2763-71. 2010..The purpose of the study was to assess the effect of cigarette smoking on indicators of bone strength across a wide age range, controlling for physical activity and neuromuscular performance... - Prevention of bone loss during 56 days of strict bed rest by side-alternating resistive vibration exerciseJörn Rittweger
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, Manchester, UK
Bone 46:137-47. 2010..These results suggest that the combined countermeasure applied in this study is effective to prevent bone losses from the tibia. This underlines the importance of mechanical usage for the maintenance of the human skeleton... - Noninvasive estimation of myosin heavy chain composition in human skeletal muscleBostjan Simunic
Institute for Kinesiology Research, Science and Research Centre Koper, University of Primorska, Koper, Slovenia
Med Sci Sports Exerc 43:1619-25. 2011..Because there are only a few techniques available that noninvasively and accurately provide an estimate of muscle fiber type composition, the development of additional and alternative approaches is required... - Forearm and tibial bone measures of distance- and sprint-trained master cyclistsDesiree C Wilks
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, Manchester, United Kingdom
Med Sci Sports Exerc 41:566-73. 2009..This study compared bone measures of sprint- and distance-trained cyclists competing at World Master Track Championships, along with sedentary controls (30-82 yr), and examined the associations of bone measures with age... - Vascular adaptations induced by 6 weeks WBV resistance exercise trainingTobias Weber
Department of Space Physiology, German Aerospace Center, Institute of Aerospace Medicine, Cologne, Germany
Clin Physiol Funct Imaging 33:92-100. 2013..Despite numerous studies addressing the acute cardiovascular effects of WBV training, very little is known regarding long-term adaptations in healthy humans... - Effects of alfacalcidol on circulating cytokines and growth factors in rat skeletal muscleJanwillem Testerink
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, John Dalton Building, Oxford Road, Manchester, M5 1GD, UK
J Physiol Sci 61:525-35. 2011..The atrophy and loss of body mass in the presence of supra-physiological levels of vitamin D are primarily due to a reduced food intake... - Bone loss in the lower leg during 35 days of bed rest is predominantly from the cortical compartmentJörn Rittweger
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, Oxford Rd, Manchester, M1 5GD, UK
Bone 44:612-8. 2009..The latter will lead to cortical thinning, a factor that has been associated with the risk of fracture and with osteoarthritis... 
Sprint and endurance power and ageing: an analysis of master athletic world recordsJörn Rittweger
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, All Saints Campus, Manchester M15 6BH, UK
Proc Biol Sci 276:683-9. 2009..However, it is unclear as to which are the governing mechanisms that cause the different systems in our body, responsible for sprinting and for endurance performance, to be affected by ageing in a remarkably uniform way...- Variation in the determinants of power of chemically skinned type I rat soleus muscle fibresSally F Gilliver
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, John Dalton Building, Oxford Road, Manchester M5 1GD, UK
J Comp Physiol A Neuroethol Sens Neural Behav Physiol 197:311-9. 2011..Approximately 16% of the variation in Po could be explained by variation in the proportion of attached cycling cross-bridges (f/(f+g(1))), but the origin of most of the variance in Po remains unknown... - The specific role of gravitational accelerations for arterial adaptationsTobias Weber
German Aerospace Center, Institute of Aerospace Medicine, Space Physiology, Cologne, Germany
J Appl Physiol 114:387-93. 2013.... - Relationship between ventilatory function and age in master athletes and a sedentary reference populationHans Degens
Institute for Biomedical Research into Human Movement and Health, Manchester Metropolitan University, John Dalton Building Chester Street, Manchester, M1 5GD, UK
Age (Dordr) 35:1007-15. 2013..Life-long exercise does not appear to attenuate the age-related decrease in ventilatory function. The better respiratory function in master athletes than age-matched sedentary people might be due to self-selection and attrition bias...

Proc Inst Mech Eng H 226:838-47. 2012..5 microm, respectively. Small markers (Ø3-8 mm) yielded better accuracy and repeatability than the larger marker (Ø10.5 mm). We conclude that the proposed system is capable of recording minor displacements in a relative large volume...- Bone loss from the human distal tibia epiphysis during 24 days of unilateral lower limb suspensionJörn Rittweger
Manchester Metropolitan University, IRM, Hassall Road, Alsager ST7 2HL, UK
