Hi David Can't help you on this one, but there's lots of information about "exercise on the job" (so to speak) for injury prevention (VDT workers and so on). See, for example: Guo, L., Genaidy, A.M., Warm, J., Karwowski, W., and Hidalgo, J. 1992. Effects of jobsimulated flexibility and strength=flexibility training protocols on maintenance employees engaged in manual handling operations. Ergonomics, 35: 1103–1117. Lee, K. et al. 1992. a review of physical exercises recommneded for VDU workers. Applied Ergonomics:22:117-123 Robert JJ et al. 1995. Effect of a work hardening programme on cardiovascular fitness and muscular strength. Spine, 20:1187-1193 Some general principles for sedentary workers in static postures are: Chronically shortened and tense muscles must be stretched and relaxed The spine must be mobilised to reeuce compressive stress Chronically stretched or relaxed muscles must be contracted or strengthened to maintain posture Exercises must involve the lower limbs to promote venous return Bob ----- Original Message ----- From: "David McFarlane" <[log in to unmask]> To: <[log in to unmask]> Sent: Wednesday, August 27, 2008 6:22 AM Subject: Exercise Work-Breaks Dear All, In his book "Secrets of Soviet Sports Fitness and Training" (1987) Yessis claimed that in much of the USSR exercise breaks replaced coffee breaks (p 22). He said that the Soviets believed that exercise work-breaks could "improve productivity while enhancing physical and mental health" (ibid, p 25). For a seamstress the exercise program was designed specifically to reduce fatigue in the parts of the body used in the job and to move those body parts that "remain completely inactive" during work. Similarly specific programs were designed for secretaries, assembly workers and welders. Unfortunately Yessis did not provide any references or further details about the format of these Soviet "exercise work-breaks". Does anyone know anything about them?
