Brief Summary:
While "conditioning" by exercise training has been widely evaluated, the available literature on "passive deconditioning" (i.e. forced deconditioning) is predominately limited to studies with or with almost complete mechanical and/or metabolic immobilization/sedation of the respective functional system (e.g. paralysis, bedriddenness). Vice versa, the effects of moderately long interruptions of dedicated types of exercise while maintaining everyday activity are rarely addressed. However, this topic is of high relevance, e.g. considering that breaks of health-related exercise programs due to increased family/occupational stress, vacation or temporary orthopedic limitation are rather frequent in everyday life. In the present project we aimed to determine the effects of 3 months of physical deconditioning due to COVID-19 induced lockdown after 13 month of high intensity endurance and resistance exercise in early postmenopausal women on parameters related to health and physical fitness.

Primary Outcome Measures :
  1. Body composition [ Time Frame: From intervention end to 3 months FU ]
    Body composition as determined by Dual-Energy x-Ray Absorptiometry

Secondary Outcome Measures :
  1. Hip-/Leg extension strength [ Time Frame: From intervention end to 3 months FU ]
    Hip-/Leg extension strength as determined by an isokinetic leg press

  2. Metabolic Syndrome [ Time Frame: From intervention end to 3 months FU ]
    cardio-metabolic risk factors summarized in the Metabolic Syndrome Z-Score according to the definition of the International Diabetes Federation

  3. Bone Mineral Density (BMD) [ Time Frame: From intervention end to 3 months FU ]
    BMD at the lumbar spine and total hip as determined by Dual Energy x-Ray Absorptiometry

  4. Menopausal symptoms [ Time Frame: From intervention end to 3 months FU ]
    Menopausal symptoms as determined by the "Menopausal Rating Scale" (MRS) with a scale from 0 (no complaints) to 4 (very serious complaints).

  5. Back and joint pain [ Time Frame: From intervention end to 3 months FU ]
    Back and joint pain as determined by a standardized pain questionnaire with a scale from 0 (never) to 7 (permanent) for pain frequency or 0 (no pain) to 7 (extremely) for pain severity.
