Brief Summary:
The aims of the study are twofold. In the cross-sectional approach (Part I), the study will be conducted in an older population to assess the association of physical fitness on different parts of the human vascular bed. In the interventional approach (Part II), it aims to investigate whether and to what extent advanced vascular ageing (AVA) in older subjects with increased cardiovascular risk can be reversed by regular walking- based high intensity interval training.

Cardiovascular Disease Obesity Atherosclerosis Heart; Disease, Activity Other: Training or control condition Not Applicable

Detailed Description:

In the cross-sectional part the investigators analyze physical fitness, vascular health and further outcomes in a healthy older active, a healthy older sedentary and a obese sedentary group with increased cardiovascular risk. The investigators will analyze large and small artery function, physical fitness and activity as well as inflammatory parameters in these three groups. Here the investigators will investigate the influence of physical activity and inflammatory parameters on the vascular health in different beds.

In the intervention part the older sedentary group with increasing cardiovascular risk (OSR) will be randomized in a control and an intervention group. The intervention group will get a high intensity interval training which is walking based and individual adjusted. The control group will get general lifestyle recommendations. After 12 weeks of training OSR group will be tasted again. The aim of the second part is to assess the effect of high intensity interval training on vascular health and inflammatory parameters.

Primary Outcome Measures :
  1. Change of pulse wave velocity (m/s) [ Time Frame: Change from baseline pulse wave velocity at 12 weeks ]
    Measured at local, central and peripheral site

Secondary Outcome Measures :
  1. Change of augmentation index (AIx@75) in % [ Time Frame: Change from baseline augmentation index at 12 weeks ]
    AIx and AIx@75 will be measured by using the gold standard device for single measurements (SphygmoCor®)

  2. Change of arteriolar to venular diameter ratio (AVR) in µm [ Time Frame: Change from baseline AVR at 12 weeks ]
    Dynamic and static retinal vessel analyzes will be investigated

  3. Change of physical activity in METs per week [ Time Frame: Change from baseline physical activity at 12 weeks ]
    The Freiburger Questionnaire of physical activity and inactivity and an accelerometer for seven days will be used to measure physical activity.

  4. Change of physical fitness in VO2max [ Time Frame: Change from baseline VO2max at 12 weeks ]
    An individual treadmill ramp test will be used to investigate peak oxygen consumption and maximal heart rate.

Other Outcome Measures:
  1. Change of diastolic function parameters (E/A; E/E') [ Time Frame: Change from baseline parameters at 12 weeks ]

  2. Change of autonomic function in heart rate variability (HRV) in beats per minute (bpm) [ Time Frame: Change from baseline HRV at 12 weeks ]
    12-lead ECG monitoring

  3. Change of serum biomarkers (hs-CRP, IL-6, IL-10, TNF-α) [ Time Frame: Change from baseline serum biomarkers at 12 weeks ]
    Blood sampling

  4. Change of cognitive Function [ Time Frame: Change from baseline cognitive function at 12 weeks ]
    Executive function test battery
