NCT01476033

  Purpose

The investigators investigate the impact of an encapsulated fruit, berry and vegetable juice powder concentrate on oxidative stress, inflammation and blood flow before and post exercise in overweight, middle-aged, women.

Main hypotheses (H1):

  • The nutraceutical has an impact on oxidative stress reduction.
  • The nutraceutical has an impact on inflammation.
  • The nutraceutical has an impact on blood flow and microcirculation.
  • Walking exercise for 30 minutes has an impact on oxidative stress- and inflammation markers.
  • Walking exercise for 30 minutes has an impact on blood flow and microcirculation
  • The combination of nutraceutical supplementation + walking exercise for 30 minutes has an impact on oxidative stress- and inflammation markers, and on blood flow/microcirculation.

Condition Intervention
Oxidative Stress
Inflammation
Dietary Supplement: nutraceutical group

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Basic Science
Official Title: Impact of Encapsulated Fruit, Berry and Vegetable Juice Powder Concentrate on Oxidative Stress, Inflammation and Blood Flow Before and Post Exercise in Overweight, Middle-aged, Women.

Primary Outcome Measures:
  • Carbonyl groups on protein, oxidized LDL, Malondialdehyde, TNF-alpha, IL-6, Trombelastometry and peripheral microcirculation [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Carbonyl groups on protein as indicators of protein oxidation; oxidized LDL, Malondialdehyde as indicators of Lipidoxidation; TNF-alpha, IL-6 as indicators of inflammation; Trombelastometry: clotting time, thrombocyte ahesion, trombocyte aggregation from whole blood as indicators for blood flow and hemostasis; Peripheral microcirculation in subcutis as indicator for blood flow in peripheral subcutis.
