Running Effect on Cardiovascular and Muscular Parameters

Effect of 16 Weeks of Running Exercise on Parameters Related to the Cardiovascular System, Blood and Muscle in Untrained Males 30-50 Years Old. A Randomized Controlled Study

The purpose of the study is to determine the effect of 16 weeks of running exercise on various parameters related to heart, vascular systems, blood, and muscle in untrained males 30-50 years old.

Further, the investigators assess which of the above mentioned parameters may explain the increase of running performance most accurate.

Inclusion Criteria:

• males
• untrained (< 2 endurance exercise sessions/week)
• 30-50 years old

Exclusion Criteria:

• pathological changes of the heart
• inflammable diseases
• medication/diseases affecting cardiovascular system and muscle
• very low physical capacity (< 100 Watt at ergometry)
• obesity (BMI > 30 kg/m2)
• more than 2 weeks of absence during the interventional period
• more than 2 exercise session beside the intervention
• contraindication related to MRI-assessment (i.e. claustrophobia, magnetizable intracorporal artefacts)
