Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
• The first experimental group (NW) - this group consisted of 20 women who underwent a 6-month Nordic walking training.
• The second experimental group (R) - this group consisted of 18 women who underwent a 6-month training on a cycloergometer.
NW group
The subjects in the NW group underwent 6-month (72 sessions) Nordic walking training. Classes were held outdoors (park) 3 times a week from April to September 2019. The duration of each training unit was 1 hour, which consisted of:
• introductory part (about 10 minutes) - to warm up and prepare the body, including strengthening and stretching exercises (Borg 6-8 scale),
• main part (about 45 minutes) - in this part, the participants marched using the Nordic walking technique with the intensity defined at the level of the first ventilation threshold (VT1), during which the optimal heart rate (HR) was determined (Borg scale 10-12) ,
• final part (approx. 5-10 minutes) - calming down, consisting of stretching, breathing and relaxation exercises (Borg 6-8 scale).
All sessions were providing by physiotherapists in groups of no more than 10 people. Session attendence checklist were checked before start the every session.
Before starting the program, the respondents participated in 3 classes (weekly 1-hour) aimed at getting acquainted with the correct technique of Nordic walking. Classes were providing by physiotherapists.

Group R.
The subjects in group R underwent a 6-month training (72 sessions) on cycloergometers. Classes were held in a gym equipped with stationary bicycles, 3 times a week from April to September 2019. The duration of each training unit was 1 hour, which consisted of:
• introductory part (approx. 10 minutes) - aimed at warming up and preparing the body for the main part of the training. The subjects pedaled with an intensity determined on the Borg scale at 6-8,
• main part (about 45 minutes) - in this part, the subjects pedaled with the intensity defined at the level of the first ventilation threshold (VT1), during which the optimal heart rate (HR) was determined (Borg 10-12),
• final part (approx. 5-10 minutes) - for calming down, during which the participants will pedal with an intensity determined on the Borg scale at 6-8.
All sessions were providing by physiotherapists in groups of no more than 10 people. Session attendence checklist were checked before start the every session.

Summary
Brief summary
Regular physical activity such as nordic walking or cycloergometer training contributes to improvement biochemical, morphological, rheological properties of blood, vitamin D levels, general physical fitness and quality of life.
The aim of the study was to assess the impact of the nordic walking training and of the cycloergometer training on biochemical, morphological, rheological properties of blood and vitamin D levels in women aged 65-75 years.
55 women, aged 65-74, participated in the study. The first group consisted of 20 women who underwent 6-month nordic walking training. The second group consisted of 18 women who underwent 6 month of cycloergometer training. The control group consisted of 17 women who did not undergo any intervention. Blood samples was collected three times for each subject to analyze biochemical, heamtological and rheological properties of blood as well as vitamin D concetration- before the start of the project, after 3 month and at the end after 6 month. At the same time intervals, physical fitness by means of Senior Fitness Test and quality of life with SF-36 questionnaire of study participants were tested. In the experimental groups, the trainings took place three times a week, lasted one hour, and the intensity was determined at 60-70% HRmax.
