The testing of the individuals included in the post-covid swim program started in March 2023, and lasted through April 2023 in Croatia (Zagreb) and Slovenia (Ljubljana, Velenje and Kranj). Participants were assessed on questionnaires (general socio-demographic questionnaire, multidimensional fatigue inventory questionnaire, general health status, physical activity, sleep patterns, and stress), anthropometric indices, spirometry, physical fitness and swimming tests both before (initial testing) and after the 8-week water exercise program (final testing).

Sixty-four participants (41 females, 23 males) from all countries participated in the initial assessments before the exercise/swimming programme begun. Apart from questionnaires, physical fitness testing was included and consisted of: aerobic capacity tests (6 minute walk and 2 minutes stepping), flexibility (sit-and-reach test), handgrip strength, strength and endurance of lower limbs (30-second chair squats), abdominal strength (sit-ups) and swimming distances of 50 and 100 metres. Moreover, participants were measured for the anthropometric indices including the body height, body mass, and body fat percentage. Participants also underwent spirometry testing; the lung function tests that measure the air that is expired and inspired, which consisted of forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), which is the maximum amount of air that can be exhaled when blowing out as fast as possible.

Majority of the initially tested individuals were included in the systematic training program for 8 weeks that included swimming and exercises in the water. All tests and assessments were repeated directly after the exercise program was finished (final testing).

The results of the testing will be presented in the following tables and graphs.
