  1. PA-level physical activity level according to ACSM/AHA questionnaire, SEE self-efficacy expectations, PREP readiness to change – prepared, CONF readiness to change – confident, BMI body max index, PCS physical component summary – SF-36, PABL physical activity at baseline
  2. Cut-points regarding positively assessed values were: SEE ≥4.77 points, PREP > 86 mm, CONF > 68 mm, BMI < 30, PCS ≥ 47.06 points. Cut-point regarding low PABL was < 2 points
  3. aP values were determined by Chi-square test for independence
  4. Statistical significance was set at p ≤ 0.05. Statistical significant p-values are presented in bold numbers
