The Role of Physical Fitness in Emotional Well-Being and Distress during Pregnancy: The GESTAFIT Project

Pregnancy involves various physiological, physical, and social changes that can impact the mental health of the woman, causing her to have a stressful experience. Physical fitness (PF) is postulated as a powerful marker of health in this population. Therefore, this longitudinal study examined the association of PF with maternal emotional well-being and ill-being outcomes at 16th and 34th gestational weeks (g.w.) in a sample of 158 pregnant women (32.9 +/- 4.7 years old). Self-reported PF was assessed with the valid and feasible International Fitness Scale [i.e., overall PF, cardiorespiratory fitness (CRF), muscular strength, speed-agility, and flexibility]; positive and negative affect, emotional intelligence, and resilience were measured using validated questionnaires specifically designed for this purpose. The results showed that women with greater overall PF and its components showed higher positive affect and lower negative affect (all, p < 0.05); greater emotional intelligence (all, p < 0.05); and greater resilience (all, p < 0.05), with similar results both in the 16th and the 34th g.w. These findings underscore the pivotal role of PF in promoting emotional health and resilience during pregnancy, thereby highlighting the need for integrating PF enhancement strategies in prenatal care programs.
