The Effect of a 10-Week Swimming Exercise Program on Emotional State in Female Sport Sciences Students

University students, particularly those navigating the demanding academic, social, and psychological landscape of higher education, are increasingly recognized as a population susceptible to significant stressors. These pressures can profoundly impact emotional wellbeing, manifesting as heightened levels of anxiety, depression, and even hopelessness. While the benefits of physical exercise for mental health are widely acknowledged, specific evidence regarding the impact of structured programs like swimming on distinct university subgroups has remained a gap in scientific literature. A recent study, published in Frontiers in Psychology, sought to address this by investigating the effects of a 10-week structured swimming exercise program on the emotional wellbeing of female students enrolled in a Faculty of Sport Sciences.

The research employed a rigorous experimental pretest-posttest control group design, a methodology renowned for its ability to establish causal relationships between an intervention and observed outcomes. Forty-two female students, aged between 18 and 22 years, were randomly allocated to either a supervised swimming exercise group or a control group. Over a period of 10 weeks, the intervention group engaged in supervised swimming sessions twice weekly, while the control group maintained their usual daily routines without any structured exercise intervention. The study meticulously assessed emotional status before and after the intervention using two established psychometric tools: the Beck Hopelessness Scale (BHS) to measure negative expectations about the future, and the Oxford Happiness Questionnaire—Short Form (OHQ-SF) to gauge positive affect and subjective wellbeing.

Key Findings and Intervention Impact

The statistical analysis, utilizing a mixed-design ANOVA, revealed significant interaction effects between time and group for both hopelessness and happiness. Notably, participants in the swimming exercise group experienced a statistically significant decrease in reported hopelessness levels. This reduction was substantial, with a large effect size indicated by partial eta squared (η²p = 0.30), suggesting that the intervention had a meaningful impact on this negative emotional indicator. In stark contrast, the control group, which did not participate in the structured swimming program, showed no significant change in their hopelessness scores.

Complementing these findings, the study also reported a significant increase in reported happiness levels among the swimming exercise group. This positive emotional shift was characterized by a very large effect size (η²p = 0.41), underscoring the potent influence of the swimming program on subjective wellbeing. Similar to the hopelessness measure, the control group did not exhibit any significant changes in happiness scores over the 10-week study period. These results collectively point towards a clear beneficial effect of the structured swimming intervention on the emotional state of the participating female sport sciences students.

Contextualizing the Research

The university environment presents a unique set of challenges for young adults. Beyond the rigorous academic demands, students often grapple with significant life transitions, including establishing independence, navigating complex social dynamics, and confronting concerns about future career prospects. These factors, coupled with potential financial pressures, can contribute to elevated levels of stress, mood instability, and psychological distress. Consequently, there has been a growing imperative to identify and implement effective strategies that support the mental and emotional resilience of university populations.

Physical exercise has long been advocated as a primary, accessible, and preventive measure for enhancing mental health. Numerous studies have established a strong correlation between regular physical activity and improved mood, life satisfaction, and psychological fortitude among university students. Exercise is recognized as a potent behavioral tool that aids in stress management, mitigates symptoms of depression and anxiety, and ultimately boosts overall subjective wellbeing. While meta-analyses have consistently affirmed the positive impact of exercise-based interventions on mental health indicators in this demographic, a key question remains: which specific types of exercise are most effective for particular psychological outcomes?

The Promise of Aquatic Exercise

In this context, water-based exercises, and swimming in particular, have garnered increasing attention due to their distinct physiological and psychological characteristics. Swimming, as a full-body activity, places minimal stress on the joints, making it a sustainable and accessible option for a wide range of individuals. The inherent buoyancy of water can reduce the perceived exertion during exercise, potentially enhancing adherence to training regimens. Furthermore, the rhythmic breathing patterns and repetitive movements characteristic of swimming may contribute to a more balanced emotional response and a sense of calm.

Existing research on aquatic exercise and mental health suggests that these activities can positively influence mood and reduce anxiety symptoms. A systematic review indicated that aquatic exercise significantly improves mental health outcomes, especially when performed at light to moderate intensities. Studies specifically involving university students have also pointed to the potential of swimming training to ameliorate negative emotional states. Beyond the direct physiological benefits of exercise, the broader psychological impact of "blue spaces"—environments that include water bodies—has been documented, with these settings often associated with calming and restorative effects that enhance psychological wellbeing. Research on open-water swimming, for instance, has reported reductions in perceived stress and improvements in mental wellbeing.

Focus on Sport Sciences Students

The cohort of students enrolled in faculties of sport sciences presents a particularly compelling group for investigating these effects. While these students generally maintain more physically active lifestyles, they are not immune to psychological stressors. Performance expectations, the intensity of practical coursework, and anxieties about future professional careers can all contribute to significant psychological strain. Moreover, a positive disposition towards exercise does not automatically translate into spontaneous emotional improvement. Therefore, examining the impact of a structured exercise program like swimming within an experimental framework, as done in this study, offers valuable scientific and practical insights.

Despite the promising general findings regarding the psychological benefits of aquatic exercise, intervention studies with university students that employ clearly defined durations and robust experimental-control designs remain relatively scarce. Variations in measurement tools and intervention protocols further complicate the generalization of existing results. Hence, evaluating the effects of a structured swimming exercise program implemented over a defined period, such as the 10-week duration in this study, is crucial for addressing this gap in the literature.

Methodological Rigor

The study’s design ensured a high level of scientific validity. The pretest-posttest control group structure allowed for a direct comparison of changes within each group over time and between the groups themselves. This enabled the researchers to isolate the effects attributable to the swimming intervention.

The recruitment process targeted female undergraduate students aged 18-22 years within the Faculty of Sport Sciences at Aksaray University. Participants were carefully screened to ensure they met specific inclusion and exclusion criteria, which included age range, enrollment status, absence of chronic health conditions, and not currently using psychotropic medication. The sample size of 42 (21 per group) was deemed adequate based on power calculations, with an additional buffer to account for potential attrition.

Random assignment to the intervention or control group was performed using a computer-generated random number sequence, managed by an independent researcher to maintain allocation concealment. While blinding of participants and the supervising instructor was not feasible due to the nature of the intervention, researchers took steps to minimize procedural bias by standardizing questionnaire administration conditions.

The 10-week swimming protocol was meticulously designed, incorporating progressive overload principles. Sessions, held twice weekly, included standardized warm-up and cool-down periods, with the main swimming exercise duration gradually increasing and intensity escalating from low-to-moderate in the initial weeks to moderate-to-high in the later stages. Intensity was monitored using the Borg Rating of Perceived Exertion (RPE) scale.

Data Collection and Analysis

Emotional status was assessed using the validated Beck Hopelessness Scale (BHS) and the Oxford Happiness Questionnaire—Short Form (OHQ-SF). The BHS, a 20-item scale, measures negative future expectations, while the OHQ-SF, an 8-item scale, assesses overall happiness. Both instruments have established validity and reliability in Turkish, ensuring appropriate measurement for the study population.

Statistical analyses were conducted using IBM SPSS Statistics. Independent samples t-tests were used to confirm baseline comparability between the groups, while a 2×2 mixed-design repeated measures ANOVA was employed to analyze the effects of time and group on hopelessness and happiness scores. Effect sizes were calculated using partial eta squared (η²p) to quantify the magnitude of the observed effects.

Ethical approval was secured from the Ethics Committee of Aksaray University, and all participants provided written informed consent, assuring them of their right to withdraw at any time without penalty. Confidentiality was maintained throughout the study.

Broader Implications and Limitations

The findings of this study carry several important implications. Firstly, the positive impact of a structured swimming program on emotional wellbeing was observed even within a population generally considered to be physically active and exercise-aware. This suggests that the specific attributes of a well-designed, supervised, and progressive aquatic exercise program—beyond mere participation in physical activity—can offer significant psychological benefits. The restorative properties of the aquatic environment itself may also play a crucial role.

However, the study’s conclusions must be interpreted within its specific context. The sample’s homogeneity, comprising only female sport sciences students, limits the generalizability of the findings to the broader university student population, which includes diverse academic disciplines, genders, and varying levels of physical activity. The reliance on self-report measures for assessing emotional states also introduces a potential for response bias and expectancy effects, as participants and instructors could not be blinded to the intervention. Furthermore, the monitoring of physical activity in the control group was limited to self-report, meaning that variations in their habitual activity levels could not be fully accounted for. The absence of long-term follow-up data also prevents conclusions about the durability of the observed emotional improvements.

Future Directions

To build upon these findings and enhance their applicability, future research should aim to include more diverse university populations, encompassing a wider range of academic disciplines, genders, and baseline physical activity levels. Incorporating objective measures of physical activity, such as accelerometers or activity logs, would strengthen the control group comparisons. Longitudinal studies with extended follow-up periods are essential to determine the long-term sustainability of the emotional benefits. Comparative studies investigating the differential effects of aquatic versus land-based exercise modalities would also provide valuable insights into the unique contributions of swimming to university students’ emotional wellbeing.

Conclusion

In conclusion, this 10-week structured swimming exercise program demonstrated a significant positive impact on the emotional wellbeing of female sport sciences students. The observed reductions in hopelessness and increases in happiness, supported by moderate to large effect sizes, suggest that swimming can be a valuable supportive intervention for this specific university subgroup. Nevertheless, the findings should be considered within the limitations of the study, particularly regarding sample homogeneity and measurement methods. While swimming emerges as a promising modality for enhancing emotional health in physically active university students, further research with broader populations and more robust methodologies is warranted to solidify these conclusions and inform wider public health recommendations.
