Aquatic Exercise and Mental Health: A Scoping Review

Identifying the benefits of recovery programs of aquatic gymnastics, aquatic ludotherapy and therapeutic swimming on human motor, kinetotherapeutic and mental capacity

Introduction

This study aimed to evaluate the motor, kinetotherapeutic, and psychological benefits of three aquatic therapeutic programs-aquagym recovery (AG), aquatic ludotherapy (ALT), and therapeutic swimming (TS)-for students specializing in balneo-physio-kinetotherapy.

Methods

The study group consisted of 101 students, out of which 43 students from the balneo-physiokinetotherapy study program (BFKT) and 67 master's degree students from physical therapy and functional rehabilitation (PTFR). The questionnaire was named Questionnaire regarding the benefits of therapeutic aquatic programs (QBTAP), and included 3 subscales according to the typology of the targeted objectives, namely: motor, kinetotherapeutic and psychological. The items of each subscale correspond to the objectives identified in the content of the 3 aquatic programs stipulated in the content of the courses corresponding to the disciplines in the education plans of academic study programs (BFK, TRFR). The motor subscale included 8 items, the kinetotherapeutic subscale included 16 items, and the psychological subscale included 10 items. The evaluation of the QBTAP questionnaire 5-point Likert scale. The three evaluated programs were: recovery aquagym (AG), aquatic ludotherapy (ALT) and therapeutic swimming (TS).

Results

The results and conclusion sections should highlight the main findings succinctly. For example: "The QBTAP showed high internal consistency (Cronbach's Alpha >0.9) across all subscales and programs, with significant differences identified between the three programs (p < 0.05).

Conclusion

The study concludes that aquagym most effectively improves motor capacity, aquatic ludotherapy enhances psychological function, and therapeutic swimming is most beneficial for recovery and rehabilitation.

High-intensity interval training vs. yoga in improving binge eating and physical fitness in inactive young females

Yoga is effective in binge eating disorder (BED) treatment, but it does not seem effective enough to improve low physical fitness. In contrast, high-intensity interval training (HIIT) is effective in improving physical fitness but has never been studied in the context of BED. In the study, 47 young inactive females with mild to moderate BED were recruited and randomly assigned to a HIIT group (HIIT), a Yoga group (YG), or a control group (CG; age, 19.47 ± 0.74, 19.69 ± 0.874, and 19.44 ± 0.63 years; BMI, 21.07 ± 1.66, 21.95 ± 2.67, and 20.68 ± 2.61 kg/m2, respectively). The intervention groups participated in 8-week specific exercises, while the CG maintained their usual daily activity. Before and after the training, participants were evaluated for BED using the binge eating scale (BES) and for physical fitness. The obtained data were compared within groups and between groups, and a correlation analysis between BES and physical fitness parameters was performed. After the training, the YG presented significant improvements in BES (- 20.25%, p = 0.006, ηp2 = 0.408), fat mass (FM, - 3.13%, p = 0.033, ηp2 = 0.269), and maximal oxygen consumption (VO2max, 11.51%, p = 0.000, ηp2 = 0.601), whereas the HIIT showed significant improvements in body weight (BW, - 1.78%, p = 0.006, ηp2 = 0.433), FM (- 3.94%, p = 0.033, ηp2 = 0.285), and BMI (- 1.80%, p = 0.006, ηp2 = 0.428), but not in BES. Comparisons between groups revealed that both HIIT and YG had significantly higher VO2max levels than CG (HIIT 12.82%, p = 0.006, ηp2 = 0.088; YG: 11.90%, p = 0.009, ηp2 = 0.088) with no difference between HIIT and YG. Additionally, YG presented significantly lower BES than both HIIT (15.45%, p = 0.02, ηp2 = 0.03) and CG (11.91%, p = 0.022, ηp2 = 0.03). In conclusion, Yoga is an effective treatment for BED, but HIIT is not, despite its high efficacy in improving physical fitness.

A Controlled Clinical Trial on the Effects of Aquatic Exercise on Cognitive Functions in Community-Dwelling Older Adults

Several therapies have been developed to reduce cognitive decline associated with aging. Aquatic exercises, which are widely used to enhance functional capacity, may play a role in stimulating cognitive functions. This study investigated the effects of a 3-month aquatic exercise program on cognitive functions in community-dwelling older adults. In this prospective, single-blinded, controlled clinical trial, 31 participants were allocated to either the experimental (aquatic exercises) or control (no-exercise) group. The intervention program consisted of exercises conducted twice a week in a 1.2 m deep indoor pool. The main outcome measures were cognitive functions, assessed using Raven's Progressive Matrices test and the Wisconsin Card Sorting Test. A repeated-measures analysis of variance was used to assess the impact of the exercise program. The effect sizes (η2p) were reported when a level of significance was achieved (p < 0.05). Compared with the control group, the participants who underwent aquatic exercises showed positive outcomes in Raven's Progressive Matrices test (p = 0.046; η2p = 0.131) and the Wisconsin Card Sorting Test (p = 0.001, η2p = 0.589). Complementary analyses of the Wisconsin Card Sorting Test indicated that the benefits of the aquatic exercise were observed in terms of the number of trials (p = 0.001, η2p = 0.478), number of errors (p = 0.001, η2p = 0.458), and number of non-perseverative errors (p = 0.001, η2p = 0.302). The results indicate that a period of three months of aquatic exercise was beneficial for stimulating specific aspects of the cognitive function of community-dwelling older individuals. Aquatic exercise should be prescribed to this population.

Effects of physical fitness on mental health of Chinese college students: across-sectional study

BACKGROUND

The physical and mental health of college students is often mentioned, but there is limited research on a direct relationship between the mental health status of college students and their physical fitness level. This study mainly proves the relationship between Chinese college students' mental health and physical fitness indicators.

METHOD

This study collected SCL-90 Scale test results from 5262 students (4012 boys and 1250 girls) through a questionnaire survey and conducted a Sport Quality Test on these students. Statistical software SPSS was applied for differential analysis and logistic regression analysis. Specifically, the differences in sport quality indicators between normal and abnormal mean total scores of psychological tests were analyzed first. Then, the binary logistic regression model was used to explore the impacts of sports quality indicator scores on students' psychological fitness.

RESULTS

There are differences in the results of physical fitness tests between students with abnormal psychology and students with normal psychology. The four indexes of students' vital capacity, speed, explosive power of lower limbs, and endurance running are effective in improving students' psychologically abnormal state, and endurance running and improving vital capacity are the most effective methods to improve students' psychologically abnormal state. In the physical tests of Chinese college students, the risk of psychological abnormalities was reduced by 9% for every one-point increase in lung capacity and 10.4% for every one-point increase in endurance running performance.

CONCLUSIONS

Chinese college students' physical fitness and mental health are related. The best methods for treating psychological disorders are lung capacity improvement and endurance running. According to the physical test results of Chinese college students, for every 1-point increase in lung capacity and endurance running, the risk of psychological abnormalities decreased by 9% and 10.4%, respectively.

How do women feel cold water swimming affects their menstrual and perimenopausal symptoms?

OBJECTIVE

This study aimed to determine how women felt cold water swimming affected their menstrual and perimenopausal symptoms.

STUDY DESIGN

An online survey that asked women who regularly swim in cold water about their experiences. The survey was advertised for 2 months on social media. Questions related to cold water swimming habits and menstrual and perimenopausal symptoms were analysed.

MAIN OUTCOME MEASURES

Quantitative and qualitative data including; frequency of menstrual and menopause symptoms, the effect of cold water swimming on these symptoms.

RESULTS

1114 women completed the survey. Women reported that cold water swimming reduced their menstrual symptoms, notably psychological symptoms such as anxiety (46.7%), mood swings (37.7%) and irritability (37.6%). Perimenopausal women reported a significant improvement in anxiety (46.9%), mood swings (34.5%), low mood (31.1%) and hot flushes (30.3%). The majority of women with symptoms swam specifically to reduce these symptoms (56.4% for period and 63.3% for perimenopause symptoms). Women said they felt it was the physical and mental effects of the cold water that helped their symptoms. For the free text question, five themes were identified: the calming and mood-boosting effect of the water, companionship and community, period improvements, an improvement in hot flushes and an overall health improvement.

CONCLUSION

Women felt that cold water swimming had a positive overall effect on menstrual and perimenopause symptoms. Studies on other forms of exercise to relieve menstrual and perimenopause symptoms may show similar findings.

Reducing sugar intake through chronic swimming training: Exploring palatability changes and central vasopressin mechanisms

Excessive sugar intake has been associated with the onset of several non-communicable chronic diseases seen in humans. Physical activity could affect sweet taste perception which may affect sugar intake. Therefore, it was investigated the chronic effects of swimming training on sucrose intake/preference, reactivity to sucrose taste, self-care in neurobehavioral stress, and the possible involvement of the vasopressin type V1 receptor in sucrose solution intake. Male Wistar rats, of from different cohorts were used, subjected to a sedentary lifestyle (SED) or swimming training (TR - 1 h/day, 5×/week, for 8 weeks, with no added load). Weekly intake was verified in SED and TR rats after access to a sucrose solution 1×/week, 2 h/day, for eight weeks. Chronic effects of swimming and/or a sedentary lifestyle were carried out three days after the end of the physical exercise protocol. Swimming training reduced the intake of sucrose solution from the third week onwards in the two-bottle test measured once a week for 8 weeks. After the ending of the swimming protocol, sucrose intake was also reduced as per its preference. This reduced intake is probably correlated with the carbohydrate aspect of sucrose since saccharin intake was not affected. In addition, chronic swimming training was shown to reduce ingestive responses, increase neutral responses, without interfering with aversive, in the sucrose solution taste reactivity test. In addition, these results are not related to a depressive-like behavior, nor to neurobehavioral stress. Furthermore, treatment with vasopressin V1 receptor antagonist abolished the reduced sucrose intake in trained rats. The results suggest that swimming performed chronically is capable of reducing intake and preference for sucrose by decreasing the palatability of sucrose without causing depressive-type behavior or stress. In addition, the results also suggest that central V1 vasopressin receptors are part of the mechanisms activated to reduce sucrose intake in trained rats.

The Long-Term Adaptations of a Combined Swimming and Aquatic Therapy Intervention in an Adult Person with High-Functioning Autism (Asperger's Syndrome): A Case Study

Individuals with High-Functioning Autism present impairments in communication, social interaction, and motor development. A low level of motor skills, namely difficulties in gross and fine mobility, and in motor control, discourage individuals with High-Functioning Autism from being involved in physical activities, resulting in fewer opportunities for social interaction. There is not much evidence available about the effects of regular swimming exercise and/or aquatic therapy on health promotion in adults with High-Functioning Autism. An adult male (22 yrs) diagnosed with High-Functioning Autism participated in a combined 6-month swimming and aquatic therapy program (two sessions/week, 60 min each). The pre- and post-intervention assessments consisted of physical fitness, balance, functional ability, and psychomotor tests. The post-intervention assessments showed improvements in the standing long jump (+100%), hand grip force (+71.7%), bend arm hang test (+123.1%), and the physiological parameters in the 6 min walk test (+10.2%). On the opposite, decrements in the sit-up (-12%) and sit-and-reach test (-6.3%) were observed. It was noted that the participant frequently lost interest and focus quickly, resulting in the abandonment of the exercise. Conclusively, there is a great need for further research on this topic examining a larger adult population.

Blue prescription: A pilot study of health benefits for oncological patients of a short program of activities involving the sea

Performing outdoor activities in blue spaces can help improve human health and mental well-being by reducing stress and promoting social relationships. The number of people surviving cancer has increased globally to experience this disease as a life-changing and chronic condition with physical and psychosocial symptoms that have negative impacts on their quality of life. While there has been a growth of programs in green spaces to meet the needs of cancer patients, such as follow-up post-treatment care, support groups and physical activity programs, very few studies have examined the effects of activities involving the sea for the health and well-being of oncology patients. This is the first study to evaluate whether different outdoor activities in blue spaces can benefit oncological patients' physical and mental health using smartwatches, sphygmomanometers and Profile of Mood States (POMS) questionnaires. We assessed changes in blood pressure, heart rate, sleep quality and mental health of 16 patients after twelve sessions of three different activities (walking, beach and snorkelling) and four sessions of a control activity. While no significant differences between activities were observed in terms of the data gathered by the smartwatches, a gradient of positive results for human mental health was observed towards exposure to a blue space, assessed through POMS questionnaires. Results show that exposure to blue spaces contributes to tension and anger reduction and improves the vigour mood state of oncology patients. No significant increases in patients' heart rate were recorded after the beach and snorkelling activities, with results similar to the control activity, suggesting that the contribution may be to participants' relaxation.

The effects of water-based exercise on body composition: A systematic review and meta-analysis

AIMS

This study aimed to investigate the effects of water-based exercise (WBE) on body composition.

METHODS

Trials published up to October 28, 2022 were searched using the PubMed, EMBASE, Web of Science, Cochrane, Scopus, and Ovid databases. Randomized controlled trials of healthy adults published in English, comparing WBE and control groups, were included. Other studies with different research designs and participants with medical diagnoses were excluded. The main outcome measures were body weight (BW), body fat mass (BFM), body fat percentage (BFP), lean mass (LM), and skeletal muscle mass (SMM).

RESULTS

Overall, 17,458 potential studies were identified. After a closer inspection, 79 full-length articles were considered for further screening. Finally, 20 studies, involving 565 participants, were included in the meta-analysis. The WBE was beneficial in reducing BW, BFM, and BFP and increasing LM and SMM. Subgroup analyses were conducted based on different exercise intensities and times per week. Moderate- or moderate-vigorous-intensity exercise helped improve body composition, while lower-intensity WBE or aquatic high-intensity interval training (HIIT) seemed less helpful. Training for <120 min/week was insufficient to improve body composition. Training for >120 min/week was associated with improvements in body composition.

CONCLUSIONS

Moderate- or moderate-vigorous-intensity WBE helps improve body composition. Adults are encouraged to exercise for >120 min/week.

Applying Gamification Principles and Therapeutic Movement Sequences to Design an Interactive Physical Activity Game: Development Study

BACKGROUND

Depression is a severe illness that has accelerated with the spread of COVID-19 and associated lockdowns. As a result, reported physical activity has substantially decreased, further increasing depressive symptoms.

OBJECTIVE

This study aims to explain the use of gamification principles to develop content for an interactive physical activity game for depression based on clinically proven depression diagnostic criteria.

METHODS

We discuss related work in this field, the game design framework, the users' depression severity, how we customize the contents accordingly, the gradual progression of the game to match exercise principles, and user flow optimization.

RESULTS

We provide a brief description of each of the games developed, including instructions on how to play and design aspects for flow, audio, and visual feedback methods. Exergames (interactive physical activity-based games) stimulate certain physical fitness factors such as improving reaction time, endurance, cardiovascular fitness, and flexibility. In addition, the game difficulty progresses based on various factors, such as the user's performance for successful completion, reaction time, movement speed, and stimulated larger joint range of motions. Cognitive aspects are included, as the user has to memorize particular movement sequences.

CONCLUSIONS

Mental health issues are linked to behavior and movement; therefore, future physical activity-based interactive games may provide excellent stimulation for inducing user flow, while physical activity can help train various physical fitness factors linked to depression.
