Effect of swimming exercise program on quality of life in patients with diabetic foot ulcer

This research aimed to examine the effect of a swimming exercise program on the quality of life in patients with diabetic foot ulcers (DFUs). DFUs are a common complication of diabetes that significantly impact patients' physical and psychological well-being and impose a substantial burden on healthcare systems. Physical activity, including swimming, has been shown to improve various aspects of health and well-being. However, its specific effects on the quality of life in patients with DFUs have not been extensively studied. The study included twenty patients diagnosed with DFUs who volunteered to participate in a 12-week swimming exercise program. The program consisted of three one-hour sessions per week, with exercises performed in an indoor swimming pool. Participants' quality of life was assessed using the Diabetic Foot Ulcer Scale Short Form (DFS-SF) before the program and at 4, 8, and 12 weeks into the program. The results demonstrated significant improvements in various domains of quality of life among participants. The leisure, physical health, dependence/daily life, negative emotions, worry about ulcers/feet, and bothered by ulcer care domains all showed positive changes, with reduced scores on negative items and increased scores on positive items over time. These findings highlight the potential benefits of swimming as a therapeutic intervention for improving the quality of life in patients with DFUs. Swimming, as a low-impact aerobic exercise, offers physiological and psychological advantages, including fat burning, mood improvement, stress reduction, and enhanced cognitive function. The study suggests that incorporating swimming exercise programs into the management and treatment of DFUs may lead to improved overall well-being and quality of life for these patients. Further research and larger-scale studies are necessary to validate these findings and explore the long-term effects of swimming exercise programs on the quality of life in patients with DFUs. Nevertheless, this research provides valuable insights for healthcare professionals in developing comprehensive treatment approaches for individuals with DFUs.

Effects of Exercise Training and L-Arginine Loaded Chitosan Nanoparticles on Hippocampus Histopathology, β-Secretase Enzyme Function, APP, Tau, Iba1and APOE-4 mRNA in Aging Rats.

The objective of this study was to evaluate the combined and independent effects of exercise training and L-Arginine loaded chitosan nanoparticles (LA CNPs) supplementation on hippocampal Tau, App, Iba1, and ApoE gene expression, oxidative stress, β-secretase enzyme activity, and hippocampus histopathology in aging rats. Thirty-five male Wistar rats were randomly assigned to five groups (n = 7 in each): Young (8 weeks old), Old (20 months old), old + L-arginine supplementation (Old Sup), old + exercise (Old Exe) and old + L-arginine supplementation + exercise (Old Sup + Exe). LA CNPs were administered to the supplement groups through gavage at a dosage of 500mg/kg/day for 6-weeks. Exercise groups were subjected to a swimming exercise program five days/week for the same duration. Upon the completion of their interventions, the animals underwent behavioral and open-field task tests and were subsequently sacrificed for hippocampus genetic and histopathological evaluation. For histopathological analysis of brain, Cresyl violet staining was used. Congo Red staining was employed to confirm amyloid plaques in the hippocampus. Expressions of Tau, App, Iba1, and ApoE genes were determined by real-time PCR. In contrast to the Old group, Old Exe and Old Sup + Exe groups spent more time in the central space in the open field task (p < 0.05) and have more live cells in the hippocampus. Old rats (Old, Old Sup and Old Exe groups) exhibited a significant Aβ peptide accumulation and increases in APP, Tau, Iba1, APOE-4 mRNA and MDA, along with decreases in SOD compared to the young group (p < 0.05). However, LA CNPs supplementation, exercise, and their combination (Old Sup, Old Exe and Old Sup + Exe) significantly reduced MDA, Aβ plaque as well as APP, Tau, Iba1, and APOE-4 mRNA compared to the Old group (p < 0.05). Consequently, the administration of LA CNPs supplements and exercise might regulate the risk factors of hippocampus cell and tissue.

Respiratory function rehabilitation in individuals with Covid-19: swimming exercise

Background and Study Aim. Understanding the impact of swimming exercises on post-Covid-19 respiratory function is crucial for optimizing recovery strategies in affected individuals. The aim of this study is to determine the effect of 8-week swimming exercises on respiratory function parameters in adult individuals who have had Covid-19 disease. Material and Methods. Sixteen male students, aged 19-21, voluntarily participated in the study. Eight participants were assigned to the experimental group (EG), and eight to the control group (CG), all of whom were students of the Faculty of Sports Sciences at the University. The EG underwent an 8-week swimming exercise program conducted at the Bingöl Youth and Sports swimming pool (25 meters), three days a week. The CG was not involved in any exercise regimen. Pulmonary function tests (FVC, FEV1, FEV1/FVC, PEF) were conducted using a Cosmed Pony FXdel 2016 spirometer, one day before and one day after the exercise program for both EG and CG. Data analysis was performed using Independent Samples and Paired Samples T tests in SPSS 25, with a significance level set at p &lt; 0.05. Results. A statistically significant increase in respiratory FVC, FEV1, FEV1/FVC, and PEF function values was observed in the experimental group (EG) after the exercise intervention (p &lt; 0.05). This increase was observed when comparing these values to their pre-exercise measurements. In contrast, there was no statistically significant difference in respiratory function results before and after exercise in the control group (CG) (p &gt; 0.05). Conclusions. The findings of this study highlight the therapeutic potential of an 8-week swimming exercise program in significantly enhancing respiratory function among adult individuals who have previously contracted Covid-19. These results offer valuable insights for the development of post-Covid-19 rehabilitation protocols, emphasizing the importance of regular exercise, such as swimming, in the recovery process.

Swimming exercise attenuates mechanical hypersensitivity and mitigates peripheral nerve degeneration in rats with painful diabetic neuropathy (PDN)

BackgroundThis study aimed to assess the effectiveness of swimming exercise in alleviating mechanical hypersensitivity and peripheral nerve degeneration associated with a pre-clinical model of painful diabetic neuropathy (PDN). MethodsThis study is a pre-clinical study conducted using the streptozocin (STZ)-induced PDN rat model. Rats were randomly allocated to three groups: a vehicle group of non-diabetic rats (Vehicle, n = 9), a group of rats with PDN (PDN, n = 8), and a group of rats with PDN that performed a swimming exercise program (PDN-SW, n = 10). The swimming exercise program included daily 30-minute swimming exercise, 5 days per week for 4 weeks. Von Frey testing was used to monitor hindpaw mechanical sensitivity over 4 weeks. Assessment of cutaneous peripheral nerve fiber integrity was performed after the 4-week study period via immunohistochemistry for protein gene product 9.5-positive (PGP9.5+) intra-epidermal nerve fiber density (IENFD) in hind-paw skin biopsies by a blinded investigator. ResultsThe results showed that swimming exercise mitigated but did not fully reverse mechanical hypersensitivity in rats with PDN. Immunohistochemical testing revealed that the rats in the PDN-SW group retained higher PGP9.5+ IENFD compared to the PDN group but did not reach normal levels of the Vehicle group. ConclusionsThe results of this study indicate that swimming exercise can mitigate mechanical hypersensitivity and degeneration of peripheral nerve fibers in rats with experimental PDN.

Swimming exercise and nano-l-arginine supplementation improve oxidative capacity and some autophagy-related genes in the soleus muscle of aging rats

The present research aims to evaluate the effect of swimming exercise and chitosan-coated l-arginine on mitochondrial oxidation, BCL2 Interacting Protein 3 (Bnip3), NIP-like protein × (Nix), B-cell lymphoma-extra-large (Bcl-xL) and autophagy-related protein light chain 3(LC3) expression in soleus muscle of aging rats. In this experimental research, 25 male Wistar rats were assigned into five groups randomly: young, old, old + Nano l-arginine (Nano L-a), old + exercise (Ex), and old + Nano l-arginine (Nano L-a) + exercise (Ex) (n = 5 in each). They performed a swimming exercise program five days a week for six weeks. To determine the relative strength for rats before and after performing these interventions, the 1repetition maximum (1RM) test was done as a pre and post-test. The exercise program started with 20 min and after four sessions, gradually increased to 60 min and this time was maintained until the completion of the training period. l-arginine coated with chitosan nanoparticles was given to the rats in the l-arginine-supplemented group via gavage at a dosage of 500 mg/kg/day, five days a week, for six weeks. Additionally, the rats in all groups were fed a normal diet (2.87 kcal/g and 15 % energy from fat). Upon the completion of the protocol implementation, the rats were sacrificed and the soleus muscle was fixed and frozen to determine hematoxylin and eosin (H&E) staining, immunohistochemistry (IHC), gene expression analysis, levels of reactive oxygen species (ROS), and total antioxidant capacity (TAC). The results from the present research indicated that swimming exercise and Nano l-arginine improve the strength and histology of muscle tissue in old rats (p < 0.05). Aging significantly increased the expression of Nix and Bnip3 (p < 0.05) and reduced the Bcl-xL gene expression (p < 0.05). The expression of LC3 protein also increased with aging (p < 0.05). Therapeutic interventions, such as combined treatment (old + Nano L-a + Ex) for old animals, reduced the amount of this protein in soleus muscle (p < 0.05). The ROS values also showed a significant reduction only in the old + Nano L-a + Ex group compared to the old group. Moreover, TAC values show a significant decrease in the old and old + Ex groups in comparison to the young group. The use of arginine supplement, especially in nano form, along with swimming exercise seems to reduce the oxidative damage to the elderly muscle tissue, which has a positive effect on the structure and function of the soleus muscle. Since these interventions only had a significant effect on LC3 protein, further studies with more diverse measurement methods for autophagy are suggested.

Swimming exercise with L-arginine coated nanoparticles supplementation upregulated HAND2 and TBX5 expression in the cardiomyocytes of aging male rats.

We investigated possible cardioprotective mechanisms of L-arginine coated nanoparticles (L-ACN) combined with swimming exercise (SE) in aging male rats considering heart and neural crest derivatives-expressed protein 2 (HAND2) and t-box transcription factor 5 (TBX5). Thirty-five male Wistar rats were randomly assigned into five groups: young, old, old + L-ACN, old + SE, and old + L-ACN + SE (n = 7 in each). L-arginine coated with chitosan nanoparticles was given to L-ACN groups via gavage at 500mg/kg/day. SE groups performed a swimming exercise program 5 days per week for 6 weeks. The exercise program started with 20min, gradually increasing to 60min after four sessions, which was then constant until the completion of the training period. After the protocol completion, the rats were sacrificed, and the heart was fixed and frozen to carry out histological, immunohistochemistry (IHC), and gene expression analyses. The expression of HAND2 protein, HAND2 mRNA, and TBX5 mRNA of the heart tissue was significantly higher in the young group than in all older groups (P < 0.05). The old + L-ACN, old + SE, and old + L-ACN + SE groups showed a significant increase in these factors compared to the old group (P < 0.05). Nano-L-arginine supplement, along with swimming exercises, seems to have cardioprotective potential and improve cardiac function in old age by strengthening cardiomyocyte signaling, especially HAND2 and TBX5. However, more research is required, particularly on human samples.

Casein Kinase-2 Interacting Protein-1 Regulates Physiological Cardiac Hypertrophy via Inhibition of Histone Deacetylase 4 Phosphorylation.

Different kinds of mechanical stimuli acting on the heart lead to different myocardial phenotypes. Physiological stress, such as exercise, leads to adaptive cardiac hypertrophy, which is characterized by a normal cardiac structure and improved cardiac function. Pathological stress, such as sustained cardiac pressure overload, causes maladaptive cardiac remodeling and, eventually, heart failure. Casein kinase-2 interacting protein-1 (CKIP-1) is an important regulator of pathological cardiac remodeling. However, the role of CKIP-1 in physiological cardiac hypertrophy is unknown. We subjected wild-type (WT) mice to a swimming exercise program for 21 days, which caused an increase in myocardial CKIP-1 protein and mRNA expression. We then subjected CKIP-1 knockout (KO) mice and myocardial-specific CKIP-1-overexpressing mice to the 21-day swimming exercise program. Histological and echocardiography analyses revealed that CKIP-1 KO mice underwent pathological cardiac remodeling after swimming, whereas the CKIP-1-overexpressing mice had a similar cardiac phenotype to the WT controls. Histone deacetylase 4 (HDAC4) is a key molecule in the signaling cascade associated with pathological hypertrophy; the phosphorylation levels of HDAC4 were markedly higher in CKIP-1 KO mouse hearts after the swimming exercise program. The phosphorylation levels of HDAC4 did not change after swimming in the hearts of CKIP-1-overexpressing or WT mice. Our results indicate that swimming, a mechanical stress that leads to physiological hypertrophy, triggers pathological cardiac remodeling in CKIP-1 KO mice. CKIP-1 is necessary for physiological cardiac hypertrophy in vivo, and for modulating the phosphorylation level of HDAC4 after physiological stress. Genetically engineering CKIP-1 expression affected heart health in response to exercise.

The Effect of 8-Weeks of Low-Intensity Swimming Training on Promyelocytic Leukemia Zinc Finger Protein and Spermatid Transition Nuclear Protein Gene Expression in Azoospermic Rats Model

Aims: One of the causes of infertility in men is the azoospermia disease, which is attributed to the lack of sperm in each sperm. The primary function of spermatogenesis is the maintenance, proliferation, and differentiation of spermatogonial cells. Thus, the present study aimed to investigate the changes in Promyelocytic Leukemia Zinc Finger (PLZF) and spermatid Transition Nuclear Protein (TNP) gene expression levels in an azoospermic rat model after 8 weeks of low-intensity aerobic training. Methods &amp; Materials: In this experimental study, 15 adult male Wistar rats were randomly divided into three groups of healthy control, with azoospermia, and exercise plus azoospermia after creating an azoospermia model. The patient plus exercise group performed a low-intensity swimming exercise 30 minutes a day, five days a week for 8 weeks, after the creation of the azoospermic rats. A One-way ANOVA test was used for data analysis. Findings: The results showed that a period of swimming exercise program in the exercise plus azoospermia group significantly reduced PLZF gene expression compared to the healthy control groups (P=0.001) and no significant increase to the azoospermia group (P=0.06). There was also a significant decrease in TNP gene expression levels in the exercise plus azoospermia group compared to the healthy control group (P=0.001) and a significant increase in the azoospermia group (P=0.057). Conclusion: Based on these Findings, it can be stated that the alteration of key molecules or signaling pathways and expression of the PLZF and TNP genes in the spermatogenesis process may increase infertility, but regular aerobic exercise, such as low-intensity swimming, helps to control the effects of infertility by increasing the maintenance and development of spermatogonial stem cells.

Swimming exercise decreases the absence-like epileptic activity in WAG/Rij rats

AimThe aim of the present study was to evaluate the effects of long (60 min/day), moderate (30 min/day) and short (15 min/day) term daily swimming exercise programs for 90 days on durations and the spike-wave discharges (SWDs) seen in the electrocorticographic (ECoG) recordings of WAG/Rij rats with absence epilepsy. Materials and methodsThirty-five adult male rats were divided into 5 groups as; Group 1: Control, Group 2: Sham (daily exposed to shallow water), Group 3: 15 min/day swimming exercise, Group 4: 30 min/day swimming exercise, Group 5: 60 min/day swimming exercise. After 90 days of swimming exercise program; ECoG recordings were taken for 2 h. Total number and cumulative length of SWDs in the recordings were used for evaluation of the seizures. ResultsBoth of the SWD parameters were significantly decreased in all swimming exercise groups compared to control and sham groups. The moderate swimming group (30 min/day) was found the most effective exercise program considering both of the SWD parameters of absence epilepsy. ConclusionThe results of the present study provide electrophysiologic evidence for the role of swimming exercise on the modulation of genetic absence epilepsy seizures in WAG/Rij rats.

A Qualitative Examination of a Mothers' Swim Program: What Keeps Them Coming Back and How Does it Improve Their Psychological Wellbeing?

Introduction Exercise is widely accepted as an effective activity for alleviating the impact of psychosocial challenges associated with motherhood. However our current understanding of how to help mothers adhere to exercise and how it affects positive psychosocial outcomes is lacking. Objective To examine what aspects of a mother-focused swimming exercise program that participating mothers considered most influential in supporting their continuing exercise adherence as well as positively influencing their psychological wellbeing. Methods Qualitative thematic content analysis was performed on individual interview data from mothers, with a child of five years of age or younger, who regularly participated (three or more times a fortnight for six weeks or more) in the organized group based swim programs specifically for mothers (N = 19). Results Mothers' perceptions of the factors supporting their adherence to the swim program were inherently intertwined with factors they considered positively influenced their mental health. Mothers' experiences of the swim program highlighted three higher order themes associated with supporting continued participation and positive psychological outcomes: Environmental factors; social support factors; and health promoting factors. Conclusion Environmental, social support, and health promoting factors are important factors in affecting the efficacy of mothers' exercise programs to enhance participation and wellbeing.

Effects of swimming exercise on high-fat diet-induced low bone mineral density and trabecular bone microstructure in rats

[Purpose] This study aimed to investigate the effect of swimming exercise on high-fat diet-induced low bone mineral density (BMD) and trabecular bone microstructure in rats. [Methods] Eight-week-old male Sprague- Dawley (SD) rats were divided into a normal diet group (n = 9) and a high-fat diet group (n = 15). Three rats in each group were sacrificed after 8 weeks of high-fat diet to evaluate the association between high-fat diet and bone health. The other 18 rats were reassigned to 3 groups (normal diet control, NC; high-fat diet control, HC; high-fat diet + Exercise, HEx) for up to another 8 weeks. Rats in the exercise group were trained for a swimming exercise program (1 h/day, 5 times/ week for 8 weeks). All rats were sacrificed 24 h after the last bout of exercise to analyze the BMD and trabecular bone microstructure in the femur and tibia, using micro-computed tomography. [Results] First, the effect of high-fat diet on bone health was examined. It was observed that BMD, percent bone volume (BV/TV), and trabecular number (Tb.N) of the femur and tibia were lower in rats in the high-fat diet group than in those in the normal diet group (p < .05). In addition, BMD, BV/TV, and Tb.N of the femur and tibia were significantly increased in rats that underwent the 8-week swimming exercise program, compared to the corresponding values in rats in the HC group (p < .05). [Conclusion] These results indicate that high-fat diets negatively affect bone health; however, these negative effects can be improved by exercises such as swimming.

Examination of Swimming Exercises' Effects on Disabled Individuals' Life Satisfaction Levels

This research was done to determine how disabled individuals’, who were let doing swimming exercise, life satisfactions get shaped depend on gender, age and obstacle situation variance. With this aim there were 24 female and 26 male, whose ages differ 16 and 21 ± 3, 54 totally 50 people were included to the study. For the research permission was taken from both participants and their families that they were volunteers for it. To the participants there was 6 weeks swimming exercise program (3 days in a week for one hour) applied. In the beginning and the end of the program as pretest and posttest for determining the participants’ life satisfaction levels the Life Satisfaction Scale Form was applied. In the result of the research while there was not any statistically difference observed (p>0,05) in the disabled individuals’ life satisfaction levels depend on age, there was a statistically meaningful difference determined in the life satisfaction levels of disabled individuals (p<0,05). According to this it can be sad that swimming exercises is a positive activity that positively affects especially ladies’ life satisfaction levels.

Swimming exercise ameliorates neurocognitive impairment induced by neonatal exposure to isoflurane and enhances hippocampal histone acetylation in mice

Isoflurane-induced neurocognitive impairment in the developing rodent brain is well documented, and regular physical exercise has been demonstrated to be a viable intervention for some types of neurocognitive impairment. This study was designed to investigate the potential protective effect of swimming exercise on both neurocognitive impairment caused by repeated neonatal exposure to isoflurane and the underlying molecular mechanism. Mice received 0.75% isoflurane exposures for 4h on postnatal days 7, 8, and 9. From the third month after anesthesia, the mice were subjected to regular swimming exercise for 4weeks, followed by a contextual fear condition (CFC) trial. We found that repeated neonatal exposure to isoflurane reduced freezing behavior during CFC testing and deregulated hippocampal histone H4K12 acetylation. Conversely, mice subjected to regular swimming exercise showed enhanced hippocampal H3K9, H4K5, and H4K12 acetylation levels, increased numbers of c-Fos-positive cells 1h after CFC training, and less isoflurane-induced memory impairment. We also observed increases in histone acetylation and of cAMP-response element-binding protein (CREB)-binding protein (CBP) during the swimming exercise program. The results suggest that neonatal isoflurane exposure-induced memory impairment was associated with dysregulation of H4K12 acetylation, which may lead to less hippocampal activation following learning tasks. Swimming exercise was associated with enhanced hippocampal histone acetylation and CBP expression. Exercise most likely ameliorated isoflurane-induced memory impairment by enhancing hippocampal histone acetylation and activating more neuron cells during memory formation.

The Effect of Swimming Exercise on Motor Development Level in Adolescents with Intellectual Disabilities

Objectives: In this study, it was aimed to analyze the effect of swimming exercise on motor development level in adolescents with intellectual disabilities. Methods: A total of 30 mild intellectual disability (MID) individuals between 15-18 age groups participated the study. Bruininks–Oseretsky Test of Motor Proficiency-Second Edition (BOT-2)- Short Form were performed to determine basic motor characteristics of children. BOT-2-Short Form was applied to the participants before and after the ten-month swimming exercise program (60 dk/ 3 days /10 week). Results: According to research findings, in terms of body weight, manual dexterity, speed and agility, upper limb coordination, and BOT-2 total point parameters, there was no statistically significant difference found between groups, measurements (pre-test and post-test), groups and their measurements (p>0.05). In terms of fine motor precision, and fine motor integration parameters, while there was no statistically significant difference found between groups (p>0.05); a significant statistical difference was found between measurements (pre-test and post-test), groups and their measurements (p 0.05); a significant statistical difference was found between groups (p 0.05); statistically significant difference was found between measurements (pre-test and post-test) (p<0.05). Conclusion: Consequently, regularly applied exercise programmes improve life quality level of individuals with MID by contributing to their motor development level.

Thoracic aorta vasoreactivity in rats under exhaustive exercise: effects of Lycium barbarum polysaccharides supplementation

BackgroundReduced arterial compliance is associated with an increased rate of morbidity and mortality in cardiovascular disease. Exercise is beneficial for compromised arterial compliance. However, the beneficial effects of exercise are lost with exhaustion. Lycium barbarum L. has been used in China for centuries to maintain good health. In this regard, the primary purpose of this study was to characterize the effects of the polysaccharides from Lycium barbarum (LBPs) on arterial compliance during exhaustive exercise.MethodsA four-week swimming exercise program was designed for rats, and the blood levels of malondialdehyde (MDA), super oxide dismutase (SOD), nitric oxide(NO) and heat shock protein 70(HSP70) were detected. The tension of aorta rings was measured to evaluate the response of rats on noradrenaline (NA)-induced contractions.ResultsThe rats administered LBPs showed longer swimming time until exhaustion than the control group of rats. Exercise-induced MDA elevation was repressed by LBPs supplementation. The LBPs-supplemented rats displayed a significant increase of SOD, NO, HSP70 than the non-supplemented rats. Additionally, LBPs significantly up-regulated the expression of eNOS and improved the endothelium-dependent vasodilatation of the aorta ring.ConclusionOur study proved that LBPs administration significantly inhibited the oxidative stress, and improved the arterial compliance.
