Yayın Acute effect of dual-task endurance exercise on cognitive functions and myocardial oxygen consumption; a randomized, controlled trial(Routledge, 2025) Atak, Ebrar; Ataç, AmineDual-task exercise and its impacts on cognitive function have gained increasing attention in recent years. Targeted aerobic exercise, cardiovascular responses, and the associated improvements in cognitive performance appear promising for mitigating certain cognitive disorders, although the optimal protocol remains unclear. In this randomized controlled trial, 34 participants meeting inclusion criteria were allocated into either a standardized aerobic exercise group (BSAEgr, n = 18) or a dual-task aerobic exercise group (BIDAgr, n = 16). Cognitive status was assessed with the Montreal Cognitive Function Assessment Scale (MOCA), and reaction time performance was measured using the Nelson Reaction Test (NRT). Cardiovascular responses including systolic blood pressure, diastolic blood pressure, pulse rate, and the double product formula were evaluated before and after the intervention. The findings demonstrated that dual-task aerobic exercise led to greater improvements in cognitive function compared to standardized aerobic exercise. Significant improvements were observed in MOCA scores, NRT distance, and NRT outcome measures within the dual-task group (p < 0.005). These results provide preliminary evidence that incorporating dual-task elements into aerobic training may enhance both cognitive and cardiovascular outcomes, suggesting potential applicability in preventive and rehabilitative settings.Yayın Correction: the effect of stretching exercises applied to caregivers of children with development disabilities on musculoskeletal muscle mobility and respiratory function (International Journal of Environmental Research and Public Health, (2024), 21, 10, (1361), 10.3390/ijerph21101361)(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Ataç, Amine; Atak, EbrarIn the original first publication [1], the general information language in the second and third paragraphs of the Introduction section was revised and the expressions in the paragraphs were rearranged because of the coincidental similarity with the publication in the newly added Reference [17]. With this correction, the order of some references has been adjusted accordingly. The revised paragraphs and the newly added reference are shown below. Adequate hamstring extensibility plays a critical role in enabling functional movement patterns required in everyday life. However, reduced hamstring length is frequently observed in the general population, which may be explained by the muscle’s involvement in sustained postural control and its tendency to remain in a shortened state during prolonged static positions [9,10]. Shortening of the hamstring muscle can alter pelvic alignment by promoting posterior pelvic tilt, which subsequently affects spinal curvatures and pathologies, including a reduction in lumbar lordosis and an increase in thoracic kyphosis. These postural alterations may restrict thoracic mobility, influence diaphragmatic mechanics, and negatively impact respiratory efficiency. Furthermore, hamstring tightness may contribute to dysfunction not only locally but also across anatomically distant segments within the posterior kinetic chain [9,11–14]. The posterior kinetic chain comprises multiple muscle groups, including the spinal extensors, gluteus maximus, hamstring muscles, calf musculature such as the gastrocnemius and soleus, as well as intrinsic muscles of the foot [15]. Muscles forming the posterior chain function collectively to maintain upright posture against gravitational forces. Increased tension in any component of this chain, such as the hamstring muscle, may be transmitted to other interconnected structures. This phenomenon is consistent with the biological tensegrity model, which proposes that bodily tissues operate as an integrated system balancing tensile and compressive forces throughout the body [16–18]. Increased stiffness and reduced flexibility in the hamstring muscles are frequently accompanied by compensatory tension in proximal regions, particularly within the lumbar and shoulder musculature [14]. In the literature, there are studies explaining the relationship between hamstring muscles and respiratory parameters with the myofascial theory [9,16]. According to this theory, the human body is composed of fascia, a single tissue that functions as interconnected chains. Tension in one point of the fascia, which shows integrity, can result in tension or restriction in another part of the body [18]. Previous research has explored the association between hamstring muscle characteristics and respiratory parameters within the framework of myofascial continuity. According to this perspective, fascia functions as a unified connective network, allowing mechanical tension generated in one region to influence distant anatomical areas. In this context, alterations in diaphragmatic mobility or tension may contribute to functional limitations observed during the assessment of hamstring flexibility [15–17]. Bırık, B.

Cognition and cardiorespiratory responses are closely interlinked, necessitating further investigation into their dynamics. The potential benefits of combining motor imagery (MI) and action observation (AO) based breathing exercises in rehabilitation have not been fully explored. This study was aimed at assessing the acute effects of MI combined with AO on cognitive function and cardiorespiratory responses. Thirty-three healthy adults were randomized into MI combined with AO breathing (MI+AO), active respiratory exercise (ARE), and control groups, with equal distribution across groups. Electroencephalography (EEG) data were collected using a Muse EEG headband, and cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) while imagining activities were measured via the Kinesthetic and Visual Imagery Questionnaire (KVIQ). Significant improvements in the Timed Up and Go (TUG) test and systolic blood pressure were observed in the ARE group (p < 0.05), alongside improvements in MoCA and KVIQ scores (p < 0.05). EEG data revealed significant decreases in delta and theta power at the temporoparietal (TP) location in the ARE group (p < 0.05). These findings suggest that MI and AO, when combined with respiratory exercises, may serve as effective passive strategies to support cognition and cardiorespiratory function, particularly in individuals who struggle to actively participate in pulmonary rehabilitation.Yayın The effect of stretching exercises applied to caregivers of children with development disabilities on musculoskeletal muscle mobility and respiratory function(Multidisciplinary Digital Publishing Institute (MDPI), 2024) Ataç, Amine; Atak, EbrarWe aimed to investigate the effect of stretching exercises applied to the hamstring, one of the posterior muscle chains, on musculoskeletal flexibility, chest mobility, and respiratory function. Proprioceptive neuromuscular facilitation and static stretching exercises were applied to 30 healthcare personnel caring for children with developmental delays using a crossover randomized study design. Posterior muscle chain mobility was assessed using the popliteal angle test (PAT) for the hamstring muscle, the mobility of the lumbar muscles was assessed using the Schober test (ST), and the mobility of the posterior chain muscles as a whole was assessed using the finger-to-floor distance test. Chest mobility was measured using chest circumference measurements and lung volumes were measured using the pulmonary function test (PFT). The results showed that stretching exercises applied to the hamstrings led to significant improvements in PAT, ST, and chest mobility in the direction of maximal expiration (p < 0.05), without being superior to each other. Ten males (33.3%) and twenty females (66.7%) who met the inclusion criteria were analyzed. The mean age of the participants was 26.6 ± 5.9 years, the mean height was 169.53 ± 8.67 cm, the mean weight was 65.26 ± 12.03 kg, and the mean body mass index was 22.58 ± 3 kg/m2. Chest inspiratory mechanics also showed a low positive correlation with posterior muscle mobility (r = 0.381; p = 0.038). There was no significant change in PAT. Within the framework of the myofascial theory, stretching exercises that can contribute positively to the musculoskeletal and respiratory system structures of healthcare professionals can be recommended and encouraged to healthcare professionals.
