As a result of COVID-19 illness epidemic, a worldwide health emergency has been proclaimed. The educational sector, whose old systems have been replaced by online educational systems, was particularly impacted by the state of lockdown. Prolonged and frequent sitting in front of monitors, which, by maintaining the same posture for an extended period of time, causes cumulative trauma disorder. The purpose was to evaluate effect of four-week scapular strengthening exercises on neck disability and scapular position in subjects with rounded shoulders. In this experimental study, 30 college students between ages of 18 and 22 were enrolled. They were randomly divided into two groups, the Experimental group and the Control group, each having 15 participants. The experimental group received scapular strengthening exercises along with conventional treatment whereas the control group received conventional treatment only. Over the course of four weeks, both groups received training sessions three times a week. The neck impairment and scapular position were assessed before and after intervention. Both groups had made considerable improvements, although the experimental group experienced less pain and had a better scapular posture than the control group. Results demonstrated that the experimental group outperformed the control group statistically in terms of improvement in neck disability and rounded shoulder posture.

Adhesive capsulitis causes adaptive shortening of the non-contractile structures around the shoulder joint which may affect the distraction distance or joint space width (JSW) between the glenoid and humeral head. Joint traction is a commonly used manual therapy technique to reduce pain and gain range of motion in patients with adhesive capsulitis. However, changes in JSW with manual traction are not objectively assessed. This study aimed to find differences in shoulder JSW with different grades of traction and made comparisons between the affected and the unaffected side using 2D fluoroscopy. Forty-one subjects (24 males, 17 females; age 53.9±7.9 years) diagnosed with adhesive capsulitis with low to moderate joint irritability were included. Their mean duration of symptoms was 5.25±1.7 months. True anteroposterior view images of the shoulder were taken with the patient in a supine position with their arms held at 75° of abduction. Images of the affected and unaffected side were taken while no traction, grade 2 and grade 3 manual traction were applied. The JSW was determined as the linear distance between the articular surfaces. Repeated measures ANOVA with post hoc testing was used for analysing differences across the sides (affected and unaffected side) and conditions (No, grade 2 and grade 3 traction). There was no significant interaction between conditions and sides (P=0.99). Averaged across sides, the JSW with grade 2 or 3 traction was 0.18 and 0.23 mm more than the no traction condition (P=0.013 and P=0.001, respectively). There were no differences in the JSW with grade 2 or 3 traction. Averaged across the conditions, the JSW on the unaffected side was 0.21 mm more than the affected side (P=0.03). The study demonstrates that adhesive capsulitis causes a reduction in JSW at 75° abducted position and grade 2 or 3 manual traction can significantly increase this JSW.

粘连性囊炎导致肩关节周围非收缩性结构的适应性缩短，这可能影响肩关节和肱骨头之间的牵张距离或关节间隙宽度(JSW)。关节牵引是一种常用的手工治疗技术，用于减轻粘连性囊炎患者的疼痛和增加活动范围。然而，人工牵引下JSW的变化并没有得到客观的评估。本研究旨在发现不同牵引程度下肩关节关节痛的差异，并利用二维透视对受影响侧和未受影响侧进行比较。41例受试者(男性24例，女性17例;年龄53.9±7.9岁，诊断为粘连性囊炎，伴低至中度关节过敏性。平均症状持续时间为5.25±1.7个月。在患者仰卧位，手臂外展75°时拍摄肩部的真实正位图像。在不牵引，2级和3级手动牵引的情况下，拍摄患侧和未受影响侧的图像。JSW确定为关节面之间的线性距离。采用事后检验的重复测量方差分析来分析两侧(受影响和未受影响的一侧)和情况(2级和3级牵引)的差异。条件与侧面间无显著交互作用(P=0.99)。2级和3级牵引的JSW比无牵引的JSW平均侧长0.18 mm和0.23 mm (P=0.013和P=0.001)。2级或3级牵引的JSW无差异。在所有条件下平均，未受影响侧的JSW比受影响侧多0.21 mm (P=0.03)。研究表明，粘连性囊炎导致75°外展位置的JSW减少，2级或3级手动牵引可显著增加JSW。印度临床试验注册中心:CTRI/2018/12/016657。

Forward head posture is a common abnormal posture characterised by weakness of muscle around neck and shoulder. Persistent forward head posture can impair respiratory functions and cervical proprioception. The aim of this systematic review and meta-analysis is to determine the effectiveness of exercises to improve the forward head posture. The online literature search performed on various databases, i.e. PubMed, Cochrane, PEDro, Science Direct and Scopus databases resulted in 601 articles, but only 11 articles were found relevant to perform meta-analysis. The primary outcome measure was craniovertebral angle and other outcome measures were neck pain, cranial angle, cranial rotation angle and Neck Disability Index (NDI). Methodological quality of studies was assessed by PEDro scoring and risk of bias assessment was performed using Cochrane collaboration tool of risk of bias. Results of meta-analysis revealed that craniovertebral angle (CVA), cranial rotation angle (CRA), visual analogue scale and NDI improved significantly (P<0.00001) in forward head posture participants who followed any type of exercise regime compared to the participants who did not follow any exercise program. However, cranial angle was not found significantly (P=0.73) improved in exercise groups. Exercises are effective in improving postural parameters, such as CVA, CRA and pain and neck disability in subjects with forward head posture. Systematic analysis registry at PROSPERO: CRD42020175372

Upper crossed syndrome (UCS) is characterised by distortion or imbalances of various muscles that put tension on the nearby tendons, bones, and joints leads to muscle weakness, tiredness, sore shoulder blades, headache and limitation of movements. The rationale of the present study was to evaluate the efficacy of various exercises (McKenzie and TheraBand exercises) on posture, pain and strength in patients suffering with upper crossed syndrome. The participants were randomly allocated into two groups: Group 1 (McKenzie group, n=15) and Group 2 (exercise group, n=15). Outcome measures were pain and disability using SPADI questionnaire and muscle strength using manual muscle testing. Group I received McKenzie exercises for 3 weeks, 5 sessions per week, whereas Group II received TheraBand exercises for 3 weeks, 5 sessions per week. Data analysis was done by using paired t-test for within group comparison and unrelated t-test to evaluate the between group differences in each outcome variable. The results indicated a statistically significant improvement in pre-/post values of pain & disability in the McKenzie group (t=7.60 and P=0.0001), and in the exercise group (t=8.25 and P=0.0001). Results also suggested a statistically significant improvement in the strength of serratus anterior (t=4.52 and P=0.0001), cervical flexors (t=4.12 and P=0.001), and rhomboids (t=4.14 and P=0.001) in the McKenzie group and strength of serratus anterior (t=5.17 and P=0.0001), cervical flexors (t=4.18 and P=0.001), rhomboids (t=4.18 and P=0.001) in the exercise group. Results indicated that the exercise group showed better improvement as compared to McKenzie group in terms of pain and disability. Results also stated that both groups were equally effective in improving muscle strength.

Several reports have suggested that the risk of exertional heat illness (EHI) in Thoroughbred racehorses increases in high ambient temperatures. Heat dissipation in horses during exercise becomes less efficient when the body temperature and ambient temperature are close. Therefore, we hypothesised that exercise at 40 °C may increase body temperature, oxygen consumption, and cardiac output during incremental exercise tests compared to 20 and 30 °C. Six trained Thoroughbred horses were studied in a randomised, crossover design at three ambient temperatures with a 6-day washout period. Using a 3% inclined treadmill, horses performed incremental exercise tests at 1.7, 3.5, 6, 8, and 10 m/s for 90 s at ambient temperatures of 20, 30, and 40 °C. The effects of ambient temperature at 10 m/s on physiological variables were analysed using mixed models (P<0.05). Pulmonary arterial temperature and rectal temperature at 40 °C were higher than those at 20 °C (P<0.001) and 30 °C (P<0.001). Similarly, oxygen consumption (vs 20 °C, P=0.009; vs 30 °C, P=0.006) and cardiac output (vs 20 °C, P=0.001; vs 30 °C, P=0.001) at 40 °C were higher than those at 20 and 30 °C. Arterial O2 partial pressure, O2 saturation, and pH at 40 °C were lower than those at 20 and 30 °C. Arterial CO2 partial pressure at 40 °C was higher than that at 20 and 30 °C. No differences were observed in arterial-mixed venous O2 concentration difference (P=0.391) and plasma lactate concentration (P=0.134) at different ambient temperatures. These results indicate that exercise at 40 °C causes excessive high body temperature, decreased running economy, and increased cardiac output compared to exercise at 20 and 30 °C. We strongly suggest that trainers and veterinarians should anticipate the occurrence of increased thermal stresses when ambient temperature is extremely high even in dry conditions and prepare to mitigate the risk of EHI from the perspective of equine welfare.

In this study, the cytokine response (interleukin-6; IL-6), free oxygen radicals which are claimed to be responsible for the damage in the kidney tissue of exercise-trained rats and untrained-rats, and antioxidant levels were investigated after being forced to an exhausting run. Forty male Wistar albino rats were assigned to the following groups: sedentary controls (C); untrained animals that acutely completed the exhaustive exercise and were sacrificed immediately after exhaustion (UT-i) or 1 day after exhaustion (UT-1); and long-term trained animals that completed the exhaustive exercise and were sacrificed immediately after exhaustion (T-i) or 1 day after exhaustion (T-1). In UT-i and 1 day after exhaustion (T-1) groups, total oxidant status levels were increased compared to controls (P<0.05). IL-6, which is reported to have an anti-inflammatory effect in exercise, did not increase in untrained group immediately, but started to increase 1 day after exhaustion compared to controls. IL-6 levels were significantly increased in the T-i and T-1 groups compared to the control and UT-i groups (P<0.05). The level of total antioxidant status did not show a significant increase in the UT-i group but started to rise after exhaustion the T-1 group. IL-6 levels were significantly increased in the T-i and T-1 groups compared to the control, UT-i, and UT-1 groups (P<0.05). As a result, while oxidant stress and antioxidant mechanism increased immediately in the trained group, IL-6 increased significantly immediately and 1 day later. In the untrained group, however, an increase was observed in oxidant stress, antioxidant mechanism, and IL-6 levels after 1 day.

Here, we aimed to explore the therapeutic effect of voluntary wheel running (VWR) in high-fat diet-fed rats on pulmonary tissue injury via the modulation of autophagic response. Thirty-two rats were allocated into four groups; normal diet (Control); VWR; high-fat-diet (HFD), and HFD + VWR. After three months, pathological effect of HFD on pulmonary tissue was investigated. The levels of tumour necrosis factor (TNF)-α were detected in the bronchoalveolar lavage fluid (BALF). We monitored the expression of interleukin (IL)-6 and autophagy-related genes in lung tissues. H&E staining showed pathological changes in HFD group coincided with the increase of TNF-α levels in the bronchoalveolar fluid compared to the normal rats. Our results showed the up-regulation of IL-6, becline-1, LC3 and P62 in the HFD group compared to the Control group. VWR inhibited HFD-induced changes and could decrease HFD-induced changes via the regulation of autophagy status.

With this study is intended to analyse, compare and evaluate the predictive factor of leg power on shooting speed and fatigue levels in young futsal athletes in order to establish effort patterns in these ages, to prescribe training sessions adequately in terms of external/internal load. The study had 32 participants, male, aged between 12 and 17 years (Mean = 14.56}1.66). Participants were evaluated in relation to their lower limb power through the Chronojump system, the speed was measured through a radar placed on the goal line, and in relation to their fatigue levels through the Running Anaerobic Sprint Test (RAST). To identify the differences between groups, the tests of Kruskal Wallis and Mann Whitney were used, and also a simple linear regression tests for predictive values between variables. In relation to the shots speed, higher values were found in the older groups (P≤0.001), which is directly and significantly related to the higher values of lower limb power, also verified in the older athletes (P≤0.001). In relation to the fatigue levels, it increases as the age of the athletes is higher, verifying that the power of the lower limbs is a predictor variable of the fatigue index (P≤0.001). The analysis conducted indicate that there are significant differences in the association between shooting speed, lower limb power and fatigue indices according to the players levels studied.

Functional scoliosis is defined as the reversible and temporary lateral spinal curvature that mainly occurs due to abnormal postural habits that leads to non-structural and compensatory changes in spine. Functional scoliosis can lead to the development of mental health issues, such as stress, anxiety and depression. The purpose of the present study was to evaluate the effects of spinal manipulation techniques and Schroth exercises on psychological parameters in patients with functional scoliosis. The subjects were randomly allocated into experimental (n=31) and control group (n=31). Spinal manipulation techniques and Schroth exercises were given to the patients of experimental group, while only Schroth exercises were given to the patients of control group. Outcome measures were Depression, Anxiety & Stress Score that was examined by using ‘DASS-21 questionnaire’. Treatment was given for four weeks, thrice weekly. After the completion of four weeks, DASS scores were obtained from the participants. Patients were followed up after 2 months and data was collected again. Repeated measures ANOVA were used to compare the mean changes within-group. Independent t-test was used to analyse the mean improvement between-group. Results suggested that there was a statistically significant difference between pre-/post and pre-/follow-up scores of the DASS, but there was statistical non-significant difference between post-/follow-up scores of the DASS. Results also suggested that experimental group showed better improvement compared to the control group. This study concluded that the combine use of spinal manipulation techniques and Schroth exercise protocol can significantly reduce the psychosomatic symptoms in functional scoliosis.
