Velodrome cycling is a sport that requires cycling on an inclined surface, and this may increase chances of injury in players. The purpose of this study was to find out the injury pattern in form of injured part, injury time, severity, type and relation with gender, level of participation and training characteristics among velodrome cycling players. Injury pattern from the last 2 years was studied in 85 velodrome cycling players aging between 15-25 years from Punjab using a scheduled interview method. The study included players who were practicing cycling at least 3 times per week for more than 2 years. The mean age of the study participants was 19.39 years (range 15-25). According to the results of this study, 48 out of 85 cyclists had sustained 75 injuries in the last 2 years, in which 52% (39) injuries were due to fall, 66.67% were traumatic injuries and 84% occurred during training time. The most commonly injured parts were shoulder and knee. For the shoulder, the clavicle was the most frequently fractured bone (11 cases) among the 85 cyclists. The severity of injuries calculated according to Ekstrand’s 3-point scale based on absence from the sports activity depicted most injuries as severe (39.58%) followed by mild (33.33%) and moderate (27.08%). It can be concluded that females were injured more as compared to male velodrome cyclists. The most common injured parts were shoulder in upper limb and knee in lower limb.

Delayed onset muscle soreness (DOMS) is a condition that happens following eccentric or intensive exercises. Whole-body vibration (WBV) is a potential treatment for DOMS; however, there is a lack of studies assessing its effectiveness in the untrained population. Our study objective was to test the efficacy of WBV compared with no treatment on pain and knee strength in healthy adults with DOMS. We randomly allocated 52 participants, 12 men and 40 women, aged 18 to 28 years, into WBV (n=26) and control (n=26) groups. The eligibility criteria included no history of injury, strengthening or aerobic exercises within the past six months. The participants walked on a treadmill to introduce DOMS. 24 h later, the WBV group received one session of WBV treatment, with their knees bent to 60° for 1 min (frequency, 30 Hz; amplitude 2-5 mm). We assessed pressure pain threshold (PPT), visual analogue scale (VAS), and knee maximum isometric force (MIF) at four time points. We did a one-way repeated measures ANOVA of each outcome measure, followed by a t-test and Bonferroni post-hoc test. The between-group differences were not significant at the baseline and 24 h post-DOMS (P>0.05). Statistical analyses revealed significant differences between the two groups for all variables at 96 h post-DOMS inducement (P<0.05), with mean differences for PPT, MIF and VAS being 1.19 kilo Pascals (95%CI = 0.78-1.32), 42.87 Newtons (95%CI = 28.53-56.98), and -2.39 (95%CI = -3.13- -1.98), respectively. Moreover, differences between the two groups were statistically significant for MIF 168 h post-DOMS (P<0.05). WBV can effectively improve pain and muscle strength; therefore, beneficial treatment for recovery of DOMS symptoms. However, determining the exact dose, frequency, and best time of application is pending future research. Iranian Registry of Clinical Trials registration number: IRCT2016092429958N1

Evidence propose that dietary intake affects physical performance and body composition. The present study aimed to determine the relationship between dietary inflammatory index (DII) with physical function and anthropometric indices in the marine. This cross-sectional study was performed on 300 males aged 18 to 45 years serving in the Navy. A general questionnaire was used to collect demographic data of participants. Also, the anthropometric indices (height, weight, waist circumference, and hip circumference) were measured to calculate a body shape index (ABSI), abdominal volume index (AVI), body adiposity index (BAI), and conicity as new anthropometric indices. Moreover, the 12-min Cooper, sit up, pull up, and push up were used to assess physical performance. Food intake over the past year was assessed using a 147-item food frequency questionnaire, and then the DII score was calculated for each subject. Aerobic performance was assessed using the Cooper test. Also, the repetitions of sit up, pull up and push up in 1 minute were recorded to assess muscular endurance. The present study showed that the increase in DII is directly related to body mass index (BMI) (P=0.04), body fat percentage (P=0.03), and BAI (P=0.010) and inversely related to VO2max (P=0.001). However, after adjusting for the effect of energy intake in regression model, only the association between DII and VO2max was statistically significant (β=-1.69, standard error=0.67, P=0.01). The increase in the dietary inflammatory potential is associated to a higher BMI and body adiposity and a lower aerobic capacity in military personnel. However, the observed relationship between DII and anthropometric indices seems to be influenced by the energy intake. Further well-designed studies with a prospective method are warranted.

Back pain is a common clinical condition that leads to poor performance in racehorses. Therefore, horse owners would benefit from a suitable and effective treatment that results in the early recovery of their horses. Dermal suctioning significantly improves chronic lower back pain in humans. Thus, if a similar effect were to be found in racehorses, it could become a new treatment for back pain in horses. In this study, we examined the acute effects of dermal suctioning on back pain in racehorses. Twelve Thoroughbred racehorses with back pain underwent 10 min of dermal suctioning in the thoracolumbar region. The pain score, mechanical nociceptive threshold (MNT), heart rate variability (HRV), and plasma cortisol concentrations were measured. Results showed that pain scores were significantly improved immediately after dermal suctioning (P=0.028), while MNT, HRV, and plasma cortisol concentrations did not show significant changes (P>0.05). These results indicate that dermal suctioning immediately relieves pain but has a limited effect on the other three parameters.

Type 2 diabetes mellitus (T2DM) is characterised by the chronic hyperglycaemia which leads to various micro and macrovascular complications. The aim of present study was to evaluate the impact of talk test based aerobic exercise on glycaemic control and anthropometric measures among adults with (T2DM). In this double blind randomised controlled trial (RCT), aerobic exercises/walking was used as intervention. The patients were divided into three groups based on the tool of exercise intensity prescription: a talk test-based group (TTG, n=30), a rating of perceived exertion-based group (RPEG, n=30), and a control group (CG, n=30). Glycated haemoglobin (HbA1c) was evaluated at baseline and after 8 weeks. Anthropometric measures, i.e. body mass index (BMI), and waist circumference (WC) were evaluated at baseline, 4 weeks, and 8 weeks. Wilcoxon rank-sum/repeated measure of ANOVA and Kruskal-Wallis test/ANOVA were used for within and between group comparison, respectively, on the basis of normality of the data. The mean HbA1c change in TTG, RPEG, and CG was -0.29, -0.28, and -0.04, respectively, and it was significantly greater in TTG and RPEG as compared to CG. The reduction of HbA1c, BMI, and WC was reported in each group. However, the reduction in the experimental groups, i.e. TTG and RPEG was significantly greater than in the control group (P≤0.01). However, there was no significant difference found between the experimental groups (P>0.05). TT based aerobic exercise is effective in improving glycaemic control and anthropometric measures. Therefore, TT can be used for the exercise prescription of these patients. The study is registered at the Clinical Trial Registry-India under no. CTRI/2019/02/017531.

This study aimed to investigate the short and long-term effects of concurrent exercise training on anthropometric variables, HDCA2 activity and cortisol levels of individuals with schizophrenia (SZ). Therefore, 10 patients were submitted to the program (endurance and strength exercises in the same session, 60 min of duration, three times a week) and blood samples were collected before, 30 days and 180 days after the intervention started. Exercise training reduced the body mass index and body mass after 180 days of the intervention. A significant decrease on HDAC2 activity was found 180 days after intervention compared to before the intervention. The cortisol levels remained unchanged in any evaluated time-points. The concurrent exercise training was able to modulate HDAC2 activity in mononuclear cells and improve anthropometric variables in a time-dependent manner in patients with SZ.

A wide range of cognitive disorders, long-term potentiation (LTP) disorders, and biochemical changes have been reported in labyrinthectomy situations in the hippocampus of rodents. In order to investigate whether exercise and/or curcumin induce LTP and increase neurons in the hippocampus of unilateral labyrinthectomy male rats, after undergoing labyrinthectomy, animals were subjected to treadmill exercises after the intraperitoneal injection of curcumin five days per week, for 30 days. An increase of LTP and neuron count of the hippocampus was observed in unilateral labyrinthectomy rats. Interestingly the combination of exercise and curcumin did not enhance LTP in unilateral labyrinthectomy rats. These findings demonstrated that treadmill exercise and curcumin individually, significantly affect reinforcement of many of the pathological processes playing a role in increasing memory in unilateral labyrinthectomy situations.

Menopause is characterised by several hormonal changes through which women undergo aging. These changes lead to psychological, somatic, urogenital and vasomotor symptoms that influence the quality of life of women. Studies have shown that physical exercise can benefit women in the pre- and postmenopausal stages. However, the physiological benefits of exercise during the menopausal period have been less explored, as well as which type of exercise is most recommended at this stage of life. Therefore, the present review aimed to investigate the physiological changes promoted by the practice of physical exercise during the menopause period. A search for scientific articles was performed in the PubMed database using the descriptors ‘menopause’ and ‘exercise’ and the ‘AND’ connector. The period selected for this study was from 2014 to 2018. After applying the inclusion and exclusion criteria, five articles were selected. As a result, studies suggest that physical exercise promotes hormones, body composition and positive cardiovascular changes, decreases menopausal symptoms and improves psychosocial health. In addition, it is associated with an improvement in the quality of life.

This study investigated whether the modifications made to Grand National (GN) fences at Aintree, Liverpool, UK in 2012 following the Review of Safety and Welfare commissioned by the British Horseracing Authority (BHA), reduced the number and severity of ridden horse falls. The study also investigated whether the number of fences in a race and the total starters were positively linked to falls, and whether horse and jockey experience had any bearing. Videos of 36 races run between 2008 and 2016 recording all horse falls were retrospectively reviewed. Eighteen of the races were run prior to the 2012 changes made to the fences and 18 after the modifications. Falls were graded using a pre-determined severity scale, and previous experience of jumping GN fences. The severity scale was developed by the authors based on the literature and their perception of the degree of injury caused to the rider. The number of falls pre- and post-GN fence modification were adjusted to generalised linear models using the number of falls and severity of falls as dependent variables. A significant decrease in fallers was seen (P<0.001) after changes were made to the GN fences, together with a reduction in the probability of all levels of severity of fall. The severity scores decreased with increasing number of fences (P<0.001). When there were more starters in a race, a greater probability of horse falls was observed (P<0.001). No positive association between horse’s experience of jumping GN fences and horse falls, or jockey licence and horse falls was found (P>0.05). This study revealed that by implementing the changes recommended by the BHA, which included modifying the GN fences, the number and severity of ridden horse falls decreased. Horse and rider welfare was improved, contributing positively to the debate and public perception of the horseracing industry.

Eighteen of the races were run prior to the 2012 changes made to the fences and 18 after the modifications. Falls were graded using a pre-determined severity scale, and previous experience of jumping GN fences. The severity scale was developed by the authors based on the literature and their perception of the degree of injury caused to the rider. The number of falls pre- and post-GN fence modification were adjusted to generalised linear models using the number of falls and severity of falls as dependent variables. A significant decrease in fallers was seen (P<0.001) after changes were made to the GN fences, together with a reduction in the probability of all levels of severity of fall. The severity scores decreased with increasing number of fences (P<0.001). When there were more starters in a race, a greater probability of horse falls was observed (P<0.001). No positive association between horse’s experience of jumping GN fences and horse falls, or jockey licence and horse falls was found (P>0.05). This study revealed that by implementing the changes recommended by the BHA, which included modifying the GN fences, the number and severity of ridden horse falls decreased. Horse and rider welfare was improved, contributing positively to the debate and public perception of the horseracing industry.","PeriodicalId":10709,"journal":{"name":"Comparative Exercise Physiology","volume":"37 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82186806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two-dimensional (2D) fluoroscopy has been used in shoulder pathologies to estimate the humeral head position (HHP) in the true anteroposterior (AP) view. However, there is a lack of evidence regarding the reliability estimating it in the axillary view and in measuring the shoulder joint space width (JSW). True AP view images (n=36) of subjects with adhesive capsulitis were taken in supine in multiple arm abduction positions. The axillary view images (n=48) were taken in supine and prone in 75° of abduction. The HHP was assessed in the glenoid reference frame. The position and radius of the humeral head along with the superior, inferior, anterior, posterior, and middle JSWs were measured in each image. All the images were coded and randomly presented twice to a physiotherapist at a gap of 48-72 h for intra-rater reliability and to 2 therapists and an orthopaedic surgeon for inter-rater reliability. Reliability was expressed using intraclass correlation coefficients (ICC) and standard error of measurement (SEM). In both the views, inter-rater, and intra-rater reliability was excellent for the radius of the humeral head (inter-rater – 0.95-0.97 and intra-rater -0.98)], moderate (ICC: 0.70 and 0.76), and excellent (ICC: 0.89 and 0.93) for HHP. The reliability for JSWs was moderate to good (ICC: 0.66-0.82) for inter-rater and good to excellent (ICC: 0.75-0.95) for intra-rater analysis. The SEM for HHP and JSWs were <0.4 mm for intra-rater analysis, and <0.7 mm for inter-rater reliability in both views. The study demonstrated that the glenohumeral arthrokinematic parameters can be measured with good to excellent levels of reliability when using 2 D fluoroscopy. The study is part of a clinical trial (Clinical Trial Registry India: CTRI/2018/12/016657).
