The aim of the study was to establish whether RAE is evident in equestrian sport and to identify whether rider sex has an effect on ranking. Data were collected from FEI results pages for Endurance, Dressage, Eventing and Showjumping. Birth date and quartile was compared at U18, U21, U25 and Senior in each sport. Chi-squared and Kruskal-Wallis were used to identify any RAE and whether there was a ranking difference between quartiles. A Mann-Whitney U test identified any ranking difference between sexes. No RAE was found in any sport or age category, however there were differences identified in sex for both ranking and participation. Males were shown to rank higher in jumping sports (senior) whereas females were ranked higher in Dressage and Endurance (all age categories). Further studies are required to evaluate the psychosocial factors and development structures in equestrian sport development can affect success. Results question whether a sex difference exists that requires further research into the sex-integration of all equestrian sport.","PeriodicalId":10709,"journal":{"name":"Comparative Exercise Physiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140734549","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}

Group A received hip abductor strengthening along with quadriceps strengthening exercises, Group B received iliotibial band stretching along with quadriceps strengthening exercises and Group C received conventional knee exercises. The treatment duration was three sessions per week in alternate days for 3 weeks. The outcome measures were pain, physical performance and quality of life, which were evaluated at the baseline and after 3 week of intervention with the visual analogue scale, chair sit to stand test and knee injuries and osteoarthritis outcome score questionnaire. All the three groups showed statistically significant improvement in pain, physical performance and quality of life in patients with knee OA. Hip abductor strengthening exercises group showed more significant improvement in pain, physical performance and quality of life than the Iliotibial band stretching exercises group.

The present study aimed to investigate the effect of combined training (resistance endurance) and omega-3 supplementation on the levels of inflammatory and anti-inflammatory cytokines in older women. The 40 participating older adults, with an average age of 66.7 ± 4.13 years, were randomly assigned to four groups: placebo, omega-3, training and training + omega-3. Combined exercise training (consisted of 30 mins running with 40-70% of reserve heart rate and resistance training included ten exercises, two sets, and each set consisted of 18-20 repetitions) performed for eight weeks and three sessions per week. Omega-3 supplementation was 2,000 mg daily (two 1000 mg capsules, one in the morning and one at night). Blood sampling was performed in pre and post-test (48 h after the last training session and omega-3 supplementation) stages, and interleukin (IL)-6, tumour necrosis factor (TNF)-α, and IL-10 levels were measured by ELISA. The dependent t-test results (pre- and post-test) indicated that there was a statistically significant difference (decrease) in HOMA-IR index, body fat percentage, body mass index, IL-6, and TNF-α in training and training + omega-3 groups, post-exercise (). TNF-α was lower in the omega-3 () training () and training + omega-3 () groups compared to the placebo group, post exercise. Moreover, IL-6 levels in the training () group were lower than in the placebo group, post exercise. Combined training may reduce both TNF-α and IL-6 compared to placebo. In contrast, omega-3 alone or combined with combined training may only reduce TNF-α but not IL-6 concentrations compared to placebo.","PeriodicalId":10709,"journal":{"name":"Comparative Exercise Physiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140086580","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}

Dressage, Eventing, and Jumping horses (n = 248) arrived at 05:00-06:30 h on six European and two Australian overnight chartered flights 8-to-10 days prior to beginning competition. All horses were housed at Japan Racing Association Equestrian Park in Bagi Koen. Eventing Cross Country was held an hour’s drive away at Sea Forest. All stables and conveyances were air-conditioned. Cooling stations were available at both venues and consisted of tall arched tents with large containers of water chilled to ≤15 °C, cooling/misting fans, and rubberised flooring for traction safety. Training hours began at 06:00 h daily with a mandatory mid-day break between 11:00 and 15:00-16:00 h when arenas were re-opened until 22:00. Daytime temperatures ranged 28.8-36.8 °C and peak humidity remained high throughout the Games (58-97%). There were no heat-related illnesses in horses observed by clinic veterinarians who were present at all training and competition rings whenever horses were exercising. Individual horses received elective intravenous fluids (10 litre minimum) on arrival in Japan, after cross country, and/or before departure. Reported ailments included post-transport pneumonia, exercise-induced pulmonary haemorrhage, orthopaedic injury, laceration, impaction colic, acute piroplasmosis, and laminitis.

Prolonged FHP eventually leads to muscle imbalance, postural instability, and can advance the progression of cervical disorders. Early intervention through screening may help to prevent this posture from being symptomatic. Therefore, correction of FHP through exercise regimen is necessary. Callisthenic exercises (CE) and motor control exercises (MCE) are known to improve muscle imbalance. Hence, it was hypothesised that CE and MCE would have positive effects on craniovertebral angle (CVA) and postural stability in asymptomatic FHP. This randomised clinical trial recruited 30 individuals aged between 18 and 40 years with asymptomatic FHP. The CE group received callisthenic exercises whereas MCE group received motor control exercises, thrice weekly for 4 weeks. The outcome measures were CVA, postural stability [risk of fall (ROF), stability index (SI), and anterio-posterior sway (AP sway)] and craniocervical flexion endurance (CCFE), which were assessed using photographic method, TETRAX, and pressure biofeedback unit (PBU), respectively. Paired t-test for within group analysis showed statistically significant improvement in all the outcomes for both the groups (). Between group analysis by independent t-test revealed that both groups had similar improvement in CVA () and CCFE () but CE showed better improvement for postural stability () than MCE. CE and MCE are effective in improving CVA, postural stability, and CCFE in individuals with asymptomatic FHP.

The immune system functions to distinguish between ‘self’ and ‘non-self’ and is composed of innate and adaptive immune cells. Exercise, especially regular moderate-intensity exercise, has positive effects on the immune system, including enhanced vaccination responses, reduced inflammation, improved neutrophil activity, and longer leukocyte telomeres. Sedentary lifestyles contribute to an increased risk of diseases, while regular exercise is beneficial for immune function and overall health. The effects of exercise on the immune system depend on factors such as exercise intensity, duration, and type. Exercise-induced immune responses vary in different populations, including young and elderly individuals, with variations in the magnitude and extent of the effects. Exercise has been associated with reduced immunosenescence and improved vaccine-induced immunity. Factors such as age, sex, genetics, microbial diversity, and environmental influences also impact immune function. Understanding the complex relationship between exercise, external factors, and immune responses is important for developing tailored interventions and improving health outcomes. More research is needed to fully understand the mechanisms and implications of exercise on the immune system. The objective of the study was to assess the impact of exercise on variations of the immune system caused by various factors, providing further insights into the complex relationship between exercise and immunity.","PeriodicalId":10709,"journal":{"name":"Comparative Exercise Physiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440042","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}
