This opinion is increasingly supported by evidence from retrospective analysis of trauma centre admissions for equestrian related incidents (ERI’s), albeit from relatively low numbers. The most common approach to reducing severity of ERI’s has focussed on encouraging the wearing of riding helmets and to a lesser extent, air-jackets and or body-protectors. Horse riders in the UK were surveyed to ascertain their experience of falls while riding in the preceding 12 months. A total of 3,757 responses were received with a subset of 1,977 complete surveys analysed. The majority of respondents were female (97%, n = 1,914). Falling off once in the last 12 months was most common (53.4%; n = 1,055); 24.2% (n = 478) had fallen off twice, 11.4% (n = 225) three times and 6.5% (n = 129) more than 5 times. Respondents were asked to specify the activity they were undertaking when their last fall occurred; hacking/trail riding (25.9%; n = 513), schooling on the flat (25.8%; n = 511) and showjumping schooling (19.4%; n = 384) were the three most common activities where falls took place. Horses changing direction rapidly (40.9%; n = 808) or rearing/bucking (23.8%; n = 470) were the most common reasons for rider falls, with most (73%; n = 1,443) riders falling off the side of the horse. Riders were most likely to injure their back (51%; n = 1,008), shoulders (39%; n = 771) or pelvis (37%; n = 731) when they fell off, but most injuries were self-rated as minor. Severe injuries as a result of a fall were more common when the riders’ head, back, shoulder or ankle was injured. A variety of factors appear to be involved in rider falls from horses, and many of these may be modifiable and hence preventable.","PeriodicalId":505672,"journal":{"name":"Comparative Exercise Physiology","volume":"4 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141344817","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}

Hence the judokas are susceptible to injuries. Specific training and physical conditioning help the judoka perform efficiently with minimal risk of injuries. The judo9+ injury prevention protocol consisting of sport-specific exercises focuses on minimising lower limb risk factors. The objective of the study was to investigate the effects of judo 9+ injury prevention protocol on strength, balance, and anaerobic fitness in elite judokas. A sample of 20 (male and female elite judokas) aged between 20-40 years, were recruited in the study based on selection criteria. After demographic and baseline evaluation, the judo9+ injury prevention protocol was administered to each participant for four weeks (2 sessions/week). Balance (SEBT), lower limb strength (VJHT), and anaerobic fitness (SJFT) scores were administered before the training began and after the completion of the training. Pre-post-training changes were compared using, using the paired t-test. All the outcome measures, SEBT, VJHT and SJFT demonstrated statistical significant changes () following four weeks of judo9+ injury prevention training. Larger effect sizes of 0.94 and 1.42 with >90% power were reported in VJHT and SJFT, respectively. There is sufficient evidence from this study to confirm that judo9+ injury prevention training significantly improves lower limb strength and anaerobic fitness among elite judokas following four weeks of judo9+ injury prevention training. However, balance improvement might require longer duration.","PeriodicalId":505672,"journal":{"name":"Comparative Exercise Physiology","volume":"23 35","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141379298","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}

A systematic search adhering to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines and randomised controlled trial (RCT) studies that met the inclusion criteria was conducted in the databases of Google Scholar, PubMed (MEDLINE), Scopus, Embase, and Web of Science from January 1, 2020, to March 18, 2024. One hundred and thirty-nine articles were retrieved, of which 13 randomised controlled trial studies met the inclusion criteria. The findings of these studies showed that performing various exercises, including water sports, resistance, aerobics, Tai Chi, Qigong, and Baduanjin exercises across varying intensities from low to high, can improve the quality of sleep of elderly women.

Despite the existence of vast literature, there is lack of comparison of low versus submaximal versus maximal intensity required for preconditioning. The aim of the study was to compare the muscle damage and RBE at various intensities of eccentric exercise in active young men. Thirty-six healthy, physically active men were recruited and randomly assigned to three different groups low-high (L-H, n = 12), submaximal-high (M-H, n = 12) and maximal-high (H-H, n = 12). All participants performed 2 exercise bouts separated by 14 days. L-H, M-H and H-H groups performed low (10% of 1RM), moderate (50% of 1RM) and high (90% of 1RM) intensity eccentric exercise for knee extensors, respectively, in the 1st bout followed by high (100% of 1RM) intensity in the second bout. Muscle soreness (SOR), thigh circumference (CIR), maximal voluntary isometric contraction (MVIC), range of motion (ROM) and blood lactate (Bl Lac) were measured before, immediately, at 24 h, at 48 h and at 72 h after exercise. A significant effect of time appeared for MVIC (), CIR (), ROM () and Bl Lac (). The bout × time interaction, as well as bout × time × group interaction was also found significant indicating changes in muscle strength and ROM. Circumference changed significantly with a significant bout × group interaction effect . SOR () was significant between the bouts. Therefore, exhibiting attenuation of muscle damage markers after the second bout. Findings of the present study showed that muscle damage was evident at all three intensities.

Detrended fluctuation analysis (DFA) is a heart rate variability variable proposed as a non-invasive tool for exercise intensity monitoring and with a potential association with exercise intensity thresholds and fatigue. The objectives of this study were to (1) describe the first component of DFA (DFA-α1) during standardised field incremental exercise tests in sport horses in active Eventing competition and in sport horses ridden without the goal of participating in competitions, and (2) to determine if DFA-α1 is associated with blood lactate concentration. Null hypotheses of the study were that (1) DFA-α1 is not correlated with blood lactate concentration measurements and (2) the correlation between DFA-α1 and blood lactate concentration is not stronger than the one between blood lactate concentration and heart rate or blood lactate concentration and speed. An in vivo observational study was performed analysing exercising electrocardiograms obtained in 59 standardised exercise tests in the field. DFA-α1 was significantly and moderately correlated with blood lactate concentration (, ). A strong correlation was observed between blood lactate concentration and speed (, ), as well as between blood lactate concentration and heart rate (, ). DFA-α1 correlation with blood lactate concentration was moderate but weaker than the correlation of blood lactate concentration and heart rate or blood lactate concentration and speed. DFA-α1 was not a useful surrogate of blood lactate concentration in field incremental standardised tests used for sport horses in this setting.","PeriodicalId":505672,"journal":{"name":"Comparative Exercise Physiology","volume":"43 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139797256","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}
