Animals were randomized distributed to a control group (CG, n=5) or to an exercised training group (EE, n=10), which performed a treadmill running training (-20º; from 25m/min, progressive increase of 1.25m/min per day; 60min) for 6 times/week being sacrificed 1 (EE1, n=5) and 3 weeks (EE3, n=5) after the beginning of the training program. Body weight, food intake, hair appearance, ability to perform work, and animals’ behavior were measured during the protocol. After sacrifice, SOL and TA muscles were collected for histological analysis. Both showed muscle damage signs in EE1 and EE3 through the increase of cell degeneration, tissue necrosis, and inflammatory activity. However, no OTS signs were observed. In parallel to the occur rence of muscle injury, adaptative signs in the exercised muscles were found, such as enhanced collagen content and muscle fibers cross-sectional area. The great amount of chronic muscular damage in SOL and TA was not associated with the OTS in the short (1 week) and medium-term (3 weeks). Further, muscle damage demonstrated different behaviors according to the type of work that each muscle has performed, questioning the use of systemic markers of muscle damage as reliable methods to study the relationship between skeletal muscle damage and OTS.","PeriodicalId":104100,"journal":{"name":"Research & Investigations in Sports Medicine","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130856233","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}

The DD genotype is correlated with a higher risk of cardiovascular diseases, lower adaptability to hypoxic conditions, as well as lower cardio-respiratory capacity. The aim of the study was to examine the role of I/D polymorphisms in the ACE gene in surgical patients vs. healthy, active individuals. Two groups were investigated in the study: 91 surgical patients and 39 physically active controls. The level of adaptation to physical stress, compensating processes, and sense of well-being of participants were determined with subjective and objective inferential methods. Additionally, the repre-sented ACE gene polymorphism was evaluated using molecular analyses. The role of the DD vs. II genotype is unclear in healthy, active individuals. Whilst in patients who reg-ularly participated in sport accrued shorter hospital stay time (P = 0.04). The type of surgery performed significantly affects patients’ time to convalescence (P = 0.03). Patients’ time in hospital after oncological surgeries is longer, regardless of whether chemotherapy was received or not. Based on the collected data, it was not possible to indicate a common genotype predisposing resistance to physical stress in both examined groups, with no statistically significant correlation between the ID polymorphism of ACE gene in either group. However, the noted tendencies may suggest a role of allele I and II genotypes in patient convalescence and as such, necessitates further investigation.","PeriodicalId":104100,"journal":{"name":"Research & Investigations in Sports Medicine","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114460674","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}

Abstract In the era of big data, quantitative-based approach has become a very useful tool in neuroscience studies. Neural phenomena that occur at the level of the cerebral cortex generates electric activity that can be recorded using electroencephalography (EEG). We can divide into three macro areas, considering non-pathological studies in human movement, the suite of interesting topics as i) physical stimuli and body postures, ii) visual stimuli and experience, and iii) auditory stimuli and motor imagery. In this context, data analysis represents a fundamental core of tasks with the aim to extract accurate and consistent information. To facilitate the replicable identity, scientific research is therefore interested in developing statistical procedures of biological data analysis. The aim of this review is to explain the analytical workflow applied to the EEG signal. Through theoretical and practical feedback, this work will be useful for data scientists, neuroscientists, statistics, engineers or physiologists.","PeriodicalId":104100,"journal":{"name":"Research & Investigations in Sports Medicine","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129202899","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}

Interestingly preserving balance or body orientation while a voluntary movement is performed implies prediction of the postural disturbances provoked by the movement itself [1]. Indeed, limb or trunk movements induce a shift of body’s center of mass that can disturb balance if not compensated prior to their execution [2]. Such anticipated control of balance is grounded on the capacity of the brain to use a body internal representation (BIR) in space [3,4]. The BIR is built up and updated from multisensory integration involving proprioceptive, tactile, vestibular, visual inputs and is referred relative to a stable reference frame such as gravity. For example, the updating of the BIR through labyrinthine and muscle proprioceptive Ia inputs allows the fine tuning of the postural reactions following body disturbance [5]. It is worth noting that despite being important for calibrating proprioceptive inputs, visual information appears to be less involved than somatosensory for the fast updating of the body parts or whole-body position in space (i.e. BIR) required for enabling appropriate postural reactions. In this review, we will explore how the accuracy of the BIR can be improved by sensorimotor experience enabled by the practice of physical activities. We will particularly focus on activities that involve knowledge of the body parts’ relative motion and that require keeping or disrupting the vertical alignment of the body.","PeriodicalId":104100,"journal":{"name":"Research & Investigations in Sports Medicine","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128404721","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}

Due to the scarcity of the literature in regard to best practices, parameters for pre-scribing and applying cupping therapy is absent in competitive athletic population. To ensure appropri ate usage of cupping therapy, gaps in the literature on range of motion, strength, proprioception, power, speed and agility must be investigated. Therefore, the purpose of this study is to examine the effects of a single cupping therapy treatment to the gastrocnemius on Lower Quarter Y-Balance Test (YBT) scores in collegiate baseball players. Ten male (age 21.6 ± 1.90) collegiate baseball players participated in this study. Participants completed three attempts in the anterior, posterolateral, and posteromedial direc tions for both lower extremities per YBT procedures. Following baseline measurements, four plastic cups were applied to the gastrocnemius of the non-dominant lower extremity for 15-minutes. After treatment, follow up YBT scores were taken. Upon completion of data collection paired samples t-tests and one-way repeated measures ANOVAs were performed to determine significant differences in scores following cupping therapy. Significant improvements were found pre- and post-treatment in all three directions in the lower extremity receiving cupping therapy (p < 0.05). When compared with the control extremity, significant differences were found in the anterior and posteromedial directions (p < 0.05). These results suggest that a single cupping therapy treatment to the gastrocnemius may improve anterior and postero medial YBT scores in collegiate baseball players. Further studies are required to determine the effects of multiple cupping therapy treatments, as well as long term effects of cupping therapy on dynamic stability.","PeriodicalId":104100,"journal":{"name":"Research & Investigations in Sports Medicine","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131294911","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}
