The participants’ anthropometric traits and body composition parameters were determined with the InBody analyser. Based on the students’ physiological parameters, the effectiveness of various types of PA was measured with Suunto. Ambit3 peak heart rate monitors during 60 minutes of physical exertion. The average values of body mass, body mass index (BMI), body fat mass (BFM), percent body fat (PBF), waist hip ratio (WHR), and visceral fat (VFL) were significantly (p<0.05) lower in students who performed jogging, followed by sauna (JFBS) and martial arts than in the remaining PA groups. Minutes of difficult and very difficult intensities were highest in martial art students, followed by jogging students, and they were significantly (p<0.05) higher than the values noted in the remaining PA groups (golf, bodybuilding/fitness, swimming, general PE classes, cycling and individual training). Physiological parameters were significantly (p<0.05) lowest in golf players and students who trained individually. Martial arts and JFBS are the most effective types of PA among male university students. Students performing martial arts and JFBS were characterized by the lowest relative, body fat, whereas students who practiced swimming had the highest body fat levels in the population sample.","PeriodicalId":42772,"journal":{"name":"Acta Kinesiologica","volume":"49 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70783457","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}

Many authors assume that about 80% of the population over forty have at least one major episode of pain in the lumbar area. Many of those patients demonstrate lumbosacral radicular symptoms. Sciatica usually develop as a result of a disc-root conflict and can disturb patients posture and balance. The objective of this study was to assess the effect of the visual biofeedback balance control training in patients suffering from sciatica on posture and balance. This was a randomized clinical study with control group, single-blind. Sixty suffering from sciatica patients (54% females) in the age between 20 and 83 met the inclusion and exclusion criteria. In the experimental group (VBF) in addition to comprehensive rehabilitation, visual feedback balance training was used. In the control group (KT) except comprehensive rehabilitation the kinesiology taping was applied within the lumbar region. For outcome measure center of foot pressure deflection, execution time, Bohannon's standing one-leg test, distribution of limb loads, Functional Ambulatory Category, Timed Up and Go, lumbar spine mobility, Laségue symptom, neurological symptom examination and the Visual Analog Scale has been used. In results: visual feedback balance control training using the balance platform had a statistically significant impact on execution time, standing on one leg, spine mobility, gait, coordination and pain. Dynamic kinesiotaping had a statistically significant effect on COP sway, balance, gait, coordination and pain. Feedback balance control training was more beneficial than dynamic kinesiotaping, although not statistically significant. In the VBF group no statistically significant effects on COP sway and distribution of limb loads has been observed. No effects of gender, side of sciatica (left/right) nor BMI has been observed. Statistically significant effect of visual feedback balance control training was observed in both groups in the age below 55.

Players are allocated into one out of eight class. In the past, the map of the volume of action for each class player was created based on classifiers’ experience and knowledge (in qualitative way, without the range of trunk movement). Based on Paralympics’ classification standards there is a need to provide quantitative data for the current classes. The aim of this study was to create the map and reference values of the volume of trunk action of wheelchair basketball players and to check if there are differences in results between players representing different functional classes. The second aim was to investigate if there are significant benefits of using additional equipment with the sport wheelchair like sports straps that help players to achieve the greater volume of trunk action. Sixty-eight players divided into functional classes were asked to perform the maximum active trunk range of movement in three planes, in a sport wheelchair with straps and without straps, that was measured by the Kinect for Windows V2 sensor. The differences in movement was assessed by the t-test or the Wilcoxon test, differences between classes were done by ANOVA and the post hoc Tukey test. The discriminant analysis was calculated. Significant greater volume of trunk action in each plane was noticed in a sport wheelchair with straps (p < .05). There were observed significant differences in trunk movement in three planes between neighboring classes (p < .05). 76.9% original grouped cases were correctly classified. The accuracy of the current classification system in wheelchair basketball was confirmed. The map and reference values of the volume of trunk action will be helpful for all wheelchair basketball stakeholders. Trunk flexion and rotation discriminate the most effectively players. All class players should use appropriately fitted straps around hips during wheelchair basketball game, for safeness and wider volume of action.","PeriodicalId":42772,"journal":{"name":"Acta Kinesiologica","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70783708","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}

This fact comes as a result of cooperation of football players during a match, which requires anticipation and making right decisions. The process of intellectual training is often outlined by coaches, but in a regular training it is often not discussed in detail, since not many studies confirmed its importance. In the paper the level of thinking of players during cooperation in scoring a goal was discussed as well as modeling of the game using means of intellectual training. The observation of player cooperation included the analysis of 141 goals scored in 76 randomly selected football matches in UEFA Champions League from 2005 to 2019. In the study the method of noted observation was used, the subject of the study could be observed many times. The actions were observed due to the level of thinking processes. The analysis of the results shows that cooperation of the players in order to achieve the ultimate offensive objective of the game requires intentional actions based on thought patterns. These patterns taught in the training can guarantee not only anticipating in the realization of common tasks, but also making decisions that are best for the effectiveness of the game.","PeriodicalId":42772,"journal":{"name":"Acta Kinesiologica","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70783960","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 training process is conditioned by the rank and level of competition and its implementation largely depends on the education of professional staff. Common mechanisms of injury are pressure, sprain, strain, ischemia, and sports injury. Seddon's original system of dividing nerve injuries based on neurophysiological changes is most widely used in medicine. The initial stage of nerve injury is neuropraxia, the second stage is axonal degeneration, and the third stage is nerve cutting. Peripheral nerve injuries are more common in the upper extremities than in the lower extremities. They have specifics related to a particular sport, in this case, football and basketball, and often have a biomechanical component in the making. Early detection allows an appropriate rehabilitation program to be initiated and biomechanics changed before the nerve injury becomes permanent. Recognizing nerve injury requires an understanding of peripheral neuroanatomy, knowledge of common nerve injury sites, and awareness of the types of peripheral nerve injuries that are common and specific to a particular sport. Rehabilitation programs in the field of kinesiology can be read through FMS protocols. Electrodiagnostic tests (electromyography), somatosensory evoked potentials, magnetic resonance imaging, and ultrasound are used to diagnose peripheral nerve injuries. Proximal peripheral nerve injuries have a slightly poorer prognosis in terms of neurological recovery in athletes. The survey determined the frequency of injuries in the subjects and that there is a misunderstanding among the athletes themselves, which is a peripheral nerve injury. The survey also found that peripheral nerve injuries occur due to acute injuries, while chronic injuries are excessive, resulting in damage to muscles and joints, and rarely as a result of inappropriate sports equipment. Athletes' knowledge of what constitutes a peripheral nerve injury itself and how this type of injury should be given more importance in further general prevention has also been established.","PeriodicalId":42772,"journal":{"name":"Acta Kinesiologica","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70783385","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}

Muscle activation with resistance band exercises is believed to improve positional control of the pelvis and the lower limbs, thus reducing the risk of musculoskeletal injury during rehabilitation or training proper. The aim of this study was to assess the impact of a single session of activation of hip joint abductors and external rotators on gait and running parameters in healthy people. The study involved 54 healthy individuals aged 19-21 years. An experimental group (Group 1) performed a set of 6 resistance exercises with Thera rubber bands, intended to activate the hip joint abductors and external rotators. A control group (Group 2) performed the same set of exercises but without external resistance. A walking and running gait examination was performed on a Zebris FDM treadmill in both groups before and after the exercises. Both variants of exercises produced changes in selected gait parameters (p<0.05). An examination of running gait in Group 1 revealed an increase in step length in the dominant limb (p<0.05) and stride length (p<0.05) and step time in the dominant limb (p<0.05), stride length (p<0.05) and cadence (p<0.05). Heel pressure also decreased in both limbs, and heel pressure force decreased in the non-dominant limb (p<0.05). A running gait examination in Group 2 revealed increased midfoot pressure force in both limbs (p<0.05). Thus, a single session of exercises with resistance banding to activate the hip joint abductors and external rotators exerted an effect on running parameters, which may improve running economy.","PeriodicalId":42772,"journal":{"name":"Acta Kinesiologica","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70783781","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}
