In North America ice hockey is considered to be the fastest of all teamsports with high demands on leg strength and power. These two factors are crucial for acceleration and the total speed performance during a hockeygame. Skating performance requires a muscle engagement which also occurs during the Y-Balance Test (YBT). Some of the most active muscles during ice skating are biceps femoris, tibialis anterior and vastus medialis , these muscles are also some of the most active muscles during the YBT. The similarities between those two activities enable a possible relationship between skating velocity and YBT. This study investigated the relationship between dynamic postural control and on ice performance which includes 52 meter forward skating. The purpose of this study was to see if there is a significant correlation between skating velocity and the performance on YBT. Methods: 7 male ice hockey players in ages between 18-19 years performed a 52 meter forward skating test and a test for evaluating their dynamic postural control. The method used for measuring the dynamic postural control was the YBT. Results: There was no significant correlation between the YBT longitudinal directions, the total score and 52 meter forward skating. The strongest association (0,570) was shown between the YBT anterior longitudinal direction and 52 meter forward skating. The total score on YBT did not show a significant correlation with 52 meter forward skating, with a correlationcoefficient of 0,251. Conclusion: Due to several management errors during the YBT the results showed no significance. We can not for certain say that there is no significant correlation due to for instance management errors and the deficiency pf power. Future studies are needed to determine if there is a significant correlation between skating velocity and the performance on YBT.

Title: Effect of fitness concept FLOWIN® on balance and spinal segmental stabilisation Objectives: The goal of this thesis is to find out whether exercising the fitness concept FLOWIN® has any real and measurable effect on balance and spinal segmental stabilization of the individual, based on the comparison of measured data of exercisers of different levels of profficiency, which is differentiated by the length of exercise (beginners, advanced) and instructors of group lessons operating in the Czech Republic. Methods: The study in nature was a blinded experiment, attended by 13 beginners, 19 advanced exercisers and 10 instructors of the fitness concept FLOWIN®. Each participant's balance was tested by using the Y Balance test on lower and upper body and testing of spinal segmental stabilization was performed by using tests based on the principles of Australian method.

PURPOSE/BACKGROUND: Muscle fatigue is related to a decline in force output and proprioception. These can ultimately have an adverse effect on neuromuscular control and functional performance. Local muscle fatigue has been shown to have adverse consequences on dynamic standing balance; however, much less is known regarding the relationship between distant fatigue and dynamic standing. The purpose of this study was to investigate the effects of upper body fatigue on dynamic standing balance. It was hypothesized that distant fatigue in upper body musculature would show a significant decrease in dynamic standing balance as assessed by the Lower Quarter Y-Balance Test (YBT-LQ). METHODS: TWENTY HEALTHY INDIVIDUALS (AGE: 25.0 ± 3.42 years, height: 172.72 ± 13.11 cm, mass: 71.36 ± 13.50 kg) participated in this study. A kayak ergometer was used to implement a fatigue protocol for the upper body. The protocol consisted of a graded intensity session ranging from 50% to 90% of maximum effort lasting ten minutes in duration (2 minutes each at 50% 60%, 70%, 80%, and 90%). The anterior (ANT), posteromedial (PM), and posterolateral (PL) reach directions were normalized to leg length and measured on the YBT-LQ before and after the fatigue protocol for each participant. A fourth value termed overall balance was calculated as the sum of the furthest reach distance of the three directions. Blood lactate analysis taken before and immediately after the fatigue protocol was used to quantify fatigue. Multiple paired t-tests were performed for pre-fatigue and post-fatigue balance assessment. A Bonferroni correction was applied to set the significance value ≤0.0125 a priori. Effect size was calculated using the effect size index. RESULTS: Blood lactate values immediately following the fatigue protocol had an average concentration of 6.15 millimoles (pre: 2.3, post: 8.4). The ANT reach direction (ρ = 0.004) and the calculated overall balance (ρ = 0.011) significantly decreased post-fatigue in the dominant lower extremity. No significant differences were found for the PM (ρ = 0.017) or PL (ρ = 0.021) directions. The ANT reach direction (0.64) and overall balance (0.44) also showed a moderate effect size based on the effect size index. CONCLUSIONS: ANT and overall dynamic standing balance were negatively affected after completing the upper body fatigue protocol. The findings of this research demonstrate that upper body fatigue has adverse effects on dynamic standing balance, as measured by performance on the YBT-LQ. Significant and clinically relevant differences were noted in ANT and overall dynamic standing balance. CLINICAL RELEVANCE: Physical therapists should be aware of the adverse influence distant fatigue may exhibit on neuromuscular control in muscles not actively involved in the fatiguing exercise. The balance deficits noted may indicate an increased risk of injury with muscle fatigue in muscles not directly contributing to standing balance. LEVEL OF EVIDENCE: 3b, Case-control study.

Background: Basketball is one of the most popular physical activities in the world and lower limb joints are constantly exposed to physical stress. Girls have been shown to perform athletic movement with an adverse biomechanical profile with high risk for injury. We need more knowledge about how we can introduce motion control training in their regular training program in a simple and uncomplicated way. This study aims to examine the effect and experience of a preventive biomechanics program for female adolescent basketball players. Method: Twelve female basketball players, 12-13 years old, participated in this uncontrolled pilot intervention study. The seven weeks intervention included a 12 minutes preventive biomechanics program twice a week and a daily 2 minutes homes exercise. Performance on the Y-Balance test (YBT), a motor control test battery (MCTB) and hip abductor strength (HAS) was assessed before and after the intervention. Their experience was evaluated using a questionnaire after the intervention. Result: The participants improved significantly in all three outcome measures, YBT, MCTB and HAS after completed intervention. All participants indicated in the questionnaire that they were positive about the intervention and that they would choose to participate again. Conclusion: A seven week preventive biomechanics program twice a week showed positive effects on both motor control exercises and subjective experience among female adolescent basketball players. These results indicate that the training intervention was well accepted and had positive effects on balance, trunk motor control and hip muscle strength. This may in turn have positive effect on injury prevention. However, that needs to be investigated in future RCT with longer follow up time.

Title: The effect of compensatory exercises in ice hockey players of younger school age with focus on the evaluation of selected parameters of stability, coordination and movement stereotypes Objectives: The objective of this thesis was to verify the effect of compensatory exercises on stability, coordination and movement stereotypes in ice-hockey players of younger school age (8-12 years old). Specifically, the objective was to verify stated effect on dynamic stability, static stability of the trunk, execution of selected stereotypes, coordination and performance in specific test on ice. Methods: Data for this thesis were collected using quantitative form of research. The whole research population was composed of 75 probands with the average age of 10,3 years and who play actively ice-hockey. The population was composed of both sexes, males and females (boys and girls). Participants were divided into two groups - experimental (n = 43) and control (n = 32). To collect the values of measurements was used method of testing with clinical tests and to eliminate disturbing elements we also used the method of questionnaire. The values were collected in input and output sessions. The time spacing between those two measurements was 3 months. Between stated two measurements in experimental group took place...

Bakgrund: Medvetenhet om kropp och rörelse nämns ofta som en viktig fakor i att öka prestationsförmåga, undvika skador, nå högre livskvalitet och förbätta sjukdomstillstånd. Det har länge funnits ambitioner att förbättra rörelse genom ökad medvetenhet. Feldenkraismetoden är en metod för att förbättra rörelse genom förhöjd rörelsemedvetenhet och är förenlig med nutida vetenskap men förhållandevis lite empirisk forskning stöder metodens effektivitet. De flesta tidigare studier har varit på någon form av dysfunktion och ofta subjektiv upplevelse snarare än objektiva värden. Det har varit svårt för Feldenkraispedagoger att finna rätt mätmetoder för att utvärdera metoden. Syfte: Studiens syfte är att utvärdera effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på rörelse hos friska personer genom kvantitativ mätning. Metod: Friska kvinnor i en experimentgrupp (n=4, 30±7 år) och en kontrollgrupp (n=4, 26±2 år) testades med fem kvantitativa rörelsetester; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test och upper quarter Y-balance test, innan och efter en intervention ledd av en auktoriserad Feldenkraispedagog där experimentgruppen genomgick tio träningsfällen enligt Feldenkraismetoden under fem veckors tid. Resultat: Signifikant förbättring (P≤0,05) i förhållande till både förtest och kontrollgrupp sågs vid star excursion balance test för vänster ben. Slutsats: Träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden verkar kunna leda till förbättring i kvantitativt mätt rörelse hos friska kvinnor. Vidare forskning med fler deltagare är nödvändig för att bättre besvara hypotesen att träning för ökad rörelsemedvetenhet genom en intervention med Feldenkraismetoden leder till förbättrade resultat i de utvalda testerna hos friska personer. / Background: Awareness of body and movement is often mentioned as an important factor in increasing performance ability, avoiding injury, reaching a higher quality of life and improving conditions of illness. There has long been an ambition to improve movement through increased awareness. The Feldenkrais method is a method for improving movement through increased movement-awareness and is compatible with modern science. but comparatively little empirical research supports the methods effectivity. Most earlier studies have been on subjects with some form of dysfunction and often on subjective experience rather than objective measurements. It has been challenging for Feldenkrais-practitioners to find suitable ways of measurement for evaluating the method. Purpose: The purpose of this study is to evaluate the effect of training for increased movement-awareness according to the Feldenkrais method on movement in healthy subjects by quantitative measurements. Method: Healthy women in an experiment-group (n=4, 30±7 years) and a control-group (n=4, 26±2 years) were tested with five quantitative movement-tests; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test and upper quarter Y-balance test, before and after an intervention where the experiment-group went through ten training sessions according to the Feldenkrais method during five weeks time. Results: Significant improvement (P≤0,05) in comparison to both pre-test and change in the control-group was seen for star excursion balance test of the left leg. Conclusion: Training for increased movement-awareness according to the Feldenkrais method seem to be able to improve quantitatively measured movement in healthy women. Further research with more participants is necessary to better answer the hypothesis that training for increased movement-awareness in accordance with the Feldenkrais method leads to improved results in the chosen tests in healthy persons.
