Associations Between Early Specialization and Ice Hockey Goaltender Hip Kinematics: A Cross-sectional Study

OBJECTIVE: To compare hip kinematics between early specialized (ES) and not early specialized (NES) ice hockey goaltenders. DESIGN: Cross-sectional study. METHODS: Twenty-six goaltenders’ (13 ES) kinematics were quantified during common goaltending tasks (ie, butterfly drops, power and butterfly slides) performed on a slide board using Theia3D markerless technology. Maximum and minimum hip flexion, adduction, and internal rotation (IR) angles were determined, as were the concurrent hip angles in the two other planes at these positions. The groups were compared using independent t tests or Mann-Whitney U tests for discrete data and statistical parametric mapping for hip angles over time. RESULTS: ES goaltenders had increased IR and abduction at lower flexion and less IR and abduction at higher flexion compared to NES goaltenders. Neither group reached the expected extreme ranges of flexion, adduction, or IR typically associated with mechanical bony impingement of femoroacetabular impingement syndrome (FAIS). CONCLUSION: The ES goaltenders may minimize combined flexion and IR or abduction to avoid pain in hips due to FAIS or labral tears or have adopted advantageous hip control strategies to avoid abnormal hip contact mechanics that contribute to developing these pathologies.

Assessment of the Ergonomic Exposures for Home Healthcare Workers in the United Kingdom

Home healthcare has been identified amongst the most hazardous industries in healthcare. Many of the tasks being conducted by home healthcare workers are associated with significant demands including physical demands such as mobility and repositioning activities as well as psychological demands which is attributed by dealing with a complex environment whilst administering medical and life saving care to patients, and social demands that encompasses dealing with dying and grieving patients. With the homes in United Kingdom having potentially unique exposures due to the healthcare system and design of the homes such as multi-floors, smaller condensed rooms, and limited ventilation, the purpose of this study was to investigate the exposures for home healthcare workers in the United Kingdom. Ergonomic hazards were observed through various tasks such as repositioning in bed (34.8%), transfer from bed to chair (30.4%), transfer from bed to chair (26.1%), and transfer from chair to chair (26.1%) and particularly for nursing aides. Lifting hoists were only used 13 times (19%) and predominantly by nursing aides (12 of 13, 92%). A slip sheet or slide board was used 7 times (10.1%), all being nursing aides using them.

Effect of an Eight-week Slide Board Exercise Program on Functional Performance of Female Basketball Players With Chronic Ankle Instability

Background and Aims Ankle sprain is the most common lower limb musculoskeletal injury in athletes, which can be improved with low-cost and non-invasive rehabilitation programs. The present study aimed to determine the effect of eight weeks of slide board exercises on the center of pressure (COP) displacement, ankle proprioception, and ankle muscle strength of female basketball players with chronic ankle instability (CAI). Methods This is quasi-experimental with a pre-test/post-test design. Participants were 28 professional female basketball players with CAI, who were randomly divided into two groups: Exercise (age:14.00±0.78 years, height: 167.78±6.45 cm, weight: 59.57±7.18 kg) and control (age:14.07±0.82 years, height: 167.08±3.85 years, weight: 62.92±3.45 kg). Before and after the training period, the variables of COP displacement (using a foot scan device), ankle proprioception and ankle muscle strength (using Biodex system 3 pro) were measured. The exercise group performed the slide board exercises for 8 weeks, three sessions per week, each for 60 minutes under the supervision of the examiner. For statistical analysis, the analysis of covariance test was used. The significance level was set at 0.05. Results The results showed a significant difference in COP displacement (P≤0.001), ankle proprioception (P≤0.001), and ankle muscle strength (P≤0.001) after exercises between the two groups, and confirmed the higher effectiveness of the slide board exercises. Conclusion The slide board exercises for eight weeks can reduce the COP displacement and ankle proprioception and improve ankle muscle strength in professional female basketball players with CAI. Therefore, slide board exercises are recommended for the rehabilitation of female athletes with CAI.

Interval training using a slide board is superior to cycloergometer regarding aerobic capacity and specific fitness in elite ice hockey players

Introduction: Ice hockey is a physically demanding sport that requires a combination of aerobic and anaerobic capacities, as well as specific on-ice skills. This study aimed to compare the effectiveness of individualized interval training on a slide board with training on a cyclo-ergometer, focusing on aerobic capacity and specific fitness in elite ice hockey players. Materials and Methods: Thirty players were randomly divided into an experimental (slide board) and a control (cyclo-ergometer) group. Both groups underwent a 6-week training program with the same intensity and volume. Results: The results showed that both forms of training led to significant improvements in aerobic capacity, as indicated by VO2max and VO2 lactate thresholds. The slide board training group demonstrated higher effect sizes (d = 1.49, 1.62) than the cyclo-ergometer one (0.76, 0.43). Specific on-ice performance tests showed that slide board training resulted in faster skating times (p = 0.0002), suggesting a greater transfer of training effects to on-ice skills. Conclusions: This study highlights the benefits of incorporating slide board interval training into the off-season training regimen of elite ice hockey players. Slide board training improves specific on-ice skills, which are crucial for high-level hockey performance. These findings provide valuable insights for coaches and strength and conditioning specialists working with elite ice hockey players.

Biomechanical stresses on healthcare workers during manual patient bed-to-chair transfers

Healthcare workers are highly susceptible to musculoskeletal injury, particularly in their lower back and shoulders. Manual patient transfers are common and can generate physical stresses that contribute to these injuries. Few studies have used in vivo musculoskeletal modeling to estimate the effect of slide boards and patient cooperation, and none have used measured hand forces as an input to the models. This laboratory study evaluated manual, one-person bed to wheelchair transfers of a 64 kg simulated patient using an instrumented gait belt that measured hand forces. Thirteen healthcare workers performed transfers with and without a slide board and with up to three levels of vertical assistance (0, 18, and 36% of patient body weight). In vivo lower back forces and resultant shoulder moments were estimated with a thoracolumbar musculoskeletal model using directly measured hand forces and full-body motion capture. Results indicated that slide boards and vertical assistance reduce physical stresses. However, all transfer conditions had trials that exceeded an ergonomic guideline. To provide some guidance on when a transfer can safely be performed manually, a post hoc analysis was performed to estimate the patient mass that can be safely transferred manually under ideal circumstances with only a gait belt. These findings have the potential to guide and credibly educate healthcare workers on when manual transfers are appropriate and when lifts are required. Regardless, mechanical lifts are still recommended in most circumstances to protect caregivers from injury and the patient from falling.

Effects of Adding Mechanical Vibration and a Stick on Acceleration and Movement Variability during a Slide-Board Skating Exercise: Differences between the Dominant and Non-Dominant Legs

The aim of the present study was to analyse differences in acceleration and movement variability caused by adding whole-body vibration (WBV) and an implement (stick) while performing a slide-board (SB) skating exercise. A total of 10 professional ice-hockey players (age 20.4 ± 2.07 years) participated in the study. Participants performed 30 s of lateral sliding on a slide vibration board (SVB). Four conditions were analysed: no vibration and no stick (NVNS), no vibration with a stick (NVS), vibration without a stick (VNS) and vibration with a stick (VS). Peak acceleration, mean acceleration and movement variability (MV) were analysed in the dominant and non-dominant legs in each condition. Peak acceleration was higher in the non-dominant leg (p < 0.01). However, MV was higher in the dominant leg (p < 0.01). Regarding differences between conditions, mean acceleration was higher in VNS and VS than in NVS (p < 0.05). Regarding MV (sample entropy), there were differences in NVNS compared to VNS and VS (p < 0.01) and in NVS compared to VNS and VS (p < 0.01), with the values being superior in VNS and VS. The addition of WBV during an SB skating exercise results in an increase in MV and mean acceleration. The dominant leg shows greater MV regardless of the addition of vibration and a stick during sliding on an SVB.

Effects of Mechanical Vibration during an Incremental Slide Board Skating Test on Physiological and Movement Variability Parameters

The physiological, kinematic, and performance benefits of slide board (SB) training are well established. However, there is limited research investigating the potential effects offered by combining SB training with whole-body vibration (WBV). This study aimed to evaluate the impact of WBV on movement variability (MV) and physiological parameters during an incremental SB skating test. Ten elite ice hockey players (20.4 ± 2.07 years; 1.79 ± 0.05 m; 75.97 ± 5.44 kg; 23.64 ± 1.64 body mass index) participated in this study. An incremental test was conducted on the SB under two conditions, randomized in order: WBV (30 Hz) and non-WBV (0 Hz). The incremental test rhythms were established at 30, 35, 40, and 45 Hz. Participants performed the exercise on the SB at each rhythm for four minutes, for a total of 16 mins. MV, subjective perception of effort (RPE), heart rate (HR), and ergospirometric parameters were assessed. Differences were observed between rhythms in ergospirometric parameters and HR, increasing directly with rhythm (p < 0.05). Regarding differences between conditions, MV was higher when the incremental test was performed with WBV (p < 0.01). The addition of WBV during SB training resulted in a rise in MV without affecting physiological parameters.

The Influence of the Presence or Absence of a Patient Transfer Slide Board on Radiation and Image Quality When Using an Automatic Tube Current Modulation with Bed Height Compensation

The purpose of this study was to evaluate the effect of patient transfer slide boards with automatic couch height positioning compensation (AHC) on image quality and radiation dose during computed tomography (CT) examinations. The chest phantom for Kyoto Kagaku (Kyoto) Type PBU-SS 2 was performed helical scan using a Canon Medical Systems (Tochigi) 80-row CT Aquilion Prime SP/i Edition. Scan parameters were tube voltage: 120 kV, tube current: min 50 mA max 500 mA with AHC for noise index: 15, slice thickness: 5.0 mm, rotation time: 0.35 s/rotation, pitch factor: 0.813, reconstruction kernel: FC03. Filtered back projection was used for image reconstruction. We compared the image noise and volume computed tomography dose index (CTDIvol) displayed on the console with and without the patient transfer slide boards by using or not using the AHC. When using the AHC, CTDIvol was increased (p<0.05), and image noise was decreased (p<0.05). Without the AHC, there was no significant difference in CTDIvol (p=0.11) and image noise (p=0.29). The slide board utilized in this experiment did not have a notable impact on either image quality or exposure dose. Nonetheless, the use of the slide board was found to result in excessive exposure during CT scans that employed AHC.

Determining push-off forces in speed skating imitation drills

Speed skating takes place on ice rinks and is, therefore, dependent on seasonal conditions. To be able to train all year round, training in the summer months, when no ice rinks are available, consists mainly of athletics and endurance training as well as imitation drills. Imitation drills are exercises, e.g. on a slide board, which imitate the actual skating movement. To objectively evaluate the quality of the execution of these exercises, key performance indicators such as push-off forces need to be quantified. The aim of this work was to determine the push-off forces during speed skating imitation drills using pressure insoles in combination with machine-learning methods. A slide board is usually not instrumented. Here, the slide board was equipped with force plates to record the target variables, i.e. the push-off forces. The input variables to determine the push-off forces were recorded using plantar pressure insoles and triaxial accelerometers. Seven participants took part in the study. Two different machine-learning algorithms were compared. A non-linear deep neural network model and a linear multiple variable regression model. The models were trained using the obtained force–time curves. The linear regression model proved sufficient to predict the push-off forces. The relative difference between the measured and modelled maximum push-off force remained below 5%. This approach, based on a mobile and low-cost measurement system, allows a quantitative analysis of the athlete’s technique/performance. Therefore, we expect the instrument to be a helpful tool for the training of speed skaters.

Reliability of Alpine Ski Racing-Specific Field Test: The 80s-Slide-Test.

The purpose of this study was to determine the test-retest reliability of the 80s-slide-test in well-trained alpine ski racers. The sample consisted of 8 well-trained alpine ski racers (age = 17.8 [0.7]y old; height = 1.80 [0.09]m; body mass = 72.1 [9.5]kg) who performed a lab-based maximal graded test on cycle ergometer and three 80s-slide-tests in 4 separate sessions. The 80s-slide-test consisting of maximal push-offs performed for 80s on a 8-ft slide board. Oxygen uptake (V˙O2) and heart rate (HR) were recorded continuously. Blood lactate ([La]b) was determined immediately prerun, followed by 3minutes postrun. Three minutes after the completion of the session, the subjects were asked to indicate their rate of perceived exertion using Borg scale ranging from 6 to 20. Total and every 10s mean push-offs number were assessed by camera. Typical errors of measurement, intraclass correlation coefficients, and smallest worthwhile change were calculated. The 80s-slide-test showed strong reliability for total push-offs number, V˙O2peak, V˙O2mean, HRpeak, and HRmean. Δ[La]b, fatigue index, and the rate of perceived exertion were moderately reliable. The 80s-slide-test is a reliable test for well-trained alpine ski racers and can be used easily by trainers.

BALL KICKING BIOELECTRIC ACTIVITY OF MUSCLES IN STUDENTS PLAYING SNOW FOOTBALL

Aim. The article aims to explore the features of a ball kicking bioelectric activity of lower limbs muscles in students playing snow football. Materials and methods. 30 males aged 21–25 years old were examined (3–4-year students): the control group consisted of 15 people playing football; the main group included 15 people playing snow football. Athletes kick a ball on a normal and on a slippery surface, imitation of a slippery surface was carried out using a GYMSTICK Power Slider 61131-PRO slide board. To record the bioelectric activity of the muscles, the Neuro-MVP-4 multifunctional computer system was used (Neurosoft, Ivanovo, Russia). The bioelectric activity of the calf muscles (the medial lateral head of the calf muscle), the rectus femoris muscle, and the adductor longus muscle was studied. Results: It has been shown that athletes playing football and snow football have different and largely opposite motor stereotypes of intermuscular coordination when kicking the ball in usual conditions. When this action is repeated under unusual conditions, stereotype distortion is observed. Football players are characterized by a partial stereotype distortion, while people playing snow football are almost completely disorganized on a normal surface. Conclusion: Football training for students playing various types of football should be carried out in different conditions and implement various strategies. In particular, it should be aimed at various muscle groups. Ball kicking in unusual conditions should be used carefully, as this can be accompanied by a negative transfer of skills and reduce the effectiveness of athletes’ performance.

PHYSICAL PREPARATION FOR ICE HOCKEY WITH UNTRADITIONAL MEANS

The data from empirical researches in sport training methodology show that leading factors, which define hockey player’s special physical preparation is a strength and aerobic capacity of muscles groups that realize movement on ice. Aim of the research: improvement of physical preparation training process in ice hockey, using “Slide board” equipment. Subjects of the research: youth age group (U17) of the ice hockey team who were implemented eight modified “Slide board” exercises in the training process during 8 weeks. The results of experimental group show significant improvement (α&lt;0.05) in “Acceleration and breaking skating 5x54m” test. Using routine of exercises with “Slide Board” equipment and applying repetition method during overall physical preparation period time, experimental group participants had been achieved an effective increase in special strength endurance than control group, which used training program based on previous season exercises and applied circle training after interval extensive method.

Validity of different EMG analysis methods to identify aerobic and anaerobic thresholds in speed skaters

Purpose: This study aimed to assess the validity of the first (EMGth1) and second (EMGth2) breakpoints in the EMG signal during skating. Scope: Ten well-trained long track speed skaters performed a maximal incremental skating test on a slide board. EMG signals from six lower limb muscles were recorded during the last 15 s of each stage and converted to Root Mean Square for determination EMGth1 and EMGth2 using mathematical (2 and 3 linear regressions) and visual methods. Conclusions: EMGth1 had a low detection rate (<50%) while EMGth2 could be identified visually in > 80% of cases, in 85% of cases using 2-lines and 63% using 3-lines regression. Quads (VL + VM) and Gluts (GM + GMd) had the highest EMGth2 detection rate for all methods (>70%). EMGth2 from Quads and Gluts detected by the 2-lines and 3-lines regression were not different than the second ventilatory threshold (VT2) (p > 0.05), while the visual method overestimated VT2 (p < 0.01). EMGth2 detected from Quads by the 2-lines regression method presented better correlation with VT2 stage (r = 0.91), lowest bias, and limit of agreement. We conclude that EMG is a valid non-invasive method to detect VT2 during skating when using a mathematical method to determine EMGth2.

An ergonomic assessment of using laterally-tilting operating room tables and friction reducing devices for patient lateral transfers

Patient lateral transfers between two adjacent surfaces pose high musculoskeletal disorder risks for nurses and patient handlers. The purpose of this research was to examine the ergonomic benefits of utilizing the laterally-tilting function of operating room (OR) tables during such transfers – along with different friction-reducing devices (FRD). This method allows the patient to slide down to the adjacent surface as one nurse guides the transfer and another controls the OR table angle with a remote control. Sixteen nursing students and sixteen college students were recruited to act as nurses and patients, respectively. Two OR table angles were examined: flat and tilted. Three FRD conditions were considered: a standard blanket sheet, a plastic bag, and a slide board. Electromyography (EMG) activities were measured bilaterally from the posterior deltoids, upper trapezii, latissimus dorsi, and lumbar erector spinae muscles. The Borg-CR10 scale was used for participants to rate their perceived physical exertions. The efficiency of each method was measured using a stopwatch. Results showed that the tilted table technique completely replaced the physical efforts that would have been exerted by the pushing-nurse, in that muscle activation did not increase in the pulling-nurse. On the contrary, EMG activities of the pulling-nurse for most of the muscles significantly decreased (p < 0.05). The subjective Borg-ratings also favored the tilted table with significantly lower ratings. However, the tilted table required on average 7.22 s more than the flat table to complete the transfer (p < 0.05). The slide board and plastic bag were associated with significantly lower Borg-ratings and EMG activities for most muscles than blanket sheet, but they both were not significantly different from each other. However, they each required approximately 5 s more than the blanket sheet method to complete the patient transfer (p < 0.05). By switching from flat + blanket sheet to tilted + slide board, EMG activities in all muscles decreased in the range of 18.4–72.3%, and Borg-ratings decreased from about 4 (somewhat difficult) to 1 (very light). The findings of this study propose simple, readily available ergonomic interventions for performing patient lateral transfers that can have significant implications for nurses’ wellbeing and efficiency.
