Supercapacitors Serving as Power Supply in Tiny Sport Sensors - Field Testing Through Heart Rate Monitoring in Endurance Trail Runs

Authors:

Hans Weghorn

Abstract: In professional and in non-elite sport activities, people today are using various electronic monitoring tools quite commonly. Sportspersons often are embedded into a personal body sensor network, which traces different parameters of their physiological activity. Especially heart rate sensors are used broadly, but often all kinds of meters, e.g., for counting foot steps and pedal turning, are also utilized in parallel. As technical construction, it has commonly established that these sensor devices are autonomously operated as very tiny computer systems from built-in lithium battery cells. Replacing such sensor batteries from time to time is expensive, the mechanical handling of this process is not very easy due to the small sensor housings, and it has to be reminded that use of throwaway batteries represents a waste of resources. In this work, an alternative power supply for sports sensors is investigated, which bases on the use of so-called supercapacitors. Construction concepts, advantages of the approach related to handling and manufacturing, and the possible application ranges are thoroughly discussed, while the study is complemented with practical experiments from endurance running sports.

Numerical Comparison between a Modern Surfboard and an Alaia Board using Computational Fluid Dynamics (CFD)

Authors:

Luca Oggiano

Abstract: Surfboard design is traditionally considered more as an art than an engineering process. However, in the past decade, the use of computers is becoming the standard in the shaping process. In the design part the use of computer-aid-design (CAD) software, has simplified the design process allowing shapers to save time and consistently modify or reproduce similar designs. At the same time, the improvement of computer-numerical-controlled (CNC) machines is slowly replacing the traditional hand shaping techniques with more controlled and reproducible manufacturing process. Another considerable advantage about having a 3D CAD model of the surfboard is that the model can be imported in Computational Fluid Dynamics (CFD) programs and its performances can be studied and evaluated highlighting details that would be otherwise impossible to identify from a field test. The present paper aims to show the potential of CFD solvers for surfboard design and its applicability by comparing a modern surfboard with a traditional ancient surfboard design (alaia). The performances of the modern surfboard are evaluated and compared with the alaia board, represented by an equivalent flat plate which is also used for validation. The commercial CFD code STAR-CCM+ is used in the present work. An Unsteady Reynolds Navier Stokes (URANS) approach is used, the volume of fluid (VOF) method is chosen as free surface discretization method and the turbulence model chosen to allow the numerical closure of the RANS equations is the k-ɷ-SST proposed by Menter. The model validation on an alaia board, represented as a flat plate shows good agreement with previous studies and the comparison between the surfboard and the alaia addresses the superiority of the modern surfboard design in terms of stability.

Authors:

Tomasz Krzeszowski, Krzysztof Przednowek, Krzysztof Wiktorowicz and Janusz Iskra

Abstract: This initial research is a case study that uses a multiview human body tracking method as a tool to measure hurdle clearance kinematic parameters. This study is conducted on a hurdler representing a high sport level, who is a participant in the European and World Championships and the Olympic Games. The video recordings were made under simulated starting conditions of a 110 m hurdle race. Kinematic parameters are estimated based on the analysis of images from a multicamera system. The images were recorded with a resolution of 1920x1080 and with a frequency of 100 Hz. The proposed method does not use any special clothes, markers or other estimation support techniques. The parameters of the hurdle clearance were compared with the parameters obtained from ground truth poses. Mean Absolute Error and Mean Relative Error were used as the quality criteria.

Authors:

Hiromu Otani, Fumito Masui, Hitoshi Yanagi and Michal Ptaszynski

Abstract: Japanese curling teams have been recently preparing for Pyeongchang Winter Olympics in 2018. In curling, there are three factors influencing game performance: physical factor, human factor, and strategic/tactical factor. The strategic/tactical factor is considered as the most important at top level. To support the strategic/tactical factor, we proposed the concept of Curling Informatics. As the first step of Curling Informatics we developed a digital scorebook iCE for digital collection of game information, storing it in a database and performing further analysis to improve player performance. In this article, we further contribute to this project by analyzing game information of world national top level teams. We have previously confirmed that correlation between shot accuracy and game score could differ with the team level or position. We also found out that selected tactics and psychological pressure on opponent team has impact on game result. However, previous analyses disregarded the order of teams in play, which could result in confusion of strategic tendencies or play characteristics. In this paper, we carried out analysis of correlations of shot scores considering whether the teams started as the first or the second. We did this to specify the process of how the team strategy/tactics influences game results.

Running Race Times Prediction and Runner Performances Comparison using a Matrix Factorization Approach

Authors:

Dimitri de Smet, Michel Verleysen and Marc Francaux

Abstract: This work provides tools based on matrix factorization that can be used to predict athlete running race times based on known race results. This is of interest for athlete preparation, for workout route planning and for race events organization. This work differentiates from previous ones by jointly considering athletes and routes. This work shows how race records can be used to infer knowledge on the users and the races. The same tools can also serve to compare different athlete performances and track athlete level over time. Experiments were conducted on race records of 648 athletes from casual to elite levels. Experiments show that the methodology can be applied to real data and gives relevant insights.

Kinematic Analysis of the Upper Limbs in Stepping over the Hurdle - The Use of IMU-based Motion Capture

Authors:

Janusz Iskra, Krzysztof Przednowek, Tomasz Krzeszowski, Krzysztof Wiktorowicz and Michal Pietrzak

Abstract: This paper presents an analysis of the kinematic parameters of the upper limbs in stepping over the hurdle. Stepping over the hurdle is a specific exercise practised throughout the year. In this exercise, three key points were analysed in take-off, flight and landing phases. The aim of the study was to use the IMU-based (inertial measurement unit) motion capture system to evaluate the movement of the hurdlers’ upper limbs while stepping over the hurdle using both the better leg, and the worse leg. The sequences were obtained using 18 sensors working at a frequency of 120 Hz. The analysis was made using two high-achieving athletes. This paper presents the linear velocities and the trajectory of selected segments of the upper limbs. In most cases the velocities of the segments were higher for the better leg. The analysis shows that during the specific exercise of stepping over the hurdle attention should be paid to the movement of the trail arm in the landing phase.

Preparations before experiment: before the experiment, some medical examinations are necessary to conduct so as to exclude the exercise taboos of the people tested and understand their living habits, diet conditions, medication and exercise habits.2. Implementation of intervention program:Combined intervention, DASH dietary patterns and 5-7 times one-hour exercise (with five options of brisk walking, dancing, running, gymnastics and cycling) with moderate intensity, for 6 months are conducted.Principles of DASH diet: plenty of fruits, vegetables and low-fat dairy products; reducing the intake of food that are rich in saturated fat, cholesterol and trans fat; appropriate amount of whole grains, poultry, fish and nuts; control the intake of sodium, dessert, sugary drinks and red meat. As for DASH diet, reduction of sodium plays a key role. In addition to standard DASH diet (daily intake of 2300mg), a low sodium version (daily intake of 1500mg) is available for different health needs.3. Test indexes: (1) Index for the survey of basic conditions: personal basic information, disease, daily physical activity, drugs, and diet. (2) Blood pressure monitoring. It should be completed by the same tester and the cuff should be fixed on the right upper arm of the patient. During the automatic test, the upper arm should remain relatively steady to ensure the validity of the data obtained; the test time is 8:00-10:00 am. (3) Blood biochemical indexes. All subjects should fast for more than 12 hours, and 5ml venous blood sample should be taken the next morning for the test of total cholesterol (TC), triglyceride (TG), fasting blood-glucose and other indicators.4. Test instruments: (1) Glucometer produced by Roche Group is used in fingertip blood glucose of FBG; (2) the enzyme method is used in TC and TG.(III) Statistical MethodsThe SPSS 10.0 statistical software is used to analyze the one-way variance. The comparison between groups and the paired t test before and after the intervention are conducted for statistical analysis. The difference was statistically significant with p<0.05.III. Findings(I) Comparison of blood pressure (mmHg) before and after interventionAfter the intervention, the systolic blood pressure decreases. There are significant differences between the two groups before and after intervention with p<0.001; diastolic blood pressure decreases after intervention, and the difference was significant before and after the intervention, with p<0.0001, which is available in table 1.Table 1 Systolic and diastolic blood pressure levels (x + s) after interventionSystolic blood pressure Diastolic blood pressureBefore intervention After intervention t p Before intervention After intervention t p155.42±17.71 129.24±6.19 21.25 <0.0001 93.48±11.56 80.89±6.20 12.01 <0.001(II) Control of blood pressure after interventionThe rate of blood pressure control after intervention is 84%; which is available in table 2.

After intervention, blood sugar decreases by 0.48 + 0.90 mmol/L, and blood sugar in intervention group decreases obviously, which is available in table 3.Table 3 Blood glucose level (x + s) after the interventionBefore intervention After intervention D-value t p5.63± 1.20 5.15± 0.504 -0.48±0.90 6.23 <0.001(IV) Comparison of cholesterol (mmol/L) levels before and after interventionAfter intervention, the serum cholesterol level decreases obviously, and the difference is significant (17.55, P<0.001), which is available in table 4.Table 4 Cholesterol level after intervention (x + s)Before intervention After intervention D-value t p5.10± 1.10 4.13± 0.24 -0.97± 1.01 17.55 <0.001(V) Comparison of triglyceride (mmol/L) levels before and after interventionAfter the intervention, the serum triglyceride level decreases obviously, and the difference is significant (t=11.62, P<0.001), which is available in table 5.Table 5 Triglyceride level (x + s) after the interventionBefore intervention After intervention D-value t p2.13± 0.97 1.60± 0.43 -0.53± 0.64 11.62 <0.001IV. Analysis and discussionAfter 6 months of combined intervention, the average systolic pressure of the subjects decrease by 26.28mmHg, and the average diastolic pressure decrease by 12.59mmHg. In China, seniors with isolated systolic hypertension account for 53.21% of the total population who suffered from hypertension. The increase of systolic blood pressure and pulse pressure to a certain extent reflects the disease of arterial sclerosis, and it has been proved through study as the independent risk factor of various cardiovascular and cerebrovascular diseases. Therefore, after the combined intervention, the systolic blood pressure drops in elderly hypertensive patients is greater than that of diastolic blood pressure, which is extremely beneficial to preventing cardiovascular and cerebrovascular diseases of the elderly people that is caused by the increase of systolic blood pressure.According to the results of randomized controlled trails in the west, if the systolic pressure decreases by 10-14mmHg or diastolic blood pressure decreases by 5-6mmHg, the risks of suffering from strokes and coronary heart disease can be reduced by 2/5 and 1/6 respectively. Moreover, the occurrence of cardiovascular disease in the same group can be reduced by 1/3. If the decrease of systolic blood pressure by 10mmHg and/or the decrease of diastolic pressure by 5mmHg are treated as an effective criterion in blood pressure reduction, falling range of most subjects’ blood pressure can be seen as effective value.Effect of comprehensive intervention on blood lipids in elderly patients with hypertension. Related studies show that the increase of serum total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C) is one of the independent risk factor for coronary heart disease and ischemic stroke. From 3.63mmol/L, the risk of ischemic cardiovascular disease increases with the increase of TC level. As LDL-C and TC are in parallel, the risk tendency and degree of ischemic cardiovascular disease is similar as that of TC with the increase of LDL-C. In this study, average TC levels of the elderly patients with hypertension before and after the intervention are 5.1mmol/L and 4.13mmol/L respectively. TC level after the intervention is still higher than 3.36mmol/L, which suggests that the risk of ischemic cardiovascular disease in elderly hypertensive patients is still high.The main content of diet and exercise intervention is to reduce saturated fat and cholesterol intake, and to achieve energy balance by controlling the total calories and increasing physical activity. At the same time, salt intake should be reduced so as to prevent hypertension. The goal of dietetic treatment is to ensure that the subjects have a healthy diet and balanced nutrition by taking into account the specific factors of gender, age and labor intensity.V. Conclusion(I) Reducing the intake of cooking oil, salt and livestock, and increasing the intake of vegetables, fruits and low-fat dairy products are necessary and effective measures for the prevention and treatment of hypertension.(II) Through balanced dietary intervention and exercise, systolic blood pressure under comprehensive intervention decreases significantly.

Pedobarographic Profile of Gait in Patients with Ankylosing Spondylitis

Authors:

Igor Gruić, Frane Grubišić, Simeon Grazio and Vladimir Medved

Abstract: Ankylosing spondylitis (AS) is chronic inflammatory rheumatic disease which predominantly affects sacroiliac joints and spine and, during course of time, may also alter posture, movement patterns and regulation and quality of life. Clinical diagnostic tools for assessment of AS internalizations complement different qualitative and quantitative methods. Externalisations of axial skeleton alterations, followed by hip, knee, ankle and foot joints posture and movement adjustments, are quantified by conservative biomechanical approach. Items representing functional status and disease activity in AS patients correlated to pedobarographic status were anchored to previous research, i.e. Doward et al., 2003; Grazio et al., 2009; Aydina et al., 2015; Giacomozzi, 2010; Gruic et al., 2015; Gruic et al., 2016. Contrary to previous findings, multiple correlation between clinical scores and dynamic pedobarographic measurements was established.

Authors:

Coline Jamme, Kaveena Devi Persand, Georges Soto-Romero and Annabelle Vigué

Abstract: Many older people give up all physical activities because of their feeling of insecurity outdoors. In parallel, the number of Electrically Assisted Cycles (EAC) in the cities increases significantly. Purpose: The aim of the current study is to know if it’s possible to monitor their heart rate via an EAC to give a secure access to locomotion of people under medical advice. Methods: It is two-fold: For all the experiments, our reference is the Polar H7 chest strap. First, we compared different sensor’s positions during a 30 seconds’ effort test indoors on a healthy subject. Then, we studied the repeatability and the reproducibility of the PulseSensor placed on the cyclist’s earlobe during rest and test efforts on two samples of 12 health subjects. Results: The PulseSensor placed on the earlobe is reliable indoors. Conclusion: The PulseSensor can be a good sensor to monitor an EAC in heart rate. But we need to design a system to integrate all the electronic directly on the cyclist and his helmet and to protect it from the outdoors interactions like the exposure to the sun, the humidity or the cyclist’s perspiration.

Title:

A Pilot Study to Examine the Activity of Primary Plantar Flexor Muscles using an Electric Motorized Treadmill in Comparison to Overground Walking

Authors:

Katja Orlowski, Dennis Wagner, Annett l'Orteye, Heike Ringk, Verena Kohl and Thomas Schrader

Abstract: The gait during overground (OG) and treadmill (TM) walking was already investigated by different scientific groups. Differences in the muscle activation and in the kinetics were found. The aim of the present examination was to find conditions for a comparable or higher activation of the plantar flexor muscles during TM walking in order to give recommendations for training and rehabilitation. A pilot study with different conditions (e.g. with and without inclination) was done. Furthermore, the aspect of different walking velocities in OG and TM walking was investigated. The self selected speed was reduced during TM walking (1.1 km/h). Regarding the muscle activation, it is recognizable that the primary plantar flexor muscles react similarly. The activation is reduced during TM walking. Based on the inclination of 1.5 %, a little larger activity during TM walking is observed for the muscles M. gastrocnemius medialis and lateralis. Our results confirm that there are differences between OG and TM walking in the activation of the primary plantar flexor muscles. The results indicate that there is an effect of different, adjustable conditions (speed and inclination). Further examinations are planned to find detailed information about the different conditions and their impact on the muscle activation.

Influence of Selection of Release Angle and Speed on Success Rates of Jump Shots in Basketball

Authors:

Yuki Inaba, Noriko Hakamada and Munenori Murata

Abstract: Enhancing the successful jump-shot percentages in basketball is critical for winning a game. A selection of release parameters and variability can influence the success rate, but the actual selection of the release parameters and variabilities in those during jump shots and the influence of this selection on success rate have not been investigated and are not understood well. Thus, the purpose of this study was to investigate the influences of the selection of release angle, release speed and spin rate, and variability on the success rate of jump-shots in basketball. Ten male collegiate basketball players participated in the study and actual ball trajectories for the jump-shots from the free-throw (FT) and three-point (3P) lines were recorded by the three-dimensional motion analysis system. The experimental data was compared with the theoretical optimal release parameters. We found that the players with higher success rate in FT shots had a higher release position, a lower release velocity, and a larger margin for error for the release speed. On the other hand, for the 3P shots, the player with a larger margin for error for the combination of the release speed and angle had higher success rate. Variability in release parameters did not have significant correlation with the success rate. Thus, it can be said that selecting the release parameters that allow greater margin for error was important for increasing the success rate. Also, depending on the required release speed or the shooting distance, the strategies for the selection of the release parameters must be adjusted to increase the success rate in jump-shots.

Authors:

Anna Zakharova, Kamiliia Mekhdieva and Anastasia Berdnikova

Abstract: Young athletes require a specialized approach to training process, taking into consideration a broad range of physiological and training aspects. The study is focused on the evaluation of fitness level of young soccer players and the search for interrelations between parameters of laboratory and field tests with the physiologic measurements during match play. The proposed paper provides coaches, sports scientists and physicians with important information on effective training control based on accessible and reliable tests. Twenty six healthy male soccer players born in 2004 currently aged 12-13 were recruited for the study. Data obtained from laboratory testing (cycling stress-test with gas-exchange measurements, Wingate cycling test, and blood lactate measurements), maximal interval running field test and soccer game analysis with heart rate monitoring were analysed. Firstly, Wingate cycle test parameters in young soccer players aged 12-13 were described in details. Furthermore, significant interrelations between indicators of physical state, obtained from the various types of tests were revealed. The most important finding was close correlations between measured indicators during the game with results of laboratory and field tests. Based on mentioned above, laboratory and field tests can be widely used in training control of young soccer players.

Authors:

Eng Hoe Wee, Jiun Yang Low, Kai Quin Chan and Hui Yin Ler

Abstract: Despite the fact that High Intensity Intermittent Training (HIIT) resulted in physiological adaptations and started to be applied on racket sport, the effectiveness of HIIT in a multi-shuttle feeding form to improve physical performance in badminton has not been extensively examined. This study investigated the effects of high intensity intermittent badminton multi-shuttle feeding training on aerobic and anaerobic capacity, reactive leg strength and agility. Eighteen university college badminton players aged 20±1 participated in this study. Based on the initial test results on aerobic and anaerobic capacity, leg reactive strength, and agility parameters, subjects were randomly divided into 2 groups (control group [CG], experimental group [EG]). The results showed that there were significant improvements in VO2max, mean power, reactive strength and agility but not peak power and jump height in EG. CG showed no improvement in all parameters.

Authors:

Anna Zakharova, Kamiliia Mekhdieva and Svetlana Kondratovitch

Abstract: Basketball is a very demanding sport. Game effectiveness depends on a large number of physical and psychological abilities, technical competence, etc. Thus appropriate comprehensive complex approach to laboratory testing and its data interpretation play a considerable role in suggestion the proper training prescription and schedule, taking into consideration weak points of tested athletes. The aim of the proposed study was to choose appropriate and accessible laboratory testing methods and present their results. Fourteen professional male basketball players aged 24.8±5.4 years underwent bioimpedance analysis of body composition, maximal cycling test, hemodynamics monitoring, Wingate-test, jump performance analysis and psychophysiologic tests. These allowed to define the physical and psychophysiologic profiles of athletes. It was revealed, that (i) athletes had low percentage of fat (10.3±4.7 %) and high level of muscle mass (85.4±4.5 %); (ii) excellent volume heart parameters (SV – 137.00±19.93 ml) and low RHR – 49.08±6.56 bpm; iii) lowered VO2max 47.52±6.14 ml/kg/min, Ve – 145.3±36.4 l/min, P VO2max – 4.13±0.58 W/kg; (iiii) lower than expected strength abilities – peak power of arms – 6,47 ±0,87 W/kg and relative maximal power of legs – 42,17±4,22 W/kg, respectively. The obtained data provided with valuable information for further improvement of training process.
