CHARACTERISTICS OF STRENGTH AND POWER FOR THE RATE OF FORCE DEVELOPMENT DURING LEG EXTENSION
A multi-strength tester (MST) was developed to assess the rate of force development (RFD) during isometric leg extensions. This study aimed to examine the relationship between RFD measured by MST and strength and power performance. Participants performed isometric leg presses with MST, countermovement jumps, squat jumps (SJ), and concentric squat of 70% of 1 repetition maximum (sq70). Significant correlations were found between the early phases of RFD measured by MST and countermovement jump. There were no significant correlations found in SJ. The late phase of RFD measured by MST significantly correlated with sq70. The present results suggest that the early phases of RFD with MST relate with countermovement during jump performance. The late phase of RFD with MST relate with the ability of generating force under heavy resistance
KINEMATIC ANALYSIS OF SOCCER INSIDE KICK MOTION FOR STATIONARY BALL AND PROJECTED BALL
The purpose of this study was to analyse the inside kick motion kinematically under the mimic situation of a soccer game, by comparing the motion of kicking the stationary ball on the ground with the motion of kicking the ball projected from the launcher machine. Five male university soccer players conducted inside kicks under the two conditions of the stationary ball and the projected ball. The kicking motion were collected with an optical motion capture system. From the results of this study, the following were suggested as a motion to kick a projected ball. 1) Adjustment of hip joint adduction-abduction and knee flexion-extension were important so as to correspond the swing trajectory to the ball. 2) It is important to kick an upper part of ball
EXTERNAL MOMENT AROUND THE CENTRE OF MASS DURING GOLF SWING IN DIFFERENT WEIGHT TRANSFER STRATEGIES
The purpose of this study was to investigate the external moment around the centre of mass (COM) during the golf swing in golfers using different weight transfer strategies. The swing motions of twenty-one male golfers were captured by three-dimensional motion capture system. Ground reaction force of each foot was measured. External moments were calculated as the cross-product of the position vector from the COM to centre of pressure and ground reaction force vector. The golfers were divided into two groups whether the centre of pressure positioned front (n=8) or rear (n=13) relative to the COM at the impact. The external moments around the COM were not significantly different between two groups at the impact. It means that the golfers in different weight transfer strategies generate equivalents external moment by different strategies
PREDICTORS OF BOULDER CLIMBING PERFORMANCE IN YOUTH BOULDER CLIMBERS
The purpose of this study was to determine if a simple measurement using hand dynamometer could be used as predictors of boulder climbing performance in youth climbers. The study cohort consisted of 12 competitive climbers (8 males, 4 females) who competed at European Bouldering Youth Championships (B) in Slany, Czech Republic in the year 2017. The hand grip force was measured at fingertips-thumbtip grip at three wrist positions and during free holding. The effect of hand dominance in grip strength was not observed except for free holding. It could be concluded that the elite young climbers has balanced grip strength between the left and the right hand. The performance in competitions was assed by total number of number of achieved tops. The best predictor of number of top holds achieved in qualification round was the strength at free grip as it describes also upper body fitness level
SCIENCE TO COMMERCIALISATION –TRANSLATING SCIENCE TO COMMERCIAL OUTCOMES
Validation is a critical component to the scientific method and translation of scientific knowledge, algorithms, and technology to real-world sporting or clinical settings, and requires rigorous testing by multiple stakeholders. This process can take decades to have an influence on clinical practice. Validation is also a crucial part of translating technology and science into commercial application, although in this context validation needs to take into account usability, manufacturing, price/performance trade-offs, finding a product-market fit and determining your value proposition in the market place. This discussion will draw on the experience of a diverse panel to highlight some of the challenges of translating science to commercial applications. By illustrating through examples from the diverse and experienced panel members, various validation methods and their implications for commercialising a product or algorithm, compared with validating a hypothesis, will be covered

wait for it to bloom.
wait for it to bloom. is a poetry collection of free verse poetry that examines black motherhood and womanhood in order to interrogate the sociopolitical implications of black women’s existence in a patriarchal, capitalistic society. Due to the intersections of our identities, black women face a specific type of discrimination that spans both racism and sexism, among other types of discrimination. The healing properties associated with astronomy and mythology are used as entry points to discuss this trauma, while popular culture is used to address these issues that happen daily in the media directly. This consistent bombardment of prejudice, along with our global society’s inability to acknowledge and properly treat mental illnesses, can cause problems with mental health; black women’s ostracization from each of these communities causes an erasure that spans generations, leading many to suffer in silence. Through intentionality in structure with white space, punctuation, and forward slashes, this collection attempts to remedy the plight of the black women while engaging in a journey of healing and power through language
The Wrong Side of Yesterday
These chapters start off a novel that follows Simon Jones, a man brought back to the city of Decatur, Illinois by the death of his sister. Simon is left taking care of Jeffrey, a ten-year-old boy with an arm that loses skin constantly and glows a dull white. While Simon and Jeffrey navigate their grief and uncertain futures, the city is rocked by a series of murders that target “divergents,” people with physical abnormalities like Jeffrey’s arm. The Wrong Side of Yesterday is a novel that uses elements of magical realism and mystery to explore issues of grief, disability, poverty, and identity, all within the confines of a dying Midwestern city
PERFORMANCE CHARACTERISTICS OF ADULT ONE DOG CANICROSS RUNNERS
Canicross is competitive team sport in which a human athlete is towed via a canine athlete on an elastic gangline. Although drastically understudied, it is likely that canicross performance comes down to differences in human aspects, canine aspects and the interaction between human and canine. The purpose of this study is to identify and assess the influences of several performance factors on a time trial canicross event. Survey data was taken upon arrival at the event. During the event, video was taken at five locations along the trail of two different competitive canicross events. Correlation analysis was used to identify relationships between all independent variables taken from survey and video data. Further, a multiple linear regression analysis was used to predict time-trial performance and a one-way repeated measures ANOVA was used to determine differences in synchronization scores across locations. The results of this study found significant correlations between performance and the time spent in training without the dog, as well as, normal dog position. Regression analysis revealed that performance can be predicted via percentage of time spent in overall canine front left foot flight and overall human mid-stance, in relation to overall stride. Lastly, synchronization scores did not differ significantly across locations. Future research should continue to investigate optimal synchronization patterns in high-level canicross athletes
