THE IMPACT OF BRIEF ELECTRONIC GUIDED MINDFULNESS MEDITATION ON ANXIETY SCORES
Get PDFIn the United States, anxiety rates are on the rise for the general population (Goodwin et al., 2020a). Prolonged and frequent anxiety can become unprompted and problematic (American Psychiatric Association, 2021). Management of anxiety is crucial for overall wellbeing. Access to treatment and resources for anxiety may be limited in rural geographical locations (Morales et al., n.d.). This DNP project sought to determine whether a brief intervention of electronic guided mindfulness meditation (MM) by Insight Timer is effective in decreasing anxiety in a rural populous. Convenience sampling recruited a final total of 11 rural participants who participated in seven sessions of mindfulness meditation over a 14-day period. Analysis via permutation testing of Zung Self-Rating Anxiety Scale scores from pre/post scores showed the intervention of MM to be statistically significant (p=0.0015)
A KINEMATIC ANALYSIS OF SHOT PUTTERS AT A DIVISION I UNIVERSITY
Get PDFThe purpose of this research was to examine the peak height during the flight phase and trunk kinematics during the landing phase, and their effects on throwing distance in the shot put using MOCAP. A secondary purpose was to examine differences between the throwing styles and gender. The participants were 12 university-level shot put throwers (six males, six females). A technique by trunk angle interaction effect just below the level of significance was found (p = .056). Significant relationships were found between throw distance and trunk lateral flexion, with females throwing further with more flexion toward their throwing arm (p = .022). The findings may help coaches understand kinematic positions exhibited by shot putters, the relationship to throwing distance, and differences between throwing styles and sex
COMPARISONS OF HEAD IMPACTS BETWEEN KOREAN YOUTH ATHLETES AND NON-ATHLETES IN SOCCER HEADINGS
Get PDFThe purpose of this study was to quantify the intensity and location of head impacts and compare them between high school soccer athletes and non-athletes. Twenty participants performed five goal-kick and five corner-kick soccer ball headings projected by a ball launcher machine. The head injury criterion (HIC) was calculated from the linear acceleration data from a head-attached inertial measurement unit (IMU) sensor. Results indicated there was no significant difference in HIC between the two groups. The HIC for forehead impacts was significantly lower than those for parietal contact. Coaches need to guide students to perform the forehead header in order to reduce the risk of accumulated head damage
EXAMINING THE IMPACT OF APPROACH AND EXIT PHASE STRATEGIES ON CHANGE OF DIRECTION PERFORMANCE: A NOVEL METHODOLOGY
Get PDFThis study used new insole pressure technology to examine how movement strategies during approach and exit phases affect change of direction (COD) times. Participants (n=26) wore NURVV smart insoles and performed 90˚ cuts off each leg (dominant [Dom] and non-dominant [ND]). Ground contact time (GCT), cadence, centre of pressure, and return to linear sprinting metrics were analysed for four steps about the cut-step. Faster cadence and a more forefoot strike pattern predicted 58% of the variance in Dom side COD ability. ND COD ability was predicted by a faster cadence immediately post-cut and a quicker GCT two steps before the cut-step (66% of variance explained). These findings emphasize the approach phase’s crucial role in COD ability and stress the need to examine multiple steps around the cut-step for a complete understanding of COD mechanisms
INFLUENCE OF ADVANCED FOOTWEAR TECHNOLOGY ON PERFORMANCE AND BIOMECHANICS DURING MOUNTAIN RUNNING
Get PDFThe purpose of this study was to evaluate the effect of the advanced footwear technology (AFT) on performance and biomechanics during mountain running. Twelve male mountain-runners performed two running time-trials over a 5.19 km mountain circuit (1.68 km uphill, 1.56 km downhill and 1.95 km mixed) using conventional (CON) and carbon fibre plate shoes (CFP) in a randomized order (i.e., CON-CPF and CFP-CON). Total time, heart rate, RPE and biomechanical variables were registered. The AFT did not affect performance, heart rate, RPE and running power, but increased contact time and step length, decreasing step frequency in the order CON-CFP, mainly during the uphill and downhill segments. In conclusion, the AFT did not affect performance during mountain running, but the observed changes in the running biomechanics should be widely explored
COURT LOCATION DOES NOT AFFECT FEMALE COLLEGIATE BASKETBALL PLAYERS’ SHOOTING MOVEMENT PATTERN
Get PDFThe core basketball shooting movement pattern includes a coordinated sequence of a countermovement followed by shoulder flexion then elbow extension, parameterized by distance to the basket. We assessed how this core shooting movement pattern varied among different court locations. Two cameras recorded videos of a collegiate women’s basketball team (n = 11) shooting from four court locations. 3-D whole-body kinematics were measured by identifying joint centres in the videos, direct linear transformation of 2-D video coordinates, and Euler angle calculations. A principal component analysis was run and identified four relative timing components of the core basketball shooting movement pattern, which did not vary with court location (λ1 = 3.94, λ2 = 3.33, λ3 = 1.55, λ4 = 1.00). Basketball shooting technique is more complex than commonly coached, but robust
TRUNK RESISTANCE DURING SINGLE LEG JUMPS IMPROVES TRUNK MOVEMENT IN COLLEGE ATHLETES WITH POOR MOVEMENT QUALITY
Get PDFExcessive trunk movements during sports gestures are commonly observed in lower limb injuries. Considering that poor movement quality and strength deficits in trunk and hip muscles have been associated with this excessive trunk movement, training of trunk control is needed in athletes. This study described the acute effects of an external trunk resistance in the sagittal and transverse planes during single-leg jumps in trunk kinematics of 20 female college athletes with poor movement quality of the lower limbs. The peak angles and range of motion of the trunk with and without resistance was compared. A decrease in the minimum peak flexion, a reduction in the range of movement in frontal plane and, an increase in the range of movement in the transverse plane were observed with trunk resistance
KINEMATIC SEQUENCING OF THE SHORT GAME SWING IN MALE COLLEGIATE GOLFERS
Get PDFApproach shots are crucial to the success of elite golfers. The primary purpose of this study was to compare kinematics of golf shots at four target distances (30, 50, and 70 yards, and full swing) in collegiate, male golfers. Participants were instructed to hit five successful shots at each target distance. A motion capture system recorded kinematic and temporal parameters of the golfers and a golf simulator collected ball carry distance of each shot. Distance had a significant (p ≤ 0.05) effect on swing phase timing, angular velocities, and motion sequencing. Movement sequencing within the short game displayed irregular patterns across all distances and phases. The findings of this study show that the short game swing did present its own unique motion patterns that will require practice as its own skill
Förster Resonance Energy Transfer-Based Quantification of D-2-Hydroxyglutarate & Locked Nucleic Acid Loop-Mediated Isothermal Amplification Mediated Detection of IDH1-R132 Single Nucleotide Variants in Glioma
No full textIsocitrate dehydrogenase 1 (IDH1) is a biomarker in gliomas which provides valuable information on patient prognosis and treatment. Targeted therapies including maximal surgical resection and pharmaceutical mutant IDH inhibitors offer life extending benefits; however, currently implemented assays for the detection of IDH1 mutations do not function in a timely manner and cannot offer convenient monitoring of mutational status during treatment. Here, we describe the development and characterization of a novel dual diagnostic system consisting of a fluorescent biosensor and genotyping panel, which may collectively allow for the preoperative, intraoperative, and/or postoperative elucidation of IDH1 mutational status. The fluorescent biosensor quantifies D-2-Hydroxyglutarate (D-2-HG), an oncometabolite and surrogate marker of IDH1 mutations, while the genotyping panel identifies the specific IDH1-R132 single nucleotide variant (SNV) present. The biosensor’s robust function in biological fluids suggests its powerful utility in liquid biopsies and monitoring remission vs. recurrence, while the genotyping panel aids in the genetic detection of oncogenic missense mutations. In our hands, both assays have demonstrated 100% accuracy in discriminating between IDH1 wildtype and IDH1 mutant glioma tumors, offering exciting preliminary findings that support the implementation of these rapid diagnostic tools. In addition, the fluorescent biosensor detects depletion of D-2-HG resulting from mutant IDH inhibitors, suggesting its value in the future development of novel pharmaceutical treatments targeting mutant IDH
