| 6 | Enhancements to Modified Chebyshev-Picard Iteration Efficiency for Perturbed Orbit Propagation显示文摘Modified Chebyshev Picard Iteration is an iterative numerical method for solving linear or non-linear ordinary differential equations.In a serial computational environment the method has been shown to compete with,or outperform,current state of practice numerical integrators.This paper presents several improvements to the basic method,designed to further increase the computational efficiency of solving the equations of perturbed orbit propagation. | B.Macomber A.B.Probe R.Woollands J.Read J.L.Junkins | 2016 | Computer Modeling in Engineering & Sciences2016，，1： | 0 |
| 7 | The Effects of a Four-Week Neuromuscular Training Program on Landing Kinematics in Pre-and Post-Peak Height Velocity Male Athletes显示文摘Purpose Neuromuscular training aims to enhance motor skill competency and increase muscle strength.However,the effectiveness of short-duration interventions focused on addressing lower limb injury risk factors in male youth athletes at different stages of maturity remains unknown.Methods Forty-eight young male academy cricket players[pre-peak height velocity(PHV)(n=26)and post-PHV(n=22)]were subdivided into an experimental group(EXP)who completed a 4-week progressive neuromuscular training program and controls(CON)participating in sport training only.Changes in injury risk were examined using the Tuck Jump Assess-ment(TJA)and Landing Error Scoring System(LESS).Results Total LESS score was significantly lower in both EXP maturity groups compared to CON following the 4-week program(10 to 6 and 6 to 4(~20%to 40%))in the pre-and post-PHV EXP groups,respectively.Significant within-group reductions in total LESS score were shown for the pre-PHV EXP group only(P<0.05).Conversely,greater changes in TJA total score were shown in post-PHV(5 to 3;40%)versus pre-PHV EXP(6 to 4.5;26%).Pre-PHV players showed positive changes in individual LESS criteria indicative of frontal plane control but not in knee valgus during the TJA,whereas post-PHV players did improve this criterion.Conclusion This study indicates it is possible to reduce TJA and LESS scores in male youth athletes by performing a 4-week neuromuscular training program,improving landing mechanics and reducing injury risk irrespective of maturity,but their effects are somewhat influenced by stage of maturation and the task performed. | Paul J.Read Jon L.Oliver Ian J.Dobbs Megan A.Wong Nakul Tumkur Anil Kumar Rhodri S.Lloyd | 2021 | Journal of Science in Sport and Exercise2021，3，1： | 0 |
| 8 | Utility of Kinetic and Kinematic Jumping and Landing Variables as Predictors of Injury Risk: A Systematic Review显示文摘Purpose Jump-landing assessments provide a means to quantify an individual’s ability to attenuate ground reaction forces,generate lower limb explosive power and maintain joint alignment.In order to identify risk factors that can be targeted through appropriate training interventions,it is necessary to establish which(scalar)objective kinetic,kinematic,and performance measures are most associated with lower-extremity injury.Methods Online searches of MEDLINE,SCOPUS,EBSCOHost,SPORTDiscus and PubMed databases were completed for all articles published before March 2020 in accordance with PRISMA guidelines.Results 40 articles investigating nine jump-landing assessments were included in this review.The 79%of studies using drop jump(n=14)observed an association with future injury,while only 8%of countermovement jump studies(n=13)observed an association with injury risk.The 57%of studies using unilateral assessments found associations with risk of injury(n=14).Studies using performance measures(jump height/distance)as outcome measure were only associated with injury risk in 30%of cases.However,those using kinetic and/or kinematic analyses(knee abduction moment,knee valgus angle,knee separation distance,peak ground reaction force)found associations with injury in 89%of studies.Conclusion The landing element of jump-landing assessments appears to be superior for identifying individuals at greater risk of injury;likely due to a closer representation of the injury mechanism.Consequently,jump-landing assessments that involve attenuation of impact forces such as the drop jump appear most suited for this purpose but should involve assessment of frontal plane knee motion and ground reaction forces. | Jason S.Pedley Rhodri S.Lloyd Paul J.Read Isabel S.Moore Mark De Ste Croix Gregory D.Myer Jon L.Oliver | 2020 | Journal of Science in Sport and Exercise2020，2，4： | 0 |
| 9 | The Influence of Biological Maturity on Dynamic Force-Time Variables and Vaulting Performance in Young Female Gymnasts显示文摘Purpose This cross-sectional study investigated dynamic force-time variables and vaulting performance in young female gymnasts of different maturity status.Methods 120 gymnasts aged 5-14 years were sub-divided into maturity groupings using percent of predicted adult height(%PAH)attained.Participants performed three jumping protocols,the squat jump(SJ),countermovement jump(CMJ)and drop jump(DJ),before completing straight jump vaults that were recorded using two-dimensional video.Results Jumping performance improved with biological maturity evidenced by the most mature gymnasts’producing sig-nificantly more absolute force(P<0.05;all d>0.78),impulse(P<0.05;all d>0.75)and power(P<0.05;all d>0.91)than the least mature group,resulting in the greater jump heights(P<0.05;all d>0.70).While,no significant differences were observed in relative peak force across multiple tests,measures of relative peak power did significantly increase with maturity.Based upon regression analyses,maturation was found to influence vertical take-off velocity during vaulting,explaining 41%of the variance in each jumping protocol.Across all tests,the DJ was found to have the highest predictive ability of vaulting vertical take-off velocity,explaining 55%of the total variance.Conclusion Biological maturation impacts jump height and underpinning mechanical variables in young female gymnasts.Vaulting vertical take-off velocity appears to be influenced by maturation and various dynamic force-time variables,par-ticularly those during DJ,which had the highest explained total variance. | Sylvia Moeskops Jon L.Oliver Paul J.Read John B.Cronin Gregory D.Myer G.Gregory Haff Isabel S.Moore Rhodri S.Lloyd | 2020 | Journal of Science in Sport and Exercise2020，2，4： | 0 |
