Impact of Deadlift and Power Clean on Vertical and Broad Jump Performance

A transfer between weightlifting and jumps is based on principles of increased demands being placed upon the muscular system while performing similar movement patterns. The purpose of the study was to investigate the impact of power-clean (PC) and deadlift (DL) interventions on vertical-jump (VJ) and broad-jump (BJ) performance in college-aged males. The hypothesis stated PC intervention would show greater improvements in BJ and VJ than DL intervention. The null hypothesis stated no difference between DL and PC groups would be found in affecting VJ and BJ performance. Six males who were not D-I athletes and were experienced with required movements were recruited for the study. Participants were randomly assigned to DL intervention, PC intervention, or control group. ORPYX shoe pods were placed in participants shoes to measure force produced in jumps and lifts. All participants performed pre-intervention max VJ and BJ testing. Jump testing was followed by max PC and DL testing for respected groups. Participants in DL and PC interventions performed a training protocol three days a week for six-weeks. Post-intervention, subjects were re-evaluated in jumps and lifts. Data was analyzed through ORPYX and transferred to Excel for further analysis. Means and standard deviations for force, jumps, and lifts were calculated and analyzed through SPSS. A one-way ANOVA was used to analyze data. Improvements occurred, but no statistically significant difference was observed (p \u3c .05). The null hypothesis was accepted; no significant differences were found between DL and PC in affecting VJ and BJ performance

Instantons on Calabi-Yau cones

The Hermitian Yang-Mills equations on certain vector bundles over Calabi-Yau cones can be reduced to a set of matrix equations; in fact, these are Nahm-type equations. The latter can be analysed further by generalising arguments of Donaldson and Kronheimer used in the study of the original Nahm equations. Starting from certain equivariant connections, we show that the full set of instanton equations reduce, with a unique gauge transformation, to the holomorphicity condition alone.Comment: v2: 26 pages, accepted in Nucl.Phys.B, added 6 references, improved discussion, added Yang-Mills with torsio

Coulomb branches for rank 2 gauge groups in 3d N=4 gauge theories

The Coulomb branch of 3-dimensional N=4 gauge theories is the space of bare and dressed BPS monopole operators. We utilise the conformal dimension to define a fan which, upon intersection with the weight lattice of a GNO-dual group, gives rise to a collection of semi-groups. It turns out that the unique Hilbert bases of these semi-groups are a sufficient, finite set of monopole operators which generate the entire chiral ring. Moreover, the knowledge of the properties of the minimal generators is enough to compute the Hilbert series explicitly. The techniques of this paper allow an efficient evaluation of the Hilbert series for general rank gauge groups. As an application, we provide various examples for all rank two gauge groups to demonstrate the novel interpretation.Comment: v2: 98 pages, 30 figures, 34 tables, 1 appendix, matches JHEP versio
