OBJECTIVE The purpose was to examine differences between taekwondo kicks and boxing punches in resultant linear head acceleration (RLA), head injury criterion (HIC15), peak head velocity, and peak foot and fist velocities. Data from two existing publications on boxing punches and taekwondo kicks were compared. METHODS For taekwondo head impacts a Hybrid II Crash Dummy (Hybrid II) head was ins...
We consider the problem of contact interaction punches various shapes with an elastic foundation modeled by layer two bedding coefficients. The application this model makes it possible to determine not only stress states punch and but also their displacements. perform numerical analyses compare results obtained for different models foundations punches.
Literature to support the chemopreventive potential of several bioactive molecules has been prolific and convincing, but the clinical development of these agents has been slow. Major hurdles for development of bioactive chemoprevention approaches include low potency, lack of reliable formulations with high bioavailability that are suitable for oral administration, and relevant preclinical prima...
An activity profile of competitive 3 × 2-min novice-level amateur boxing was created based on video footage and postbout blood [La] in 32 male boxers (mean ± SD) age 19.3 ± 1.4 y, body mass 62.6 ± 4.1 kg. Winners landed 18 ± 11 more punches than losers by applying more lead-hand punches in round 1 (34.2 ± 10.9 vs 26.5 ± 9.4), total punches to the head (121.3 ± 10.2 vs 96.0 ± 9.8), and block and...
Coaches and athletes need to understand the kinematics dynamics of karate kicks improve training process results. The research was aimed at studying automatic recognition punches in using only linear acceleration sensors. Accelerometers were part Inertial Measurement Units (IMUs), which attached left right wrist athlete. To develop a model punches, highly qualified with 3-7 years experience par...
Let A be a set of trivariate irreducible integral polynomials and let D be an A-invariant cylindrical algebraic decomposition (cad) of three-dimensional space. This paper presents a new algorithm for determining the interstack adjacencies in D over a given non-nullifying (for A) 0-cell, 1-cell adjacency in the cad D 0 of the plane induced by D. We show that this new adjacency algorithm for thre...
