Composición corporal y mineral óseo en gimnastas femeninas pre- y peripuberales
La actividad física puede modificar la composición corporal y la mineralización
ósea. Se compararon ambas variables en gimnastas femeninas de competición
y controles apareados por edad y sexo que realizaban gimnasia recreativa (n =
12 en cada grupo; edades 9 a 14 años).
La composición corporal se evaluó por métodos antropométricos y
densitometría de rayos X (DXA). El contenido mineral y la densidad mineral
óseas se midieron por DXA en cuerpo entero y columna lumbar. La ingesta de
calcio se estimó por encuesta.Body composition and bone mineral in female pre- and peripuberal elite

Intensive training may influence body composition and bone mineral. Highly
trained female gymnasts were compared with age-matched girls exercising for
leisure.Fil: Saraví, F.D..

Lattice Theories with Nonlinearly Realized Chiral Symmetry
We present the lattice formulation of effective Lagrangians in which chiral
symmetry is realized nonlinearly on the fermion fields. In this framework both
the Wilson term removing unphysical doubler fermions and the fermion mass term
do not break chiral symmetry. Our lattice formulation allows us to address
non-perturbative questions in effective theories of baryons interacting with
pions and in models involving constitutent quarks interacting with pions and
gluons. With the presented methods, a system containing a non-zero density of
static baryons interacting with pions can be studied on the lattice without
encountering a complex action problem. This might lead to new insights into the
phase diagram of strongly interacting matter at non-zero chemical potential.Comment: 3 pages, Lattice2003(chiral
Efficiency in sequential testing: Comparing the sequential probability ratio test and the sequential Bayes factor test
In a sequential hypothesis test, the analyst checks at multiple steps during data collection whether sufficient evidence has accrued to make a decision about the tested hypotheses. As soon as sufficient information has been obtained, data collection is terminated. Here, we compare two sequential hypothesis testing procedures that have recently been proposed for use in psychological research: Sequential Probability Ratio Test (SPRT; Psychological Methods, 25(2), 206–226, 2020) and the Sequential Bayes Factor Test (SBFT; Psychological Methods, 22(2), 322–339, 2017). We show that although the two methods have different philosophical roots, they share many similarities and can even be mathematically regarded as two instances of an overarching hypothesis testing framework. We demonstrate that the two methods use the same mechanisms for evidence monitoring and error control, and that differences in efficiency between the methods depend on the exact specification of the statistical models involved, as well as on the population truth. Our simulations indicate that when deciding on a sequential design within a unified sequential testing framework, researchers need to balance the needs of test efficiency, robustness against model misspecification, and appropriate uncertainty quantification. We provide guidance for navigating these design decisions based on individual preferences and simulation-based design analyses
The simulation of aerial movement—IV. A computer simulation model
A computer simulation model of human airborne movement is described. The body is modelled
as 11 rigid linked segments with 17 degrees of freedom which are chosen with a view to modelling
twisting somersaults. The accuracy of the model is evaluated by comparing the simulation values
of the angles describing somersault, tilt and twist with the corresponding values obtained from film
data of nine twisting somersaults. The maximum deviations between simulation and film are found
to be 0.04 revolutions for somersault, seven degrees for tilt and 0.12 revolutions for twist. It is shown
that anthropometric measurement errors, from which segmental inertia parameters are calculated,
have a small effect on a simulation, whereas film digitization errors can account for a substantial
part of the deviation between simulation and film values
