We evaluated anthropometric and performance measures which best predict bone
mineral density (BMD) in 54 adolescent girls (14.6±0.5y; 22.7±14.0 months past
menarche). BMD for the whole body, femoral neck, greater trochanter, lumbar spine (L2-L4), and mid-femoral shaft was assessed using dual-energy x-ray absorptiometry (DXA)
(Hologic QDR 1000/W). Whole body lean...
Glutathione (GSH) is the predominant low molecular weight thiol antioxidant
in liver tissue. GSH plays an important role in maintaining the intracellular thiol redox
ratio as well as detoxification of electrophiles and xenobiotics. Aging leads to a significant decline (35%; P ≤ 0.05) in hepatocellular GSH levels. Using young (2-4...
The purpose of this study was to identify significant differences
in body composition, body cathexis, and attitudes toward obesity
of women in various age groups involved in different levels of physical
exercise.
A total of 216 women, ranging in age from 17 to 64, took part in
this study. They...
Under certain conditions, a neural network may be trained to perform a
specific task by altering the weights of only a portion of the synapses.
Specifically, it has been noted that certain three layer feed-forward networks may
be trained to certain tasks by adjusting only the synapses to the output...
The back thrust kick is a karate technique used primarily in a
defensive setting. This research described the kinematic
variables involved in the skilled execution of the kick. Variables
examined included movement sequencing, angular position of
the trunk, thigh and leg, angular velocity of the thigh and leg,
linear velocity...
Metabolic syndrome (MetS) and abdominal obesity (AbOb) increase the risk of
developing cardiovascular disease and diabetes. Energy restriction (ER), highprotein
(PRO) intake and high-intensity interval training (HIT) can independently
improve MetS and AbOb. However, ER reduces metabolically active lean body
mass (LBM) in addition to body fat (BF). Purpose: To...
Despite dramatic changes in tennis equipment and technique, more than 30% of
recreational tennis players suffer from lateral elbow pain ("tennis elbow"). Certain
kinematic and electromyographic characteristics in backhand strokes have been
implicated as major factors responsible for lateral elbow pain. From a local tennis club,
22 recreational players who...
