Views of adolescent female youth on physical activity during early adolescence
Physical activity female youth qualitative
2015/5/8
Early adolescence is a time when a transition away from sport
and physical activity participation is at its highest level among
female youth (Hedstrom & Gould, 2004). This has led to the
identif...
Short-term jump activity on bone metabolism in female college-aged nonathletes
Kohei Kishimoto Ryan P. Lynch Jamie Reiger Vanessa R. Yingling
2015/5/8
There have been few studies examining the short-term effect of
high-impact activities on bone metabolism measured by bone
serum marker concentrations. The purpose of this study was to
examine th...
Daily Physical Activity and Physical Fitness in 11-to 15-year-old Trained and Untrained Turkish Boys
Physical activity training aerobic and anaerobic fitness body fatness children
2015/5/7
The aims of this study were to assess levels and patterns of physical activity (PA) in relation to age and regular sport activity, and to examine its relationship to physical fitness in trained and un...
The Effect of Whole-Body Vibration Frequency and Amplitude on the Myoelectric Activity of Vastus Medialis and Vastus Lateralis
EMG vibration training whole body vibration (WBV) muscle activity
2015/5/6
The aim of this study was to evaluate the efficiency of training protocols for whole body vibration (WBV) training through the modulation of the frequency and amplitude of vibration. Despite the large...
Changes in Quadriceps Muscle Activity During Sustained Recreational Alpine Skiing
Muscle coordination recruitment electromyography wavelet analysis
2015/5/6
During a day of skiing thousands of repeated contractions take place. Previous research on prolonged recreational alpine skiing show that physiological changes occur and hence some level of fatigue is...
Seasonal Differences in Physical Activity and Sedentary Patterns: The Relevance of the PA Context
Season accelerometer physical activity context
2015/5/6
The aim of this pilot study was to characterize seasonal variation in the moderate to vigorous physical activity (MVPA) and sedentary behavior of Portuguese school youth, and understand the influence ...
Determination of an optimal threshold value for muscle activity detection in EMG analysis
Electromyography cycling incremental exercise
2015/5/6
It is commonly agreed that one needs to use a threshold value in
the detection of muscle activity timing in electromyographic
(EMG) signal analysis. However, the algorithm for threshold
determin...
Study of Day, Month and Season Pedometer-Determined Variability of Physical Activity of High School Pupils in The Czech Republic
Day-to-day variability physical education adolescents school year pedometer
2015/5/5
Long-term day-to-day monitoring of physical activity (PA) has not been undertaken in adolescents despite PA declines rapidly during adolescence. This study monitored the school year-round pedometer-de...

Autonomic nervous system heart rate variability power spectral analysis
2015/5/5
This study evaluated the synergistic effects of acute exercise
with capsaicin (200mg) upon the restoration of cardiac autonomic functions and depolarization-repolarization interval as
well as subs...
Intensity and timing in life of recreational physical activity in relation to breast cancer risk among pre- and postmenopausal women
Exercise breast cancer case-control study
2015/5/5
Regular recreational physical activity has been found to be
associated with a decrease in breast cancer risk in women in the
majority of epidemiologic studies, but research findings are
inconsis...
Effects of warm-up on vertical jump performance and muscle electrical activity using half-squats at low and moderate intensity
EMG contrast training resistance exercise
2015/5/5
The purpose of this study was to determine the effects of a
specific warm-up using half-squats at low and moderate intensity on vertical jump performance and electromyographic activity of the thigh ...
