So when thinking about the effects of sport training on children, we must appreciate that adult-organized programs are superimposed on a constantly changing base. To what extent can athletic training accelerate the normal improvements in physical performance of children and adolescents as they grow (that is, beyond the stimuli provided by Mother Nature)? Are there critical periods when children are optimally sensitive to improvements associated with instruction and practice (in the case of ...

Athletes do their best to realize their genetic gifts and hard work in just a few clicks of the clock called competition. This phenomenon is seen through moments in time that serve to define the essence of sports itself. Athletes are also keenly interested in their repeated performances over time.
The concept of pacing is rooted in the idea that athletes make cognitive, purposeful decisions regarding velocity based on previous experience and sensory input. This traditional model of pacing is rooted in the idea that athletes make cognitive, purposeful decisions regarding running velocity based on previous experience and sensory input. For instance, Yumna Albertus and her colleagues at the University of Cape Town shamelessly deceived trained cyclists during 20K time trials to see if ...
In athletes, stride rhythm is often coupled with breathing while running, walking, cycling, or rowing. Experienced runners commonly coupled stride and breathing patterns very tightly. The most common ratio was a 2:1 ratio of strides and breaths, but at slow running speeds, this was frequently 4:1. However, in less talented runners, no synchronization of breathing and striding was observed at all.
We take a closer look at studies into the effects daily activity and caloric restriction have on animals, and what the results might mean for humans. Compared with nonexercising control rats, the running rats demonstrated an average life span that was 9% greater (1009 ± 132 days versus 924 days ± 155 days). At the present time, only two documented means exist of extending the duration of primary aging—calorie-restricted diets and genetic manipulation.
Now author Tom Rowland, MD, is giving athletes and coaches a better understanding of and appreciation for the intricacies of human potential in his book, The Athlete’s Clock: How Biology and Time Affect Sport Performance (Human Kinetics, 2011). Blending physiological, psychological, and philosophical perspectives, The Athlete’s Clock reveals how the central nervous system dictates how fast an athlete runs, how the complex sequence of muscle activation and its tempo can be tuned for optimal ...
Muscle length testing involves elongating the muscle in the direction opposite of its action while assessing its resistance to passive lengthening. Clinicians do not have to perform muscle length testing on every muscle listed; instead, they should assess the muscles that the postural and movement pattern analysis indicate as being possibly tight. Muscle Normal ranges or end feel Iliopsoas 0° hip extension, 10° with overpressure Rectus femoris 90° knee extension, 125° with ...
**Boston Bruins goalie Tim Thomas skipped the team’s visit to the White House to protest the state of American politics. **At least 20 groups submitted bids to buy the Los Angeles Dodgers, with several opening bids reportedly in excess of $1 billion. 2. With owners Fred Wilpon and Saul Katz mired in the Bernie Madoff scandal, the New York Mets’ Opening Day payroll is expected to drop to $90 million from $119 million last season.
