unexpected results@Guardian
Scientists often think the public will believe anything when it comes to
new research, but studies show that this viewpoint is unproven

finally...
i have submitted PhD thesis today.
it was nearly 3 years of hardworking.
the story of my thesis is:
1. individual differences exist in response to elite athletes' conditioning (training + recovery activities)
= used single-case research designs
2. their training load, recovery, performance, and performance readiness are fluctuating daily
= used randomization tests to analyze mean differences between training phases
3. the fluctuation has trends
= used time series analysis (e.g. ITSACORR)
4. coaches and sports scientists want to predict athletes' performance and performance readiness
= used mathematical models (e.g. dynamic factor analysis and structural equation modeling).
i strongly believe my approach will change the way we assess elite athletes' conditioning.
it's not over yet (needs 2 months of thesis examination),
but feels great to accomplish something really BIG!
thank you all for your support.

juggling alters the structure of human brain
nature 427: 311-312, 2004
the subjects showed a structural change in brain areas that are associated with the processing and storage of complex visual motion after 3 month of training

what makes a champion swimmner?
talent identification
short distance: tall stature and long segment lengths
breathstroke + long distance: the shorter and stockier body builds

what is science?
science is the organized, systematic enterprise that
gathers knowledge about the world and condenses
the knowledge into testable laws and principles
(Edward O Wilson)

research processes
1. observation of the facts demonstrated, based on methods that are decisive, clear, and highly precise
2. experimentation, which creates new conditions for observing the phenomena
3. criticism and elimination of erroneous hypotheses, and elaboration of a rational interpretation of the facts
4. proof of the hypothesis by new observations or repeated experiments
5. replacement of the hypothesis
6. applying the implications of the hypothesis, now regarded as established , to other spheres of knowledge
(Ramon y Cajal "Advice for a young investigator")

training facilities for elite athletes
I went to Sleeman Sports Complex@Chandler (17km from Brisbane) to see a training camp of AIS divivers. I met athletes like Mattew, Robert, Lynda (all are medalists) and Mary@Excective Director. They were all very nice people.
Also, I visited Sports Super Centre@Gold Coast. The facilitiy is very modern and has airy spaces. Best place for a training camp!

multidisciplinary approach for future research
Comp Biochem Physiol A
Dr Myburgh's review. multiple factors are essential contributors to world-class endurance performance. sports scientists should work with biomedical engineers to develop biomolecular sensers for non-invasive monitoring.

fatmax: a new concept
Eur J Sport Sci
Dr Jeukendrup's short review. fatmax = the exercise intensity at which maximal fat oxidation is observed. fatmax may be used in weight-loss programs, health-related ex programs, and endurance tr.
