4 Major Challenges as Highlighted By our Deputy Prime Minister
Saturday, May 6, 2023
Hypoxic Training ; Controlled Environment with Low Levels of Oxygen ; Scientific Studies and Results in Post Here
The data and research done by Sports Scientists, Professors G. Millet, B.Roels,L.Schmitt,X.Woorens et al from multiple universities such as Institute of Sports Sciences, University of Lausanne, Switzerland etc. is quite comprehensive.
There are typically 4 different types of key studies :
a) Live High Train High
b) Live High Train Low
c) Live High Train Low and High
d) Live Low and Train High
All these studies are as a result of the near miraculous performances of many athletes who participated in the 1960 Mexico City Olympics which was held at an elevation of 2250 m above sea level, with it, the air pressure was lower and the O2 level was also lower. Many sports scientists began to investigate the effects such as the increase in haematological capacity, or the blood bearing capacity of the human body, as well as the erythropoeitic effects - the production of more red blood cells when the body is subject to lower levels of O2.
The elite athletes all performed and gave fantastic results (Bob Beamon's long jump record was unbeaten for nearly 25 years after the feat he recorded in Mexico City's rarefied air).
The findings of Millet et al, are shown above, that various combinations of the 4 training strategies DO have a positive effect on the athletes performance when they resumed competition at sea levels. See above graph.
The findings suggest an increase in the level of aerobic capacity optimally 2 - 4 days (green highlights) after return to sea levels, but this is not 100% for all athletes.
From 14th to 28th day after the LHTH trainings, the effects are still apparent as seen from the graph (Orange highlights in graph).
Hence, it justifies the benefits of this type of training strategy.
QRA's Athletic Environmental Chamber can simulate altitudes with Oxygen levels up to 5000 m (O2 level of 13.5% or lower). Additinally, QRA can provide Sleep Rooms with altitude levels of up to 3500 m and corresponding O2 levels to match.
Hence, the LHTH, LHTL and the other configurations can easily be accomplished at sea levels without the need to move the entire set of athletes, nutritionists, physiotherapists, doctors and scientists to migrate for weeks to higher altitudes in the name of better performances.
We can provide the full suite of environments, in the Environmental Chamber in your building, anywhere in the world.
Temperature : - 20 C to 50 C
RH : 20 to 95%
Hypoxic : Sea Level to 5000 m
CO2 : maintain at 400 ppm
Solar : Entire Solar Spectrum.

Every Adult Should Know This (from the Science of Sleep) ; The Sleep / Wake Cycle
The below text is adapted from the book, the Science of Sleep (Author : Heather Darwall Smith, June 2021). Its a game changer for anybody who wants to perform at their best, sleep is the No. 1 activity to engage, before nutrition and before exercise.
Without a good night's sleep, we can behave like "The Walking Dead" devoid of any logical, emotional nor cognitive thought. How many hours we need each night ? Well like they say in the movies, "the jury is still out" on this but most people need 7 hours on average. Some need only 5 hours and some need 9 hours, so this varies from person to person, as well as the age of the person.
The Sleep / Wake Cycle
Our sleeping and waking hours are regulated by 2 Biological Processes that work in tandem. Our Circadian (circa Latin "about" and dies Latin "day") rhythm. The circadian rhythm also known and Process C regulates our sleep as well as numerous biological functions of our body. Better known as our 'Body Clock', the rhythm keeps our body in-sync with the day, our moods, our sleep and our energy. Its like a sinusoidal cycle with one peak an one valley every 24 hours.
Our homeostatic sleep pressure, or Process S defines our urge to go to sleep. The longer we stay awake, the greater the build up of this Sleep Pressure or urge to go to sleep becomes.This build up as far as we know, is due to the accumulation of the chemical called adenosine. This chemical which is naturally secreted in our bodies (unless you have degenerative brain diseases like Parkinson's or Dementia). Adenosine build up causes drowsiness and hence we fall asleep. The rise and fall (or Cliff Effect as shown in the picture above) is called Process S and it supposedly occurs EVERY SINGLE DAY.
This rise and fall of the sleep pressure is called the Homeostatic Process. or Process S. Process S looks like a Cliff rising from the low in the morning at 7am (almost no adenosine) till about 11pm that same evening.
Wait, not so fast.
Process S by itself is not sufficient for anyone. It needs to coordinated with our Circadian ryhthm, or Process C. This ryhthm is like a sinusoidal curve, peaking at around 2pm, and then gradually drops down - way down till our energies are at their lowest at around 11pm. The "Sleep Gate" or the doorway to the Sleep Zone opens. Therefore, our Sleep Clock is in fact the interplay of 2 Graphs, the Homeostatic Process and the Circadian Cycle. At roughly 11 pm of our local time - wherever we live at for a prolonged duration of time - 2 things happen AT THAT TIME.
a) The Process S Homeostatic Process where the adenosine levels are at their peaks, and hence the drowsiness of the person is at his peak.
b) The Circadian Rhythm is at its lowest, and the Sleep Gate is right at the bottom, and opens, hence triggering the sleep inducing hormone Melatonine. Your energy levels will first stabilise, and then build up as you sleep.
As morning approaches, Process C triggers the Alertness hormones Norepinephrine, which are essentially neurotransmitters in our brains and spinal cords. Norepinephrine increases alertness, arousal and attention and is so crucial for everyday functioning.
Hence the 2 Graphs ideally must work in Unison for anyone to be at his best during the day.
Regulating the Sleep / Wake Cycle - a Neurotransmitter called Orexin
The mechanisms which move us from wakefulness to sleepiness and then sleep is known as the 'flip-flop' switch. A system that controls the brain circuitry via 2 nerve cell groups. One group wakes us (the Norepinephrines) and the other sends us to sleep. The flicking of this On-Off switch between wakefulness and sleeping is controlled by this neurotransmitter called Orexin.
If this neurotransmitter Orexin is damaged by brain injury or Orexin levels are too low, such as those with Narcolepsy, the ability to move between sleep and wakefulness becomes unstable leading to a range of sleep disorders which can be potentially life threatening or diminishing one's quality of life severely.

Our Healthcare System ; Stating the Obvious ; Why no preemptive measure when all the studies point to a Super Aged Society ?
I read with dismay today that almost all of the Government Hospitals have waiting times of up to 4 days for patients with urgent medical conditions. I am horrified that the system and the management of this major issue is taking a 'reactionary' stance. With 2 over years of stagnant work from home arrangements, and we are caught in a 'deer in headlights' situation of not pre-empting this issue.
While no one is denied prompt medical attention, the fact that we have been experiencing a bed crunch for the last 3 - 4 years with no plans or apparent plans to build new facilities is UNACCEPTABLE.
There is ample budget each year for Health Care, so why is our Government sitting like a lame duck ?
Hey, the Minister is being paid millions of dollars a year !
The Perm Secretary is being paid probably over a million dollars are year !
And all they can do is highlight the problem ?
This is not the type of Government I would expect from such highly paid and so called competent and efficient civil servants.

Elitism ; a society ruled
ASICS 'ELITE' CROSS TRAINER
Elitism is the belief or notion that individuals who form an elite—a select group of people perceived as having an intrinsic quality, high intellect, wealth, power, notability, special skills, or experience—are more likely to be constructive to society as a whole, and therefore deserve influence or authority greater than the common man.
Singapore has had a superb run .Since its founding on August 9th 1965, Singapore the island nation of then 3 million made up of mostly poor migrants from China, India and the indigenous Malay people with a then per capita income of equivalent to Kenya, has over these past 58 years made great strides in improvements to its citizens well being. We are currently 4th highest GDP per capita (close to US$ 100,000 per citizen) and have one of the world's highest standards of living.
We all know and are thankful to the first generation of world class leaders of the ruling People's Action Party helmed by the brilliant statesman and leader Lee Kwan Yew. His passing 8 years ago has led us to believe that the years of super high GDP growth (more than 10%) is but a memory.
As a developed society (Singapore became a developed society in the earl 2000s), I believe that the following values are well entrenched in our midst :
a) multi-culturalism
b) multl- religiousness
c) abiding to a fixed rule of law
d) Separation of the 3 entities of Government, namely the Executive, the Legislative and the Judiciary.
e) a free and fair election of Government every 4 to 5 years as mandated in the Constitution.
As a result over the years of rapid economic and social standing growth, there has developed an elite class or people who by virtue of their status, have a better chance of 'making it' than the other class or 'working class'.
The gentry or people who have achieved financial independence very early on in their lives, and are living in good class bungalows and / or in Sentosa island. Well good for them. Should the nation's leaders come from only this class of people ?
I say 'No'. The Government should be made up of elected citizens who go through the lengthy and tedious process of serving the country first and foremost. By working at the grassroots level, the major prerequisite for our elected leaders must be they must be :
By the People (elected)
For the People (serve the people first and foremost)
and Of the People. (from the people - every segment)
So while the gentry MAY be Of the people, how do they know or even experience the plight of the working class ? It is only partially true.
Do they feel the pain of inflation at all ?
Do they EXPERIENCE the issues of those living in rental flats ?
Have they actually spent their time serving the people first before they actually are voted in, to formulate policies for the people ?

Bedok South Market and Neighbourhood 23 April 2023
Last Sunday, 23rd April I went to Bedok South market to run some errands, and I was so pleasantly surprised that the neighbourhood is thriving what with the wet market at one end, the cooked food hawker centre, 1 clinic, 1 dentist, the 2 Chinese medicine halls, and lots of convenience stalls (3 bakeries, 3 fruit and vegetable stalls, 2 hairdressers, clothing stalls, snacks, 3 banks ATMs, several coffee shops and the Prime Supermarket - all within the 800 x 1000 m rectangular district centre.
There is even a Neighbourhood Police Post to ensure law and orderliness.
What convenience ! All within a short walking distance (5 to 10 minutes) from at least 20 blocks of HDB flats This scene is replicated in multiple satellite towns all over the island.
This is the one thing I truly miss, as I have not lived or managed to stay in a Government managed estate in all of my (X0) years.
Singapore with its emphasis on productivity, convenience, safety and ease of connectivity has it all.
The not quite 'village' lifestyle is apparent when you step out from your flat and into the common corridor. Take the lift downstairs your block and within minutes, you have everything you could possibly want.
Singaporeans have arguably the best (managed and highly developed) housing program in the world. 80% of all citizens live in public housing and the reasons apart from affordability, are what I just described in the paragraphs above.
Each flat which you and your spouse purchases (one party must be Singaporean) is heavily subsidised but you need to have a minimum occupancy of 5 years before you can rent it out or sell it completely. It is called MOP. Many SIngaporeans have benefitted from this asset appreciation hugely, but there are many differing points of view about the profiteering of an asset class which is not owned by the individual citizen.
As a result, the ever spiralling costs of resale flats in the last 10 - 15 years have made living and retiring in Singapore an expensive 'dream'.
