that what wife said..
i still did a short 50mins easy run. imho not that bad.. pretty minor.
my eyes usual will feel dry and teary when the air is really bad

...running will inhale so much air and more PM2.5 residue will get trapped inside your lungs then normal breathing and forever accumulate there

better dont run. not worth it

I probably will sign up later, might go for 15k instead. I need to solve my early morning GI issue when running


It’s quite significant, and also goes to show that those who aren’t as fast (weaker leg strength) have a lot more to benefit.

18s off 2.4km at high 7 min pace, has a lot more translation to longer distances, at least a min off 10k time.

I have done jumps in stadium before (max = 150), massive hamstring gains. Will be interesting to try this out.

Maybe can pace u if u do 15k haha but u prob faster for this shorter distance!

NEA say 1hr pm2.5 is in the normal range. 24hr PSI is also in the good to moderate range.
imho can still continue with normal exercise regime unless there are underlying health concerns.

crazy to run outdoors in hazy days
do more harm then good for ur body

did feel the air isn't too good, throat feeling something during my run this morning.

From my app, there was a spike around 8am to 9am. In general most of the day the AQI is good.

trust own nose lor
last time I iron teeth go run liao then sore throat, cough etc...not worth it. probably i am the sensitive group

its about relative difference. Coming from deep winter (av. low single digit degC) dry cool air of below 100 aqi, probably does have a difference on me as well.
all these metrics are just scientific justifications only. How one feels is subjective. We have to take care of ourselves.

 

[GlassDoor]

good time as any to start practicing nasal breathing.
i think intensity of exercise also plays a part as well.
Will i go on a VO2max workout today? highly unlikely.
But for easy effort runs I think no diff.

...running will inhale so much air and more PM2.5 residue will get trapped inside your lungs then normal breathing and forever accumulate there

actually. what you said is not true.
the dangers of pm2.5 particles is that it is too small to filter and will enter the blood stream.
but again me not doctor....

Time to run treadmill ? Dun like it , unless during overseas work trip

I posted in the Consolidated haze thread. Yeah quite smelly last night at my place Tg pagar.

My laser particle meter was reading 60-65 ug/m3 spot reading at around midnight time. Coz of the high humidity and the fact that i do not dry the intake air (it's just a simple IR laser laser particulate meter with some algo running ), this is an exaggerated number, normalized would probably be in the 40+ ug/m3. Or around AQI 125 thereabouts.

This laser particulate meter is still somewhat sensitive to 0.1 to 0.3 microns tissue paper smoke, i tested before....only thing is, the levels probably would be lower than in reality, but still with sufficiently high levels, it can detect one. Coz I use it to test KF94s last time during covid for the folks here @ HWZ. And before that for play play during the 2015 and 2019 haze episodes.


56 ug/m3 is AQI 150, equivalent to "1hr" reading of PSI 100. That is based on NEA's 1hr PM2.5 reading (not my meter)

But these are just at that moment in time spot readings on a personal scale/basis.

If wanna be more accurate, need to get the intake sampling air down to RH% 35.
BTW, NEA samples from several measuring sites and that is averaged. So also not say very representative of what your area is experiencing coz for very nearby sources (ie Pasir Gudang), it has been shown on satellite pics that the smoke plume is usually a very narrow cone. Possibly say at Punggol, it is just a few km wide only.

Bro tmkedmw got lots of details in the haze thread, those interested can take a look.

So we should nua at home like u ?

Anyway runners are known to have higher rate of nose rhinitis (check Exercise induced rhinitis) than sedentary due to higher rate of breathing when we exercise. Basically we are exposed to pollutants more than people who don't exercise even when the air is clean. The paradox, runners have better respiratory and cardiovascular system than sedentary people. But do we run in mild haze? Up to you, Personally, light smell I will run, coz these few weeks, I know that the smell will go away when I run to another spot. Mostly is no smell.

> 100 aqi, it's smelly. This is no running for me.

 

[ctstalin]

Will still go and run unless the air is at super unhealthy level. Today one sup sup water lah. Not ideal, but it is what it is

 

[WussRedXLi]

did feel the air isn't too good, throat feeling something during my run this morning.

Oh, then this morning my meter showing around 40 ug/m3. Vs 60-65 last night. Dont think the relative humidity % that much different. So got improvement ba. Actual more accurate levels would not be over 30 ug/m3, or not more than AQI 100.

But this smoke sure has pungent smell. Not sure if it is from the peatlands near Kota Tinggi area, that area is much smellier than the smoke haze from Sumatra. Kalimantan haze usually lesser smell.
Not sure if distance also has to do with it (some decay mechanism over longer distances or something)........even though all are so-called peatland fires.

But now South side no more, from just now i came out for lunch, not sure where the smoke plume changed direction to....... heh. Basically the narrow smoke plume just shifts around, that is why 1 fella in the haze threads here say super smelly, then another would say POFMA you, where got, zero here. Standard for Johor haze lah coz we are so close. (I try to find picture).


Peat land fires terribly difficult to extinguish one, usually is just wait for mother nature.

Oh found it...... the plume would expand more and more as it gets further and further. Sometimes also depends on atmoshpheric conditions, whether the smoke gets lifted up further into altitude, or some inversion layer keeps it close to the ground.
That's why sometimes the sun like very orangey, it's the smoke up there, but ground level is clean air.

> 100 aqi, it's smelly. This is no running for me.

Actually still can run ba esp short distance..... but yeah, usually the Kota Tinggi area peatland fires just S of Mersing rather smelly one. heh.....

But some are quite sensitive to smell, will get headaches. Is prob some sensory trigger or something.
Might be a bodily defence mechanism, based on neuro memory from 1997, 2013, 2015, 2019 haze episodes also. Sometimes these things quite funny one, the brain remembers one, and if one is paritcular susceptible and sensitive, will trigger even based on smells. Of coz, just somewhat harmless symptoms though irritating.

For those esp super susceptible, can even trigger migrane, and migrane already trigger vomitting. Got this wierd brain-gut axis thingy, my kid got. Simple running nose, sore throat, can trigger migrane, then migrane will trigger GI issues and vomit, and so the stomach buay song liao trigger more migrane, and more migrane trigger more vomitting. Run away chain reaction. Once even went to Mount Elizabeth midnight time, emergency CT scan in order to rule out serious conditions like meningitis, coz every 15-30 mins vomit, which can turn very very serious in rare instances if continued . That 1 single day we visited 2X GP gave suppositories and all those (constant vomitting = no oral meds, wont work) and then midnight sent to Mount E.
Source? Just a simple flu or cold nia. Costed me 6k, but heng got full Prudential insurance.

But as far as for heart issues triggers, the levels are low.

AI :
The vagus nerve is the primary bidirectional, physical conduit of the brain-gut axis, acting as a crucial, fast-acting communication pathway for regulating digestion, immune responses, mood, and metabolism. It transmits sensory information from the gut (microbiome, nutrients) to the brain and sends motor signals back, playing a key role in inflammation control and stress management.

Yeah I still remember, basket, it took me like more than 1 year to improve my 5k timing at such fast paces when i was super gian at that distance....call it genetic limit or simi limit, not really good at phrasing it. Merely like what....for 60 seconds of improvement, or just 5.5%.

But for beginner stages.......30 min improve to 25 (20%), isnt gonna be terribly difficult.

It's the same for all other things, calisthenic exercises for eg.

I guess as long as it is an area that is still *untapped*, it might be pretty fruitful to tap into it.
Same as what Run Elite channel says, if a runner all along never runs VO2max or neuromuscular range (say strides and a wee bit of SIT), you can still expect gains.......simply because it has been untouched.

Of coz, if one's aerobic base and threshold still got rooms for improvement, then this might not be something to really focus on lah. But just assuming that one has already done all he/she can do, be on at least a semi-structured routine, good mileages and recovery routine, not much more room for improvement or squeeze in more hours of training, just to get that lagi small % of improvement.



Side story : Past few months to nearly a year, i really I upped my strength training coz of personal interest there to improve both strength wise and aesthetics wise (not plyo exercises, that one i just do and be done with it coz no real interest. Last weekend i went to Serapong hill sentosa for some climbing test. Around half a year ago i could get up of coz, but must need a fair bit of effort.
Last weekend i went up, albeit rather slowly (slower than usual), but the HR was so low, plus i felt almost "floating up", coz the muscular strength needed was not anywhere my limit.

Somemore what i have been doing just "merely" mike mentzer's HIIT style, 1 warm up set (eg dips only do 5 reps, very little warm up even) and 2 workout sets, one of which is hard and 1 all out, hit failure and then shake it out before bashing out some more reps, and lastly shake it out again to clear lactate, then all out till the last rep you might only be able to hold it half rep isometrically and shaking for 5-10 seconds.
DOMS is not a good indicator of training effectiveness for muscles but i quite often get that, then i'd make sure i recover well (3 days usually) before embarking on next session.
I know for my age, i do daily. confirm is walk forward 5 steps walk backwards 4.8 steps one and plateau after a certain stage coz the high reps i cannot confirm i hit a hard enough level of stimulus in training, maciam doing for the sake of doing only.

Young chap here doing Serapong. It's not as long as Lor Sesuai @ Bukit Timah rd (that one popular with runners) but there is a certain part at the first 1/3rd that is !!#%@@#!@# steep, i believe even steeper than Sesuai. Beginners wo leg strength for sure "fall" one, and after falling then good luck....no need to mount and pedal liao coz too steep to restart.

I plan to alternate box jumps and drop jumps to get the best of both worlds.

The workout is 60 sets so I will do 6 x 10 sets of box jumps and drop jumps (3 sets of each). The rest within sets is 15s and between sets is 2 min. Do it twice a week.

Most likely do it after easy run instead of before the run.

Just for the fun of it, I plan to bring a ruler to measure the stadium jump height.

Maybe can pace u if u do 15k haha but u prob faster for this shorter distance!

I am not too sure if my GI issues will emerge during the race. But I will have to get in early morning race pace workouts.

I have done empty stomach workouts at 4.13-4.14 min/km 12k without any issues at 8am. But 5.30am is a different story.

Not too sure if the headache from waking up earlier cause my GI issues.

64 mins > possible aim even if feeling bad since I managed to run 65 mins in HM

63 mins > realistic aim if assuming some hiccups in execution

62 mins > perfect/miracle day, I don’t see myself running sub-62

Time to run treadmill ? Dun like it , unless during overseas work trip

Go for it, if u are uncomfortable with the smell

 

[WussRedXLi]

Siao boh.......2pm heat can run that pace (fastest 35:04 min for the 10k but based on Aaron's GPS it is like 0.7km short heh...but still), and at that age grp of 40-49. Based on experience, that kind of temperatures, even 5min/km pace i might have trouble holding coz basically i'd just overheat and feel unwell first and pengsan later if go faster....or just hit the MHR wall even with comparatively low RPE.

true. We have to take care of ourselves based on own's reactions. for me, i cannot use empirical data to judge as i have a pneumonia history that has made my respiratory system more sensitive than others. How I feel is more critical than raw generic data. Whether relative feel makes a difference am not sure, just a guess. My bad to talk about relative feel instead of personal reaction.
