Physiology Made Easy

Hello,

I'm a Senior Lecturer and Clinical Scientist in Cardiovascular Physiology at Bangor University, Bangor, UK, and I have created this channel to provide short informative video tutorials about key concepts in human and exercise physiology, as well as some information on general academic skills. The videos are suitable for all individuals who are interested in the physiological responses to exercise as well as the chronic effects of disease on different organ systems of the body. The videos can be used as revision aids to support your understanding of these topics.

Please feel free to leave comments and feedback under each respective video as feedback will help to improve future videos.

Many thanks,

Dr Aamer Sandoo

    First, I'm so grateful for sharing your knowledge. Next, I want to know that is logical if I run 5k or 10k in VO2max HR zone so that my average HR is about 180? or it is better to train below lactate threshold until move it up?

    You can run in the higher training intensity training zones, but rather than try to sustain it for 5k or 10k, start by having shorter time zones at this intensity with rest at a lower zone.

    Question. For a fat adapted person, do you always require carbs at the anerobic threshold or can we produce high intensity exercises on fat only. I am doing cycling for 4 hrs and i am trying to optimize my nutrition strategy biking at lactate threshold power.

  • @physiologymadeeasy216
    @physiologymadeeasy2162 ай бұрын

    From a physiological perspective, carbs would be the main source of energy at the AT. Fat is a slow burning energy source. It releases large amounts of ATP, but you need to give time for that metabolic process to happen during an event. As soon as you ramp up the intensity, Fat metabolism cannot keep up with ATP demand and the body transitions to CHO use. My suggestion would be to ensure you do have adequate CHO intake if competing in endurance events that require periods of high intensity activity, or even sustained high-effort at or below the AT.

  • @physiologymadeeasy216
    @physiologymadeeasy2162 ай бұрын

    This is a good question. Excessive endurance training can sometimes be detrimental to contact sports as they may impair recovery that then affect other training aspects (e.g. sparring, technical work etc.), so ensuring you have good baseline fitness to compete without fatiguing is going to be your marker. It is likely that in pre-season, you will build up your endurance again (especially after a break), and then you will need to maintain that during the season rather than keep building it at the expense of other training methods. Periodised training (breaking training into short blocks) can help achieve that and prevent over training. Good coaches will also know how to manage the training demands and what level you should be at in different phases, so do listen to them.

    @@omardiangeloarteaga4875 Yes, I agree. If we take boxing as an example, then 4x4 is going to be unnecessary. It would be more beneficial to do a 5k run at a steady pace to ensure you have good stamina. Sometimes, you could increase distance to 8 or 10k. The work at the anaerobic threshold can actually be achieved by intense circuit work or bag work - and it can be argued that those activities are more specific to the sport so better for the boxer. It's always best to follow coaches who appreciate that behind any instruction or approach, there is likely to be a 'science'. They will have much more scope for changing their approach (and opinions) as new evidence becomes available. Hope this helps and all the best with your training and coaching.

    Thank you for explaining all of this so thoroughly! I'm pretty new to running at 60yrs old but have trained weights and martial arts most of my life. I tried MAF/Z2 training for 3 months 3 yrs ago with almost no improvement in my MAF tests at all. After no running for 3 yrs, I have recently started (3mths now) doing short 15 minute runs, 5 times a week at my LT2 HR and have just completed a MAF test to check my aerobic fitness and found I could run 0.6kmh faster throughout than I could after doing the MAF training 3 yrs ago! A question this brings up for me is; other than injury prevention, is there any aerobic benefit that would be better trained in zone 2 more than it would benefit from zone 3 or just below LT2 threshold training? Would LT2 training increase mitochondria and ATP production on a par with Z2 or MAF training? Is there any point to doing Z2 training when LT2 training seems to produce better results for me at the moment? Thank you for any advice.

    What if you’re not a novice and you already had years of leaning a movement, then you come back to a move you haven’t done in a while, does it still take 6-8 weeks for neural adaptation to level off in order for Hypertrophy to occur or would it happen sooner due to muscle memory?

  • @physiologymadeeasy216
    @physiologymadeeasy2162 ай бұрын

    No, I think in this case the neural pathways are set, and it is a much quicker process. Think of it like riding a bike, once learnt you never forget.

    How long does it take to lose neural adaptation to a specific exercise pattern after you learned it?

  • @physiologymadeeasy216
    @physiologymadeeasy2162 ай бұрын

    Unless the movement are very complex, you may not lose the neural pathway at all, however, refinements that are made to the movement with regular practice may be lost and need some training again. For most basic resistance exercises (e.g. squats, bench, deadlifts) you often do not lost neural adaptations for the movement, but you may lose aspects such as firing frequency of neuron to produce maximum force or power.

My blood pressure is in the range of 170 to 180. I am working to reduce fat, particularly visceral. When I go in to the clinic, or dentist, and they measure my BP, it jumps 30 or 40 points. What causes this jump?

  • @physiologymadeeasy216
    @physiologymadeeasy2165 ай бұрын

    @tomranc thanks for taking the time to leave this comment. BP increasing in the clinic is typically referred to as white coat hypertension. One way to avoid it is to ask for a ambulatory blood pressure monitor which you can wear at home and it provides readings over a longer period (typically 24 hours). This will give a much better indication of your BP. All the best with the fat loss journey. Doing some intermittent fasting will hopefully help target the visceral adiposity.

    Yes, and this scientific study confirms that low frequency training (training a muscle group once a week) elicits the same improvements as training the muscle group more than once a week. It is better to utilise the low training frequency approach as you then have a chance to allow the muscle to recover, and minimise cumalative fatigue.

    I believe an important part is missed here. In most individuals the body resting metabolic rate is continuously adjusting according to the energy intake. If energy intake is reduced, this not lead straight away to leanness but metabolic rate will go down, hence the difficulty to lose weight.
