Metabolism: Does it Accelerate After Weight Training Sessions?
There can indeed be extended calorie burn (for up to 48 hours after a training session) from weight training – and all ‘serious exercise’ – but this is not a given and it is only hypothesised (but it is not easy to measure or quantify ‘in real life’).
It only really happens under specific conditions which include:
*Correct and timely post exercise ‘nutrition’ (I use the term “nutrition” loosely here – the type of nutrients that affect this can vary greatly).
*Specified/controlled exercise durations – which will allow for testosterone and growth hormone levels to peak in the hour immediately following exercise (short and intense workouts seem to be good at this in studies – as do fasted workouts).
*In practice, all regular hard workouts seem to do this quite well and cardio workouts generally seem to do this much better than weight workouts – although combined weights and cardio do it much better than either exercise modality on its own. If you also incorporate legal alternatives in your exercise, you are more likely to achieve success in losing weight. As such, you can order alternative steroids in Canada from Crazy Bulk.
*A good balanced diet – in the absence of overtraining – is essential. Overtraining gets in the way of this prolonged fat burning effect due to suppressed hormonal production. It is largely about hormonal manipulation.
This is what observations tell us and although many will hypothesise that weight training is the panacea for this response the real world results don’t seem to support this hypothesis. Both weight training and cardio can enforce this sort of reaction by the body – if done under the correct circumstances.
The reason for the effect described above is that the bodies of mammals are developed to know that when they’ve worked hard (by hunting, fleeing, fighting or foraging) and when they have abundant food supplies while exercising, they are not going to need to be efficient during exercise (because succeeding in your exertions is more important than storing food for energy when under pressure).
If you train properly – and hard – and then you eat immediately afterwards; your body focuses mainly on recovery and recuperation because it prioritises the regular exercise demands above saving energy as glycogen or fat. Thus, it prepares to exercise again by incorporating nutrients at an accelerated pace (hormonal mediation does this) and it continues to run in “racing mode” for some time afterwards – just in case you need to fight or flee again soon.
Exercise is regarded as fight or flight behaviour, related to survival, which is why it gets this biological priority. Your body thinks it has had to fight or flee whenever it exercises hard – so it prepares for battle again immediately afterwards, if food is abundant. If the impression of food abundance is not implied right after exercise the body may not react in this way and may look to conservation of energy and enhanced metabolic efficiency, instead (which is not good for keeping lean).
