If we train too much, we risk getting injured too. We might not even make it to the game, or the fun run, or whatever event we are training for, because we get hurt along the way. There is, however, a middle ground. We can show this relationship between training load and injury risk as a U-shaped curve. Now, not only does the ability to tolerate training loads differ from person to person, it also changes over time ‘within’ each individual. As we continue training, our strength and fitness improves and we can tolerate more. Try tracking your clients’ training week – both training with you, and on their own. It’s quick and easy to get RPEs and times for all their training. You can use the data you collect to build weekly loads over time, so they can tolerate more and be safer. Injury risk Training load Weekly training load We tend to use weekly totals because it’s convenient, but you can use a different timeframe if it suits your purposes, of those of your client, better. Then we decide how much load we want in a week. Someone doing some light jogging for 30 minutes three times a week at an RPE of 5 will accumulate a weekly load of 450 units. Professional sportspeople, on the other hand, can accumulate weekly loads of over 5,000 units in training and games. Those who want, or need, to do heavy training obviously need to work their way up towards heavy weights, otherwise injury is inevitable. So, what’s the best way to do this? How do we build up training load? Slowly and steadily! When you haven’t trained for a while, the highest risk is early in your training routine. I even see trainers make this mistake in their own training. For whatever reason, they’ve let their own training drop off. Attempting to quickly get back into shape, they go too hard too fast, injure themselves a couple of weeks into their renewed regime and then have to reduce their training again. It’s bad enough to injure yourself in this way, but you need to be very careful not to do the same thing with clients. Always aim for steady increases, rather than a big jump. You may need to educate your clients about this, particularly new ones who have been hit with inspiration and are champing at the bit for their own fast and furious body transformation. If they expect lots of hard training straight away, manage those expectations from day one. Explain to them the importance of building a tolerance first – a foundation on which to build – and that failing to do so will result in them getting injured, stopping training and finding themselves back at square one. Recommendations vary, but I try to keep jumps in training load to less than about 30%. If someone does 1,000 units one week, I look Safe weekly load increase 1800 1600 1400 1200 1000 800 600 400 200 0 Risky weekly load increase 1800 1600 1400 1200 1000 800 600 400 200 0 for no more than 1,300 the next week, then 1,700 the one after that. Of course, goals vary. The footballers previously discussed would average about 2,500 units a week, including their games. For a casual exerciser, however, 1,500 weekly training units might be more appropriate. Once your client has reached the target load you have prescribed them, try to keep them there. Mix up the training type, volume and intensity to keep things fresh, but maintain the load. If they are preparing for an activity that involves high intensities, their training will need to reflect this. For example, footballers and cricketers injure their hamstrings less often when they do small doses of high-intensity sprints regularly at training, compared to when they don’t, even with the same training load. In summary Managing training load is hugely important for reducing injury risk. Don’t do too much too soon. If it sounds simple and obvious, it is – but very few trainers monitor their clients’ training loads in a structured way. For the casual once-a-week client, this might be as simple as slowly building up the weights lifted. For a client preparing for a half marathon, obstacle course or a sporting season, however, you’ll need to spend a little more time programming. Try it and let me know how you go.
