Hello, I just turned 47 myself. My training is still specific to hockey, in the gym. Old habits I guess. But I have to say that I’ve changed a few things in the more recent years that have allowed me to go on essentially unimpeded with the same type of programs I used as a younger man. 1) I put a lot more effort into the recovery phase, with thorough yoga stretching pre and post workout. Hydrotherapy as often as I can. Continuous research into how to best help a body recover. Knowledge is power. 2) while I’ve kept the same level of intensity — increased it even — my overall volume of work is lower. Just as an example, I don’t do 6-8 sets of deadlifts anymore. I just pyramid up with three, the third being a 4RM. 3) I have altered my diet greatly from being a super high meat protein diet, to being a 95% vegetarian diet w/ just 5% meat protein, eaten one of every 10 meals approx. This type of pseudo-vegetarianism has changed the way my body manages energy, and that is per some of the latest science, that isn’t entirely popular as yet. I tried it just to see if certain claims would come to fruition, and I’ve found that they did. My endurance energy level has gone through the roof. I have yet to determine the detriment to muscular hypertrophy/hyperplasia, but I suspect there is one that I hope to find a way to mitigate. 4) I now also practice time restricted eating on a daily basis, where I don’t consume any food other than coffee from wake up until about 8-9 pm. It sounds odd, but once my body acclimated to this tactic, I am no longer hungry or interested in food for the duration of my entire day, despite the fact I usually do one strength/conditioning workout session in the morning, and one plyometric, or on ice work out in the after noon. I just don’t start getting hungry until around 7. And I’m left with more than sufficient energy for a whole day of activity. It feels weird, in a good way. It’s like, for a whole day, my body never has to switch from musculoskeletal blood flow into digestive system blood flow. And I feel more energetic thought the day because of it. Makes u realize that eating often throughout the day means your body has to keep diverting resources to and from systems other than the musculoskeletal system, which is obviously less efficient than just doing the switch once per day.
All these things I’ve made part of my training as a 40+ athlete, come with better results than that which I saw even in my earlier decades. Some of these things weren’t even understood when I was 25, or, 35. So we’re lucky actually. We got older but science got better, and we can benefit from that. I highly recommend exploring some of these. And good luck to you.
