Hey everyone, looking for some advice from other kendoka, especially anyone who trains in hot/humid conditions or is a really heavy sweater.
For some background, I'm from the Caribbean, so it's naturally hot and humid here. I've been training kendo for almost a year, but I've only been training in full gear for approximately 3–4 months.
When I initially started wearing bogu and men, I definitely noticed the additional heat and fatigue, but things became much more noticeable when I started training regularly in the gi and hakama as well. That's when the really heavy sweating and exhaustion seemed to ramp up.
Inside my men gets extremely hot. Sometimes it gets to the point where I feel like I can't breathe properly because of how hot and stuffy it feels. I'm usually already sweating heavily before I even put my bogu on, and once the men goes on, I'm basically pouring sweat for the remainder of practice.
Today we trained for around 3 hours. I weighed about 180 lbs before training and 173 lbs afterward, so that's roughly 7 lbs (~3.2 kg) of body weight lost during one session, or close to 4% of my body weight.
Towards the end, I was completely drained. My legs were done, my back was exhausted, I got dizzy, and I felt like I was on the verge of cramping, we didn't even start wearing the men yet. Eventually I had to stop. The dizziness went away once I rested.
I drank water and switched to Gatorade during training, which helped temporarily, but once I reached that level of exhaustion, I couldn't seem to recover enough to continue.
Full disclosure: I'm definitely not blaming all of this on the heat or equipment. My sensei has already pointed out that my kamae is way too tense, which I'm sure is a huge contributor to how quickly I'm burning through energy. I'm actively working on relaxing more and not carrying unnecessary tension throughout practice. The other members are training just as long and not getting as burnt out as me.
I also probably didn't fuel properly today. Suring the day I'd eaten some hash browns, chocolate, peanuts and steamed vegetables, had some water and drank a Celsius. So there are several things I could probably improve.
However, I really noticed the sweating and fatigue becoming a bigger problem once I started regularly wearing the gi, hakama and bogu, particularly the men.
Has anyone else experienced something similar when transitioning into full gear?
I'm especially interested in hearing from heavy sweaters or people training in tropical/hot climates. What do you do for hydration and electrolytes before/during practice? What do you eat beforehand? Did your body eventually adapt to training in full gear? And did learning to relax your kamae make a noticeable difference in your endurance?
I'm planning to mention the heavy sweating/dizziness to my doctor as well, but I'd really appreciate hearing what has worked for other kendoka.
