What you're really asking for is insight into the strengths and weaknesses of Aikido pertaining to self-defense scenarios. Aikido uses a small number of throws, joint locks, submissions, and strikes. There are some holds and submissions done from the ground. A number of breakfalls are trained. There is some weapons training as well, notably the 4-foot Jo ...

At first glance Krav Maga and Systema seem to be very similar in that they are both very unconventional, no-rules, practical self-defence, martial arts (although Krav isn't technically a martial art) which are no holds barred and generally formless. However... Krav Maga is basically a very raw, dangerous situation survival system (including avoidance and ...

There are non-Newtonian fluids that get harder when stressed (like cornflour and water), and there are others that get softer when stressed (like tomato ketchup, that acts solid until you apply stress by shaking it when it turns liquid and runny). There may be potential in filling a judo mat with the latter type of fluid, in that it will be a hard and solid ...

What is shown is a vambrace, or possibly a bracer repurposed to be more armor. A vambrace is a tube of armor, anything from metal to leather, used to protect the forearm. A bracer is intended only to protect the inside of the arm of an archer. What is shown in the image looks more like a bracer, but seems to be intended for use as armor, much like the ...

I train in Taekwondo and had a similar problem with my knees (though after a few years of training). At the time, my doctor diagnosed "chondromalacia patella", which he said was caused by an imbalance in strength of tendons/ligaments across the knee. He prescribed a set of exercises to help balance the strength. These exercises were quite simple and didn't ...

I would rate this a matter of personal choice. Getting hit in the groin is intensely painful, no matter what you have between your legs. Men have it a bit worse, due to the external bits having a better chance of actually getting badly damaged (and a burst testicle is no joke). On the flip side, cups are generally a bit awkward to wear, and can cause chafing ...

Those of you who aren't familiar with the concept of Non-Newtonian Fluids, the thing to realize is that they are fluid or solid depending on the stress exerted on them. If you fill a swimming pool with a non-Newtonian fluid, you'll be able to walk right across it. So long as you remain in motion, it will support your weight. As soon as you stop, however, you'...

For mat size, I am listing the official competition mat sizes as a reference to help you assess the difference between practicing throws and takedowns and practicing ground techniques: keep in mind that these are large competition areas meant to minimize out-of-bound stoppages and injury risks, and they are a reasonable upper bound for a mat used by two ...

How the heck can you walk in a ready stance down the street without the whole freaken place going 'ooooh, aaahhh'. I was trained in hand-to-hand combat by the IDF, not by a school or embassy, so my perspective may be different than that commonly taught. But I do use the same approach on my home street as I do in Jenin. There are two types of people who will ...

No they are not. The mouth guards are designed to protect against different kinds of impact most common to sports. You have the top only mouth guard which is meant to be something between your teeth for chomping impact. You have a separate top and bottom mouth guard which has a full set covering each teeth to help prevent outside impact into the teeth ...

When it comes to Taekwondo, as a female, wearing a groin protector is more annoying than being kicked in the private parts. The groin protector scrapes the sides of your legs and more often than not causes more damage from the impact than the kick itself would. Kicks hurt, that's normal. But being kicked in the privates as a female does not really add pain, ...

This is a cost analysis (kinda) answer1. What would being injured cost you? Do you have medical insurance/free health care? Would a broken hand/finger(s) mean you would be effectively unable to earn a living because you do a lot of manual work? Do you know how to use a left/right handed Dvorak keyboard? Once you have an idea of the cost of the injury as ...

Assuming that you cannot train yourself out of the Ridiculous Gag Reflex [patent pending]1, you could get a dentist to make your a custom made mouth guard. It might well be expensive but probably cheaper than having your teeth replaced. You may as well consider using sparing helmets as they might help. 1. I have no idea how you would even go about doing ...

I think a lot of people take Aikido out of context. Aikido is constantly belittled for the "here grab my wrist" thing, which is admittedly ubiquitous, but it is not the style to blame - it's the instruction. Similarly, the "compliance" thing is often tagged to Aikido too, and this is another area where there is nothing inherently defined in the style that ...

I have a little experience with these mats. Specifically, I've trained at places that use them. Here is what I can gather: Pros They are easily transportable They can be disassembled and reassembled very quickly Can be a great surface to practice kicking on because they provide a semi-soft landing Cons They aren't soft enough to safely practice falling on ...

Below is a link pertaining to a 3 month white belt who used Kotagaeshi to defend himself. It goes with the adage that self defence is 80% confidence. Basically a lot of things will work from a lot of martial arts, it's having the presence of mind at the time when your adrenaline is pumping that counts in that context. It has controls, pins and throws, ...

Am I allowed to use Krav Maga for any case of self-defense? Even a threatening or grave suspicion. You should never give this any concern in a real-life situation. You neutralize the attacker, and no more. If there are multiple attackers, you should be excessive on the first so that he will not return to the fight, but never do excessive harm to the last ...

In judo contests I have seen square steel tubing holding the mats together. Rigid, 5cm x 5cm steel tubes going around the tatami, tightened together by several tie-down-straps (ratchet strap is the correct name?) that go under the tatami. The whole package stays together just by gravity and the tension on the straps. The ratchets need to be covered though, ...

The weight of the glove is an indication of the amount of padding there to gradually decelerate your fist and transfer the impact energy gradually into whatever you hit. Extra padding takes longer to compress, and larger padding with more surface area spreads the impact to reduce the peak stresses and pressures. So, a heavier glove isn't more dangerous: ...

Like with all leather items, you just wash them by hand with dish soap and water. Don't immerse them in water, just use a washcloth. Then wipe them dry and hang them out to dry. If they're still stinky after that, you can try using a diluted solution of bleach (read the label on the bleach bottle to know how diluted). Apply the diluted bleach, leave for ...

I'm over 40 and train in taekwondo; I've never been advised not to do jumps or jumping kicks! I train with a gentleman who doesn't jump (for patterns or sparring), but he is nearly 80 and has arthritis! That's not to say my knees don't hurt at times. Some years ago, I had a problem with my knee called chondromalacia patella, which is caused by an imbalance ...

Judo has always used mats. In Judo Memoirs of Jigoro Kano, Kano (the founder of judo), measured practice spaces by the number of tatami mats. The warehouse afforded a practice area of only ten tamami mats, and there were square pillars here and there. The primary protection against injuries is technique and cooperation, not mats. The beginning lessons of ...

Costs for materials vary wildly from one place to another, as well as depending on the size you want, so I'll mostly give you options for construction and you can check on local availability and costs according to your personal requirements. Whatever you're going to be using, you'll need a flat base. A concrete slab would work, but so would a well crafted ...

Gloves protect your hands, not your head. It is actually safer to use lighter gloves, from the perspective of brain trauma. Research suggests greater brain trauma is suffered from boxers (8-14oz gloves) than MMA fighters (4oz gloves) because boxers take a high volume of shots, versus an MMA fighter that would have been knocked down or out, and finished from ...

Samurai is a rather large class ranging from foot solders to the Shogun. All wore different armours. Your question spans around a thousand years of history. So, generally speaking… A few armours have stiff joints. However, they are specific armours, for example tourney jousting ones. Those are donned for specific tasks and generally require staff to put on ...

Zebra mats has suggested layouts for 2m x 1m mats depending on the area you want to cover. It sounds like you are repeating layout A to cover your area. The problem with this is that when any mat is pushed (up, down, left, or right), only those mats directly in that line are affected. In layout B, for example, a push will be distributed among more mats. ...

Another thing you can do if you have a small mouth is to go the children/teen area of a large box sporting good store. They will have quite a few different sized mouthguards in various configurations for different aged athletes. As a personal recommendation, I really like the Shock Doctor brand mouthguards. They do have one model available in both youth and ...

Most of the techniques in aikido are based on creating an opening for you to manipulate/control your opponent through the use of leverage and/or pain. In order to do that you are going to have to get within arms reach of your opponent or literally toe to toe in some cases :). Aikido really shines when you can create that opening and use one of techniques ...
