What does guard, sparring or kinetic chain mean? The Combat Sports ABC explains every key term casually and clearly – before you dive into our guides.
"What on earth is a guard, and why does everyone keep talking about the kinetic chain?" — honest answer: combat sports have their own language, and you're better off learning it before you get stuck halfway through your first guides. This glossary collects the terms that keep showing up across our combat sports guides — from judo to BJJ to Muay Thai — and explains them the way a training partner would on the mat, not a dictionary. Bookmark this page — you'll come back to it more often than you think.
Striking is the family of punching and kicking sports — boxing, kickboxing, Muay Thai, taekwondo, karate. It's about distance, timing, and reaction; you stay on your feet.
Grappling is the counterpart: throwing, clinching, ground control — judo, wrestling, BJJ. Instead of distance, body contact, balance, and leverage decide the fight.
Sparring is controlled practice fighting against a partner — the test run for your technique under real but dialed-back pressure. Not a competition, but shared learning with the handbrake on.
Kumite is the karate term for exactly this kind of partner training, from pre-arranged drills to free fighting. Randori (from judo/BJJ) is its counterpart: free but cooperative practice without full competitive intensity.
Gi (also judogi, karategi — German: "Gi") is the heavy-cloth training uniform in traditional combat sports — it gives you grips for throwing and controlling that regular sportswear simply doesn't offer.
Rashguard is the tight-fitting technical shirt for no-gi training (BJJ, MMA) — it protects your skin from friction and lowers the risk of skin infections during close ground contact.
Hand wraps (German: "Bandagen") go around your hand and wrist before striking training — they stabilize the joint and spread out impact so your wrist doesn't buckle on a hard hit.
Mouthguard (German: "Mundschutz") is the cheapest insurance against dental and jaw injuries once contact enters the picture. A boil-and-bite model you mold yourself at home in hot water — noticeably better than the loose off-the-shelf version.
Headgear (German: "Kopfschutz") and a groin guard (German: "Tiefschutz") pad your head and lower body during sparring. Important to know: headgear prevents cuts and split skin, but not concussions — for that, only how hard your partner hits actually matters.
Shin guards (German: "Schienbeinschoner") protect your shins in kicking disciplines like Muay Thai or kickboxing from bruising during sparring and bag work.
Belt (German: "Gürtel", belt system: "Gürtelsystem") is the color-coded rank that makes your progress visible — from white to black, with wildly different time-per-rank depending on the sport.
Fighting stance (German: "Auslage") is your base stance in striking: feet staggered, hands up, ready to hit and to defend. Your personal starting position for every movement.
Cover (defensive posture, German: "Deckung" — not to be confused with the grappling "guard" below) is the position that shields your head and torso from strikes — hands up, chin down, like a shield you carry with you.
Base leg (German: "Standbein") is the leg you stand on while kicking with the other — and it's actually this leg that generates most of the power, not the kicking leg itself.
Footwork (German: "Beinarbeit") is the art of moving without losing your balance or your distance control — the invisible part that decides whether a strike lands or not.
Kinetic chain (German: "kinetische Kette") describes how power travels through your body like a whip: big and slow at the hip, small and fast at the fist or foot. The order is proximal (close to the body, moves first — hip, torso) before distal (far from the body, moves last — hand, foot).
Guard is a ground position where you control your opponent with your legs while lying underneath them — in BJJ, often one of the strongest positions, not the weakest.
Takedown is any technique that brings your opponent from standing to the mat — from a clean judo throw to a wrestling double-leg.
Sprawl is your defense against exactly that: you throw your hips back and your legs down so nobody can drag you to the ground.
Clinch is standing close-range combat — you hold onto your opponent, usually around the head or upper body, to control distance and balance.
Submission is a joint lock or choke that forces your opponent to give up. Tap (German: "Tap" / "abklopfen") is the signal for it — the single most important rule in grappling: tap early rather than get hurt late.
Ukemi is the Japanese art of falling safely — how you land after a throw without hurting yourself. It's the very first thing you learn in judo, before you ever get thrown.
Teep is the push kick in Muay Thai — not a damage strike but a range weapon that keeps your opponent at arm's length, foot instead of hand.
Roundhouse kick is the classic circular kick with the shin or foot, where the hip rotates all the way through — one of the most powerful techniques in combat sports.
Kime is the karate term for focused, fraction-of-a-second power delivery at the exact moment of impact — the difference between a strike that touches and one that actually lands.
Kata is a choreographed movement sequence in karate — solo "shadowboxing" against imaginary opponents that trains technique, balance, and timing all at once.
Ippon is the full point in judo competition — a clean throw or successful ground control that ends the match instantly. Waza-ari is the half-point below it; two of them also add up to a win.
Weight cutting (German: "Gewichtmachen") is deliberate, often extreme dieting before weigh-in for competition — a pro-level topic that has no place in recreational training.
If you run into a term in a guide that you don't know, don't skim past it — jump back here for a second. Most combat sports confusion doesn't come from bad technique, it comes from beginners misunderstanding a word and then practicing it wrong. Five minutes of vocabulary saves you weeks of confusion on the mat.
Striking covers punching and kicking sports at range (boxing, Muay Thai, karate), where you stay on your feet. Grappling is about throwing, clinching, and ground control (judo, wrestling, BJJ), where body contact and leverage decide things. Many athletes train both — in MMA, the two families merge completely.
Sparring is controlled practice fighting against a real partner, where you test your technique under real but dialed-back pressure. It isn't a competition: the goal is shared learning at an agreed intensity, not winning at any cost. Good gyms clearly agree on intensity before every round.
The kinetic chain is the order in which power moves through your body — like a whip that starts big at the hip and ends small and fast at the hand or foot. If your end segment moves first instead of last, your power dissipates no matter how strong you are.
Guard is a ground position from grappling where you control a kneeling or standing opponent using your legs while lying underneath them. In BJJ it's often one of the strongest positions in the sport, letting you attack and defend at the same time.
Tapping (tap out) is the submission signal for a joint lock or choke — you strike your partner, the mat, or yourself repeatedly, and your opponent releases immediately. It's not a sign of weakness, it's the most important safety rule in grappling: tap early and often rather than risk an injury.
