What is the primary purpose of performing a break-fall (ukemi) in judo self-defense?
To maintain a higher center of gravity
To increase the speed of the throw
To intimidate an opponent with a loud slap
To reduce injury by safely absorbing the impact of a fall
Ukemi techniques teach practitioners how to land safely and dissipate force, minimizing the risk of injury. Proper break-falling absorbs impact through rolling and slapping movements.
Which defensive stance in judo is best for improving reaction time and mobility?
Standing upright with legs fully extended
Legs wide with knees locked
Feet shoulder-width apart with knees slightly bent and weight centered
Leaning back on one heel with front leg straight
A balanced stance with bent knees lowers the center of gravity and allows quick movements. Centered weight distribution enhances stability and reaction speed.
Which of the following is a basic judo hip throw commonly used in self-defense?
Uchi-mata
Osoto-gari
Seoi-nage
O-goshi
O-goshi is a fundamental hip throw where the defender turns and lifts the opponent over the hip. It is simple and effective for controlling balance.
In grip-fighting strategies, what is the standard grip combination used to control an opponent safely?
Both hands on the opponent's belt
Cross-gripping both collars
One hand on the lapel and one hand on the sleeve
Double overhooks on the arms
The classic lapel-and-sleeve grip provides control over the opponent's upper body while leaving room to execute throws. It also maintains a flexible connection for kuzushi.
Which judo joint-lock technique specifically applies pressure to the opponent's elbow joint?
Kote-gaeshi
Waki-gatame
Ude-hishigi-hiza-gatame
Juji-gatame
Juji-gatame, or the cross arm lock, hyperextends the elbow by securing the arm between the legs. It is a fundamental submission in self-defense.
What is kuzushi in judo and why is it essential for effective throws?
The act of breaking an opponent's balance to set up a throw
A pinning hold on the ground
A foot sweep targeting the ankle
A defensive posture with low stance
Kuzushi involves disrupting an opponent's stability to make throws easier to execute. Without balance-breaking, most throwing techniques are ineffective.
Which hold-down technique involves controlling the opponent's head and arm across the chest?
Kesa-gatame
Kami-shiho-gatame
Tate-shiho-gatame
Yoko-shiho-gatame
In kesa-gatame, the defender pins the opponent by wrapping an arm around the head and controlling the near arm, keeping weight distributed across the chest. This hold-down prevents bridging escapes.
Which ukemi technique is used when falling backward?
Zenpo kaiten
Mae-ukemi
Ushiro-ukemi
Yoko-ukemi
Ushiro-ukemi is the backward break-fall that cushions impact by slapping the mat and tucking the chin. It prevents head and spinal injuries during backward falls.
What is the primary objective of grip-fighting in judo self-defense?
To maintain maximum distance without engagement
To immobilize the opponent's legs immediately
To secure a dominant grip that facilitates throws
To tire the opponent with repetitive grabs
Effective grip-fighting aims to gain the optimal hand placement to control posture and off-balance the opponent. Dominant grips open opportunities for techniques.
Ude-garami is a joint-lock targeting which joint in self-defense applications?
Elbow
Knee
Shoulder
Wrist
Ude-garami, or the entangled arm lock, applies rotational pressure to the shoulder joint. It can be used in self-defense to control or submit an attacker.
How is uchi-mata classified in judo throwing techniques?
Hold-down
Arm lock
Foot sweep
Inner thigh sweep throw
Uchi-mata is executed by lifting the opponent with the thigh and sweeping their inner thigh. It falls under nage-waza as a major hip throw variation.
Which judo principle is translated as 'maximum efficiency, minimum effort'?
Kuzushi
Jita kyoei
Seiryoku zenyo
Ukemi
Seiryoku zenyo focuses on using skill and timing to achieve maximum effect with minimal force. It underpins efficient technique in both throws and self-defense.
Which ukemi technique is performed when falling to the side?
Ushiro-ukemi
Mae-ukemi
Ko-ukemi
Yoko-ukemi
Yoko-ukemi is the side break-fall that disperses impact by rolling onto the shoulder. It is essential for safely absorbing lateral throws.
In self-defense, what is the ideal distance to maintain from an opponent to strike effectively?
Approximately one arm's length
Just outside the opponent's reach
Close chest to chest
At kicking distance only
Maintaining one arm's length allows for effective punches, throws, and disengagement. Too close or too far compromises reaction time and control.
During grip-fighting, which technique is used to break an opponent's sleeve grip?
Twisting the entire body away
Using a headlock to distract
Stepping backward sharply
Pinching the fabric between the thumb and fingers
Pinching the opponent's sleeve material near the cuff and pulling breaks their grip by collapsing the fabric. This tactical move opens space for attack.
An opponent grabs your lapel with one hand. Which sequence best counters this grip before executing a throw?
Pull directly back on the lapel and step in for O-goshi
Duck under the grip and apply Kote-gaeshi immediately
Ignore the lapel grip and attack with a leg sweep
Use the free hand to break the lapel grip, secure a sleeve grip, then execute seoi-nage
Breaking the lapel grip prevents the opponent from controlling your posture. Securing a sleeve grip and applying seoi-nage uses kuzushi effectively after neutralizing their hold.
Which throwing technique is most effective in confined spaces where hip rotation is limited?
Harai-goshi
Tomoe-nage
De-ashi-barai (advanced foot sweep)
Uchi-mata
De-ashi-barai requires minimal body rotation and uses timing to sweep the opponent's foot. It is well-suited for tight quarters where large hip movements are restricted.
When applying a joint lock in an emergency self-defense scenario, which consideration is most critical?
Apply pressure gradually to monitor the pain threshold and avoid permanent damage
Maximize force instantly to ensure compliance
Use joint locks only after immobilizing with strikes
Release immediately after pain is felt to avoid escalation
Gradual application of pressure allows control over the joint without causing unnecessary injury. This cautious approach balances stopping aggression with legal and ethical considerations.
Which hold-down technique provides the strongest control when the opponent attempts to bridge and roll?
Tate-shiho-gatame
Kesa-gatame
Yoko-shiho-gatame
Kami-shiho-gatame
Yoko-shiho-gatame secures the opponent's legs and torso from the side, limiting their ability to bridge effectively. It distributes weight to counter strong escapes.
What does tai-sabaki refer to in judo self-defense, and why is it important?
A ground hold to immobilize the opponent
A high-speed break-fall technique
Pivoting body movement to avoid attack and create a throwing angle
A double sleeve grip to control distance
Tai-sabaki involves shifting the body off the line of attack to avoid strikes and position for techniques. It is crucial for creating angles and maintaining control in self-defense.
