In actual combat or sports competitions, short-term improvement of combat advantage requires a combination of tactical strategy, physical state and psychological quality optimization. The following are recommendations based on legality and technicality (please note: all actions must comply with laws and regulations and are only used for self-defense or arena scenes)： 1. Tactical-level skills (effective immediately) 1. Space control skills • Seize the axis of attack: place yourself on the opponent's flank or visual blind spot through foot movement, forcing the opponent to adjust their posture and consume physical energy. •Create angle difference: cut in at 45 degrees to shorten the attack distance, while expanding the depth of your own defense (such as angle jabs in boxing) 2. Neural response optimization • Prediction point locking: Focus on observing the micro-movements of the opponent's clavicle/hip joint, which is 0.3 seconds faster than tracking the movements of the limbs to predict the attack trajectory * Auditory assistance: judge the timing of the opponent's force through the rhythm of breathing, and launch a counterattack during the neural refractory period of 0.2 seconds at the end of exhalation• 2. Biomechanical optimization (10 minutes preparation) 1. Dynamic chain activation • Perform 3 sets of 30-second diagonal stretching of the elastic band (thoracic spine-contralateral hip joint) to increase the explosive power of rotation by 15-20% • Rapid centrifugal training: 2 minutes weight squat (squat for 3 seconds, stand up for 0.5 seconds) to activate type II muscle fibers 2. Neuromuscular arousal *Cold stimulation method: Quickly wipe the ulnar nerve area of the forearm (little finger side) with an ice pack for 10 seconds to increase the reaction speed of the hand • Vestibular stimulation: close your eyes and turn one leg in place for 3 laps and immediately open your eyes, short-term improvement of homeostasis ability 40% 3. Psychological tactics module (effective in 5 seconds) 1. Perceptual interference •Line of sight guidance: Suddenly look at the opponent's right shoulder 0.5 seconds before the attack, and actually attack the left abdomen (humans have 0.25 seconds of visual inertia) •Diversion: Use short tooth erasure (tsst) to trigger the opponent's blink reflex (average duration 100-150ms) 2. Pressure multiplier strategy *Rhythm destruction: Use asymmetric attack intervals (such as 0.8 seconds-1.3 seconds-0.6 seconds) to disrupt the opponent's prediction mode • Breathing synchronization: Establish a subconscious connection by imitating the opponent's breathing rate, and mutate the rhythm to launch an attack during the third exhalation. 4. Emergency agreement (only for self-defense) 1. Ergonomic weaknesses * Priority attack on power chain nodes: subclavian muscles (affecting upper limb strength), gastrocnemius muscle-flounder muscle connection (destroying pedaling force) •Environmental mechanics: Use the wall to achieve 2.7 times the force magnification (back against the wall when elbowing can increase the impact force) 2. Emergency equipment conversion • Weaponization of daily objects: the pen implements anti-grip thrusts (aiming at the rib angle of 30 degrees to cut in), and the belt is used as a torque amplifier (extend the attack radius during thrusts). Important note： 1. All technologies shall comply with the limits of self-defense stipulated by law 2. Systematic training is required to improve the real combat effectiveness, and the above techniques only provide temporary marginal advantages. 3. It is recommended to carry out adaptive training under professional guidance to avoid accidental injuries 4. Priority is given to the exit strategy, and force should be the last choice (Note: The technical parameters described in this article are based on the study of exercise biomechanics, and there are individual differences in actual effects)
