BUTTON UP!

In 10m and 3-Position precision air rifle shooting, the stiff canvas and leather shooting jacket is a critical piece of equipment designed to create a stable, skeletal support system.

Leaving the second button from the botto unbuttoned drastically alters the biomechanics and structural integrity of the standing position.
Based on the technical analysis shown in the drawing, here are the direct consequences:

1. Collapse of the "Oberkörper-Rotations-Limit" (Torso Rotation Limit)
The drawing highlights the *Oberkörper-Rotations-Limit*, which is the jacket’s ability to lock the upper body and spine into a rigid, repeatable structure.
The Consequence: Unbuttoning this specific button allows the lower half of the jacket to flare open. This breaks the rigid cylinder around your core, introducing unwanted axial rotation (twisting) and lateral sway in the torso.

2. Shift in the Center of Gravity and Balance Vectors
The diagram illustrates *Balance-Vektoren* radiating from the base and tripod stand, mapping out the *Optimale Haltungsgeometrie* (Optimal Posture Geometry).
The Consequence:
In a correct standing position, the hips are often pushed forward slightly to rest the support elbow firmly on the hip bone or iliac crest. The lower buttons of the jacket hold this hip-and-lower-back bridge together. Without that specific button fastened, the jacket cannot support the weight of the rifle distributed through the elbow. The shooter will have to engage active muscle tension in the lower back and core to compensate, causing the balance vectors to fluctuate and increasing body sway.

3. Disruption of the Sight Cone Precision (*Sichtkabel-Präzision*)
The graphic shows an incredibly tight tolerance for head positioning and sight alignment (+/- 0.01^{\circ}).
The Consequence: Because the lower spine and pelvis lose their rigid support system, micro-movements will travel all the way up to the shoulders and neck. This makes it incredibly difficult to maintain a consistent cheek weld on the cheekpiece. If your head shifts even a millimeter due to a loose lower jacket, your eye alignment through the diopter changes, destroying your consistency.

4. Foot Placement and Stability Breakdown (*Fuß-Platzierungs-Zone*)
The drawing displays concentric stability rings around the feet with a tiny +/- 1\text{mm} tolerance.
The Consequence: When the jacket is fully buttoned, it helps channel the weight of the rifle and upper body straight down through the skeleton into the *Optimale Haltungsgeometrie*. When the lower jacket is loose, the upper body hunts for stability, causing weight to shift dynamically between the heels and toes. You will see the pressure distribution in the shooting shoes fluctuate outside that ideal 1\text{mm} zone.

ISSF / Rules Note: Beyond the biomechanical disadvantages, leaving a button undone to gain flexibility or alter how the jacket sits on the hips can easily cross into an equipment control violation. The jacket is inspected and stiffness-tested under the assumption that it functions as a single, fully closed support unit.

In short, unbuttoning that second button trades **passive skeletal stability** for **active muscular strain**, directly widening your hold area and dropping your scores.

Why does an athlete when performing mediocre at a championship boast that it is because he did not practice?

It is a psychological defense mechanism known as self-handicapping.

When an athlete claims they didn't practice after a mediocre or poor performance, they are unconsciously (and sometimes consciously) trying to protect their ego and control how other people view their talent.

Here is a breakdown of why athletes do this and how it functions as a psychological safety net:

1. Saving Face (The Ego Shield)
If an athlete trains intensely, gives 100%, and still performs poorly, it implies a painful truth: their best wasn't good enough, or they lack the talent. By claiming they didn't practice, they change the narrative. The mediocre score is no longer a reflection of their ultimate ability; it’s just a reflection of their lack of preparation.

2. The "Win-Win" Illusion
Self-handicapping creates a scenario where the athlete feels they can't truly "lose" in the eyes of others:

If they perform badly: "Well, of course, I haven't picked up the gear in weeks." (The lack of practice excuses the failure).
If they somehow perform brilliantly: "Wow, I didn't even practice and I still pulled that off!" (This makes them look like an absolute natural genius).
3. Controlling the Narrative
In competitive environments, athletes tie a massive part of their identity to their performance. Admitting a lack of preparation is a way to maintain status. It signals to coaches, teammates, and competitors: "I am still a threat; I just didn't try this time."

The Growth Mindset Trap: While self-handicapping protects the ego in the short term, it creates a toxic cycle. True progress requires a growth mindset, where failure is seen as a data point for improvement, not a definition of one's worth.

Coaches and sports psychologists often try to break this habit by shifting the focus away from "natural talent" and heavily rewarding effort, consistency, and accountability instead.
