Basketball - Stress Testing

"Hope is a good breakfast, but it is a bad supper." - Francis Bacon

Options and outcomes come with a variety of possibilities. "Stress testing" comes with different names and occurs in many fields to clarify "tolerances."

In basketball, hope gets you to tryouts. Stress testing decides who plays.

Stress Testing Examples

Stress testing reveals what holds and what doesn't under fatiguing conditions. 

In physiology, cardiopulmonary stress testing defines fitness (aerobic capacity), limiting factors (e.g. heart or lung), and may help define diseases (e.g. atherosclerotic heart disease, exercise-induced asthma). 

In engineering, testing turbines under conditions of temperature change (cold or heat) is called thermal stress testing. A metal could become unstable at varying temperatures and compromise engines. 

In banking, stress testing can project risk of bank failure under failing loan conditions and help set capital requirements.

Basketball Stress Testing

Stress testing occurs in different categories - physical, competitive, and cognitive loading. 

Strength, athleticism and conditioning are revealed in vertical jump, bench press, and running tests. The Celtics historically used "The Boston Marathon," full-court sprints over three minutes at the end of workouts to measure distance. They measure conditioning and resilience. 

Scrimmages assess basketball ability and IQ. Teams conduct them in a variety of setups including full-court and small sided games. 

Seeing "prospects" competing against established professionals or aspiring professionals (e.g. NBA Summer League) is another form of stress testing. 

Candidates undergo cognitive loading during film sessions as a proxy for basketball IQ. "Seeing earlier leads to deciding better." The more specificity players provide the better teams can assess them. 

High IQ players show certain traits:

• speak in principles, not guesses
• anticipate the next action (NBA = next best action)
• understand spacing, timing, and angles not just positioning
• admit mistakes 

Medical Evaluation

Medical evaluation will be limited at lower levels. Having a doctor's certification to play is usually enough. If the doctor suspects issues then players are triaged to specialists. 

In the NIL and Transfer Portal era, Medical Evaluation should be more extensive. Even the body gets stress tested, because availability is part of ability.

Everyone Performs Stress Testing

Everyone gets stress tested. How do we respond to  pressure? How do we prove ourselves?  Standardized testing in school is stress testing. 

SAT or ACT testing is a form of stress testing. "Fitting in" in many communities exerts a form of stress testing. In the 1970s we endured running testing in both high school and college sports. 

Testing doesn't create excellence. It reveals it. 

Lagniappe. "Coaching is a relationship business." 

The greatest compliment a coach can get isn't trophies or banners. 

It's when former players introduce you to their family and say,
This is Coach, the one who taught me how to be better on and off the court. That's the legacy that matters.
