What is standard deviation and CV? | Brian Serrano, DC, PhD, CCSP, ATC, RSCC, CPSS posted on the topic | LinkedIn (2025)

Sports Science x Sports 🏀 Performance This sheet is a result of two years of my work and even longer for both Geoff and Matt.Combing all of our knowledge of strength + conditioning and sport science, we used machine learning to narrow down 134 Kinexon variables into 10-15 of importance for various outcomes. Statistical Method: Unsupervised machine learning > Dimensionality Reduction > Principal Component Analysis This document is NOT meant to be a definite list of important variables. Rather, it should serve as a baseline and comparison for clinicians and practitioners within Basketball who use Kinexon in their current workflow.

Rehab x Sport Science My first PhD is in rehab science and I did this because that was my biggest weakness at the time, I was fascinated by wanting to learn how to take an athlete from injury back to their game. My second PhD is in sport science, because I wanted to learn how to use advanced statistics to add objectivity into the return to play model. Combing these two fields with this example using Kinexon data as the proxy. The goal is to hit 80% for today’s session before moving to full practice participation.

Real world math!When we think about the math used in sports, we often think about data collected and used for statistics. But this article shares how data is used to help improve athlete performance! 📈

Data Audits As sports scientists (actually any field within sports) should do a macro and micro audit after each season.As the regular season just ended, we are starting to interrogate many things, one of them being heart rate recovery ❤️🩹. One method of interrogation is looking at how recovery stacks up at home vs on the road.Some things to consider:1. External Validity 2. Internal Validity 3. Ecological Validity 4.

Readiness in Basketball 🏀 One challenge in professional basketball is obtaining consistent readiness data from players.If the modality of choice are force plates, then does the staff travel with them? Are they in the arena AND practice facility?If LPS tracking is the choice…is the staff tracking EVERY session (shootaround, game, etc.)My point is that as sports scientists we should be able to mix and match readiness data to overcome logistical challenges. One method I use are weighted, smoothing algorithms so running 1.5 miles can be compared to having an RR interval of 0.250 ms.Math x 🏀🏀 #athletictraining #athletictherapy #athleticperformance #athleticmedicine #strengthandconditioning #sportsperformance #sportsmedicine #sportschiropractic #basketball #basketballperformance #SportsScience

Understanding Estimation in Sports Science: The Kalman FilterHow do we accurately track an athlete's performance bounded by noisy data? The Kalman filter is a powerful tool in sports science for estimation.The Kalman filter minimizes error and maximizes precision by continuously updating estimates based on real-time data, ensuring athletes receive optimal training and performance insights.#SportsScience #KalmanFilter #PerformanceAnalysis #AthletePerformance #DataScience #TrainingOptimization #SportsTechnology #Sports

Do you use the French contrast method with your players?This method is proving to be increasingly popular due to the time efficient nature of the programme.The aim of French contrast training is to hit the various areas of the force-velocity curve in order to produce an acute adaptive response.Typically, this would follow the below sequence:1. Maximum force exercise2. Plyometric exercise3. Ballistic or speed-strength exercise4. Overspeed or assisted exerciseIn football, there is limited data showing the effectiveness of this method on physical measures.A recent study from Türkarslan (2024) showed significant improvements in vertical jump, 30m sprint, and dynamic balance values in professional senior players.Do you use the French contrast method and how do you like to programme it across the microcycle?Let me know in the comments below.

When it comes to tendon health monitoring and force plates, two variables that stand out to me are stiffness (indirect to the tendon) and peak power (how the system expresses itself. Using non-linear techniques to explore relationships between these two variables and potentially make programming for athletes.#athletictraining #athletictherapy #athleticperformance #athleticmedicine #strengthandconditioning #sportsperformance #sportsmedicine #sportschiropractic #basketball #basketballperformance #SportsScience
