RETURN-TO-PLAY – NFL HAMSTRING INJURIES
DESCRIPTION
There are an average of 176 hamstring injuries each season in the NFL. Once a player sustains an injury, they are more prone to re injuring the same muscle. Players with hamstring injuries miss an average of 13 days depending on the severity.
While practicing return-to-play protocol for hamstring injuries, one NFL team used STRIVE. Taking into account body composition, position, left vs. right dominance and previous injuries, STRIVE discovered how certain exercises affect specific muscle groups differently on individual players.
RESULTS
With this finding, the team worked collaboratively with strength coaches, athletic trainers and physical therapists to ensure they were prescribing the right treatments and workouts for individual athletes. The ability to monitor the real-time muscle activity allowed coaches to verify the athletes were working the right muscle groups and not compensating with others.
This, combined with the ability to monitor the athletes for muscle symmetry across both workouts and practice, provided insights to ensure the player returned to 100% before practicing or playing.
TEAM’S RETURN-TO-PLAY PROTOCOL WORKOUT
DISCUSSION
STRIVE is a valuable tool in detecting recovery stages of hamstring injuries. By bringing the athlete’s hamstrings back to 70% of capable activity, the player was ready to resume regular exercises at a controlled base. This was critical for the team to ensure that both force and contractions were at normal levels before the player resumed daily loads. This resulted in a step-by-step increase in activity, resulting in safe and effective return to play.

NCAA WOMEN’S BASKETBALL TEAM TRACKS SPRINTS USING STRIVE TECH
PURPOSE
Understanding game workloads allow coaches better insight into the demands of Women’s Basketball at the NCAA D1 Level. Coaches look to prescribe training loads in the gym and on the court through progressions that appropriately prepare athletes to perform during matches. Most team sport that require demands of intermittent exercise include the ability to perform through high-intensity bouts of high-speed running. The purpose of this case study was to capture, analyze and visually prepare data to better understand sprinting demands of Division 1 Collegiate Women’s Basketball.
BACKGROUND
Strive is a performance tracking wearable technology system seamlessly integrated into compression shorts for both female and male athletes utilize in all training settings. The garments are comfortable, can be embedded in whatever brand the team desires, and…
ASSOCIATION BETWEEN FATIGUE AND GAME PERFORMANCE
DESCRIPTION
Tracking metrics like speed, distance and accelerations can reveal patterns in practices and games that allow coaching staff to make adjustments. In addition to those metrics, one team wanted to understand the amount of effort players exerted throughout a week leading up to a game. The team employed STRIVE to track both the external metrics as well as the muscle EMG activity.
RESULTS
STRIVE worked with the team to analyze the results and found an interesting early correlation: The overall fatigue of the team, which compared how hard the muscles worked to produce the accelerations, directly correlated with the how well the team performed in the game. Essentially, the team performed below their potential when the players approached fatigue the week leading up to a game.
MONITORING INTENSITY OF GAME VS. PRACTICE
DESCRIPTION
How can coaches structure their weekly practices to better prepare for a game? One team wanted to replicate drills that produced similar game-time intensity that would allow them to structure their practices to optimize performance. With the help of STRIVE, they collected millions of data points across jumps, distance and accelerations to see what insights they could capture before games.
RESULTS
By analyzing the practices and non-conference games at the start of the season, the team identified how the opponent’s style of play impacted their player’s metrics. Using this information, the team made adjustments to their weekly practice schedule in an effort to get the same results in practice as on game day.
CHANGES IN PLAYER LOAD? SYSTEMS INTERROGATION
ABSTRACT
The purpose of this paper is to evaluate the use and utility of Sense3, a sensor system embedded in compression shorts that measure kinematic changes, muscle activation and physiology in elite athletes.
THE PROBLEM
Elite sports teams have been monitoring athlete loads through wearable technology for close to 10 years, yet most leagues and teams have yet to see a quantifiable reduction in athlete injury or a significant change in performance-based outputs. In many cases, the technologies provide a singular load metric “score” indicating a difference from game to game- or practice sessions. Practitioners are left to make “inferences” on why the score changed, without forming a direct rationale as to which biological system…
RETURN-TO-PLAY – INTERNAL VS EXTERNAL LOAD
DESCRIPTION
As the player started return-to-play protocol, the team asked STRIVE to re-assess his efficiency. The goal was to replicate the pre-injury practice session and identify any significant changes that could impact his recovery.
RESULTS
Before the injury, the player was found very efficient likely due to his conditioning to recovery balance. When STRIVE re-assessed the player post-injury, it showed that the internal load drastically increased even though the external load stayed consistent causing his efficiency to decrease nearly 40%.

STRIVE'S CAPTURES REPETITIONS OF 400 METERS, ALL APPROXIMATELY 90 SECONDS
INTRODUCTION
Currently, athletic organizations relate “Player Load” as a metric of output. IMU tech measures the output of an athlete’s session and then a load is provided for use in comparison with the athlete’s body of data to detect longitudinal trends and outliers. This number is then used as insight into how hard a session was for an athlete in relation to all other sessions, and sometimes even used as an injury risk indicator. In reality, the term Player Load is much broader than a simple movement score provided by an accelerometer. The amount of stress that an athlete’s body is under, influences the difficulty of a session. A movement score is not without value, and it plays an important role in the idea of a player’s load. However, there is additional context that is needed to fill out the picture that is true Player Load.
ANALYZING INTERNAL & EXTERNAL LOAD IN DIVISION I NCAA BASKETBALL TEAM
DESCRIPTION
Electromyography (EMG) is a diagnostic technique that evaluates and measures the electrical activity of skeletal muscles. The resultant amplitude of the muscles can help provide an approximation of internal load or how much work the muscles have done during an exercise period. With the noticeable uptick in the usage of wearable technology that measures external load, most strength and conditioning practitioners, athletic trainers, and other athletic organizational professionals are aware of the usefulness of an external load measurement. While the external load metric is useful in approximating the output of an athlete within an exercise session there is no accounting for the workload felt internally, by the muscles. One popular purpose of measuring external load is to reduce general fatigue and chronic stress. This is a reasonable…
INTRODUCTION
Periodization in sport is important. Seasons can be long and grueling, and an organization always needs to be aware of the fatigue status of its athletes. With the influx of wearable tech, the increasingly common way to monitor load status in athletes is to obtain an external load metric (traditional player load) and monitor it over the course of a season. This has worked well for visualizing periodization of athlete training. With an external workload quantified, teams now have a better idea of what a “normal” external workload is at an individual athlete level or a more general team level. This is a good start but is missing a key piece of information. When measuring external load…
INTRODUCTION
Fatigue is the key driver in exposing weaknesses and deficiencies in athletes’ performance. Traditional methods have been inadequate in location weakness points and ensuing compensation when athletes enter fatigue stages. To mitigate further injuries, coaches have been working with players strengthening their muscles in symmetric ways, whether left to right, or posterior and anterior. To understand this better, we will look at the athlete who conducted six extensive drills as a part of a daily workout. In this example, we will discuss how fatigue affects this athlete and his muscle response during the compensation.
