Question 1

What is thermal imaging/thermography?

Accepted Answer

Thermography is the process of detecting infrared (IR) energy emitted from a surface using thermal cameras and converting that energy into a temperature map. In the human body, different temperature regions often indicate conditions such as circulatory disorders, inflammation, fatigue, or injury. In athlete health and performance analysis, this technology is a highly effective tool for detecting abnormalities in muscle groups.

Question 2

Can thermography be used for athlete injury and risk analysis?

Accepted Answer

Yes, thermography is an effective method for injury and fatigue risk analysis in athletes. Thermal images detect temperature changes in muscle groups, indicating potential injury risks or signs of overuse. The aivisiontech ai4sports software analyzes this data to quickly and accurately evaluate whether there is a risk of fatigue or injury across 40 distinct muscle groups. This enables preventive interventions and performance improvement.

Question 3

How should thermal imaging be performed?

Accepted Answer

To obtain accurate results in thermal imaging, there are rules to follow under three main headings:
Athlete Preparation
Before imaging, the athlete should wait 15–30 minutes in a thermally neutral room (20–23°C) to stabilize body temperature.To prevent thermal reflections, the imaging area should be free from clothing and accessories (e.g., jewelry).Do not apply cosmetics, creams, or any other substances to the skin to be imaged.Avoid hot/cold compression and baths, sauna, steam rooms, etc., before imaging.Avoid coffee/alcohol consumption before imaging.
Imaging Conditions
Ambient Temperature: 20–23°C (stable).Humidity: Between 30%–60%.There should be no airflow or direct sunlight.In the background, there should be no reflective surfaces (mirror, tile, etc.) or heat sources (radiator, AC, etc.).The athlete should stand on a step board.
Camera Settings
The thermal camera should be calibrated according to ambient conditions. Most thermal cameras auto-calibrate.The shooting angle is generally set perpendicular to the body region.The camera emissivity value should be 0.98.The color palette should be 'Rainbow'.

Question 7

In which sports can ai4sports be used?

Accepted Answer

ai4sports can be used by athletes and clubs across all sports.

Question 8

How does ai4sports analyze injury/fatigue?

Accepted Answer

ai4sports AI software analyzes relevant muscle regions and their associated temperature values from thermal images. The average temperature differences between symmetric muscle regions are used as an indicator of injury risk. As the temperature difference increases, the risk of injury rises proportionally.
Fatigue analysis is performed by evaluating inflammatory regions detected within the muscles. The AI calculates the size of these inflammatory areas and their counterparts in symmetrical muscle regions. An increase in inflammation differences indicates that a particular region is under greater load or that physiological activity is more intense in that region. These findings are used to understand the athlete's fatigue level and are referred to as the "fatigue assessment".

Question 9

How often should thermal imaging/analysis be performed?

Accepted Answer

For thermal analysis, it is recommended to capture images before and after every training session. However, for teams that cannot perform imaging regularly, the ideal frequency is determined based on match day (MD). Accordingly, imaging is recommended on MD+24, MD+48, MD-48, and MD-24. This ensures regular monitoring of processes that may affect the athlete's condition.

Question 10

How can I view my thermal analyses?

Accepted Answer

Thermal analysis reports for athletes are saved in their individual profiles. To view thermal analysis reports, go to the relevant athlete's profile. You can also review recent reports on the home page to view analyses for a selected date or for a specific athlete together, and examine any report in detail.

Question 11

Which muscles can be analyzed?

Accepted Answer

ai4sports AI software can analyze a total of 40 muscle groups: 18 in the lower extremities and 22 in the upper extremities. Since thermal imaging measures infrared energy reflected from the surface, the muscles that can be analyzed are generally those closer to the surface.
Lower Extremity Muscle Groups

This comprehensive muscle analysis provides detailed data for performance evaluation, identification of injury risks, and fatigue monitoring.

Question 12

How should injury and fatigue analyses be interpreted?

Accepted Answer

Injury Analysis
Injury analysis is performed by evaluating thermal asymmetries in symmetrical muscle regions. As thermal asymmetries increase, the severity of injury risk also increases. This risk assessment should be interpreted by club healthcare professionals, taking into account the athlete's current or past injuries. Personalizing training programs and treatment protocols is important to protect the identified risk areas.
Fatigue Analysis
Fatigue assessment is carried out by comparing inflammatory regions in symmetrical muscle areas. An increase in inflammatory regions indicates overuse or potential damage to the muscles.
Pre-Training Fatigue:
Signs of fatigue before training indicate that the athlete has not rested sufficiently. In this case, personalizing training programs and protecting at-risk muscle regions is recommended.
Post-Training Fatigue:
Fatigue observed after training is associated with overuse of muscles. If overuse is not properly assessed, it can lead to injuries. Therefore, it is critical to plan rest and treatment processes according to the athlete's fatigue level.
Both analyses should be monitored regularly to prevent injuries and ensure sustainable performance.

Question 13

What is Before/After analysis?

Accepted Answer

Before/After analysis is the comparison of thermal evaluations performed before and after training. In this analysis, each muscle region is compared not with its symmetrical counterpart, but with its own prior state. Thus, each muscle's response to training is evaluated objectively. This method provides a clearer demonstration of the effects of training on the muscles.

Question 14

What are daily and periodic evaluations?

Accepted Answer

Daily Evaluation
Daily evaluation enables a collective review of the team's thermal analyses for a specific day. During this evaluation, data can be filtered using criteria such as analysis type, player positions, injury/fatigue assessment, and capture time. This allows for a detailed analysis of the team's daily performance and condition.
Periodic Evaluation
Periodic evaluation offers the opportunity to collectively review all thermal analyses of athletes within a selected date range. As with daily evaluation, analyses can be filtered by player positions, analysis type, injury/fatigue status, and other determined criteria. This method provides a comprehensive perspective for long-term analyses and process tracking.

Question 15

What are PMCS and PMSS scores?

Accepted Answer

PMCS, PMTS, and PMSS are models used to predict athletes' injury and fatigue risks.
PMCS stands for Periodic Muscle Condition Score, PMTS stands for Periodic Muscle Tiredness Score, while PMSS stands for Periodic Muscle Status Score.
PMCS
PMCS is calculated using injury grading data from the last five reports, with greater weight given to recent data.
PMCS -> The weighted average of the total injury grades from the last five reports, where more recent reports are emphasized.
PMTS
PMTS is calculated using fatigue grading data from the last five reports, with greater weight given to recent data.
PMTS -> The weighted average of the total fatigue grades from the last five reports, where more recent reports are emphasized.
PMSS
PMSS is used to detect a sudden increase or decrease in muscle condition. It evaluates the average temperatures from the last five reports and compares them with the most recent report.
PMSS -> The z-score of the average temperatures from the last five reports is calculated and then compared with the average temperature in the latest report to identify any changes.

Question 16

How is posture analysis performed?

Accepted Answer

Posture analysis is carried out in an integrated manner with full-body thermal imaging. During the analysis, the spatial orientation regions and angles of specific reference points (ear, shoulder, pelvis, knee, and ankle) on the athlete's right and left sides are calculated.
Thermal evaluation provides a unique contribution to posture analysis. The thermal distribution in the body offers critical information for detecting asymmetries or compensation mechanisms in the musculoskeletal system. For example, thermal abnormalities may indicate uneven muscle loading, inflammation, or injury risks. Combining these data with posture analysis makes it possible to perform a more comprehensive and objective evaluation of the athlete's body mechanics, balance, and performance.
This integrated approach provides effective guidance both in developing injury prevention strategies and in rehabilitation processes.
