About this study
Official title: Designing and Evaluating a Smart Preventive Program for Injury Risk Prediction Associated With Environmental Factors Among Amateur Football Players in Jazan: A Controlled Study
This study evaluated a smart preventive program designed to predict injury risk associated with environmental factors among male amateur football players in Jazan, Saudi Arabia. The program considered environmental conditions, including temperature and humidity, as well as individual factors related to training readiness and preventive practices.
A total of 120 amateur football players were included in the study and divided into an intervention group and a control group, with 60 participants in each group. The intervention group used the smart preventive program, while the control group received no intervention from the study program.

The program aimed to help players recognize potentially unsafe training conditions and follow preventive recommendations related to training timing and intensity, hydration, rest breaks, warm-up, stretching, and sleep and recovery.
The study compared injury risk scores and preventive practices between the two groups. Injury occurrence was also assessed during the study period. The findings may help inform the development of practical, technology-based approaches to injury prevention among amateur football players training in hot environmental conditions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Smart Preventive ProgramBehavioural
A smart preventive program designed to assess injury risk associated with environmental conditions and individual readiness among amateur football players. The program provided risk classifications and preventive recommendations based on environmental factors, including temperature and humidity, as well as training-related factors such as warm-up, stretching, hydration, sleep, recovery, and perceived readiness. Recommendations were intended to help players adapt their training practices to reduce potential injury risk.
| Study group | Role | What they receive |
|---|---|---|
| Intervention Group | Experimental | Participants received the smart preventive program in addition to their regular football training. Receives: Behavioral: Smart Preventive Program |
| control group | No intervention | Participants continued their regular football training without using the smart preventive program. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Football-Related Injuries Recorded During the Study Period
Comparison of the number and proportion of participants experiencing football-related injuries between the intervention and control groups during the study period, based on injury data collected during the study.
Measured: 1 month
Secondary outcomes (3)
Environmental Risk Score Calculated Using the Aura Shield Program
Comparison of environmental risk scores between the intervention and control groups. The score is calculated using environmental data, including temperature and humidity, and daily questionnaire responses concerning behavioural and training-related factors, including sleep and playing surface conditions.
Measured: 1 month
Adherence to Preventive Behaviours Assessed Using the Aura Shield Daily Questionnaire
Comparison of adherence to warm-up, stretching, hydration, and recovery practices between the intervention and control groups, based on daily questionnaire responses collected during the study period.
Measured: 1 month
Injury Risk Classification Generated by the Aura Shield Program
Assessment of the program's ability to classify injury risk based on environmental data, including temperature and humidity, and behavioural and training-related factors collected through the daily questionnaire.
Measured: 1 month

Where is the study taking place?
The record lists 1 site in Saudi Arabia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Football-Related Injuries Recorded During the Study Period (time frame: 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07909681, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
