Summary
Over half of Brazilian jiu-jitsu (BJJ) practitioners sustain injuries within six months. Injury risk is linked to training frequency and instructor status, with experience influencing injury location.
Area of Science:
- Sports Medicine
- Epidemiology
- Martial Arts Research
Background:
- Brazilian jiu-jitsu (BJJ) is a popular martial art with a growing participation base.
- Understanding injury patterns and risk factors is crucial for athlete safety and injury prevention in BJJ.
Purpose of the Study:
- To determine the 6-month incidence rate and anatomical pattern of BJJ-related injuries.
- To identify associations between BJJ injuries and practitioner experience, demographics, and training variables.
Main Methods:
- A descriptive epidemiology study utilizing an online survey.
- 1287 adult Brazilian jiu-jitsu practitioners participated.
- Data collected on 6-month injury incidence, injury location, and associated training/demographic factors.
Main Results:
- A 6-month injury incidence of 59.2% was reported, with the knee being the most common injury site.
- Increased training days per week and instructor status were associated with higher injury incidence.
- Higher body weight and more years of training were associated with lower injury incidence.
- Experienced practitioners reported more low back injuries, while novices sustained more upper extremity, head, and elbow injuries.
Conclusions:
- Injury risk factors in BJJ are identifiable and can inform targeted injury prevention strategies for instructors.
- The distinct injury patterns across experience levels highlight the need for tailored approaches by sports medicine professionals working with BJJ athletes.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

01:27Introduction to Surveying, Plane Surveying and Geodetic Surveys
1.0K
Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

01:27Types of Surveys

Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

01:28Survey Safety
374
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

01:19Errors and Mistakes in Surveying
642
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

Topographic surveying is critical for documenting the Earth's surface, focusing on capturing elevations, slopes, and natural and man-made features. It is essential in construction planning, water resource management, and land-use analysis. The primary outcome of such surveys is a topographic map, which uses contour lines to visually represent the shape and slope of the terrain, providing valuable insights into the landscape's characteristics.Contour lines are fundamental to understanding the...
