Summary:
The objectives of the study are to evaluate core stability and static and dynamic balance performance in adult female hip-hop dancers and compare these scores with those of healthy non-dancer females; to obtain the injury history of dancers in the last year; to follow the occurrence of new injuries for three months; and to examine the relationship between these physical performance scores and injuries.

At baseline, the hip-hop group and the non-dancer group will undergo physical performance tests.

At baseline, the hip-hop group will complete a survey asking about injury history in the past year, then complete an online survey each week for three months for injury surveillance.

Primary Outcome Measures: Total Number of Musculoskeletal Injuries, The term "injury" refers to anatomic tissue-level impairment as diagnosed by a physician that results in full time loss from activity for one or more days beyond the day of onset. "Activity" in this definition means participation in a class, rehearsal, or performance., Upon completion of the three-month injury surveillance|Core Endurance Performance, The maximum amount of time spent maintaining the correct position in each of the flexor, extensor, and bilateral side bridge tests. The time will be recorded in seconds., At baseline|Balance Performance, For the assessment of static balance, the maximum amount of time and mean time spent maintaining the correct position in the unipedal stance test (performed both with eyes open and with eyes closed for both legs). The time will be recorded in seconds. Each trial will last a maximum of 45 seconds.

For the assessment of dynamic balance, the maximum reach distance and normalized reach distance (reach divided by leg length × 100) for three directions (anterior, posterolateral, and posteromedial) in the modified star excursion balance test (for both legs). Reach distance and leg length will be measured in centimeters., At baseline
Secondary Outcome Measures: Injury Occurrence Rate, Each participation in a class, rehearsal, or performance in which the dancer was exposed to the possibility of a dance injury constitutes one exposure. Exposure is used in the calculation of the injury rate (how often per opportunity). The number of exposures (total counts) will be recorded. The injury rate will be calculated as the number of injuries divided by the number of exposures × 1000 (e.g., 2.3 injuries per 1000 Dance Exposures).

For the comparison of other studies that used dance hours in the calculation of the injury rate, total dance time will also be recorded in hours. The injury rate will also be calculated as the number of injuries divided by total dance hours × 1000 (e.g., 3.2 injuries per 1000 Dance Hours)., Upon completion of the three-month injury surveillance|Total Number of Musculoskeletal Complaints, For those events that do not rise to the level of a reportable injury event within the surveillance system, the term "musculoskeletal complaint" should apply., Upon completion of the three-month injury surveillance|Anatomical Distribution of Injuries, The distribution of injuries obtained by using the marking method on the human body diagram will be expressed as a percentage (% of total injuries) according to the injury site (e.g., %30 knee, %20 low back, etc.)., Upon completion of the three-month injury surveillance
Other Outcome Measures: Height, It will be measured in centimeters with a wall-mounted stadiometer., At baseline|Weight, It will be measured in kilograms with a body composition analyzer., At baseline|Body Mass Index (BMI), Height measurements will be converted from centimeters to meters for the calculation. BMI will be calculated as weight (in kilograms) / height (in meters) x height (in meters)., At baseline|Body Fat (BF), It will be measured with a body composition analyzer and shown as a percentage (%)., At baseline
