Brief Summary

Rink Hockey is a sport played on a 40\*20 metres rink characterized by combined periods of high intensity and short breaks, there´s a lack of epidemiological studies in this field. In line with the well-established model of sports injury prevention research proffered by van Mechelen, the first stage in this process is establishing the extent of the problem i.e. injury incidence, severity and burden.

Detailed Description

This study will assess performance metrics from rink hockey athletes and injury epidemiology. 4 tests (to be specified yet) will evaluate players fitness during preseason and when a player suffers a non-contact injury during the season, the player will be retested to assess variability and performance deficits.

injury characteristics and exposure time will be recorded too

Primary Outcome Measures

Name	Time	Method
Explosive strength test (Countermovement jump test)	september 2022 to june 2023	capacity of the athlete to display lower body explosive strength. it is measured with a slow motion camera and the app MyJump. The result is expressed in cm.; The athlete performs a vertical jump as fast as possible with their hands around their waist
cardiovascular fitness test (30-15 test)	september 2022 to june 2023	this test aims to assess cardiovascular capacity of the athlete. the athlete runs at a certain pace (marked by an audio) along a 28m track. every time there is a beep the athlete must have completed the corresponding distance. every 30 seconds the speed increases and therefore the athlete must run faster. the result is the last speed the participant was skating at. when the participant fails to reach the corresponding distance 3 times, gets eliminated
injury incidence	september 2022 to june 2023	number of injuries observed during the season 2022-2023
Maximal strength capacity	september 2022 to june 2023	The RM maximal resistance for the squat exercise will be estimated by performing the squat exercise with different weights and measuring barbell movement speed. Measuring the barbell speed we can estimate the 1RM since it follows a linear relationship with the weight the athlete must lift. Therefore, the higher the weight, the slower the barbell will be moved. 1RM is considered the weight moved at .2m/s by the participant.The value will be expressed in kilograms
Agility test (5-10-5 test)	september 2022 to june 2023	agility test for the lower body. three cones separated by 5 metres each. the participant starts in the middle cone, runs to one edge (5 metres) and then brakes and runs to the other (10 metres) to brake again and come back to the middle cone. the result is expressed in seconds that the participant needs to complete the test. the test is performed in skates.

Secondary Outcome Measures

Name	Time	Method
tissue affected	september 2022 to june 2023	Injuries can affect different tissues in the body. The International Olympic Committee differs between muscle, ligament, tendon, nerve or bone injuries (among others: skin or central nervous system). Tissue injured will be analyzed to assess wether a certain tissue is more predisposed to getting injured than others.
mechanism of injury	september 2022 to june 2023	Injuries can be cathegorized between contact and non-contact, in this study only non-contact lower body injuries will be analyzed. This information will be collected to assess which gesture provoked the injury (sprint, side brake, etc) and evaluate which specific movement is more injurious in this sport
injury burden	september 2022 to june 2023	lay-off days due to the injury
region injured	september 2022 to june 2023	which body region was injured (lower limb only) according to the International Olympic Committee consensus statement
