Testing a new balance and reaction method for football players

This study tests a wearable device that measures how well you jump and keep your balance. It helps see if this device gives reliable results in healthy adults. Participating may help improve future balance and movement assessments.

This trial tests if a single session of watching and imagining arm movements can improve balance and reduce fatigue in healthy young men.

This study looks at how thinking skills affect balance in young adults who had ACL repair surgery in the past 5-7 months, compared to healthy young adults. You will do balance tasks and answer some questions.

This study compares two types of balance training to see which one better improves tennis players' ability to move quickly and change direction on court. You'll do either reactive balance exercises (responding to sudden movements) or traditional balance exercises over the study period.

This study looks at how the brain and thinking may be affected by playing professional football, using brain scans and thinking tests. It also compares former players with similar men who did not play organized football beyond high school.

This trial tests a type of training that challenges you to do two tasks at once to help with thinking and movement. It is for people over 55 who may have mild memory problems but do not have major brain, heart, or lung conditions.
