Comment on: “Revised Approach to the Role of Fatigue in Anterior Cruciate Ligament Injury Prevention: A Systematic Review with Meta-analyses”

Reply to Koller and Schobersberger: Comment on: “Revised Approach to the Role of Fatigue in Anterior Cruciate Ligament Injury Prevention: A Systematic Review with Meta‐analyses”

“…Thank you for the opportunity to respond to Dr. Koller and Dr. Schobersberger's letter [1] concerning our article "Revised Approach to the Role of Fatigue in Anterior Cruciate Ligament Injury Prevention: A Systematic Review with Meta-analyses" [2].…”

“…Koller and Schobersberger provide an in-depth overview of the physiological demands related to prolonged eccentric contraction and question if an increase in overall anaerobic and aerobic fitness may offer protection to the athlete against injury [1]. While we appreciate their in-depth overview, it was primarily related to skiing.…”

“…Given these characteristics, we are not sure how "The forced lengthening of an activated skeletal muscle has been termed eccentric contraction, which is essential, for example, for opposing the high centrifugal forces experienced by skiers in carved turns" [1] is related to non-contact anterior cruciate ligament injury prevention in ball team sports. Koller and Schobersberger refer to a study by Kamandulis et al [11] that describes the force depression after mechanically demanding eccentric contractions.…”

Injuries in Aerobic Exercise: Causes and Preventions

“…However, the human skeletal muscle detaches from the acetabulum and pushes towards the lower part of the joint capsule. 1 If the external force acts on the knee joint from the front and then travels along the femur to the femoral head, it is very easy to cause skeletal muscle dislocation and injury. Studying the force characteristics of skeletal muscle in aerobics exercise and analyzing its influence on ligament injury can guide the treatment of aerobics exercise muscle and ligament injury.…”
