Repetitive bout of controlled soccer heading does not alter heart rate variability metrics: A preliminary investigation.

Objectives: There is elevated unease regarding how repetitive head impacts, such as those associated with soccer heading, contribute to alterations in brain function. This study examined the extent heart rate variability (HRV) and cardiac baroreceptor sensitivity (BRS) metrics are altered immediately following an acute bout of soccer heading.

Methods: Seven male elite soccer players (24.

An acute bout of controlled subconcussive impacts can alter dynamic cerebral autoregulation indices: a preliminary investigation.

Objectives: There is growing concern repetitive head contacts sustained by soccer players may lead to long-term health ramifications. Therefore, this preliminary investigation examined the impact an acute soccer heading bout has on dynamic cerebral autoregulation (dCA) metrics.

Methods: In this preliminary investigation, 40 successful soccer headers were performed in 20 min by 7 male elite soccer players (24.

An Acute Bout of Soccer Heading Subtly Alters Neurovascular Coupling Metrics.

The current investigation examined how a bout of soccer heading may impact brain function. Semi-randomized crossover cohort. Controlled soccer heading.

Attention Is Required to Coordinate Reaching and Postural Stability during Upper Limb Movements Generated While Standing.

In the present study we investigated how attention contributes to the interaction between reach planning and execution, and postural control. Reaching movements were generated while standing and were performed either in isolation or in conjunction with a secondary reaction time (RT) task. In addition, to better understand how online movement control is affected by this interaction, the reaching movements could be unexpectedly perturbed medial-laterally.

Heading in soccer increases serum neurofilament light protein and SCAT3 symptom metrics.

Objectives: To determine the effect of heading a soccer ball on serum neurofilament light (NF-L) protein, plasma tau protein and symptom metrics including total number of symptoms reported and symptom severity scores on the Standardized Concussion Assessment Tool- 3rd edition (SCAT3).

Methods: Eleven male collegiate soccer players were recruited to take part in three experimental conditions including heading, sham and control conditions. Participants were required to perform 40 headers in 20 min in the heading condition, and control 40 soccer balls directed at them with their hands, chest or thigh in the sham condition.

A History of Concussion Does Not Lead to an Increase in Ocular Near Point of Convergence.

Ocular near point of convergence (NPC) has been shown to be sensitive to the effects of concussion and subconcussive impacts. To determine if NPC is also sensitive to a previous history of concussion, male contact-sport athletes either with (n=26) or without (n=16) a history of at least one previous concussion had their NPC assessed. The results showed that participants with a history of concussion displayed NPC values (9.
