Optimal integration of kinematic and ball-flight information when perceiving the speed of a moving ball

In this study, we examined the degree to which kinematic and ball-flight information are integrated when estimating ball speed in baseball batting. Thirteen university level baseball batters performed a ball-speed evaluation task in a virtual environment where they were required to determine which of two comparison baseball pitches (i.e., a reference and comparison stimuli) they perceived to be faster.

Relevance and Effectiveness of Combined Resistance and Balance Training to Improve Balance and Muscular Fitness in Healthy Youth and Youth Athletes 

The objective of this scoping review was to describe the effects of concurrently performed balance and resistance training (i.e., metastable resistance training) and different sequencing schemes of balance and resistance training on measures of balance and/or muscular fitness in healthy youth and youth athletes. We additionally aimed to identify knowledge gaps in the literature.

How much resistance exercise is beneficial for healthy aging and longevity?

While optimal volumes of endurance-type exercise (aerobic moderate‐to‐vigorous PA (MVPA)) to reduce mortality from all causes have been suggested to amount to or even exceed 700 min per week, recent meta-analyses suggest that large amounts of RE may be associated with adverse outcomes.

Unanticipated fake-and-cut maneuvers do not increase knee abduction moments in sport-specific tasks:

Implication for ACL injury prevention and risk screening In team sports, the majority of ACL injuries are non-contact in nature, with a subset of these occurring during cutting maneuvers. Young female handball players are at greater risk than their male counterparts. Athletes participating in ball sports are constantly challenged by interacting with teammates and reacting to opposing players while performing highly dynamic cutting maneuvers, both with and without handling a ball. In handball, video analysis suggests ACL injuries frequently occur during fake-and-cut situations.

Normative values and changes in range of motion, strength, and functional performance over 1 year in adolescent female football players 

Normative values for ROM and strength assessments of neck, back, trunk, hips, knees, calves and ankles are presented for adolescent female football players. Generally, fluctuations in ROM were small with little clinical meaning, whereas strength improved over 1 year.

Daily fluctuations in visual motion discriminability contribute to daily fluctuations in continuous visuomotor performance

In ball games such as table tennis, in which a ball moving at high speed is hit, the visual system in the brain processes the motion information of the ball to predict the arrival point and form a motor command for directing the racket there. Therefore, the quality of the visual information processing is an important factor in determining the quality of the physical movement that is subsequently performed.

Identifying current uses of return to work screening tests and their effectiveness of reducing the risk of reinjury in athletic occupations 

The results demonstrated very low level of certainty for the effectiveness of screening tests reducing the risk of reinjury. A gap in our understanding currently exists for the effectiveness of RTW screening tests in tactical athletic occupations following injury and further research investigating is required.

Timed “Max Effort” 

Strength is important for every athlete, but even more crucial is displaying it over the course of time. For anaerobic dominant athletes, the ability to access strength immediately and accelerate through range of motion (ROM) is paramount. For the glycolytic-aerobic dominant athlete, maintaining output over the course of the event is key.

Wearables for Running Gait Analysis: A Systematic Review

It is well established that a contributing factor to RRI is abnormal running gait, meaning early detection of potentially harmful running gait pathologies is essential. Where biomechanics have been implicated, clinical running analysis has largely been limited to the use of subjective clinical observation or rating scales, which may not be sensitive to subtle changes in performance with training or injury

Exogenous Ketone Supplements in Athletic Contexts: Past, Present, and Future 

Of particular relevance to athletes are the metabolic actions of ketone bodies to alter substrate utilisation through attenuating glucose utilisation in peripheral tissues, anti-lipolytic effects on adipose tissue, and attenuation of proteolysis in skeletal muscle. There has been long-standing interest in the development of ingestible forms of ketone bodies that has recently resulted in the commercial availability of exogenous ketone supplements (EKS).

Prevalence, frequency, adverse events, and reasons for analgesic use in youth athletes

Analgesics are commonly used in youth athletes, but estimates vary depending on type of analgesic and prevalence measure. As the majority of studies were of poor methodological quality, future high-quality research should include prospective data collection of analgesic use to understand consumption trajectories.

The Acute and Chronic Effects of Implementing Velocity Loss Thresholds During Resistance Training

Velocity loss (VL) experienced in a set during resistance training is often monitored to control training volume and quantify acute fatigue responses. Accordingly, various VL thresholds are used to prescribe resistance training and target different training adaptations. However, there are inconsistencies in the current body of evidence regarding the magnitude of the acute and chronic responses to the amount of VL experienced during resistance training.
