“…Part of the rise in popularity has been through an increased international presence (14). As "the fastest game on two feet", lacrosse is characterized by frequent and repeated sprint efforts throughout the 30-minute halves that make up regulation time in college women's lacrosse (5). These repeated sprint efforts and general speed associated with the sport have contributed to its growing appeal.…”

External load has become a common metric for coaches to track the activity profiles of athletes during training and competition. The advent of wearable technology has made external load monitoring accessible for more coaches. The purpose of this study was to compare positional (attack, midfield, and defense) and game (first half to second) external loads. An NCAA Division I women’s lacrosse team was recruited to wear triaxal accelerometers and GPS units during five non-conference games during the 2020 regular season. The external load metrics evaluated for this study included total distance, sprint distance (> 19 km∙hr-1), number of power plays (> 3 m·s-2), top speed, and PlayerLoad. Significance was set at p < 0.05. No significant differences among positions were observed for full game measures (p > 0.05). A significant main effect for time was observed for sprint distance (midfield; p < 0.001 ) and power plays (midfield; p < 0.001 and defense; p = 0.004). While no significant differences occurred for activity profiles among positions, high-intensity efforts (sprint distance and power plays) were significantly less in the second half, likely due to fatigue. Coaches and sports scientists can use this information to manage in-game fatigue through tactics such as strategic substitutions and time-outs, thus preserving the intensity of the activity profiles late in the game.

“…Reactive strength is a specific power quality that is related to an athlete's ability to produce power in a short and fast stretch-shortening cycle [16]. Reactive strength underpins movements such as jumps from a run-up, sprinting at maximal speeds and changing directions while jumps from a run-up are not common in lacrosse sprinting and changing directions are common movements amongst specific position groups [1,2]. Therefore, it is somewhat surprising that this specific power quality did not differ between groups of higher and lesser contributors.…”

“…Lacrosse is a high intensity invasion sport that requires athletes to perform sprints, changes of direction and execute skills such as passing and shooting often while undertaking bodily contact [1,2]. Lacrosse is considered the fastest growing sport in the United States and as such participation rates across all levels of competition are increasing substantially.…”

Discriminative Ability of Lower limb Strength and Power Measures in Lacrosse Athletes

The objective of this investigation was to compare isokinetic strength, countermovement jump and drop jump variables between high-contributors and low-contributors within NCAA Division I Men’s and Women’s lacrosse athletes. Men’s (N=36) and Women’s (N=30) NCAA Division I Lacrosse athletes completed strength testing of the quadriceps and hamstring across three speeds (60°·s-1, 180°·s-1, 300°·s-1), countermovement and drop jumps. To determine the discriminative ability of select lower-limb strength and power characteristics participants were categorised as high-contributors (Males N=18, age=20.3±0.4yrs, height=183.9±5.5cm, mass=90.8±5.8kg; Females N=15, age=20.8±0.8yrs, height=169.3±6.7cm, mass= 64.1±7.2kg) or low-contributors (Males N=18, age = 19.5±0.2yrs, height = 184.1±5.6cm; mass = 87.9±8.1kg; Females N=15, age=19.7±0.2yrs, height=169.8±7.0cm, mass=62.9±7.7kg ) based upon the number of games the participants competed in during the regular season. Within the male cohort, moderate significant (p<0.05) differences were observed between high-contributors and low-contributors in isokinetic hamstring strength of the left leg at 300°·s-1 (d = 0.69) and peak power in countermovement jump (d=0.68). Within the women’s cohort a large (d=0.87) significant difference (p<0.05) in isokinetic strength of the left hamstring was observed between high-contributors and low-contributors at 60°·s-1. Hamstring strength and lower-limb power are important strength measures for lacrosse performance and should be prioritised in training prescription for lacrosse athletes.

“…An investigation of knee injuries in Iranian male professional soccer players shows that anterior cruciate ligament is the most commonly injured ligament of the knee [2]. A review of physical profiling for lacrosse players in the United States shows ACL injury is one of the most common injuries [3]. Global positioning systems (GPS) wearable technology was suggested to monitor athletes' physical profiles in sport fields.…”

Anterior cruciate ligament (ACL) injury is one of major risks for most athletes. ACL injury can be caused by many risk factors such as anatomic risk factors, biomechanical risk factors and environmental risk factors. In this article, numerical and theoretical analysis is conducted to investigate biomechanical risk factors. An entire threedimensional finite element knee model is built based on MRI data. Anterior Tibial Translations (ATT) at different knee flexion angles are simulated by finite element models. In the simulations, more attention is given to material properties of different knee components and their effects on ACL injury. Mechanical response of ACL during sport activities is highly determined by its viscoelastic properties. Unfortunately, viscoelastic properties of two bundles of ACL will change dramatically even with several hours' physical aging. As a consequence, ACL will experience mechanical ductile to brittle transition due to daily physical aging. Theory of physical aging from polymer science is, for the first time, introduced to understand ACL injury and its prevention. By analogy to physical aging of amorphous polymer materials, we think physical aging of two bundles of ACL will largely increase risk of ACL injury. Besides, physical aging will also build a heterogeneous stress and strain in ACL due to its natural anatomic structure, which is a large risk for athletes. The specific designed prevention programs for ACL injury such as plyometrics, strengthening and other neuromuscular training exercises [1] are believed to erase physical aging of ACL. ACL with less physical aging is less likely to get injured in sport activities. In this article, a virtual physical aging simulation is built to validate current hypothesis. Erasing physical aging of ACL may provide an accurate and quantitative way to prevent ACL injury.lobal Journal of Researches in Engineering ( ) Volume Xx X Issue I Ve rsion I 43Year 2020 J Gl risks for most athletes.
