Evaluation of the Functional Movement Screen and a Novel Basketball Mobility Test as an Injury Prediction Tool for Collegiate Basketball Players


Identifying injury risk and implementing preventive measures can assist in reducing injury occurrence and may ultimately improve athletic performance. Improper movement patterns often contribute to musculoskeletal (MSK) injuries. The validity of the Functional Movement Screen (FMS™) as an injury prediction tool for athletes remains unclear. We designed the Basketball-Specific Mobility Test (BMT) to represent the neuromuscular demands of basketball and identify deficiencies that may be indicative of greater MSK injury risk while playing this sport. The aim of this study was to examine the association of FMS™ and BMT scores with injury occurrence in collegiate basketball players. We hypothesized that the BMT would be a better predictor of injury risk than the FMS™, and that scores from both tests would have a higher association with severe MSK injuries than minor, non-MSK injuries. One-hundred nineteen male and female collegiate basketball players from four Upper Midwest universities were assessed pre- (PRE) and post-season (POST) using the FMS™ and BMT. In-season injury records were collected from the schools’ athletic trainers and were classified by type and severity. During the season, 56 of 119 players were injured, resulting in 96 total injuries. Injured athletes’ PRE FMS™ scores demonstrated negligible effects compared to uninjured athletes’ PRE scores (d 0.20). While specificity of the FMS™ and BMT to predict injury was relatively high (FMS™ 85.7-87.6; BMT 42.0-88.0), sensitivity (FMS™ 14.2-22.7; BMT 11.6-39.1), odds ratios (FMS™ 1.00-2.08; BMT 0.47-1.06), and injury prediction capacities (AUC; FMS™ 0.43-0.49; BMT 0.49-0.59) of the tests were low. Although the FMS™ and BMT may be suitable for identifying MSK deficiencies, they do not accurately determine injury risk in collegiate basketball players. Injury risk assessments may be improved by targeting specific injury mechanisms and the conditions in which they occur.

Kinetic Contributions of the Upper Limbs During Counter-Movement Vertical Jumps With and Without Arm Swing

This study examined the kinetic contributions of the upper extremities during counter-movement vertical jumps (CMVJ) while using arm swing (AS) or no-arm swing (NAS) conditions. Fourteen healthy men (X¯±SD; age = 24.1±3.9 yrs) volunteered for this investigation. Subjects performed in random order a total of 6 jumps consisting of 3 AS and 3 NAS CMVJ. A motion capture system was used to analyze the kinetic data. Paired samples t-tests were used to examine the subjects’ mean differences in the AS and NAS CMVJ trials (p<0.05). Results for all subjects were determined for each jump performed, with statistical analyses performed on mean values for all three jumps per subject. The AS significantly increased the vertical jump height (VJH) by an average of 0.07±0.03 m (3.0±1.3 in). DXA scans determined the upper limbs were 12.0% of the total body mass. Movement of the upper limbs during the AS CMVJ produced 32.2±7.0% of the total mean ground reaction force (GRF), and 11.3±2.2% during the NAS CMVJ. The enhancement of performance when jumping using an AS resulted in a 13.6% increase in VJH. The contribution of the upper limbs during the AS CMVJ averaged 31.5% of the peak GRF which occurred immediately before takeoff. The upper extremities can greatly influence vertical jump performances and the accompanying kinetics. When analyzing jump GRFs, one must be aware of how much the upper limbs contribute to these forces. Additionally, proper arm swing mechanics must be emphasized when instructing correct jump technique.

Oxidative Stress Parameters and Its Associations With Arterial Stiffness in Competitive Powerlifting Athletes After 12-Week Supervised Strength Training

Jürgenson, J, Serg, M, Kampus, P, Kals, J, Zagura, M, Viru, M, Zilmer, K, Zilmer, M, Eha, J, and Unt, E. Oxidative stress parameters and its associations with arterial stiffness in competitive powerlifting athletes after 12-week supervised strength training. J Strength Cond Res XX(X): 000–000, 2019—Available studies have not revealed a clear understanding of the impact of intensive strength training on arterial stiffness and oxidative stress (OxS) parameters, which may have a significant impact on further cardiovascular health of an athlete. The purpose of this study was to evaluate the effect of a 12-week supervised strength training program (SSTP) on oxidative stress indices and its relationship with arterial stiffness in powerlifting athletes. A total of 19 men (28 ± 6 years) exercised for 12 weeks (4 days per week with intensity 60–90% assessed from 1 repetition maximum, 90–120 minutes per session). Oxidative stress parameters and arterial stiffness (SphygmoCor 7.1) were measured before and after SSTP. The study results showed that total peroxide concentration increased and total antioxidant capacity decreased significantly after SSTP. There were no significant changes in carotid-femoral pulse wave velocity (cfPWV) or in the augmentation index. Correlation analysis revealed that the magnitude of the increase of cfPWV was significantly related to the increase of OxS. The current study demonstrated that a 12-week SSTP in powerlifting athletes produced significant changes in OxS indices, which were positively related to increased aortic stiffness. This novel finding may have significant implications about the effect of OxS on cardiovascular health after high-intensity strength training. Furthermore, strength and conditioningcoaches may have to consider the long-term exercise-induced changes in OxS on an individual level, where increased OxS leads to impaired arterial stiffness and cardiovascular health.

Salary Survey Shows It Pays To Work In Additive Manufacturing

Global talent distribution in the 3D printing industry [Image: ADG]

Alexander Daniels Global’s third annual Additive Manufacturing Salary Survey is available.

We love a good industry survey.

Awareness of the who behind the what is invaluable. That’s why every year we check in on our own community, and share those results; understanding who we’re talking to helps us to have a better conversation. Surveys within the industry itself are full of poignant findings, and we also encourage participation in these.

Alexander Daniels Global (ADG) is specifically focused on the people of the industry. That is, the personnel. The company is a recruitment specialist for additive manufacturing (AM), working with 3D printing businesses and staffs around the world.

The nearly four-year-old company recently released its third Salary Survey to examine “additive manufacturing specific trends, salary, hiring intentions, and in-demand skills and roles.” Published results are based on responses “from AM employers and more than 5,000 AM professionals across machinery OEM’s, material companies, software companies, and industrial companies adopting additive manufacturing.”

Drawing upon direct feedback from these thousands of professionals as well as released findings from Sculpteo’s latest State of 3D Printing report as well as the 2018 Wohlers Report, the Salary Survey is well positioned to create a trustworthy shape of additive manufacturing.

Understanding the dynamics at play — who’s being hired where for what position, why they might move to another position, where the need is greatest for more talent — provides a fuller picture of what’s happening in 3D printing today.

ADG examines several different disciplines within the broad scope of additive manufacturing, looking into regional and seniority-driven trends in:

  • R&D and Engineering

  • Sales

  • Service

  • Applications & Consulting

  • Marketing

  • Software

“The industry is ever evolving and new companies and technologies spring up every day, demanding more and more personnel to help the businesses expand their AM divisions and overgo competitors. This has, over the years, resulted in an immense pressure on the AM talent pool, and there is a severe gap between the talent demand from employers and the talent supply, i.e. the number of available professionals,” ADG’s Social Media & Marketing Manager, Signe Damgaard, explains.

The talent gap is well known as one of the barriers facing additive manufacturing today. Getting past that as a generality and digging into where the gap is and what it actually looks like can paint a more useful picture for companies hoping to fill their own gaps.

To quantify that talent gap, Damgaard goes on to say:

“According to Alexander Daniels Global, there are only 12 active candidates, globally, for every AM job advertised. The study goes on arguing that even though this number may seem high, it really is not, when you take into account those 12 people could be based anywhere in the World and be from any discipline. Considering these factors, the actual relevant active talent pool per job is far smaller, maybe even as low as 1 or 2 relevant active candidates per role, but even still, they are unlikely to be based in the same location as the job being advertised.”

Overall, the intent of the report is to both “make the industry more transparent” and “provide both AM professionals and AM employers with a guideline for proper remuneration.” (Salary, fairly unsurprisingly, proved to be the most-often-cited motivation for professionals moving on to a new job, ahead of career progression and new challenges.)

So how does pay in additive manufacturing compare?

A large majority of respondents (83%) said that AM salaries are at least similar to those in other industries, with nearly half of that majority (37% of the total) calling salaries in AM “competitive or very competitive” when compared with similar industries. Growth of these salaries is also comparable to other increases in traditional manufacturing, at an average of 3.9%. The largest gains in salary (in the US) were in sales (14.5%) and software (11.9%), with these figures excluding C-level positions.

Also included within the scope of the report are more region- and position-focused data, roles in demand, stats on why people want to change jobs, what makes an employer appealing for a potential employee, and exploration of the talent shortage.

Drawn from data of those currently working in AM, the report also presents a breakdown of experience, from under two years to more than 10 years, and a look at gender distribution. On the experience side, the largest segment (42%) of employees have been in AM for between two and five years. This section is a fairly regular distribution, looking generally like a typical bell curve. Unfortunately, the 2018 findings showed a drop in women as a percentage of the total, with the latest results showing 11% female and 89% male employees. (The 2017 report showed 13% female.) Presumably the drop is in percentage alone due to a growing industry, rather than a drop in actual numbers.

The Salary Survey is a relevant and helpful report to look into the shape of those shaping additive manufacturing. HR managers, growing companies, and large players alike will find value in the findings, as the experienced team at ADG digs into how to both attract and retain talent. Employees may find the actual salary ranges cited (for EMEA, APAC, and US) in minimum, average, and maximum figures at various levels of experience/seniority, to see how their employer or new offer compares.

I also find the report a valuable reference in writing my own Diversity for Additive Manufacturing report for Women in 3D Printing, with the next edition to be released very soon.

ADG provides the Salary Survey as a free download, and it is well worth the read.

Postactivation Potentiation and Change of Direction Speed in Elite Academy Rugby Players

This study investigated the effect of preceding pro-agility sprints with maximal isometric squats to determine if postactivation potentiation (PAP) could be harnessed in change of direction speed. Sixteen elite under-17 rugby union players (age: 16 ± 0.41yrs; body mass: 88.7 ± 12.1kg, height: 1.83 ± 0.07m) from an Aviva Premiership rugby club were tested. Subjects performed a change of direction specific warm-up, followed by two baseline pro-agility tests. After 10 minutes recovery, 3 x 3-second maximal isometric squats with a 2 minute recovery between sets were completed as a conditioning activity (CA) on a force plate where peak force and mean rate of force development over 300 milliseconds were measured. The pro-agility test was repeated at set time intervals of 1, 3, 5 and 7 minutes following the CA. Overall pro-agility times were significantly slower (p < 0.05) at 1-minute post-CA compared to the baseline (3.3%), with no significant differences occurring at 3, 5 or 7 minutes post-CA. Therefore, it appears that performing multiple sets of maximal isometric squats do not enhance pro-agility performance.

Oxygenation Responses While Wearing the Elevation Training Mask During an Incremental Cycling Test

Romero-Arenas, S, López-Pérez, E, Colomer-Poveda, D, and Márquez, G. Oxygenation responses while wearing the elevation training mask during an incremental cycling test. J Strength Cond Res XX(X): 000–000, 2018—The Elevation Training Mask 2.0 (ETM) is a commercial training mask that purportedly simulates altitude training, although their effects have not been conclusively demonstrated. Therefore, the purpose of this study was to evaluate the influence of wearing the ETM on muscle and brain oxygenation responses during a maximal incremental cycling test, as well as the influence of this device on the heart rate (HR) response, perception of effort (rating of perceived exertion [RPE]), arterial oxygen saturation (SaO2), blood lactate (La+), and performance (POpeak). Fourteen active males completed an incremental cycling test to volitional exhaustion in 2 separate and counterbalanced conditions, wearing the mask set at 9,000 feet (i.e., 2743 m) and a control condition (CTR, without ETM). During the trial, muscle and cerebral oxygenation were monitored continuously using near-infrared spectroscopy. Heart rate, RPE, and SaO2 were also recorded from the beginning of the test until the volitional exhaustion. La+ was measured at the end of each test. Wearing the ETM significantly reduced the POpeak by −6.9 ± 6.6% (p = 0.002) and this was accompanied by lower La+ values (−12.8 ± 21.6%; p = 0.027). SaO2 was also significantly lower at maximal intensity in comparison with the CTR condition (−1.5 ± 0.3%; p = 0.028). However, both HR and RPE showed a similar trend during both sessions, as well as muscle oxygenation. Nevertheless, the mask caused an increase in brain oxygenation compared with the CTR condition (p < 0.05). In conclusion, our findings suggest that wearing the ETM causes a pronounced increase in O2Hb and tHb in the frontoparietal cortex without any change in the muscle oxygenation.

Species-specific pathogenicity of severe fever with thrombocytopenia syndrome virus is determined by anti-STAT2 activity of NSs [Virus-Cell Interactions]

Severe fever with thrombocytopenia syndrome virus (SFTSV) is a novel emerging virus that has been identified in China, South Korea, and Japan, and induces thrombocytopenia and leukocytopenia in humans with a high case fatality rate. SFTSV is pathogenic to humans, while immunocompetent adult mice and golden Syrian hamsters infected with SFTSV never show apparent symptoms. However, mice deficient for the gene encoding the α chain of the interferon (IFN) α and β receptor (Ifnar1-/- mice) and golden Syrian hamsters deficient for the gene encoding signal transducer and activator of transcription 2 (Stat2-/- hamsters) are highly susceptible to SFTSV infection, with infection resulting in death. The nonstructural protein (NSs) of SFTSV has been reported to inhibit the type I IFN response through sequestration of human STAT proteins. Here, we demonstrated that SFTSV induces lethal acute disease in STAT2-deficient mice, but not in STAT1-deficient mice. Furthermore, we discovered that NSs cannot inhibit type I IFN signaling in murine cells due to an inability to bind to murine STAT2. Taken together, our results imply that the dysfunction of NSs in antagonizing murine STAT2 can lead to inefficient replication and the loss of pathogenesis of SFTSV in mice.

IMPORTANCE Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by SFTS virus (SFTSV), which has been reported in China, South Korea, and Japan. Here, we revealed that mice lacking STAT2, which is an important factor for antiviral innate immunity, are highly susceptible to SFTSV infection. We also show that SFTSV NSs cannot exert its anti-innate immunity activity in mice due to the inability of the protein to bind to murine STAT2. Our findings suggest that the dysfunction of SFTSV NSs as an IFN antagonist in murine cells confers a loss of pathogenicity of SFTSV in mice.

If you have never bought earbuds with mic before, then you can take a look at our list of buying considerations. You’ll see a number of things that must be considered before you make a purchase. The number of features available is what makes the difference between one option and another.

Microphone quality

Because this buying guide is all about earbuds with a microphone, then naturally your number one consideration might be the quality of the mic. You shouldn’t expect the mic to be of the same quality as that of a smartphone or a gaming headset. However, different earbud models come with a variety of audio microphone qualities.

You should also pay attention to the ergonomics of how the mic has been implemented. For example, where is it located on the wire, and are there any buttons that can be used in order to adjust the volume? Some microphones suffer from low volume problems, which means the ability to increase the mic volume is very much appreciated.

You’ll find that all of the microphone options on this list are good enough to make calls and speak to friends via different social media platforms. We have selected the best options so that you don’t have to be frustrated with inferior mic quality.

Material used and durability

Earbuds are typically used when you are outdoors and durability can be an issue when the materials used are not of good quality. Therefore, pay attention to the design in terms of how strong the materials are so that you can be confident longevity will be assured.

One way of figuring this out is by taking a peek at the length of the warranty that’s provided. When a long warranty is offered, then you can be confident that the company believes in the product they are selling. Therefore, you can rely on the durability and if it does break sooner rather than later the warranty can be used.

Audio quality

Earbuds can come with a wide array of features nowadays such as noise-cancellation and a sweatproof design, but the audio quality should not be sacrificed upon. After all, the primary purpose of earbuds is to play audio and that is the biggest factor that should be used when judging the product.

The frequency response and audio drivers are something that you need to pay attention to. When it comes to earbuds, an in-ear design is preferred as the noise isolation feature will be enhanced. This feature essentially drowns out the audio of the surrounding environment, which in turn reduces the amount of distortion experienced. Also if you’re taking a call, then noise isolation allows you to hear the other person much better in a noisy environment.

Wired or wireless

Are you easily irritated when there is a long wire that gets tangled up or simply gets in the way? Then you should opt for a wireless design or one where there is a minimal amount of wires. This approach has a higher degree of freedom and is especially suited for instances where you need to exercise. However, the downside of a wireless approach is that you need to recharge the battery. After years of use, the battery quality might become poor or stop working altogether.

On the other hand, a wired approach might not provide the same level of freedom, but there is no need to worry about recharging a battery. Also, the quality of the audio stability might be better. However, this does depend on which two specific earbuds you are comparing.

Ergonomic design

A number of features can be added that allows you to have a better experience. For instance, when a number of different eartip sizes are included, then you can get the right fit for your ears. Consequently, you will not have to worry about the earbuds falling out of your ears or becoming loose.

The placement of the different elements is also important. For instance, the microphone should be at a reasonable distance down the line so that you do not have to even bother adjusting the wire in order to speak. The placement of the button should also be convenient, and the 3.5mm head should have a thin design so that it can easily be inserted into the audio playing device.

Sweatproof

Are you going to be using your earbuds while engaged in physical exercise? Then you need to take advantage of the various sweatproof designs available. It would be counterproductive if your earbuds were to break simply because of sweat getting inside the casing. There are a number of sweatproof designs nowadays that makes selecting a suitable option fairly straightforward.

Hands-free calls

Do you require a solution to make and receive calls in a hands-free format? Then earbuds with a mic is a great product to buy because they are relatively inexpensive and provide you with a great audio experience. Unlike when using the phone, the earbuds are directly in the ear canal. This means you’ll hear the audio at much greater detail. This is especially true if you decide to opt for a model where the noise isolation feature is present.

Give as a present

Are you in the process of doing some shopping for presents, but have no idea what to buy? Earbuds are one of the most versatile products out there as they can be used for a wide number of applications. This means it is a safe bet that the recipient of such a present will find a use for them and appreciate the present. Even if they happen to own a pair already a backup option would not go amiss.

For the gym or jogging

Earbuds are a great solution while you are working out and want an audio solution. The lightweight nature and portable aspect are what appeals to those that are working out. Also, the number of options that are sweatproof is increasing because companies are recognizing the fact that many users of their products use them for exercise.

Furthermore, when you add a microphone to the mix and you have an option to take calls while you are working out. This means you do not have to stop, which is ideal if you are pressed for time and want to not lose momentum during the workout but also want to answer the call.

Editor’s Rating: 4.6/5

A one button design means you can answer calls in a straightforward manner. It can also be used to cycle through music tracks and pause/play music. This minimalist yet effective design is a big advantage for those that do not want to fiddle around with multiple buttons. The mic quality is decent for budget earbuds.

This is a wireless setup, which means you have a great degree of freedom when using them. The battery life is 6 to 7 hours and the quality of the Bluetooth performance is great.

However, it is not flawless, which means you can experience a minimal level of disruption in the audio quality at times. The audio quality delivers what can be described as a fun sound that has powerful bass, but also at low volumes the level of detail is excellent. Where this product suffers is the clarity at the high volumes compared to some of the competition.

One of the biggest attractions of this product is the competitive price at around $35. Typically the wireless nature combed with the great design fetches a much higher price tag of $80-100. What is lacking here is the audio quality and Bluetooth connection compared to a premium based product. However, for the budget price, you are getting decent value for money.

To conclude, the Skullcandy Smokin’ Buds 2 Wireless earbuds provide excellent value for the features. The biggest attraction is the wireless setup that comes with 6-7 hours and the functional microphone. Furthermore, if you like bass based audio, then you’ll enjoy what is offered here.

Effects of aquatic exercise on muscle strength in young and elderly adults: a systematic review and meta-analysis of randomized trials

The effects of training in an aquatic environment on muscular strength are still contradictory in the literature. The aim was to conduct a systematic review and meta-analysis of randomized studies about muscle strength responses after a program of aquatic exercise. A systematic review followed the Cochrane and PRISmA recommendations. The search was performed between December 2015 and January 2016. There were no language restrictions and PUBmED, SCOPUS, Scielo, Cochrane and PEDro databases were consulted. An analysis of eligibility of the studies was done by two independent authors. The data extraction followed standard criteria, and an evaluation of methodological quality was performed. The statistical analysis was conducted in Review Manager 5.1 software. The statistical heterogeneity was assessed by means of Cochran’s Q test and by the inconsistency test (I2). The search found 2563 manuscripts, 27 were included, totaling a total n of 1006 participants. The analysis of the risk of bias demonstrated a lack of clarity of the randomization process, allocation concealment, blinding assessment, intention to treat analysis and calculation of the sample in 70% or more of the studies analyzed. Meta-analysis demonstrated a significant increase in handgrip strength, in isometric peak torque of knee unilateral extension and flexion and isokinetic peak torque (60°.s-1) of knee unilateral extension. Sensitivity analyses demonstrated that the positive effects of training in an aquatic environment may be dependent on factors such as age, velocity of movement and use of device. Land-based and aquatic exercises seem to lead to similar muscle strength gains. Aquatic exercise should be recommended as a strategy to improve muscle strength, but new studies with better methodological quality should be conducted.

Effects Of Pre-Competitive Preparation Period On The Isokinetic Muscular Characteristics In World Class Handball Players

Authors: Olivier Maurelli oliviermaurelli@yahoo.fr +33 6 14 40
Copyright © 20-19 by the National Strength & Conditioning Association.
The aim of this analysis was to describe the effects of eight weeks of pre-competitive period preparation (Pc2P) on the isokinetic muscular traits from worldclass hand ball players. Nineteen male professional players (era: 26.6 ± 5.4 years) engaged in the study. Two bilateral isokinetic evaluations of knee-joint flexors (H; Hamstring) and extensors (Q; Quadriceps) were performed before and after Pc2P to ascertain the peak torque (PT), the signal power (MP) as well as the ratios (agonist/antagonist, dominant/non-dominant and combined). S 1 ) in concentric manner showed no substantial growth for the dominant nor non-dominant legs. For H, the results demonstrated a significant increase for both thighs (p < 0.001). At the greater velocity (240°. S-1), Q was significantly increased for the dominant (p < 0.005) and non-dominant legs (p < 0.002) as well as H for both sides (p < 0.001). Eccentric style (30°. S1 ) revealed a significant increase for dominant (p < 0.005) and non-dominant legs (p < 0.01). For MP, results revealed significant increase at low speed velocity (p < 0.003) and elevated angular velocity (p < 0.01) for both legs. In eccentric mode, values demonstrated a significant increase following Pc2P for dominant (p < 0.001) and non-dominant legs (p < 0.02). The ratios revealed significant growth for its agonist/antagonist ratio (AAR) at 60°. S1 for prominent leg (p < 0.003) as well as the non-dominant leg (p < 0.01). At 240°. S1 the worth revealed a significant gap for the sides (p < 0.02). In an accident hazard standpoint, along with optimizing performance, these results showed that eight weeks of Pc2P raised the muscle and strength power of global players, also when the ratios of their knee muscles didn't change during this period.
