This study provides data on the peculiarities of adaptation of the cardiorespiratory system to muscle load in athletes engaged in certain types of martial arts (judo, Thai boxing, MMA, and jiu-jitsu). Changes in physiological indicators such as weight, height, vital capacity, glossopharyngeal inhalation (GI), blood pressure, heart rate, physical performance, endurance according to the physical work capacity test at a heart rate of 170 beats per minute (PWC 170) and membrane patch colorimetry (MPC) tests, and heart rate variability are shown, with the calculation of the main indices of the humoral-vegetative balance. The results showed that the vital capacity of the lungs and tidal volume in athletes were 6-8% lower than the required values and corresponded to the “average level” of the functional capabilities of the respiratory system. Calculations of the Skibinsky, Robinson, and Shapovalova indices showed a functional insufficiency in the adaptation of the cardiorespiratory system to physical activity. Against the background of the development of muscle strength functions, indicators of physical performance and endurance of athletes (PWC 170 and maximum oxygen consumption (MOC) tests) turned out to be “below average” levels in absolute and relative values. To identify hidden functional disorders of the cardiovascular system, variability studies were conducted on heart rate (HRV), the results of which showed that 60% of athletes (in all groups), regardless of the type of sport, had a good level of functional capability of the cardiovascular system. The remaining athletes revealed a low level of adaptation mechanisms and functional state of the cardiorespiratory systems, the reason for which was insufficient training of the body of endurance athletes. Research has shown that athletes who have not previously engaged in special training for endurance and increased performance need to develop cardiorespiratory capabilities that ensure the activity of metabolic processes and replenish energy reserves for successful sports activities.

The purpose of the study is the evaluation seeds diversity of different species in the genus Rhododendron after pre-sowing treatment with organic compounds. As the signs of the seeds diversity is understood the seed germination and the seedling height. The research was conducted at the B.M. Kozo-Polyansky Botanical Garden of Voronezh State University (geographic coordinates: E 39°12', N 51°42'; 168.2 meters above sea level), Central Chernozem region (chernozem soil) in 2019-2020. It has been used ornamental shrubs. The study was made about the pyrimidinecarboxylic acids effect on the seed germination and the seedling height of Rhododendron species. The diversity of seeds is manifested in their heterogeneity according to morphological characteristics (the seedling height) and sowing qualities (seed germination) of Rhododendron species. The sowing properties (germinating capacity, seedling growth) were improved after treating the seeds with the organic compounds. There is the trend of increasing the seed germination and the seedling height of Rhododendron depended on the concentration of applied compounds. The seed germination for Rh. ledebourii, Rh. luteum, Rh. molle was increased from 5 to 7%, for Rh. schlippenbachii – from 5 to 10%. The seed treatment with pyrimidinecarboxylic acids at concentrations 0.01%, 0.05% and 0.1% allows to increase the seedling height for Rh. ledebourii from 37.5 to 75%, for Rh. luteum, Rh. molle - from 18.2 to 45.5%, for Rh. schlippenbachii from 20 to 40% concerning the control. To increase the seedling height, 2-benzylamino-4-methylpyrimidine-5-carboxylic acid at concentrations 0.05% and 0.1% is most effective. Morphologically close Rhododendron species (Rh. luteum, Rh. molle) indicated similar reactions to the seed treatment with compounds of the pyrimidinecarboxylic acid series.

Authors: Kennedy June , Otley Thomas , Hendren Steph , Myers Heather , Tate Angela 
Published: January 2024

BACKGROUND Swimming is enjoyed by athletes of all ages, and shoulder pain is a common problem. Clinicians identify impairments which impact shoulder pain and these impairments may differ depending on the swimmer’s age competition level. PURPOSE The purpose of this study was to investigate objective measures utilized to assess swimmers and assess the relationship of test values to shoulder pain in distinct age groups/competition levels. A secondary aim was to report normative/expected values for these tests. DESIGN Systematic review METHODS PRISMA methodology was employed to assess studies evaluating clinical tests and measures associated with shoulder pain for swimmers in varied age competition levels. The Methodological Index for Non-Randomized Studies instrument was used to evaluate the quality of the included studies, and a qualitative synthesis of findings was conducted to determine the strength of the evidence in four age competition levels for nine objective measures. Distinct cut points for proposed measures were identified. RESULTS Twenty-seven studies were included in the analysis and the majority were of moderate quality in adolescent/adult swimmers. Youth swimmers had limited evidence for the development of shoulder pain associated with scapular position/dyskinesia, weakness of periscapular muscles, low endurance of core muscles, and moderate evidence for shoulder pain associated with laxity and altered range of motion (ROM). Adolescent/adult swimmers demonstrated limited evidence for a positive association between developing shoulder pain if there is a low eccentric ER:concentric IR ratio, and moderate evidence for pectoralis minor tightness and glenohumeral laxity. There were limited studies regarding masters swimmers to derive conclusive evidence. Cut points were identified from the included studies but these have not been validated in other studies. CONCLUSION Swimmers of various ages may have different objective clinical tests and measures associated with the risk for developing shoulder pain. More studies are needed to fully understand risk factors for shoulder pain in the masters swim competition level, and to validate recommended cut points for various tests and measures.

Published: January 2024

Background Plantar fasciitis (PF) results in pain-related disability and excessive healthcare costs. Photobiomodulation therapy (PBMT) has shown promise for decreasing both pain and disability related to PF. Purpose The purpose was to assess the clinical impact of PBMT on pain and function in people with PF. Study Design Prospective, randomized controlled clinical trial Methods A convenience sample of adults with PF were randomly assigned to one of three groups: (1) usual care, (2) usual care plus nine doses of PBMT with 25W output power over three weeks, or (3) usual care plus nine doses of PBMT with 10W output power over three weeks. Both 10W and 25W PBMT participants received the same total dose (10J/cm2) by utilizing a simple area equation. Pain (with Defense and Veterans Pain Rating Scale) and function (by Foot and Ankle Ability Measure) were measured at baseline, weeks 3, and 6 for all groups, and at 13 and 26 weeks for PBMT groups. Results PBMT groups experienced a reduction in pain over the first three weeks (from an average of 4.5 to 2.8) after which their pain levels remained mostly constant, while the UC group experienced a smaller reduction in pain (from an average of 4 to 3.8). The effects on pain were not different between PBMT groups. PBMT in both treatment groups also improved function more than the UC group, again with the improvement occurring within the first three weeks. Conclusions Pain and function improved during the three weeks of PBMT plus UC and remained stable over the following three weeks. Improvements sustained through six months in the PBMT plus UC groups.

Authors: Cattaneo Marco , Ramponi Carlo , Thorborg Kristian 
Published: January 2024

BACKGROUND Professional male ice hockey is characterized by a congested in-season match schedule and by different scenarios where the whole body is exposed to great internal and external forces. Consequently, injuries occur from head to toe. However, there is a lack of data synthesis regarding the injury incidence and profile in this population. PURPOSE The aim of this study was to conduct a systematic review to quantify the injury incidence rates in professional male ice hockey. STUDY DESIGN Systematic Review METHODS The electronic databases PubMed, CINAHL, Web of Science, ProQuest-Sport medicine & Education Index, and Pro-Quest Dissertation and Thesis were searched utilizing terms related to ice hockey and injuries. Studies were included if they provided the incidence of injury in professional male hockey players and reported injuries in terms of time lost. The modified Newcastle Ottawa Scale for cohort studies and the Strengthening the Reporting of Observational Studies in Epidemiology - Sports Injury and Illness Surveillance Statement were used to assess the methodological quality of the studies. RESULTS Eleven studies were included in the review. Match injury incidence ranged from 38 to 88.6 injuries/1000 hours of exposure, whereas training injury incidence varied from 0.4 to 2.6 injuries/1000 hours of exposure. Injuries of traumatic origin accounted for 76% to 96.6% of all injuries, with contusions and lacerations being the most common. Severe injuries accounted for 7.8% - 20% of all injuries. The lower extremities were the most susceptible to injury, comprising 27% to 53.7% of all reported injuries. CONCLUSION Professional male ice hockey players are exposed to a substantial risk of injury during competitions, with lower extremities being the most commonly affected body part. The majority of injuries are traumatic and severe injuries account for a notable portion of overall injury cases.

Authors: Heick John D , Alkathiry Abdulaziz 
Published: January 2024

Background A concussion is a traumatic brain injury that can result in vestibular and oculomotor dysfunctions. The Head Shake-Sensory Organization Test was developed from the original Sensory Organization Test to measure a subject’s ability to maintain balance while moving their head. Purpose The purpose of this study was to compare the performance of adults with no history of concussion to those with a history of concussion on the Head Shake-Sensory Organization Test to determine if long-standing balance deficits are present after concussion. Study Design Cross-sectional study Methods Subjects with a history of concussion and healthy normal controls completed the Dizziness Handicap Inventory, the Activities-Specific Balance Confidence Scale, the sensory organization test, the head shake SOT, and the Foam Head Shake-Sensory Organization test in a single testing session. Scores were analyzed for differences between the two groups. Results Twenty-five participants (nine patients with history of concussion and 16 healthy controls; mean age, 21.08±4.10 years) completed testing. The equilibrium scores in both groups significantly decreased with more complex tasks. Furthermore, the concussion group had significantly worse equilibrium scores than the control group during the Head Shake (p = 0.007) and Foam Head Shake-Sensory Organization Test (p = 0.002) tasks but not during the Sensory Organization Test task. Conclusion Adding head shake and foam cushion conditions to postural stability tests improves sensitivity in detecting balance deficits in individuals with a concussion. Level of Evidence 3
Sensorimotor Dysfunction Following Anterior Cruciate Ligament Reconstruction- an Afferent Perspective: A Scoping Review
Authors: Vitharana Thilina N , King Enda , Moran Kieran 
Published: January 2024

Background Sensorimotor dysfunction is thought to occur following anterior cruciate ligament (ACL) injury which may have implications on future reinjury risk. Dysfunction has been demonstrated within the efferent component of the sensorimotor system. However, no reviews have examined the two main components of the afferent system: the visual and somatosensory systems. Hypothesis/Purpose This study aimed to report differences in function (central processing and local processing) within the (1) somatosensory and (2) visual systems between individuals following anterior cruciate ligament reconstruction (ACLR) and healthy controls (between-subject). The study also aimed to report differences in function within the two systems between the two limbs of an individual following ACLR (within-subject). Study Design Scoping review Methods A search was conducted in PubMed, SPORTDiscus, CINAHL, Medline and Embase up until September 2021. Level I-IV studies assessing somatosensory and visual systems were included if they compared ACLR limbs to the uninjured contralateral limb (within-subject) or a healthy control limb (between-group). The function of somatosensory and visual systems was assessed across both central processing (processing of information in the central cortex) and local processing (all other assessments outside of central processing of information). Results Seventy studies were identified (52 somatosensory, 18 visual). Studies examining somatosensory central processing demonstrated significant differences; 66% of studies exhibited within-subject differences and 100% of the studies exhibited between-group differences. Studies examining local somatosensory processing had mixed findings; 40% of the ‘joint position sense (JPS)’ and ‘threshold to detect motion (TTDM)’ studies showed significant within-subject differences (JPS=0.8°-3.8° and TTDPM=0.2°-1.4°) and 42% demonstrated significant between-group differences (JPS=0.4°-5° and TTDPM=0.3°-2.8°). Eighty-three percent of visual central processing studies demonstrated significant dysfunction between-groups with no studies assessing within-subject differences. Fifty percent of the studies examining local visual processing demonstrated a significant between-group difference. Conclusion Significant differences in central processing exist within somatosensory and visual systems following ACLR. There is mixed evidence regarding local somatosensory and visual processing. Increased compensation by the visual system and local visual processing dysfunction may occur in conjunction with somatosensory dysfunction.

Authors: Rosero Obando Fredy , Rosero Xavier , Mera Zamir 
Published: January 2024

A vehicle interacts with the road, other vehicles, and traffic control devices in real traffic conditions. The level of traffic influences driving patterns and, consequently, this can affect the vehicle´s fuel efficiency and emissions. This study aims to develop engine maps of fuel consumption and CO2 emissions for a light vehicle operating under real traffic conditions. A representative passenger vehicle of the Ecuadorian vehicle fleet, powered by gasoline, was selected for the experimental campaign that was developed on a test route designed according to real driving emission (RDE) regulation. An on-board diagnostic (OBD) device was used for recording in real-time engine and vehicle operating parameters. Moreover, CO2 emissions were estimated using the fuel rate registered from the OBD system of the vehicle This study proposed a novel methodology for developing two-dimensional contour engine maps based on OBD data. The result showed that the vehicle engine operated in real traffic conditions with a brake thermal efficiency (BTE) of 27%, a brake-specific fuel consumption (BSFC) of 275 g/kWh, and a carbon dioxide (CO2) energy-emission factor of 716 g/kWh. In terms of distance, the CO2 emission factor for the tested vehicle was approximately 190 g/km. Overall, this study demonstrates that the OBD approach is a potential method to be used to assess the fuel consumption and emissions of a vehicle operating under real-world traffic conditions, especially in Latin American countries, where portable emission measurement systems (PEMS) are not readily available.

This investigation was a case of study in the powder detergent packaging line and aimed to reduce all those wastes that do not add value to the product, increasing the cost of production. Reducing or eliminating waste within the manufacturing industry becomes necessary for sustainable businesses over time and keeps generating development. To achieve it, the Lean Six Sigma DMAIC methodology was implemented in a detergent powder packaging line, to identify the problems that afflicted and made production more expensive. By using quality tools (such as Pareto and Ishikawa diagrams, 5S application, Poka-Yokes, SMED, training personnel, and standardizing processes) it was possible to reduce unproductive times. Energy consumption was reduced by up to 20 %, also efficiency and machine availability increased by 10.98 % and 7.32 %, respectively. The general performance of the line increased by 15.16 %, which translates into significant monthly savings of USD 71 442.05. By applying these improvement techniques, the most significant efficiency was registered in 1 kg packages, going from 47 % to 89 %, approximately. To maintain this productivity and even to perfect it, it is necessary to hire specialized personnel who know the production processes and industrial operations.
