Investigating Turf Burn Videos on TikTok: Observational Study (Preprint)

BACKGROUND Due to the increased use of artificial turf, turf burn has become a common sports injury caused by exposed skin sliding on artificial turf. Health complications such as MRSA outbreaks, sepsis, and pneumonia have been linked to untreated turf burns, and many athletes have been turning to social media for advice and companionship regarding their sports injuries. OBJECTIVE The goal of the study is to categorize and quantitatively assess the percentage of turf burn posts on TikTok based on the creator, content, and the athlete’s experience. With this data, we not only investigate if there is room for health care professionals to assist in the distribution of evidence-based health education to athletes to counteract misinformation, but also investigate if there is a potential audience of athletes on TikTok who have the potential to develop problematic responses to their injuries. METHODS Using the Discover page on TikTok, we searched for the word “turf burn” on October 17, 2021. 100 videos were used. Videos were categorized and analyzed by the creator, content, and experience of the athlete. Likes and comments were recorded. RESULTS Most of the videos (98/100, 98.0%) were created by athletes while only a small fraction of videos (2/100, 2.0%) were created by health-care professionals. Content wise, most of the videos (67/100, 67.0%) displayed the turf burn. A small amount of videos (15/100, 15.0%) showed the incident when the turf burn was acquired while nearly a quarter of the videos (23/100, 23.0%) demonstrated treatment/prevention of turf burns. Out of 23 treatment/prevention videos, a minority of the videos (4/23, 17.4%) showed accurate treatment of turf burns while most of the videos (19/23, 82.6%) showed inaccurate treatment. The smallest amount of videos (2/100, 2.0%) were about education of turf burns. Most of the athlete videos (56/98, 57.1%) depicted negative experiences the patient had with turf burn. Some of the videos (37/98, 37.8%) depicted neutral experiences while the smallest amount (5/98, 5.1%) depicted positive experiences. CONCLUSIONS Our observational study suggests that there is a potential audience of athletes on TikTok who could develop problematic responses to their sports injuries such as turf burn, as most of the people who post videos are athletes and many of the posts demonstrate a negative experience associated with the turf burn. TikTok is a growing social media platform that should be studied to see if it can be used to create a social support group for injured athletes to prevent the progression of their negative emotional responses into problematic responses. Physicians should also have a role in establishing their social media presence on TikTok and offer evidence-based advice to athletes while disproving misinformation that is present on TikTok.

The effect of different playing surfaces on soccer skill performance

Football (soccer) is traditionally played on natural grass but artificial surfaces are becoming an increasing popular alternative. Understanding how different surfaces affect a player's skill performance has not been examined. This study sought to compare soccer skill performance, using a validated test, on natural grass, third generation (3G) artificial turf, and indoor sprung wooden floor. Following familiarisation, 14 male players (12.7 ± 0.5 years-old, with 6.21 years playing experience) performed the Loughborough Soccer Passing Test (LSPT) on three different surfaces in the following order: indoor, grass and artificial turf. Players were given two practise attempts before the best of two trials were recorded. Movement time was faster on artificial turf (45.1 ± 1.3 s) than natural grass (46.2 ± 1.8 s; p = 0.045), but there was no difference in overall LSPT performance between grass (54.1 ± 4.2 s) and artificial turf (54.0 ± 4.7 s; p = 0.92). Overall LSPT performance was better on indoor surface (50.9 ± 4.6 s) than grass (p = 0.02) and artificial turf (p = 0.02) due to reduced penalty time on the indoor surface (5.5 ± 3.3 s) than grass (7.9 ± 2.9 s; p = 0.001) and artificial turf (8.9 ± 3.9 s; p = 0.003). There is no difference in soccer skill performance between grass and 3G artificial turf. Skill performance on an indoor surface was ∼6% better than both grass and 3G artificial turf due to better ball control and/or accuracy of passing. Our findings will enable comparison of studies using the LSPT on indoor and outdoor (grass or artificial) surfaces.

Design of a radiant panel test at reduced scale for the high throughput development of artificial turf structures

Artificial turf structures are increasingly used in closed areas and have to comply with the European fire standard for building products (EN ISO 13501-1). The main test to evaluate the fire performance of flooring products is the EN ISO 9239-1 radiant panel test. The test principle is to determine the critical heat flux of floorings exposed to a forced ignition and a specific heat flux profile. As large amounts of material are needed to perform the test, the development of a radiant panel test at reduced scale was considered. The experimental design methodology was implemented to mimic the heat flux profile. The fire performance of artificial turf structures was evaluated at both scales and the results were compared. The burnt lengths of the specimens and thus the critical heat flux are similar for both scales. Thus, the downscaled device could advantageously be used for high throughput development of artificial turf structures.

UPAYA PEMERINTAH DAERAH DALAM MEMBANGUN KESADARAN PENGUNJUNG TAMAN ALUN-ALUN CIANJUR UNTUK MENERAPKAN BUDAYA KEBERSIHAN, KEINDAHAN, KEAMANAN, KETERTIBAN, DAN KENYAMANAN (K5)

ABSTRAKPenelitian ini bertujuan untuk mengetahui upaya Pemerintah Daerah Kabupaten Cianjur dalam membangun kesadaran pengunjung taman alun-alun Cianjur untuk menerapkan budaya Kebersihan, Keindahan, Keamanan, Ketertiban, dan Kenyamanan (K5). Penelitian ini menggunakan pendekatan kualitatif dengan teknik pengumpulan data menggunakan observasi, wawancara dan dokumentasi serta teknik sampling menggunakan snowball sampling. Teknis analisis data dengan Model Miles dan Huberman. Teori yang digunakan peneliti adalah Kurt Lewin dalam Saefullah dan Rusdiana (2016:4). Hasil penelitian ini menunjukan bahwa dalam upaya membangun kesadaran pengunjung untuk berbudaya K5 Pemerintah Daerah telah melakukan: (1) Kebersihan, yaitu dengan menyediakan tempat sampah diberbagai spot yang ada, (2) Keindahan, yaitu sudah memfokuskan rumput sintetis sebagai daya tarik pengunjung berkunjung dan spot yang lain sebagai penunjang, (3) Keamanan, yaitu sudah menyediakan pos penjagaan dan menugaskan SATPOL PP untuk berkeliling disetiap spot di Taman Alun-Alun Cianjur telah memadai, (4) Ketertiban, aturan yang telah disediakan melalui plang/papan pengumuman yang ada sebagian pengunjung telah mengetahui dari sosial media, (5) Kenyamanan, sudah memperbanyak penanaman pohon dikhususkan untuk saat ini daerah rumput sintetis. Dengan demikian dapat diketahui bahwa upaya Pemerintah Daerah dalam membangun kesadaran pengunjung sudah memadai, meskipun masih banyak pengunjung yang masih kurang menyadari akan pentingnya menerapkan K5 di taman alun-alun Cianjur, sehingga dibutuhkan proses sosialisasi dan upaya penindakan bagi mereka yang mengabaikan aspek-aspek K5 tersebut. ABSTRACTThis study aims to determine the efforts of the Regional Government of Cianjur Regency in building awareness of visitors to the Cianjur square park to apply the culture of Cleanliness, Beauty, Security, Order, and Comfort (K5). This study uses a qualitative approach with data collection techniques using observation, interviews and documentation as well as sampling techniques using snowball sampling. Technical data analysis with Miles and Huberman Model. The theory used by the researcher is Kurt Lewin in Saefullah and Rusdiana (2016: 4). The results of this study indicate that in an effort to build visitor awareness for K5 culture, the Regional Government has carried out: (1) Cleanliness, namely by providing trash cans in various existing spots, (2) Beauty, which has focused on synthetic grass as anattraction for visitors to visit and spot others as support, (3) Security, which has provided a guard post and assigned the PP SATPOL to go around every spot in Cianjur Square Park, (4) Orderliness, the rules that have been provided through signposts / bulletin boards that have some visitors already know from social media, (5) Convenience, has increased tree planting specifically for the artificial turf area at this time. Thus it can be seen that the local government's efforts in building visitor awareness are adequate, although there are still many visitors who are still not aware of the importance of implementing K5 in Cianjur square park, so a process of socialization and action is needed for those who ignore these K5 aspects.

Surface-Related High School Football Game Injuries on Pad and No Pad Fields (101)

Objectives: Today’s new generations of artificial turf infill systems are increasingly being installed with lighter weight infill systems, which often incorporate interlocking polypropylene or thermoelastomer pad systems under the fiber-infill layers, reportedly to reduce surface shock, decrease concussions, and enhance shoe: surface stability. At this time, however, the effects of pad systems on high school football trauma during game conditions are unknown. With more than one million athletes playing competitive football, the rise in medical costs, and the increasing popularity of base pads being installed today as an alternative to heavier infill weight systems, this study focused on quantifying the potential influence of this practice on the incidence, mechanisms, and severity of game-related, high school varsity football injuries. Methods: Artificial turf playing fields were divided into two groups based on a pad underlayer or a no pad system. Fifty-eight high schools participated across three states over 7 seasons. Outcomes of interest included injury severity, injury category, primary type of injury, injury mechanism, anatomical location of trauma, type of tissue injured, and elective imaging/surgical procedures. Data were subject to multivariate analyses of variance (MANOVA) and Wilks’ λ criteria using general linear model procedures. Data were expressed as injury incidence rates (IIR) per 10 game season. Results: Of 658 varsity games documented, 260 games were played on fields containing pads, and 398 on no-pad fields, with 795 total injuries reported. MANOVA indicated a significant main effect across pad and no pad playing surfaces by injury severity (F3,791 = 11.436; P < .0001), knee trauma (F9,785 = 2.435; P = .045), injury category (F3,791 = 3.073; P < .0001), primary type of injury (F10,785 = 2.660; P < .0001), injury mechanism (F13,781 = 2.053; P < .001), anatomical location of trauma (F16,778 = 1.592; P < .001), type of tissue injured (F4,790 = 4.485; P < .0001), and elective imaging and surgical procedures (F4,790 = 4.248; P < .002). Post hoc analyses indicated significantly higher ( P < .05) substantial injury [10.3, (95% CI, 10.0-10.5) vs 3.0 (2.5-3.4)], player-to turf trauma [6.5, (95% CI, 5.9-7.1) vs 2.0 (1.6-2.4)], patellofemoral syndrome [1.3, (95% CI, 0.9-1.7) vs 0.3 (0.2-0.5)], neck strain [2.0, (95% CI, 1.5-2.5) vs 0.3 (0.2-0.5)], lower leg strain [3.9, (95% CI, 3.3-4.5) vs 1.1 (0.8-1.4)], and a higher number of lower extremity elective imaging and surgical procedures requested [7.2, (95% CI, 6.7-7.7) vs 3.2 (2.8-3.7)] when competing on artificial turf fields with pads as compared to no pad systems, respectively. In regard to reducing the frequency of concussions, there was no significant difference in concussion rate attributed to turf impact [0.3, (95% CI, 0.2-0.6) vs 0.1 (0.1-0.3)] between pad and no pad fields, respectively. Conclusions: The addition of a pad under an artificial turf surface increases injury rates when compared to non-pad fields across most injury categories. At this time, findings do not support the current trend of installing lightweight padded infill systems at the high school level of play. This is the first longitudinal study to investigate the influence of a pad on sport trauma, when integrated with an artificial turf infill system.

Estimating the Circularity Performance of an Emerging Industrial Symbiosis Network: The Case of Recycled Plastic Fibers in Reinforced Concrete

In recent times, the construction industry has been handling circular economy strategies in order to face the most important challenges in the sector, namely the lack of raw materials and the environmental impacts derived from all the processes linked to the entire supply chain. The industrial symbiosis approach represents an effective strategy to improve the circularity of the construction industry. This study analyses the circularity performance of an emerging industrial symbiosis network derived from the production of a cement mortar reinforced with recycled synthetic fibers coming from artificial turf carpets. From the collection of artificial turf carpets at the end-of-life stage it is possible to recover several materials, leading to potential unusual interactions between industries belonging to different sectors. A suitable indicator, retrieved from the literature, the Industrial Symbiosis Indicator (ISI), has been used to estimate the level of industrial symbiosis associated with increasing materials recirculation inside the network. Four scenarios—ranging from perfect linearity to perfect circularity—representing growing circularity were tested. Findings demonstrate that the development of an effective industrial symbiosis network can contribute to improving the circular approach within the construction sector, reducing environmental and economic pressures.
