This article proposes a close reading of Rivers Solomon’s 2019 novella The Deep, a recent eco-story about water, memory, and survival. Solomon’s work is inspired by a song called “The Deep” from experimental hip-hop group clipping, a dark science fiction tale about the underwater-dwelling descendants of African women thrown off slave ships during the Middle Passage. This imaginative alternate history, or counter-mythology, was invented by the Detroit techno band Drexciya, which, in a series of releases between 1992 and 2002, tells us the story of an underwater realm in the mid-Atlantic, where merpeople and their descendants establish a utopian society in the sea, free from the war and racism on the surface. My analysis uses Saidiya Hartman’s “critical fabulation” to make productive sense of the gaps in the archive of trans-Atlantic slavery that silence the voices of enslaved women, listening to the voices of water to imagine not only what was but also what could be. Moreover, this article examines The Deep through a trajectory that moves from the ocean as a space that reproduces death only to the ocean as a generative force for posthuman and multispecies kinship. Using Black hydrocriticism, hydrofeminism, and econarratology, I will argue that this transition is made possible by the “despatialization” of the ocean—a concept introduced by Erin James—where the ocean is conceived not as a fixed or stable environment, but as a space in constant flux, defying stability, and the subsequent immersion in its waters.

Augmenting the author’s prior research on lyrical code-switching, as presented in Picone, “Artistic Codemixing”, published in 2002, various conceptual frameworks are made explicit, namely the enlistment of multimodal and intertextual approaches for their methodological usefulness in analyzing and interpreting message-making that incorporates lyrical code-switching as one of its components. Conceived as a bipolarity, the rooted (or local) and the transcendent (or global), each having advantages in the negotiation of identity, is also applied to the analysis. New departures include the introduction of the notion of “curated lyrical code-switching” for the purpose of analyzing songs in which multiple performers are assigned lyrics in different languages, as a function of their respective proficiencies, as curated by the person or persons having authorial agency and taking stock of the social semiotics relevant to the anticipated audience. Moving beyond the negotiation of the identity of the code-switching composer or performer, in another new departure, attention is paid to the musical identity of the listener. As a reflection of the breadth of lyrical code-switching, a rich assortment of examples draws from the musical art of Beyoncé, Jon Batiste, Stromae, Shakira, BTS, NewJeans, Indigenous songsmiths, Cajun songsmiths, Latin Pop and Hip-Hop artists, songs composed for international sports events, and other sources.

Background and Objectives: Patellofemoral pain (PFP) is frequent in the young and active population. The effect of muscle strength in the lower extremities after aerobic activity in patients with this condition has yet to be detailed. Our objective was to determine if patients with PFP show alterations in lower extremity muscle strength measurements after performing a session of ten minutes of aerobic activity on a treadmill compared to people without patellofemoral pain. Materials and Methods: We conducted a prospective experimental study with a stratified, non-randomized, and non-blinded population sample with group matching, including an experimental group with PFP and a control group with no pain. Subjects completed self-reported functional questionnaires (IKDC, Kujala, KOOS, SF-12), underwent radiographic studies, and were evaluated by measuring the strength of hip and knee muscles and the Single-Leg Triple-Hop (SLTH) test before and after ten minutes of exercise on a treadmill. Results: Seventeen subjects diagnosed with PFP and seventeen control subjects were evaluated. Both groups were homogeneous and had no significant differences in the demographic variables. A wider sulcus angle at 30° (136.8 ± 3.8° vs. 132.5 ± 5.6°, p = 0.0140), a decrease strength post-exercise in the hip abductor (37.9 ± 7.1 N⋅m vs. 45.6 ± 7.7 N⋅m, p < 0.05) and knee extensor (36.0 ± 9.1 N⋅m vs. 47.7 ± 14.0 N⋅m, p < 0.05), and a shorter distance in the SLTH test (337.9 ± 74.9 cm vs. 438.6 ± 65.8 cm, p < 0.01) was recorded in subjects with patellofemoral pain. Conclusions: Subjects with PFP had an overall lower strength of hip and knee muscles, showing significant differences in the hip abductors and knee extensors between people with PFP and healthy matched controls after aerobic exercise.

Objective: To evaluate how access to an office-based laboratory (OBL) and ambulatory surgery center (ASC) impacted vascular care during the Coronavirus Disease 2019 (COVID-19) pandemic. Methods: Vascular procedures performed by our group during the 6-week period before COVID-19 restrictions (group 1) and in the first 6-week period during the COVID-19 restrictions (group 2) were reviewed. The number of procedures performed was categorized as hospital inpatient (HIP), hospital outpatient (HOP), OBL, ASC, and vein center (VC). The procedures were also grouped by type: aneurysm (AAA), carotid (CAR), peripheral arterial disease (PAD), amputation/wound care (AMP), vascular access (VA), deep vein thrombosis (DVT), and venous reflux (CVI). The number of healthcare provider contact points for each patient undergoing care at the HOP, OBL, and ASC were also collected and compared between groups 1 and 2. Differences between groups were determined using the two-way ANOVA. Results: There were no statistically significant differences between groups 1 and 2 for procedure location or type of procedure (p > 0.05). Patient contact with healthcare providers decreased between groups 1 and 2 for ambulatory care. However, projecting the number of contacts for patients in group 2 if they had to have ambulatory care in the HOP setting (913) compared to contacts in the OBL and ASC setting (588) was statistically significant (p < 0.05). No patient or staff member at the OBL or ASC developed COVID-19 infection because of the care received at these venues. Conclusions: The ability to provide essential care for patients in an ambulatory environment was enhanced using our OBL and ASC without compromising safety, efficacy, or transmission of the virus to patients or staff during the height of the COVID-19 pandemic and limited their contact with healthcare workers and therefore reduced the consumption of personal protective equipment by healthcare personnel.

As a significant form of physical expression, dance demands ongoing training for skill enhancement, particularly in expressiveness. However, such training often faces restrictions related to location and time. Moreover, the evaluation of dance performance tends to be subjective, which necessitates the development of effective training methods and objective evaluation techniques. In this research, we introduce a self-training system for dance that employs VR technology to create an immersive training environment that facilitates a comprehensive understanding of three-dimensional dance movements. Furthermore, the system incorporates markerless motion capture technology to accurately record dancers’ movements in real time and translate them into the VR avatar. Additionally, the use of deep learning enables multi-perspective dance performance assessment, providing feedback to users to aid their repetitive practice. To enable deep learning-based dance evaluations, we established a dataset that incorporates data from beginner-level dances along with expert evaluations of those dances. This dataset was specifically curated for practitioners in a dance studio setting by using a total of four cameras to record dances. Expert annotations were obtained from various perspectives to provide a comprehensive evaluation. This study also proposes three unique automatic evaluation models. A comparative analysis of the models, particularly contrastive learning (and autoencoder)-based expression learning and a reference-guided model (where a model dancer’s performance serves as a reference), revealed that the reference-guided model achieved superior accuracy. The proposed method was able to predict dance performance ratings with an accuracy of approximately ±1 point on a 10-point scale, compared to ratings by professional coaches. Our findings open up novel possibilities for future dance training and evaluation systems. Full article

Background and Objectives: Fibromyalgia syndrome (FM) is a chronic pain disorder that is ranked as one of the four most common rheumatological diseases in the world. This study aims to investigate the effects of an eight-week mat Pilates and electro-muscle stimulation (EMS) with combined mat Pilates exercises on pain, depression, anxiety, and strength in sedentary women. Methods: This study is a single-blind randomized controlled trial. A total of 30 sedentary female patients (Pilates (n = 15), EMS (n = 15)) diagnosed with FM were included in the study. The patients were subjected to Beck Depression (BDIs) and Anxiety Inventories (BAIs); a Fibromyalgia Impact Questionnaire (FIQ); five different Single-Leg Hop Tests (SLHTs); modified push-up (MPU), Handgrip Strength (HGS), Deep Squat (DSQ), V-Sit Flexor, bent-arm hang (BA), sit-up and Biering-Sørensen tests; and anthropometric tests before and after the 8-week exercise program. Results: The eight weeks of mat Pilates exercises combined with mat Pilates and EMS revealed significant results (p < 0.05) in anthropometric data (abdomen, lower abdomen, hips) (p < 0.05) except for the results of chest circumference measurements (p > 0.05). In addition, there were statistically significant positive results in BDIs, BAIs, FIQs, lower extremity (all SLHTs and DSQ), upper extremity (MPU, HGS, BA), and core (V-SIT, sit-up, Biering-Sørensen test) strength test findings (p < 0.05). Conclusions: Combining the mat Pilates exercises with EMS is an effective and reliable method to improve the pain, anxiety, depression, and strength of female patients diagnosed with FM.

The calorie and taste choices of food have been shown to be related to the external environment, including music. Previous studies have mostly focused on manipulating basic auditory parameters, with few scholars exploring the impact of complex musical parameters on food selection. This study explored the effects of different kinds of music (classical, rock, jazz, and hip-hop) on food liking based on the calories (high and low) and taste (sweet and salty) using event-related potentials (ERPs). Twenty-four participants (8 males, 16 females) were recruited from Southwest University, China to participate in the food liking task using a Likert seven-point rating and simultaneously recording EEG signals (N2, P2, N3, and LPC). This study used repeated-measures analyses of covariances and found that the score of the high-calorie foods was greater than that of the low-calorie foods. Additionally, results revealed that the score in classical music was greatest for sweet foods, while there was no difference among music kinds in the salty foods. The ERP results showed that P2 amplitudes were greater for sweet foods than those for the salty foods. N2 amplitudes for the salty foods were greater than those for the sweet foods during rock music; in addition, N2 amplitudes during hip-hop music were greatest for sweet foods. However, N2 amplitudes during rock music were the greatest for salty foods. The results also revealed that N2 amplitudes during hip-hop music were greater than those during jazz music. This study provides unique operational insights for businesses. Full article

This study aimed to determine the minimum number of repetitions for a high reliability of movement timing in fundamental physical fitness exercises using inertial sensors. Fifteen young men and fifteen women performed eight exercises (two-leg hop, forward lunge, squat, sit-up, shoulder abduction, hip abduction, back extension, and push-up) (preferred tempo, 3 trials, 20 repetitions per trial). The movement timing (cycle of movement in seconds and its phases in seconds and %tcycle) was tested for intra- and inter-trial reliability (SPSS 28.0, p ≤ 0.05). Just two repetitions were adequate for excellent intra- and inter-trial relative reliability (ICCs ≥ 0.75, isolated exceptions only for durations expressed as %tcycle, in only three out of the eight exercises: hip abduction, back extension, and push-up), as well as for high absolute intra- and inter-trial reliability (average SEM% at 5.9%, respectively, and 6.8% and average MDC95% at 13.7% and 15.9%, respectively, which was consistently higher than the upper boundary limit of SEM%, and a rather low CV% ranging from 1.5% to 4.9% and averaging at 3.1%). A total of four repetitions, excluding the initial and the final one, appears adequate for high overall reliability of movement timing in the eight physical fitness exercises examined. Full article

Little is known about the inflammatory potential of diet and its relation to bone health. This cross-sectional study examined the association between the inflammatory potential of diet and bone-related outcomes in midwestern, post-menopausal women enrolled in the Heartland Osteoporosis Prevention Study (HOPS) randomized controlled trial. Dietary intake from the HOPS cohort was used to calculate Dietary Inflammatory Index (DII^®) scores, which were energy-adjusted (E-DII^TM) and analyzed by quartile. The association between E-DII and lumbar and hip bone mineral density (BMD) and lumbar trabecular bone scores (TBS; bone structure) was assessed using ANCOVA, with pairwise comparison to adjust for relevant confounders (age, education, race/ethnicity, smoking history, family history of osteoporosis/osteopenia, BMI, physical activity, and calcium intake). The cohort included 272 women, who were predominately white (89%), educated (78% with college degree or higher), with a mean BMI of 27 kg/m², age of 55 years, and E-DII score of −2.0 ± 1.9 (more anti-inflammatory). After adjustment, E-DII score was not significantly associated with lumbar spine BMD (p = 0.53), hip BMD (p = 0.29), or TBS at any lumbar location (p > 0.05). Future studies should examine the longitudinal impact of E-DII scores and bone health in larger, more diverse cohorts. Full article

Time-motion analysis has been used to quantify the external load of competition and as a strategy to prevent injuries. The objectives of this study were to determine the external load of competition in breaking, using time-motion analysis, and to establish a battle model to help determine training load and prevent injuries. Using observational methodology, we analysed all the battles of 56 b-boys and 56 b-girls who participated in the Red Bull BC One from 2018 to 2021 (n = 112). To obtain the results we used different analysis techniques. The significance level established was ρ ≤ 0.05. The results show that the time and sequence values have increased in recent years. The total battle time reaches 195 s for bboys and 170 s for bgirls. Men show greater strength and explosiveness, with higher values in total time and sequentiality, using more powermove. Women have higher split time values, showing greater endurance in the movements and using more footwork. The first two rounds have the longest duration for both sexes and the most used categories are also the most injurious in this discipline. Women use less powermove than men and have a lower injury rate. With these results, breaking professionals will be able to elaborate adequate training for their athletes. We conclude that there are significant differences between sexes when it comes to dancing, diminishing as the tournament progresses. We propose a model of temporal and sequential structure individualised by sex. The most damaging elements of breaking (powermove and footwork) should be taken into account when analysing the results and preparing the athletes. Full article

The purpose of this study was to investigate associations between peak magnitudes of raw acceleration (g) from wrist- and hip-worn accelerometers and ground reaction force (GRF) variables in a large sample of children and adolescents. A total of 269 participants (127 boys, 142 girls; age: 12.3 ± 2.0 yr) performed walking, running, jumping (<5 cm; >5 cm) and single-leg hopping on a force plate. A GENEActiv accelerometer was worn on the left wrist, and an Actigraph GT3X+ was worn on the right wrist and hip throughout. Mixed-effects linear regression was used to assess the relationships between peak magnitudes of raw acceleration and loading. Raw acceleration from both wrist and hip-worn accelerometers was strongly and significantly associated with loading (all p’s < 0.05). Body mass and maturity status (pre/post-PHV) were also significantly associated with loading, whereas age, sex and height were not identified as significant predictors. The final models for the GENEActiv wrist, Actigraph wrist and Actigraph hip explained 81.1%, 81.9% and 79.9% of the variation in loading, respectively. This study demonstrates that wrist- and hip-worn accelerometers that output raw acceleration are appropriate for use to monitor the loading exerted on the skeleton and are able to detect short bursts of high-intensity activity that are pertinent to bone health.

This study aimed to identify football players at high risk (HR) for anterior cruciate ligament (ACL) injury via a four-test battery and assess possible factors affecting classification. Ninety-one professional and semi-professional male athletes participated in a field-based pre-season screening. The cut-off points of the test battery were 10% acknowledged inter-limb asymmetry limit for quadriceps and hamstring isometric strength and single-leg triple hop for distance, in addition to the upper limit of 6 errors in the landing error scoring system (LESS). Additional assessment of hip adductors and core stability completed the global functional profile of the players. Sixty-one players were identified as HR and thirty as low-risk (LR) for ACL injury. Discriminant analysis showed that the proposed test battery classified accurately 78.0% of them, with 91.8 sensitivity and 61.9% specificity. Only four misclassified players in the LR group were at risk of inadequate treatment. All participants were considered healthy, and history of a previously rehabilitated injury did not interfere with the results. LESS seems to be the best predictor for injury-risk grouping. Prone bridge time was also a whole-body variable discriminating between groups. The proposed test battery provides a promising option for field-based pre-season ACL risk assessment of football players and needs to be studied prospectively. Full article

Futsal is one of the most harmful sports due to its great physical demands. The asymmetries have been proposed as one of the most important risk factors of suffering an injury. However, no study has analysed the relationship between neuromuscular assessment and its implication on the likelihood of suffering injuries comparing male and female players. The purpose of the study was to analyse the physical fitness differences between elite futsal players (both male and female) who suffered an injury in the following four months after being evaluated with those who did not suffer the injuries. Twenty-six and twenty-two male and female elite futsal players were recruited from four different teams and underwent an evaluation of different neuromuscular assessments (isometric hip abduction and adduction peak torque, flexion-rotation trunk test, hop test, countermovement jump (CMJ), drop vertical jump (DVJ), leg stiffness, 15 m sprint, Y-balance test, and Illinois test) that have been considered potential sport-related injury risk factors during the pre-season. Statistical analysis only showed differences between injured and non-injured players in isometric hip adduction strength and unilateral ratio for the non-dominant leg (p < 0.05). Neuromuscular performance scores showed significant differences (p < 0.001) between male and female futsal players in several variables (hip abduction non-dominant leg, hops, CMJ, DVJ, leg stiffness, sprint, and Illinois test) but not in ratio or asymmetry. Isometric hip adduction and abduction–adduction unilateral ratio deficits for the non-dominant leg might be an important factor toward suffering an injury. Male and female futsal players showed different neuromuscular performances and consequently different training programs should be implemented for them. Full article

Kendrick Lamar’s 2022 track “We Cry Together” is, if nothing else, a masterful piece of wordplay and rhythm. Lamar manages to create a lyrical conversation that sounds both dialectical and diametric. Both the song and album are a definitive break from his earlier tenor that struck a mass appeal. A private conversation between two people, “We Cry Together”, insofar as it captures the intimate interiority of a couple, is also a break within the album itself. Textual renderings of Black performances cut away in ways similar to Lamar’s song or the soloist in a jazz ensemble, their breaks signifying sound. Invoking as aural praxis the language of jazz musicology and Black lyrical theory of Fred Moten, this article closely reads chapter four in George Lamming’s In the Castle of My Skin as one such special representation of textual aurality. First, it identifies multiple manifestations of “the break” before probing the deeply conflicted concept of Black noise as the racialized, resistant, resilient, and resonant octave of radical Black performance. A lyrical improvisation of a Black noise defiant in its indeterminacy, Ma and Pa’s duet cuts away from Castle’s polyphonic ensemble, creating the break within a break, within a break. Lingering in the cut, listening as Fred Moten, Douglas Kearney, Ren Ellis Neyra, and Zadie Smith encourage, the article arrives at a euphonic reproduction as induction into a legacy of synesthetic, lyrical, radical Black noise.

Variation during practice is widely accepted to be advantageous for motor learning and is, therefore, a valuable strategy to effectively reduce high-risk landing mechanics and prevent primary anterior cruciate ligament (ACL) injury. Few attempts have examined the specific effects of variable training in athletes who have undergone ACL reconstruction. Thereby, it is still unclear to what extent the variations in different sensor areas lead to different effects. Accordingly, we compared the effects of versatile movement variations (DL) with variations of movements with emphasis on disrupting visual information (VMT) in athletes who had undergone ACL reconstruction. Forty-five interceptive sports athletes after ACL reconstruction were randomly allocated to a DL group (n = 15), VT group (n = 15), or control group (n = 15). The primary outcome was functional performance (Triple Hop Test). The secondary outcomes included dynamic balance (Star Excursion Balance Test (SEBT)), biomechanics during single-leg drop-landing task hip flexion (HF), knee flexion (KF), ankle dorsiflexion (AD), knee valgus (KV), and vertical ground reaction force (VGRF), and kinesiophobia (Tampa Scale of Kinesiophobia (TSK)) assessed before and after the 8 weeks of interventions. Data were analyzed by means of 3 × 2 repeated measures ANOVA followed by post hoc comparison (Bonferroni) at the significance level of p ≤ 0.05. Significant group × time interaction effects, main effect of time, and main effect of group were found for the triple hop test and all eight directions, SEBT, HF, KF, AD, KV, VGRF, and TSK. There was no significant main effect of group in the HF and triple hop test. Additionally, significant differences in the triple hop test and the seven directions of SEBT, HF, KF, KV, VGRF, and TSK were found between the control group and the DL and VMT groups. Between group differences in AD and the medial direction of SEBT were not significant. Additionally, there were no significant differences between VMT and the control group in the triple hop test and HF variables. Both motor learning (DL and VMT) programs improved outcomes in patients after ACL reconstruction. The findings suggest that DL and VMT training programs lead to comparable improvements in rehabilitation. Full article
