There is no research to assess how objectively measured training loads throughout a season influence aerobic capacity. The following study was a retrospective analysis of an NCAA Division I women\u2019s basketball team throughout a 5-month (23-week) competitive season.

For example, TMS has been commonly used to investigate adaptations to exercise, rehabilitation, and neurological impairments. However, TMS data can be highly variable, making it challenging to report consistent findings. One factor that has received little attention in the literature is whether the timing between multiple TMS pulses (i.e., interpulse interval) influences outcomes, particularly for leg muscles. Our manuscript published in Brain Connectivity examined whether interpulse interval duration influences corticospinal excitability, a common TMS metric. Seventeen college-aged males and females participated in a single laboratory visit, during which 25 single TMS pulses were delivered to the motor cortex with interpulse intervals of 5, 10, 15, and 20 seconds. Our findings show that interpulse interval duration has little influence on corticospinal excitability for the knee extensors during active contractions. In our publication, we discuss the implications, strengths, and limitations of our findings.

This work largely focuses on adults. However, there is an inverse relationship between cellphone use and age. Because their cellphone use may be different from adults, understanding these relationships in younger individuals is warranted.\r\nMethods: High school students (N = 17) completed an online survey consisting of validated items assessing self-reported cellphone use, physical activity, sedentary behavior, anxiety, and grade point average. Correlation analyses were then performed assessing the relationships between cell phone use to all other variables. \r\nResults: There were large, significant effect sizes (r \u2265 -0.58, p \u2264 0.04) for negative correlations between cellphone use and vigorous and total physical activity. There was also a moderate effect size (r = -0.39; r = 0.46) for a negative relationship between cellphone use and mild physical activity and a positive correlation between cellphone use and anxiety, respectively. Cellphone use was not related to the remaining variables.\r\nConclusions: In this preliminary study of high school students, greater cellphone use was associated with greater anxiety, which supports prior research in adults.

In a previous prospective descriptive assessment of in situ running biomechanics in collegiate cross-country athletes, a subset of athletes developed repetitive stress lower extremity injuries during study participation. The purpose of this preliminary, observational study was to assess sensor-derived biomechanics in the several days leading up to injury (n = 8; 4 female, 4 male) compared with runners who remained healthy (n = 14; 9 female, 5 male) over a single cross-country season.\r\n\r\nMethods \r\nWearable sensors were used to collect running biomechanics during two weekly runs, and surveys were used to capture wellness and injury. Individual z scores of biomechanical measures were assessed for runners who developed injuries and compared against healthy male and female z scores.\r\n\r\nResults \r\nOf the eight injuries, four were categorized as bone stress injuries (three female, one male), and four as soft tissue injuries (one female, three male). Bone injury cases had increased contact time, loading, and pronation, and decreased cadence and stride length preceding injury. Hamstring injury cases (n = 2) had increased stride length, whereas foot and ankle soft tissue injuries had increased pronation velocity and decreased shock and braking.\r\n\r\nConclusions \r\nThis assessment of injury cases illuminates several biomechanical patterns associated with running-related injury development.

Twenty healthy men received a nutritional supplement or not and 10 blood samples were collected throughout three study phases: baseline data collection (BDC), head-down tilt (HDT) bed rest, and reambulation (R). We measured gene expression through RNA sequencing of leukocytes, applied generalized linear models to assess differential expression followed by enrichment analysis to identify temporal changes (model 1) and to measure the impact of a nutritional supplement (model 2). Baseline transcriptomes included 14,624 protein-coding transcripts, which showed high interindividual correlations (0.89\u00b10.03). We identified 2,415 differentially expressed protein-coding transcripts grouping into six clusters (C1-C6) displaying either a decrease-then-increase (C3 and C5) or an increase-then-decrease (C1,C2,C6) patterns at phase transitions. All six clusters converged toward average expression at HDT30 and HDT60. Gene ontology terms at baseline related to immune functions while in bed rest and reambulation related to multisystem organ processes. The temporal profiles of leukocytes\u2019 transcriptomes emphasize dynamic gene expression changes occurring during and after bed rest. Current findings can guide future work to identify gene markers responsive to the microgravity environments.","duration":null,"file_audio":null,"file_video":"1681838732252dUoVo.mp4","compressed":1,"slug":"the-characteristic-response-of-the-human-leukocyte-transcriptome-to-60-days-of-bed-rest-and-to-reambulation-4zXyLE1Hy","date_published_readable":"April 18, 2023","author":"Daniel Stratis","author_slug":"daniel-stratis-4zXyLE1JL","keywords":[{"name":"bed rest","slug":"bed-rest-4zXyLE1Js"},{"name":"reambulation","slug":"reambulation-4zXyLE1Jt"},{"name":"transcriptome","slug":"transcriptome-4zXyLE1Ju"},{"name":"leukocytes","slug":"leukocytes-4zXyLE1Jv"},{"name":"immunity genes","slug":"immunity-genes-4zXyLE1Jw"},{"name":"cellular stress","slug":"cellular-stress-4zXyLE1Jx"}],"disciplines":[]},{"ID":57,"status":40,"date_created":"2023-03-11 17:11:12","article_ID":57,"audience_type":0,"stats_view":498,"stats_like":1,"stats_save":0,"stats_play":0,"title":"Exploring Training Strategies to Optimize Court Performance in Older Pickleball Athletes","abstract":"Pickleball is one of the fastest growing racket sports in the United States due to its high\r\nsocial engagement and ability to facilitate physical and emotional well-being in persons\r\nacross the lifespan.

This may be part of the adaption process to such diets, and non-pathological.
