The Effect of Varying High-Intensity Interval Training Style Warm-Ups on Hemodynamic, Power, and Flexibility Responses

PURPOSE: The purpose of this study was to examine the effectiveness of high-intensity interval training (HIIT) style warm-up on hemodynamic, power, and flexibility responses. METHODS: Twelve male subjects (age: 24.15 ± 3.1 yr. & weight: 78.78 ± 16.83 kg) completed the study. On the first day, initial screening, anthropometric measures, and familiarization with testing procedures were completed. There were a total of 6 randomized testing sessions (separated by at least 48 hours.). The testing sessions were as follows: 3-min warm-up session with 20 sec work followed by 10 sec (C1), 3-min warm-up session with 30 sec work followed by 10 sec (C2), 5-min warm-up session with 20 sec work followed by 10 sec (C3), 5-min warm-up session with 30 sec work followed by 10 sec (C4), 8-min warm-up session with 20 sec work followed by 10 sec (C5), and 8-min warm-up session with 30 sec work followed by 10 sec (C6). The warm-up sessions included timed interval body weight squats. Hemodynamics (heart rate (HR) and systolic (SBP) and diastolic (DBP) blood pressure), a countermovement jump, and flexibility values were recorded before and after warm-up protocols. RESULTS: There was a significant duration*time interaction for flexibility (pCONCLUSION: The findings of the study indicate that a 3-min duration of HIIT style warm-up may be enough to physically prepare individuals to improve flexibility and vertical jump. In addition, the data also suggests that the required/recommended duration for the warm-up to prepare body may be shortened with HIIT style warm-up. Future studies should compare and contrast the efficacy of varying work to rest ratio of HIIT style warm-up with other warm-up protocols to determine the most effective warm-up protocol

Effects of Different Intensity and Duration of Warm-Up on Hemodynamics, Jump Power, and Flexibility

Tabata protocol (TP), usually consisting of eight to nine bouts of 20-sec of maximal exercise with 10-sec rest, is time-efficient intervention with both aerobic and anaerobic benefits. PURPOSE: This study investigated the effectiveness of different variation of TP as a warm-up procedure. METHODS: Twenty-five healthy subjects (13 females and 12 males) participated in this study. Participants performed 6 randomized exercise sessions separated by at least 48 hours. The exercise sessions involved 3-min (TP3-20:10; TP3-30:10), 5-min (TP5-20:10; TP5-30:10) or 8-min (TP8-20:10; TP8-30:10) consecutive bodyweight squats of either 20-sec workout with 10-sec rest (20:10) or 30-sec workout with 10-sec rest (30:10). Heart rate (HR), blood pressure (BP), thigh skin surface temperature (TT), vertical jump performance (VJ), and flexibility (F) were measured before and after execution of the protocols. Countermovement jump was used to measure VJ and sit-and-reach test was used for measuring F. RESULTS Two-way ANOVA demonstrated significant condition*time interaction (pCONCLUSION: The findings are suggestive of a decrease in F following a higher duration of exercise (TP8-20:10 and TP8-30:10). This may be ascribed to greater accumulation of metabolites (lactic acid, ammonia and hydrogen ion) in the working muscles, which may alter Type III and IV afferent neural activity to increase pain perception. Local tissue acidosis also stimulates bradykinin release, which may contribute to the transmission of nociceptive signals from skeletal muscle. Additionally, a higher duration of exercise may increase cortisol level that decreases the pain threshold level. Therefore, the decreases in flexibility may be explained by one or combination of metabolic, hormonal, and neurobiological changes stimulating the brain to inhibit the muscular response

Barriers to STI Education in Adolescents

The Centers for Disease Control and Prevention (CDC) (2018) reports that 20 million new Sexually Transmitted Infections (STIs) occur annually, and cases continue to rise in certain populations, specifically adolescents between the ages of 15 to 24. Although adolescents make up only a quarter of the population, they account for approximately half of new STI infections every year (Shannon & Klausner, 2018). Several practice recommendations for STI screening and education exist for primary care providers, however many research studies show that clinicians fail to provide the appropriate education and resources to adolescents (Bruener & Mattson, 2018). In this paper, an integrative research review was conducted to identify barriers that primary care providers experience during preventative healthcare visits with adolescents. Interventions that clinicians can utilize in their practice to improve STI education and screening are also identified with the goal to decrease the prevalence of STIs in the adolescent population

Community geography: Toward a disciplinary framework

© The Author(s) 2020. Community geography is a growing subfield that provides a framework for relevant and engaged scholarship. In this paper, we define community geography as a form of research praxis, one that involves academic and public scholars with the goal of co-produced and mutually-beneficial knowledge. Community geography draws from a pragmatist model of inquiry, one that views communities as emergent through a recursive process of problem definition and social action. We situate the growth of community geography programs as rooted in two overlapping but distinct traditions: disciplinary development of participatory methodologies and institutional traditions of community engagement in American higher education. We then trace the historical development of these programs, identifying common themes and outlining several challenges that community geographers should prioritize as this subfield continues to grow

Gene therapy in sickle cell disease: Attitudes and informational needs of patients and caregivers

Background: Sickle cell disease (SCD) is an inherited blood disorder that results in serious morbidity and early mortality. Novel therapies for SCD, most notably genetic therapies (GTs) and HLA-mismatched donor hematopoietic cell transplantation, are in clinical trials. While potentially curative, these interventions are some of the most intensive treatments for SCD and are associated with serious and life-altering side effects, which may manifest several years after treatment. Little is known about knowledge, beliefs, and attitudes of individuals with SCD, or their caregivers, toward existing and these emerging therapies. Methods: Patients with SCD at least 13 years of age (n = 66) and caregivers (n = 38) were surveyed about knowledge, attitudes, and beliefs surrounding treatments for SCD. Results: Only 4.8% felt “extremely knowledgeable” about GT for SCD while the majority (63.4%) reported little knowledge. Overall, health literacy was low among respondents. Most respondents had a neutral attitude regarding the safety of GT for SCD, and whether it was a good treatment for the disorder (56.7% and 58.6%, respectively). Only a few respondents endorsed the idea that GT was “unsafe” or “not a good treatment” (5.8% and 4.8%, respectively). There was an association between increasing knowledge about GT and agreement that it is safe (p =.012) and a good treatment for SCD (p =.031). Conclusions: Given that very few patients with SCD feel knowledgeable about GT and a majority have neutral feelings about the safety and utility of this new approach, culturally appropriate patient-centered education is urgently needed as these treatments get regulatory approval and proceed to the clinic

Composição físico-química de carcaças de bezerros holandeses alimentados após o desaleitamento com silagem de grãos úmidos ou grãos secos de milho ou sorgo Physical and chemical carcasses composition of Holstein calves fed after weaning with high moisture grains silage or dry ground grains of corn or sorghum

Avaliou-se a composição físico-química de carcaças de bezerros após desaleitamento até o abate com silagem de grãos úmidos ou grãos secos de milho ou sorgo para a produção de vitelos de carne rosa. Trinta bezerros holandeses foram distribuídos em delineamento em blocos casualizados, com cinco blocos e seis tratamentos, e alimentados com seis rações com teores similares de proteína (18,5% PB) e de energia (3,2 Mcal EM/kg de MS), formuladas com: milho seco moído (MM); silagem de grãos úmidos de milho (SGUM); sorgo seco com tanino moído (SCTM); silagem de grãos úmidos inteiros de sorgo com tanino (SGUISCT); sorgo seco sem tanino moído; e silagem de grãos úmidos inteiros de sorgo sem tanino (SGUISST). Após o resfriamento, foram tomados nas meias-carcaças esquerdas os cortes da seção H&H para estimativa da composição tecidual da carcaça e os cortes no Longissimus dorsi à altura da 12ª e 13ª costelas para determinação da área de olho-de-lombo (AOL), da espessura de gordura subcutânea (EGS), da força de cisalhamento (FC) e da composição química. Não houve efeito da composição das rações concentradas sobre a composição física e a relação entre tecidos na seção H&H, bem como para AOL, EGS e FC. A ração concentrada SGUM resultou em maiores teores de EE no Longissimus dorsi, mas não diferiu das rações SCTM e SSTM. A ração concentrada SGUM gerou maior deposição de gordura muscular em comparação à MM, no entanto, as rações SGUISCT e SGUISST não aumentaram essa deposição em comparação ao fornecimento dos grãos secos moídos. Todos os alimentos avaliados podem ser usados em rações concentradas para bezerros após o aleitamento, pois não comprometem a composições física e química da carca��a e conferem resultados similares.<br>The physical and chemical carcasses composition of calves fed after weaning until slaughter with high moisture grains silage or dry ground grains of corn or sorghum was evaluated, for production of pink meat veal. Thirty Holstein calves were alloted to a complete randomized blocks experimental design with five blocks and six concentrate rations with similar contents of protein (18.5% CP) and energy (3.2 Mcal ME/kg DM), formulated with dry ground corn (GC), high moisture corn silage (HMCS), dry ground sorghum with tannin (GSWT), high moisture whole sorghum with tannin silage (HMWSWTS), dry ground sorghum without tannin (GSWTT) or high moisture whole sorghum without tannin silage (HMWSWTTS). After cooling, the H&H sections of left half-carcasses were selected to estimate the tissue of carcass composition and the cuts in the Longissimus dorsi at 12th and 13th ribs to determine the rib eye area (REA), subcutaneous fat thickness (SFT), shear force (SF) and chemical composition. No treatment effects were observed on physical composition and relation among the tissues of H&H section and as for REA, SFT and SF. The concentrate ration HMCS showed higher content of EE in the Longissimus dorsi, but did not differ from GSWT and GSWTT. The concentrate ration HMCS promoted higher muscular fat deposition as compared to GC, but the concentrate rations HMWSWTS and HMWSWTTS did not show the same result as compared to the dry ground grains fed. All diets can be used in veal feedlot calves without effect on their carcasses tissue composition and meat tenderness. All evaluated feeds could be used in the concentrate rations for calves after weaning, because they do not impair physical and chemical carcass composition and confer similar results
