Y líbranos del mal by Santiago Roncagliolo

Reviewed by: Y líbranos del mal by Santiago Roncagliolo Sandra Chang Raak Santiago Roncagliolo Y líbranos del mal Mexico City. Seix Barral. 2021. 394 pages. IN Y LÍBRANOS DEL MAL, Santiago Roncagliolo’s latest novel, the Peruvian author and winner of the prestigious Premio Alfaguara portrays a fictionalized version of the widely publicized scandals of Sodalicio, a Catholic community in the Andean country. In this novel, unlike other published accounts, Roncagliolo explores an innovative point of view, that of Jimmy, a college-aged young man who doesn’t know of his father’s involvement in that faith community. Through Jimmy, Roncagliolo explores the deeply rooted religious beliefs that are perpetuated from one generation to the next. Roncagliolo’s novel presents at least two different chronologies. The first features Jimmy, who was born to Peruvian immigrants and raised in the United States. The second is the story of Jimmy’s father, Sebastián, which is unveiled while Jimmy cares for his ailing grandmother, Tita, in a well-off neighborhood in Lima. Jimmy learns about Sebastián’s past and discovers multiple testimonies that “collapse[s] the past into the present, making it seem or feel as if it were more ‘real’ and ‘present’ than contemporary circumstances” (LaCapra, Writing History, Writing Trauma). By naming evils from the past and bringing them into the present, Roncagliolo empowers those who, as in Y líbranos del mal, have experienced abuse and violence at the hands of authoritative institutions. Unsurprisingly, however, this is a novel in which circumstances are never entirely clear, nor do they need to be in order to understand the events. This ambiguity permeates the novel in its entirety and reflects the lack of trust, essential to the national character, and an acquiescent personality, key to understanding many Peruvians. Even though Roncagliolo resides in Spain, he accurately captures elements of the Peruvian worldview in the context of a very relevant institution in Latin American society: a traditional, Catholic family. As in previous novels, Roncagliolo reflects on ignominious portions of Peruvian history. In Red April (2006), Roncagliolo criticized the actions that the government of Alberto Fujimori took against the terrorist group Sendero Luminoso. The prequel, La pena máxima (2014), is set in a soccer-filled Lima, crowded with fans that supported the national team in the 1978 World Cup. In the background, however, duplicitous characters swarm the streets of the capital because they are interested in eliminating all communist threats. Y líbranos del mal sparked my desire to learn more about contemporary Peruvian history, particularly the historic events that inform this work of fiction. Unlike Mitad monjes, mitad soldados, by Pedro Salinas, which gathers testimonies from the victims, Roncagliolo’s novel explores the aftereffects of growing up in a society where the Catholic church occupies, indisputably, a very important place.

MHealth video gaming for human papillomavirus vaccination among college men-qualitative inquiry for development.

BackgroundHuman papillomavirus (HPV) is the most common sexually transmitted infection in the United States. Persistent infection with HPV can cause various cancers; however, HPV vaccination can prevent infections associated with high risk, cancerous strains of the virus. As it relates to HPV, college age men have been identified as one of the catch-up vaccination groups. Among college age men, gaming is an extremely popular extracurricular activity. Further, video games have emerged as a popular public health intervention tool. Therefore, this study aims to collect qualitative data on how to develop, implement and evaluate the effectiveness of a gaming intervention to increase HPV risk perceptions, improve self-efficacy and increase intention to receive the HPV vaccine among male college students (18–26 years old).MethodsFour focus group sessions ranging from eight to ten individuals were conducted among male college students from one large research-intensive university in the South. Using grounded theory, data from focus group interviews were coded using NVivo software to identify emergent themes.ResultsParticipants emphasized that although customization was not viewed as important by college aged males, the ability to tailor in game experiences or experience different things each time they played (creative freedom) was more important. They encouraged that the digital game be created on a mobile platform, incorporate health messages, and be informative to reach their population. Furthermore, they suggested innovative way to disseminate the game, which included having health department/health care providers prescribe the game to patients as an end of clinical interaction strategy.ConclusionsCollege age men, are natural avid gamers, enjoy game play, and can engage in learning online or offline. While platform preference varies among gamer type, college age men in our study emphasized that mobile based gaming is the most advantageous way to increase knowledge/awareness and encourage positive in game behavior which can impact out of game behaviors such as vaccination. Because of the level of access and natural disposition of mHealth technology seen as an “extension of the self”, games for health developers should consider the mobile platform as the ideal for the target demographic.

Hormonal Male Contraception: Formative Research to Develop and Test Communication Messaging.

Male-controlled contraception is limited, yet a promising hormonal male contraceptive (HMC) development in may increase options for men to share in the work of pregnancy prevention. This study examined college-aged (18–26 years) men’s and women’s perceptions of influential marketing strategy for an experimental novel HMC method, a transdermal gel. Six focus groups (n = 29) were conducted to glean insights for ad prototype creation. Ad prototypes were designed and then tested in semi-structured interviews (n = 20) to understand whether the messages were adequately representing the attributes intended while also allowing participants to contribute insights on improving appeal. A constant comparative approach was used for data contextualization and theme identification. Results provided a foundation for the creation of HMC message prototypes, aimed at increasing knowledge and uptake of a novel family planning method for men. Representation of a relatable character, or drawing on authentic experiences, aligned best with participant values. Focus groups illuminated salient concepts for HMC marketing, including humor, destigmatization, information, and credibility. Interview message testing yielded an understanding of elements participants responded most strongly to, including (1) ad sentiment and (2) trustworthiness. Findings provide a basis for understanding the placement of a potential marketing campaign to effectively frame HMC uptake as easy to use, safe, and popular while building on peer norms and group acceptability among a college-aged demographic. Healthcare providers and other practitioners can utilize these findings while engaging in family planning conversations, interventions, and message development.

Effects of different types of resistance exercise failure training on the methylation status of genes that drive skeletal muscle hypertrophy

ObjectiveWe sought to determine how one bout of resistance training to failure with either higher repetitions (30FAIL) or lower repetitions (80FAIL) affected the promoter methylation statuses of genes that drive skeletal muscle hypertrophy.HypothesesWe hypothesized that a bout of 80FAIL training would lead to a more robust hypomethylation of genes that regulate skeletal muscle hypertrophy compared to 30FAIL training.MethodsEleven previously‐trained college‐aged men (age: 23 ± 4 years, 11.42 ± 6.38 percent fat, 4 ± 3 years training experience) volunteered for this study. Each participant underwent two training bouts (spaced one week apart) involving either: i) 30FAIL training; 4 sets of back squats and 4 sets of leg extensors to failure at 30% of one‐repetition maximum (1RM), or: ii) 80FAIL training; 4 sets of both exercises at 80% of 1RM. Muscle biopsies from the vastus lateralis were collected prior to each bout (PRE), 3 hours following each bout (3hPOST), and 6 hours following each bout (6hPOST). Following the conclusion of the study, tissue was batch‐processed for DNA isolation, and DNA was subjected to the Illumina MethylationEPIC array. In an a priori fashion, genes that have been shown to induce skeletal muscle hypertrophy in genetic mouse models were the target of this investigation (Verbrugge et al. Frontiers Physiol, 2019).ResultsTotal training volume (sets x reps x load) between the 30FAIL and 80FAIL bouts were not significantly different (p= 0.571). Differentially methylated region changes for the following genes from PRE to 3hPOST and PRE to 6hPOST are presented herein: SKI, FST, AKT1, ACVR2B, MSTN, KLF10, RHEB, IGF1, PAPPA, PPARD, IKBKB, FSTL3, ATGR1, UCN3, MCU, JUNB, NCOR1, GPRASP1, GRB10, MMP9, DGKZ, PPARGC1A, SMAD4, LTBP4, BMPR1A, CRTC2, XIAP, DGAT1, THRA, ADRB2, ASB15, CAST, EIF2B5, BDKRB2, TPT1, NR3C1, NR4A1, GNAS, PLD1, CRYM, CAMKK1, YAP1, INHBA, TP53INP2, INHBB, NOL3, and ESR1. Additionally, significant differences between conditions at each time point are highlighted.ConclusionsThis study continues to display how different modalities of resistance training affect the skeletal muscle molecular milieu and furthers our scientific understanding of factors that contribute to training adaptations.

Log-Transformed Electromyography Amplitude Power Output Relationship: Nondominant vs. Dominant Limb.

Boccomino, HL, Daoud, BT, Hudas, A, North, WA, and Malek, MH. Log-transformed electromyography amplitude power output relationship: nondominant vs. dominant limb. J Strength Cond Res 36(3): 851-856, 2022-Findings from studies that examine bilateral differences between the nondominant and dominant limb during whole-body (i.e., cycle ergometry) are equivocal. This may, in part, be because of the mode of exercise (i.e., whole-body) and how the data are analyzed. Surface electromyography (EMG) is a noninvasive method of examining motor unit recruitment and activation during exercise. The log-transformed electromyography amplitude power output relationship provides y-intercept and slope terms on a subject-by-subject basis that can therefore be statistically analyzed. The purpose of this study, therefore, was to identify potential differences in the muscle for the nondominant and dominant limb using the log-transformed EMG amplitude power output relationship for continuous exercise that isolates the quadricep femoris muscles. Nine healthy college-aged men (mean ± SEM: age, 22.6 ± 1.2 years; mass, 68.6 ± 10.4 kg; and height, 1.76 ± 0.03 m) volunteered as subjects for the current study. Each subject visited the laboratory on a single occasion, had EMG electrodes placed on their rectus femoris muscle for their nondominant and dominant limb, and performed an incremental double-leg knee-extensor ergometry to voluntary exhaustion. The subjects achieved a mean power output (75 ± 8 W) for the exercise test. In addition, a mean end-exercise heart rate (155 ± 8 b·min-1) corresponded to 79 ± 4% of the age-predicted heart rate using the formula 220-age. Separate paired t tests for the slope (t[8] = 0.929 p = 0.38) and y-intercept (t[8] = 0.368, p = 0.72) terms revealed no significant mean differences between the 2 limbs. The results of the present study indicate that there are no differences in muscle activation between the nondominant and dominant limbs for continuous exercise that isolates the muscle.

Nonfatal Suicidal Behavior among a Sample of College Students: The Role of Gender as a Risk and Protective Factor

ABSTRACT In the United States, suicide is a leading cause of death among college-aged persons, particularly among men. However, while college-aged men are at higher risk for suicide, it is women who exhibit higher incidences of nonfatal suicidal behavior. Nonfatal suicidal behavior (NFSB) includes acts such as suicidal ideation, self-injury, and suicide attempt. Expanding the research on the gender gap in suicidal behaviors by drawing on a contemporary gender socialization framework, this study examines the role of various gender dimensions and NFSB. Utilizing data from a survey of college students, we find that the gender dimensions, Nurture/Warmth and Affect, operate as risk and protective factors in the use of NFSB for men and women.

Sleep reactivity is associated with social anxiety and disordered-eating behaviors in college students

Objective: Investigate whether sleep reactivity was associated with social anxiety and disordered-eating behaviors in a college population. Participants: One hundred ninety-eight college-age men and women. Methods: Participants completed self-report measures of social anxiety, disordered-eating behaviors and sleep reactivity. Results: Sleep reactivity was associated with greater dietary restriction and purging, controlling for social anxiety but it was not associated with binge eating. Sleep reactivity was associated with elevated symptoms of social anxiety, controlling for disordered-eating behaviors. Conclusions: The results suggest that sleep reactivity represents a shared correlate of disordered-eating behaviors and social anxiety that may partially explain their co-occurrence. Interventions to help college students high in sleep reactivity effectively manage stress and regulate their sleep may aid in the prevention and treatment of social anxiety and disordered-eating behaviors.

Dispelling a Myth: Reevaluating the Predictive Validity of Rape Myth Acceptance for Likelihood of Engaging in Sexual Violence.

Sexual violence prevention on college campuses has received significant recent attention. A prevalent intervention paradigm has centered around re-educating young people around consent and reduce endorsement of "rape myths," based on the correlation between rape myths and sexual violence incidents. Yet many of these programs have not measurably reduced sexual assaults. We evaluated the predictive value of a rape myth measure, as compared with other predictors (criminal history, childhood victimization, aggressive tendencies, substance use, and empathy), in predicting self-reported acts of forcible and incapacitated sexual assault in college-age men (N = 304) from 45 U.S. states. Across three logistic regression model pairs, rape myths were weakly associated with violence when considered as sole predictors. However, this predictive power dissipated when other predictors were included. Comprehensive models accounted significantly better for variability in outcomes; with criminal history demonstrating consistent predictive effects. Based on these findings, we recommend further research into prevention programming based on other predictors of violence.

Molecular Differences in Skeletal Muscle After 1 Week of Active vs. Passive Recovery From High-Volume Resistance Training.

Vann, CG, Haun, CT, Osburn, SC, Romero, MA, Roberson, PA, Mumford, PW, Mobley, CB, Holmes, HM, Fox, CD, Young, KC, and Roberts, MD. Molecular differences in skeletal muscle after 1 week of active vs. passive recovery from high-volume resistance training. J Strength Cond Res 35(8): 2102-2113, 2021-Numerous studies have evaluated how deloading after resistance training (RT) affects strength and power outcomes. However, the molecular adaptations that occur after deload periods remain understudied. Trained, college-aged men (n = 30) performed 6 weeks of whole-body RT starting at 10 sets of 10 repetitions per exercise per week and finishing at 32 sets of 10 repetitions per exercise per week. After this period, subjects performed either active (AR; n = 16) or passive recovery (PR; n = 14) for 1 week where AR completed ∼15% of the week 6 training volume and PR ceased training. Variables related to body composition and recovery examined before RT (PRE), after 6 weeks of RT (POST), and after the 1-week recovery period (DL). Vastus lateralis (VL) muscle biopsies and blood samples were collected at each timepoint, and various biochemical and histological assays were performed. Group × time interactions (p < 0.05) existed for skeletal muscle myosin heavy chain (MHC)-IIa mRNA (AR > PR at POST and DL) and 20S proteasome activity (post-hoc tests revealed no significance in groups over time). Time effects (P < 0.05) existed for total mood disturbance and serum creatine kinase and mechano growth factor mRNA (POST > PRE &D L), VL pressure to pain threshold and MHC-IIx mRNA (PRE&DL > POST), Atrogin-1 and MuRF-1 mRNA (PRE < POST < DL), MHC-I mRNA (PRE < POST & DL), myostatin mRNA (PRE & POST < DL), and mechanistic target of rapamycin (PRE > POST & DL). No interactions or time effects were observed for barbell squat velocity, various hormones, histological metrics, polyubiquitinated proteins, or phosphorylated/pan protein levels of 4E-BP1, p70S6k, and AMPK. One week of AR after a high-volume training block instigates marginal molecular differences in skeletal muscle relative to PR. From a practical standpoint, however, both paradigms elicited largely similar responses.

Effects of Transdermal Methylsulfonylmethane on Muscle Damage and Recovery Following Eccentric Exercise

PURPOSE:The present study aimed to investigate the effects of transdermal application of methylsulfonylmethane (MSM) on muscle damage and recovery following eccentric exercise in young men.METHODS: Eleven college-aged men without any cardiovascular or orthopedic disorders underwent two sessions consisting of a control session (CS) and an experimental session (ES) in a random order with at least 2 weeks of wash-out between the sessions. The participants performed 30 maximal eccentric exercises involving their non-dominant elbow flexors in each session. Circumference, muscle soreness, range of motion, maximal voluntary isometric contraction (MVIC), and muscular echo intensity (EI) were measured to evaluate the changes in the level of exercise-induced muscle damage (EIMD). All measurements were performed at 24, 48, 72, and 96 hours after exercise and also immediately before and after exercise.RESULTS:Transdermal application of MSM in ES attenuated muscle swelling and decreased MVIC after eccentric exercise when compared with CS. Muscle soreness and EI tended to increase less rapidly and decrease more rapidly in ES than in CS.CONCLUSIONS: Transdermal application of MSM may induce relatively positive effects on EIMD and recovery following eccentric exercise when compared with the treatment that has been widely used previously.

Tinder: A Game with Gendered Rules and Consequences

The popularity of Mobile Dating Applications has increased in recent years, with Tinder transforming the dating landscape for college students. Drawing upon 249 peer-facilitated interviews with college-age men and women, we explore how this population uses Tinder. Informed by social-psychological theory and research on impression management and stereotyping, we show how Tinder’s marketing strategy and game-like platform appeal to college students’ desires to reduce uncertainty and risk in forming romantic and intimate connections. However, by upending existing interaction norms, the Tinder environment creates new forms of ambiguity, which, in turn, incentivizes conformity to traditional heterogender norms and encourages racist and classist swiping behavior. Our study advances the literature on inequality and intimate marketplaces by generating insight about how contemporary dating and sexual scripts are constructed, accomplished, and negotiated when new technologies disrupt established patterns of interaction.

Characterizing Loss of Control Associated With Binge Eating in College-Age Men.

The Diagnostic and Statistical Manual of Mental Disorders (5th ed.) identifies key features of binge eating (BE) to include the consumption of a large amount of food and the perception of loss of control (LOC) over eating during a distinct episode. While earlier research has focused on food consumption, findings are now emerging on the role of LOC associated with the BE episodes, particularly in women. However, it is unclear that these findings are applicable to men without knowing how men experience LOC associated with BE. This study examined how college-age men describe LOC associated with BE. Previously collected qualitative data from a study examining BE in college age-students were used to examine responses from 53 men (mean age 19.9 ± 1.1 [SD] years). Respondents were asked about their individual experiences of LOC associated with BE episodes. Data were analyzed using content analysis. Four categories emerged from the data: (1) keep eating, (2) can't stop, (3) without thinking, and (4) food so good. Findings extend the current understanding of LOC associated with BE in men and point to potential gender differences, and/or weight influences, based on previous reports. Identified categories may be potentially targeted areas for tailored therapy to enhance awareness and self-regulation of BE behavior.

A Comparison of Methods Used to Determine Percent Body Fat, Minimum Wrestling Weight, and Lowest Allowable Weight Class.

Cutrufello, PT, Landram, MJ, Venezia, AC, and Dixon, CB. A comparison of methods used to determine percent body fat, minimum wrestling weight, and lowest allowable weight class. J Strength Cond Res 35(3): 633-637, 2021-The National Collegiate Athletic Association's weight management program allows for the use of skinfold measurements (SF), air displacement plethysmography (ADP), and hydrostatic weighing in the assessment of percent body fat (%BF) and determination of a wrestler's minimum wrestling weight (MWW). Dual energy x-ray absorptiometry (DXA) and ultrasound (US) may offer alternative assessment methods. The purpose of this study was to examine %BF, MWW, and the lowest allowable weight class as determined by SF, ADP, DXA, and US. Thirty-three college-aged men (20.8 ± 1.1 years) participated. Urine specific gravity (Usg) was assessed to ensure proper hydration (1.006 ± 0.006). Percent body fat and MWW were then determined using the 4 assessment methods. Each method was significantly different from one another (p < 0.05) with the exception of ADP compared with SF (17.6 ± 7.1% vs. 17.4 ± 6.3%, p = 1.000) and DXA compared with US (20.5 ± 6.2% vs. 19.2 ± 7.5%, p = 0.124). DXA (68.6 ± 7.1 kg) and US (69.3 ± 6.0 kg) determined the lowest MWW, whereas those determined by SF (70.8 ± 6.8 kg) and ADP (70.9 ± 6.6 kg) were significantly greater (p< 0.05). The SEEs for MWW when compared with SF were 3.2, 3.4, and 2.4 kg for ADP, DXA, and US, respectively. Compared with SF, DXA and US would allow wrestlers to certify at a lower weight class 64 and 33% of the time, respectively. When comparing the approved methods (SF and ADP), approximately 50% of subjects would certify at a different weight class depending on the method used. The use of different methods in assessing %BF offer a wide variability in the determination of MWW.

Perceived Consumption of a High-Dose Caffeine Drink Delays Neuromuscular Fatigue.

Elhaj, HM, Imam, O, Page, BW, Vitale, JM, and Malek, MH. Perceived consumption of a high-dose caffeine drink delays neuromuscular fatigue. J Strength Cond Res 36(5): 1185-1190, 2022-The placebo effect is a concept in which a desired outcome arises, mainly from the belief that the treatment (i.e., supplement or drug) was beneficial although no active ingredient was given. The results of studies related to the placebo effect primarily examine functional performance. What remains unanswered, however, is whether these changes in performance are associated with neuromuscular alterations in the exercised muscles. The purpose of the study, therefore, was to determine the influence of the placebo effect on the physical working capacity fatigue threshold (PWCFT) for a continuous exercise paradigm. To achieve this aim, subjects were told that they were participating in a study to determine the dosage response (low or high) of caffeine on neuromuscular fatigue when in fact no caffeine was given during the experiment. We hypothesized that the perceived consumption of the high-dose caffeine drink would result in a higher PWCFT than the perceived consumption of the low-dose caffeine drink and placebo. Secondarily, we hypothesized that the perceived consumption of the high-dose caffeine drink would result in a higher power output than the perceived consumption of the placebo. Nine healthy college-aged men (mean ± SEM: age, 25.7 ± 1.3 years; body mass, 84.4 ± 3.1 kg; and height: 1.82 ± 0.02 m) volunteered to be in the study. For each of the visits, subjects were given an 8 oz. bottle of water with dissolved crystal light. After the drink was consumed, subjects rested in the laboratory for 1 hour before performing the incremental single-leg knee-extensor ergometry. Immediately after the termination of the incremental single-leg knee-extensor ergometry, the subject was asked which caffeine dose (placebo, low, or high) they believed they consumed for that visit. There were no significant mean differences for maximal power output for the 3 perceived conditions (placebo: 62 ± 3, low-dose caffeine: 62 ± 4, and high-dose caffeine: 65 ± 3 W). When the subjects perceived consuming the high-dose caffeine drink, there were significant mean differences (all p-values < 0.01), for PWCFT, between the other conditions (mean ± SEM: placebo: 23 ± 3 W, low-dose caffeine: 26 ± 2 W, and high-dose caffeine: 42 ± 3 W). This corresponded to a significant mean difference (all p-values < 0.01) when the PWCFT was presented as a percentage of the maximal power output (mean ± SEM: placebo: 37 ± 5%, low-dose caffeine: 42 ± 3%, and high-dose caffeine: 64 ± 3%). The application of our results may indicate that the subject's expectancy, to caffeine consumption, plays a critical role in delaying the onset of neuromuscular fatigue despite not receiving any caffeine in their drinks.

Evaluating a Technology-Mediated HPV Vaccination Awareness Intervention: A Controlled, Quasi-Experimental, Mixed Methods Study.

College-aged women and men are an important catch-up population for human papillomavirus (HPV) vaccination interventions. Limited research has explored technology-mediated HPV vaccination awareness interventions aimed at college students. The purpose was to evaluate a novel, technology-mediated, social media-based intervention to promote HPV vaccination among college students. A controlled, quasi-experimental, mixed methods study examined the feasibility of a technology-based intervention among two undergraduate classes (n = 58) at a public university in the southeastern United States of America. Classes were randomized to receive one of two cancer prevention programs (i.e., HPV vaccination (intervention) or healthy weight (control)). Both programs contained eight technology-mediated sessions, including weekly emails and private Facebook group posts. Participants completed pre-/post-test surveys and submitted weekly qualitative reflections. Data were analyzed using descriptive statistics and thematic review for qualitative data. Knowledge improved among participants in the HPV vaccination intervention relative to those in the control condition. Participants (97%) interacted on Facebook by “liking” a post or comment or posting a comment. Participants demonstrated robust engagement and high treatment satisfaction. Results suggests that social media is an effective platform to reach college students with health promotion interventions and increase HPV vaccination awareness in this important catch-up population.

Cardiac Autonomic Responses and Adaptation to Repeated Bouts of Eccentric Exercise

PURPOSE:The current study was performed to examine the effects of acute eccentric resistance exercise (ERE) on heart rate variability (HRV) and to determine whether cardiac autonomic regulation adapts to the repeated bout effect.METHODS: Isokinetic eccentric exercise consisted of five sets of six maximal contractions of the knee extensor with an angular velocity of 90°/second. College-aged men (n=11) underwent two sessions of ERE with a 3-week interval. Muscle damage indicators such as the range of motion (ROM) and muscle echo intensity (EI) were measured. The post-exercise cardiac autonomic response was assessed by spectral analysis of HRV. Low frequency (LF) and high frequency (HF) bands, the normalized unit (nu) for each band power, and the LF-to-HF (LF/HF) ratio were determined. All variables were recorded at 24, 48, 72, and 96 hours post-exercise as well as before and immediately after ERE.RESULTS:The EI and ROM of the rectus femoris changed significantly after the maximal ERE. There was a significant interaction effect between the time and bout for EI. Significant changes in LF and HF nu were observed at 72 (1st ERE) and 96 hours (2nd ERE) after each ERE. The LF/HF ratio was also significantly increased at 24 (1st ERE) and 72 hours (2nd ERE) after each ERE. However, no interaction effects on changes in the HRV indices were observed.CONCLUSIONS: The present study suggests that acute ERE leads to cardiac autonomic imbalance for a sustained period and that repeated bouts of ERE cannot alleviate cardiac autonomic responses to exercise.

The Effects of the Barbell Hip Thrust on Post-Activation Performance Enhancement of Change of Direction Speed in College-Aged Men and Women.

This study investigated whether the barbell hip thrust (BHT) enhanced change-of-direction (COD) speed measured by the 505 COD speed test. Forty recreationally trained individuals completed three sessions. Session 1 included one-repetition maximum (1RM) BHT testing to measure absolute and relative strength. Sessions 2 and 3 involved two counter-balanced conditioning activities (CAs): 3 sets × 5 repetitions of the BHT at 85% 1RM and a control condition (CC; 6 min rest). The 505 COD speed test was performed 5 and 2.5 min pre-CA, and 4, 8, 12, and 16 min post-CA in each session. A 2 × 5 repeated-measures ANOVA (p < 0.05) calculated performance changes across time post-CA. A 2 × 2 repeated-measures ANOVA analyzed best potentiated performance. Partial correlations controlling for sex calculated relationships between the 1RM BHT and 505 COD speed test percent potentiation. There was a significant main effect for time (p < 0.001), but not for condition (p = 0.271) or condition × time (p = 0.295). There were no significant correlations between 1RM BHT and potentiation. The 85% 1RM BHT did potentiate the 505 4–16 min post-CA but no more than the CC. Nonetheless, a heavy BHT could be programmed prior to COD drills as COD speed could be potentiated and performance improved in men and women.

HPV Vaccine and College-Age Men: A Scoping Review.

The human papillomavirus (HPV) potentially affects every sexually active man in the United States and Canada. In 2017, the vaccine became publicly funded in Canada for males ages 9–26, and was integrated into school vaccination programs. In 2019, HPV vaccination was recommended as routine for all U.S.-based males and females ages 9 through 26, and a shared decision for adults >26 years; however, since the approval of the vaccine in 2006 for females only, the age and dosing recommendations for males have followed a complicated and changing trajectory. Current adherence rates are low among college and university age males (18–26 years); therefore, understanding and addressing the barriers and facilitators for men’s HPV vaccination is critically important. The purpose of the current scoping review is to provide a synthesis of recent literature pertaining to HPV in college and university age men, as a means to guiding health-care providers (HCPs). Drawing from 15 published articles, three thematic findings were inductively derived. Theme one, lack of awareness, was underpinned by men’s knowledge deficits about their eligibility for, and the availability of HPV vaccines. Theme two, underestimating and embodying risk, included men’s engagement in sexual activities while misinformed or denying the risk for contracting HPV. The third theme, strategies for increasing men’s awareness, summarizes messaging strategies used to lobby young men to vaccinate. The review findings indicate gender-sensitive interventions targeting college-age men, including early, frequent, and consistent messaging on HPV are key.

The evolving nature of weight dissatisfaction and eating behaviors among men: Secular trends among college men across four decades.

Research supports increasing cultural pressures for leanness among young men; however, few studies have examined whether weight dissatisfaction or efforts to alter weight have become more prevalent for men over time. The present study evaluated secular trends in weight dissatisfaction and related behaviors among college-age men across 4 decades; 1,097 men completed surveys while they were in college in 1982 (n = 276), 1992, (n = 233), 2002 (n = 241), and 2012 (n = 347). In 1982, men with a body mass index (BMI) between 18.5 and 25 kg/m2 were more likely to describe themselves as being overweight compared with men in all other cohorts, whereas in 1992, 2002, and 2012, men with a BMI between 18.5 and 25 kg/m2 were more likely to describe themselves as underweight compared with men in all other cohorts. Overall, 57-62% of men reported weight dissatisfaction, although there were no significant differences in the proportion of men wanting to lose, maintain, or gain weight across cohorts. There was no significant difference in the amount of weight gain desired across cohorts despite increasing BMI from 1982 to subsequent cohorts; however, desired BMI and endorsement of fad diets differed across cohorts, with higher desired BMI in 1992 and 2002 and high-protein diets being the most common in 2012. These results suggest that weight dissatisfaction has remained substantial and relatively stable among young men over time. Trends relating to weight perception, dieting, and exercise are consistent with an increasing focus on leanness and muscularity for men in recent years.
