Social Physique Anxiety (SPA) has been associated with physical activity (PA) behaviors and anxiety disorder symptoms. However, little is known about the potential influence of SPA on associations between PA and Generalized Anxiety Disorder (GAD). PURPOSE: This study quantified associations between PA, GAD and SPA among young adults (N=470, 23.2±4.8y; 63.4% female) and explored SPA as a mediator of the association between PA and GAD. METHODS: Seven-day PA Recall determined estimated expenditure (kcal/wk) and classified inactive, moderately active, and highly active PA dose categories. The Psychiatric Diagnostic Screening Questionnaire GAD subscale assessed GAD symptom severity; a score of ≥6 indicated analogue GAD (AGAD) status. The Social Physique Anxiety Scale assessed SPA. Independent t-tests examined baseline differences based on gender and AGAD status. Cohen‘s d quantified the magnitude of difference. Logistic regression quantified odds of AGAD based on PA dose, adjusting for age, gender, and smoking status. Simple mediation analyses examined mediation of the continuous PA-GAD symptom association by SPA. RESULTS: Females reported less PA (p≤0.002, d=0.31) and greater SPA (p≤0.001, d=-0.63) and GAD symptom severity (p≤0.001, d=-0.51). AGAD reported greater SPA (p≤0.001, d=0.92). Compared to inactive, odds of AGAD were 28.3% (OR=0.72, 95%CI: [0.43, 1.20], p≥0.21) and 42.5% (OR=0.58, [0.35, 0.94], p≤0.03) lower among moderately active and highly active, respectively. In adjusted models, compared to inactive, odds were 29.3% (OR= 0.71, [0.42, 1.20], p≥0.21) and 36.9% (OR=0.63, [0.38, 1.06], p≥0.08) lower among moderately active and highly active, respectively. Regression models of PA on GAD symptoms (β=-0.01, p≤0.04), SPA on PA (β=-0.02, p≤0.03), and SPA on GAD symptoms (β=0.14, p≤0.001) were significant. When regressed together, SPA was (β=0.14, p≤0.001), but PA was not (β=-0.003, p≤0.27), statistically significant, supporting mediation. CONCLUSION: PA may lower odds of GAD, but findings were not significant after adjusting for covariates. SPA, a modifiable factor that was higher among females and those with AGAD, mediated the association between PA and GAD. Future research should examine these relationships longitudinally and explore SPA experimentally.

Angiotensin Receptor Neprilysin inhibitors (ARNi) is a new class of drug approved for heart failure patients with reduced ejection fraction (HFrEF). ARNi reduces resting blood pressure (BP) in HFrEF. However, the effect of ARNi on BP response to exercise in HFrEF has not been established. PURPOSE: We hypothesized that BP response to isometric handgrip exercise (IHG) would be attenuated in HFrEF after 12 weeks of ARNi therapy. METHODS: HFrEF participants were recruited from local cardiology clinics and completed a baseline experimental visit and follow up visit 12 weeks later: 6 patients were prescribed ARNi by their cardiologist [64±10 years, Men: 5, BMI: 30±6 kg/m, EF: 26±7%; 4 with Non-ischemic cardiomyopathy (NICM)], and 5 participants continued on conventional treatment [CON: 57±6 years, Men: 2, BMI: 27±5 kg/m, EF: 30±4% and NICM: 3; all P = NS]. During each experimental visit, BP was measured at rest and during 2-minutes IHG at 30% maximal voluntary contraction followed by post-HG exercise ischemia (PEI) to isolate the metaboreflex. The change in mean arterial pressure (∆ MAP) from baseline to exercise and PEI was assessed; statistical comparisons were performed using 2x2 repeated-measures ANOVA. RESULTS: At baseline, resting MAP was similar between ARNi (96±14 mmHg) and CON (86±12 mmHg; P=0.17) and MAP increased similarly during IHG (ARNi: ∆ 10±12 vs. CON: 8±10 mmHg) and PEI (ARNi: ∆ 6±4 vs. CON: 5±10 mmHg; ANOVA P>0.90). Resting MAP was reduced after 12 weeks of ARNi (87±7 mmHg) and was unchanged in CON (91±20 mmHg; ANOVA interaction P=0.048). However, the increase in MAP during IHG (ARNi: ∆ 11±8 vs. CON: 13±6 mmHg; P>0.60) and PEI (ARNi: ∆ 8±6 vs. CON: 12±3 mmHg; P>0.60) after 12 weeks was not impacted by ARNi (ANOVA time P=0.24) or different between groups. Maximal raw force and RPE ratings during IHG were similar between groups and not different following 12 weeks of ARNi (ANOVA P>0.70). CONCLUSION: These preliminary data suggest that although 12 weeks of ARNi therapy reduces resting MAP in HFrEF, there are no significant reductions on MAP response to exercise. Additional data are needed to fully understand the impact of ARNi on cardiovascular responses to exercise in HFrEF. Supported by ACSM grant 19-00934 and P20 GM 113125.

In the last decade, high intensity interval training (HIIT) has been shown to be an appropriate alternative to moderate-intensity, continuous exercise for improving cardiorespiratory fitness. HIIT protocols typically result in high blood lactate (La) levels. However, accumulated lactic acid is a potent metabolic stimulus, which plays a major role in the control of physiological adaptations. Therefore, it may be essential for improvements in endurance performance. The literature indicates that there is a strong positive relationship between maximum oxygen consumption (VO2max) and La production. PURPOSE: To investigate changes in La levels after 4 weeks of HIIT program. METHODS: Blood samples were collected from five female and five male student-athletes (n= 10) (Mage=21, SD=0.95). A short-term (4 weeks) HIIT protocol used and VO2max calculated through Course-Navette Test. The instruments used for this research were an Accutrend Plus-Roche lactometer and BM-Lactate test strips (Risch-Rotkreuz, Switzerland). The analysis consisted of t student tests for paired samples in IBM SPSS v.25 (p <0.001). RESULTS: VO2max and blood La changed significantly in six participants (Pre-La M=11.65mmol/L; Post-La M=9.41mmol/L). The participants that achieved to increase their VO2max, produced lower amounts of capillary blood La. CONCLUSION: Using HIIT, our study results confirm the positive relationship of VO2max and La. The inferences of these preliminary results could be used in future, larger-scale interventions concerning ways to affect La production through the increase of VO2max using a HIIT program. Future studies should further investigate anaerobic threshold modification processes through different training programs, such as Repeated Sprint Training (RST), Sprint Interval Training (SIT) and Moderate Intensity Continuous Training (MICT). Limitations of this study include small sample size and indirect VO2max estimation.

PURPOSE:Community-based exercise programs will be necessary to accommodate the volume of breast cancer survivors (BCS) in need of lifestyle/exercise guidance. However, attendance and enjoyment are critical components potentially preceding ideal outcomes. This study evaluated BCS compliance and satisfaction with 16-weeks of training at UNC Get REAL & Heel (GRH), a community-based exercise program. METHODS: BCS within 1 year of completing primary therapy (surgery, chemo, radiation) were prescribed 3, 1-hour days/week of combined aerobic and strength exercise training for 16 weeks at GRH. At exercise initiation, the intervention was designed to meet unique fitness/mobility needs of each BCS with gradual increases in intensity, duration, and volume of training. Compliance was the number of days BCS completed ≥80% of prescribed aerobic duration and strength sets/reps at the prescribed intensity using Borg Rating of Perceived Exertion scale. Satisfaction was captured with an agreement scale questionnaire: 1(strongly disagree) to 4(strongly agree) and open-ended feedback after program completion. RESULTS: Thirty-two BCS (mean±SD; age 54±12ys, BMI 27.5±5) participated. They attended 73% of exercise sessions; yet average compliance was 26±9.6 days (54%) for aerobic and 14±5.2 days (29%) for strength. Program expectation and enjoyment was 3.6±0.6, self-motivation and empowerment was 3.5±0.6, and patient desire to have participated during treatment was 3.5±0.6 in n=30 (94%) BCS who responded to the questionnaire. CONCLUSIONS: Attendance was acceptable yet compliance to exercise prescription was suboptimal. Increasing intensity, especially for strength, appeared to be the primary contributor to lack of compliance because volume and duration prescription components were frequently met. Nevertheless, there was overwhelming positivity regarding BCS enjoyment of program, confidence to exercise independently, and desire to have started exercising during treatment. Expanding GRH days and hours/day was a recurring feedback theme and may have improved attendance.

目的:以社区为基础的运动项目将是必要的，以适应需要生活方式/运动指导的乳腺癌幸存者(BCS)的数量。然而，出席和享受是理想结果之前的关键因素。这项研究评估了在UNC Get REAL & Heel (GRH)进行的为期16周的训练对BCS的依从性和满意度，GRH是一项基于社区的锻炼计划。方法:BCS在完成主要治疗(手术、化疗、放疗)后1年内，在GRH进行为期16周的有氧和力量运动联合训练，每周3、1小时。在运动开始时，干预措施的设计是为了满足每个BCS独特的健康/活动需求，并逐渐增加强度、持续时间和训练量。依从性是指BCS在规定强度下完成≥80%的规定有氧持续时间和强度集/次的天数(使用Borg分级感知运动量表)。满意度是通过一个协议量表问卷来获得的:1(非常不同意)到4(非常同意)，并在项目完成后提供开放式反馈。结果:32个BCS (mean±SD;年龄54±12ys, BMI 27.5±5)。他们参加了73%的锻炼课程;有氧运动的平均依从性为26±9.6天(54%)，力量运动的平均依从性为14±5.2天(29%)。在n=30(94%)答复问卷的BCS中，项目期望和享受为3.6±0.6，自我激励和授权为3.5±0.6，患者参与治疗过程的愿望为3.5±0.6。结论:出勤是可以接受的，但运动处方的依从性是次优的。增加强度，特别是强度，似乎是缺乏依从性的主要原因，因为剂量和持续时间的处方成分经常得到满足。然而，在BCS享受项目、独立锻炼的信心和在治疗期间开始锻炼的愿望方面，有压倒性的积极。扩大GRH天数和小时数是一个反复出现的反馈主题，可能会提高出勤率。这些因素对于未来的方案设计很重要，以最好地适应BCS在癌症治疗后恢复生理和日常生活的挑战。资助:乳腺癌研究基金会(纽约，纽约)。

However, attendance and enjoyment are critical components potentially preceding ideal outcomes. This study evaluated BCS compliance and satisfaction with 16-weeks of training at UNC Get REAL & Heel (GRH), a community-based exercise program. METHODS: BCS within 1 year of completing primary therapy (surgery, chemo, radiation) were prescribed 3, 1-hour days/week of combined aerobic and strength exercise training for 16 weeks at GRH. At exercise initiation, the intervention was designed to meet unique fitness/mobility needs of each BCS with gradual increases in intensity, duration, and volume of training. Compliance was the number of days BCS completed ≥80% of prescribed aerobic duration and strength sets/reps at the prescribed intensity using Borg Rating of Perceived Exertion scale. Satisfaction was captured with an agreement scale questionnaire: 1(strongly disagree) to 4(strongly agree) and open-ended feedback after program completion. RESULTS: Thirty-two BCS (mean±SD; age 54±12ys, BMI 27.5±5) participated. They attended 73% of exercise sessions; yet average compliance was 26±9.6 days (54%) for aerobic and 14±5.2 days (29%) for strength. Program expectation and enjoyment was 3.6±0.6, self-motivation and empowerment was 3.5±0.6, and patient desire to have participated during treatment was 3.5±0.6 in n=30 (94%) BCS who responded to the questionnaire. CONCLUSIONS: Attendance was acceptable yet compliance to exercise prescription was suboptimal. Increasing intensity, especially for strength, appeared to be the primary contributor to lack of compliance because volume and duration prescription components were frequently met. Nevertheless, there was overwhelming positivity regarding BCS enjoyment of program, confidence to exercise independently, and desire to have started exercising during treatment. Expanding GRH days and hours/day was a recurring feedback theme and may have improved attendance. These factors are important for future program designs to best accommodate BCS returning to physiological and daily life challenges following cancer treatment.
