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.","PeriodicalId":14781,"journal":{"name":"Journal is not defined within the JOURNAL database.","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84866726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

Rivera, José Eduardo Molina Arriola, Víctor Osiris Rodríguez Cervantes, A. Stamatis","doi":"10.1249/01.mss.0000686692.50198.ac","DOIUrl":"https://doi.org/10.1249/01.mss.0000686692.50198.ac","url":null,"abstract":"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.","PeriodicalId":14781,"journal":{"name":"Journal is not defined within the JOURNAL database.","volume":"98 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84935876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
