Conclusions: HIIT is an effective method to improve CRF in adolescents, irrespective of body composition. Notably, meta regression analysis identified that prolonged high volume HIIT programs are similarly effective to short term low volume HIIT programs. This becomes of particular interest for those involved in school curricula, where short HIIT exercise may provide a pragmatic adjunct to the health benefits of Physical Education (PE) lessons. © 2020 by the authors.

Methods: Electronic databases were searched from inception to January 2018 before conducting a random-effects meta-analysis to calculate pooled differences in means, effect size and 95% confidence intervals (CIs). Study heterogeneity was reported using Cochran’s Q and I2 statistic. Results: Overall, 32 studies (644 athletes; 582 controls) were included. Athletes had greater LV end-diastolic diameter (3.65 mm, 95% CI 2.66–4.64), interventricular septal thickness (1.23 mm, 95% CI 0.85–1.60), posterior wall thickness (1.20 mm, 95% CI 0.83–1.56), LV mass (72 g, 95% CI 46–98), LV mass index (28.17 g·m2, 95% CI 19.84–36.49) and stroke volume (13.59 mL, 95% CI 7.20–19.98) (all p < 0.01). Athletes had superior global diastolic function [ratio of early (E) to late (A) mitral inflow velocity (E/A) 0.18, 95% CI 0.13–0.24, p < 0.01; ratio of early (e′) to late (a′) diastolic annular tissue velocity (e′/a′) 0.23, 95% CI 0.06–0.40, p = 0.01], lower A (−8.20 cm·s−1, 95% CI −11.90 to −4.51, p < 0.01) and a′ (−0.72 cm·s−1, 95% CI −1.31 to −0.12, p = 0.02), and more rapid e′ (0.96 cm·s−1, 95% CI 0.05–1.86, p = 0.04). Meta-regression for chronological age identified that athlete–control differences, in the main, are maintained during advancing age. Conclusions: Athletic older men have larger cardiac dimensions and enjoy more favourable cardiac function than healthy, non-athletic counterparts. Notably, the athlete groups maintain these effects during chronological ageing. © 2018, The Author(s).]]> Wed 07 Apr 2021 14:01:52 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13501 Wed 07 Apr 2021 14:01:38 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13227 Wed 07 Apr 2021 14:01:23 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11811 Wed 07 Apr 2021 13:57:06 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11795 0.04 ng/mL), after performing high-intensity cycle ergometer sprints. As creatine kinase (CK) is expressed by multiple organs (e.g., skeletal muscle, brain, and myocardium), cTnI assays were performed to determine any changes in total serum CK levels not originating from skeletal muscle damage. Diagnosis: A posteriori the individual's daily energy expenditure indicated chronically low-energy availability. Psychometric testing suggested that the individual scored positive for disordered eating, highly for fatigue levels, and low in mental health components. Outcomes: The current case report provides novel evidence of elevated cTnI occurring as a result of performing short duration, high intensity, cycle ergometer exercise in an individual with self-reported chronically depleted energy balance. A schematic to identify potentially “at risk” individuals is presented. Lessons: Considering this as a case report, results cannot be generalized; however, the main findings suggest that individuals who habitually restrict their calorie intake below their bodies’ daily energy requirements, may have elevated biomarkers of exercise induced myocardial stress from performing high-intensity exercise.]]> Wed 07 Apr 2021 13:57:05 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11801 Wed 07 Apr 2021 13:57:05 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11803 Wed 07 Apr 2021 13:57:05 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11804 Wed 07 Apr 2021 13:57:05 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11807 Wed 07 Apr 2021 13:57:05 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11788 Wed 07 Apr 2021 13:57:04 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11794 0.05).

Participants underwent a resting electrocardiogram (ECG), from which, the QTc interval was calculated using the Bazett formula. The main outcome measure was significant differences in mean corrected QTc between groups. A secondary outcome was to calculate a QTc that best differentiated between C and AS. Results indicated that QTc was shorter in AS than in C (382.0 +/- 21.01 ms versus 409 +/- 18.77 ms for AS and C respectively p < 0.001). Chi squared analyses revealed a greater incidence of QTc < 380 ms in AS versus C p < 0.01, specificity 93% sensitivity 60%). In conclusion these results supports previous findings that AAS use causes a reduction in QTc, however, the specificity and sensitivity in our sample is lower than reported previously and precludes use as a screening tool.]]> Wed 07 Apr 2021 13:57:01 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11736 Wed 07 Apr 2021 13:57:01 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11739 Wed 07 Apr 2021 13:57:01 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11737 Wed 07 Apr 2021 13:57:01 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11738 Wed 07 Apr 2021 13:57:01 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11716 Wed 07 Apr 2021 13:57:00 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11726 Wed 07 Apr 2021 13:57:00 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11715 Wed 07 Apr 2021 13:57:00 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11712 Wed 07 Apr 2021 13:57:00 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11706 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11707 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11699 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11695 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11700 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11701 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11709 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11708 0.05).

Blood hormones were sampled pre- and post-intervention from an antecubital forearm vein and analysed using electrochemiluminescent immunoassay. Cardiorespiratory fitness ([Formula: see text]) was determined via indirect calorimetry during an incremental cycle test to volitional exhaustion. RESULTS: Analysis of variance (ANOVA) revealed a lack of significant change in any parameter amongst LE, whilst SED experienced a significant exercise-induced improvement in cardiorespiratory fitness and total testosterone (all p < 0.05). Concurrent increases in sex hormone-binding globulin (SHBG; p < 0.05) resulted in a lack of change to either bioavailable or calculated free testosterone (p > 0.05) amongst SED. CONCLUSIONS: Although resting levels of systemic total testosterone increased in response to 6 weeks of exercise training, increases in SHBG negated any potential relationship between calculated-free or bioavailable testosterone. These findings indicate that increases in bioavailable testosterone fraction are not required for cardiorespiratory fitness improvements in aging men.]]> Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11711 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11704 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11703 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11705 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11697 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11693 3 months (SA), bodybuilding controls (n = 8) (BC), and (n = 8) sedentary male controls (SC).

Results: A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = −0.87 to −1.38), followed by aerobic exercise (g = −0.51 to −1.02), and resistance exercise (g = −0.41 to −0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = −0.10, PrI = −2.23, 2.03), mind-body versus aerobic (g = −0.36, PrI = −2.69, 1.97), or mind-body versus resistance (g = −0.46, PrI = −2.75, 1.83). Conclusions: These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression. © 2019]]> Thu 25 Nov 2021 11:34:55 AEDT ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:17308 Thu 23 Feb 2023 11:41:26 AEDT ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13852 0.05, in both groups).

Results of this study suggest moderate-intensity aerobic exercise and HIIT lowers IL-6 (and possible hsCRP) in previously sedentary older men. Moreover, lifelong exercise is associated with reduced concentrations of some inflammatory biomarkers in older males, and therefore, physical activity, rather than age per se, is implicated in chronic low-grade inflammation. Moreover, physical inactivity-induced inflammation may be partly salvaged by short-term exercise training. © Copyright © 2021 Hayes, Herbert, Sculthorpe and Grace.]]> Mon 24 Jan 2022 12:58:13 AEDT ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:15186 Mon 23 Aug 2021 11:39:35 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:17733 0.929) and Cronbach’s Coefficient Alpha (CCA > 0.924) reliability for both the kinematic and temporal parameters.
