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.

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 ]]> Perspectives on Anabolic Androgenic Steroids (AAS) and doping in sport and health http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11807 Wed 07 Apr 2021 13:57:05 AEST ]]> Commercial golf glove effects on golf performance and forearm muscle activity http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11788 Wed 07 Apr 2021 13:57:04 AEST ]]> Electromyographic analyses of the erector spinae muscles during golf swings using four different clubs http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11794 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 ]]> The effects of a formal exercise training programme on salivary hormone concentrations and body composition in previously sedentary aging men http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11705 Wed 07 Apr 2021 13:56:59 AEST ]]> Utility of the hypertriglyceridemic waist phenotype in the cardiometabolic risk assessment of youth stratified by body mass index http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11673 /=90th percentile for age and gender with concomitant triglyceride concentrations >/=1.24 mmol L(-1) .

RESULTS: Normal weight participants with the HTWP had significantly higher levels of C-reactive protein 2.6 +/- 0.4 vs. 1.6 +/- 0.3 mg L(-1) (P < 0.05) and cardiometabolic risk scores (1.3 +/- 0.3 vs. -0.7 +/- 0.2 and 2.1 +/- 0.4 vs. -0.5 +/- 0.2; both P < 0.05) compared with those of a normal weight without the HTWP.

Similar associations were observed for BMI and WC. Both BMI-z and WHtR were fair predictors of increased cardiometabolic risk, although BMI-z demonstrated the best trade-off between sensitivity and specificity, 76.1% and 63.6%, compared with 68.1% and 65.5% for WHtR. Cross-validation analysis revealed that BMI-z and WHtR correctly classified 84% of individuals (kappa score = 0.671, 95% CI 0.55, 0.79). The sensitivity of the cut-points suggests that 89.3% of individuals were correctly classified as being at risk with only 10.7% misdiagnosed whereas the specificity of the cut-points indicated that 77.8% of individuals were correctly identified as being healthy with 22.2% of individuals incorrectly diagnosed as being at risk.
