RESUMO
OBJECTIVES: The aim of the current study was to investigate the impact of individualised versus standardised combined endurance and resistance training on the fitness-fatness index in physically inactive adults. DESIGN: Randomised controlled trial. METHODS: Fifty-four participants aged 21-55â¯years were randomised into three groups; 1) non-exercise control (nâ¯=â¯18), 2) standardised moderate-intensity continuous training (nâ¯=â¯18), or 3) individualised moderate-intensity continuous trainingâ¯+â¯high-intensity interval training (nâ¯=â¯18). The fitness-fatness index was calculated by dividing cardiorespiratory fitness (expressed as metabolic equivalents) by the waist-to-height ratio. Participants were classified as likely responders to the intervention if a change of ≥1 fitness-fatness index unit was achieved. RESULTS: The individualised group showed the greatest fitness-fatness index improvement (between group difference pâ¯<â¯0.001), with 100â¯% of this group classified as likely responders, compared to the standardised (68â¯%) and non-exercise control (0â¯%) groups. CONCLUSIONS: An individualised, threshold-based exercise programme may produce more favourable changes in the fitness-fatness index than a standardised exercise programme.

BACKGROUND: Endometriosis is a debilitating chronic condition that is commonly associated with chronic pelvic pain, affecting approximately 10% of women of reproductive age worldwide. The general principle of pain management in this population involves both pharmacological and surgical interventions. There is also increasing interest in the use of exercise as an alternative non-pharmacological analgesic, but adherence and accessibility to face-to-face exercise-delivery modalities are poor. This study aims to determine the immediate impact of a single session of 'supervised' telehealth-delivered exercise compared to 'self-managed' virtual reality (VR)-delivered exercise on pelvic pain associated with endometriosis. METHODS: Twenty-two women experiencing pelvic pain due to endometriosis were included and randomized into three groups: (i) VR-delivered exercise group (n = 8); (ii) telehealth-delivered exercise group (n = 8); and (iii) control group (n = 6). The visual analogue scale (VAS) was used to assess the severity of pelvic pain. RESULTS: There was no statistically significant between-group difference (p = 0.45) in the participants' pain score following a single session of the study interventions (VR or telehealth) or the control. However, a 'medium-to-large' group x time interaction effect (η2 = 0.10) was detected, indicating a more favorable pain score change following a single session of telehealth- (pre-post ∆: +10 ± 12 mm) and VR-delivered exercise (pre-post ∆: +9 ± 24 mm) compared to the control group (pre-post ∆: +16 ± 12 mm). CONCLUSIONS: Our study suggests that a single bout of a 'self-managed' VR-delivered exercise may be as efficacious as a single session of 'supervised' telehealth-delivered exercise in providing immediate relief from pelvic pain associated with endometriosis.

A poor Fitness Fatness Index (FFI) is associated with type 2 diabetes incidence, other chronic conditions (Alzheimer's, cancer, and cardiovascular disease) and all-cause mortality. Recent investigations have proposed that an individualised exercise prescription based on ventilatory thresholds is more effective than a standardised prescription in improving cardiorespiratory fitness (CRF), a key mediator of FFI. Thus, the aim of the current study was to determine the effectiveness of individualised versus standardised exercise prescription on FFI in sedentary adults. Thirty-eight sedentary individuals were randomised to 12-weeks of: (1) individualised exercise training using ventilatory thresholds (n = 19) or (2) standardised exercise training using a percentage of heart rate reserve (n = 19). A convenience sample was also recruited as a control group (n=8). Participants completed CRF exercise training three days per week, for 12-weeks on a motorised treadmill. FFI was calculated as CRF in metabolic equivalents (METs), divided by fatness determined by waist to height ratio (WtHR). A graded exercise test was used to measure CRF, and anthropometric measures (height and waist circumference) were assessed to ascertain WtHR. There was a difference in FFI change between study groups, whilst controlling for baseline FFI, F (2, 42) = 19.382 p < .001, partial η2 = 0.480. The magnitude of FFI increase from baseline was significantly higher in the individualised (+15%) compared to the standardised (+10%) (p = 0.028) and control group (+4%) (p = <.001). The main finding of the present study is that individualised exercise prescription had the greatest effect on improving FFI in sedentary adults compared to a standardised prescription. Therefore, an individualised based exercise prescription should be considered a viable and practical method of improving FFI in sedentary adults.

PURPOSE: To evaluate the ability to control vectors in the technique of transportation osteogenesis using 4 principles. PATIENTS AND METHODS: Sixteen defects measuring approximately 30-180 mm were retrospectively evaluated. Vector control was attempted using a single or combination of the following principles: multiple linear vectors, exaggerated linear distraction ("sausage effect"), braced guided distraction, and reorientation osteotomies. Observations were made regarding the ability to create the desired vectors. Angular deviation from desired vectors was determined and recorded numerically by evaluating either submental vertex or occlusal radiographs, stereolithographic models, or digital radiographs. Radiographic evaluation of symmetry alone was not used to determine the desired vector because a more laterally displaced segment was desirable to maintain favorable facial balance when soft tissue deficiency was pronounced. A subjective evaluation scale was developed to supplement the numerical values. RESULTS: Vector control primarily required the use of 2 or more principles. The most common combination was that of exaggerated linear distraction and reorientation osteotomy. CONCLUSION: The use of multiple linear vectors, exaggerated linear distraction ("sausage effect"), reorientation osteotomies, and braced guided distraction greatly assisted the operator in achieving the goal of symmetrical reconstruction. Transportation osteogenesis may be considered an effective tool in the box to reconstruct patients. In cases in which vector control is achieved, the advantages of diminishing the volume of bone graft required or achieving final bony reconstruction can outweigh the disadvantages of the technique.
