The purpose of the study was to measure anthropometry, isometric force, balance, functional movement quality and asymmetries and peak oxygen uptake of prospective Rio 2016 Olympic Games Eventing horse riders (five males and two females: age 26-41 years, height 173.0 ±8.9 cm, weight 66.4 ±11.1 kg, BMI 22.0 ±1.8 kg·m-2, FEI ranking 33-409). Mean and maximal isometric of the hands were approximately 45 kg, and 50 kg, respectively. Total maximal isometric force of the lower limb resulted 372.6 kg for the extensor muscles, and approximately 58 kg for the adductor muscles. Mean composite functional movement score was 14.1, mean Bunkie score 3.4, Y-balance score 93.1 ± for the left side and 90.9 for the right one. V?O2peak values ranged between 2.4 and 4.2 l·min-1 and 46.8 and 59.7 ml·kg-1·min-1. The oldest and more experienced athletes had a greater postural control on the anterior direction. The athletes with a superior FEI ranking had a greater postural control. Subjects had high maximal isometric strength of the hands and lower limbs, good physical functions parameters, balance and maximal aerobic power and few muscular strength and balance asymmetries.

The 6-minute walking test (6MWT) is a simple assessment tool to evaluate exercise capacity. The result of the test is the distance that a subject can walk at a constant and normal pace within 6 minutes (6MWD) and reflects the aerobic/fitness performance related to walking function. Use of 6MWT has been relevant to assess exercise tolerance either in healthy children or in patients with, heart, lung and metabolic diseases. Our aim was to find 6MWT reference values in healthy Italian children. The 6MWT was performed in 5614 children aged 6–11 years recruited from primary Italian schools. Age related reference percentiles of the covered distance were gender-modeled. A linear and quadratic regression model was used to predict 6MWT performance. Males walked longer distances than females, respectively 598.8±83.9 m vs 592.1±77.6 m (p = 0.0016). According to the regression analysis, 6MWD was positively related to age, gender and height, while it was negatively related to body weight [(6MWD = -160.16 + 93.35× age (years) -4.05× age2 (years) +7.34× gender (m) +2.12× weight (kg) −2.50× height (cm)]. Reference values were established for the 6MWT in healthy children. The age related 6MWD percentiles provided a useful tool in the assessment of capacity in 6–11 year children, in fact they may be helpful to evaluate the effect of a given treatment or rehabilitation program and represent a feasible measure as to prevention within the primary school context. It was found a substantial difference from other countries for 6mwd values. In our study, factors such as age, weight and height were relevant for the prediction of 6MWD, similarly to other studies. Therefore, these variables should be taken into account in context of exercise performance. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to compare objective and subjective assessments of physical activity (PA) in patients with anorexia nervosa and its effect on treatment outcome. Methods: Both Actiheart (AH) and International Physical Activity Questionnaire (IPAQ) were used to assess PA in 52 female patients with anorexia nervosa during the first week of inpatient treatment. Results: No correspondence between PA estimated by IPAQ, which had a tendency to underestimate PA, and that measured using AH emerged. However, a significant association was found between the change in Eating Disorder Examination global score at the end of the treatment and light PA measured by AH (beta = −0.12, t = −2.44, P = 0.019), but not that estimated by IPAQ. Conclusions: PA in patients with anorexia nervosa is underestimated by subjective assessment when compared with objective measurement. Only time spent in light PA, assessed objectively with AH, showed a negative association with improvement in eating disorder psychopathology. [ABSTRACT FROM AUTHOR]
