Jump Height from Inertial Recordings : A Tutorial for a Sports Scientist
2019
Jump performance provides meaningful information both for sporting and clinical needs. Current state-of-the-art in jump performance assessment is laboratory-bound, however, out-of-the-laboratory methods are desirable. Therefore, the purposes of the present investigation were 1) to explore whether utilising a novel analytical approach minimises the bias between inertial recording unit (IMU)-based and jump mat-based jump height estimates, and 2) to provide a thorough tutorial for a sport scientist (see appendix) to facilitate standardisation of jump height estimation. Forty one women, men and boys aged 6 to 77 years-of-age completed three maximal counter movement jumps without arm swing, whic…
Intra- and inter-rater reliability of thoracic spine mobility and posture assessments in subjects with thoracic spine pain
2020
Abstract Background The thoracic spine (TS) has been neglected in the study of the spine despite its essential role in the stability and posture of the entire spinal complex. Therefore, there is an inevitable need to investigate the reproducibility of different thoracic spinal posture measures used in subjects with TS pain. Methods Thirty-two subjects (16 females and 16 males, mean age 39 years) were evaluated by two physiotherapists on the same day to gauge inter-rater reliability and on two consecutive days to gauge intra-rater reliability. TS posture was assessed by observation, and thoracic spine mobility was measured by manual assessment of segmental flexion and extension mobility in a…
Influence of low temperature on bronchodilatation induced by terbutaline administered by metered dose or dry powder inhalers in asthmatics.
2000
Low temperatures may affect dose delivery efficacy and clinical effectiveness of medication aerosols. In this study we examine the effect of cold ambient temperature on the bronchodilatation produced by terbutaline delivered from a chlorofluorocarbon pressurized metered dose inhaler (pMDI) compared to a multi-dose dry powder inhaler (DPI). Fourteen stable asthmatics were studied on two consecutive days. On day 1, after measuring FEV1 at room temperature (22 degrees C), each patient was randomized to receive 500 microg of terbutaline delivered from pMDI or DPI stored for 24 h at 22 degrees C with FEV1 recorded 20 min post-dose; then, patients were placed in a chamber at -10 degrees C, and af…
Effects of treadmill running and fatigue on impact acceleration in distance running
2014
The effects of treadmill running on impact acceleration were examined together with the interaction between running surface and runner's fatigue state. Twenty recreational runners (11 men and 9 women) ran overground and on a treadmill (at 4.0 m/s) before and after a fatigue protocol consisting of a 30-minute run at 85% of individual maximal aerobic speed. Impact accelerations were analysed using two lightweight capacitive uniaxial accelerometers. A two-way repeated-measure analysis of variance showed that, in the pre-fatigue condition, the treadmill running decreased head and tibial peak impact accelerations and impact rates (the rate of change of acceleration), but no significant differenc…
Insulin resistance and oxidative stress in familial combined hyperlipidemia.
2007
Oxidative stress is associated with atherosclerosis. Familial combined hyperlipidemia (FCH) is considered as a human model of primary dyslipidemia and atherosclerosis frequently associated with insulin resistance (IR), but there are few data on its possible relation to oxidative stress. The objective of this study was to evaluate oxidative stress status using different markers in subjects with FCH assessing its possible correlation with anthropometric parameters and IR. This was a cross-sectional study. A cohort of 40 FCH patients (20 with IR (HOMAor=3.2) and 20 without IR (HOMA3.2)), and 20 healthy volunteers were included, all of them non-diabetic, normotensive and non-smokers. We measure…
Increasing physical activity through an Internet-based motivational intervention supported by pedometers in a sample of sedentary students: A randomi…
2017
The aim of this study was to analyse the effect of an Internet-based motivational intervention (IMI) supported by pedometers (in comparison with IMI alone and non-intervention) on increasing daily steps and changing constructs related to physical activity (PA) in a sample of sedentary students.A randomised-controlled trial was conducted with 76 sedentary or low-active college students. The purpose of the IMI was to deliver information to increase motivation and set individualised PA goals. It involved a 3-week intervention and a 3-months follow-up.Objective measures were used to measure daily steps, and self-report questionnaires to assess different constructs related to PA.Results revealed…
Can different stages of leprosy treatment influence the profile of oral health? Oral status in leprosy
2018
Background The aim of study was to evaluate the oral health status, salivary flow and halitosis among individuals diagnosed with leprosy as compared with healthy subjects. Material and Methods A sample of 160 individuals was allocated into four groups, as follows: (G1) individuals with complete leprosy treatment; (G2) individuals diagnosed with leprosy and under multi-drug therapy; (G3) individuals diagnosed with leprosy not yet under treatment; and (G4) healthy individuals. Then individuals were submitted to periodontal clinical examination (visible plaque index, bleeding index, depth of probing and clinical attachment level); DMFT index (decayed-missing-filled teeth index); evaluation of …
Comparison of Peak Cough Flows Measured by Pneumotachograph and a Portable Peak Flow Meter
2004
To compare peak cough flows (PCF) obtained with a pneumotachograph (PCFp) with those measured using a portable peak flow meter (PCFm) in a population of healthy subjects and patients with neuromuscular disease.A total of 30 healthy subjects and 32 medically stable patients with neuromuscular diseases were studied. Using an oronasal mask connected, in a randomized order, to a pneumotachograph and to a portable peak flow meter, PCFp and PCFm were measured as every subject performed maximal cough efforts from total lung capacity.PCFp measurements were 377.70 +/-179.28 liters/min and PCFm measurements were 377.50 +/- 172.98 liters/min (not significant). The two measurements were correlated (r =…
Effects of ageing on motor unit activation patterns and reflex sensitivity in dynamic movements.
2009
Both contraction type and ageing may cause changes in H-reflex excitability. H reflex is partly affected by presynaptic inhibition that may also be an important factor in the control of MU activation. The purpose of the study was to examine age related changes in H-reflex excitability and motor unit activation patterns in dynamic and in isometric contractions. Ten younger (YOUNG) and 13 elderly (OLD) males performed isometric (ISO), concentric (CON) and eccentric (ECC) plantarflexions with submaximal activation levels (20% and 40% of maximal soleus surface EMG). Intramuscular EMG data was analyzed utilizing an intramuscular spike amplitude frequency histogram method. Average H/M ratio was a…
Noninvasive Determination of Anaerobic Threshold Based on the Heart Rate Deflection Point in Water Cycling
2015
This study compared heart rate (HR), oxygen uptake (V[Combining Dot Above]O2), percentage of maximal HR (%HRmax), percentage of maximal V[Combining Dot Above]O2, and cadence (Cad) related to the anaerobic threshold (AT) during a water cycling maximal test between heart rate deflection point (HRDP) and ventilatory (VT) methods. In addition, the correlations between both methods were assessed for all variables. The test was performed by 27 men in a cycle ergometer in an aquatic environment. The protocol started at a Cad of 100 b·min-1 for 3 minutes with subsequent increments of 15 b·min-1 every 2 minutes until exhaustion. A paired two-tailed Student's t-test was used to compare the variables …
