Research on the acute responses to exercise in pregnancy is scarce, especially for women affected by gestational diabetes mellitus (GDM). The aim of this study was to investigate responses to a single bout of exercise performed multiple times throughout the pregnacy in women diagnosed with GDM. Data from 18 pregnant women (aged: 32.8 ± 3.8) diagnosed with GDM, treated with diet only, were analysed. Participants' pre-pregnancy body mass index was 24.4 ± 4.9 kg/m2 , 50% of them were nullipaorus, and 50% of the sample regularly exercised before the pregnany...

Student-athletes who strive for success in high level sports while pursuing upper secondary education may be prone to sport and school burnout. The present study examined the co-developmental dynamic of sport and school burnout in Finnish adolescent student-athletes (N time 1 = 391; N time 2 = 373) across the first year of upper secondary school by using cross-lagged structural equation modeling (SEM). Furthermore, we used sport and school-related achievement goals as predictors of sport and school burnout, namely, sport and school-related exhaustion, cynicism, and feelings of inadequacy...

Sedentary time (ST) and moderate to vigorous physical activity (MVPA) are associated with cardiometabolic health. Cardiorespiratory fitness (CRF) is also implicated but often overlooked in health recommendations. This study assessed the relationships between ST, MVPA, CRF and cardiometabolic health in highly active older individuals. 125 healthy amateur cyclists aged 55 to 79 years had their ST and MVPA levels assessed by actigraphy over a 7 day period. CRF was assessed using a maximal effort cycle ergometry test to determine VO2max with results normalised to both body mass and fat free mass measured by DXA...

Athletic groin pain (AGP) is a common injury prevalent in field sports. One biomechanical measure that may be of importance for injury risk is stiffness. To date however, stiffness has not been examined in AGP. The primary aim was to determine if AGP affects vertical and joint stiffness and if so, whether successful rehabilitation is associated with a change in stiffness. Sixty-five male patients with AGP and fifty male controls were recruited to this study. Assessment included a biomechanical examination of stiffness during a lateral hurdle hop test...

With advances in technology, scientists are now able to more accurately measure elbow displacement changes during the cricket bowling action. This has led to the realisation that the majority of bowlers undergo some degree of elbow extension during the forward swing phase of bowling. Consequently, the International Cricket Council were obliged to revise the once zero tolerance for elbow extension threshold to a 15° range. However, it is still not understood if bowling with greater than 15° of elbow extension aids performance or alters other kinematic movements...

Adaptations to 6 weeks of supervised hamstring stretching training and its potential impact on symptoms of eccentric exercise-induced muscle damage (EIMD) were studied in 10 young, untrained men with limited hamstrings flexibility. Participants performed unilateral flexibility training (experimental leg; EL) on an isokinetic dynamometer while the contralateral limb acted as control (CL). Hip range of motion (ROM), passive, isometric and concentric torques, active optimum angle, and biceps femoris and semitendinosus muscle thickness and ultrasound echo intensity were assessed both before and after the training...

In this study, we hypothesized that the recordings of multi-channel mechanomyography (MMG) of the upper trapezius muscle would reveal spatially-dependent manifestations in presence of delayed onset muscle soreness occurring 24-h after eccentric exercise (ECC). Sixteen participants performed high intensity eccentric exercises (5 sets of 10 eccentric contractions at 100% of max elevation force) targeting the upper trapezius on their dominant side. Twelve accelerometers were attached to record MMG activity during submaximal exercise consisting of static and dynamic arm flexion and abduction...

Comprehensive investigations into the mortality outcomes of elite athletes can assist in decoding risk factors of premature mortality and provide avenues for exploring human health through engagement in sport. As such, the purpose of this study was to comprehensively examine lifespan trends of athletes from the four major sports in North America: Major League Baseball (MLB), National Basketball Association (NBA), National Football League (NFL) and National Hockey League (NHL). We hypothesized that proportional death rates would be similar across the four sports, when standardizing the data by debut years...

The mechanisms that regulate bone blood flow (BBF) in humans are largely unknown. Animal studies suggest that nitric oxide (NO) could be involved and in the present study we investigated the effects of inhibition of nitric oxide synthase (NOS) alone and in combination with inhibition of cyclooxygenase (COX) enzyme, thus prostaglandin (PG) synthesis on femoral bone marrow blood flow by positron emission tomography in healthy young men at rest and during one leg dynamic exercise. In an additional group of healthy men, the role of adenosine (ADO) in the regulation of BBF during exercise was investigated by use of an adenosine receptor blocker (aminophylline)...

This study describes the prevalence, incidence density, severity, and nature of injuries in elite field hockey players over the Dutch 2015-2016 season. Eighty players answered a baseline questionnaire and were subsequently followed-up every 2 weeks to report the hours spent on training/competition and experienced injuries, which were registered using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems. Of the 74 players included in the analysis, 52 (70%) reported 112 injuries. Eighty-seven injuries (78%) received medical attention, and 56 (50%) led to training/competition time loss...

The experiment investigated the progressions of the qualitative and quantitative changes in the movement dynamics of learning the ski-simulator as a function of prior related task experience. The focus was the differential time scales of change in the candidate collective variable, neuro-muscular synergies, joint motions and task outcome as a function of learning over 7 days of practice. Half of the novice participants revealed in day 1 a transition of in-phase to anti-phase coupling of center of mass (CoM) - platform motion whereas the remaining novices and experienced group all produced on the first trial an anti-phase CoM-platform coupling...

Children change their body size, shape and gross motor coordination (GMC) as they grow. Further, GMC is expected to link to changes in children's body size, physical activity (PA) and physical fitness (PF). The objective was to model GMC changes in children followed longitudinally and to investigate associations between these changes and PA and PF levels. A total of 245 children (122 girls) were observed at 6 years of age and followed annually until 9 years. A sequence of allometric models were fitted, i.e...

We compared the effects of cycling and running exercise on hemorheological and hematological properties, as well as eryptosis markers. Seven endurance-trained subjects randomly performed a progressive and maximal exercise test on a cycle ergometer and a treadmill. Blood was sampled at rest and at the end of the exercise to analyze hematological and blood rheological parameters including hematocrit (Hct), red blood cell (RBC) deformability, aggregation and blood viscosity. Hemoglobin saturation (SpO2), blood lactate and glucose levels were also monitored...

The purpose of this study was to examine the propulsion asymmetries of wheelchair athletes whilst sprinting on an instrumented, dual-roller ergometer system. Eighteen experienced wheelchair rugby players (8 low-point (LP) (class ≤1.5) and 10 high-point (HP) (class ≥2.0)) performed a 15s sprint in their sports wheelchair on the instrumented ergometer. Asymmetry was defined as the difference in distance and power output (PO) between left and right sides when the best side reached 28m. Propulsion techniques were quantified based on torque and velocity data...

BACKGROUND: Peak oxygen uptake (VO2peak) is commonly indexed by total body weight (TBW) to determine cardiopulmonary fitness (CPF). This approach may lead to misinterpretation, particularly in obese subjects. We investigated the normalization of VO2peak by different body composition markers. METHODS: We analyzed combined data of 3,848 subjects (1,914 women; 49.7%), aged 20-90, from two independent cohorts of the population-based Study of Health in Pomerania (SHIP-2 and SHIP-TREND)...
