Many position stands and review papers have refuted the myths associated with resistance training (RT) in children adolescents. With proper methods, RT for adolescents can be relatively safe improve overall health. The objective of this paper is to highlight research provide recommendations aspects that not been extensively reported pediatric literature. In addition well-documented increases muscular strength endurance, has used function patients cystic fibrosis cerebral palsy, as well burn...
To assess the prevalence of delayed menarche and abnormal menstrual patterns, as well association status with physical training in elite rhythmic gymnasts from Greece Canada.Fifteen Greek (mean (SEM) age 14.5 (0.2) years) 30 Canadian 14.7 (0.4) were surveyed for at menarche, frequency, profile, measured height, weight, percentage body fat (%BF). Seventy eight healthy adolescents served country specific non-active controls: 38 non-athletes (0.1) 40 14.2 years).Of gymnasts, 79% had not yet...
It is not known whether children with Developmental Coordination Disorder (DCD) have lower cardiorespiratory fitness (CRF) than without the disorder, or this relationship varies by age and gender. These issues are examined using a cross-sectional assessment of 9-14 years (N = 549). Participants were screened for DCD short form Bruininks-Oseretsky Test Motor Proficiency (BOTMP-SF). A BOTMP-SF age-adjusted standard score at below 10th percentile rank on was required to classify diagnosis...
Low-impact, high-intensity interval exercise (HIE) was used to investigate the postexercise response in bone turnover markers and cytokines.Twenty-three recreationally active males (21.8 ± 2.4 yr) performed one HIE bout on a cycle ergometer at 90% maximum workload. The total duration of 12 min included six 1-min intervals separated by rest intervals. Blood samples were collected before exercise, 5 min, 1 h, 24 h after analyzed for serum levels anti- pro-inflammatory cytokines (interleukin 10...
Background: Physical activity (PA) declines during early adulthood with higher rates of inactivity in university students. The authors aimed to examine the frequency, intensity, time, type PA, and barriers PA participation Canadian students first year university. Methods: Questionnaires assessing variables were administered 301 first-year at beginning end academic year. Results: decreased over a Males engaged more vigorous minutes, strength training, organized sports than females (P < .05)....
Muscle strength and activation were compared in boys men during maximal voluntary elbow flexion extension contractions. Peak torque, peak rate of torque development (dτ/dτ max ), muscle activation, electromechanical delay (EMD) measured 15 (aged 9.7 ± 1.6 years) 16 22.1 2.8 years). During flexion, was significantly lower than (19.5 5.8 vs. 68.5 11.0 Nm, respectively; p < 0.05), even when controlling for upper-arm cross-sectional area (CSA), electromyography activity. Boys also exhibited a...
Evidence suggests that athletes competing in team sports do not follow dietary recommendations. However, only few studies have investigated energy needs and supplement use adolescent athletes, whether they are meeting their requirements. This observational study examined expenditure, intake, of nutritional supplements 58 (14–17 years old) volleyball (15 males, 43 females) age-matched nonathletic controls (13 45 females). Participants completed an online survey including questions on...
Genome sequencing (GS) is a powerful test for the diagnosis of rare genetic disorders. Although GS can enumerate most non-coding variation, determining which variants are disease-causing challenging. RNA (RNA-seq) has emerged as an important tool to help address this issue, but its diagnostic utility remains understudied, and added value trio design unknown. We performed plus RNA-seq from blood using automated clinical-grade high-throughput platform on 97 individuals 39 families where...
Non-small cell lung cancer (NSCLC) accounts for 85% of all cases, and the most cancer-related deaths. The survival pathway Akt, its downstream effectors, mammalian target rapamycin (mTOR) ribosomal protein S6 kinase (p70 S6K), Ras-extracellular signal-regulated (Erk1/2) pathways are activated in leading to growth. Thus, approaches that inhibit these signaling molecules may prove useful fight against cancer. Exercise is associated with health benefits a limited number studies indicate serum...
This study examined potential exercise-induced changes in sclerostin and bone turnover markers young women following two modes of high intensity interval exercise that involve impact (running) or no-impact (cycling). Healthy, recreationally active, females (n=20; 22.5±2.7 years) performed trials random order: running (HIIR) on a treadmill cycling (HIIC) cycle ergometer. Trials consisted eight 1 min intervals at ≥90% maximal heart rate, separated by passive recovery intervals. Blood samples...
Children have lower size-normalised maximal voluntary force, speed, and power than adults. It has been hypothesised that these other age-related performance differences are due to lesser type-II motor-unit utilisation in children. This should be manifested as slower force kinetics explosive muscle contractions. The purpose of this study was investigate the nature child-adult force-kinetics whether latter could support hypothesis. Untrained boys (n = 20) men (10.1 ± 1.3 22.9 4.4 years,...
