European Resuscitation Council Guidelines for Resuscitation 2015
2015
Summary of changes since 2010 Guidelines The main changes in the ERC Guidelines 2015 in comparison with the Guidelines 20101are summarised below:Special causes•Survival after an asphyxia-induced cardiac arrest is rare and survivors often have severe neurological impairment. During CPR, early effective ventilation of the lungs with supplementary oxy-gen is essential.•A high degree of clinical suspicion and aggressive treatment can prevent cardiac arrest from electrolyte abnormalities. The new algorithm provides clinical guidance to emergency treatment of life-threatening hyperkalaemia.•Hypothermic patients without signs of cardiac instability(systolic blood pressure ≥90 mmHg, absence of vent…
Do Running and Strength Exercises Reduce Daily Muscle Inactivity Time?
2016
Understanding how a specific exercise changes daily activity patterns is important when designing physical activity interventions. We examined the effects of strength and interval running exercise sessions on daily activity patterns using recordings of quadriceps and hamstring muscle electromyographic (EMG) activity and inactivity. Five male and five female subjects taking part in a 10-week training programme containing both strength and interval running training sessions were measured for daily muscle EMG activities during three days: on a strength day, an interval running day, and a day without exercise. EMG was measured using textile electrodes embedded into sport shorts that were worn 9…
Increased susceptibility to lipid peroxidation in skeletal muscles of dystrophic hamsters.
1989
The results showed that the total content of lipids, which could be peroxidized with Fe(2 +)/ascorbate stimulation in vitro, was 45.4% and 53.7% higher than normal in the dystrophic hamster muscle at the age of 1 and 3 months, respectively. Correspondingly, the susceptibility to lipid peroxidation (stimulated by ADP-chelated iron at 37 degrees C) was 38.6-74.3% higher in dystrophic muscles. The increases were not related to necrotic lesions and inflammation observed. The activities of glucose-6-phosphate dehydrogenase, glutathione reductase, thioredoxin reductase and catalase were increased in dystrophic muscles but those of superoxide dismutases and glutathione peroxidase were unaffected.
Validity, Reliability, and Sensitivity to Change of DiCI for the Strength Measurement of Knee and Hip Muscles
2020
Many professionals use the handheld dynamometers (HHDs) to assess isometric strength. This study aimed to evaluate the validity, reliability, and sensitivity to change of a DiCI (a new HHD) for the...
Activation and torque deficits in ACL-reconstructed patients 4 months post-operative
2001
This study compares knee extension and flexion torques and electromyographic (EMG) activity of normal and anterior cruciate ligament (ACL)-reconstructed knees during maximal unilateral isometric and isokinetic tests performed 4–5 months after ACL reconstruction. The subjects consisted of 3 age- and activity-matched groups of 6 subjects: a healthy control group (Ctrl) and 2 groups of patients, with Kenneth-Jones technique using autologous patellar-ligament graft (KJ group) and autologous graft from the semitendinosus tendon (ST group). When compared to the Ctrl group values, each patient group had significant bilateral extension torque deficits in isometric and at slow velocity concentric co…
REGIONAL DIFFERENCES IN BICEPS FEMORIS FASCICLE LENGTH AND PENNATION ANGLE AFTER A SIMULATED SOCCER MATCH
2017
Background Hamstring Strain Injuries (HSIs) represent 12% of all injuries in soccer players, and their incidence has increased in recent years. Between 53%-84% of HSIs involve the Biceps femoris muscle (BF). Recent studies have shown that soccer players with shorter BF fascicle length (FL) suffer more HSIs and exhibit regional differences in FL and pennation angle (PA) along BF. It is unclear whether there is any regional difference in the degree of change of these parameters after a soccer match. Objective Describe changes in BF muscle architecture after a simulated soccer match. Design Controlled laboratory study. Pre and Post single session. Setting Laboratory. Amateur Level. Participant…
AB0929 Balance in fibromyalgia is not related with lower limb strength
2017
Background Postural control, that depends on many sensory contributors and motor skills, is altered in people with fibromyalgia (FM) 1–3. Knowing those contributors that could be impaired in this population is important to design an appropriate balance therapy. Objectives Due to the fact that people with FM use to present a strength loss 7, our main goal was to explore the relation between postural control and lower limb strength in this population. Further, the sensory inputs contributors to the postural control were assessed. Methods A cross-sectional study was conducted in a sample of 40 FM patients. A force platform was used to assess postural control under five bipedal conditions: i) e…
Children’s physical activity and sedentary time compared using assessments of accelerometry counts and muscle activity level
2018
Background This research compared accelerometry (ACC)-derived and muscle electromyography (EMG)-based estimates of physical activity (PA) and sedentary time in typical PA tasks and during the daily lives of children. Methods Data was included from two exploratory studies. In Study I, 6–7-year-old children (n = 11, 64% girls) were assessed for eight PA tasks (walking, stair negotiation, climbing, crawling, swinging, balancing, trampoline jumping and a game of tag). In Study II, 7–9-year-old children (n = 14, 38% girls) were assessed for six PA tasks (walking, sitting, static squat, single leg hops, jump for height and standing long jump), and daily PA during one day with and one day without…
Multifactorial individualised programme for hamstring muscle injury risk reduction in professional football: protocol for a prospective cohort study
2020
IntroductionHamstring muscle injuries (HMI) continue to plague professional football. Several scientific publications have encouraged a multifactorial approach; however, no multifactorial HMI risk reduction studies have been conducted in professional football. Furthermore, individualisation of HMI management programmes has only been researched in a rehabilitation setting. Therefore, this study aims to determine if aspecificmultifactorial and individualised programme can reduce HMI occurrence in professional football.Methods and analysisWe conducted a prospective cohort study over two seasons within the Finnish Premier League and compare the amount of HMI sustained during a control season to…
Isokinetic Profile of Elite Serbian Female Judoists
2021
Elite judo athletes undergo vigorous training to achieve outstanding results. In pursuit of achieving competitive success, the occurrence of injuries amongst judo athletes is not rare. The study aimed to perform a knee flexors and extensors isokinetic torque analysis in elite female judo athletes. Fifty-eight elite female judo athletes of the Serbian national team (21.02 ± 3.11 years
