The aim of this study was to investigate the effects of a short duration and low weekly frequency integrative program on sprint, agility and jump performance in elite youth soccer players.
Twenty-eight elite youth soccer players, members of two professional clubs, playing in the U19 developmental championship participated in this study. They were divided into 2 groups the intervention group (EG,n=15) and the control group (CG, n=13). The duration of the intervention program was 8 weeks with a frequency of twice per week. The performance of the participants in the 10 meters and 30 meters speed, countermovement jump (CMJ), squat jump (SJ) and agility (Illinois agility test, Arrowhead agility test) was measured at the beginning and the end of the 8-week study.
There was no statistically significant difference in any performance measured between the two groups.
The results of the present study indicate that the addition of allowing frequency and short duration training intervention program did not enhance the physical fitness indicators, in high-level young soccer players.

Growing investment and the increase in research in women's football has had a positive effect on the level of performance over the last 10 years. The present review aimed to examine the literature on the physical and physiological characteristics of female football players from 2010 to 2019 to reflect the recent changes in professionalism. Characteristics investigated include anthropometry, strength, speed, endurance, power, change of direction and repeated sprint ability. These characteristics are presented in relation to playing position, age and competition-level. Results revealed that goalkeepers (171 cm, 66 kg) and defenders (168 cm, 61 kg) were the tallest and had the greatest body mass, while attackers were the fastest players over 20 m (3.05 s) and 30 m (4.38 s) and midfielders had the highest endurance (55.4 mL∙kg-1∙min-1) (P less then 0.05). Characteristics tended to improve with age until full biological maturity around 17 to 18 years of age. Competition comparisons demonstrated international players have significantly greater speed, repeated sprint ability, power and endurance characteristics (P less then 0.05). By identifying influential factors, coaches may be able to optimize their training and physical assessment practices, to better expose players to the required stimulus to develop these characteristics considered crucial to improved performance.
It has been suggested that recovery mode may contribute to performance during high - intensity interval exercise. However, there is no consensus regarding the effects of active and passive recovery modes on subsequent performance. To compare the effect of active versus passive recovery on performance during repeated high - intensity interval exercise.
Two reviewers independently conducted a search using the PRISMA systematic approach in three electronic databases (PubMed, Scopus and Cochrane CENTRAL) searching for randomized controlled trials (RCTs) comparing the effects of recovery mode on performance (until February 2020).
Twenty - six studies were included for analysis (17 for power output, nine for repeated-sprint ability and two for distance covered). Four studies found higher mechanical performance for passive recovery compared with active recovery. Six out of nine studies reported faster sprinting performance with passive recovery compared to active recovery. DMOG research buy Two studies demonstrated that passive recovery resulted in a greater distance covered during intermittent sprint exercise.
This systematic review suggests that performing high - intensity interval exercise with passive recovery results in greater performance when compared with active recovery.

The aim of the study was to evaluate how muscular performances, balance and posture were influenced applying Occlusal Splints and Taopatch
8 (Tao Technologies Srls, Cittadella, Padua, Italy) devices in athletes.
Eighteen athletes, 7 females and 11 males, with an average age of 23.8 years, were included. Two devices were used 1) a customized soft occlusal splint to be applied to the lower ach; 2) nanotechnological devices based on carbon nanotubules and quantum dots (Taopatch
) positioned on C7 and xiphoid process. Four functional tests were performed surface electromyography (sEMG), kinesiography, the squat jump and counter movement jump and handgrip test. The tests were performed in the following order at the baseline (no treatments), and after having applied the bite alone, the occlusal splint and Taopatch
devices together and the Taopatch
devices alone.
The sEMG showed an increased maximum clenching voltage in respect of the baseline for all treatments that included the occlusal splint. The kinesiography showed an improvement of the movements of the occlusal muscles. The squat jump increased the height of 10-14 mm, the best results registered with the bite. The handgrip showed an increased strength, that was higher with the bite and the Taopatch
devices used alone (~5 lbs.).
The use of an occlusal splint and Taopatch
devices use alone or in conjunction immediately influenced strength and balance of the occlusal postural muscles.

Both mechanisms are currently termed radioactive iodine (RAI)-refractory (RAI-R) thyroid cancer but the first reflects unsuitability for I-131 therapy that can be evaluated in advance of treatment, whereas the other can only be identified post hoc. Management of both represents a considerable challenge in clinical practice as failure of I-131 therapy, the most effective treatment of metastatic thyroid cancer, is associated with a poor overall prognosis. The development of targeted therapies has shown substantial promise in the treatment of RAI-R thyroid cancer in progressive patients. Recent studies show that selective tyrosine kinase inhibitors (TKIs) targeting B-type rapidly accelerated fibrosarcoma kinase (BRAF) and mitogen-activated protein kinase (MEK) can be used as redifferentiation agents to re-induce RAI uptake, thereby (re)enabling I-131 therapy. The use of dosimetry prior- and post-TKI treatment can assist in quantifying RAI uptake and improve identification of patients that will benefit from I-131 therapy.
