Relationship Between Functional Movement Screen and Some Athletic Abilities in Karate Athletes

In karate athletes, quality of movement and trunk control are important factors. Power output that is performed in short time requires functional movement capabilities. It’s quite important to know that which athletic abilities are related to functional movement. Due to this concern, the aim of the study was to examine relationship between functional movement screen (FMS) and some athletic abilities.20 male, 12 female karate athletes (Blue or higher belts; age: 16,06±0,9 years; training age: 7,5±1,1 years; weight: 63,06±11,6 kg; height: 171,9±6,1 cm) voluntarily participated in the study. Measurements have been taken on non-consecutive days in Functional Movement Screen (FMS) test battery, core stabilization test battery, back-leg extension isometric strength (BS), handgrip strength (HS), flexibility (S&R) and vertical jumping (SJ).The results showed that there is the significant relationship between FMS and S&R, SJ, core stabilization (p<0.01), and BS (p<0.05). There is no the significant correlation between HS. Due to the relationship between FMS Score and core stabilization, S&R, SJ and BS.It’s recommended practicing all these abilities to increase the quality of movement. Likewise, functional movement levels should be increased to perform better these athletic abilities

The acute effect of vibration applications on jumping performance

Recently, vibration has become very popular as a method of exercise and training and drawn attention of researchers. The aim of this study was to analyses the acute affect of vibration applications as a method of exercise and training on jumping performance. In this study experimental group consists of 25 subjects who are studying at Physical Education and Sports Department of Sakarya University (age 22.2±1.7 years, height 179.2±4.8 cm. body weight 71.5±9.0 kg). This study included a) vibration at density of 35 Hz (3x30 sec.) frequency  that result from  aerobic exercise that has low density and b) just  methods of aerobic exercise (without any vibration) that has  low density. Subjects have taken the tests of countermovement and squat jumping after 2 minutes of each application. All applications and tests have been done in nonconsecutive days in a random scheme. In statistical analysis Wilcoxon has been applied in nonparametric scheme. For counter movement jumping; height of jumping,  the difference between before and after  the application of vibration related to the point of peak power and average power has been found significiant (respectively, p&lt;0.05; p&lt;0.05; p&lt;0.01). In addition to this, no statistical difference was found for squat vertical jumping before and after the application of vibration related to the point of peak power and average power (respectively, p&gt;0.05; p&gt;0.05; p&gt;0.05). As a result, it is concluded that vibration that is applied at the range of 35 Hz frequency could increase the performance of acute countermovement jumping.

Acute effects of differing duration of static stretching on speed performance Farklı sürelerde uygulanan statik germenin sürat performansına akut etkisi

Abstract Purpose: The purpose of this study was to determine the acute effects of differing duration (15s, 30s, 45s) of static stretching on speed performance. Method: Twenty students in Physical Education and Sports (age 23.3 ± 2.0 years, height 175.7 ± 5.8 cm, weight 67.6 ± 8.6 kg) implemented 4 differing duration static stretching protocol on ​​noncontiguous days. After low intensity aerobic exercise subjects applied 15s static stretching (SG15), 30s static stretching (SG30), 45s static stretching (SG45) and low intensity aerobic exercise without any stretching application (KU). Subjects performed 20m sprint test after each stretching protocol. Differing duration of static stretching methods were compared by repeated measures ANOVA and post-hoc methods. Results: Differences between KU and SG15 (%5.1), KU and SG30 (%6.6) and KU and SG45 (%10.9) was significant (p&lt;0.001). In addition significant difference was observed between SG15 and SG45 (p&lt;0.032). Conclusion: The results of this study showed that static stretching application of lower extremities have negative impact on the 20m sprint performance. Longer sprint performances were observed as the duration of static stretching increases. These results indicate that static stretching applications were inadequate to prepare the athletes for the activities (such as sprinting) which require high power production. Özet Amaç: Bu çalışmada farklı sürelerde (15, 30 ve 45 sn) uygulanan statik germenin sürat performansına olan akut etkisinin incelenmesi amaçlanmıştır. Yöntem: Yirmi Beden Eğitimi ve Spor öğrencisi erkek sporcu (yaş 23,3 ± 2.0 yıl, boy 175,7 ± 5.8 cm, beden ağırlığı 67.6 ± 8.6 kg) birbirini izlemeyen günlerde 4 farklı protokolü uygulamışlardır. Bu araştırma düşük yoğunluklu aerobik egzersizi takiben, 15 sn süreli statik germe (SG15), 30 sn süreli statik germe (SG30), 45 sn süreli statik germe (SG45) ve sadece düşük yoğunluklu aerobik egzersiz (KU) (kontrol-hiç germe olmadan) yöntemlerinden oluşmaktaydı. Sporcular her protokolden sonra 20 m sürat testini gerçekleştirmişlerdir. Isınma yöntemleri tekrarlı ölçümlerde ANOVA ve post-hoc yöntemleri ile karşılaştırılmıştır. Bulgular: Sürat performansları açısından KU protokolü ile SG15 protokolü arasında % 5.1’ lik fark (p&lt;0.001), KU protokolü ile SG30 protokolü arasında % 6.6’ lık fark (p&lt;0.001) ve KU protokolü ile SG45 protokolü arasında % 10.9’ luk fark (p&lt;0.001) anlamlı bulunmuştur. Ayrıca SG15 protokolü ile SG45 protokolü arasında anlamlı fark (p&lt;0.032) bulunmuştur. Sonuç: Bu araştırmanın sonuçları, alt ekstremiteye yönelik uygulanan statik germe uygulamalarının sporcuların sürat performanslarını düşürdüğünü göstermektedir. Statik germenin süresi arttıkça sürat performansının düştüğü gözlenmiştir. Bu sonuçlar statik germe uygulamalarının, sporcuları yüksek güç üretimi gerektiren aktivitelere (sürat gibi) hazırlamak için yetersiz kaldıklarını göstermektedir. 

Effect of combination treatment of protocatechuic acid with 5-fluorouracil and oxaliplatin on colon cancer Caco-2 cell line

Among the most common antitumor drugs used in the treatment of colon cancer are 5-fluorouracil and oxaliplatin (5-FU and OXA). However, both these drugs have many side effects, and hence there is a need for new treatment\approach to reduce the side effects aas well as drug concentration. In this context, here, we investigated the effect of addition of protocatechuic acid (PCA) onto either monotherapies or combination therapies of 5-FU and OXA on the human colon cancer (Caco-2) cell line. In addition, we did evaluate the synergistic effect of PCA with 5-FU and OXA. Further, we determined the suppressive effects of different doses of PCA alone or in combination with 5-FU/OXA on cell proliferation after 24 and 48 hours. We identified a suppressive effect of PCA on cell viability at 48 h starting from the dose of 50 µM Matrix metalloproteinase-2 (MMP-2) and MMP-9 gene expression levels and apoptotic effects showed significant increases and decreases depending on the dose and time applied in the experimental groups. The highest synergistic activity was seen at 2:1 concentration of 5-FU+ PCA. Our findings indicate the presence of the cytotoxic and apoptotic effects of PCA in Caco-2 cells at 48 h, increasing with a dose- and time-dependent manner

Graded weakly 1-absorbing prime ideals

In this paper, we introduce and study graded weakly 1-absorbing prime ideals in graded commutative rings. Let $G$ be a group and $R$ be a $G$-graded commutative ring with a nonzero identity $1\neq0$. A proper graded ideal $P$ of $R$ is called a graded weakly 1-absorbing prime ideal if for each nonunits $x,y,z\in h(R)$ with $0\neq xyz\in P$, then either $xy\in P$ or $z\in P$. We give many properties and characterizations of graded weakly 1-absorbing prime ideals. Moreover, we investigate weakly 1-absorbing prime ideals under homomorphism, in factor ring, in rings of fractions, in idealization

The Acute Effects of Different Warm-up Protocols on Change of Direction and Reactive Speed Performance

The purpose of the study was to examine the acute effects of open and closed skill warmings on change of direction and reactive speed performance.113 high school students participated in the study voluntarily. The students were divided into three groups as general warming (GW), open skill warming (OSW) and closed skill warming (CSW). Reactive speed and change of direction test was performed after the general warming (GW), open skill warming (OSW), and closed skill warming (CSW) protocols were applied in our study. In this study, general warming protocol was designed as control application and other warming protocols were designed as experimental application.In terms of the change of direction performance, with general warming the difference between OSW (p> 0.01) and CSW (p> 0.01) was found significant. However, the difference between closed skill warming and open skill warming was not significant. The difference between general warming and open skill warming (p 0,097) and open skill warming (p> 0.0212) was not significant.In our study, in which we examined the acute effects of on and off skill warmings on different speeds and reactive speeds of different warm-up protocols, it is thought that if warming includes open and closed skills, both change of direction performance and reactive speed performance can be increased

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P &lt; 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
