Authors: da Silva Rubens A. , Larivière Christian , Plamondon André , Arsenault A. Bertrand , Nadeau Sylvie
Published: October 2018

The purpose of this study was to examine the effect of pelvic stabilization and lower-limb configuration on trunk extension strength and to test whether sex modify these effects. Twenty-two healthy volunteers (11 women and 11 men: SEX factor), age range 20–55 years participated in this study. Two isometric maximal voluntary contractions (MVCs) were performed in extension and the moment was calculated relative to L5/S1, for each of six experimental conditions. Two different positions were tested (POSITION factor): I) seated position (knees at 90°) and II) semi-sitting position (knees at 45°). In each POSITION, three pelvic stabilization conditions were tested(STABILIZATION factor): (1) unrestrained (control condition), (2) partially restrained (posteriorly) and (3) totally restrained (posteriorly and anteriorly). No significant main effects (p> 0.05) and no double and triple(SEX × STABILIZATION × POSITION) interaction reached statistical significance. Consequently, maximal trunk extension moment can be achieved with the use of various stabilization and positioning modalities, at least when the same apparatus allows such flexibility, and this as much in women as in men subjects. These results have implications for the assessment of trunk extension strength during pre- and post-training regiments during a rehabilitation program for strengthening of back muscles in patients with low back pain.

Published: October 2018

The aim of this study was to assess how much risk a resistance exercise can provide to individuals who have distinguished hyperCKemia response. Twenty-three healthy men performed an exercise protocol, during which 4 sets of biceps curl were performed at 85% of 1 repetition maximum (1RM). Each bout was performed to voluntary fatigue and the workout volume completed was calculated. Subjects provided blood samples prior, and at 24, and 48 h following exercise to evaluate serum creatine kinase (CK) activity. Based on serum CK activity responses the subjects were separated into two groups called: Normal Responders (NR) or High Responders (HR). A great interindividual variability in serum CK activity following exercise and a significant difference between NR and HR were observed. The workout volume demonstrated a significant reduction along sets but without difference between NR and HR. Our main finding was the great inter-individual variability in serum CK activity that is seen even when using a single exercise performed on a the day-to-day basis.

Authors: Meamarbashi Abbas , Abedini Farhad
Published: October 2018

Purslane is the richest vegetable source of omega-3 fatty acids and antioxidant nutrients. This is the first attempt to elucidate the possible effects of Purslane extract on muscle soreness. To examine the preventive effects of Purslane extract on delayed muscle soreness (DOMS) following one session eccentric exercise, twenty healthy non-athlete students were randomly assigned to the experimental and control groups. Experimental group received Purslane extract (n=10), 1200 mg/day from 72 hours before training until 48 hours after training. One session bench-stepping exercise performed to induce DOMS. Serum LDH, CK, Cortisol, IgA, Sodium and Potassium, maximal knee extension isometric force, thigh circumference, knee range of motion, and pain perception were measured 72 hours before exercise, immediately post, 24 and 48 hours after exercise. Serum concentration of LDH and Cortisol in 24 and 48 h after exercise exhibited a significant difference between control and experimental groups (P< 0.05). Serum CK was significantly lower after 48 h (P< 0.001). IgA has shown lower concentration immediately post, 24 and 48 h after exercise(P< 0.01). The level of pain perception was significantly lower in experimental group after 48 hours (P< 0.005). The right knee range of motion and maximal isometric force were significantly lower in the experimental group after 48 h (P ⩽ 0.05). These findings suggest that Purslane extracts reduced the biochemical and clinical variables of DOMS and it can be speculated that Purslane extracts is effective in prevention of DOMS.

Authors: Coburn Jared W. , Malek Moh H. , Housh Terry J. , Johnson Glen O. , Beck Travis W.
Published: October 2018

Background and objective: The purpose of this study was to compare an accelerometer (ACC) and a piezoelectric contact sensor (PEC) for the measurement of mechanomyographic (MMG) signals during submaximal to maximal isometric muscle actions of the vastus medialis.

Materials and methods: Following the determination of maximal isometric strength (MVC), eight subjects (20.4 ± 1.3 years) performed isometric muscle actions at 10 to 90% isometric MVC in random order. An ACC and PEC were used to simultaneously record the MMG signal.

Results: For the composite data, there were linear increases in normalized MMG amplitude for both the ACC(r ^{2} = 0.930) and PEC (r ^{2} = 0.875), with no difference in slope coefficients (p > 0.05). Similarly, there were linear increases in MMG mean power frequency (MPF) for the ACC (r ^{2} = 0.957) and PEC (r ^{2} = 0.982), with no difference in slope coefficients (p > 0.05). Analysis of individual subject data revealed there were no significant differences in slope coefficients between sensors for MMG amplitude or MPF for any subject with the exception of a significant difference (p < 0.05) for MMG MPF for one subject. In addition, there were no significant (p > 0.05) mean differences between the ACC and PEC for normalized MMG amplitude or MPF.

Conclusion: These results indicated that the ACC and PEC provide comparable information regarding MMG amplitude and MPF vs. isometric torque relationships of the vastus medialis.

Authors: Secchi Leonardo L. B. , Muratt Mavi Diehl , Ciolac Emmanuel G. , Greve Júlia M. D.
Published: October 2018

Objective: To compare knee extension-flexion isokinetic performance between elite swimmers of simultaneous (SS – butterfly and breaststroke) and alternated swimming (AS – front crawl and backstroke) styles.

Method: Nineteen short distance elite swimmers (50 m, 100 m and 200 m events), divided into SS (n=7; 23.3 ± 5.6 years) and AS (n=12; 22.6 ± 1.4 years) were tested for knee extension-flexion isokinetic strength at 60°/s (4 repetitions) and endurance at 300°/s (30 repetitions).

Results: There were no significant differences between groups or legs for concentric knee extension and flexion variables. However, the agonist/antagonist (HQ) ratio was lower (p=0.032) in AS than SS group for both legs.

Conclusion: These results indicate the need for training programs to improve strength balance between hamstrings and quadriceps muscles in short distance elite swimmers.

Published: October 2018

The aim of this study was to examine the effect of Nordic walking on upper extremity strength and the level of lymphoedema in women following treatment for breast cancer (BC). A group of 38 women with treated BC were assigned to two groups: a study group of 23 women taking part in 8 weeks of Nordic walking and a control group of 15 women. Each participant was assessed for bilateral muscle strength using an upper limb push-pull attachment. Circumference measurement served for determination of the volume of the lymphoedema.

In women after the surgical procedure on the right side statistically significant changes in the strength of pushing motion of both the right and the left were observed. In women after the surgical procedure on the left side these values were statistically significant only for the left extremity. No significant changes were demonstrated for the treated side; we did not record either the occurrence or the intensification of lymphoedema in women after BC treatment. So, Nordic walking can be considered as safe form of rehabilitation for this group of patients.
Distribution and progression of muscle weakness in two cases of polymyositis
Authors: Bohannon Richard W. , Dvir Zeevi
Published: October 2018

The strength profile of two patients suffering from polymyositis is presented. In the first patient, 6 muscle actions (shoulder abduction, elbow flexion, grip, hip flexion, knee extension, ankle dorsiflexion) were measured bilaterally in 3 ways including a modification of the Stroke Impact Scale, manual muscle testing and hand-held dynamometry. All methods indicated considerable weakness, including that of the distal muscles. In the second patient, concentric and eccentric strength of the quadriceps was measured 6 times over a period of 13 years. The findings strongly demonstrated a progressive increase in knee extension weakness. The results support the notion that polymyositis affects distal as well as proximal muscles and that the weakness is fully appreciated when the strength of the muscles involved is quantitatively measured using dynamometry.

Authors: Mota Nuno , Ribeiro Fernando
Published: October 2018

This study aimed to investigate the association between shoulder proprioception and shoulder rotators strength in water polo players. Twenty male water polo players aged 20.2 ± 2.3y participated in the study. Shoulder proprioception was evaluated by assessing joint position sense (JPS) at 30° of external rotation and at 30° of internal rotation. Shoulder external and internal rotators concentric and eccentric muscle strength was evaluated isokinetically at 120°/s. JPS acuity at 30° of external rotation [4.7(3.5°)] was similar to that observed at 30° of internal rotation [4.0(5.3°)]. The external/internal rotators strength ratio were 0.67 (0.23) and 0.66 (0.18), respectively for concentric and eccentric efforts while the dynamic control ratio was 0.69 [0.16]. Negative and significant correlations were found between relative error at 30° of external rotation and concentric and eccentric external rotators PT: r = −0.445 and r =−0.483, respectively, and the eccentric strength ratio of the external to internal rotators (r =−0.505). In addition the dynamic control ratio was lower than the recommended values for overhead athletes, which may expose/predispose the players to shoulder injury.

Authors: Tasmektepligil M. Yalcin , Ozkaya Ozgur , Kabadayi Menderes , Kuzucu O. Erinc
Published: October 2018

The elliptical Wingate test (EWT) is a new exercise modality that enables whole body activation during tests, while the cycle Wingate test (CWT) is a traditionally used method for anaerobic performance. The purpose of this study was to analyze total peak blood lactate, plasma volume change in lactate and heart rate responses as well as peak power, average power, minimum power, power drop and fatigue index ratio on this new exercise modality and to compare the obtained results with those derived from the CWT. Based on a sample of 20 healthy subjects all of the above parameters were significantly greater for the EWT than for CWT (p0.000). Consequently the EWT is associated with greater physiological responses and anaerobic outcomes compared to the CWT.

Published: October 2018

To assess the subsequent testosterone/cortisol ratio (TCr) from flywheel-based resistive exercise, using a within-subjects design volunteers (7 men, 10 women) performed three seated leg press workouts on an ergometer (YoYo Technologies, Stockholm Sweden). Comprised of ten-repetition sets, the workouts entailed: a three-set protocol composed of concentric and eccentric actions(CE3), as well as concentric-only paradigms of three (CO3) and six (CO6) sets. Venous blood, collected before bouts and at one and 30 minutes post-exercise, was used to quantify the TCr. Data were examined with ANOVA and multivariate regression. ANOVA yielded a gender x time TCr interaction, as male values declined significantly yet women's data were unchanged. With the TCr at one and 30 minutes post-exercise as separate criterion measures, and data pooled across genders and workouts, multivariate regression revealed significance per dependent variable. Univariate correlations showed the best predictors of the post-exercise TCr in descending order were: body mass, average power and delta lactate. Gender and quadriceps muscle volume may have acted as confounding variables to allow body mass to the best current study predictor. Continued research should examine additional predictor variables, as current results only accounted for roughly 30% of the total criterion measure variance.

Authors: Steinfeld Yael , Shabat Shay , Nyska Meir , Peretz Chava , Dvir Zeevi
Published: October 2018

Background: Outcome measures of operative intervention for ankle fractures indicate poor subjective and objective results. Though patients regain full range of motion they often complain of pain and fatigability. Specifically, there is a paucity of data regarding strength characteristics of the relevant muscles after surgical intervention.

Objective: Describe the strength characteristics of ankle invertors(INs) and evertors (EVs) and explore their relationship to the ankle-hindfoot scale (AHS) in patients after surgical intervention for ankle fractures.

Method: Bilateral isokinetic concentric and eccentric INs and EVs strength was measured in 24 patients, 6–12 months following surgery. Additional subjective and objective factors were evaluated using the AHS.

Results: Strength of the involved limb muscles was significantly lower compared to the contra-lateral muscles (p<0.0001). However, strength reduction was significantly greater in the INs (27.6–37.5%) than the EVs(14.4–24.3%), (p=0.0005). The EVs/INs ratio of the uninvolved limb(89–102%) was significantly lower than the ratio of the involved limb(111–141%), (p<0.0001). The clinical status of the limb was found to have a significant effect on all dynamic control ratios (DCRs): EVR(E)/INV(C), INV(E)/EVR(C), EVR(C)/INV(E), and INV(C)/EVR(E) (P<0.0001, P=0.0032, P=0.0001, and P=0.0015, respectively). A significant relationship was found between the mean AHS score and relative unilateral weakness (r=−0.58, p=0.003).

Conclusions: Strength reduction could be one of the reasons for the functional decline following ankle fractures. The weakness of the INs muscles of the ankle is more pronounced than that of the EVs.

Published: October 2018

The aim of the current study was to determine ball velocity and throwing distance in standing and running throw-in techniques, and to correlate this performances with isokinetic torques of the, elbow, shoulder, and trunk extensors and flexors. 14 male amateur soccer players volunteered to participate to the current study. Concentric Isokinetic tests were measured at 60 and 180°/s angular velocities for elbow and shoulder, 30 and 120°/s angular velocities for trunk. Ball velocity was measured by a radar gun and the throwing distance was measured regarding throw-in performance. Unpaired t-test was used to analyze ball velocity and throwing distance differences between two different throwing techniques. To clarify relationship between isokinetic strength values and ball velocities and distance which occur during two types of throwing techniques Pearson Correlation Analyze was used.

There were no statistical significant differences regarding throwing velocity and distance between two different throw-in techniques. Even though, the isokinetic values and throwing velocities did not correlate with each other, there was a positive correlation between standing throw-in distance with elbow (non–dominant flexion at 60 and 180°s $^{-1}$ ), shoulder (dominant flexion-extension at 60 and 180°s $^{-1}$ , non-dominant extension at 60 and 180°s $^{ - 1}$ ) and trunk (flexion at 30 and 120°s $^{ - 1}$ ). The only correlation between running throw-in and throwing distance occurred in shoulder(dominant extension at 60°s $^{ - 1}$ ) and trunk (flexion at 30°s $^{ - 1}$ ). In conclusion, the isokinetic strength values regarding upper extremity is strong factor that describes standing throw-in performance. However; it is not highly correlated with the running throw-in performance in soccer.

Published: October 2018

This study analyzed relationships between bilateral concentric(60°/s, 180°/s, 240°/s) and eccentric (30°/s) knee extensor and flexor strength differences, and linear (40-meter sprint), and change-of-direction (T-test) speed in 16 male team sport athletes. It was hypothesized that lower between-leg strength differences would be associated with faster speeds. Subjects were divided into faster and slower groups based on total time; a one-way analysis of variance (p ⩽ 0.05) determined bilateral torque and work differences that distinguished the groups. All data was combined to correlate (p⩽ 0.05) torque and work differences with sprint times. The faster group exhibited greater differences in concentric knee extensor torque at 240°/s (faster=11.74 ± 8.65%; slower= 4.13 ± 4.34%), and smaller differences in eccentric knee flexor torque(faster=5.64 ± 4.10%; slower=12.41 ± 7.55%) and work(faster=6.36 ± 6.65%; slower=15.55 ± 6.05%). Negative correlations were found between concentric 180°/s and 240°/s knee extensor torque differences and sprint times; however, speed was not negatively affected. Positive correlations existed between eccentric knee flexor work differences and sprint times. Eccentric strength differences negatively impacted multi-directional speed, as balanced eccentric strength is necessary for effective sprinting, deceleration, and changing direction.

Aim: To determine how do performance parameters of the trunk and knee flexors and extensors vary with age.

Subjects and method: 215 subjects (82 men and 133 women), were divided into three age groups: 20 (mean 22.69, SD=1.72, min=20.0; max=28.0), 40(mean 44.81, SD=2.58, min=40.0; max=49.0) and 70-yearold (mean 70.23, SD=2.54, min=65.0; max=74.0).

Results: The values of the peak torque was incrementally reduced with age, more so in men and with respect to the extensors of the trunk.

Conclusion: The results point out to a selective reduction in trunk muscles function. Given the functional significance of these muscles, prevention programs targeting the elderly should take special attention of this finding.

Published: October 2018

The concept of small scale biorefinery from lignocellulosic biomass demonstrated the efficiency of energy and environment through research works at a pilot plant of University of Technology, VNU-HCM. The concept focused on studying bioethanol production in which pretreatment is one of key steps to achieve the efficiency. The pretreatment using NaOH solution 1.0 wt % removed lignin effectively but it is not considered as an eco-friendly chemical. Therefore, this study aims to investigate the alkaline pretreatment using Sodium Bicarbonate (NaHCO3), which is argued to be more environment-friendly and quite cheap. A variety of different conditions were investigated to optimize the pretreatment, including concentration of Sodium Bicarbonate (2.0-8.0 wt%), rice straw content (2.5-10.0 wt%), reaction temperatures (from room temperature to 80oC) and soaking time (4h-32h). The optimized condition was also investigated in combination with ultrasound and stirrer. The results showed that sodium bicarbonate is of quite potential to be used in the rice straw pretreatment. In addition, the waste of water from pretreatment was utilized to absorb CO2 in Biogas which was obtained from Thai My Demonstration plant in Cu Chi District.
ATOMIC FUNCTIONS AND THEIR GENERALIZATIONS IN DATA PRO-CESSING: FUNCTION THEORY APPROACH
Authors: Brysina Iryna Victorivna , Makarichev Victor Olexandrovych
Published: October 2018

Theory of atomic functions, which are solutions with a compact support of the linear functional differential equations with a constant coefficients and linear transforms of the argument, was created in the 70's of the 20th century because of the necessity to solve different applied problems, in particular, boundary value problems. One of the reasons for the appearance of atomic functions and some other classes of functions was the inability to use such classic approximation tools as algebraic and trigonometric polynomials. V.A. Rvachev up-function is the most famous and widely used atomic function. With the passage of time and the development of technologies, the existing problems are changing and fundamentally new problems appear. For instance, now the big data processing is one of the most important problems. It should be mentioned that the suitable mathematical tools must be used to obtain the desired result. This paper is devoted to fundamentals of applications of some atomic functions and their generalizations to data processing and lossy information compression. In this paper we consider the main properties of these functions from the function theory point of view and give their interpretation with respect to information processing. Smoothness, compact support and good approximation properties are the main advantages of atomic functions. Moreover, the spaces of atomic functions and the spaces of generalized Fup-functions, which are the natural generalization of V.A. Rvachev Fup-functions, are asymptotically extremal for approximation of periodic differentiable functions. This means that in the terms of A.N. Kolmogorov width these functions are just as effective as classic trigonometric polynomials {1, cos(nx), sin(nx)}. Hence, the replacement of discrete transforms based on trigonometric functions on similar transforms based on atomic functions and generalized Fup-functions is quite promising. For this purpose we introduce discrete atomic transform and generalized discrete atomic transform. We also discuss the dependence of data processing results on order of smoothness and size of support of the used functions. Theoretical justification of the application of some atomic functions and generalized Fup-functions to data processing and, in particular,  lossy data compression is the main result of this paper

The questions connected with increase of efficiency of functioning of a wind power plant with a vertical axis of rotation are considered.Such plants convert the energy of the wind flow into rotational energy of the generator shaft, pump or other actuators. An overview of the design options for wind turbines of this type is presented. For vertically-axial wind power plants, in comparison with horizontally-propeller ones, it is possible to increase their efficiency by providing insensitivity to wind direction change. This is possible provided that the angular position of the blades with respect to the wind flow is continuously and purposefully changed as the wind turbine rotates. The principle of increasing the efficiency of the wind power plant is proposed due to the synchronous control of the position of the blades, depending on the direction and speed of the wind flow. The implementation of this principle is considered in detail for a four-bladed wind turbine. Depending on the direction and magnitude of the wind flow, as well as the angular velocity of rotation of the turbine, the value of the angle of the initial installation of the blades was analytically obtained, which ensures the maximum efficiency of using the wind plant. The functional scheme of the control system of the orientation of the four blades is formed. This system uses information about the current power of the generator, the rotation speed of the wind turbine, the direction and speed of the wind flow, obtained from the respective sensors. A detailed functional diagram of one channel of the control system has been constructed taking into account the initial exposure of the blade, which additionally uses information about the current angular position of the blade and the speed of its turn. Each such channel contains a proportional-differential controller or fuzzy logic controller. The proposed fuzzy controller has two inputs of linguistic variables - the angle of rotation of the blade and the speed of its rotation. As a kind of membership functions, a triangular distribution is chosen. A system of rules for adjusting the fuzzy controller has been developed. The computer simulation of the channel functioning of the control system with two types of regulators for the mode of initial setting of the blades with a change in wind direction was performed. Comparison of the quality of the control system with a proportional-differential and fuzzy controller is performed

Published: October 2018

Introduction: To evaluate the preoperative CEA and CA19-9 levels and their association with clinicopathologic features and mortality. Methods: This retrospective study was conducted on patients who underwent gastric surgery due to gastric adenocarcinoma from 2008 to 2015. Preoperative serum CEA and CA19-9 levels were compared according to the TNM classification and survival data were compared. Results: A total of 335 patients were included in the study with the mean age of 66.1±11.0 years. CEA and CA19-0 positivity were 29.1% and 28.1%, respectively. According to the CEA groups, T stages of the cases were statistically significant (p = 0.013). The rates of T stage 1 in group 1 (CEA positive) were significantly higher than the group 2 (CEA negative) (p=0.007). According to the CA19-9 positivity; rate of stage 2 was significantly higher in the group 1 (CA19-9 positive) (p=0.001); however, rates of stage 2 and 3 were significantly higher in the group 2 (CA19-9 negative) (p=0.004 and p=0.007, respectively). Mortality information could be accessed for 309 cases and 108 deaths (36%) were observed. The mean survival time was 45.21±2.42 months. No significant difference was observed between the groups (p>0.05). Conclusion: Patients with higher levels of CEA and CA19-9 seem to have higher grades of gastric cancer.
