Soccer is one of the most popular sports in the world, especially in Europe. Soccer is characterized by numerous short, explosive exercise bursts interspersed with brief recovery periods over an extended period of time (90 minutes) (Meckel et al., 2009). Soccer performance, read more which depends on the technical skills and physical fitness of the players, is known to significantly influence match performance. The simultaneous use of both technical skills and fitness in soccer training would produce extremely effective performance (Little and Williams, 2007). Agility, acceleration, change of direction, deceleration, and sprinting are regarded as critical technical skills and the main components of soccer training.

The ability to sprint and to change direction while sprinting are determinants of performance in field sports, as evidenced by time and motion analysis (Sheppard and Young, 2006). In many sports, including soccer, athletes are required to accelerate, decelerate, and change direction throughout the game (Docherty et al., 1988). Often, these movements are performed in conjunction with passing, dribbling and striking movements (Abernethy and Russell, 1987; Farrow et al., 2005; Sheppard et al., 2006). Differences between higher and lower performers in anticipation and efficient decision making in accordance with sport-specific stimuli have also been mentioned in relevant literature (Abernethy and Russell, 1987; Tenenbaum et al., 1996; Farrow et al., 2005).

In soccer agility, anticipating the direction and timing of the ball are crucial issues for success (Sheppard et al., 2006). However, few studies have evaluated sport-specific, physical performance tests of agility, including sprints, changes of direction and striking at the goal. Therefore, the purpose of this study was to develop and evaluate a novel test of agility and striking skill for soccer that involves sprint running, direction changing, and kicking stationary balls to the goal with accurate decision making. The classical T-drill agility test, developed by Semenick (1990), was implemented with four balls and the goal (Figure 1). Figure 1 A diagram and explanation of the new developed agility and skill test for soccer.

Disadvantages of MRI: It requires expensive and advanced equipment Unavailability in every medical center and dental office It takes a long time to use in directly TMJ It is contraindicated in the patients with claustrophobia.[27] Stainless steel and other metals used in orthodontic brackets were shown to produce artifacts.[79] Therefore, patients undergoing orthodontic treatment should be carefully evaluated for MRI needs. CONCLUSIONS Need for high speed, high density, small size, and multifunctional device has driven the development of 3D imaging. New imaging techniques require expensive software and a lot of time to operate them. The future of 3D imaging seems to be faster and more flexible robotic devices. Footnotes Source of Support: Nil.

The over emphasis of dental esthetics is increasing in daily life and concerns about the outward appearance also affect children. Anatomy, color and harmony of one’s teeth are especially important to the appearance of the face.[1,2] People who have well-positioned incisors are considered more attractive, intelligent and adjusted than others who have dental malocclusion and/or anomalies.[2,3,4] Severe deformities of the face region cause sympathy and compassion in people.[5] Paradoxically, more subtle deformities result in taunts and mockery, leading the individual to a situation of low self-esteem. A child’s smile reveals important aspects of their quality-of-life and how the child interacts in his/her environment.[6] A smile denotes a self-esteem, self-confidence and well-being.[7] Low et al.

[8] showed that children with concerns about their teeth show less smile security. Self-perception is a part of children psychological characteristics and it is essential to be aware of how much they like their smile and how happy they are with it.[1] Oral disorders may expose an individual, particularly children of school age, to an embarrassing situation. Among the various health professions, dentistry commonly experiences situations in which children and adolescents have been subjected to bullying.[9] In everyday clinical practice, children and their family seek for dental treatment concerned about teeth esthetic. Studies have investigated the effects of dentofacial appearance on psychosocial health. The findings suggest that developmental dental anomalies have a deep impact on quality-of-life.

[4,10,11] Olweus[12] describes bullying as an anti-social behavioral phenomenon that violates the rights of another person and reflects intentional and Entinostat repeated aggression, verbal or physical, against any unable to defend him/herself and can occur in any social context. Their victims may have serious psychological consequences, isolation, depression, anxiety and can generate lower performance and learning.[13] Bullying in schoolchildren is a global phenomenon[9] and its effects can be short as long-term.

Heart rate, and blood pressure The resting values of heart rate (HR), systolic (BPs) and diastolic (BPd) arterial blood pressures were within normal limits. The handgrip caused significant increases in HR, BPs and BPd (p<0.001) already at the 3rd min of exercise in all subjects. The values obtained at the 6th min were significantly higher than those at the 3rd minute of exercise (p<0.001). After 5 min recovery period, HR, BPs and BPd returned to the resting values (Fig.

To make comparisons more efficient, eight characteristics were selected from each of the three sets of climbers�� mental, technical and physical attributes (Table 3). The first and most significant canonical correlations in the new sets of mental characteristics (personality traits, temperament, locus of control and tactics), technical characteristics (coordination and technique) and physical characteristics (somatic, flexibility, physical fitness and efficiency) were high, the canonical R being 0.

82, 0.81 and 0.79, respectively. All correlations were statistically significant (p<0.001). The total redundancy values for the three sets interpreted as average percentages of the variance in one set of variables that all canonical variables explained based on another set were differentiated. This means that in analysing climber��s performance (the Max OS and Max RP set) eight mental characteristics explained 41% of the variance, eight technical characteristics �C 53%, and eight physical characteristics �C 62%. Table 3 The results of canonical analysis for selected mental, technical and physical characteristics with respect to the dependent variables Max OS and Max RP The canonical analysis helped answer the third question too.

The first to be analysed were the sets of somatic and physical fitness characteristics and that of coordination and technique (Table 4, columns 2 and 3). The total canonical R was high (0.82) and statistically significant (p<0.001). The canonical roots in the right set (the vectors of physical characteristics) explained almost 32% of the variance in the left set of variables (technical characteristics). Reversely, the first set explained 29% of the variance. The results obtained from comparing the characteristics of personality, temperament, locus of control and tactics with the somatic and physical fitness characteristics (Table 4, columns 4 and 5) showed that the right set (mental characteristics) explained almost 30% of the variance in the left set (physical characteristics).

In the reverse situation, the rate of the explained variance declined to 25%. The total canonical R was both high (0.83) and statistically very significant (p<0.001). The sets of mental and technical characteristics were compared last (Tables 4, columns Anacetrapib 6 and 7). The total canonical R was similar to its values determined from the previous analyses (0.82) and also statistically very significant (p<0.001). The canonical roots of both the right set and the left set explained a similar amount of the variance �C 38%.

According to Barbosa et al. (2009), the use of aquatic cycling has been reported in literature for three decades, though its findings are still contradictory. Alberton et al. (2010) suggest that HR in the water could be similar or higher as compared with dry land measurements. Barbosa et al. (2010) analyzed the relationships selleck chemical between musical cadence and the physiological adaptations to basic head-out aquatic exercises. The study included an intermittent and progressive protocol and the main conclusion was that increasing musical cadence imposed an increase in the physiological response. In this context, several physiologic indicators have been used in order to quantify the intensity of exertion in those environments, such as: the HR (Sheldahl et al., 1984; Reilly et al., 2003); double product (Veloso et al.

, 2003), and blood lactate concentration (Di Masi et al., 2007). In water, resting or exercising induces different physiological responses when compared with those achieved in dry-land conditions (Shono et al., 2000; Reilly et al., 2003) and are affected by a number of factors, such as buoyancy, thermal conductivity of the water (Choukroun and Varene, 2000), hydrostatic pressure (Goodall and Howatson, 2008), among others. Those responses depend also on the body positioning in the water (Millet et al., 2002; Ega?a et al., 2006) and on the type of exercise (Barbosa et al., 2009). Kang et al. (2005) compared the responses of HR between intermittent (130 �� 2 bpm) and continuous cycling (127 �� 2 bpm) on land and did not found significant differences between both methods.

The lactate concentration was significantly higher at the end of the intermittent exercise with a mean value above 7 mmol in the final stage of the IP. Contrarily, Sabapathy et al. (2004), have examined the physiological responses in 10 subjects who performed a continuous and intermittent land cycling protocol and observed that the intermittent protocol was associated to significantly lower values of HR. Unfortunately, no previous study examined the type of physiological response induce by continue or intermittent exercise in water environment. Therefore, the present study tested the hypothesis that the type of exercise (continuous vs. intermittent) would affect the physiological response and the perception of effort during aquatic cycling. Methods Participants Ten women (values are mean �� SD: age=32.

, 2012). When considered with other athletic kinase inhibitor Cabozantinib performance variables, changes in RMSSD throughout training and competition periods may indicate quality of physical adaptation, such as over-fatigue or increases in fitness (Cipryan et al., 2010; Oliveira et al., 2012; Tian et al., 2012). Additionally, it has been suggested that the RMSSD may be the preferred parameter for longitudinal athlete monitoring due to its easy calculation and interpretation (Plews et al., 2013) as well as its reduced sensitivity to breathing frequency compared to spectral measures (Pentilla et al., 2001; Saboul et al., 2013). This is particularly important when considering that field tools such as ithlete? are intended for athlete use with unsupervised data collection.

The prospect of a smart phone HRV application is attractive to coaches due to it being user friendly, affordable and time efficient. Therefore, it has potential for being utilized in field settings as an HRV monitoring tool among sports teams. Unfortunately, there are no available studies that have examined the accuracy of the ithlete? receiver and chest-strap hardware for determining HRV. This research is warranted as the merit of any field parameter depends on validity statistics when compared to laboratory derived measures. Therefore, the purpose of this investigation was to cross-validate the ithlete? HRV smart phone application with an ECG for determining ultra-short-term RMSSD. Technology for acquiring heart rate data in the field has advanced considerably over time.

Therefore, it is reasonable to hypothesize that the smart phone application with a heart rate strap and an ECG receiver will accurately reflect laboratory-derived HRV measures. Material and Methods Participants Twenty-five male (n = 17) and female (n = 8) college students from the University��s Exercise Science program volunteered for this study. Descriptive statistics for the participants are shown in Table 1. Acquisition of the data occurred between the hours of 8:00 am and 12:00 pm on week days in the Human Performance Laboratory. Volunteers were told to report to the lab in a fasted state and to avoid the consumption of stimulants (e.g. coffee). Only healthy individuals were included in this study. Those with a heart condition, illness or prescription medication were excluded.

All subjects provided written informed consent after being given a detailed account of the investigation, potential risks and were told that they may withdraw their participation at any time. The experimental protocol was granted ethical approval by the associated University��s Institutional Review Board. Table 1 Descriptive statistics (mean �� SD) of the studied sample Procedures For the ithlete?, each subject was fitted with a heart rate transmitter Cilengitide and an elastic strap (Non-Coded Polar T-31, Polar Electro Oy, Kemple, Finland) fastened securely around the upper thorax at the level of the xiphoid process.
