Although the influence of muscle activity on the pelvic position has been proven, research on the influence of (asymmetric) muscle fatigue on the pelvic position is inconsistent. The purpose of the present study was to assess the effects of asymmetric fatigue of the lateral trunk muscles on the pelvic position based on a pre/post/follow-up design. For the final data analysis, 38 subjects (20 men, 18 women; age 22.63 ± 3.91 years) were asked to perform side bends in sets of 20 repetitions on a Roman chair until complete exhaustion. For pre-, post-, and follow-up test (24 h after treatment), pelvic positions were recorded with a 3D photogrammetric scan. Statistical analysis showed no systematic changes in pelvic inclination and rotation after unilateral exhaustion for the three measuring times. However, highly individual, non-systematic changes in pelvic positions were present, especially between pre- and post-test. The follow-up measurements tend to return to the initial pre-test state. Unilateral fatigue of the lateral flexors of the trunk affects the pelvic position in a non-systematic way.

In sports and daily life, we often experience situations where we should carry an object by pushing it. In this study, we analyse sumo, a Japanese traditional sport, in which one can be a winner by pushing the opponent to the outside of dohyo, the wrestling ring. The optimal strategy for the lighter wrestler to carry the heavier opponent by sliding on dohyo is explored in terms of physics. Although the lighter wrestler can never slide the opponent by pushing forward, this can be achieved by exerting the force diagonally upward. As a result of analysis, we obtain the magnitude and direction of the force that should be applied to initiate the sliding motion and ensure its fastest movement. The result reveals the existence of a critical weight ratio of the wrestlers; if the ratio is upper than a certain value, the lighter wrestler should push to a specific direction, while otherwise the optimal force direction depends on the weight. Due to the generality of physics and mathematics, the application is not limited to sumo; the result provides the most effective way to carry an object on a floor in all activities in sports, exercises, and daily life.

Subjective well-being is a good indicator of the individual's psychological health. High levels of subjective well-being have been found in adolescents who are regularly physically active, less prone to negative emotions, more easily able to cope with life's problems and challenges, have a lower body mass index, and exhibit higher levels of life satisfaction. The participants in this research were adolescents from the Republic of Croatia, N = 756, of which 407 (53.8%) were handball players and 349 (46.2%) were adolescents from the control group not physically active. The research was conducted in elementary schools and handball clubs with adolescents in 2006 and 2007. Instruments used in this research are Life Satisfaction Scale and PANAS. Adolescent handball players are more satisfied with life, they express higher levels of positive affect and lower levels of negative affect compared to adolescents who are not involved in some form of kinesiology activities.

The use of performance enhancing substances among elite athletes is a well-known phenomenon, but data on prevalence are inconsistent. The aim of this study was to investigate (1) the prevalence of doping use in Dutch elite athletes and (2) the attitude of elite athletes with regard to the use of performance enhancing substances. A total of 272 elite athletes completed an online questionnaire about doping use using the randomised response method and about their attitude towards the use of performance enhancing substances. The estimated prevalence of the use of doping among Dutch elite athletes during the last 12 months was 12.5 percent (95% CI 3.0 to 24.7%). The prevalence for using non-prohibited medication (without medical necessity) during the last 12 months was 15.4% (95% CI 7.1 to 23.7%). One in four athletes (23%) accepts the use of medication on prescription without a medical necessity, in order to enhance their performance. Doping prevalence among Dutch elite athletes is estimated at 12.5%, with a confidence interval from 3 to 25%. Acceptance of other performance enhancing substances is relatively high demonstrating that educational and preventive programs are essential in the fight against doping and the protection of athletes.

Resistance training is one key method for improving physical conditioning. With this purpose, Menatechpro System® has designed an avant-garde garment that includes elastomeric technology that may stimulate the neuromuscular system in a better way, but a deeper knowledge of its effects is needed. Objective: To explore the effects of a new garment with elastomeric technology on upper-limb performance, and neuromuscular, perceptual, and cardiovascular responses in two upper-extremities exercises. Methodology: Fit young men trained in resistance exercises performed a seated shoulder press (80% of one-repetition maximum) and push up (bodyweight) until muscle failure with the garment that incorporates the elastomeric technology versus a placebo garment without it. The number of repetitions, mean propulsive velocity, mean and peak muscle activation, rate of perceived effort and perceived velocity, and heart rate were analysed. Possible differences were obtained with a two-way mixed ANOVA of repeated measures with post-hoc analysis. Results: Compared with a placebo garment, the use of this new garment with elastomeric technology improved positively the physical performance and muscular activation during the exercises analysed (p ≤ .05). Conclusion: Menatechpro System®'s elastomeric technology integrated into the garment could provide an optimal neuromuscular stimulus for the development of the performance during the upper extremity training.

A research study employing a non-equivalent pretest-posttest comparison group design was used to measure online and face-to-face (FTF) yoga instructional methods and their effects on anxiety, increased flexibility, and perceived behavioural intentions to practice yoga in the future. This study was conducted to discover if online yoga course instruction was just as effective as or more so than a course taught FTF. Findings suggest that online yoga instruction was significantly more effective in reducing the state anxiety of the students. However, there was no significant difference between groups on trait anxiety indicating that either method was equally effective. In contrast, the F2F course was significantly more effective in reducing the appearance anxiety of students when compared to the online yoga course. Students in FTF and online increased in flexibility with no significant difference between groups. Based on these results, online yoga can reduce certain types of anxiety and be just as effective at increasing flexibility. The findings show that online yoga can be just as effective as and sometimes more effective than FTF yoga in some aspects important for maintenance of health and wellness in individuals.

This study aimed to quantify the differences on pain sensitivity and motor performance ankle plantiflexor muscles after performing an isometric versus an isotonic exercise task. A parallel experimental trial was carried out at the European University of the Canary Islands. A total of 47 healthy volunteers were recruited and randomly assigned to a group receiving an isometric exercise (n = 23) and a group receiving an isotonic exercise (n = 24). Pain threshold to pressure was measured at four specific points of the triceps surae neurosensory territory in medial gastrocnemius, lateral gastrocnemius, Tendo Achilles osteotendinous unit and aponeurosis plantar insertion. Furthermore, the two-point discriminatory threshold of the osteotendinous junction of the Achilles tendon and maximum voluntary contraction for plantar flexion were assessed before and after the intervention. There were no statistically significant intergroup differences for any of the variables PPT-MG (U Mann Whitney = 25; [1.265-0.650], p = .527), PPT-LG (U Mann Whitney = 25; [1.325-0.945]; p = .527) y PPT-TA (U Mann Whitney = 25; [-1.465-0.405] p = .527), D2P (U Mann Whitney = 30.5, IC95% [-0.800-1.300], p = .630) and MVC-PF (U Mann Whitney = 26.5, IC95% [-8.400, 2.900], p = .386). Isometric exercise was the only one able to modify the PPT-AP before and after treatment in a statistically significant way. In contrast, isotonic exercise was the training that demonstrated clinically significant changes in 2PD and MVC-PF before and after treatment. No statistically significant changes were identified between both groups in any of the variables studied.

The main aim of the current study was to examine cross-sectionally the correlation between demographic factors and Sense of Coherence (SOC) in Japanese university athletes. The study’s participants were 1,154 Japanese university athletes (771 males and 383 females, mean age 20.02 ± 1.13 years) that have enrolled in Japanese physical education universities. The survey items comprised sex, age, athletic events, years of an athletic career, regular position (regular or non-regular), competition level, and SOC. Binomial logistic regression analysis was then conducted to evaluate the correlation among demographic factors and SOC in universities athletes. The results of the study demonstrated that regular members of Japanese physical education universities were associated with higher SOC. Based on the above, the various life experiences that athletes experience when becoming a regular member could be associated with the establishment and development of SOC. The results of this study can lead to specific interventions toward the enhancement of SOC, not only in becoming regular members but also in SOC development and formation. Moreover, the presented results provide important information for psychological support and guidance to university athletes from a salutogenic perspective.

In this study, the mediating role of goal orientations in the relationship between a coach-athlete relationship (CAR) and collective effectiveness (CE), based on the results between the coaching efficiency variables, athlete satisfaction, and team cohesion was investigated. Participants were 252 professional athletes from four different sports. Data were obtained using questionnaires on coaching performance, athlete satisfaction, and team cohesion. Structural equation modelling showed that CAR has a positive indirect effect on athlete satisfaction and a positive direct effect on team cohesion. Athletes' satisfaction also had both direct and indirect positive effects on team cohesion. Also, the coaching effectiveness had the greatest effect on group cohesion. Coaches can use strategies and stimuli that create a sense of satisfaction in athletes and lead them to appropriate, professional, and athletic behaviour. The results show that a good quality CAR increases athletes' focus on their goals and develop their individual skills, thus improving team performance.

Correlations between sport performance and visual training have been previously demonstrated. However, it remains unclear if these relationships exist between visual tracking thresholds and in-competition decision-making metrics. Therefore, the purpose of this study was to investigate the relationship between visual tracking speed (VTS) and soccer-specific performance measures. 19 NCAA Division I soccer players VTS was measured from 1-core session on a 3-demensional multiple object tracking (3D-MOT) software NeuroTracker (NT) and soccer performance metrics were obtained from WyScout. Spearman’s rank order correlation coefficient was utilized to examine potential correlations between criterion variables. There was nonsignificant correlation between VTS score and passing accuracy (r = -0.380). However, there was a strong correlation found between consistency score and passing accuracy (r = 0.650). When examining players based on their positional role, for attacking players there were nonsignificant strong correlation with consistency and passing accuracy (r = 0.730). For defenders, consistency and defensive win rate had a strong correlation (r = 0.731). Although there was no significant correlation seen between VTS and decision-making variables when examining the entire team, there was a significant strong positive relationship between consistency scores and passing accuracy. Future research should seek to include multiple teams for improved sample size.
