This study aimed to compare the acute effect of a proprioceptive exercise session and a non-specific exercise session on knee position sense, and the static and dynamic balance of athletes. Sixty male athletes (19.4 ± 1.2 years) participated in a within-subjects repeated-measures study. Knee position sense in closed kinetic chain, and static (BESS test) and dynamic balance (Y-balance test) were measured before and after two exercise sessions, consisting of 10 min of non-specific exercise in a cycle-ergometer or proprioceptive exercise with an unstable platform. Overall, both exercise sessions significantly improved knee position sense, BESS score, and YBT composite score, and no differences were detected between proprioceptive and non-specific sessions (knee position sense, −6.9 ± 65.2% vs. −11.5 ± 75.0%, p = 0.680; BESS, −19.3 ± 47.7% vs. −29.03 ± 23.5%, p = 0.121; YBT, 2.6 ± 2.7% vs. 2.2 ± 2.2%, p = 0.305). Twenty athletes did not improve knee position sense after the exercise session (non-responders). When analyzing only the exercise responders, both sessions improved knee position sense, but the improvement was greater after the proprioceptive exercise session (56.4 ± 25.6% vs. 43.8 ± 18.9%, p = 0.023). In conclusion, a single proprioceptive, as well as non-specific, exercise session increased knee position sense and balance. The proprioceptive exercise seems to be more effective in improving joint position sense when considering only athletes who respond to the intervention.

The current systematic review aimed to compare the effect of injury-focused (specific) exercises versus more general (non-specific) exercises on pain in patients with chronic neck or shoulder pain. We searched PubMed, EMBASE, and Web of Science. Two reviewers screened and selected studies, extracted outcomes, assessed risk of bias, and rated the quality of evidence. A total of nine eligible studies, represented in 13 articles, were identified, with a considerable risk of bias. One article investigated the acute effect of single bouts of exercise on pain and reported an immediate pain reduction after non-specific exercise. Regarding short-term effects, seven out of the nine studies found no differences in pain between interventions, with inconsistent results among two other studies. Concerning the long-term effects, while pain reduction seems to be favored by specific exercises (two out of four articles), the best format is still unclear. Based on the acute effects, a single bout of non-specific exercise seems to be a better option for pain-relief for patients with chronic neck or shoulder pain. For short-term effects, there are no differences in pain between specific and non-specific exercises. Regarding long-term effects, specific exercises seem to be the best option. Nevertheless, more studies are warranted.

AbstractIn this study, we investigated whether the use of smartphone games while reading a text reduces learning performance or reading speed. We also examined whether this is affected by push notifications. Ninety-three students were randomly assigned to three learning conditions. In the gaming group (G), participants played a game app for 20 s at 2-min intervals while reading. In one subgroup, the game app sent push notifications (GN+); in the other subgroup, no notifications (GN−) were sent. In the control group (C), participants did not play a game. After the reading, participants took a multiple-choice quiz. We compared quiz scores and reading times of the groups (G) and (C) and within the gaming group (GN+, GN−) and observed no differences. Since the statistical non-significance of these tests does not entail the absence of an effect, we conducted equivalence tests, which did not demonstrate equivalence either. The experiment ensured high internal validity, yet remained inconclusive. Reasons for the similarity of performance in all groups could be non-specific exercise effects (all participants owned a smartphone), low similarity between the tasks, low variance of participants’ ability and motivation (high achieving, low ADHD scores) or low game complexity. Future research should address these questions.

The paper addresses a gap in the literature concerning the difference between enhanced and not enhanced cross-cultural learning in an international classroom. The objective of the described research was to clarify if the environment of international classrooms could enhance cross-cultural competences significantly enough or if additional focus on cross-cultural learning as an explicit objective of learning activities would add substantially to the experience. The research question was defined as “how can a specific exercise focused on cross-cultural learning enhance the cross-cultural skills of university students in an international classroom?”. Surveys were conducted among international students in three leading Central-European Universities in Lithuania, Poland and Hungary to measure the increase of their cross-cultural competences. The Lithuanian and Polish classes were composed of international students and concentrated on International Management/Business topics (explicit method). The Hungarian survey was done in a general business class that just happened to be international in its composition (implicit method). Overall, our findings prove that the implicit method resulted in comparable, somewhat even stronger effectiveness than the explicit method. The study method included the analyses of students’ individual increases in each study dimension and construction of a compound measure to note the overall results. Our findings confirm the power of the international classroom as a stimulating environment for latent cross-cultural learning even without specific exercises focused on cross-cultural learning itself. However, the specific exercise did induce additional learning, especially related to cross-cultural awareness and communication with representatives of other cultures, even though the extent of that learning may be interpreted as underwhelming. The main conclusion from the study is that the diversity of the students engaged in a project provided an environment that supported cross-cultural learning, even without specific culture-focused reflections or exercises.

Abstract Background: Measurements of physical fitness indices obtained in laboratory tests using an ergometer or a treadmill are very accurate, but they involve selected groups of muscles and do not reproduce the structure of the sport-specific exercise in judo. For this reason, researchers seek for the tests that use movements similar to the characteristic offensive techniques used during competitions (i.e. throwing). The most commonly recommended is the seoi-nage throwing test, known as SJFT (special judo fitness test).The aim of the study was to develop a new test in which uke is replaced by a dummy, in order to reduce the injury rate and ensure the safety of the participants.Methods: During the 3-week period, competitors from different weight classes performed at the beginning and then after the 2-week period one 1-minute series of continual dummy throws using the o-goshi technique and the seoi-nage technique. Post-exercise physiological responses (heart rate [HR] and blood lactate levels [La]) were evaluated.Results: Significant improvements were reported in o-goshi performance level after the training period. Physiological responses to exercise did not change significantly after training sessions. On both measurement days, post-exercise La levels were similar for o-goshi and seoi-nage throws, whereas post-exercise HR was significantly greater after seoi-nage throws.Conclusions: The dummy throwing test can be a recommended alternative to uke throwing due to the elimination of the risk of injuries to practising athletes.

Badminton is a casual outdoor sport as well as a formal game played on international level. The anatomical and physiological demands in badminton are affected by multiple factors, such as the gender, player’s style, level, equipment and surface. Physical abilities of athletes and the techniques of play influence the performance of the player. Complex skill sets require higher level of co-ordination and movement control. The complex skill sets required by badminton players are aerobic endurance, speed & agility. Agility is a key complex skill set in badminton. Agility is related to physical traits like technique, strength and power. Thus, the study hypothesized that the effect of the 6 weeks agility specific exercise program would show significant improvements on agility performance in badminton players. The primary objective was to study the effect of 6 weeks intervention on agility performance in badminton players. An experimental study was conducted in which total 62 badminton players participated. They were divided in equal numbers to experimental and control groups via random allocation method. Experimental group performed the designed protocol for 6 weeks and the control group continued their daily training of the Multi-shuttle feed training program during the same time. Agility T- test was used to assess the agility performance. The time taken to perform the agility t-test by the groups before the intervention was approximately the same with a mean difference of 20 seconds. There was a reduction in the time taken to complete the agility T-test in the experimental group after the training with a mean difference of 90 seconds between the groups. The results of comparing pre and post agility T- test readings, revealed a statistically significant difference with P<0.05. This study concluded that the 6 weeks of Agility Specific exercise program did lead to an improvement on agility in badminton players.

Abstract Background We recently developed a model of stratified exercise therapy, consisting of (i) a stratification algorithm allocating patients with knee osteoarthritis (OA) into one of the three subgroups (‘high muscle strength subgroup’ representing a post-traumatic phenotype, ‘low muscle strength subgroup’ representing an age-induced phenotype, and ‘obesity subgroup’ representing a metabolic phenotype) and (ii) subgroup-specific exercise therapy. In the present study, we aimed to test the construct validity of this algorithm. Methods Data from five studies (four exercise therapy trial cohorts and one cross-sectional cohort) were used to test the construct validity of our algorithm by 63 a priori formulated hypotheses regarding three research questions: (i) are the proportions of patients in each subgroup similar across cohorts? (15 hypotheses); (ii) are the characteristics of each of the subgroups in line with their proposed underlying phenotypes? (30 hypotheses); (iii) are the effects of usual exercise therapy in the 3 subgroups in line with the proposed effect sizes? (18 hypotheses). Results Baseline data from a total of 1211 patients with knee OA were analyzed for the first and second research question, and follow-up data from 584 patients who were part of an exercise therapy arm within a trial for the third research question. In total, the vast majority (73%) of the hypotheses were confirmed. Regarding our first research question, we found similar proportions in each of the three subgroups across cohorts, especially for three cohorts. Regarding our second research question, subgroup characteristics were almost completely in line with the proposed underlying phenotypes. Regarding our third research question, usual exercise therapy resulted in similar, medium to large effect sizes for knee pain and physical function for all three subgroups. Conclusion We found mixed results regarding the construct validity of our stratification algorithm. On the one hand, it is a valid instrument to consistently allocate patients into subgroups that aligned our hypotheses. On the other hand, in contrast to our hypotheses, subgroups did not differ substantially in effects of usual exercise therapy. An ongoing trial will assess whether this algorithm accompanied by subgroup-specific exercise therapy improves clinical and economic outcomes.

A gymnast can not succeed without enough muscle strength and endurance. The aim of this study was to determine the differences between explosive power and flexibility in young boy gymnasts at different performance levels. Ninety-five young boys who participated in this study were divided into three groups: two artistic gymnast groups (N=53) and a sedentary (N=42) group. Artistic gymnasts were classified by their performance level and sports history to an elite (E, N=15) and/or a non-elite (Ne, N=38) group. The explosive power of subjects was determined via vertical and standing long jumps. The sit and reach flexibility test was used to determine lower body muscle flexibility. Our results showed that explosive power and flexibility test records were significantly different among the three groups (P≤0.001). They led to a conclusion that sport specific exercise training resulted in a concurrent improvement in explosive power and flexibility of young gymnasts.
