Physical activity is a complex behaviour influenced by individual, social, environmental, and policy factors. Understanding these factors of specific populations is a prerequisite for effective public health interventions. The main aim of this study was to determine the relationship between participation in sports, exercise, and other physical activities and the perception of environmental and policy correlates of physical activity in Croatia. The sample consisted of 1031 randomly selected Croatian citizens and data were collected within the “Special Eurobarometer 472” using questions about: a) participation in sport, exercise, and other physical activities and b) the environmental and policy factors of physical activity including opportunities for engaging in physical activities, the offer of sports clubs, and level of the support from local authorities. The results of the logistic regression analysis showed that people who perceived their local sports clubs and other service providers as offering more opportunities and those who felt that their local government supported physical activity were more likely to be actively involved in sports and exercise (p<.05 for all). Furthermore, the perception of greater opportunities for physical activity in the local environment is associated with increased involvement in recreational physical activities that are not related to sports (p<.05). Future strategies aiming at encouraging citizens to engage in sports and exercise should be based on strengthening cooperation between local authorities and local sports clubs, while the promotion of other physical activities should incorporate providing adequate infrastructure for engaging in physical activities and informing citizens about the provided opportunities.

High-intensity functional training (HIFT) can play a major role in preventing cardiometabolic disease. The majority of HIFT interventions incorporate CrossFit (CF) training. We measured aerobic capacity, metabolic response during high-intensity interval exercise (HIIE), resting mitochondrial oxidative capacity, and resting vascular function in adults who participated in CF training (> one year) vs. a sedentary group completing <2 h·wk-1 of structure exercise for > one year (SED). Twenty-one participants were recruited (CF n = 13 vs. SED n = 8). CF participants had a 33.0% greater relative VO2 peak (p<.001) and lower body fat percentage (CF = 18.6 [3.8] vs. SED = 30.3 [8.4]; p<.001). CF participants had higher exercising substrate oxidation when expressed as absolute and body weight relative values (p<.013), but not when expressed relative to lean mass (p>.200). CF participants had greater mitochondrial oxidative capacity (p=.014). There were no differences in large artery function, but CF participants had greater baseline arterial diameter (p=.004) and faster reperfusion following arterial occlusion (p<.05). These data support HIFT programs’ effectiveness in improving fitness, weight status, and metabolic, mitochondrial, and vascular function.
高强度功能训练(HIFT)可以在预防心脏代谢疾病中发挥重要作用。大多数HIFT干预包括混合健身(CF)训练。我们测量了参加CF训练的成人的有氧能力、高强度间歇运动(HIIE)期间的代谢反应、静息线粒体氧化能力和静息血管功能(>1年)与久坐组相比，久坐组在1周内完成2小时的结构锻炼。一年(SED)。21名参与者被招募(CF n = 13 vs SED n = 8)。CF参与者的相对VO2峰值高出33.0% (p<.001)，体脂率较低(CF = 18.6 [3.8] vs SED = 30.3 [8.4];p&肝移植;措施)。当以绝对和体重相对值表示时，CF参与者有更高的运动底物氧化(p<.013)，但当以瘦体重相对值表示时则没有(p>.200)。CF参与者线粒体氧化能力更强(p= 0.014)。大动脉功能没有差异，但CF参与者的基线动脉直径更大(p= 0.004)，动脉闭塞后再灌注更快(p< 0.05)。这些数据支持HIFT项目在改善健康、体重状况、代谢、线粒体和血管功能方面的有效性。

The purpose of this study was to investigate the role of set structures in designing bodyweight power training (BWPT). Specifically, we compared the effects of Cluster set structure undulating variant (CSSUV) and Traditional set structure (TSS) on training load and performance during vertical jumping sessions. Sixteen active males participated in this study. We designed four training sessions that consisted of 144 countermovement jumps distributed into 12 sets, where number of repetitions varied for CSSUV sessions’, and for TSS sessions’ was fixed. In addition, both of the applied set structures included sessions with short (i.e., 60 seconds) and long rest periods (i.e., 120 seconds), while training volume was separately analysed for the first six sets (i.e., small volume) and last six sets (i.e., large volume). We calculated external load, internal load and performance variables. The obtained results suggest that CSSUV allows superior utilization of applied external load, reduction of internal load and overall higher performances that are maintained during entire training session compared to TSS. The present study provides important findings about advantages of CSSUV over TSS in terms of external load, internal load and performances during vertical jumping sessions, and therefore, it might be more suitable approach for designing BWPT.

Posturography normative data in healthy populations is crucial for several reasons including monitoring the independence issues related to activities of daily living (ADLs), fall and incapacity avoidance, and residual injury impairment. The Biodex Balance System requires updated normative data regarding healthy persons because of recent revisions to the Biodex Balance System. Further, this study aimed to determine and compare gender and limb performance in 161 adults aged 18-55 years (n = 80 males; n = 81 females). Assessments involved both static and dynamic stability tests such as double-leg and single-leg balance tests at platform stability which served as outcome measurements. Females performed significantly (p≤.05) better on double-leg static balance (p=.031), double-leg dynamic balance (p=.002), and single-leg dynamic balance on both the left (p=.003) and right legs (p=.013) when compared to males. The normative values and findings of this study not only enable the evaluation of individual performance regarding the balance of adults but also suggest the need to use gender-stratified normative data when using the Biodex Balance System to interpret double- and single-leg, static and dynamic balance test performance.

The purpose was to ascertain the effects of a 12-week intervention program based on exercises of mobility and dynamic strength on the stabilization of neck and trunk muscles in people with neck or low back pain according to gender. Forty-two subjects (n = 25 males and n = 17 females; age 49.62±8.82 years) with neck or low back pain completed a recovery-training program focused on improving mobility and strength in the stabilizing muscles of the trunk and neck. A range of motion test, a strength (maximum voluntary contraction) test and the muscle strength asymmetry of the muscle groups analyzed were assessed at the beginning (T1), after six (T2) and after 12 (T3) weeks of intervention. Improvements were seen in nine out of the 12 range of motion variables at T2 (ES=0.52 to 1.26, moderate-high; p<.05) and T3 (ES=-0.28 to -0.44, low; p<.05 or p<.01). Improvements were also evident in all the strength variables at T2 (ES=-0.81, high; p<.01) and T3 (ES=-1.08 to -0.95, high; p<.01). In contrast, in the strength asymmetry variables improvements were found in one out of the five variables analyzed at T2 (ES=-0.81, high; p<.01) and two out of five at T3 (ES=- 1.08 to -0.95, high; p<.01). In conclusion, the intervention was effective for improving range of motion and strength. However, to improve muscle strength asymmetry it may be necessary to include specific exercises.

Grand Slam tennis tournaments are played on different surfaces. The aims of the present study were to analyse the technical differences in the Grand Slam tournaments (Australian Open or AO, Roland Garros or RG, Wimbledon or W, and the United States Open or US), as well as to establish differences between winning and losing players. A total of 580 sets in 248 matches played in Grand Slams between 2017 and 2018 were analysed. To observe differences between the tournaments, a one-way analysis of variance (Kruskal Wallis) with the Bonferroni post-hoc test was performed. Univariate (Wilcoxon test) analysis of data was carried out to show the differences between the winning and losing performances of sets. Players who had more aces, points won on the 1st serve, winning shots and net points won more matches in the AO, W and US than in the RG (p<.05). However, in RG, players won more receiving points (43.56% of the points played) with chances to break the opponents’ service game. The results also showed that the winning players were superior in both service and receiving, and the most influential variables on the outcome of the match were percentage of receiving points won, break points won, and percentage of points won on the first serve. Such knowledge may have implications in the design of appropriate game strategies and specific training sessions to improve performance in professional women’s tennis.

The architectural features of the hamstring muscle group are important to prevent injury or to reduce the risk of re-injury. Besides, eccentric training is often used in the rehabilitation of hamstring injuries. The aim of this systematic review was to examine the changes created by eccentric training on hamstring muscle architecture and to determine the minimal values of training duration and intensity for requiring functional changes. The research was conducted on the PubMed, Scopus, Web of Science, COCHRANE, CINAHL, and Pedro databases. Full-text studies examining the effect of eccentric training on at least one parameter of the hamstring muscle architecture were included in the review. Studies on cadavers and animals and studies involving different types of training combined with eccentric training were excluded. Twelve of the 7954 studies met the set criteria. According to the results, eccentric training undoubtedly increases fiber length. However, the pennation angle tends to decrease. On the other hand, muscle thickness and cross-sectional area tends to increase depending on the eccentric training. Although the frequency, number of sets and number of repetitions in sets were similar in the examined studies, muscle architecture changes were different. We think that eccentric training duration and the number of repetitions in total or per training session seem to have an impact on muscle architecture. In order to determine the minimal eccentric training program that can create these changes, quality research is needed to examine the duration, intensity and methods of eccentric training.
腘绳肌群的结构特征对于防止受伤或减少再次受伤的风险很重要。此外，在腘绳肌损伤的康复中，常采用偏心训练。本系统综述的目的是检查偏心训练对腘绳肌结构造成的改变，并确定需要功能改变的训练时间和强度的最小值。该研究在PubMed, Scopus, Web of Science, COCHRANE, CINAHL和Pedro数据库上进行。研究偏心训练对至少一个腘绳肌结构参数影响的全文研究被纳入综述。排除了对尸体和动物的研究以及涉及不同类型的训练结合偏心训练的研究。7954项研究中有12项符合既定标准。根据结果，偏心训练无疑会增加纤维长度。但笔触角度有减小的趋势。另一方面，肌肉厚度和横截面积倾向于随着偏心训练的增加而增加。虽然在检查的研究中，频率、组数和重复次数是相似的，但肌肉结构的变化是不同的。我们认为，古怪的训练时间和总训练次数或每次训练似乎对肌肉结构有影响。为了确定能够产生这些变化的最小偏心训练计划，需要进行高质量的研究，以检查偏心训练的持续时间、强度和方法。

The main aim of the present study was to determine the short- and ultra-short-term heart rate variability (HRV) during different physical and physiological tests and to compare HRV to different performance levels. The latter aim was to compare participants’ short- and ultra-short-term heart rate variability before-duringpost- tests. Our hypothesis was that there would be a significant difference between test performance and HRV parameters, and the high performing group would have significantly higher HRV parameters than the low performing group. Fifty-three healthy men (Mage=26.9±4 years, Mheight=177.9±5.7 cm; Mweight=77.8±8.7 kg) were recruited in the current study. We completed the data collection procedure for each participant in four consecutive days. On day-1, anthropometric measurements were conducted and then participants performed isokinetic tests. On day-2, participants performed anaerobic tests; on day-3 equilibrium tests, and on day-4 aerobic capacity tests. The HRV records of all participants were obtained before, during and after all these tests. Based on the participants’ performance, they were divided into two groups: participants in G1 had lower performance and those in G2 higher performance. A two-way repeated measures ANOVA yielded significant differences in HRV values obtained in the four different tests. There was a significant difference between fitness test performance and the variation of short- and ultra-short-term HRV parameters. Also, significant differences in HRV values before, during, and after the testing were observed. Key words: autonomic nervous system, heart rate variability, physical and physiological tests

Also, significant differences in HRV values before, during, and after the testing were observed.\u0000Key words: autonomic nervous system, heart rate variability, physical and physiological tests","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42423618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to identify which cognitive and perceptual skills best discriminate elite female handball players according to the age group to which they belong to. The sample consisted of 73 Portuguese national teams’ female handball players, aged between 11 and 29 years, with an average of 7.5 (± 3.7) years of practice. The following tests were applied: Thurstone Identical Figures Test, Toulouse-Piéron Concentrated Attention Test, and the Nideffer Attentional and Interpersonal Style Inventory to evaluate perceptual skills, the polyreactiometer for Windows – PRWin to evaluate information processing, and an evaluation protocol for precision in anticipation using the temporal occlusion paradigm. The interpretation of the obtained discriminant function was based on the structure of the coefficients greater than |0.30|. The Seniors’ age group is discriminated from that of Talents by their better reaction, perception, and attention times, namely, by the ability to integrate several stimuli simultaneously and by a better capacity to anticipate future events more accurately. This discriminating model can help coaches recruit players as well as improve psychological training programmes.

Joint position sense and force reproduction are the most commonly used measures of proprioception. It is interesting to measure proprioception in integration of the factors most commonly viewed as the most important in table tennis—speed, in particular quick reaction. The aim of this study was to evaluate the accuracy of replication of a specific range of motion and force of hand pressing under conditions of limited time. Forty table tennis players and 30 non-athletes participated in the study. Electrogoniometric and dynamometric methods were used in the investigation. The accuracy of replication of pronation and supination movements of the forearm at the elbow joint and force of hand pressing under conditions of limited time (performing the activity as fast as possible in response to visual signals) were measured. The tests performed in the study revealed that both female and male table tennis players were characterized by a higher level of forearm position sense during performing the fastest possible pronation and supination movements in most of the tasks. Better results of table tennis players than of the control group suggest that joint position and hand pressure sense integrated with quick reaction are important performance factors in table tennis. The results also indicate opportunities for using this methodology to monitor training.
