Purpose: The genetic influence on the attainment of elite athlete status is well established, with a number of polymorphisms found to be more common in elite athletes than in the general population. As such, there is considerable interest in understanding whether this information can be utilized to identify future elite athletes. Accordingly, the aim of this study was to compare the total genotype scores of 5 elite athletes to those of nonathletic controls, to subsequently determine whether genetic information could discriminate between these groups, and, finally, to suggest how these findings may inform debates relating to the potential for genotyping to be used as a talent-identification tool. Methods: The authors compared the total genotype scores for both endurance (68 genetic variants) and speed-power (48 genetic variants) elite athlete status of 5 elite track-and-field athletes, including an Olympic champion, to those of 503 White European nonathletic controls. Results: Using the speed-power total genotype score, the elite speed-power athletes scored higher than the elite endurance athletes; however, using this speed-power score, 68 nonathletic controls registered higher scores than the elite power athletes. Surprisingly, using the endurance total genotype score, the elite speed-power athletes again scored higher than the elite endurance athletes. Conclusions: These results suggest that genetic information is not capable of accurately discriminating between elite athletes and nonathletic controls, illustrating that the use of such information as a talent-identification tool is currently unwarranted and ineffective.

The Test of Gross Motor Development (TGMD) measures fundamental motor skills competency and is frequently used for eligibility determination of adapted physical education services in children with disabilities. The purpose of this study was to determine if the TGMD-3 is clinically sensitive to detect deficits in the fundamental motor skills of children with disabilities (i.e., intellectual disability, autism spectrum disorder, attention deficit hyperactivity disorder, language and articulation disorders). Eighty-five children with disabilities and 85 matched controls (i.e., typically developing, individually matched on age, sex, ethnicity, and race) completed the TGMD-3. Mann–Whitney U tests identified significant differences in the total TGMD-3 scores for children with intellectual disability (p < .001), autism spectrum disorder (p < .001), and attention deficit hyperactivity disorder (p = .032). No differences were identified for children with language and articulation disorders. Comparisons of subscales (i.e., locomotor and ball skills) differed across disability groups. This study provides evidence that the TGMD-3 is clinically sensitive to identify deficits in fundamental motor skills competency.

The authors performed a clustered randomized controlled trial to investigate the effects of an aerobic and a cognitively demanding exercise intervention on executive functions in primary-school-age children compared with the regular physical education program (N = 856). They hypothesized that both exercise interventions would facilitate executive functioning, with stronger effects for the cognitively demanding exercise group. The interventions were provided four times per week for 14 weeks. Linear mixed models were conducted on posttest neurocognitive function measures with baseline level as covariate. No differences were found between the exercise interventions and the control group for any of the measures. Independently of group, dose of moderate to vigorous physical activity was positively related to verbal working memory and attention abilities. This study showed that physical exercise interventions did not enhance executive functioning in children. Exposure to moderate to vigorous physical activity is a crucial aspect of the relationship between physical activity and executive functioning.

« Quand je suis arrivée en France, […] tout ça, au fait, que j’avais vu, j’ai vécu en Pologne, j’ai transmis en France » (Folliot, 22 avril 2017). Cette notion de transmission semble importante pour Jadwiga Folliot, elle-même, lorsqu’elle décrit son parcours handballistique. Elle apparaît même comme un devoir au regard de sa trajectoire de vie. Née en 1953 à Cracovie, en Pologne, Jadwiga Nowak fait partie des meilleures juniors polonaises avant d’intégrer à 33 reprises, l’équipe nationale. Lorsqu’elle arrive en France le 1er décembre 1974, en pleine Guerre froide, des différences majeures transparaissent dans l’organisation du handball, et plus généralement dans la gouvernance du sport, entre la France et la Pologne. A partir de témoignages, de coupures de presse mais également d’archives institutionnelles de la Fédération Française de Handball, nous avons identifié les différents rôles assumés par Jadwiga Folliot dans le développement du handball au sein de l’Association Sportive de Mantes la Jolie, puis du département des Yvelines et plus largement au niveau de l’équipe de France qu’elle va intégrer en décembre 1975.Si elle ne peut importer le système sportif professionnel polonais en France, pays dans lequel le handball est encore amateur, il semble qu’elle ait réussi à importer certains aspects qui ont ensuite permis de hausser le niveau technique non seulement de son équipe de club, l’AS Mantaise, mais aussi et surtout de l’équipe de France féminine de handball.

Background: A variety of intensity, load, and performance measures (eg, “power profile”) have been used to characterize the demands of professional cycling races with differing stage types. An increased understanding of the characteristics of these races could provide valuable insight for practitioners toward the design of training strategies to optimally prepare for these demands. However, current reviews within this area are outdated and do not include a recent influx of new articles describing the demands of professional cycling races. Purpose: To provide an updated overview of the intensity and load demands and power profile of professional cycling races. Typically adopted measures are introduced and their results summarized. Conclusion: There is a clear trend in the research that stage type significantly influences the intensity, load, and power profile of races with more elevation gain typically resulting in a higher intensity and load and longer-duration power outputs (ie, >10 min). Flat and semimountainous stages are characterized by higher maximal mean power outputs over shorter durations (ie, <2 min). Furthermore, single-day races tend to have a higher (daily) intensity and load compared with stages within multiday races. Nevertheless, while the presented mean (grouped) data provide some indications on the demands of these races and differences between varying competition elements, a limited amount of research is available describing the “race-winning efforts” in these races, and this is proposed as an important area for future research. Finally, practitioners should consider the limitations of each metric individually, and a multivariable approach to analyzing races is advocated.

Purpose: To investigate whether providing athletes with a choice regarding the number of repetitions to complete in a potentiation protocol would enhance jumping performance compared with protocols in which the number of repetitions is predetermined. Methods: Fifteen male basketball players completed 4 testing sessions separated by 72 hours. In the first session, individual optimum power loads in the barbell jump squat were determined. In the following 3 sessions, the athletes completed 3 sets of 3 potentiation protocols using optimum power load jump squats in a partly randomized order: (1) The traditional condition included 6 repetitions per set, (2) the self-selected condition included a choice regarding the number of repetitions to complete per set, and (3) the imposed condition included the same number of repetitions per set as the self-selected condition, but the number was imposed on the athletes beforehand. The jumping performance was determined as jump squat test height and measured using a force platform before and 30 seconds, 4 minutes, and 8 minutes after completing the protocols. Results: The self-selected condition led to superior jumping performance compared with the 2 other conditions across all post measures (P < .05; range: 0.3–1.3 cm). Compared with the traditional condition, the imposed condition led to superior jumping performance across all post measures (range: 0.2–0.45 cm), although not statistically significant at post 4 minutes and post 8 minutes. Conclusions: Choice provision concerning how many repetitions to complete in a potentiation protocol is a useful performance-enhancing strategy. Improved potentiation–fatigue ratio and motivational factors are sought to explain these effects.

The authors investigated the effects of unstable strength training (UST) without or with cognitive training (C+UST) on functional performance in community-dwelling older adults. A total of 50 participants were randomly assigned (1:1) to either 24 weeks of thrice-weekly UST (n = 25) or C+UST (n = 25). All participants performed moderate-intensity strength exercises using unstable surfaces, and C+UST participants simultaneously received cognitive training in addition to UST. Primary outcomes included measures of functional performance: single- and dual-task timed up and go tests. Secondary outcomes included dynamic balance, mobility, handgrip strength, flexibility, quality of life, and concern about falling. The authors observed similar improvements on functional performance through the interventions. The C+UST group experienced additional gains at completion (single-task timed up and go: −0.90 s, 95% confidence interval [–2.38, –0.03]; dual-task timed up and go: –4.80 s, 95% confidence interval [–8.65, –0.95]) compared with the UST group. Moreover, significant differences were observed in mobility (sitting-rising test: −1.34, 95% confidence interval [−2.00, −0.20]) at 24 weeks. Both exercise modes improved single-task functional performance, while adding cognitive-training-optimized dual-task functional performance gains.

Purpose: The aim of this study was to evaluate whether anthropometric and fitness characteristics have changed between former and current elite male and female Austrian young ski racers (U11–U15). Methods: A battery of anthropometric, general, and skiing-specific fitness tests was conducted annually. In total, 1517 participants (846 males, 671 females) who were tested in 2005–2009 (“former athletes” n = 805) and 2015–2019 (“current athletes” n = 712) were included. Independent t tests and Cohen d were calculated to compare the two 5-y periods, separated by sex and age group. The level of significance was set at P < .05. Results: No significant change in anthropometric characteristics was found over the decade. Current young ski racers performed significantly better in the maximal core flexion strength test in all age categories (ES = 0.88–1.50; P < .02). Core extension strength values were higher in current male U12 and female U12 and U13 athletes (ES = 0.54–0.71; P < .01) and better postural stability values in the lateral direction were found in the age categories U12 and U14 (ES = 0.36–0.68; P < .05), as well as in the forward/backward direction in the age categories U12–U14 (ES = 0.38–1.12; P < .03). Lower-leg extension strength values were apparent in the current U13–U15 age categories (ES = 0.36–1.03; P ≤ .001) and lower drop-jump reactive strength indices in the U13–U15 male athletes (ES = 0.49–0.80; P < .01). Conclusions: Current and former young ski racers differ significantly in some fitness parameters, which might lead to the assumption that some aspects (such as core strength) have gained more focus in athletic training during the last years compared with 15 y ago.
