Limitations in mobility lead to sedentarism, which may decrease the quality of life in PwPD. Several studies demonstrated that the combination of exercise with the traditional pharmacological treatment (i.e., levodopa) is effective to improve mobility in PwPD 1-5. Although the effects of traditional modalities (e.g., walking overground and cycling) are well documented, other stimuli may also induce positive responses on mobility in PwPD. However, such studies demonstrated trivial results or effectiveness in terms of functional mobility, indicating that the exercise – mainly using non-traditional stimuli – should be carefully prescribed. To avoid practical mistakes and ensure a high probability of success in mobility rehabilitation in PwPD, rehabilitation professionals must apply up-to-date and high-quality knowledge about mobility. Also, they must recognize the effects of different exercise modalities to improve functional mobility and the motivators and barriers to exercise in PwPD 1. This infographic aims to present (1) the motiving factors and barriers of training in PwPD, (2) the main effects of four exercise modalities on functional mobility (considering its underlining mechanisms), and (3) demonstrate the training evidence to improve the functional mobility.\u0000The exercise modalities were selected from the four recent meta-analyses (searched on PUBMED) that tested the exercise effects on functional mobility and presented data related to exercise prescription for PwPD. The encouragement of other persons is the most motivating factor for PwPD during exercise. The lacking of encouragement, fatigue and depression are related to exercise barriers in PwPD 1. Suárez-Iglesias et al. 2 demonstrated that Pilates was effective to improve functional mobility, improving Timed Up and Go (TUG) performances. Interventions using hydrotherapy, with or without land-based therapy, also showed positive effects on TUG values 3. Dance modality, associated with auditory cues, promoted positive effects on gait velocity, TUG, and freezing of gait 4. Finally, Robinson et al. 5 observed that treadmill training, when compared to no-exercise ones, improved the gait velocity and step length in PwPD regardless of use or not body weight support. Overall these results were observed in patients with early to moderate stages of disease (Hoehn and Yahr < 3). These main effects and the mechanism related to the positive responses were presented in the infographic. \u0000Despite the noteworthy positive effects of exercise using these modalities in PwPD, recommendations for training prescriptions are still debatable. The characteristics of the modalities were poorly described in most of the studies. For example, even with the availability of acceptable and practical tools, the exercise intensity or its increment throughout the training was not properly reported.

Nevertheless, exercise can have beneficial effects on cognitive abilities, and these effects may vary with the environment. Therefore, it is important for the performance of individuals to understand the uncertainties about the conditions that can compromise cognitive function.\u0000AIM: To identify which hypoxic conditions can cause attention disturbance.\u0000METHOD: A total of fourteen volunteers (24.4 ± 3.9 years old; 82.8 ± 14.9 kg weight; 178.6 ± 7.9 cm height) participated in this single-blind, randomized, with a within-subjects design study. Participants completed an adapted version of the Stroop Color-Word Test (SCWT) before and after exposure in normoxia and hypoxia (FIO 2 = 0.209 and 0.138, respectively), in two conditions: (i) at rest for 30 minutes and (ii) under exhaustive effort. The data were analyzed using a Bayesian statistical approach.\u0000RESULTS: SCWT performance under hypoxic conditions showed no difference compared with exposure moments (before and after), as well as showed no difference compared with normoxic conditions. The SpO 2 in hypoxic conditions was significantly lower than in normoxia conditions, unlike HR, which revealed no difference. The hypoxia dose at rest and under exhaustive effort was 2.5 and 0.8 %.h, respectively.\u0000CONCLUSION: Despite a drop in SpO 2 and with hypoxia doses equivalent to 2.5 and 0.8 %.h, it was not possible to confirm differences in the indices related to attention.

Kinematic and coordinative variables were collected. Lactate concentrations, heart rate, and blood pressure were also measured.\u0000RESULTS: The para swimmer achieved the anaerobic threshold at  the fourth 200-m step, followed by an increase in heart rate and blood pressure. Speed and stroke frequency were higher and stroke length was lower along the 200-m steps. In contrast, a slight increase in stroke index and stability in intracyclic velocity variations occurred across intensity increments, and index of interlimb coordination was maintained as a superposition mode.\u0000CONCLUSION: The findings suggest that the swimming intensity seems to influence the para swimmer metabolic, kinematic, and coordinative behavior, with sharper alterations after the point when AnT is achieved.

Research has been fairly limited in regards to the attentional focus reported to be used by highly skilled performers or coaches. Fairbrother et al.

Meaning units that related to attentional focus were extracted from the questionnaires and categorized into associative and dissociative cues. The cues were then categorized for various attentional focus strategies.\u0000RESULTS: Results showed that elite coaches utilized multiple attentional focus strategies which included internal, external, and holistic focus cues. The most common attentional focus utilized with collegiate throwers was that of a holistic focus, which directs attention to the general feeling of the movement (Becker et al. 2019).

Motor accuracy is defined by the rules of the sport (e.g,. hits versus misses), while motor error is defined by a behavioral measure, such as how far a ball or other object lands from the target (e.g. radial error). The QE motor accuracy paradigm treats accuracy as an independent variable and determines the QE duration during an equal (or near-equal) number of hits and misses per condition per participant, while the motor error QE paradigm combines hits and misses into one data set and determines the correlation between the QE and motor error, which is used as a proxy for accuracy. QE studies within the motor accuracy paradigm consistently find a longer QE duration is a characteristic of skill, and/or interaction of skill by accuracy. In contrast, QE motor error studies do not analyze or report the relationship between the QE duration and accuracy (although often claimed), and rarely find a significant correlation between the QE duration and error. Evidence is provided showing the absence of significant results in QE motor error studies is due to the low number of accurate trials found in motor error studies due to the inherent complexity of all sport skills. Novices in targeting skills make fewer than 20% of their shots and experts less than 40% (with some exceptions) creating imbalanced data sets that make it difficult, if not impossible, to find significant QE results (or any other neural, perceptual or cognitive variable) related to motor accuracy in sport.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88989991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
