The emergence of tele-exercise as a response to the impact of technology on physical activity has opened up new possibilities for promoting physical health. By integrating innovative technologies and open-source platforms, tele-exercise encourages people to stay active. In our latest analysis, we delved into the scientific literature surrounding the use of tele-exercise technologies in training healthy individuals. After conducting an extensive search on the PubMed database using the keywords "tele-exercise" and "physical activity" (from 2020 to 2023), we identified 44 clinical trials that were applicable to tele-exercise, but less than 10% of them were aimed at healthy individuals, precisely 9.09% (four out of forty-four studies analyzed). Our review highlights the potential of tele-exercise to help maintain physical fitness and psychological well-being, especially when traditional fitness facilities are not an option. We also underscore the importance of interoperability, standardization, and the incorporation of biomechanics, exercise physiology, and neuroscience into the development of tele-exercise platforms. Nevertheless, despite these promising benefits, research has shown that there is still a significant gap in the knowledge concerning the definition and evaluation of training parameters for healthy individuals. As a result, we call for further research to establish evidence-based practices for tele-exercise in the healthy population. [ABSTRACT FROM AUTHOR]

There is limited research on female football players, especially related to their physical and cognitive performance under different climactic conditions. We analyzed the impact of a hot environmental temperature on physical performance and anticipation in elite female football players during a fatigue‐inducing intermittent protocol. Elite female players (n = 21) performed the countermovement jump (CMJ) and responded to filmed sequences of offensive play under two distinct environmental temperatures (i.e., mild environment temperature‐ 20°C and 30% rh versus hot environment temperature‐ 38°C and 80% rh), interspersed by 1‐week interval. Linear mixed models were used. CMJ performance declined following the intermittent protocol on both temperature conditions (p < 0.05). Moreover, there were significant main effects for protocol on CMJ speed (m/s) (p = 0.001; ηp2 = 0.12), CMJ power (p = 0.002; ηp2 = 0.11), and CMJ Heightmax (p = 0.002; ηp2 = 0.12). After performing the intermittent protocol, exposure to a hot temperature caused a greater decline in anticipation accuracy (mild temperature = 64.41% vs. hot temperature = 53.44%; p < 0.001). Our study shows impaired performance in elite female football players following an intermittent protocol under hot compared with mild environmental conditions. We report decreased performance in both CMJ and anticipation performance under hotter conditions. The results reveal that exposure to hot temperatures had a negative effect on the accuracy of their anticipatory behaviors. We consider the implication of the work for research and training interventions. [ABSTRACT FROM AUTHOR]

Background: This study aims to show the clinical outcomes of implants supporting mandibular overdentures in edentulous patients. Methods: Mandibular edentulous patients were diagnosed with an oral examination, panoramic radiograph, and diagnostic casts for intermaxillary relations and treated with overdentures over two implants. After two-stage surgery, implants were early loaded with an overdenture at 6 weeks. Results: Fifty-four patients (28 females and 24 males) were treated with 108 implants. Thirty-two patients (59.2%) had a previous history of periodontitis. Twenty-three patients (46%) were smokers. Forty patients (74.1%) suffered from systemic diseases (i.e., diabetes, cardiovascular diseases). The clinical follow-up of the study was 147.8 ± 10.4 months. The clinical outcomes showed a global success of 94.5% of implants. Fifty-four overdentures were placed in the patients over the implants. The mean marginal bone loss was 1.12 ± 0.34 mm. Nineteen patients (35.2%) showed some kind of mechanical prosthodontic complication. Sixteen implants (14.8%) were associated with peri-implantitis. Conclusions: Based on the clinical results obtained, we can determine that the treatment of elderly edentulous patients with mandibular overdentures through the early loading of two placed implants is a successful implant protocol.

The purpose of this study was to investigate the acute effects of multi-joint resistance exercises (MJRE) with blood flow restriction on hormonal responses. Ten men participated in the study and underwent two experimental protocols in random order: four sets (30, 15, 15, and 15 reps, respectively) of MJRE (half squat and horizontal chest press) were performed with 20% of 1RM and a rest time between sets of 30 s, combined with intermittent blood flow restriction (LI + BFR protocol); and four sets (8, 8, 8, 20 reps, respectively) of the same MJRE performed with 75% of 1RM load (HI protocol), with a 90 s rest between the first three sets and 30 s between the third to the fourth set. Blood samples were collected before (PRE), immediately after (POST), and 15 min after the performance of MJRE (POST15). A time effect was observed for growth hormone (GH) and insulin-like-growth-factor-1-binding-protein-3 (IGFPB-3), but no protocol effects or interactions between protocol and times were observed (p > 0.05). There was no effect of either protocol or time (p > 0.05) on total testosterone, free testosterone, or cortisol concentrations. However, significant (p < 0.05) increases were observed in the GH serum concentrations of 2072.73% and 2278.5%, HI, and LI + BFR protocols, respectively, from the PRE to POST15 test. In addition, there was an increase of 15.30% and 13.29% in the IGFPB-3 concentrations (p < 0.05) from PRE to POST0 times for HI and LI + BFR protocols, respectively. Furthermore, there was a decrease of −6.17% and −11.54%, p = 0.00, between the times POST0 to POST15 in the IGFPB-3 for the HI and LI + BFR protocols, respectively. It is concluded that multi-joint resistance exercises combined with intermittent blood flow restriction seemed to promote acute hormonal responses in a manner similar to traditional exercise with high loads. Future studies may investigate whether chronic use of LI + BFR with MJRE may promote muscle hypertrophy. [ABSTRACT FROM AUTHOR]

Air Bike ergometers have recently appeared and become popular among fitness. These ergometers combine the use of upper or lower limbs while remaining seated. Its characteristic is that of a system of external load imposed through air resistance which increases with the cadence imposed on the equipment. The present study aimed to evaluate the reliability of the ramp test and standard leg-cycle ergometer to assess maximum oxygen uptake (VO2max). For this purpose, 18 physically active young men, aged between 19 and 29 years (mean ± standard deviation= 21.78 ± 2.44), performed three maximal incremental ramp tests in random order: one test on a cycle ergometer and two tests on an Air Bike arm- and leg- ergometer (test and re-test) with cardiorespiratory measurements throughout the tests. VO2max and maximum heart rate (HRmax) were significantly higher in the Air Bike compared with the cycle ergometer (53.06 ± 8.72 vs 47.38 ± 9.15 mL/min/kg), 181.93 ± 10.20 vs 176.07 ± 5.28 bpm, p< 0.001; 95%CI 3.41-7.95; ES= 0.30 and p= 0.01; 95%CI 1.44-10.29; ES= 0.34, respectively for VO2max and HRmax). There were no differences between the two ergometers in the maximum respiratory exchange ratio (RER) and test duration (1.21 ± 0.13 vs 1.21 ± 0.13, 598.06 ± 37.28 vs 612.22 ± 86.40 s, p= 0.9; IC95% -0.05 - -0.05; ES= 0 and p= 0.4; 95%CI -46.12-17.79; ES= -0.11, respectively for RER and test duration). Both VO2max and HRmax showed to be reliable when assessed with the Air Bike ergometer. The maximal test carried out on the Air Bike is a reliable ergometer to assess VO2max and probably enables a higher VO2max as compared with a standard leg-cycle ergometer. [ABSTRACT FROM AUTHOR]

Drowning is responsible for about 372000 deaths per year around the world (OMS, 2014). Nowadays, Swimming Instruction is considered a relevant preventive measure for drowning. However, the act of swimming by itself does not ensure the victim full protection; thereby, this study embraces the concept of Water Competency because it includes swimming competencies, awareness, attitude and risk management. Based on a series of studies called "Can you Swim? Survey" (Moran et al., 2012), it was established an evaluation protocol on Perceived Water Competency (PWC), Real Water Competency (RWC) and Risk Management (RM) adapted to the Portuguese reality, focused especially in the Azorean educational context. Aside from these competencies evaluation, the protocol also describes the environmental and sociocultural influences and the Physical Education subject and Sports on the development of water competencies. This work aims to bridge the gap of a standard evaluation methodology of Water Competency (WC). Adding a set of tasks and an effective review of the obtained results, the present methodology allows the classification of groups of students into approved/not approved as an essential precondition of the activities/categories' safe execution in the nautical area. It also presents a dissemination of the tools constructed and established partnership's methodology. A pilot application was carried out in a group of students (n = 115) with an average age of de 14.58 years for both genders. This test sample belongs to six geographically balanced schools in São Miguel Island -- Azores. The obtained results suggest that participants in this study were unable to accurately predict their actual swimming and survival skills, and no significant differences were evident in perceived or actual competency by gender. It was proven that regular informal exposure affects some of the tested competencies. However, the Physical Education classes swimming lessons variable was responsible for the bigger differences. In the end, we checked that formal Competitive Swimming lessons are the variable that shows a bigger influence in the PWC, in particular on the perceived activities of "maximum distance swam in 15 minutes" (Mann-Whitney U = 739, p = 0.000), "100 m backstroke" (Mann-Whitney U = 699, p = 0.000) and "dive entry headfirst" (Mann-Whitney U = 963, p = 0.010); in RM on the: "caught in a rip current at beach" (Mann-Whitney U = 972.5, p = 0.029) and "chased toy into the deep end of a swimming pool" (Mann-Whitney U = 957, p = 0.022); and in RWC on the activities: "maximum distance swam in 15 minutes" (Mann-Whitney U = 777, p = 0.000), "underwater swimming" (Mann-Whitney U = 963.5, p = 0.023), "100 m backstroke" (Mann-Whitney U = 712, p = 0.000) and "2 m surface dive" (Mann- Whitney U = 921.5, p = 0.012). Thereby, when having a major exposure combined with organised water safety or swimming lessons, the RWC increases. This work highlights the importance of proper conditions to maximise exposure and aquatic education amongst young people, leading to the prevention of drowning. [ABSTRACT FROM AUTHOR]

The present study aimed to assess the precision of oxygen uptake with heart rate regression during treadmill running in highly trained runners. Twenty national and international level male runners were divided into two equal groups. Group A was formed of 10 sprinters (31.5± 4.7 years, height 1.74± 0.04 m and mass 61.8± 5.2 kg), and group B comprised 10 endurance runners (25.7± 4.5 years, height 1.77± 0.08 m and mass 71.2± 5.8 kg). Each participant performed six min bouts at a constant velocity on a level treadmill, with each bout at an increased running velocity. The starting velocity was 3.33 m·s-1, with a 0.56 m·s-1 increase in each subsequent bout. VO2 and HR were measured during all runs. Mean peak VO2 and mean peak HR for Group A were, respectively, 71.7± 7.0 mL·kg-1·min-1 and 179.8± 12.7 beats·min-1, while for Group B were 67.3± 4.9 mL·kg- 1·min-1 and 198.2± 9.8 beats·min-1. The linearity of the regressions between VO2 and HR in both groups was very high (R2= 0.97 and R2 =0.76) with small standard errors of regression. Despite a stronger correlation in endurance-trained athletes, the results of the present study indicate that it is possible to use HR as an indicator of exercise intensity in individuals trained in both speed and longer distances.

Mean propulsive velocity (MPV) has been associated with neuromuscular fatigue; however, its suitability for strength training in Paralympic powerlifting (PP) remains uncertain. The objective of this work was to evaluate the MPV in two training methods (traditional-TRAD and eccentric-ECC). Eleven PP athletes were evaluated pre, during the intervention and post intervention at a load of 80% of the 1RM for TRAD and 110%-80% of 1 RM for ECC. The results demonstrated that there was no significant neuromuscular fatigue for the TRAD (~5% performance loss), as well as no significant decline in MPV during the intervention. For the ECC, there is a significant reduction in MPV before and after training (~12% loss of performance). A difference between TRAD and ECC after the intervention was also identified (0.87 m/s±0.22, 95% CI 0.72-1.02 vs. 0.72±0.20, 95% CI 0.59-0.86 p=0.042, F(3.30)=10.190, η2p=0.505 - very high effect). During the intervention for ECC, no significant decline in MPV was observed. The results of this study suggest that the mechanical indices of MPV do not seem to be effective indicators of neuromuscular fatigue in the sample studied or in the context of this specific training regime, being more indicated as a control of training volume., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest., (The Author(s).

Introduction: The aim of this study was to explore which key somatic features are common to four swim strokes and medley, and specifically to identify which characteristics benefit only specific strokes., Methods: The sample was composed of 130 swimmers (95 males aged 19.5 ± 2.9 years and 35 females aged 18.4 ± 2.8 years). A set of anthropometric variables was used to predict swimming speed in the four swimming strokes and medley., Results: A multiplicative model with allometric body size components was used to identify the demographic and anthropometric predictors of swimming speed. Trunk height and waist circumference were the only variables significantly different among swimming strokes ( p  < 0.05). Associations between swimming speed and arm length were similar in breaststroke and medley, and in freestyle, backstroke and butterfly ( R 2  = 60.9%). The model retained as swimming speed predictors the age 2 , upper body circumference, hand breadth, waist circumference, and subscapular skinfold thickness (these last two had negative associations)., Conclusion: All these predictors were common to all four swim strokes and medley. Arm length was also retained as a significant predictor, but this one varied significantly between the four different swim strokes and medley. These findings highlight the importance of having a "V-shape" trunk, longer upper limbs, and large hands as predictors of swimming performance., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Rejman, Nevill, Garrido, Rudnik and Morais.)

Background: Agility, vertical jump (VJ), and shot velocity (SV) are associated with water polo (WP) performance. The aim of this study was to identify the performance in agility, VJ and SV; to verify the correlations between the variables; and to identify the 90 th and 95 th percentile of each variable., Methods: Fifty-five male WP players (aged 21.6±8.2 years; experience in WP: 8.5±6.1 years) were assessed in three specific in-water tests: 1) Functional Test for Agility Performance; 2) VJ; 3) SV. The 95 th and 90 th percentiles were identified (5% and 10% best results). Correlations were tested with Pearson Correlation test., Results: Agility, VJ, and SV, were, respectively: 3.8±0.3 s; 137.5±14.3 cm; and 17.9±1.4 m·s -1 . For the 95 th percentiles, nine players were identified, all different players, three at each parameter. For the 90 th percentile, 16 players were included, but just one player ws in the 10% best result for the three variables. Correlations (P≤0.05) were found for agility vs. VJ (r=-0.38) and for agility vs. SV (r=- 0.25)., Conclusions: Although correlations have been found between the variables, it was not possible to verify the pattern of better players in the three parameters evaluated.
