Comprehensive and special physical fitness of judo athletes of provincial national teams in the age groups: youngster (U16) and junior (U21)

The research aimed to determine the relationship between the universal and special physical fitness of judoists. The study involved players from the youngster (U16) and junior (U21) age group from provincial teams. The International Physical Fitness Test was used to measure comprehensive fitness, and the Special Judo Fitness Test was applied to assess special fitness. The research has shown that juniors exhibit a higher level of all-round (excluding flexibility) and special fitness than youngsters. More relationships between comprehensive physical fitness and special fitness were demonstrated in the youngster group. Leg muscle strength, endurance, agility, and abdominal strength were found to have the most significant impact on the overall level of all-round fitness in the youngster age group, while in the age group under 21, endurance, hand strength, and arm strength had the most significant impact. It has been shown that the combination of individual components of versatile fitness in a given training cycle may bring positive effects in shaping those features in both age groups. Besides, it has been shown that when taking account of the athlete’s ontogenetic development and his/her sensitive period, the relationships between the components of comprehensive fitness and comprehensive and special fitness can significantly affect the effectiveness of the training process in both age groups.

Assessment of the influence of physical activity and screen time on somatic features and physical fitness in 6 to 7-year-old girls

Aim of the study is to assess the relationship between screen time, physical activity and physical fitness among girls 6–7 years-old. 21,528 girls aged 6 and 7 from Poland were assessed in terms of physical fitness. Arm strength, abdominal strength and explosive strength of the lower limbs were measured using the EUROFIT test. Basic somatic features were measured and BMI and WHtR indices were calculated. Spontaneous and organized physical activities as well screen time were assessed by the parents utilizing a questionnaire. The multiple logistic regression method was used to evaluate the influence of screen time and spontaneous physical activity on various components of physical fitness. Physically active (PA) girls (≥1h/day) and those who participated in additional physical activities (APA) during the week had significantly higher height, weight, and BMI (p<0.001), but not WHtR. They had a higher level of flexibility, explosive strength of the lower limbs and arm strength (p<0.001). With an increase in screen time, the BMI, WHtR increased significantly and explosive strength of the lower limbs, abdominal strength and arm strength were lower. Regression analysis showed that more frequent participation in extracurricular activities increased the values of BMI and WHtR in quartile 4 (Q4), and strength components: Q2–Q4 (p<0.05). Spontaneous physical activity was positively related to the values of BMI, WHtR (both: Q4; p<0.05), explosive force of lower limbs (Q3–Q4; p=0.001), and negatively related to arm strength (Q2; p=0.001). Screen time (≥2hrs/day) increased odds for higher BMI values (p<0.05). Each screen time category decreased the odds of achieving abdominal muscle strength related to the quartiles: Q2–Q4 (p<0.05), arm strength (Q4: p<0.05). ST (1 <2hrs/day) decreased arm strength (Q3; p= 0.045). Our research has shown that screen time-related sedentary behavior and physical activity affect overweight and obesity indices (especially BMI) and strength abilities. The observed associations more often affected girls with a higher level of fitness The results observed in girls aged 6-7 indicate a need for early intervention aimed at limiting time spent watching TV and computer use, as well as to encourage both spontaneous and organized physical activities.

Fitness tracking reveals task-specific associations between memory, mental health, and exercise

Physical exercise can benefit both physical and mental well-being. Different forms of exercise (i.e., aerobic versus anaerobic; running versus walking, swimming, or yoga; high-intensity interval training versus endurance workouts; etc.) impact physical fitness in different ways. For example, running may substantially impact leg and heart strength but only moderately impact arm strength. We hypothesized that the mental benefits of exercise might be similarly differentiated. We focused specifically on how different forms of exercise might related to different aspects of memory and mental health. To test our hypothesis, we collected (in aggregate) roughly a century's worth of fitness data. We then asked participants to fill out surveys asking them to self-report on different aspects of their mental health. We also asked participants to engage in a battery of memory tasks that tested their short and long term episodic, semantic, and spatial memory performance. We found that participants with similar exercise habits and fitness profiles tended to also exhibit similar mental health and task performance profiles. These effects were task-specific in that different exercise patterns or fitness characteristics varied with different aspects of memory, on different tasks.

A novel human-robot interface based on soft skin sensor designed for the upper-limb exoskeleton

The upper-limb exoskeleton is capable of enhancing human arm strength beyond normal levels, whereas deriving the operator’s desired action straightforward turns out to be one of the significant difficulties facing human-robot interaction research. In the study, the human-robot interface was presented to regulate the exoskeleton tracking human elbow motion trajectory that employed the contact force signals between the exoskeleton and its operator as the primary means of information transportation. The signals were recorded by adopting the novel soft skin sensors attached to the bracket on the exoskeleton linkage, which could reflect the human arm motion intention through the virtual admittance model and adaptive control. Subsequently, a 1-DOF upper-limb exoskeleton was designed to illustrate the performance of the proposed sensor and the interaction control method in the human-robot cooperation experiment.

Effect of swearing on strength: Disinhibition as a potential mediator

Introduction: Swearing fulfils positive functions including benefitting pain relief and physical strength. Here we present three experiments assessing a possible psychological mechanism, increased state disinhibition, for the effect of swearing on physical strength. Method: Three repeated measures experiments were carried out with sample sizes N=56, N=63 and N=118. All three included the Balloon Analogue Risk Task (BART) to measure risky behaviour. Experiments 1 and 3 included measures of physical performance assessing, respectively, grip and arm strength. Experiment 3, which was pre-registered, additionally assessed flow, self-confidence, anxiety, emotion including humour, and distraction including novelty.Results: Experiments 1 and 3 found that repeating a swear word benefitted physical strength and increased risky behaviour, but risky behaviour did not mediate the strength effect. Experiment 2 showed no effect of listening to an audio track of a repeated swear word. Experiment 3 found that repeating a swear word increased flow, self-confidence, positive emotion, humour and distraction. Humour mediated the effect of swearing on physical strength. Discussion: Consistent effects of swearing on physical strength indicate that this is a reliable effect. Swearing affected several constructs related to state disinhibition including increased self-confidence. Humour appeared to mediate the effect of swearing on physical strength, consistent with a hot cognitions explanation of swearing-induced state disinhibition. However, as this mediation effect was part of an exploratory analysis, further pre-registered experimental research including validated measures of humour is required.

Enhanced Lipocontouring of the Arms

The visibility of arm contour in both men and women has been a source of discussion throughout time. Arm strength and athleticism is not limited to the male physique only. Iconic women such as Madonna and Michelle Obama have made discussions about arm contour more and more commonplace. Over the years arm contour has been a difficult area to address due to the thinness of the skin which often required surgical excision and unsightly scars. Liposuction of the arm has advanced to not only allow for improved contour but also options of refining muscular definition. With the addition of energy-based technologies such as radiofrequency, we can offer less invasive options to patients who may have previously only been candidates for excisional procedures. Liposuction of the arms can be performed under local anesthesia. This chapter introduces a new algorithm for assessment and treatment of arm contour which incorporates newer energy-based devices along with surgical options.

Effectiveness of Swimming Program in Adolescents with Down Syndrome

The aim of this study was to estimate the influence of a 33-week swimming program on aerobic capacity, muscle strength, balance, flexibility, and body composition of adolescents with Down syndrome (DS). Twenty-two adolescents diagnosed with DS were randomly allocated into the training group (T) and the control group (C). The T group participated in 33 weeks of water-based exercise and a swimming program while the control group maintained their normal daily activity. Following thirty-three weeks of swimming program, body mass, body fat, and BMI of the T group decreased significantly (from 56.8 ± 7.97 kg to 55.0 ± 7.11 kg, from 15.1 ± 4.47 kg to 13.2 ± 3.92 kg, and from 25.1 ± 2.37 to 24.0 ± 2.05, respectively) while a significant increase was recorded in C (from 57.3 ± 8.43 kg to 59.7 ± 8.29 kg, from 14.5 ± 2.76 kg to 16.0 ± 3.11 kg, and from 25.4 ± 2.46 to 26.0 ± 2.72, respectively). Moreover, significant improvement in aerobic capacity in the T group was noted; VO2max (mL/kg/min) increased by 16.3% in T and decreased by 4.8% in C. Improvement in static arm strength, trunk strength and endurance/functional strength were noted in T, while the parameters did not change in C. The speed of arm movement, balance and flexibility did not change following the intervention. Also, the aquatic skills improved significantly in the training group. Changes in C were not significant. The results of our study indicate that 33-week swimming program significantly improved health status and swimming skills in adolescents with DS.

The population in this study were all 5 athletes of Speed FPTI Binjai, consisting of 4 men and 1 woman. Determination of the sample in this study using total sampling technique, so that the entire population sampled as many as 5 athlete. The variables in this study are arm strength (X) and climbing speed (Y). Data collection methods used were tests and measurements. The measurement of arm strength with a push and pull dynamometer and a climbing speed test is carried out by the athlete climbing as high as 15 meters. The data obtained were analyzed using simple linear regression techniques. The results showed that (1) The arm strength Speed athlete FPTI Binjai had an average of 18.00 and SD (Standard Deviation) was 5.52, with the highest score of 26 kg (20%), while the lowest score was 11 kg (20%). (2) The speed of climbing Speedathlete FPTI Binjai has an average of 12.48 with SD (Standard Deviation) of 5.57, in the sense that the average speed of the athlete to the top is 12''48, with the fastest time of 8 '. '23 (20%), while the longest time is 22''24 (20%) (3) The relationship between arm strength and rock climbing speed can be described from the regression equation obtained, namely Y = 25.301 + 0.278X. Based on the regression equation obtained, it can be explained that every time there is an increase in arm strength by 1%, it will increase the speed in rock climbing by 0.278 points. The relationship between arm strength and rock climbing speed is in a very strong category because the coefficient of determination is 99.7% while 0.3% is caused by other factors. Based on the F test conducted by comparing Fcount with F table, it is obtained, Fcount = 296.64, while Ftable = 7.71 with a significance level of α = 0.05. By comparing Fcount = 296.64> 7.71, it means that there is, from calculations using SPSS, a significance figure of 0.003 is obtained. So that 0.003 <0.05, then H0 is rejected and H1 is accepted, meaning that there is a relationship between arm strength and rock climbing speed for Speed FPTI Binjai athletes.
