Our study�s goal was to underline the differences between the girls� and the boys� representative in terms of age, in what concerns the moving speed and the effort perception during the dynamic balance when walking on the slackline throughout the activities specific for the Development through Education and Adventure (DEA). The results have shown the fact that the boys have a better speed movement on the slackline rather than the girls, allowing us to conclude that the boys� dynamic balance is superior to the girls� balance on both studied age categories. Perceiving the physical effort through heart rate is different according to age category when walking on the slackline for the groups of the study.

AbstractBackground: The purpose of the following research was to find out the influence of imaginary training based on intention implementation on throw effectiveness of young basketball players, both male and female in stressogenic situations. Individual differences (action vs state orientation) between players were also measured in this research.Material/Methods: 76 players (32 females and 44 males) in the cadet category (15-16 years old) from basketball clubs of Gdansk, Gdynia and Sopot took part in this research. In the first stage all players did a throw efficiency test ERPE 05 under two conditions, and their heart rate was measured. Then players were randomly assigned to one of two groups. The first one did imaginary training based on the influence of intention implementation for 10 days, while the other did not. After 10 days ERPE 05 test under two conditions was run again.Results: Test results showed that intention implementation does not influence effectiveness improvement in stressogenic conditions as far as state-oriented players are concerned, but it does lower the physiological cost of physical effort in form of a decreased heart rate.Conclusions: This research proves that visualization training based on implementation instructions does influence young players’ physiology and significantly lowers their heart rate under stressogenic conditions. However useful, visualization techniques used in this research still need other tests and should be applied for a longer period of time to acutely show how they affect young players’ mental preparation

Summary Study aim: the objective was to assess and compare the energy expenditure (EE) and exercise heart rate (EHR) during Nordic Walking (NW), and conventional walking (W) in physical education and tourism/recreation university students. Material and methods: a total of 53 women and 65 men, students at the Academy of Physical Education in Katowice, and Polytechnic in Opole, in Poland, were investigated to assess the EE of Nordic Walking and conventional walking, and to measure the EHR, a uniaxial accelerometer – Caltrac Monitor, and a pulsometer – Polar RS 400 SD were used. After a standard warm-up, the participants (joined group) were marching with poles for 30 minutes, at a speed regulated by the group’s leader, who used footpod’s indications: 5.5–6.5 km/h – in Katowice, and 7.5–8.5 km/h – in Opole. After a break, during which the participants’ heart rate decreased below 100 bpm, the above actions and measurements were repeated, during normal walking. Results: energy expenditure during Nordic Walking (EE NW), expressed in kcals and METs, was in women and in men, at both analyzed speeds, significantly higher (p < 0.05) than during conventional walking (EE W). EHR was higher during NW, compared to W, and the statistically significant differences were revealed both in female’s and male’s groups. Conclusions: our study data have shown that EE and EHR during Nordic Walking, have been significantly higher than during conventional walking, regardless of the moving speed and gender. NW might present a useful modality in prevention of hypokinetic disorders.

AbstractPurposeThe present study aimed to compare the physiological responses of high-intensity race-pace continuous vs. interval workouts commonly used in middle-distance athletics, by means of analyzing post-exercise cardiac autonomic regulation and lactate.MethodsNineteen highly-trained 800-m male runners were asked to run a 600-m race-pace continuous workout and a 2 × 4 × 200-m interval training, counterbalanced and randomized within one week of difference. Blood lactate jointly with linear and nonlinear heart rate dynamics were assessed during the immediate 15-min recovery. Age-category (Under23-Senior vs. Juvenile-Junior) was considered as an inter-subject factor.ResultsPeak lactate was higher following the interval training (15.51 ± 0.99 vs 13.83 ± 1.77 mmol L−1; P < 0.05) whereas lactate removal was almost nonexistent 15 min after both workouts (between 0 and 16%). Vagal modulation (ln RMSSD and lnRMSSD to RR ratio) remained significantly depressed at the end of recovery following both workouts, although the alteration was larger following the interval training. Detrended Fluctuation Analysis evidenced a more random HR behavior (DFA1 closer to 0.5) during the first 9 min of recovery after the interval training, whereas no significant change was observed in heart rate complexity (SampEn). Neither were differences found in post-exercise lactate and HR dynamics as a function of age-category.ConclusionsHigh-intensity workouts commonly used in middle-distance athletics, both race-pace continuous and intervallic approaches, induce a large depression of vagal modulation in highly trained runners, although interval trainings appear to induce even a greater alteration of both linear and nonlinear HR dynamics and a higher post-exercise peak lactate.

Abstract Introduction: Since strength and endurance training has become very popular, we aimed to assess the possibility of hypoxemia determined in peripheral blood during exercise, starting from the hypothesis that a relatively large muscle mass would have a protective effect. Aim: Hypoxemia can cause serious illness and therefore we consider it useful to investigate the occurrence of this phenomenon during exercises of strength or endurance. Methods: The preliminary study was conducted on 8 subjects, both trained and untrained. With a Beurer pulse oximeter, heart rate and oxygen saturation of the capillary blood were measured before, during, and at the end of strength, or endurance or endurance combined with strength training. Results: The results have shown that hypoxemia occurs only under the conditions of high intensity training, which alternates endurance with strength exercises, simultaneously with decreasing heart rate, only in trained subjects and with relatively low muscle mass. Conclusions: The decrease in oxygen saturation in the peripheral blood occurs simultaneously with that of heart rate and it seems that large muscle mass has a protective effect on oxygen desaturation.

AbstractThe aim of this study was to evaluate the reproducibility of the heart rate variability threshold (HRVT) by different HRV indexes and determination criteria. 68 untrained participants, 17 women (24.09±4.91 years old; 21.54±1.97 kg∙m−2) and 51 men (24.52±3.52 years old; 26.51±6.31 kg∙m−2), were evaluated on 2 different days (test and retest). The HRVT was determined during an incremental exercise test using 2 indexes (SD1 and RMSSD) and criteria (HRTV1, first intensity of physical effort with index<3 ms, and HRVT2, first intensity of physical effort, in which the index presents a difference<1 ms between 2 consecutive intensities). There was no significant difference (p<0.05) between the test and retest for any of the variables evaluated. All variables, except for the rate of perceived exertion at HRVT2, presented moderate to high intraclass correlation coefficient (HRVT1: 0.55–0.85 and HRVT2:0.58–0.69). All variables at HRVT1 and the heart rate at HRVT2 showed coefficient of variation ~ 10%. The HRVT, regardless of criteria and HRV index used, showed satisfactory reproducibility. Thus, these criteria can be used to assess clinically autonomic cardiac modulation and aerobic capacity, and to analyze the effect of different interventions.

The goal of the training is to enable the body to perform prolonged physical effort without reducing its effectiveness while maintaining the body’s homeostasis. Homeostasis is the ability of the system to maintain, in dynamic balance, the stability of the internal environment. Equally as important as monitoring the body’s thermoregulation phenomena during exercise seems to be the evaluation of these mechanisms after physical effort, when the athlete’s body returns to physiological homeostasis. Restoring homeostasis is an important factor in body regeneration and has a significant impact on preventing overtraining. In this work we present a training protocol using a rowing ergometer, which was planned to be carried out in a short time and which involves working the majority of the athlete’s muscles, allowing a full assessment of the body’s thermal parameters after stopping exercise and during the body’s return to thermal equilibrium and homeostasis. The significant differences between normalized mean body surface temperature obtained for the cyclist before the training period and strength group as well as before and 10 min after training were obtained. Such observation seems to bring indirectly some information about the sportsperson’s efficiency due to differences in body temperature in the first 10 min of training when sweat does not play a main role in surface temperature. Nearly 1 °C drop of mean body temperature has been measured due to the period of training. It is concluded that thermovision not only allows you to monitor changes in body temperature due to sports activity, but also allows you to determine which of the athletes has a high level of body efficiency. The average maximum body temperature of such an athlete is higher (32.5 °C) than that of an athlete who has not trained regularly (30.9 °C) and whose body probably requires further training.

Abstract: The objective of the elaboration was to assess the degree of physical load in direct start preparation (DSP) during preparations of disabled sitting volleyball players for the Polish championships.: Players of the “Start” Sports Club of the Disabled in Wroclaw who play sitting volleyball professionally participated in the study. The subjects of the study were men aged 17 to 53 (average age: 31.9); they have been playing sitting volleyball for 2.5 to 33 years. Twelve sitting volleyball players with various disabilities concerning uni- and bilateral amputation within the lower leg and thigh, with malformation and short lower limbs participated in the study.: The study involved assessment of the exercise capacity of sitting volleyball players during 7 training units in introductory and intensifying micro-cycles within DSP. Heart rate results at six moments (at the beginning, in the 10: Years of training significantly correlated with age of the participants. The participants were characterized by significantly lower resting heart rate in the intensifying micro-cycle than in the introductory microcycle which may result from adaptation of the body to physical effort. The largest differences in average heart rate values at the considered moments of training units in training micro-cycles within DSP were observed in the measurement of resting heat rate and final heart rate. Standard deviation in the introductory micro-cycle and the intensifying micro-cycle within DSP was growing in a linear manner, except for the peak heart rate index. Resting heart rate significantly impacted the value of heart rate during training units within DSP.Volleyball players participating in the study were characterized by significantly lower resting hear rate in the intensifying micro-cycle than in the introductory micro-cycle within DSP which may result from adaptation of the body to physical effort. The lowest percentage difference of the average heart rate value occurred in the assessment of final heart rate, while at the remaining moments of training units heart rate values reached the same percentage value. The course of regeneration in both compared micro-cycles (DSP) was similar and it did not vary significantly. Restoring the value of resting heart rate occurred after more than 15 minutes after training.

Beer Consumption

Background and objectives: Beer consumed in moderation (330 mL/day for women and 660 mL/day for men, up to 5% alcohol) may have certain benefits for the human body, due to natural ingredients, but especially due to important sources of protein, fiber and antioxidants. According to specialized studies, beer consumed in moderation can have beneficial effects on the body. Materials and methods: The study was conducted on 50 subjects selected based on characteristics such as age, height, weight and not after exercising or doing physical activities. All research subjects benefited from two evaluations (initial and final), consisting of: physical examination, EKG examination, body hydration analysis, adipose tissue analysis, muscle tissue analysis, heart rate analysis and speed motor quality. These analyses were performed daily for a period of seven days, both for the initial and the final evaluation (a total of 14 days of assessments). Results: Between the two evaluations, subjects consumed 660 mL of beer with up to 5% alcohol daily (WHO recommended dose) for 30 days. The results obtained (at the initial and final evaluation) were inventoried and statistically processed using statistical programs. It was found that moderate beer consumption (660 mL of beer with up to 5% alcohol) daily for a period of 30 days can lead to an increase in body hydration, a decrease in adipose tissue as well as an increase in muscle mass. In addition, a decrease in heart rate was observed after physical activity (short running on 100 m), which leads us to a better adaptation of the body after intense physical effort. Discussion and conclusion: Moderate beer consumption (660 mL/day for men, up to 5% alcohol, WHO recommended dose) can have beneficial effects on body hydration, adipose and muscle tissue, and better adaptation of the body after intense physical effort.

The Relationship

Evaluation of a person's overall physical effort has traditionally been performed by measuring such easily quantifiable parameters as heart rate and oxygen consumption. Electromyography of a particular muscle, while being an acknowledged indicator of the amount of effort of that muscle, may not necessarily be an indicator of overall physical effort. Research conducted in recent years tends to show that mild stress changes were reflected in the EMG of the frontalis. This study is an attempt at seeking a relationship between the EMG of the frontalis and the workload. Heart rate and frontalis EMG were recorded at three different rates of work. Results indicate that the relationship between workload and heart rate is significant, while that between workload and frontalis EMG is not significant.
