    The beginning of Covid 19 and the establishment of restrictions to curb the development of the pandemic on the territory of Latvia have led to the changing of the lives of the youth, including their physical exercise and study habits and practices. This article investigates the role of physical activities training for young males and females and their choice of teaching platforms by different genders. The study methodology encompasses critical examination of previous research conducted on Generation Z, gender differences and the significance of physical exercise and sports in for the youth combined with statistical evaluation and assessment of primary survey data. Compare with previous articles this article is constituted by its identification of the way in which gender differences influenced changes in physical activity and in which attitudes towards healthy lifestyles and physical activity changed before and during the COVID-19 pandemic. The authors of the study observed substantial differences between the answers of males and females about their health before and during the pandemic, with Independent Samples t-Test (p=0,03) and (p=0,025), which is likewise confirmed by the answers about the presence of depressive moods, which are more pronounced in females (p=0,004). In assessing the difference between males and females in the area of physical activities, differences were observed both before and during the pandemic (p=0,001) and (p=0,005), with females doing less physical activities than males both before and during the pandemic. To direct their physical activities, females are more likely to engage an instructor or attend training sessions via special platforms than males (p=0,001). In examining the most popular applications and platforms for teaching physical activities, no substantial difference was observed in their use between the two genders.

    In sprint distance probably the most important factor for a good result is the athletes achievements in power of cycling, because the athletes, who ride with a very high frequency, but cannot put in a cycle solid force in competitions. Consequently is need for new resources or means to increase the strength expressions, to be able to compete successfully with highlevel athletes. One of such is the local vibration. In our study we use the local vibration in development of cyclists strength expressions and power the aim of study is to determine influence of local vibration on cyclists peak anaerobic power. The subject of study is 15years old 2 cyclists. To carry out experiment, we arranged both cyclists, was made an anaerobic power test, when the athletes were given an unlimited time to warm up and achieve the highest possible power. Maximum power test results before the local vibration showed that the average power of the test group was 906 W, after application of local vibration peak power was 975W. A study has confirmed our allegation that application of local vibration can significantly improve the results of sprint cycling. Local vibration as an innovative training mean has proved its reliability in training process, as the random-level athletes improve their anaerobic power.

    Introduction. Fundamental motor skills (FMS) are a critical component of success in various sports and lifelong physical activity (PA). This study aimed to evaluate and compare the FMS proficiency levels of 7-9-year-old children from Poland and Latvia, providing insights into the current state of motor competence in these populations. Material and Methods. A cross-sectional study design was utilized, incorporating a sample of 163 boys and girls. The FUS test (Fundamental Motor Skills in Sport), a comprehensive, qualitative, and process-oriented assessment tool was used to assess FMS. The FUS test encompassed a range of movement tasks, including hurdles, jumping rope, forward roll, ball bouncing, ball throwing and catching, and kicking and stopping a ball that allows for a thorough evaluation of FMS proficiency. Results. The study revealed alarmingly low FMS proficiency levels in both countries, with 93.3% of students displaying 'insufficient FMS proficiency'. The Mann-Whitney U test showed that Latvian boys outperformed their Polish peers in jumping rope and forward roll (p < 0.05), while Polish boys exhibited superior results in kicking and stopping a ball (p < 0.05). In contrast, Polish girls achieved significantly higher scores in hurdles and kicking and stopping a ball (p < 0.05) compared to Latvian girls, who scored higher in jumping rope (p < 0.05). Conclusions. These findings highlight the urgent need for effective, evidence-based interventions to improve motor competence in both countries, emphasizing the importance of incorporating FMS development into physical education curricula and promoting regular PA for children.

    Lokālās vibrācijas ietekme uz anaerobo jaudu un anaerobo jaudas kapacitāti airētājiem. Promocijas darba kopsavilkums / Effect of Local Vibration on Power Anaerobic Power and Anaerobic Power Capacity. Summary of the Doctoral Thesis
    (Latvian Academy of Sport Education, 2013) Ciekurs, Kalvis; Krauksts, Viesturs
    In rowing, as in any sport, dominant physical abilities, necessary for the definite sport, are emphasized. In rowing the basic physical abilities are endurance and strength, although recently it is also much spoken about the speed ability. Definitely, also coordination is a very significant physical ability in rowing. It is much spoken about and researched how to increase the speed of moving in rowing. The equipment is being improved, it is made of different fusions of plastic and metal which are more durable and easier. Today the athletes of Latvia have high results, and, sure, if their boats are similarly prepared, the winner is the one who has higher rowing technical preparation (synchronisation in double, quadruple and eight sculls), physical conditioning and psychological preparation, as well as a coach’s work is a very essential aspect. As one of the ways how to solve the problem local vibration application before and after competitions, as well as during training sessions, is offered. Many scientists as Kleshnev V. (Kleshnev V. 2010, 2011), Hawkins D. A. (Hawkins D. A. 2000), Hofmijster M. (Hofmijster M. 2010), Nolte V. (Nolte V. 2011), Nilsson J. (Nilsson J. 1977), a.o. have researched the possibilities of increasing the speed of moving in rowing. Most part of researches is based on oxygen maximal consumption and other physiological changes during a load. Although there are various researches, stating the technical nuances of leg and arm work, comparatively little attention is paid to the role of the arm work. The cycle length in different distances and having different water flow – before the wind, against the wind and with the side wind is stated. In the world full body vibration is applied as one of the parts of innovative training means, it helps athletes faster get renewed and prepare for a new training. However, less attention is paid to the effect of local vibration which is applied to a definite part of the body, muscle or muscle part. In sport mechanical vibrations are used as a means of massage and as a kind of training. For many years vibration trainings are used as a training means, and earlier it had only two types of tasks: vibration stimuli were applied to increase strength, and using vibration they rather successfully increased separate motor ability or physical work capacity on the whole body vibration platforms. If vibration as a kind of massage and a means of rehabilitation has been known for many thousands of years, than vibration as a training means is known not long ago. Scientists relatively long ago have stated that in sport vibration actually has two way effect: the first is linked with acute or immediate effect, but another – with long-term or chronic effect which today is called as vibration trainings realised with the same conditions as all other means in sport. The attempts to combine vibration loads with traditional strength trainings with the purpose to achieve greater increase of the work capacity of the neuromuscular system than only using classical strength trainings have already been carried out comparatively long ago. Recent research gives notion about the fact that vibration trainings both in acute or chronic form have explicitly positive effect on strength and power expressions in athlete whole preparation process. If it is considered that vibration is a constant component of a training means, then vibration effectiveness in strength and power expressions, and not only, depends on vibration load characteristics, and they are as follows: a kind of vibration realisation or application, the frequency of oscillation waves and amplitude. The classical load formation regularities – a kind of training, intensity and amount have an essential role, too. Vibration frequency and amplitude are load effect values with what vibration affects the neuromuscular system with the purpose to improve an athlete’s body ability to increase the total work capacity. It is already proved in many scientific conclusions that as a result of the vibration training not only strength and power expressions increase, but also flexibility or movement amplitude, movement coordination, balance successfully improve, movement and moving speed increases, athletes’ ability to focus attention on training loads and competition activity increases. However, at the present stage of the research process scientists have made the main conclusion that for the present the vibration trainings give the best effect in the field of strength and power expressions. It is pointed out in the scientific publications that the vibration frequencies of 30-50 Hz range have the greatest effectiveness on the neuro-muscular system (to optimise strength and power expressions). Only vibration platforms, where only the whole body vibration which is considered as the vibration of indirect effect is provided, can give the frequencies of such a range. It has smaller effectiveness than the direct or local vibration, where vibration is applied to definite muscle or its tendon, and it has essentially bigger effectiveness. In the case of the direct or local vibration the vibration frequency is significantly bigger (>100 Hz), but the amplitude is smaller (1-4 mm). So, each of these various vibration forms affect muscles in different way, and wherewith vibration has different effect on training effectiveness. To get greater effect in strength and power development, it is not enough to increase the intensity and amount of vibration loads used in trainings or to increase vibration frequency and amplitude (Krauksts V., Ņemčenko A. 2011). Firstly, excellent general and special physical condition should be provided then in the training process vibration should be included as a means of training. To state every athlete’s individual methodology of vibration trainings during the application of vibration it is necessary to observe the athlete and communicate with him/her. Although the methodology of vibration trainings is worked out the same for all athletes, the strength of vibration application is different.

    Lokālās vibrācijas ietekme uz anaerobo jaudu un anaerobo jaudas kapacitāti airētājiem. Promocijas darbs
    (Latvijas Sporta pedagoģijas akadēmija, 2013) Ciekurs, Kalvis; Krauksts, Viesturs
    Jebkurā sporta veidā, arī airēšanā, tiek izvirzītas dominējošās fiziskās spējas, kuras ir nepieciešamas attiecīgajam sporta veidam. Airēšanā pamata fiziskās spējas ir izturība un spēks, lai gan pēdējā laikā daudz tiek runāts arī par ātruma spējām. Protams, arī koordinācija ir neiztrūkstoša fiziskā spēja, kas ir ļoti nozīmīga airēšanā. Daudz tiek runāts un pētīts, kā palielināt pārvietošanās ātrumu airēšanā. Tiek uzlabots inventārs, kas pilnībā tiek gatavots no dažādiem plastmasas un metāla sakausējumiem, kas ir izturīgāki un vieglāki. Latvijas sportistiem šobrīd ir augsti rezultāti, un protams, pie vienādi sagatavotām laivām uzvarēs tas, kam airēšanas tehniskā (sinhronizācija pāru laivās, četru airētāju laivās, kā arī astoņu airētāju laivās), fiziskā un psiholoģiskā sagatavotība būs augstāka, un būtisks aspekts ir arī treneru darbs. Kā vienu no risinājumiem piedāvā izmantot lokālo vibrāciju pirms un pēc sacensībām, un arī treniņu nodarbību laikā. Daudzi zinātnieki kā (Kleshnev V. 2010, 2011.), (Hawkins D. A. 2000.), (Hofmijster M. 2010), (Nolte V. 2011.), (Nilsson J. 1977.), u.c. pievērsušies pārvietošanās ātruma palielināšanas iespējām airēšanā. Lielākā daļa pētījumu tiek balstīti saistībā ar skābekļa maksimālo patēriņu un citām fizioloģiskām izmaiņām slodzes laikā. Lai gan veikti dažādi pētījumi, nosakot kāju un roku darbības tehnikas nianses, samērā maz uzmanības veltīts roku darbības lomai. Tiek noteikts cikla ilgums dažādās distancēs ar dažādu ūdens plūsmu, pa vējam, pret vēju, ar sānvēju. Kā viena no inovatīvām treniņu līdzekļa sastāvdaļām pasaulē tiek izmantota pilna ķermeņa vibrācija, kas palīdz sportistiem ātrāk atjaunoties un sagatavoties jaunam treniņam. Taču mazāk uzmanību pievērš lokālas iedarbības vibrācijai, ko pieliek konkrētai ķermeņa daļai, muskulim vai muskuļa daļai. Sportā mehāniskās vibrācijas izmanto kā masāžas līdzekli un kā treniņu veidu. Jau daudzus gadus vibrācijas treniņus izmanto kā treniņu līdzekli, un agrāk tai atvēlēja tikai divu veidu uzdevumus: vibrācijas stimulus izmantoja spēka palielināšanai, un ar vibrāciju diezgan sekmīgi palielināja atsevišķas motorās spējas vai fiziskās darbspējas ar visa ķermeņa vibrācijas platformām. Ja vibrācija kā masāžas veids un rehabilitācijas līdzeklis bija zināma jau daudzus tūkstošus gadu, tad vibrācija sportā, kā treniņu līdzeklis pavisam nesen. Zinātnieki jau samērā sen ir konstatējuši, ka vibrācijai sportā faktiski ir divu veidu iedarbības formas: pirmā ir saistīta ar akūto vai nekavējošo iedarbību, bet otra ar ilgtermiņa vai hronisko iedarbības variantu, ko mūsdienās sauc par vibrācijas treniņiem, kurus realizē ar tādiem pašiem nosacījumiem, kā visus pārējos sportā realizētos līdzekļus. Jau samērā sen ir veikti mēģinājumi kombinēt vibrācijas slodzes ar tradicionālajiem spēka treniņiem ar mērķi sasniegt lielāku neiromuskulārās sistēmas darbspēju izaugsmi nekā tikai ar klasiskajiem spēka treniņiem. Pēdējo gadu zinātniskie pētījumi dod priekšstatu tam, ka vibrācijas treniņiem kā akūtā, tā arī hroniskā veidā ir izteikti pozitīva ietekme uz spēka un jaudas izpausmēm atlētu kopējā sagatavošanas procesā. Ja jau uzskata, ka vibrācija ir patstāvīga treniņu līdzekļa komponente, tad vibrācijas efektivitāte spēka un jaudas izpausmes jomās, un ne tikai, ir atkarīga no vibrācijas slodzes raksturlielumiem, un tie ir: vibrācijas realizācijas vai pielikšanas veids, oscilācijas viļņu frekvence un amplitūda. Būtiska loma ir arī klasiskajām slodzes veidošanas likumsakarībām – treniņu veidam, intensitātei un apjomam. Vibrācijas frekvence un amplitūda slodzes ietekmes lielumu ar kādu vibrācija iedarbojas uz neiromuskulāro sistēmu ar mērķi uzlabot atlēta organisma spēju palielināt savas kopējās darbspējas. Jau daudzās zinātniskajās atziņās ir pierādīts, ka vibrācijas treniņu rezultātā uzlabojas ne tikai spēka un jaudas izpausmes, bet veiksmīgi uzlabojas arī lokanība vai kustību amplitūda, kustību koordinācija, līdzsvars, palielinās arī kustību ātrums un pārvietošanās ātrums, atlētiem palielinās spēja koncentrēt uzmanību treniņu slodzēm un sacensību darbībai. Tomēr pašreizējā pētījumu procesa stadijā zinātnieki ir izdarījuši galveno secinājumu, ka pagaidām vislabāko ietekmi vibrācijas treniņi dod spēka un jaudas izpausmju jomās. Zinātniskajās publikācijās ir norādes, ka vislielāko efektivitāti uz neiromuskulāro sistēmu (lai optimizētu spēka un jaudas izpausmes) dod vibrācijas frekvences 30-50 Hz diapazonā. Šāda lieluma frekvences spēj dot tikai vibrācijas platformas, kurās nodrošina tikai visa ķermeņa vibrāciju, kuru uzskata par netiešas iedarbības vibrāciju. Tai ir mazāka efektivitāte nekā tiešajai vibrācijai vai lokālajai vibrācijai, kurā vibrācija tiek pielikta konkrētam muskulim vai tā cīpslai, un tam jau ir ievērojami lielāka efektivitāte. Tiešās vibrācijas vai lokālās vibrācijas gadījumā vibrācijas frekvence ir būtiski lielāka (>100 Hz), bet amplitūda ir mazāka (1-4 mm). Tātad, katra no šīm atšķirīgajām vibrācijas formām atšķirīgā veidā ietekmē muskuļus, un līdz ar to vibrācijai ir atšķirīga ietekme uz treniņu efektivitāti. Lai iegūtu lielāku efektu spēka un jaudas attīstībā, nepietiek tikai ar treniņos izmantoto vibrācijas slodžu intensitātes un apjoma palielināšanu vai ar vibrācijas frekvences un amplitūdas palielināšanu (Krauksts V., Ņemčenko A. 2011). Vispirms ir jānodrošina teicama vispārējā fiziskā sagatavotība un speciālā fiziskā sagatavotība, pēc tam treniņa procesā jāiekļauj vibrācija kā treniņa līdzeklis. Lai noteiktu katra sportista individuālo vibrācijas treniņa metodiku, vibrācijas pielikšanas laikā nepieciešams vērot un komunicēt ar sportistu. Lai gan vibrācijas treniņu metodika visiem sportistiem tiek izstrādāta vienāda, vibrācijas pielikšanas spēks ir dažāds.
