Purpose. The purpose of the study was to reveal a possible relationship between maximal gripping force and climbing ability as well as to compare a decrease in handgrip force caused by training session in male and female climbers. Basic procedures. Seventy-four climbers (49 males and 25 females) took part in a climbing session on artificial wall. Grip force of both hands was measured twice - before and after the training session. Main findings. The subjects self-reported their climbing abilities in a quantitative Australian scale. In both groups, climbing ability correlated with handgrip force related to body mass. Relative force significantly decreased (F1,72 = 53.2, p < 0.001) post-exercise from 6.83 ± 1.16 to 5.96 ± 1.18 N/kg in males and from 5.43 ± 0.91 to 4.94 ± 0.84 N/kg in females. The decrease was significantly greater in male climbers (F1,72 = 4.11, p < 0.05). Conclusions. Less decrease in strength postclimbing in female can positively affect their climbing ability and compensate lower relative handgrip strength. Women should draw more attention to maximal strength training while men to climbing technique and endurance.

Since rock climbing grows in popularity, the number of the respective scientific reports increases. However, those concerning anthropometric profile of elite climbers are scarce and inconsistent, thus the aim of the study was to describe the anthropometric characteristics of competitive sport climbers. Male rock climbers (n = 21) aged 17 - 29 years took part in the study; their climbing ability ranged from 6b to 8c in the French scale. Body height, body mass, arm span, length and girths of both extremities, shoulder and pelvis widths, as well as thickness of 5 skinfolds were determined. From these, body mass index (BMI), body fat content and selected anthropometric indices were calculated. Data collected for climbers were compared with those of untrained students (n = 165) of Warsaw Technical University. Although no between-group differences were found for body height, body mass, BMI or body fat content, the climbers exhibited significantly (p<0.001) lower pelvis-to-shoulder ratio, longer lower extremities (p<0.05), and greater arm length and arm span (p<0.001) compared to untrained students. The results of this study do not support the view that climbers are small in stature and of low body mass. It seems that the core of the issue is not in body size but rather in specific body proportions and this may be of great importance in selecting subjects to competitive sport climbing.

Background. The consequences of the COVID-19 pandemic include the emergence or intensification of negative emotional states, such as anxiety disorders or depression. The deterioration of the emotional state in human population can be explained by the severe increase in the level of psychological stress related to the pandemic. In turn, mental stress can lead to the appearance or exacerbation of psychosomatic symptoms. Mental stress is one of the risk factors for bruxism. Due to the current pandemic situation, there is an increase in the frequency of bruxism symptoms in the population. The aim of this study was to analyze the occurrence of bruxism symptoms in sports climbers during the COVID-19 pandemic. Material and methods. The study consisted of two stages - the first one was carried out in August 2019 and the second one was repeated in May 2020, three months after the national quarantine in Poland had been announced . 67 people in the control group and 67 in the studied group were qualified for the study. The occurrence of awake and sleep bruxism was determined using a questionnaire. Results. The collective analysis showed that the studied group had a lower percentage of respondents with awake bruxism compared to the control group - the results reached the required threshold of statistical significance. The prevalence of sleep bruxism between the groups was similar - the differences did not reach the assumed significance threshold. Conclusions. The level of bruxism symptoms among climbers was significantly lower during the COVID-19 pandemic than before it. The obtained results and possible adaptation mechanisms in climbers require further analysis.

Wstęp. Wśród następstw pandemii COVID-19 wyróżnia się m.in. pojawienie się bądź nasilenie negatywnych stanów emocjonalnych, takich jak zaburzenia lękowe czy depresja. Pogorszenie się stanu emocjonalnego populacji światowej można tłumaczyć gwałtownym wzrostem poziomu stresu psychologicznego związanego z pandemią. Z kolei napięcie psychiczne może prowadzić do pojawienia się lub zaostrzenia objawów psychosomatycznych. Stres psychiczny jest jednym z czynników ryzyka bruksizmu. W związku z obecną sytuacją pandemiczną obserwuje się wzrost częstotliwości występowania objawów bruksizmu w populacji. Celem niniejszego badania była analiza kształtowania się objawów bruksizmu u wspinaczy sportowych w czasie pandemii COVID-19. Materiał i metody. Badanie składało się z dwóch etapów – pierwszego,przeprowadzonego w sierpniu 2019 oraz drugiego, powtórzonego w maju 2020 roku, trzy miesiące od wprowadzenia w Polsce narodowej kwarantanny. Do badania zakwalifikowano 67 osób w grupie kontrolnej oraz 67 w grupie badanej. Określenie występowania bruksizmu dziennego i nocnego zostało wykonane za pomocą kwestionariusza ankiety. Wyniki. Analiza zbiorcza wykazała, że w grupie badanej występuje mniejszy procent respondentów z bruksizmem dziennym w stosunku do grupy kontrolnej - wyniki osiągnęły wymagany próg istotności statystycznej. Rozpowszechnienie bruksizmu nocnego między grupami było zbliżone – różnice nie osiągnęły założonego progu istotności. Wnioski. Poziom objawów bruksizmu wśród wspinaczy był istotnie niższy w trakcie pandemii COVID-19, niż przed nią. Otrzymane wyniki oraz możliwe mechanizmy adaptacyjne u wspinaczy wymagają dalszej analizy.
