Functional assessment of women practising combat sports and team sports using the Functional Movement Screen

Relationship between the number of steps taken during lockdown caused by the COVID-19 pandemic and low back pain

Introduction: In 2020, the whole world was overwhelmed by the SARS-CoV-2 coronavirus threat. In order to prevent the spread of the virus, national governments introduced restrictions of movement in public space, closing schools, universities, many companies switched to remote working. In addition to the obvious benefits of the above changes, numerous side effects can be observed. One of them is pain in the locomotive organs caused by the sedentary lifestyle. Objective: The main objective of the study was to assess the relationship between physical activity during quarantine, caused by the COVID-19 pandemic, and the occurrence of spinal pain. Material and methods: The study was attended by 55 people (29 women and 26 men) who attended physiotherapeutic consultations due to low back pain. For comparison purposes, they were divided into two groups: Group 1 (n=24) includes active persons, Group 2 (n=31) includes inactive persons. The survey was conducted in June 2020. The study used the reading of pedometers from mobile phones and the Rolland-Morris Questionnaire, Laitinen’s Pain Scale and author’s own questionnaire. The respondents were asked to share the pedometer results from given weeks before, during and after restriction causes by the COVID-19. Results: Physically active persons (those performing health training) performed more steps before introducing restrictions (p<0.001). After the introduction of restrictions, all-day activity decreased significantly in both groups. The evaluation of pain characteristics revealed significant differences (between groups) in two categories – pain intensity and physical activity limitation. Group 2 individuals also reported greater functional limitations. Conclusion: In physically inactive people, the intensity of low back pain was much higher. This proves the relationship between activity levels and pain.

The Second-to-Fourth Digit (2D:4D) Ratio of Male Combat Athletes is Associated with the Choice of Sport

The second-to-fourth-digit (2D:4D) ratio has been widely used as a putative marker of prenatal exposure to testosterone in health, behavioral and sport sciences, but it has only been used few times regarding combat athletes. This study involved 200 male elite combat athletes (Olympic wrestling, kickboxing, judo, taekwondo and karate) and 179 males not participating in any sports. The lengths of the index finger (2D) and ring (4D) finger were measured using computer-assisted image analysis (AutoMetric 2.2 software). The 2D:4D ratio of combat athletes was significantly lower than that of the controls. Moreover, a lower 2D:4D ratio was found among wrestlers, judo athletes and kickboxers than in the control group, and a higher 2D:4D ratio was found, but with borderline significance, among karate and taekwondo athletes. Moreover, multivariate analysis adjusted for age showed that judo, Olympic wrestling and kickboxing athletes combined had 2D:4D ratios significantly lower (by 0.035 on average) than those of the rest of the subjects and that karate and taekwondo athletes together had 2D:4D ratios significantly higher (by 0.014 on average) than those of the rest of the subjects. The research results and literature review indicate that knowledge about the functional meaning of the 2D:4D ratio is still too fragmentary and it is too early to use the 2D:4D ratio in the selection of sport talent; however, it may be a useful criteria when screening prospective athletes to be recruited to a team. That is why 2D:4D reference values should be defined for particular sports.

Classic sports massage vs. Chinese self-massage. Which one is more effective in warm-up?

Study aim: Warm-up is an indispensable element of sports training. The aim of the study was to determine the effect of warm-up exercises with Swedish, classic sports massage and Chinese self-massage on functional limitations of the locomotive system.

Materials and methods: The study included 42 women and 13 men aged 19 to 22. They all performed the Functional Movement Screen (FMS) test, without a warm-up, and then (after a week) performed it again after either a standard warm-up with sports massage (Group 1) or a warm-up with Chinese self-massage (Group 2).

Results: Both groups obtained significantly higher results in the second measurement (FMS test), preceded by a standard warm-up with sports massage (Group 1, p = 0.003) and warm-up with Chinese self-massage (Group 2, p = 0.000). In Group 1, statistically significant differences were observed in the results of the exercises: hurdle step and push-ups. In Group 2, the difference was significant in the attempts to sit down deep, walk over the fence and pump.

Conclusion: There were no significant differences between the groups that used massage and self-massage. Both methods can improve movement functionality.
