Gibkość kręgosłupa w ostatnich latach jest uważana za istotny element sprawności fizycznej. Bouchard i Shephard (1994) wskazują gibkość jako jeden z komponentów i czynników sprawności, który w sposób szczególny warunkuje zdrowie i niezależność jednostki. Badaniami objętych zostało 50 kobiet w wieku 60 - 69 lat. Uczestniczki projektu badawczego podzielone zostały na pięć grup: cztery grupy badawcze, które uczestniczyły w eksperymencie pedagogicznym oraz jedną grupę kontrolną. Grupy badawcze (eksperymentalne) realizowały różne programy treningowe. Na podstawie szczegółowych analiz ustalono, że wszystkie programy treningowe przyczyniły się do poprawy gibkości kręgosłupa u przynajmniej 50% badanych osób w każdej z grup treningowych. Nie zauważono znaczących różnic w rezultatach uzyskanych w poszczególnych grupach treningowych zarówno pod względem praktycznym jak i statystycznym. Każdy program treningowy miał więc podobny wpływ na zmianę wyniku.

In recent years, flexibility of the spine has been considered an important element of physical fitness. Bouchard and Shephard (1994) point out flexibility as one of the elements and factors which particularly condition for health and independence of a person. Fifty women were enrolled in the study, aged 60-69 years. The subjects were split into 5 groups: 4 study groups which took part in a pedagogical experiment and 1 control group. The study groups (experimental) accomplished different training programs. Based on detailed analyses, it was observed that all the training programs, caused improvement in flexibility of the spine in at least 50% of subjects in each training group. No significant differences in the obtained results were observed among the groups, neither in practical, nor in statistical terms. That is, each training program had similar impact on the changes in performance.

Background: The aim of this preliminary study was to characterize handgrip strength indexes in elderly women with low bone mass and determine their relationship with age. Material/Methods: The study sample consisted of 63 postmenopausal women with osteopenia and ostoporosis, aged 60-74. The subjects were divided into three age groups: 60-64 years, 65-69 years and 70-74 years. To perform this study two handgrip strength indexes were used: handgrip strength on body weight (HS/weight) and handgrip strength on body mass index (HS/BMI). Handgrip strength was measured with Jamar hand dynamometer. Results: These studies revealed a significant decrease in handgrip strength indexes between age groups: 60-64 years and 70-74 years. As for the average HS/weight, it was registered: 0.38 ±0.07 kg for the group 60-64 years, 0.33 ±0.06 kg for the group 65-69 years and 0.32 ±0.05 kg for group 70-44 years. The results of the average HS/BMI in three groups were as follows: 0.99 ±0.24 kg/kg/m2, 0.86 ±0.19 kg/kg/m2 and 0.8 ±0.16 kg/kg/m2, respectively. Conclusions: Handgrip strength indexes in elderly women with low bone mass are gradually decreasing with age. Thus, handgrip strength indexes could provide a convenient tool for clinicians to set goals and to monitor the training progress in women with osteopenia and osteoporosis.

Background: One of the effects of involution is the change in the body posture. Muscles lose their flexibility and strength, causing the typical changes in body posture of the elderly. Hyperkyphosis is a typical feature of the posture, which leads to serious health problems. The aim of the study was to analyse changes in the body posture of elderly women who took part in diversified Nordic walking training. Material and methods: ‪The study group comprised 90 elderly women divided into two experimental groups and control. The main method was an experiment. The tested women took part in a 6-month Nordic walking training cycle. Women from the control group did not take part in any organised form of physical activity. Evaluation of the body posture was made by the silhouette-based Staffel method. Results: ‪Nordic walking training has led to certain changes in the body posture. Women from experimental groups have improved their body posture. In the control some significant negative changes have been observed. Conclusions: ‪Nordic walking is extremely useful for modelling body posture of the elderly. When the programme is complemented with the strengthening and stretching exercises, which shape the postural muscles, the effects are intensified.
