Study aim: To assess the handgrip strength in Indian university softball players as dependent on selected hand-anthropometric variables.Material and methods: Indian university softball players (121 males and 122 females) and untrained controls (98 males and 102 females) aged 18 - 25 years participated in the study. The following variables were recorded: body height and mass, BMI, right hand width and length, lengths of the right 2nd, 3rd and 4th digits and right handgrip strength.Results: One-way ANOVA showed significant differences (p<0.05 - 0.001) in all the characteristics studied, except body height, right hand length and right 2nd digit length among these four sets of data. The right handgrip strength was significantly correlated (p<0.01 - 0.001) with all the variables studied. Both in male and female softball players, the partition of R2 into the contributions of individual independent variables revealed that body height (18%), hand width (11%), body mass (8%) and hand length (5%) significantly contributed to the total variance (44%) of handgrip strength.Conclusions: The data might be useful in selecting players and in talent identification for softball.

Introduction: Damage to flexor tendons constitutes the prevailing area of traumatic injuries to a hand. Without appropriate, instantaneous postoperative rehabilitation various secondary changes like adhesions to surrounding tissues occur and it makes complete restitution of skills in the hand impossible. Generally, traumatic tendons of flexors injuries are treated primarily. However, some patients for various reasons require repeated surgery procedures, for example: two-stage flexor tendon reconstruction.Aim of the study: To compare rehabilitation results in patients after two-stage flexor tendon reconstruction with the results of individuals following one-stage surgical treatment of injured flexor tendons in the second area.Material and methods: The research group was composed of 17 patients after second stage flexor tendon reconstruction from the second to the fifth finger, for whom there primarily appeared a tendon injury in the second area. The control group consisted of 17 persons, who had had surgical fusion of the corresponding tendons performed. Routine physiotherapeutic diagnostics constituted the method of examination, composed of details, as follows: range of movement measurements, dynamometric measurements, examination of sensory and manipulative skills. Functioning of hand assessment was based on Swanson’s methodology. All patients underwent an individual program of rehabilitation which was based on physiotherapeutic, kinesitherapeutic and apparating procedures individually matched for each patient. The program was completed by exercises performing by the patients at home.Results: Both in the research group and control group, significant improvement of hand functioning between the first and the last examination was noticed. However, when compared to the research group, the hand functioning defect in both examinations was lesser in the control group. The rehabilitation duration of patients from the research group was significantly longer than in the control group. Conclusion: Rehabilitation after two-stage flexor tendon reconstruction leads to a significant improvement of hand functioning, however the treatment duration is longer.
