Objectives: The aim of this study was to determine the effect of sacroiliac joint mobilization (SJM) in cases with sacroiliac joint dysfunction (SJD) on hamstring muscle flexibility and quadriceps muscle strength. Methods: Seven subjects age average (min- max) was 21.85 (21-23) years with SJD were included. Hamstring muscle flexibility was measured with passive knee extension (PKE) method by using goniometer; quadriceps muscle strength was measured by using a hand dynamometer. After osteopathic evaluation (sacroiliac joint stress and mobility tests) appropriate mobilization methods (ilium anterior, ilium posterior and sacrum R / R dysfunction mobilization) were performed in patients with sacroiliac joint dysfunction. All measurements were repeated before, immediately and 4 days after application. For statistical analysis, Friedman and Wilcoxon-Signed test was used. Results: Immediately after SIJ mobilization for 7 patients, hamstring muscle flexibility was evaluated and compared with pretreatment status; bilateral hamstring muscle flexibility improvement was observed (p <0.05). When the results at 4 days were compared with the pretreatment measurements, generated effect continued in the dominant side (p <0.05) and there were no changes observed in the non-dominant side (p> 0.05). When immediate and 4th-day measurements were compared, bilateral improvement was maintained(p> 0.05). When pretreatment and immediate posttreatment rsults were analysed, bilateral quadriceps muscle strength was found to be increased (p <0.05). When 4th- day and pretreatment measures were compared the effects were bilaterally maintained (p <0.05). Comparison of immediate postapplication and 4th-day measurements revealed that bilateral improvement continued (p> 0.05). Conclusion: In SJD patients known with hamstring muscle flexibility loss and quadriceps muscle weakness, private sacroiliac joint mobilization is effective in enhancing hamstring muscle flexibility and quadriceps muscle strength, so SJD could be considered for increasing quadriceps muscle strength and hamstring muscle flexibility.

This study aimed to systematically review research investigating the association between hip muscle strength and dynamic knee valgus (DKV). Four databases (MEDLINE, PubMed, CINAHL, and SPORTDiscus) were searched for journal articles published from inception to October 2020. Seven studies investigating the association between hip muscle strength and DKV using a two-dimensional motion analysis system in healthy adults were included. The relationship between hip abductor muscle strength and DKV was negatively correlated in two studies, positively correlated in two studies, and not correlated in three studies. The DKV was associated with reduced hip extensor muscle strength in two studies and reduced hip external rotator muscle strength in two studies, while no correlation was found in three and five studies for each muscle group, respectively. The relationship between hip muscle strength, including abductors, extensors, and external rotators and DKV is conflicting. Considering the current literature limitations and variable methodological approaches used among studies, the clinical relevance of such findings should be interpreted cautiously. Therefore, future studies are recommended to measure the eccentric strength of hip muscles, resembling muscular movement during landing. Furthermore, high-demand and sufficiently challenging functional tasks revealing lower limb kinematic differences, such as cutting and jumping tasks, are recommended for measuring the DKV.

Circulating Levels

ObjectiveIn aging populations, poor handgrip strength has been associated with physical disability and mortality. IGF1 is an important mediator of muscle growth and regeneration affecting muscle function. We studied the relationship between circulating levels of IGF1, its binding protein 3 (IGFBP3), and handgrip strength and physical performance in middle-aged- and oldest-old subjects.DesignCross-sectional analysis in two different cohorts composed of middle-aged- (n=672, mean 63.9±6.7 years) and oldest-old subjects (n=272, all 89 years).MethodsHandgrip strength, functional performance and ability, and serum levels of IGF1 and IGFBP3 were measured in all subjects and analyzed by linear regression for men and women separately.ResultsIGF1 and IGFBP3 levels declined with chronological age and were positively associated with handgrip strength in middle-aged- and oldest-old women (both, P<0.05), but not in men of either age group. Furthermore, higher serum levels of IGF1 were associated with slower walking speed in oldest-old men (P=0.012), and serum levels of IGFBP3 were positively associated with activities of daily living in the oldest-old women (P=0.002).ConclusionThe significant relationship between IGF1 levels and muscle strength found in women but not in men suggests a gender-specific influence of IGF1 on muscle strength. Further studies are necessary to test the relationship with physical performance.

The Relationship

2D:4D ratio is determined by balance between androgens and estrogens. Low level estrogen reduces bone mineral density (BMD) and incurs negative changes to bone microarchitecture, increasing the risk of osteoporosis and, as a consequence, fracture risk in women. The purpose of this study was to investigate the relationship between 2D:4D, muscle strength and body composition to BMD in young women. One hundred twenty-seven young women (age range 24-36 years) voluntarily participated in this study. Lengths of the second (index) and fourth (ring) fingers, upper and lower body strength and body composition (body mass index, BMI; waist to hip ratio, WHR) and body fat percentage were estimated. Also, blood levels of calcium and 25-hydroxyvitamin D (25OHD) were evaluated and dual-energy X-ray absorptiometry device was used to measure BMD in the lumbar spine (LS) and femoral neck (FN). The results showed that digit ratios, upper body and lower body muscle strength, BMI and fat percentage had a positive relationship with LS and FN BMD (LS BMD: r=.47, r=.56, r=.46, r=.34, r=.28, p≤.001, respectively; FN BMD: r=.34, r=.49, r=.51, r=.45, r=.27, p≤.001, respectively). In addition, there was no significant relationship between WHR and BMD of LS and FN (p˃.05). Multiple linear regression analysis showed the upper body strength was a stronger determinant of LS BMD and the lower body strength was a stronger determinant of FN BMD. Based on the results, the researchers concluded that upper and lower body strength, 2D:4D ratios and BMI were important determinants of young women’s BMD. Also, it seemed that some of these factors may be able to help predicting the osteoporosis potential in young women
