Research paper thumbnail of Effects of Blood Flow Restriction Training on Muscular Strength and Hypertrophy in Older Individuals: A Systematic Review and Meta-Analysis

Sports Medicine, 2018

Background The combination of low-load resistance training with blood flow restriction (BFR) has ... more Background The combination of low-load resistance training with blood flow restriction (BFR) has recently been shown to promote muscular adaptations in various populations. To date, however, evidence is sparse on how this training regimen influences muscle mass and strength in older adults. Purpose The purpose of this systematic review and meta-analysis was to quantitatively identify the effects of low-load BFR (LL-BFR) training on muscle mass and strength in older individuals in comparison with conventional resistance training programmes. Additionally, the effectiveness of walking with and without BFR was assessed. Methods A PRISMA-compliant systematic review and meta-analysis was conducted. The systematic literature research was performed in the following electronic databases from inception to 1 June 2018: PubMed, Web of Science, Scopus, CINAHL, SPORTDiscus and CENTRAL. Subsequently, a random-effects meta-analysis with inverse variance weighting was conducted. Results A total of 2658 articles were screened, and 11 studies with a total population of N = 238 were included in the metaanalysis. Our results revealed that during both low-load training and walking, the addition of BFR elicits significantly greater improvements in muscular strength with pooled effect sizes (ES) of 2.16 (95% CI 1.61 to 2.70) and 3.09 (95% CI 2.04 to 4.14), respectively. Muscle mass was also increased when comparing walking with and without BFR [ES 1.82 (95% CI 1.32 to 2.32)]. In comparison with high-load training, LL-BFR promotes similar muscle hypertrophy [ES 0.21 (95% CI − 0.14 to 0.56)] but lower strength gains [ES − 0.42 (95% CI − 0.70 to − 0.14)]. Conclusion This systematic review and meta-analysis reveals that LL-BFR and walking with BFR is an effective interventional approach to stimulate muscle hypertrophy and strength gains in older populations. As BFR literature is still scarce with regard to potential moderator variables (e.g. sex, cuff pressure or training volume/frequency), further research is needed for strengthening the evidence for an effective application of LL-BFR training in older people. Christoph Centner and Patrick Wiegel have contributed equally.

Materials and Methods A total of 31 female adolescent basketball athletes with a mean age of 12.3 years (SD: 0.9) were included. Isokinetic measurements were performed on quadriceps and hamstring muscles bilaterally using a dynamometer. Bilateral RF and FC thicknesses were evaluated by ultrasonography. For FC thickness, three mid-point measurements were taken bilaterally from each knee as follows: lateral condyle, intercondylar area, and medial condyle. Mean FC thickness for each knee was calculated by values pertaining to the medial and lateral condyles, and the intercondylar area. Results: Right and left mean FC thickness values were 0.23 (SD: 0.03) cm and 0.22 (SD: 0.03) cm. While there was a significant positive correlation between right and left FC thicknesses ...

Research paper thumbnail of The Association of Collagen 1A1, 5A1 and 12A1 Gene Expression with General Joint Laxity in Athletes is Non-Significant

The gene expression levels of type I, V, and XII collagens affect the components and properties of connective tissue. Therefore, in this study, we aimed to investigate the COL1A1, COL5A1, and COL12A1 gene expression levels, which have an effect on connective tissue properties and were previously associated with ligament injuries in athletes and assess their association with generalized joint laxity. Materials and Methods: 20 athletes were included in this study. Joint laxity was evaluated according to the Beighton Horan Joint Mobility Index (BHJMI). The participants were divided into two groups as non-hypermobile (n=11) and increased mobility and hypermobility (n=9) according to their BHJMI scores. The real-time polymerase chain reaction was used to determine the COL1A1, COL5A1, and COL12A1 gene expression levels. Results: There were no significant differences in the relative gene expressions of COL1A1, COL5A1, or COL12A1 between the groups. Conclusion: The gene expression levels of collagen types I, III, and V of participants with and without generalized joint laxity were not different. Genome-wide studies are recommended to evaluate the potential genetic variants associated with hypermobility, which causes sport-related injuries.

The aim of the research was to ask patients how they decided to make the injection, what treatments they received, their complaints prior to and after the injection and how they feel at the moment, and whether they are currently exercising or not. Thus, to demonstrate the patients' outcomes with their own expression. Materials and methods: A total of 92 knee OA patients completed semistructured interviews, which included six open-ended questions. Results: A total of 92 patients (66 female, 26 male) aged between 36 and 95 years (mean 65.5±11.1) were included. Before the injection, the majority of the OA patients had pain complaints when walking (72.8%) and 'ascending stairs (70.7%). One to four years after intraarticular injection, 45.2% of patients felt a decrease in their complaints. The majority of patients did not consider diet and exercise as a treatment option. In addition, almost all patients declared that they decided on hyaluronic acid injection treatment with the physician's recommendation. Conclusion: Pain during walking and ascending stairs before hyaluronic acid injection was common in knee-OA patients. Overall the patients felt a decrease in the symptoms after injection. Patients did not consider diet and exercise as a treatment option despite the recommendation by a physician.

Although they are most frequently observed in children and adolescents, they are encountered in adults as well. Currently, they are classified according to the Meyers and McKeever classification modified by Zaricznyj. Various surgical techniques have been described. The current management has changed from open reduction and internal fixation to arthroscopic reduction and internal fixation. Arthroscopic management for reduction and fixation of these fractures is currently accepted as the gold standard technique for displaced fractures. Although fracture pattern, patient characteristics, and the surgeon’s experience influence the management, anatomical fracture reduction and rigid internal fixation is of greatest importance for displaced tibial eminentia fractures. Residual anterior joint laxity is the most common complication. However, healing is successful for most fractures, and residual laxity does not relate strongly with subjectively successful clinical outcomes. This chapter provides a detailed description of the “transquadricipital tendinous portal” arthroscopic approach for tibial eminentia fracture fixation.

As a weight-bearing joint, the knee is prone to injury both during daily activities and in sports. Injuries to the knee are especially prevalent in contact sports, such as soccer, basketball, volleyball, hockey, and American football. According to National Collegiate Athletic Association (NCAA) statistics from 1988–1989 to 2003–2004, more than 50% of all injuries involved the lower extremity (Hootman et al. 2007). In an epidemiological study of elite male football players from 2001 to 2013, 45% of traumatic fractures and 86% of stress fractures affected the lower extremity (Larsson et al. 2016). In a Union of European Football Associations (UEFA) study, the incidence of knee injuries among professional football players between 2001 and 2008 was reported to be 18% (Ekstrand et al. 2011). The knee was also the most frequent site of lower body injury (33%) during th...

Plantar pressure and foot loading patterns may change with joint hypermobility. We aimed to analyze static plantar pressure in young females with and without joint hypermobility.MethodsJoint laxity in 27 young females was assessed cross sectionally using the Beighton and Horan Joint Mobility Index. Participants were divided into the hypermobility (score, 4–9) and no hypermobility (score, 0–3) groups according to their scores. Static plantar pressure and forces were recorded using a pedobarographic mat system.ResultsHigher peak pressures (P = .01) and peak pressure gradients (P = .025) were observed in the nondominant foot in the hypermobility group. According to the comparison of dominant and nondominant feet in each group, the hypermobility group showed significantly higher peak pressures (P = .046), peak pressure gradients (P = .041), and total force values (P = .028) in the nondomi...

Therefore, the aims of this study were to evaluate FC thickness via ultrasound among elite athletes involved in different types of HIPA, and to determine whether there is a correlation between serum cartilage oligomeric matrix protein (sCOMP) and rectus femoris (RF) thickness. Method A total of 132 male individuals participated in this study and were assigned to two groups, the sedentary (n = 43, 23.9 ± 3.7) and athlete groups (n = 89, 22.7 ± 4.6), which did not significantly differ in age. The athletes were elite and performed HIPA during sports such as volleyball (n = 20), soccer (n = 21), basketball (n = 28), and weightlifting (n = 20). RF thickness and three (mid-point) measurements were obtained for each knee. The mean FC thickness for each knee was defined as the sum of the medial, lateral condyles, and intercondylar areas. Blood samples for sCOMP analyses were also obtained. Results All the measurements of the FC of both knees were significantly higher in the athletes than in the sedentary individuals (p < 0.001 and p = 0.001). The mean right and left FC values were also higher in the athletes (p < 0.001). Multiple linear regression analysis showed that participation in sporting activities was a significant predictor associated with the right and left mean FC thickness (p < 0.001 for both). No significant differences in the sCOMP levels were found between the two groups. Conclusion It was found that the mean FC was higher among athletes than among sedentary individuals. As a result, it is suggested that sports' participation is an independent factor associated with the right and left mean FC thickness. Level of evidence III.

However, the number of participants to such events, age and sex distribution of participants may vary by country. Material and methods: We have investigated participation trends and performances of the finishers of three different courses (15km, half-marathon, marathon) in two of the biggest running events in Turkey (the Antalya and Istanbul marathons) between 2007-2017. Results: Our results have shown that runners who completed the 15km course were the highest and marathon finishers were the lowest in number each year. Among native runners, male participation in each distance and event is higher than female participation. Native female marathon finishers increased only by 0.23% in 6 years. In all distances, women run at a lower average speed than men each year. Between 2007-2017, the mean average speed of women were 9.10km/h (±0.18), 9.71km/h (±1.62) and 9.72km/h (±1.73) and the mean average speed of men were 10.45km/h (±2.02), 10.89km/h (±1.83) and 10.40km/h (±1.80) at 15km, 21km and 42km respectively. Conclusions: An important sex gap was observed in participation in long-distance runs in Turkey, which is more pronounced in marathons. Performance analysis showed that females' mean average speed is lower than males' in all distances.

This study aimed to determine the mean TBS values in healthy postmenopausal women and overall association between TBS and demographic features, bone mineral density (BMD) of the lumbar spine and femoral neck, and BMD to body mass index (BMI) ratio of the lumbar spine. Methods: Fifty-three postmenopausal healthy women were enrolled. The BMD of the lumbar spine and femoral neck was measured by DXA. Anteroposterior lumbar spine acquisitions were used to calculate the TBS for L1 to L4. Results: The mean BMD of the lumbar spine and femoral neck was 0.945 AE 0.133 and 0.785 AE 0.112 g/cm 2 , respectively. The mean TBS was 1.354 AE 0.107. There was a significant positive moderate correlation between TBS and total lumbar BMD to BMI ratio (r ¼ 0.595, P < 0.001), and significant positive weak correlations between TBS and BMD of the lumbar spine (r ¼ 0.347, P ¼ 0.011) as well as between TBS and femoral neck (r ¼ 0.305, P ¼ 0.026), whereas significant negative moderate correlations were observed between TBS and age (r ¼ À0.393, P ¼ 0.004) as well as between TBS and BMI (r ¼ À0.333, P ¼ 0.015). Conclusions: TBS values of postmenopausal women were negatively correlated with age and BMI, and positively with BMD and BMD to BMI ratio.

The aim of this study is to determine serum levels of these molecules in runners after a long-distance trail run. Serum IL-15 levels after such endurance events have not been investigated yet. Blood samples were collected from 37 athletes (11 female, 26 male) before and after a 35-km trail run, with a total climb of 940 m. Serum was obtained from the samples, and IL-6, IL-15, and Hsp72 levels were measured from using the sandwich ELISA method. The athletes completed the race in 308.3 ± 37.4 min on average. After the race, the mean serum IL-6, IL-15, and Hsp72 concentrations increased 13.2-fold, 2.22-fold, and 1.6-fold, respectively (p < 0.001, p < 0.001, and p = 0.039, respectively). This is the first study to demonstrate the increase in serum IL-15 levels following an acute endurance exercise. In addit...

To date, however, evidence is sparse on how this training regimen influences muscle mass and strength in older adults. Purpose The purpose of this systematic review and meta-analysis was to quantitatively identify the effects of low-load BFR (LL-BFR) training on muscle mass and strength in older individuals in comparison with conventional resistance training programmes. Additionally, the effectiveness of walking with and without BFR was assessed. Methods A PRISMA-compliant systematic review and meta-analysis was conducted. The systematic literature research was performed in the following electronic databases from inception to 1 June 2018: PubMed, Web of Science, Scopus, CINAHL, SPORTDiscus and CENTRAL. Subsequently, a random-effects meta-analysis with inverse variance weighting was conducted. Results A total of 2658 articles were screened, and 11 studies with a total population of N = 238 were included in the metaanalysis. Our results revealed that during both low-load training and walking, the addition of BFR elicits significantly greater improvements in muscular strength with pooled effect sizes (ES) of 2.16 (95% CI 1.61 to 2.70) and 3.09 (95% CI 2.04 to 4.14), respectively. Muscle mass was also increased when comparing walking with and without BFR [ES 1.82 (95% CI 1.32 to 2.32)]. In comparison with high-load training, LL-BFR promotes similar muscle hypertrophy [ES 0.21 (95% CI − 0.14 to 0.56)] but lower strength gains [ES − 0.42 (95% CI − 0.70 to − 0.14)]. Conclusion This systematic review and meta-analysis reveals that LL-BFR and walking with BFR is an effective interventional approach to stimulate muscle hypertrophy and strength gains in older populations. As BFR literature is still scarce with regard to potential moderator variables (e.g. sex, cuff pressure or training volume/frequency), further research is needed for strengthening the evidence for an effective application of LL-BFR training in older people. Christoph Centner and Patrick Wiegel have contributed equally.

The gene expression levels of type I, V, and XII collagens affect the components and properties of connective tissue. Therefore, in this study, we aimed to investigate the COL1A1, COL5A1, and COL12A1 gene expression levels, which have an effect on connective tissue properties and were previously associated with ligament injuries in athletes and assess their association with generalized joint laxity. Materials and Methods: 20 athletes were included in this study. Joint laxity was evaluated according to the Beighton Horan Joint Mobility Index (BHJMI). The participants were divided into two groups as non-hypermobile (n=11) and increased mobility and hypermobility (n=9) according to their BHJMI scores. The real-time polymerase chain reaction was used to determine the COL1A1, COL5A1, and COL12A1 gene expression levels. Results: There were no significant differences in the relative gene expressions of COL1A1, COL5A1, or COL12A1 between the groups. Conclusion: The gene expression levels of collagen types I, III, and V of participants with and without generalized joint laxity were not different. Genome-wide studies are recommended to evaluate the potential genetic variants associated with hypermobility, which causes sport-related injuries.

The aim of the research was to ask patients how they decided to make the injection, what treatments they received, their complaints prior to and after the injection and how they feel at the moment, and whether they are currently exercising or not. Thus, to demonstrate the patients' outcomes with their own expression. Materials and methods: A total of 92 knee OA patients completed semistructured interviews, which included six open-ended questions. Results: A total of 92 patients (66 female, 26 male) aged between 36 and 95 years (mean 65.5±11.1) were included. Before the injection, the majority of the OA patients had pain complaints when walking (72.8%) and 'ascending stairs (70.7%). One to four years after intraarticular injection, 45.2% of patients felt a decrease in their complaints. The majority of patients did not consider diet and exercise as a treatment option. In addition, almost all patients declared that they decided on hyaluronic acid injection treatment with the physician's recommendation. Conclusion: Pain during walking and ascending stairs before hyaluronic acid injection was common in knee-OA patients. Overall the patients felt a decrease in the symptoms after injection. Patients did not consider diet and exercise as a treatment option despite the recommendation by a physician.

Although they are most frequently observed in children and adolescents, they are encountered in adults as well. Currently, they are classified according to the Meyers and McKeever classification modified by Zaricznyj. Various surgical techniques have been described. The current management has changed from open reduction and internal fixation to arthroscopic reduction and internal fixation. Arthroscopic management for reduction and fixation of these fractures is currently accepted as the gold standard technique for displaced fractures. Although fracture pattern, patient characteristics, and the surgeon’s experience influence the management, anatomical fracture reduction and rigid internal fixation is of greatest importance for displaced tibial eminentia fractures. Residual anterior joint laxity is the most common complication. However, healing is successful for most fractures, and residual laxity does not relate strongly with subjectively successful clinical outcomes. This chapter provides a detailed description of the “transquadricipital tendinous portal” arthroscopic approach for tibial eminentia fracture fixation.

Therefore, the aims of this study were to evaluate FC thickness via ultrasound among elite athletes involved in different types of HIPA, and to determine whether there is a correlation between serum cartilage oligomeric matrix protein (sCOMP) and rectus femoris (RF) thickness. Method A total of 132 male individuals participated in this study and were assigned to two groups, the sedentary (n = 43, 23.9 ± 3.7) and athlete groups (n = 89, 22.7 ± 4.6), which did not significantly differ in age. The athletes were elite and performed HIPA during sports such as volleyball (n = 20), soccer (n = 21), basketball (n = 28), and weightlifting (n = 20). RF thickness and three (mid-point) measurements were obtained for each knee. The mean FC thickness for each knee was defined as the sum of the medial, lateral condyles, and intercondylar areas. Blood samples for sCOMP analyses were also obtained. Results All the measurements of the FC of both knees were significantly higher in the athletes than in the sedentary individuals (p < 0.001 and p = 0.001). The mean right and left FC values were also higher in the athletes (p < 0.001). Multiple linear regression analysis showed that participation in sporting activities was a significant predictor associated with the right and left mean FC thickness (p < 0.001 for both). No significant differences in the sCOMP levels were found between the two groups. Conclusion It was found that the mean FC was higher among athletes than among sedentary individuals. As a result, it is suggested that sports' participation is an independent factor associated with the right and left mean FC thickness. Level of evidence III.

However, the number of participants to such events, age and sex distribution of participants may vary by country. Material and methods: We have investigated participation trends and performances of the finishers of three different courses (15km, half-marathon, marathon) in two of the biggest running events in Turkey (the Antalya and Istanbul marathons) between 2007-2017. Results: Our results have shown that runners who completed the 15km course were the highest and marathon finishers were the lowest in number each year. Among native runners, male participation in each distance and event is higher than female participation. Native female marathon finishers increased only by 0.23% in 6 years. In all distances, women run at a lower average speed than men each year. Between 2007-2017, the mean average speed of women were 9.10km/h (±0.18), 9.71km/h (±1.62) and 9.72km/h (±1.73) and the mean average speed of men were 10.45km/h (±2.02), 10.89km/h (±1.83) and 10.40km/h (±1.80) at 15km, 21km and 42km respectively. Conclusions: An important sex gap was observed in participation in long-distance runs in Turkey, which is more pronounced in marathons. Performance analysis showed that females' mean average speed is lower than males' in all distances.

Research paper thumbnail of Trabecular bone score of postmenopausal women is positively correlated with bone mineral density and negatively correlated with age and body mass index

This study aimed to determine the mean TBS values in healthy postmenopausal women and overall association between TBS and demographic features, bone mineral density (BMD) of the lumbar spine and femoral neck, and BMD to body mass index (BMI) ratio of the lumbar spine. Methods: Fifty-three postmenopausal healthy women were enrolled. The BMD of the lumbar spine and femoral neck was measured by DXA. Anteroposterior lumbar spine acquisitions were used to calculate the TBS for L1 to L4. Results: The mean BMD of the lumbar spine and femoral neck was 0.945 AE 0.133 and 0.785 AE 0.112 g/cm 2 , respectively. The mean TBS was 1.354 AE 0.107. There was a significant positive moderate correlation between TBS and total lumbar BMD to BMI ratio (r ¼ 0.595, P < 0.001), and significant positive weak correlations between TBS and BMD of the lumbar spine (r ¼ 0.347, P ¼ 0.011) as well as between TBS and femoral neck (r ¼ 0.305, P ¼ 0.026), whereas significant negative moderate correlations were observed between TBS and age (r ¼ À0.393, P ¼ 0.004) as well as between TBS and BMI (r ¼ À0.333, P ¼ 0.015). Conclusions: TBS values of postmenopausal women were negatively correlated with age and BMI, and positively with BMD and BMD to BMI ratio.

Research paper thumbnail of Acute long-distance trail running increases serum IL-6, IL-15, and Hsp72 levels

The aim of this study is to determine serum levels of these molecules in runners after a long-distance trail run. Serum IL-15 levels after such endurance events have not been investigated yet. Blood samples were collected from 37 athletes (11 female, 26 male) before and after a 35-km trail run, with a total climb of 940 m. Serum was obtained from the samples, and IL-6, IL-15, and Hsp72 levels were measured from using the sandwich ELISA method. The athletes completed the race in 308.3 ± 37.4 min on average. After the race, the mean serum IL-6, IL-15, and Hsp72 concentrations increased 13.2-fold, 2.22-fold, and 1.6-fold, respectively (p < 0.001, p < 0.001, and p = 0.039, respectively). This is the first study to demonstrate the increase in serum IL-15 levels following an acute endurance exercise. In addit...
