The Relationship

The rate of force development (RFD) is vital for power athletes. Lean body mass (LBM) is considered to be an essential contributor to RFD, nevertheless high RFD may be achieved by athletes with either high or low LBM. The aim of the study was to describe the relationship between lower-body LBM and RFD, and to compare RFD in taekwondo athletes and track and field (T&F) throwers, the latter having higher LBM when compared to taekwondo athletes. Nine taekwondo athletes and nine T&F throwers were evaluated for countermovement jumping, isometric leg press and leg extension RFD, vastus lateralis (VL), and medial gastrocnemius muscle architecture and body composition. Lower body LBM was correlated with RFD 0–250 ms (r = 0.81, p = 0.016). Taekwondo athletes had lower LBM and jumping power per LBM. RFD was similar between groups at 30–50 ms, but higher for throwers at 80–250 ms. RFD adjusted for VL thickness was higher in taekwondo athletes at 30 ms, but higher in throwers at 200–250 ms. These results suggest that lower body LBM is correlated with RFD in power trained athletes. RFD adjusted for VL thickness might be more relevant to evaluate in power athletes with low LBM, while late RFD might be more relevant to evaluate in athletes with higher LBM.

The Relationship

Context:Subacromial impingement is a common injury in baseball players and has been linked to a reduction in the subacromial space. In addition, it has been suggested that decreases in scapular upward rotation will lead to decreases in the subacromial space and ultimately impingement syndrome.Objective:The objective of this study was to evaluate the relationship between acromiohumeral distance and scapular upward rotation in healthy college baseball players.Design:Posttest-only study design.Setting:Controlled laboratory setting.Participants:24 healthy college baseball players.Intervention:Participants were measured for all dependent variables at preseason.Main Outcome Measures:Acromiohumeral distance at rest and 90° of abduction was measured with a diagnostic ultrasound unit. Scapular upward rotation at rest and 90° of abduction was measured with a digital inclinometer.Results:Dominant-arm acromiohumeral distance at rest and 90° of abduction (P = .694, P = .840) was not significantly different than in the nondominant arm. In addition, there was not a significant correlation between acromiohumeral distance and scapular upward rotation at rest and 90° of abduction for either the dominant or the nondominant arm.Conclusions:These results indicate that the acromiohumeral distance is not adapting in the dominant arm in healthy throwing athletes. In addition, a relationship was not identified between acromiohumeral distance and scapular upward rotation, which was previously suggested. These results may suggest that changes that are typically seen in an injured population may be occurring due to the injury and are not preexisting. In addition, scapular upward rotation may not be the only contributing factor to acromiohumeral distance.

Abstract Background and Aims Studies have suggested that higher lean body mass (LBM) is associated with increased longevity among haemodialysis (HD) patients. It has been shown that creatinine index is a surrogate marker of lean body mass and can be estimated using a simplified equation based on age, gender, serum creatinine and KT/V(sp). The present study was conducted to investigate the association between estimated creatinine index and all-cause mortality in a large racially diverse cohort of incident HD patients. We also examined the relationship between creatinine index and hospitalisation incidence in this cohort. Method Incident patients (aged≥18 years) between January, 2010 and December, 2018 who survived six months of HD were included in this retrospective observational study. Baseline demographic data was collected at study commencement, followed by clinical and laboratory data during the 6 month exposure period. Patients were followed from the index date (last day of exposure period) until first of the following – death, withdrawal or end of study (June 30, 2019). The exposure of interest was Creatinine Index (CI) estimated using a simplified formula (Canaud et al 2014) based on patient demographics (age and gender), pre-dialysis serum creatinine and KT/V(sp). Patients were stratified into 4 groups based on CI quartiles - Q1(<=17.48), Q2(17.49-18.91), Q3(18.92-20.54) and Q4(20.55+). Primary outcome was all-cause mortality during the overall follow-up. Adjusted hazard ratios were estimated using a Cox regression model for association between CI quartiles and mortality. Negative binomial regression models were used to assess the relationship between CI quartiles and hospitalisation. Results A total of 3172 incident HD patients (mean age 60.4±11.5 years, 56.2% male, 57.4% Chinese and 70.4% with diabetes as cause of ESRD) were included in the study. During the median follow-up of 2.8 (1.4-4.7) years, 755 (23.8%) patients died. The mean creatinine index for entire cohort was 19.1±2.3 mg/kg/day. The patients in the lowest CI quartile (Q1) were older, females, had higher incidence of diabetes and comorbidity but lower levels of albumin, haemoglobin, BMI and SGA scores compared to higher quartiles (p<0.001). Following multivariate analysis the adjusted hazard of death were as follows - Q4 (aHR-1, reference), Q1 (aHR-2.14, 95%CI 1.56-2.94), Q2 (aHR-1.58, 95%CI 1.21-2.05), Q3 (aHR-1.33, 95%CI 1.05-1.68), p<0.001. Patients in the lowest quartile of CI (Q1) had 64% higher incidence of hospitalisation (IRR 1.64, 95%CI 1.36–1.98, p<0.001) compared with patients in Q4 (IRR-1, reference). Conclusion Creatinine index derived from a simplified equation is useful in predicting mortality and hospitalisation among Southeast Asian incident HD patients. Low CI was associated with increased risk of all-cause mortality and hospitalisation in our cohort. The present study is limited by the lack of data on residual renal function which might confound the results.
