“…It is known that SLJ not only measures lower body explosive muscular strength but is also highly associated with upper body muscular strength [42]. The test has been suggested as a general index of muscular fitness [42] and positive determinant of bone mineral density in young people [43]. The reason for the significant association between the cognitive tasks and explosive strength (but not static strength) in the youths seen in our study is not clear.…”

The present study aimed to explore the association between physical fitness (PF) and cognitive performance in a sample of 19-24 year old males. Two hundred and eleven young males (20.2±1.5 years) participated in the study. Cognitive functioning tasks including information processing speed and inhibitory control were measured in addition to PF and motor fitness components such as aerobic fitness, static strength, explosive strength, agility and speed. Regression analysis showed that after adjustment for potential confounders (e.g. age, socioeconomic status, adiposity and physical activity), aerobic fitness (represented by shorter time in the one-mile run) was positively associated with composite inhibitory control scores (standardized β=0.17; p=0.04) and negatively associated with ∆ Simon (standardized β= -0.21; p=0.04). Explosive strength was negatively associated with composite information processing scores (standardized β= -0.24; P=0.01), and composite inhibitory control scores (standardized β= -0.22; p=0.02). Speed of movement, agility and static strength were not associated with any of the cognitive tests. In conclusion, aerobic fitness and explosive strength but not speed, agility or static strength might be indicators of underlying cognitive functioning tasks in 19-24 year old males.

“…Said same research also found that poorer subjects had lower lean mass unlike their counterparts (p <0.05) (60). El Hage et al, found that the hip BMD (Bone Mineral Density) was correlated positively with the performance of the vertical jump (r = 0.78, p <0.01) and longitudinal jump (r = 0.67, p <0.05) (61). Although many hypotheses exist regarding the results obtained, further research is needed to interpret the association between rural origin and MTSS.…”

Medial Tibial Stress Syndrome (MTSS) is one of the most-often reported and incapacitating pathologies in military personnel. Given that the muscles of the lower limb conduct an important task in attenuating impact forces when running and landing, deficiency and asymmetries in the neuromuscular function are associated with greater risk of having musculoskeletal injuries (MSI). Objective: the work sought to determine the risk factors for MTSS associated with the kinetics of the countermovement jump (CMJ) in cadets undergoing training. Methodology: a cohort of 164 cadets was monitored prospectively during 24 weeks. Upon starting the research, the study recorded the anthropometric and demographic data of the participants and inquired on some of their life habits and antecedents in using orthopedic material, injuries in lower limbs, and MTSS. Jump height (cm), eccentric deceleration of rate force development (EDRFD

No relationships reported)Dipeptidyl-Peptidase IV (DPP-IV) is an enzyme present in the blood, acting as a regulator for incretin hormones, such as glucagon-like peptide(GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). As a result of this regulatory action, DPP-IV has become an enzyme of interest in the pathology of Type 2 Diabetes. Currently, values are measured primarily in the plasma using a fluorometric assay; however, the stability of DPP-IV activity during storage over several weeks is of question. PURPOSE: To determine the stability of plasma DPP-IV activity following freezer storage. METHODS: Plasma samples were collected from 7 healthy college aged students. Blood was collected using standard venipuncture from a prominent antecubital vein. Plasma was separated by centrifugation for 10 minutes at 1,000g and 4°C. It was then removed and stored in 0.5mL aliquots at -80°C until analysis. DPP-IV activity was determined using fluorometric assay which measures the release of 4-methoxy-2naphthylamine (Scharpe et al. 1988). All solutions and buffers were prepared the same day. One unit (U) of enzymatic activity is defined as the amount of DPP-IV that cleaves 1µmol of glycyl-L-proline-4-methoxy-2nephthylamine per minute. The assay was repeated again one and two weeks after the first trial. A one-way repeated measure ANOVA was used to test for differences among time points (α=0.05). A coefficient of variation was calculated for each participant and averaged for a total coefficient of variation. RESULTS: Mean DPP-IV activity for Day 1 was 34.57 ± 6.80U/L. One week later, DPP-IV activity had an average of 34.88 ±6.66U/L. The final day mean DPP-IV activity was 32.72 ±7.94U/L two weeks after the initial trial. The ANOVA reported no significant difference (P= 0.85). The total coefficient of variation was 5%. CONCLUSION: Storage up to three weeks results in a stable and reliable DPP-IV activity value when measured using this fluorometric assay. These values fall within normal reference values presented by Durnix et al. (2001). Further studies should investigate if there is a time point past three weeks that yields the same reliability.Concurrent exercise, a combination of endurance and resistance exercise performed in succession, may compromise muscle hypertrophic adaptation induced by resistance training alone. However, little is known about the molecular signaling interactions underlying the change in skeletal muscle adaptation. PURPOSE: To investigate whether endurance exercise (EE) before or after resistance exercise (RE) affects molecular signaling associated with muscle protein synthesis, specifically the interaction between RE-induced mammalian target of rapamycin complex 1 (mTORC1) signaling and EE-induced AMP-activated protein kinase (AMPK) signaling, in an animal model. METHODS: Male Sprague-Dawley rats were divided into 3 groups: EE (treadmill, 25m/min, 60min) before RE (maximum isometric contraction via percutaneous electrical stimulation for 3 sec × 10, 5 sets) group, EE after RE group, or non-e...
