    초록

    The specific role of different strength measures on mortality risk needs to be clarified to gain a better understanding of the clinical importance of different muscle groups, as well as to inform intervention protocols in relation to reducing early mortality. The aim of the systematic review and meta‐analysis was to determine the relationship between muscular strength and risk of cancer mortality. Eligible cohort studies were those that examined the association between muscular strength, as assessed using validated tests, and cancer mortality in healthy youth and adults. The hazard ratio (HR) estimates obtained were pooled using random effects meta‐analysis models. The outcome was cancer mortality assessed using the HR (Cox proportional hazards model). Eleven prospective studies with 1 309 413 participants were included, and 9787 cancer‐specific deaths were reported. Overall, greater handgrip (HR = 0.97, 95% CI, 0.92‐1.02; P =< .055; I 2 = 18.9%) and knee extension strength (HR = 0.98, 95% CI, 0.95‐1.00; P =< .051; I 2 = 60.6%) were barely significant associated with reduced risk of cancer mortality. Our study suggests that higher level of muscular strength is not statistically associated with lower risk of cancer mortality.

    초록

    The myotendinous junction (MTJ) is at high risk of strain injuries, due to high amounts of energy that is transferred through this structure. The risk of strain injury is significantly reduced by heavy resistance training (HRT), indicating a remodeling capacity of MTJ. We investigated the degree of remodeling of muscle fibers near the human MTJ. In 8 individuals, samples were taken from the semitendinosus and gracilis MTJ and they were stained immunohistochemically for myonuclei (DAPI), fibroblasts (TCF7L2), and satellite cells (CD56). A high portion of the muscle fibers adjacent to the MTJ contained a centrally located myonucleus (47 ± 8%, mean ± SD) and half of the muscle fibers were CD56 positive. The number of satellite cells and fibroblasts were not higher than what has previously been reported from muscle bellies. The immunohistochemical findings suggest that the rate of remodeling of muscle fibers near the MTJ is very high. The finding that there was no increased number of satellite cells and fibroblasts could be explained as a dynamic phenomenon. The effect of HRT should be evaluated in a randomized setting.

    초록

    This study examined the trajectories of elite swimmers’ recovery‐stress states and cardiac vagal‐related markers during a 3‐month training period preceding the national championship and their within‐person relationships with perceived control. A Multilevel Growth Curve Analysis (MGCA) approach was used with 21 male elite swimmers. Four waves of assessments of psychological (stress, recovery, perceived control) and physiological (heart rate recovery, heart rate variability) markers were completed during a 3month training preparation leading to a major competition. Results of MGCA revealed (a) a significant positive linear effect of time (ie, linear increase over time) and a significant negative quadratic effect of time (ie, inverted U shape over time) on perceived stress whereas the opposite pattern of results was observed for perceived recovery; and (b) a significant positive linear effect of time for nHRR60. Both at level 1 (within‐person level of analysis) and 2 (between‐person level of analysis), perceived control was (a) positively associated with athletes’ perceived recovery and parasympathetic markers (ie, MeanRR; pNN50); and (b) negatively related to swimmers’ perceived stress. Results also indicated that within‐person interactions of perceived control with time reached significance for general recovery and HRV. Finally, within‐person interaction of perceived control with squared time reached significance for subjective sport‐specific and total stress. Overall, this study provided insights into the key role played by perceived control on both psychological and physiological markers related to recovery‐stress states’ levels during the 3‐month training period preceding the national championship.

  7. [해외논문]   Interseason variability in isokinetic strength and poor correlation with Nordic hamstring eccentric strength in football players   SCI SCIE

    초록

    In elite sport, the use of strength testing to establish muscle function and performance is common. Traditionally, isokinetic strength tests have been used, measuring torque during concentric and eccentric muscle action. A device that measures eccentric hamstring muscle strength while performing the Nordic hamstring exercise is now also frequently used. The study aimed to investigate the variability of isokinetic muscle strength over time, for example, between seasons, and the relationship between isokinetic testing and the new Nordic hamstring exercise device. All teams (n = 18) eligible to compete in the premier football league in Qatar underwent a comprehensive strength assessment during their periodic health evaluation at Aspetar Orthopaedic and Sports Medicine Hospital in Qatar. Isokinetic strength was investigated for measurement error, and correlated to Nordic hamstring exercise strength. Of the 529 players included, 288 players had repeated tests with 1/2 seasons between test occasions. Variability (measurement error) between test occasions was substantial, as demonstrated by the measurement error (approximately 25 Nm, 15%), whether separated by 1 or 2 seasons. Considering hamstring injuries, the same pattern was observed among injured (n = 60) and uninjured (n = 228) players. A poor correlation ( r = .35) was observed between peak isokinetic hamstring eccentric torque and Nordic hamstring exercise peak force. The strength imbalance between limbs calculated for both test modes was not correlated ( r = .037). There is substantial intraindividual variability in all isokinetic test measures, whether separated by 1 or 2 seasons, irrespective of injury. Also, eccentric hamstring strength and limb‐to‐limb imbalance were poorly correlated between the isokinetic and Nordic hamstring exercise tests.

    초록

    High levels of sedentary time have been detrimentally linked to health outcomes. Differentiating sitting from lying may help to further understand the mechanisms associated with these health impacts. This study compares the inter‐method agreement between the “single‐monitor” method (thigh‐worn activPAL 3 TM ) and a more robustly validated “dual‐monitor” method (trunk and thigh‐worn activPAL 3 TM ) in their classifications of sitting and lying under free‐living conditions. Thirty‐five participants (20‐50 years) wore two activity monitors (thigh and trunk) for 24 hours. Total time spent lying and sitting was calculated for both methods, and agreement was determined using ICC and Bland‐Altman methods. As there was no gold standard, further data were collected from five participants during structured activities that were designed to challenge classification, to better understand any disagreement between the methods. ICCs were 0.81 for sitting time and 0.64 for lying time. The single‐monitor method detected less lying time than the dual‐monitor method, with a mean difference of −25 minutes (95% agreement limits: −172 to 221 minutes), including three cases with extreme disagreement (mostly in daytime lying classification). The additional data collection suggested a major source of disagreement was failure of the single‐monitor method to identify lying that involved no rotation around the longitudinal axis. In conclusion, there was some agreement between the single‐ and dual‐monitor estimates of lying time under free‐living conditions, but measures were not interchangeable. The main disagreement was in how the methods classified daytime lying and lying tasks involving no lateral movement. Both methods yield promise for measuring time in bed.

    Our objective was to determine associations between retinal vascular caliber and physical activity (PA) in a school‐based child cohort. In a prospective study, we created a childhood cumulative average PA‐index using objectively measured PA (accelerometry) assessed at four periods between 2009 and 2015. Cumulative exposure to PA intensities was estimated. Cross‐sectional examinations on biomarkers, anthropometry, and ophthalmological data including retinal fundus photographs were performed in 2015. Semi‐automated measurements of retinal vascular diameters were performed and summarized into central retinal arteriolar and venular equivalents (CRAE, CRVE). We included 307 participants. Mean age in 2015 was 15.4 years (0.7). The mean CRAE and CRVE were 156.5 μm (2.8) and 217.6 μm (7.7), respectively. After adjusting for age, gender, and axial length, more time in PA was independently related to thinner retinal venules (β‐coefficient = −1.25 μm/%, 95% confidence interval = −2.20, −0.30, P P P P = .04). We concluded that children with higher PA in childhood had thinner retinal venular caliber. Our results suggest that PA during childhood positively impacts the retinal microcirculation and that retinal vascular analysis may be a possible assessment to detect microvascular impairments in children with an increased risk of future cardiovascular disease.

    Health behaviors in youth can predict the same behaviors later in life, but the role of sport participation in predicting healthy lifestyle habits is unclear. This study aimed to investigate the association between participation in organized youth sport and adult healthy lifestyle habits. Data from the longitudinal Cardiovascular Risk in Young Finns Study (YFS) with a 28‐year follow‐up were used. The participation in sport‐club training sessions was self‐reported by 9‐18‐year‐olds in 1983 and 1986 (n = 1285). During 2011, participants (aged 37‐43‐year old) reported their smoking status, alcohol consumption, fruit and vegetable consumption, and physical activity. Odd ratios (OR) were calculated using logistic regression, to examine how participation in organized youth sport was associated with having three or four versus fewer (0‐2) healthy habits in adulthood. Participants who were active in youth sport in both 1983 and 1986 had almost two times greater odds of having three or four healthy habits in adulthood than those who were not active at both time points (OR: 1.75, 95%CI: 1.11‐2.76). When the analyses were stratified by sex, the findings were statistically significant among women (OR: 2.13, 95%Cl: 1.13‐3.99) but not men (OR: 1.27, 95%CI: 0.63‐2.58). The results suggest that participation in organized youth sport could promote healthy lifestyle choices.
