Results Strong evidence was found for an inverse association between MF and total and central adiposity , and CVD and metabolic risk factors .
Strong evidence was also found for a positive association between MF and bone health and self-esteem .
Conclusion The findings of this review highlight the importance of developing MF in youth for a number of health-related benefits
Background Physical fitness during childhood and adolescence has been identified as an important determinant of current and future health status .
While research has traditionally focused on the association between cardio-respiratory fitness and health outcomes , the association between muscular fitness ( MF ) and health status has recently received increased attention .
Objective The aim of this systematic review and meta- analysis was to evaluate the potential physiological and psychological benefits associated with MF among children and adolescents .
Isometric endurance of the back extensors in school-aged adolescents with and without low back pain.
BACKGROUND AND OBJECTIVE Studies on back extensor endurance in adolescents are scarce . This study sought to establish reference data and pattern of back extensor endurance in school-aged adolescents with and without low-back pain ( LBP ) from Nigeria . SUBJECTS AND METHODS This study recruited 625 adolescents aged 11 to 19 years from eight r and omly selected secondary schools . The modified Biering-Sørensen test of Static Muscular Endurance ( BSME ) was used to assess isometric endurance of the back extensors . Demographic and anthropometric data were collected . A modified LBP question naire was used to assess the presence of LBP . Descriptive and inferential analyses were used to analyze data . Significance was set at 0.05 alpha-level . RESULTS The mean isometric holding time ( IHT ) of all the participants was 132.9 $ \pm$ 65.6 . Males had significantly higher significant ( p=0.026 ) IHT than females . Adolescents without LBP had a higher significant IHT ( p=0.042 ) than those with reported history of previous LBP and those with present LBP ( p=0.000 ) respectively . Using percentile values , poor endurance was defined as IHT that is < 90.0 s and < 67 s for males and females respectively ; medium endurance was defined as IHT that ranged between 90 and 193 s and 67 and 170 s for males and females respectively while good endurance was defined as IHT that is > 193 s and > 170 s for males and females respectively . IHT was significantly related to each of body mass index , hip circumference and waist-to-hip ratio ( p < 0.05 ) . CONCLUSION Isometric back extensors endurance in Nigerian adolescents was comparable to the original Biering-Sørensen mean value . Majority of the participants had medium endurance performance with the back endurance pattern in the ratio 1:2:1 . Male had higher isometric back extensors endurance than females . Decreased isometric back extensors endurance was associated with the presence of LBP in adolescents
