Peak height velocity in young athletes: A longitudinal meta-analysis

Journal of Sports Sciences, 2023
The present longitudinal meta-analysis aimed to estimate the growth curves and age at peak height velocity (PHV) in young male athletes, considering anthropometric data from available longitudinal studies. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, studies with repeated measurements in young ...

Prediction of the Crankshaft Phenomenon by Peak Height Velocity

Spine, 1997
Retrospective review.To evaluate the relation of the peak height velocity with the occurrence of the crankshaft phenomenon after posterior arthrodesis and instrumentation in idiopathic scoliosis.Although patients with closed triradiate cartilages are unlikely to exhibit the crankshaft phenomenon after a posterior spinal fusion and instrumentation, open

A new family of mathematical models describing the human growth curve—Erratum: Direct calculation of peak height velocity, age at take-off and associated quantities

Annals of Human Biology, 2013
A new family of mathematical functions to fit longitudinal growth data was described in 1978. The ability of researchers to directly use parameters as estimates of age at peak height velocity resulted in them overlooking the possibility of directly ...

Correlates of the Peak Height Velocity in Girls With Idiopathic Scoliosis

Spine, 2006
Prospective longitudinal.Determine correlates of the peak height velocity (PHV) in girls with idiopathic scoliosis.Only identifiable retrospectively, the PHV is the most useful known maturity marker in idiopathic scoliosis. Clinically useful correlates are needed to make PHV timing helpful.A total of 24 immature girls with idiopathic scoliosis were ...

Measurement of Growth Velocity and Peak Height Velocity in Teenagers

1984
As part of a longitudinal study ‘Growth and Health of Teenagers’ the authors measured height and weight of 233 boys and girls on twelve occasions at four-month intervals (Kemper et al., 1982).

Using the Sauvegrain Method to Predict Peak Height Velocity in Boys and Girls

Journal of Pediatric Orthopaedics, 2008
Correlating peak height velocity (PHV) with assessments of skeletal maturity has important implications in the treatment of scoliosis and other pediatric orthopaedic disorders. This study aims to compare the appearance of the elbow to the PHV in both boys and girls.We selected 20 children who participated in the Brush Inquiry, a comprehensive study of ...

The Relationship of Physical Activity and Peak Height Velocity in Children

2022
The case of stunting in Indonesia is number one in ASEAN. The stuntingindicator can be predicted by height and weight; the gene, nutrition, health, andphysical activity also contributed to development and growth. The appropriatephysical activity and engagement in sports can help to increase growth spurt inchildren.

Prediction of maturity offset and age at peak height velocity in a longitudinal series of boys and girls

American Journal of Human Biology, 2020
AbstractBackgroundPredicted maturity offset, defined as time before peak height velocity (PHV) is increasingly used as an indicator of maturity status in studies of physical activity, fitness, and sport.ObjectiveTo validate maturity offset prediction equations in longitudinal samples of boys and girls.MethodsThe original and modified maturity offset ...

Relationship of Peak Height Velocity to Other Maturity Indicators in Idiopathic Scoliosis in Girls*

The Journal of Bone and Joint Surgery-American Volume, 2000
Our aim was to compare height velocity data, obtained from clinical height measurements, for girls who had idiopathic scoliosis with the data for adolescents who did not have scoliosis. We also compared the growth data with chronological age, menarchal age, and Risser sign in terms of their accuracy in the prediction of growth and progression of the ...

Relationship of Calcaneal and Iliac Apophyseal Ossification to Peak Height Velocity Timing in Children

Journal of Bone and Joint Surgery, 2015
Ossification of the calcaneal apophysis has never been fully characterized. We examined the ossification sequence of the calcaneus in relation to ossification of the iliac apophysis and the timing of the peak height velocity (PHV).Ninety-four healthy children (forty-nine girls and forty-five boys), from three to eighteen years old, were followed ...
