Physical fitness spurts in childhood: a study in boys
Pereira, Sara; Garbeloto, Fernando; Guimarães, Eduardo; Santos, Carla; Baxter‐Jones, Adam; Tani, Go; Freitas, Duarte; Bustamante, AlcibíadesThis study aimed to (1) estimate age-at-mid-growth spurt (age-at-MGS) in Portuguese boys from two different regions—the Azores islands and Viana do Castelo, and (2) identify spurts in a variety of physical fitness (PF) components aligned by age-at MGS in the two samples. A total of 176 (Azores, n = 91; Viana do Castelo, n = 85) boys aged 6 years old were followed annually to 10 years of age. Age-at-MGS and spur...
Physical fitness spurts in pre-adolescent boys and girls: Timing, intensity and...
Pereira, Sara; Santos, Carla; Tani, Go; Freitas, Duarte; Garbeloto, Fernando; Guimarães, Eduardo; Robinson, Leah E.; Baxter-Jones, AdamWe aim to (1) estimate age of attainment of the peak mid-growth spurt in stature (age-at-peak MGS) in pre-adolescent boys and girls; (2) identify the timing, intensity, and sequences of physical fitness (PF) spurts aligned by the age-at-peak MGS; and (3) identify any sex differences in PF spurts aligned by age-at peak MGS. The sample included 180 Portuguese children (90 girls) aged 6 to 10 years at study entry ...
Patterns of physical performance spurts during adolescence: a cross-cultural st...
Guimarães, Eduardo; Baxter-Jones, Adam D. G.; Pereira, Sara; Garbeloto, Fernando; Freitas, Duarte; Janeira, Manuel A.; Tani, Go; Katzmarzyk, Peter T.Background: Data relating physical performance to the timing of the adolescent growth spurt are lim ited. Aim: This study identifies: (i) age-at-peak height velocity (APHV), (ii) physical performance spurt patterns aligned to APHV; and (iii) cross-cultural and time patterns in Canadian, Brazilian and Portuguese boys. Subjects and methods: A total of 512 boys (131 Canadian, 250 Portuguese and 131 Brazilian), 8–1...
