M. Barnekowbergkvist et al., DEVELOPMENT OF MUSCULAR ENDURANCE AND STRENGTH FROM ADOLESCENCE TO ADULTHOOD AND LEVEL OF PHYSICAL CAPACITY IN MEN AND WOMEN AT THE AGE OF 34 YEARS, Scandinavian journal of medicine & science in sports, 6(3), 1996, pp. 145-155
This study investigated the development of muscular endurance and stre
ngth from the age of 16 to the age of 34 and the fitness components at
the age of 34 in men and women. A randomly selected group consisting
of 220 boys and 205 girls was tested in 1974 and reinvestigated 18 yea
rs later. Muscular endurance and strength increased significantly in 4
of the 5 remeasured tests for the men; bench press increased by 58%,
two-hand lift by 20%, hand grip by 16% and Sargent jump by 8%. For the
women there was a significant increase in bench press and two-hand li
ft by 25% and 7% respectively, but hand grip and Sargent jump decrease
d with a few per cent. The hip and trunk flexion test, sit-up, decreas
ed remarkably in both men (58%) and women (78%). At the age of 16 phys
ical capacity was significantly higher in all tests in the men. This w
as also the situation at the age of 34 except for VO2 max in ml . kg(-
1) . min(-1) and muscular endurance in the back muscles. There were no
differences in flexibility between men and women except for less flex
ibility in the hamstring muscles in the men. The result of the balance
test was significantly better in the men.
