The aim of this study was to examine the hormonal and strength responses to different periodization models of resistance training in male athletes. Eighteen experienced resistance trained males were randomly assigned to either a block (BP; n=10; age: 23.7±2.9 yr; body mass: 78.5±11.3 kg; height: 1.77±0.05 m) or weekly undulating (WUP; n=8; age: 26.0±5.7 y; body mass: 78.9±12.4 kg; height: 1.79±...

In the current study, we evaluated the impact of exercise intensity on gender differences in upper-body poling among cross-country skiers, as well as the associated differences in aerobic capacity, maximal strength, body composition, technique and extent of training. Eight male and eight female elite skiers, gender-matched for level of performance by FIS points, carried out a 4-min submaximal, ...

OBJECTIVE To evaluate the prevalence and magnitude of weakness in patients receiving chronic mechanical ventilation and the impact of providing aggressive whole-body rehabilitation on conventional weaning variables, muscle strength, and overall functional status. DESIGN Retrospective analysis of 49 consecutive patients. SETTING Multidisciplinary ventilatory rehabilitation unit in an academi...

BACKGROUND Ataxia-telangiectasia (A-T) is a devastating human autosomal recessive disorder that causes progressive cerebellar ataxia, immunodeficiency, premature aging, chromosomal instability and increased cancer risk. Affected patients show growth failure, poor weight gain, low body mass index (BMI), myopenia and increased fatigue during adolescence. The prevalence of alterations in body comp...

STUDY DESIGN A cross-sectional study design was used. OBJECTIVE The objective was to examine the influences of body anthropometrics, axial disc area, and lifting strength on disc degeneration and to compare these with the effects of lifetime physical demands and age. SUMMARY OF BACKGROUND DATA Although recent studies have shown that heredity is a dominant factor in disc degeneration, the co...

Effect of four-month vertical whole body vibration on performance and balance. Med. Sci. Sports Exerc., Vol. 34, No. 9, pp. 1523–1528, 2002. Purpose: This randomized controlled study was designed to investigate the effects of a 4-month whole body vibration-interve...

BACKGROUND The objective of this study was to clarify the association of quadriceps muscle strength with knee pain using a large-scale, population-based cohort of the Research on Osteoarthritis/osteoporosis Against Disability (ROAD) study. METHODS From the 2566 subjects at the third visit of the ROAD study, the present study analyzed 2152 subjects who completed radiographic examinations and m...

We performed gene screening of the ciliary neurotrophic factor receptor (CNTFR) gene and genotyped three newly identified polymorphisms: C-1703T in the 5' promoter region, T1069A in intron 5, and C174T in exon 9. We studied the association of these CNTFR variants with muscle strength, mass, and body composition in 465 men and women (20-90 yr) from the Baltimore Longitudinal Study of Aging. Only...

The purpose of this study was to investigate the changes in the body composition, body size, muscle strength, and VO2max after 24 weeks of resistance or endurance training and detraining in young men. Thirty healthy college-aged men (20.4 ± 1.36 years) participated in the study. Subjects were assigned to resistance training group (RTG, n = 10), endurance training group (ETG, n = 10), and contro...

OBJECTIVE The aim of this study was to assess the effectiveness of a community-based, low-intensity exercise programme in older adults from socio-economically and historically disadvantaged communities. DESIGN Three community centres were selected: two were allocated to the same 20-week, twice-weekly exercise program (EX1, n=38; EX2, n=32); and a third to relaxation classes (control/CTL; n=21...
