Moderate energy restriction with high protein diet results in healthier outcome in women
Abstract Background The present study compares two different weight reduction regimens both with a moderately high protein intake on body composition, serum hormone concentration and strength performance in non-competitive female athletes. Methods Fifteen normal weighted women involved in recreational resistance training and aerobic training were recruited for the study (age 28.5 ± 6.3 yr, height 167.0 ± 7.0 cm, body mass 66.3 ± 4.2 kg, body mass index 23.8 ± 1.8, mean ± SD). They were randomized into two groups. The 1 KG group (n = 8; energy deficit 1100 kcal/day) was supervised to reduce body weight by 1 kg per week and the 0.5 KG group (n = 7; energy deficit 550 kcal/day) by 0.5 kg per w…
Jääkiekon lajianalyysi ja harjoittelun perusteet
Huovinen, Heikki Tuomas 2009. Jääkiekon lajianalyysi ja harjoittelun perusteet. Valmennus- ja testausopin jatkokurssi, Valmentajaseminaari. Liikuntabiologian laitos, Jyväskylän yliopisto, 51 s. Tämän työn tarkoituksena oli koota tietoa jääkiekkoharjoittelun kokonaisuudesta ja jääkiekon fysiologisista vaatimuksista. Työ perustuu pääasiallisesti tieteellisiin julkaisuihin ja osin jääkiekkovalmennuksen ammattilaisten luentoihin ja henkilökohtaisiin tiedonantoihin. Jääkiekon fysiologiset vaatimukset ovat muuttuneet ajan kuluessa. Jääkiekkoilijat ovat tänä päivänä huomattavasti paremmassa fyysisessä kunnossa kuin pari vuosikymmentä sitten (Cox ym. 1995). Tiikkajan (2002b) tutkimus kuvaa tämän pä…
Body Composition and Power Performance Improved After Weight Reduction in Male Athletes Without Hampering Hormonal Balance
The aim of this study was to investigate the effects of a 4-week weight reduction period with high protein and reduced carbohydrate intake on body composition, explosive power, speed, serum hormones, and acid-base balance in male track and field jumpers and sprinters. Eight participants were assigned to a high weight reduction group (HWR; energy restriction 750 kcal·d) and 7 to a low weight reduction group (LWR; energy restriction 300 kcal·d). Energy and carbohydrate intake decreased significantly (p ≤ 0.05) only in HWR by 740 ± 330 kcal·d and 130 ± 29 g·d, respectively. Furthermore, total body mass and fat mass decreased (p ≤ 0.05) only in HWR by 2.2 ± 1.0 kg and 1.7 ± 1.6 kg, respectively…
