Article Report:Influence of Exercise Training In Weight Loss Among Men: by Kraemer et al 1999
This study was aimed at assessing the physiological impact of weight loss dietary regimen by using or not using physical exercises. The researchers concluded that weight- loss dietary regiment alongside resistance exercises, and aerobic exercises prevents the usual decrease in muscular power and fat-free mass.
The researchers matched thirty five overweight and obese men with a control group (C, N=6) or one of the dietary groups (D; N=8), a diet group that undertook aerobic exercises three times each week (DE; N=11). Finally there was a diet group which undertook both strength training and aerobic exercise at least three times a week (DE; N=10).
After three months, the DES, DE and D portrayed a significant and same decrease in body mass -9.90, -8.99, and -9.64 respectively. The body mass constituted 97%, 78% and 69% of the total reduction in body mass respectively. The group undergoing diet only portrayed a notable reduction in fat free mass. The 1-RM testing in squat exercises, and press increased the maximum strength for DES in squat exercises (+32.6%), and bench press (+19.6%).The O2 consumption among DE was significantly increased to (+24.8%) and DES to (+15.4%). The variation in performance from the 30-s Wingate test for the DES and DE was insignificant. D on the other hand, portrayed a notable decrease in mean power and peak output. There are no notable changes in basal concentration in BUN, serum glucose, testosterone, as well as high-density liprotein for the groups.
Findings from this study indicate that weight loss dietary regiment alongside resistance and aerobic exercises are capable of preventing a decrease in the muscular power, and fat-free mass. In addition, these factors are capable of augmenting high consumption of oxygen, and maximum strength when compared with weight loss that is induced by diet only.
