dc.description.abstract | There is little
study into the effects of reducing strength training below the
recommended twice weekly frequency, particularly in older
women, despite the possibility that individuals will encounter
periods of reduced training frequency. The purpose of the
present study was to determine the effects of a period of
reduced training frequency on maximum strength and muscle
mass of the lower limbs in comparison with the recommended
training frequency of twice per week. After an initial 12-week
period, where all subjects trained twice per week, a reduced
strength training group (RST) trained once per week, whereas
another strength training group (ST) continued to train twice
per week for 24 weeks. A nontraining age-matched control
group (CON) was used for comparison. All subjects were
tested for leg press 1-repetition maximum (1RM), electromyogram (EMG) amplitude of vastus lateralis and medialis, and
quadriceps cross-sectional area (CSA) measured by panoramic ultrasound at weeks 0, 12, and 36. Both ST and RST
continued to increase 1RM during the reduced training frequency period compared with control (;8% and ;5% vs.
;23%, respectively; p # 0.05). Accompanying these
changes were significant increases in EMG amplitude in both
ST and RST (p # 0.05). However, the initial gains in quadriceps CSA made from week 0 to week 12 in RST were lost
when training once per week (RST ;25%). Therefore,
reduced training frequency in this population does not
adversely affect maximum strength or muscle activity but can
negatively affect muscle mass, even reversing training-induced
gains. Older individuals not training at least twice per week
may compromise potential increases in muscle mass, important in counteracting effects of aging. | fi |
