One article on PainSci cites Graves 1988: Strength Training Frequency
PainSci commentary on Graves 1988: ?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided wherever possible.
Graves et al studied 50 men and women accustomed to strength training and tested them on 12 weeks of reduced training frequency, going from 2 or 3 days per week to 0, 1 or 2 days per week. Those reduced to zero lost strength as expected (about 70% over the 12 weeks), but for those who merely reduced their frequency? No loss at all: “Strength values for subjects who reduced training to 2 and 1 days/week were not significantly different … . These data suggest that muscular strength can be maintained for up to 12 weeks with reduced training frequency.”

Twenty-four men and 26 women (25±5 years) participating in 10 weeks (n = 27) and 18 weeks (n = 23) of variable resistance strength training programs were recruited to complete 12 weeks of reduced training. Training consisted of one set of 7-10 bilateral knee extensions performed to volitional failure. Prior to the reduced training phase of the project, the subjects were training either 2 days·week-1 (n = 23) or 3 days·week-1 (n = 18). The subjects who trained 3 days·week-1 reduced training frequency to 2 days·week-1 (n = 9), 1 day·week-1 (n = 7), or 0 days·week-1 (n = 2). The subjects who trained 2 days·week-1 reduced training frequency to 1 day·week-1 (n = 12) or 0 days·week-1 (n = 11). Nine subjects served as controls and did not train. Isometric knee extension strength was assessed at 9, 20, 35, 50, 65, 80, 95, and 110 degrees of knee flexion on two separate occasions prior to and immediately post-training and following reduced training. After training, mean relative increases in peak isometric knee extension strength and dynamic training weight were 21.4%±17.5% (P < 0.01) and 49.5%±14.7% (P < 0.01), respectively. The subjects who stopped training (0 days·week-1) lost 68% (P < 0.01) of the isometric strength gained during training. Strength values for subjects who reduced training to 2 and 1 days·week-1 were not significantly different (P> 0.05) from post-training strength values. These data suggest that muscular strength can be maintained for up to 12 weeks with reduced training frequency.
