Fitness changes of naval women following aerobic based programs featuring calisthenic or circuit weight training exercises

Two research investigations were undertaken to determine the effects of experimental aerobic/circuit weight training (A/CWT) and standard Navy aerobic/calisthenic (A/CAL) training on fitness parameters.
Study I Subjects were 22 female officer and enlisted personnel aged 24 to 34 years (mean=28.2). The women followed a 10-week A/ CWT program working at an intensity of 60% of determined one repetition maximum (1RM). These women showed significant (p<0.05) improvements in dynamic muscular strength, muscular endurance, and stamina. Only upper torso static strength was unaffected by training.
Study IIParticipants were 115 female recruits aged 17 to 34 years (mean=20.4). They were randomly assigned to one of three training groups: 1) aerobic/calisthenic training (A/CAL) (N=58); 2) aerobic/circuit weight training at 40% (A/CWT-40) of maximum strength determined for a single repetition (1RM) of the lifting exercises (N=26); and 3) aerobic/circuit weight training at 70% (A/CWT-70) of determined 1RM (N=30).
Results showed that standard recruit A/CAL training did not significantly (p<0.05) enhance upper torso dynamic strength (except the lat-pull-down test) or stamina. A/CWT-70 elicited significantly (p<0.05) higher gains in several tests of upper torso strength than A/CAL or A/CWT-40. These results suggest that A/CWT offers a way to develop the required upper torso strength of Navy women.
