  • Transcutaneous electrical muscle stimulation does not alter regional arm adiposity and muscularity

    Open AccessBetsy A Keller, Frank I KatchARTICLEAmerican Journal of Human Biology1998

    The present study evaluated the effects of an electrical muscle stimulation (EMS) training protocol claimed to elicit site-specific fat reduction and muscle hypertrophy. The protocol includes 6 weeks (3 sessions/week, 10 contractions/session) of high frequency (2500 Hz) transcutaneous EMS training on upper arm muscle and fat tissue. Two groups of 10 subjects were stimulated either on the dominant biceps brachii (B) or triceps brachii (T). The non…

  • New approach for estimating excess body fat from changes in abdominal girth

    Open AccessFrank I Katch, Victor L Katch et al.ARTICLEAmerican Journal of Human Biology1990

    A new method is proposed for determining changes in percent body fat (%BF) based on the difference between an initial value for abdominal girth (AG) and a calculated “target” AG based on a desired %BF. Group data from large‐scale anthropometric surveys in the military were used to derive specific reference values for Q, defined as the ratio of AG at a desired %BF to F(√BM kg /Ht m ). For an individual, Q*F resulted in an AG that corresponded to a…

  • Validity of the Mellits and Cheek method for body-fat estimation in relation to menstrual cycle status in athletes and non-athletes below 22 per cent fat

    Open AccessFrank I Katch, Deborah L SpiakARTICLEAnnals of Human Biology1984

    The present experiment tested the hypothesis that 22% body fat based on the Mellits and Cheek (1970) regression equation is a minimum or 'trigger' level of fatness required to maintain regularity of menstrual cycles. The validity of the regression equation was cross-validated against densitometric estimates of body fat in 30 athletes (track, gymnastic, crew) and 30 non-athletes who were below 22% fat. For the total sample, the validity correlatio…

  • Contribution of breast volume and weight to body fat distribution in females

    Open AccessVictor L Katch, Barbara Campaigne et al.ARTICLEAmerican Journal of Physical…1980Cited by: 6References: 10

    Breast volume and body composition were measured in 45 adult females to determine the contribution of breast weight and breast volume to total body fat. Plaster casts were filled with sand of known density to obtain breast volume. Breast weight was computed as breast volume times its density. The correlation between total breast volume and percent body fat was r = .40. Breast weight ( X = 484 grams) accounted for 3.5 percent of the total weight o…

  • Measurement of breast volume in females

    Open AccessBarbara N Campaigne, Victor L Katch et al.ARTICLEAnnals of Human Biology1979

    Breast volume measurements were made on 47 adult subjects using a casting method. After drying, fast-setting plaster casts were filled with sand of known density to a level approximating the curvature of the chest wall. The reliability of both sand filling and casting proved to be high, r = 0.97, and r = 0.99, respectively. The total variable error was 10.2%. The effects of position (standing versus lying) was investigated in a separate sample of…
