Variable resistance versus constant resistance strength training in adult males.

Changes in strength, body composition and anthropometric measures for groups training with constant resistance and variable resistance training procedures was compared. Thirty-six male volunteers were randomly assigned to one of three groups: Constant Resistance (CR), Variable Resistance (VR) and Control (C). Strength training was conducted 3 days per week, 45 min per day, for 10 weeks. The results demonstrated that both the CR and the VR groups increased muscular strength. The CR group demonstrated significant increases in strength over the VR group when strength was assessed by CR procedures. Conversely, the VR group demonstrated significant increases in strength over the CR group when strength was assessed by VR procedures. Neither group exhibited superiority over the other relative to changes in body composition and anthropometric measures. The significance of these results is discussed.

Energy cost of circuit weight training.

The metabolic cost of circuit weight training was determined in a group of 20 men and 20 women, 17 to 36 years of age, who volunteered to participate in this study. Performing 3 circuits (10 stations/circuit), using a work (30-sec) to rest (15-sec) ratio of 2:1, and a total exercise time of 22.5 min, the energy expenditure was found to be highly related to body weight (r = 0.84 and r = 0.67 for men and women respectively). The average gross energy expenditure was 539.7 and 367.5 kcal/hr. (9.0 and 6.1 kcal/min) for the men and women respectively, but was 7.0 and 6.0 kcal/kg-hr when expressed relative to body weight, and 8.1 and 8.2 kcal/kg(LBW)-min when expressed relative to lean body weight. Thus, when body composition was considered, there were essentially no differences in the energy expenditure for males and females.

Physiological alterations consequent to circuit weight training.

The efficacy of a 10-week program of circuit weight training to elicit specific physiological alterations was evaluated in a group of men (n = 16) and a group of women (n = 12), with an additional group of men (n = 10) and a group of women (n = 11) serving as controls. The circuit consisted of 10 stations performed on a Universal Gym, 3 circuits per day (approximately 22.5 min/day), 3 days/week. The subjects exercised at 40-55% of 1-RM, executing as many repetitions as possible in 30 sec on each of the lifts, followed by a 15 sec rest as the subject moved to the next station. Following the training program, the experimental groups demonstrated significant increases in lean body weight, flexed biceps girth, treadmill endurance time, VEmax (women only), Vo2max in ml/kg-min (women only), flexibility and strength. Significant decreases were found in selected skinfold measurements, and in resting heart rate (control group showed similar decreases). No change was found in body weight or in relative or absolute body fat. Generally, the women exhibited equal or greater changes when compared to the men for all variables assessed, which could be a function of their lower initial starting levels, or a more intense training program. It was concluded that circuit weight training is a good general conditioning activity, i.e., attends to more than one component of fitness.

Physiological responses of fire fighting recruits to high intensity training.

Data were obtained for 20 fire department recruits before and after a ten-week training program. Training consisted of interval running and circuit weight training. At the conclusion of the training program several parameters were examined. Total work capacity assessed on a bicycle ergometer significantly increased (27.3%) with a concomittent increase in maximum oxygen uptake (33.2%). Physical performance tests given showed marked increases in 12 foot rope climb, 600 yard run, push-ups, sit-ups and leg-lifts. Physical strength also showed significant increases for the bench press (18.5%), military press (19.4%) pulldown (11.7%) biceps curl (16.2%) and leg press (18.7%). Training of this nature also brought about significant changes in body composition of the recruits. The subscapula and abdomen skinfold sites showed significant decreases of -9.6% and -11.9% respectfully. Body segment circumferences showed significant changes for shoulder, thigh, flexed biceps and abdomen. The skinfold and circumference measures reflected changes in lean body weight (2.6%), absolute body fat (-13.4%), and relative body fat (-13.7%). It has been shown that interval training and circuit weight training significantly increase the physical performance capacities of the recruits. It has been suggested, due to the tremendous cost to the county and city agencies as well as to the aspiring recruit, that a preliminary physical training program be implemented to reduce the drop-out rate of recruits during the tower training drills.

Isokinetic vs isotonic strength training in adult men.

The differences in changes in strength, body composition, anthropometric measurements and selected motor performance tasks, between groups, trained isotonically and isokinetically were compared. Thirty-six male volunteers were randomly assigned to one of four groups: isotonic; isokinetic low speed contraction; isokinetic high speed contraction; and control. Strength training was conducted three days per week, 40 minutes per day for eight weeks. The results demonstrated a clear superiority of the isokinetic training procedures over the isotonic procedures relative to strength, antrhopometric measures and motor performance tasks. The three training groups exhibited similar changes in body composition. The isokinetic high speed group demonstrated the greatest gains overall. The significance of these results is discussed.
