Forty women and 25 men volunteered as subjects. Subjects performed a three stage cycle ergometry test at power outputs of 0,360, and 540 kgm·min−1 respectively while their oxygen consumption was measured. The subjects also had several anthropometric, body composition, and knee muscle force measures made. Results indicated that most of the variables were significantly related to cycling VO2 (p ≤ .05). Fat‐free mass (FFM) and fat‐free thigh mass (FFTM) correlated the highest and identically with VO2 (r = .80, .67, and .57) at each respective power output listed above. Using stepwise multiple regression only one variable, FFTM, was associated with the equation for each power output.

Subjects were 14 trained and experienced female distance runners whose mean (±SD) age, mass, percent body fat, and VO2 max were 31.3 ± 2.8 yr, 58.5 ± 6.7 kg, 17.5 ± 3.9 percent, and 48.9 ± 4.9 ml· min−1 · kg−1 respectively. Results indicated that ventilation threshold (VT), velocity at VO2 max (vVO2 max), V02max, 50 m sprint time, and peak knee extension torque at 400 deg· sec−1 were significantly correlated with 10 km run time (p ≤ .05). Stepwise multiple regression indicated that VT was the strongest single predictor explaining 48% of the variance while 50 m sprint time increased the explained variance to 67.2% (SEE = 1.40 min). The regression equation developed was: Y' = 48.65 ‐ .270 (VT ml· min−1 · kg−1 + .90 (50m in sec).

Comparison of the results of the field test of walking was made both in patients with different degrees of spine deformity as well as with reference values of a healthy population using the same test. Judgment of the validity of the test for use in longterm supervision was attempted. A total of 33 girls with idio‐pathic scoliosis were examined (before operation) and divided into group A (n = 8; age 15.1 ± 2.8; angle according to Cobb <60°) and group B (n = 25; age 14.7 ± 2.1; ≥60). Spirometry, acid base balance (ABB [BE, cH+]) in blood, oxygen consumption (VO2), and heart rate (HR) were examined during the walking test; in addition, the functional response, a performance time, and a fitness index were evaluated. The test was performed without subjective complaints (RPE x= 11.4) or any significant functional and ABB change.

AMB and SEMI subjects exercised on alternating days for 30 minutes, at 55‐60% VO2max using either a commercially available recumbent or upright combination leg/arm bicycle ergometer. At the end of 12 and 24 weeks, exercising subjects were re‐evaluated. The C group was only re‐evaluated at 24 weeks. The results show that the AMB and SEMI groups experienced a +20% and +5% improvement in VO2max, respectively. The C group averaged a 12% decline in VO2max during the 6 months.
