The effects of sodium bicarbonate and sodium citrate on 600 m running time of trained females.

The effects of sodium bicarbonate and sodium citrate ingestion on 600 m running performance were assessed in 11 female track athletes and four trained female non-athletes. The subjects ingested either sodium bicarbonate (NaHCO3), sodium citrate or placebo approximately 2.5 hrs prior to the test runs in doses of 0.

Physiological characteristics of female 100 metre sprinters of different performance levels.

The purpose of this study was to compare physiological characteristics of three different levels of 100 m female sprinters. The 30 subjects in this study (20 female track athletes and 10 recreationally trained females) were assigned, according to their 100 m running time, to one of three different groups: "Fast" (11.8 +/- 0.

Treadmill exercise electrocardiography in the elderly with physical impairments.

Treadmill testing (TMT) was performed on 76 frail but ambulatory subjects, between 64 and 84 years of age, who had common health problems contributing to physical limitations but had no clinically apparent heart disease. The subjects achieved a mean symptom-limited maximal heart rate of 140.1 +/- 2.

Effects of exercise training on common femoral artery blood flow in patients with intermittent claudication.

Exercise training is a commonly used rehabilitative therapy for patients with intermittent claudication (IC). However, it is not known whether blood flow through the major conduit vessel of the leg, the common femoral artery (CFA), increases with exercise training. We tested the hypothesis that peak CFA blood flow will increase with a supervised, lengthy, and individualized exercise training program.

Physical exercise increases natural cellular-mediated tumor cytotoxicity in elderly women.

The influence of acute treadmill exercise on natural killer (NK) cell tumor cytotoxicity in vitro was studied in elderly women after participation in a program of physical exercise training (PET) (n = 7) or after participation in a paralleling nonexercise control (NEC) condition (n = 7). The two study groups were equated (p greater than 0.05) according to age, percent total body fat, functional status as measured by multi-inventory ranking, and exercise capacity.
