This investigation assessed the physical characteristics, functional capacities, and body composition of 45 professional fire fighters, aged 23 through 49 years. Maximum oxygen uptake (VO2), Recovery Oxygen Uptake, arm and leg strength, all showed a negative linear relationship with age. On the other hand, percent body fat increased with age from 18% to(More)
Various situations present a challenge to determine oxygen uptake (VO2) accurately simply because of the restrictions imposed by the equipment employed. This investigation was undertaken to 1) compare a select number of recovery VO2 measurements with respect to their accuracy in estimating actual exercise VO2 and 2) to determine whether absolute workload or(More)
Hypoxic Training, which has been popular in swimming for the past few years, is more correctly called Controlled Breathing Swimming (CBS). This study investigated the acute effects of CBS on blood glucose (GL), lactate (LA), pH, PvCO2, and recovery oxygen uptake. Six male swimmers were studied in two separate swimming sessions using two breathing(More)
The purpose of this study was to compare the test result times of 3 different hockey skills with the individual player ratings of coaches. By making these comparisons to the control rating, each test was evaluated as a predictor of hockey ability. The hockey players were all between the ages of 12 and 20 years of age and all 90 players were competitive team(More)
Cardiac outputs were calculated on eight male college students while walking on a treadmill at controlled heart rate levels. The heart rate levels were maintained through the use of a heart rate controller (Quinton Model AI-607), standard deviations for heart rate in beats/min ranged from +/-2.1 at the heart rate level 110 to +/-3.2 at 170.

Isometric and isotonic endurance levels of both elbow flexors and knee extensors were tested during inspired gas mixtures of ca. 10%, 21% or 100% oxygen in nitrogen. The four work loads were set a 25, 50, 60 and 70% of maximal volitional isometric strength (IS). The isotonic exercise routine was carried out using weight lifting techniques of 20 repetitions(More)
