The authors investigated lactic anaerobic metabolism in handball players during practice games. Seven players aged 18-21, belonging to second division league clubs, took part in the study. In the laboratory, VO2 max and the onset of blood lactate accumulation (OBLA) were determined with progressive maximal ergocycle tests. On the field, ...

Eight well trained marathon skaters performed all-out exercise tests during speed skating on ice and roller skating. To compare these skating activities in relation to the concept of training specificity, relevant physiological (VO2, VE, RER and heart rate) and biomechanical variables (derived from film and video analysis) were measured. There ...

The purpose of the study was to evaluate the early anatomic and functional changes of the left ventricles in junior freshman non-professional athletes just beginning specific regular training programs for 6 different types of sport. Forty-nine males (mean age 20 +/- 6 years) and 9 sedentary controls were studied by ...

A model was developed to identify the characteristics of long jumping technique that determine the distance of the jump. The performances of the finalists in the TAC (U.S. national) Championships were recorded cinematographically and the best trials analyzed. The results indicated that the relative lengths of the last two strides ...

The finger extension game was designed in response to a learning exercise by two students on preclinical assignment. It is an activity designed to facilitate the rehabilitation process of the finger extensors on a subcortical level. Occupational therapy literature emphasizes exercise techniques rather than incorporating activities with exercise. This game ...

Soccer is characterised as a high intensity, intermittent non-continuous exercise. Players cover approximately 10 km of ground per game, of which 8 to 18% is at the highest individual speed. In higher levels of competition there is a greater number of tackles and headings plus a greater percentage of the ...

Ten well-trained male volleyball players performed one-legged and two-legged vertical countermovement jumps. Ground reaction forces, cinematographic data, and electromyographic data were recorded. Jumping height in one-legged jumps was 58.5% of that reached in two-legged jumps. Mean net torques in hip and ankle joints were higher in one-legged jumps. Net power ...

IgA levels in saliva differed 15-fold between different individuals. The correlation between IgA in repeated stimulated saliva samples was good in both a short and a 2-yr period. The correlation between resting and stimulated samples was low, in particular when output of IgA over time was considered. Physical exercise affected ...

The extent to which different mechanical baseball-batting devices used during a rest affected performance immediately after rest (warm-up decrement) was examined. Difference scores between the average of prerest Trials 8, 9, and 10 and each of 10 postrest trials were used to determine the presence of warm-up decrement. It was ...

We describe here techniques designed to aid both the physically and mentally handicapped. T.V. games and exercises for the handicapped have been designed and tested with patients. The system initially consisted of a central game box with a microprocessor, interchangeable memory cards, and body joint angle transducers which operate with ...

In 18 trained football players, blood samples were collected before a football match, at half-time, at the end, and 45 and 90 min after the end of the match. The testosterone (T) level showed a decrease in the rest period. Dihydrotestosterone (DHT) increased during the match, but returned to initial ...
Viitasalo J T - - 1984
To investigate the influence of training on the isometric force-time (f-t) characteristics and on dynamic force production, eight Finnish male high jumpers were tested six to seven times during a twelve month period. The variations in the isometric maximal force, in the rate of isometric force development (RFD), as well ...

Hamstring/quadriceps ratios were assessed on 60 intercollegiate football players at functional speeds of 90, 180, and 300 deg/sec on the Cybex II. The ratio rose as velocity of exercise increased and the quadriceps was stronger than the hamstrings at all speeds. The flexor/extensor ratio differed bilaterally at all speeds with ...
Kircher M A - - 1984
Perceived exertion during the performance of purposeful and nonpurposeful activity was studied in 26 women. The subjects acted as their own controls in the performance of both kinds of exercise. The two exercises were jumping rope, defined as a purposeful activity, and jumping in place without a rope, defined as ...
Northcote R J - - 1983
Ambulatory electrocardiography was carried out in 21 healthy, fit, male squash players (aged 23-43 years) before, during, and after match play. Resulting electrocardiograms were analysed with respect to heart rate and changes in rhythm. The results indicate that squash increases the heart rate to 80% of an individual's predicted maximum ...

Perhaps the most striking aspect of gambling behavior is that people continue to gamble despite persistent failure. One reason for this persistence may be that gamblers evaluate outcomes in a biased manner. Specifically, gamblers may tend to accept wins at face value but explain away or discount losses. Experiment 1 ...

The present investigation utilized a unique, variable ratio schedule of reinforcement (the "bathroom game") to treat a 10-year-old encopretic male. Dependent measures included confirmed incidents of (a) soiling and (b) appropriate bowel movements monitored across an ABAB design (Baseline 1, "Bathroom Game 1", Baseline 2, "Bathroom Game 2") with one-year ...

The purpose of this study was to describe the anthropometric and physiological parameters that apply to a USA amateur rugby union club team. Fifteen players who were members of the club's first team were evaluated for body composition, muscular strength, power and endurance, flexibility, anaerobic power, anaerobic capacity, and cardio-respiratory ...
Smith D J - - 1982
In order to establish baseline data and to prescribe training programmes to off-set weaknesses, selected measures of aerobic fitness (VO2max), muscular power (peak torque and watt output) and performance times on-ice were collected on the Canadian Olympic Hockey Team (1980). VO2max values (54 ml. kg. min) were similar to other ...

A battery of 26 tests was administered to professional soccer players (n = 31) at 3 points during the competitive season. Significant changes from start to mid-season were limited to improved muscular power, increased resting heart rate (fH), decreased force expiratory flow (FEF) and ankle mobility. No further changes with ...

Many Canadian adults play Old Timer hockey to improve and/or maintain their cardiorespiratory fitness. This review examined the intensity and duration of play that characterizes adult noncontact hockey. The exercise intensity was assessed by continuously monitoring the heart rate response via telemetry. The duration of play was studied utilizing time-motion ...
Paterson D H - - 1979
The purpose of this review paper was to analyze the cardiorespiratory demands involved in playing ice hockey. Heart rate (HR) monitoring, by radiotelemetry during actual game performance, has indicated near-maximal cardiorespiratory efforts for the 2 1/2 to 3 minute on-ice shifts. Analyses of the temporal characteristics of the game, and ...

The relative risk of death among school and college varsity football players was calculated as a replication of a statistical exercise published a decade earlier. The purpose of the original exercise had been to demonstrate the epidemiological necessities and pitfalls in using fatality data to approach the hazardousness of sport. ...

The purpose of this study was to evaluate the physiological functions of a professional soccer team in the North American Soccer League (NASL). Eighteen players were evaluated on cardiorespiratory function, endurance performance, body composition, blood chemistry, and motor fitness measures near the end of their competitive season. The following means ...

Hooded rodents were tested in an emotionality condition and two competitive "dominance" conditions. It was found that stable rankings of subjects within the test groups could be established for each of the three conditions. Significant negative correlations were also found between a subject's "emotionality" ranked in a group and his ...
Reilly, T.
Observations were made every 4 h on 2 teams during 91 h 45 min of 5-a-side soccer to investigate stresses on players. Variables monitored were subjective fatigue, state anxiety, grip strength, heart rate, activity, urine protein concentration and liquid intake. Circadian functions were identified in all variables except protein urine ...
