Today’s world is soadvanced that each facet of life is dominated by science and technology. Exercise science associated sports aren’t an exception to that. Technology has forever modified our world, and within the method considerably hyperbolic the importance of menstruation and dominant performance relevant to psychological and physiological variables. Sport science incorporates a vital role in distinguishing, monitoring, and developing young gifted athletes (Williams & Reilly, 2000). For best practices and success, coaches got to perceive the complicated processes in developing athletic experience.

Amongst others, systematic coaching and well-planned programs could also be vital in youth development programs (Williams & Reilly, 2000). Researchers additionally incontestable that measurement, physiological, and ability attributes may be accustomed predict anticipated skills and experience in sports (Hoare &Warr, 2000). Additionally, prediction may be complemented with continuous measuring of physical, cognitive, and sensory activity skills, intrapersonal and social characteristics, and emotional stability (Nideffer et al, 2001).

A player profile is associate in nursing all- spherical image of the individual player-looking at every attribute. Naturally, the relevant properties for an American Footballer are those, that the work load analysis has well-tried to be important importance to the sport of soccer. The drawing of psychophysical profile of individual player offers crucial data regarding the coaching condition of the player and therefore the ability to utilize the optimum technical and plan of action properties of the player on ground. These parts move with each other and reorganized. These parts move with each other and are organized by the goal into a self-regulative system so all parts of the system move in such some way to produce the goal of the activity. Throughout the performance of the activity discrepancy are often found between real provider of activity and prescribed provider of activity. Regulation of diseased person physiological condition is provided through feedbacks of the system to scale back or eliminate the

The purpose of the present study is to construct a psycho-physiological stress profile during various stages of training for adolescent American Football players.

The subordinate purpose of the study is to find out.

1. Psychological profile such as mental toughness, coping skills and anxiety of American Football players during training stage or period.
2. Physiological profile such as calories burned and EPOC (Excess Post Exercise Oxygen Consumption) at various stages or periods of training.

1. To access the psychological strength of American Football players.
2. To have a deep understanding of exercise psychology.
3. To understand the role of stress during training.

Based on the literature found, it is hypothesized that:

1. Individual differences would be there for both psychological and physiological profiling.
2. There would be significant differences in the oxygen uptake and calories burned by American Football players at various stages or period of training.

KlinKhir (2009) examined character and speed of restoration of psycho physiological functions when application of varied varieties of anaesthesia in conditions of a "one-day" stationary. The frequency of operative interventions, performed in step with the "one-day" stationary technology is rising each day. The patient’s area unit select in accordance with standard strategies, whereas physical state of a patient and also the any operation volume taking part in the leading role. However, in half-hour of patients within the early surgical amount and in ten.4% within the late postoperative amount the high psychic functions disorders occur, that area

1. The first hypothesis stated that there would be significant differences in the oxygen
