استراتژی فیزیولوژی ورزش
1- اگر شدت نسبتا ثابت باشد و حجم پایین بیاید،
هیچگونه تاثیر منفی فیزیولوژیک وجود ندارد. احتیاط:
فواید: تسهیل ریکاوری
تسهیل بازسازی ذخایر انرژی
2- تغییر دروقت برنامه (ذخیره پتانسیل خواب)
پیشنهاد: اجازه استراحت بدون ترس از افت اجرا
رعایت ویژگی ورزش
برونداد: حداقل %3 افزایش در اجرا پیش بینی می شود.
Training spesificity
Training adaptations will be viewed as specific to imposed demands placed on participants.
. Henry (1950) proposed the specificity hypothesis, suggesting
that the attributes that underlie an activity are specific to that activity and not
transferable (task-specific). Sawyer et al. (2002) suggests that an attribute is
the underlying capacity within an individual, which allows for the expression
of skill (these are presently viewed as genetically predisposed and typically
unaffected by practice). The statistical evidence highly supports these
concepts (Sawyer et al., 2002).
It is important to understand that greater transfer, even at the level of energy
systems, will be realized when training is specific to the criterion task. For
example, riding the stationary bike will produce cardiovascular adaptations,
but they will not enhance the extraction of the extra oxygen delivered when
training the upper extremities (known as arterial venous difference).
in order to maintain training induced improvements, the athlete must train specific to the criterion task. That is, if you are a swimmer, you need to swim during a taper. Moreover, exercises within a sport also are very specific.
مثال:
For instance, if an athlete plans to maintain or improve his or her squat, bench press,
and dead lift during a taper, the athlete would need to practice all three lifts.
چگونگی انجام تمرینات
توجه: در Taper بیشتر حجم کم می شود،ولی کاهش در بار تمرین می تواند در کاهش هر کدام از مولفه های موثر بر بار تمرین یعنی حجم،شدت یا تکرار تمرین،حاصل گردد.
کاهش شدت تمرینات
: کاهش بار تمرینات کاهش حجم تمرین
کاهش تکرار تمرینات
WMAX and VO2MAX can be maintained in well trained cyclists for a period of three weeks, by reducing both volume and intensity to <70% VO2MAX. This contradicts the findings of Hickson et al,13 who concluded that a high training intensity (70– 100% of the normal training load) is an essential requirement for maintaining physiological adaptations gained by endurance training.
Figure 1 (A). Training history of conference group, n = 13. ■ Depicts high
intensity training. □ Depicts easy to moderate training intensity. Each period of
training represents one week of training: HV, high volume; Week1, first week of
taper; Week2, second week of taper; Week3, third week of taper; Peak, week of
conference championship meet.
