| Resumo: | High intensity functional training (HIFT) is characterized by high volumes and high training
intensities. HIFT aims to increase the physical capabilities of practitioners, however strategies
are needed to minimize injury rates and enhance performance. Therefore, the aim of the present
study was to analyze the internal training load, performance and asymmetry between members
in high intensity functional training practitioners. In the first study the the sample consisted of
31 HIFT practitioners (14 men and 17 women) with different fitness levels. In the second study,
the sample consisted of 24 amateur athletes (13 men and 11 women). For the first study the sum
and average weekly loads were recorded for the calculation of monotony, strain and acute:
chronic workload ratio (ACWR). In addition, practitioners performed jump, sprint, and
handgrip strength tests. For the second study jumping tests and sprint were performed. In the
first study, training monotony decreased only in the beginner group only at week 4 (CI95% =
0.006 to 0.292; p = 0.03) and 5 (CI95% = 0.038 to 0.396; p = 0.01) compared to week 1. In
addition, only the beginner group showed increased performance only in vertical jump against
movement (CI95% = 0.005 to 0.047; p = 0.016) and relative power (CI95% = 0.181 to 2.607;
p = 0.026). In the second study, it was observed that asymmetries do not seem to affect
performance attenuation. On the other hand, overall asymmetry of 9.5% in women and 9.3% in
men was observed. We concluded that the ITL presented variations of greater and smaller
magnitude between weeks with differences in monotony only for beginners. Additionally, only
the beginner group showed an increase in performance. It was observed that asymmetries
between limbs do not seem to be related to lower performance in the tests of performance.
However, asymmetries above 15% may increase the chance of injury. |
