Sentences with phrase «peak knee and ankle»

In contrast, peak knee and ankle angles do not differ between straight barbell and farmers» walk bar deadlifts or between conventional and sumo deadlift styles, while peak knee angles are more acute in hexagonal barbell deadlifts compared to straight barbell deadlifts.

Sch √ ∂ nborn concluded that premature damage to the spine, hips, knees and ankles combined with psychic stress to eliminate many promising youths from German tennis long before they reached their peak.

In the second pull phase, peak hip, knee and ankle joint angular velocities are around 420 — 470, 280 — 400, and 210 — 370 degrees / s, respectively (Gourgoulis et al. 2002; 2009; Akkuş, 2012; Harbili, 2012; Harbili & Alptekin, 2014) and are not affected by the load used (Harbili & Alptekin, 2014) or whether the lift was successful (Gourgoulis et al. 2009).

Using weightlifting shoes and running shoes both lead to more acute peak ankle angles than using no footwear, while cues to prevent the knee from moving forward over the toes lead to less acute peak ankle angles.

Enoka (1988) explored hip, knee and ankle joint power outputs in competitive weightlifters during the first pull and transition phases and reported that joint peak power output did not alter with increasing load at the hip, knee or ankle.

Although peak velocity is less well - studied, linear barbell velocity reduces with increasing load (Suchomel et al. 2014a), as do the angular velocities of the hip, knee and ankle joints (Suchomel et al. 2014e).

Exploring the effects of training variables, Kellis et al. (2005) found that joint angles differed between relative loads but did not identify how the individual hip, knee and ankle joints differed; however, List et al. (2013) found that increasing load caused peak ankle angle to become more acute, from no load to 25 % of bodyweight, to 50 % of bodyweight.

Exploring the effects of cues, Hirata and Duarte (2007) found that peak ankle flexor moments were smaller when the knee was cued not to pass forward of the toes compared to a conventional technique.

Exploring the effects of training variables, Kellis et al. (2005) found that joint angles differed between relative loads but did not identify how the individual hip, knee and ankle joints differed; however, McKean et al. (2010) reported that peak hip angle was more acute with load compared to no load, while both List et al. (2013) and Gomes et al. (2015) reported that peak hip angle became less acute with heavier relative loads.

Exploring the effects of cues, Hirata and Duarte (2007), Lorenzetti et al. (2010) and List et al. (2013) all found that peak ankle angles were less acute when lifters were visibly cued to prevent the knee from moving forward over the toes, compared to when they were allowed to lift normally.
