After training period estimated VO2max increased only significantly for GCOM (4,6%, p=0.01). The same authors (Santos et al., 2011b) also compared the effects of an 8-week training period of resistance training alone (GR), or combined resistance and endurance training (GCOM) on body composition, selleck chem EPZ-5676 explosive strength and VO2max adaptations in a group of adolescent schoolgirls. Sixty-seven healthy girls recruited from a Portuguese public high school (age: 13.5��1.03 years, from 7th and 9th grades) were divided into 3 experimental groups to train twice a week for 8 wk: GR (n=21), GCOM (n=25) and a control group (GC: n=21; no training program). Anthropometric parameters variables as well as performance variables (strength and aerobic fitness) were assessed.
No significant training-induced differences were observed in 1 kg and 3 kg medicine ball throw gains (2.7 to 10.8%) between GR and GCOM groups. Therefore, concurrent training seems to be an effective, well-rounded exercise program that can be prescribed as a means to improve muscle strength in healthy schoolboys. Moreover, performing simultaneously resistance and endurance training in the same workout does not impair strength development in young schoolboys and girls, which has important practical relevance for the construction of strength training school-based programs. Strength vs. Detraining: Elite Team Sports The maintenance of physical performance during a specific detraining period (decreased in RT volume and/or intensity) may also be explained by the continuation of specific sport practices and competitions and, simultaneously, by the short duration of detraining itself (decreased in RT volume and/or intensity).
It is unclear whether the inconsistency of results between different studies involving different sports is due to methodological differences, different training backgrounds, or to different population characteristics. For example, Kraemer et al. (1995) observed that recreationally trained men can maintain jump performance during short periods of detraining (6 weeks). These researchers argued that other factors like jumping technique may be critical for vertical jump performance and may have contributed to the lack of change in jump ability. Marques and Gonz��lez-Badillo (2006) found that professional team handball players declined in jump ability during a detraining period (7 weeks), though not significantly so.
This could suggest that game-specific jumping is a better means of positively influencing jump performance. It might be further inferred that game-specific jumping better promotes jump performance amongst those sports where jumping is fundamental. These findings also corroborate our personal professional experience. In fact, reducing ST volume Anacetrapib for a short time (2�C3 weeks) is not synonymous with performance decline. Occasionally, performance would even increase or at least remain stable.
