Sixteen physical education students participated in this study, 10 males (23.5 ± 1.4 years, 176.1 ± 5.3 cm y 73.2 ± 6.1 kg) and 6 females (24.3 ± 2.2 years, 163.3 ± 5.8 cm y 60.7 ± 6.4 kg). First, we measured the dynamic strength in the half squat exercise with a test of maximal repetitions (between 3 and 12 repetitions, with 3 different load levels). Afterwards, we determined the IMR by extrapolation of the semilogaritmic relationship load/in number of repetitions. Then, the subjects followed a 6 weeks training program to improve the maximal dinamic strength (3 sesions/week), with an initial load per week of 12.215 ± 6.852 kg and an ending week load of 19.416 ± 13.289 kg. As a result of the training program IMR was improved by 33.9 ± 19% (p < 0.001), while the energetic cost of cycling, measured at 5 different load levels, decrease by 8.0 ± 5.2% (p < 0.001). Additionally, the corrected medial thigh circumference increased by 1.8 ± 2.7% (p < 0.05). The strength gain correlated with the increment in the corrected medial thigh circumference (r = 0.65, p < 0.05). Therefore, the improvement of the maximal dynamic strength in the half squat exercise can account for a decrease of the energetic cost of cycling.||URI:||http://hdl.handle.net/10553/48348||ISSN:||0212-8799||Source:||Archivos de Medicina del Deporte[ISSN 0212-8799],v. 15, p. 17-22|
