Football Plyometric and sprint training on Hormones and Fitness elements among underweight College students

The purpose was to examine mixed football plyometric with sprint training on hormone and fitness elements of college students. Twenty-six underweight males 18 to 19 years with BMI < 18.5 kg/m2 and FFM 40-55 kg were distributed to Training Group 1 (TG-1; FFM-40-45kg, n = 12) and Training Group 2 (TG 2; FFM-46-55 kg, n = 14). The tests were Physical Characteristics, triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), speed (20,40, 60 m run), standing long jump (SLJ), sit-ups, agility and sit and reach parameters at pre and post-test. TG 1 & 2 performed plyometric drills followed by sprinting short distances and football matches. The training was for 6 weeks, 2/W and 40 minutes per session. Independent and paired t-test were statistical tools with level of significance at P <= 0.05. The results showed that TG-1 and TG-2 increased by 4.6, 4.4, 4.6, 3.8, 29.4, and 12%, and 4.6, 5.5, 3.4, 3.7, 21, and 13% in BM, BMI, FFM, SLJ, sit-ups, and sit & reach respectively (P <= 0.05). TG-1 dropped by 7.2, 3.6, 3.5, and 23.1% in 20m, 40m, agility, and FT3. The TG-2 reduced in 20m, 40m, 60m, agility, and FT3 by 6.5, 4.8, 4.0, 4.1, and 11.4%, respectively (P <= 0.05). It was concluded that mixed football plyometric with sprint training has an effect on power, muscular endurance, flexibility, speed, and FT3 of two groups of lean college male students. Both training groups had similar outcomes in most of the study variables with respect to the FFM.
