The aim of this study is to determine the acute effects in sodium, potassium and chlorine levels in the plasma concentration of sportsmen in training types of maximal strength (MS), power endurance (PE) and interval run (IR), to find out the mineral requirements of professional sportsmen. The study included 24 male professional basketball players with the average of 22 years. In order to examine the effects of different training models, participants were divided into three groups (n=8 in each group); maximal strength (MS), power endurance (PE) and interval run (IR). In blood samples collected after different types of training, in IR and MS while Na and Cl levels were increasing, K levels decreased, only the increase at NA level in IR found out significant. While in PE, all of parameters (Na, K and Cl levels) were increasing, only the increase at C1 level observed significant. Besides, Na and C1 levels increased after each of the three training type (IR, MS and PE), while the K level (PE) was increasing in the training group, decreased in (MS) and (IR) group. Keywords: Endurance; Running; Some elements; Strength

Eight college students enrolled in group therapy for stuttering were divided into two equal groups for 20 weeks. The training group supplemented therapy with endurance running and calisthenics three days per week. The subjects were tested prior to and at the conclusion of the training on a battery of stuttering tests and cardiovascular measures taken at rest, after stuttering, and after submaximal exercise. There were no significant differences (0.05 level) prior to training. At the conclusion of training, the training group was significandy better in cardiovascular response to exercise and stuttering. Although physical training did not significantly aid the reduction of stuttering as measured in this study, training did cause an increased ability to adapt physiologically to physical stress and to the stress of stuttering.

The main aim of the present study was to compare the effects of flywheel strength training and traditional strength training on fitness attributes. Thirty-six well trained junior basketball players (n = 36; 17.58 ± 0.50 years) were recruited and randomly allocated into: Flywheel group (FST; n = 12), traditional strength training group (TST; n = 12) and control group (CON; n = 12). All groups attended 5 basketball practices and one official match a week during the study period. Experimental groups additionally participated in the eight-week, 1–2 d/w equivolume intervention conducted using a flywheel device (inertia = 0.075 kg·m−2) for FST or free weights (80%1 RM) for TST. Pre-to post changes in lower limb isometric strength (ISOMET), 5 and 20 m sprint time (SPR5m and SPR20m), countermovement jump height (CMJ) and change of direction ability (t-test) were assessed with analyses of variance (3 × 2 ANOVA). Significant group-by-time interaction was found for ISOMET (F = 6.40; p = 0.000), CMJ (F = 7.45; p = 0.001), SPR5m (F = 7.45; p = 0.010) and T test (F = 10.46; p = 0.000). The results showed a significantly higher improvement in CMJ (p = 0.006; 11.7% vs. 6.8%), SPR5m (p = 0.001; 10.3% vs. 5.9%) and t-test (p = 0.045; 2.4% vs. 1.5%) for FST compared to the TST group. Simultaneously, th FST group had higher improvement in ISOMET (p = 0.014; 18.7% vs. 2.9%), CMJ (p = 0.000; 11.7% vs. 0.3%), SPR5m (p = 0.000; 10.3% vs. 3.4%) and t-test (p = 0.000; 2.4% vs. 0.6%) compared to the CON group. Players from the TST group showed better results in CMJ (p = 0.006; 6.8% vs. 0.3%) and t-test (p = 0.018; 1.5% vs. 0.6%) compared to players from the CON group. No significant group-by-time interaction was found for sprint 20 m (F = 2.52; p = 0.088). Eight weeks of flywheel training (1–2 sessions per week) performed at maximum concentric intensity induces superior improvements in CMJ, 5 m sprint time and change of direction ability than equivolumed traditional weight training in well trained junior basketball players. Accordingly, coaches and trainers could be advised to use flywheel training for developing power related performance attributes in young basketball players.

Renal Excretory Function

Administration of Diamox by ingestion or injection to adult fasting female dogs consistently produced an acute increase of approximately 1 mg % in the plasma concentration of calcium. At the same time there was an increase in the plasma phosphate and chloride concentration and a decrease in total plasma content of carbon dioxide of Diamox-infused dogs. Diamox did not affect the plasma concentration of calcium, chloride or bicarbonate if renal excretory function was abolished prior to its administration. Infusion of Diamox produced a prompt rise in the urinary excretion of sodium, potassium, calcium, phosphate, citrate, chloride and water in fasting female dogs. The effect of Diamox on the fasting concentration of calcium rendered unsatisfactory the interpretation of data concerned with a study of its effect on the disappearance of injected calcium. However, intravenous injection of small amounts of sodium carbonate was found to produce a definite delay in the rate of disappearance of injected calcium.

Purpose of this study was to compare effects of general strength training with combined maximal strength and plyometrics training. Twelve young ice hockey players were examined and intervened 4-week general strength training (EX1) at first and consequently 4-week, combined training (EX2). Combined training consisted of maximal strength workouts with 2-4 repetitions on 85-95% 1RM and subsequent application of plyometrics workouts with 6-10 repetitions. The training group performed 2 sessions per a week in 3 sets of exercises. The measurements were assessed before, between and after periods and consisted of specific test performed on ice and non-specific tests off ice. The results showed that in EX2 period SJ improved from 33,3 ± 2,89 cm to 34,35 ± 2,80 cm by 1,05 cm (3,2%; p<0,01); CMJ from 36,51 ± 4,39 cm to 37,84 ± 4,36 cm by 1,33 cm (3,6%; p<0,01). Also in EX1 period SJ was changed from 32,48 ± 3,65 cm to 33,3 ± 2,89 cm (p<0,05). Anaerobic alacticpower (AAV) changed significantly in EX1 period from 42,09 ± 4,48 W.kg-1 to 42,72 ± 4,61 W.kg-1 (p<0,01) afterwards in EX2 period to 43,78 ± 4,44 W.kg-1 (p<0,01). In jumping performances we measured in both periods significant improvements; standing long jump (SZM) in EX1 period from 246,25 ± 11,07 cm to 249,17 ± 10,32 cm (p<0,01) then in the end of EX2 period 253,58 ± 9,83 cm (p<0,01). Standing triple jump (3SK), agility run (10x5) and all specific test on ice were significant changes recorded only in EX2 period. 3SK from 722,42 ± 29,58 cm to 727,50 ± 30,64 cm; 10x5m from 17,00 ± 0,57 s to16,90 ± 0,57 s (p<0,01); on ice speed tests (1x36m) from 4,95 ± 0,10 s to 4,88 ± 0,09 s by 1,4% (p<0,01); (6x9m) from 13,73 ± 0,48 s to 13,63 ± 0,51 s by 0,8% (p<0,05); in speed endurance ice hockey skating test (Okr) form 14,79 ± 0,18 s to 14,67 ± 0,20 s o 0,8% (p<0,05). Skills ice hockey test parameters (Sla) did not changed significantly in EX1 neither in EX2 period. It could be concluded that both periods had effect on motor performance enhancement, but EX2 training period was more sufficient for improvement in speed-strength abilities especially in specific condition on ice.

Abstract The aims of this study were: (i) to describe weekly variations of acute load (AL), acute:chronic workload ratio, delayed onset muscle soreness (DOMS), and fatigue; (ii) to analyze variations of weekly workload and well-being in three periods of the season (P1, P2, and P3); and (iii) to analyze the relationships between workload and well-being measures. Fifteen professional basketball players from a first-league European club were monitored throughout the season using the CR-10 Borg scale and the Hooper questionnaire. Weekly AL and acute:chronic workload ratio (ACWR) were weekly calculated for monitoring of the internal load. In addition, DOMS and fatigue values were weekly calculated. Greater AL, DOMS, and fatigue values were found during the early season, and the highest ACWR value was found during the second period. Overall, AL presented large correlations with DOMS (r=0.60) and fatigue (r=0.62). The results of this study indicate that load is higher in the first period and then decreases throughout the season. The results also showed that AL is more closely related to well-being parameters than ACWR.
